The sound alarm system anticreeping for a bicycle. Bicycle alarm with feedback. Description of the bicycle alarm

For a long time, many owners Vehicle realized that an excellent tool against theft is an alarm. It is also installed on the bike. High-quality technologies provide protection from an intruder, not only preventing the theft of property, but also attracting the attention of others.

Types

There are several categories of electronic systems. One of them is a siren. She is able to attract maximum attention from passing people. A beep at high volume will scare away the thief. If an intruder tries to remove or disable it, the sound will only increase.

An equally popular method of protection is a special system with a control panel. It works like the previous one. The difference lies in the fact that you can turn off or turn on the sound signal at a distance only using the remote control.

A smart bike alarm is one that has a code blocker. How does this system work? It fixes the lock until the owner enters the correct combination of characters.

Bicycle alarm with feedback is no less popular. It will not only scare away the intruder with a loud long alarm, but will also send information about this to a special reception panel.

Those people who have purchased an expensive vehicle and are afraid for its safety should install several alarms at once. Then the attacker will prefer to bypass the bike, otherwise it will take a long time to mess around, and not the fact that it is successful.

What opportunities does a bicycle alarm with a remote control open?

How does this type of protection scare off an intruder? During extra fuss next to him, the bike starts to make a loud noise, the threshold of which is 120 dB. It should be noted that this sound signal for the ears is considered painful.

Thanks to special settings, you can slow down the alarm. This is done so that the bike does not start to "scream" with the vibration that appears due to a passing car. Accordingly, the owner will not often have to come to the parking place in the event of a false alarm. This alarm not only works with a loud sound. It is also capable of sending alerts to the control panel. If a person always uses it and keeps it close, he will quickly be able to understand when his vehicle needs protection.

Bicycle GPS device

An excellent alarm for a bicycle with a key fob is one that is able to determine the location. She hides in the steering column. Has the shape of a flask. Significantly saves battery charge, as it works only while driving. When a bike is stolen, it can be easily found via satellite, and because of high level secrecy, the offender will not guess anything.

smart lock

At the moment, smartphones are quite popular. There is also no need to talk about the wide demand for GPS navigation services - everyone knows about it. When combining two technical means- phone and module - you can easily monitor your vehicle. Previously, such systems worked only for cars, but now they are also used by cyclists.

The Lock 8 lock is a perfect example of this. It hit the market in the spring of 2014. High quality lock. By the way, this model is constantly being improved.

What are the advantages of this system? So, you can easily control the alarm blocking through the software on your phone. This is the most convenient. The data is not transmitted via the Internet, but via the Bluetooth module. This is an additional advantage, but the distance between the bike and the phone should be small. The last remark, of course, is a significant minus, although for many it is not particularly critical. The key can be transferred to the smartphone of any person if you need to transfer the vehicle to someone else. In case of theft, this lock will be able to determine its location - it has a built-in navigation system and a communication module. The blocker does not have batteries.

Disadvantages of anti-theft alarm

A bicycle alarm lock has its drawbacks. What? First you need to notice that a lot of energy is consumed in standby mode. Why? Because the sensors are constantly in working condition and consume all the "fuel" they need. Therefore, bike owners who actively use the vehicle will have to constantly spend money on batteries. If the alarm has a battery saving mode, then its noise signal will sound for no more than 30 seconds. It should be noted that the reviews of the owners about this moment are extremely negative. Often she falls silent at the most inopportune moment.

Also, the environment significantly affects the operation of the system. It is primarily about humidity and air temperature.

How to make a bike alarm with your own hands?

You do not need to have outstanding knowledge and achievements in the field of radio engineering to create such a device for your vehicle on your own. You just need to have basic skills and understanding of the structure of the system. What should be used? A regular wireless doorbell will do. It should function in open mode, for this you will have to tinker a little with the correct arrangement of wires.

A similar system can be installed in the end surface of the steering wheel. If you want to improve the received version, you should replace the standard ringtone with a more powerful one. This alarm will work if the steering wheel rests on a hard surface. As soon as the bike is moved, an audible alert will immediately sound.

Of course, you need to understand that such a system is imperfect and needs to be improved. It is best to prefer factory options that were created by professionals. Their main difference is powerful and loud sound effects.

Finally

If you want to buy for yourself best model signaling device that will delight with its combination of price and quality, it is necessary to consider expensive options. They guarantee high-quality protection against theft.

How much will the device cost? The minimum cost is 300 rubles. If the owner is really worried about his vehicle, then you will have to pay more than 1 thousand. Then you don’t have to worry about the safety of your device.

If we talk about the capabilities of systems, then you need to choose the most practical options, based on your own interests. The main advantage is the control panel, which comes with some models. Thanks to such programming, it is possible at any time to draw attention to the situation with the theft of someone else's property. In addition, using the remote control, you can adjust the sound range. Sometimes its high frequencies can cause discomfort and harm to the health of not only the attacker, but also people who are nearby.

FAST Smart LED Taillight for Bicycle

A smart rear light will help warn others about an accident or unauthorized movement of the bike (or simply theft). The flashlight is photosensitive and can change the color and brightness of its glow depending on the illumination. It is based on RGB LEDs. Lantern, can be mounted on back bicycle, performing some intelligent functions. Management is carried out through a smartphone application, which we simply called "FAST". We hope this light will enhance the safety of your cycling by adding an unforgettable experience to your cycling.

Possible smart functions:

emergency communication

Cycling is a pretty unsafe activity and accidents can happen at any moment. Acceleration sensor and simultaneous motion tracking will help you get immediate help in case of an emergency. First, a strong collision or a sharp turn will cause the light to change mode, signaling an SOS signal, so you can easily be seen at night. Secondly, the smart flashlight will start transmitting information about you to your friends on their smartphones (this is the so-called emergency communication channel), letting them know that you are in an emergency and you need help. Your friends will receive a notification on the screen that they urgently need to go to the FAST application in the "SOS" section to receive emergency information about you.

Automatic brightness change

If the ISO-Auto function is activated, the flashlight will be light sensitive to ambient light. For example, when you drive into a dark tunnel or a dark place, the flashlight will automatically turn on with a bright light.

Anti-theft feature

Bicycle anti-theft devices are a big inconvenience to use, especially when you only have to leave your bike for a couple of minutes to buy a cup of coffee or small change. Thanks to our development, you will not have to tie your bike for a long time. By simply pressing the "Lock" button in our dedicated FAST app on your smartphone, you can safely leave your bike unguarded. If someone tries to steal your bike, thanks to the acceleration sensor connected to the application on your smartphone via Bluetooth, you will immediately receive an alarm. Simultaneously with the alarm, the rear light will flash brightly in different colors.

Full color LED customization

Ordinary taillights are boring! But with the use of a variety of individually configurable full-color LEDs, this is already more interesting. The taillight has eight RGB LEDs. You can customize your favorite color and pattern right through the FAST app on your smartphone! We have added such an interesting feature to the flashlight as the display of small words in the form of Morse code. For example, you can transmit your name, or the name of your favorite pet, through the lantern. In addition, if you live in countries where the law only requires a red rear light, then you can easily adjust it within the law.

Here are some possible modes of operation of the rear lights:

double flash

Roundabout Circulation

random colors

Lights passing by

breathing lamp

Red glow (for countries where required by law)

A little about the FAST application

Through the application, you can both view and change the LED flashing mode, check the driving status and much more by simply tapping on the desired function with your finger.

Available features in the FAST app

Application operation in the "Community" mode

The FAST app allows you to share locations between friends in real time. You can join a group of your friends using a two-dimensional QR code, which can be sent to you, for example, by e-mail. Once you have joined the group, you can check the location of your friends, and if someone gets into an accident, the application will immediately notify you by switching the friend's color to red.

With the FAST application, you can keep a log that will record your movements in real time, as well as allow you to calculate the driving time, average speed, calories, etc. This data can be saved or shared in in social networks Facebook, Twitter, wechat , etc.

Modern production design

How can you quickly and securely attach a light to the back of your bike? With the help of a special adjustable mount with a strap, the lamp can be easily installed on any type of frame of various bicycles.

Thanks to a special optical coating and a special geometric shape, the FAST tail light continues to reflect light even when it is turned off. In order to protect the internal electronic components, we have made rubber sealing of the body, thus making the flashlight waterproof and dustproof.

Using the button on the back of the flashlight, you can quickly change the flashing mode of the LEDs, as well as turn it off. The battery is charged by a charger with a Micro USB connector.

Specifications

The FAST rear light is equipped with 8 RGB LEDs that can display up to 16 million colors. Controlled via Bluetooth Low Energy technology, with OTA (Over The Air) support. Power is provided by a lithium-polymer battery with micro USB charging. It's all very environmentally friendly and convenient.

What's more, the FAST rear light can be used as a small night light, or as a small portable lamp!

The bike does not stand still, two wheels famously roll it in step with the times. Models are being improved, the assortment is replenished for every color and taste, devices and devices appear to improve the quality of “bicycle life”. These include an alarm that is ready to protect the bike from the evil intentions of the ubiquitous hijackers.

An alarm system with a feedback function is not just a “shout”, but a functional communication device for the owner with the bike left in the parking lot. It has a complete analogy with the car anti-theft system - the owner will be notified in time about the theft or its attempt. What is good about this device, what disadvantages it has, and we will learn about the enhanced protection of the bike later in the article.

Functions of the anti-theft system

The alarm kit with feedback includes an electronic unit, key fob, mounts and batteries. Actually, nothing complicated, the device is very simple, the settings are transparent, but instructions for adjustment and operation are included to help.

The principle of operation of the signaling system is to give a loud signal and report the theft to the owner through a key fob or remote control. Turning the alarm on and off is carried out by special buttons on the key fob.

True, at first the owner himself may forget about the need to turn off the device and be deafened by the piercing scream of the signaling. Some models have integration with a smartphone: a special application is installed through which the owner via Bluetooth will be notified in time about attempts to steal, as well as the location of the bike via GPS.

Standard bike alarm options include:

loud attracting signal up to 120 dB;
sensitivity settings for distance and time;
call via application or remote control;
additional power supply (for long stops);
notification of low batteries and disabling the alarm.

The system is usually attached to the seat tube, less often to other parts of the frame.

Remote signaling: yes or no?

It should be noted right away that the alarm system is not a cheap thing, therefore it is rational to put it on the corresponding bicycle models. Advantages of the anti-theft system:

loud signaling: on city streets, this will immediately attract the attention of passers-by and the owner himself;
remote warning system, you can leave the bike in the parking lot without a lock;
the device, although expensive, can be bought without problems - on the counter or by ordering on the Internet;
sensitivity setting.

Minuses:

the sensitivity of the alarm is also a disadvantage - the device can work with small vibrations, causing great inconvenience to the owner;
on budget models, weak mounts;
the application on the smartphone may suddenly freeze, due to which the owner may not receive an alarm signal;
high battery power consumption in passive mode.

Whether to buy a bike alarm or not is up to everyone to decide. Here it is worth considering the price of the device, the class of the bike, the frequency and duration of parking, the place of the most frequent stop.

Anti-theft alarm with lock

Combined version - a bicycle alarm with a lock. In the off state, the device works like a simple anti-theft device with keys. An active alarm system sends out alarms and alerts via bluetooth.

Alarm cable lock

The advantage of the signaling lock:

the bike is fastened;
signaling always, even when the thief tries to bite the cable;
the device is less conspicuous.

Of course, no matter how modern and reliable methods are, there is no 100% guarantee of protection - thieves have not decreased, if not vice versa. Therefore, it is worth giving some more valuable tips on how to protect your bike as much as possible in the parking lot.

Extra protection doesn't hurt

Since stopping a bike on the street is a risky business even with advanced signaling, it is not recommended to leave the bike unattended for a long time. Although the alarm is silent, it is necessary to periodically check whether your two-wheeled friend is in place.

A wireless alarm system plus a cable or U-lock lock is a more reliable option when compared to installing only an alarm. The classic rule of “fastening both the frame and the wheels” is not canceled: when fixing only the wheel, there is a risk of losing the most important thing in a bicycle - the frame and fork.

Another good recommendation for protecting a high-speed bike from theft is to set a low gear. A thief, carried away by the theft process, will not be able to immediately go far from the parking lot, and the alarm will attract more attention at low speed.

Conclusion

Bicycle alarms are a great addition to protecting your bike in the parking lot. Nevertheless, vigilance should be exercised: the device can fail, and the hijacker can remove it from the bike. It is preferable to set the maximum protection and choose proven parking spots.

- This is the least protected mode of transport, which, according to statistics, is the easiest to steal. It is worth the owner to leave the bike for a couple of minutes to go to the store, and you can be left without a bike. Therefore, we advise you to take security measures that will prevent theft and protect the bike from intruders.

The choice of safety equipment for a bicycle should be approached with all responsibility. A bicycle alarm or lock is fundamentally different in its design from car security systems. We advise you to buy a bicycle alarm with a remote control, as it has a number of advantages over other security devices.

One of effective ways protecting your bike from intruders is an alarm system with a remote control. This device will notify you in time about an attempt on a vehicle by giving a signal to the remote control, and the fraudster will be frightened by a loud sound signal that is triggered when an attempt is made on a bicycle.

The use of a bicycle alarm is recommended to all vehicle owners. The device has a compact size and is easy to install on a bicycle. Thus, you get reliable protection in those moments when it becomes necessary to leave the bike unattended.

The alarm is suitable for sports and mountain bikes. It does not weigh down the structure. And its presence does not affect the maneuverability of the bike. Such a device is a must have for those who prefer to move around the city by bike. You never know when you'll have to leave and leave your bike on the street. But the alarm system will always be ready to notify you of danger.

Bicycle alarm with remote control is designed to protect against thieves and vandalism. There is a category of people who do not want to steal a bicycle, but for unknown reasons can harm transport. In such cases, signaling takes precedence over bicycle locks, as it notifies you even if the bike remains in place, but at the same time there is an outsider nearby.

How does a bike alarm work?

Many of you probably know how a bike alarm works. Nevertheless, there are some nuances that the future owner of the device should know.

A conventional bicycle anti-theft device will rarely stop a thief, who is sometimes able to drag the bicycle away by hand. There is no perfect defense against kidnapping, but a brief alarm can scare off the occasional thief.

Proposed bicycle alarm is activated if its position is barely changed, or if it is touched. The alarm sound emitted by the piezoelectric emitter continues for 30 seconds. After the end of the first series of alarms, it repeats until the alarm is turned off.

Description of the bicycle alarm

The security alarm system for a bicycle has three main blocks: a vibration sensor, a siren activation delay timer, and an alarm sound generator.

The bicycle alarm vibration sensor is made of a rather long and flexible spring, one end of which must be soldered to a small piece of double-sided fiberglass (10 mm x 10 mm). Then this fragment must be soldered perpendicularly to the printed circuit board from the soldering side. The second end of the spring is threaded through a tinned washer, which is also soldered to the board. Thus, at the moment of impact, the spring either closes to the washer, or not, which leads to a change in the signal on the inverters DD1.1 and DD1.2.

When a positive pulse appears at the input 1 of the element DD2.1 at the same moment, a negative pulse appears at the input 2 of the same element and vice versa. The pulse from output 3, passing through the inverter DD2.2, starts a single vibrator on the logic elements DD2.3 and DD2.4, which performs 30 seconds. delay. This delay is calculated by the formula: t1 = 0.7 x R7 x C6, where R7 is in megaohms, C6 is in microfarads.

The chain of elements R4 and C3 provide a time delay after the alarm power is turned on, necessary for the spring sensor to calm down and there are no false positives. The time delay is calculated as follows: t2 = 0.7 x R4 x C3.

The sound source is a piezo emitter. Rectangular signals to the piezo emitter come from the element DD1.4. Its frequency is determined by the parameters of the elements C7, R8, R9. In order to create sufficient audio signal power, this oscillator frequency must match the resonant frequency of the piezoelectric buzzer. To draw the attention of others, the sound signal is replaced by a low frequency sound signal created by a second multivibrator.

To select a different duration of the intermittent sound of a bicycle alarm, you should select the capacitance of the capacitor C6 from 10 to 100 microfarads.
