In general, bicycles are in the spotlight as rides and leisure sports, and in particular, in recent years, bicycles are being used for energy saving in line with high oil prices.

However, despite the recent explosive growth of bicycle populations, infrastructure such as bicycle lanes is inadequate, and therefore, most people drive on general roads, and especially at night, when compared to daytime. This falls sharply, so more and more care must be taken when driving.

In addition, even when driving in narrow alleys, the direction of the bicycle is not known, so it is most often necessary to run in a state where the hazards are scattered.

Thus, a number of technologies including Patent Publication No. 2005-0052068 have been disclosed, and there have been efforts to secure safety of passengers, pedestrians, drivers, etc. by displaying driving directions of bicycles.

By varying the speed, the speed sensor is configured to change the direction and the speed is installed in the operating part to enable the driver of the vehicle and the bike following the sudden braking to increase the safety of the operator.

In addition, when the surrounding environment becomes dark due to the light sensor installed in the operating part, the emergency lamp flashes continuously to notify the vehicles coming from the rear to prevent the accident. In particular, when the emergency lamp flashes suddenly, when a sudden braking to be turned on for a certain time, this also adds a function to prevent accidents.

As such, bicycle-related technologies are improving day by day, and it can be seen that much effort is being made to improve the convenience of use and appearance quality.

However, among the technologies provided for the convenience of using the bicycle, the direction indicator lamp is wirelessly handled by one-way communication, so there is no way to properly control the error when the error occurs. Even if it is discharged and cannot operate, the transmitter transmits only the designated command code, so it is impossible to check whether there is any abnormality. If such a phenomenon occurs while driving, it cannot perform its function as a direction indicator, which is the same as without a direction indicator. As a result, there are big blind spots that can lead not only to safety accidents but also to large accidents.

This phenomenon is not only a wireless problem, but also a problem that may be accompanied by a wire.

In addition, the proliferation of the wireless communication method causes interference when several cars run at the same time, causing malfunctions, which also has the disadvantage of creating another safety blind spot.

At this time, the main controller is also characterized in that it is detachably installed on the handle.

In addition, the main controller is characterized in that a buzzer for transmitting a warning sound when the outside of the communication radius with the LED controller is further installed.

In addition, the main controller and the LED controller has a communication format including an ID code, the ID code is characterized in that the product information code consists of 2 bytes, extension code 1-2 bytes, serial number 4 bytes.

According to the present invention, the abnormality of the indicator light is checked in real time through two-way communication, and communication using a unique ID code does not interfere with the surrounding radio waves, so there is no risk of malfunction. By alerting in case of theft, you can get the effect of three stone trillion which performs faithfully anti-theft function.

Figure 2 is a block diagram of the configuration of the indicator light control apparatus of the bicycle according to the present invention.
3 is an exemplary view of an ID code used in the indicator light control apparatus of the bicycle according to the present invention.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

As shown in Figure 1 and 2, the indicator light control device of the bicycle according to the present invention and the main controller 200 is installed around the handle 100 of the bicycle for convenience of operation, and the front of the bicycle, preferably Includes an LED controller 300 installed in place of the handle shaft 110 or behind the bicycle, preferably under the saddle 120.

The main controller 200 and the LED controller 300 perform bidirectional communication with each other.

In addition, the LED controller 300 is shown only one diagrammatically for convenience of description, it is preferable to use two of the same configuration for the use of both the front light / the rear light.

However, in the present invention, only one will be described as an example.

In addition, the LED controller 300 includes an LED lamp, the arrangement is the same as the example of Figure 1, by controlling the flashing of a plurality of these LED lamps, respectively, can be used as a front light, a back light, if necessary, the front In the case of the lamp may be used as a headlight, a turn signal, a stop light, and in the case of a rear light may be used as a taillight, a turn signal, a stop light.

In particular, the LED lamp is more preferably to be applied by selecting the medium brightness or high brightness according to the function of the indicator.

This is only the shape and design shown in the prior art Patent No. 0910402 can be seen that the practical function is similar.

However, the present invention is distinctly different from the previously disclosed techniques, which are in bi-directional communication and also include a specific ID code to prevent malfunctions (inoperation, external interference, etc.), as well as the status of the current indicator light. It can be checked in real time through the LCD, and it also includes an anti-theft function by issuing an alarm in case of theft.

More specifically, as shown in FIG. 2, the main controller 200 includes a main controller 210.

The main controller 210 is driven by receiving power from the battery cell 230, and performs all control actions required for the main control.

The switch input unit 220 includes each control switch.

Here, each control switch means a headlight switch, a taillight switch, a left-right support light switch, and the like, and in particular, a proximity switch may be installed in the steel wire for the brake to turn on the brake light.

Therefore, the switch input unit 220 is a portion for inputting the signals generated from each of the control switch to the main controller 210, the main controller 210 according to the input signal of the switch input unit 220 is a corresponding control switch Will detect the on / off and execute the appropriate command.

That is, the main controller 210 detects an input signal of each control switch according to the on / off signal of the corresponding control switch, and transmits a command code to the signal conversion unit 250.

The transmitted command code converts the low voltage of the logic level into the RS-232C signal in the signal converter 250.

In addition, the battery cell 230 is preferably a removable form as the main power source of the main controller 200, a variety of batteries, such as mercury cells, other rechargeable cells, as well as AAA type batteries can be used, the cover for protection It is desirable to have.

At this time, the power switch 240 may be further provided to turn off the power supply of the battery cell 230 to turn on / off the power supply itself, the power switch 240 is the main controller 200 It is preferred to be installed on the side of the.

In addition, a wireless transmitter and receiver 260 is connected to the main controller 210. The wireless transmitter and receiver 260 converts the command code converted from the signal converter 250 into an RS-232C level through an RF module. Transmit to radio signal.

In addition, after transmitting the command code, the wireless transmitter / receiver 260 waits until a command acknowledgment signal is transmitted from the first or second LED controllers 300 and 400.

Upon receiving the confirmation signal, the signal is transmitted to the main controller 210 in the case of the signal converter 250.

At this time, the main controller 210 determines whether it is a command reception confirmation signal corresponding to the command code, and if the code is correct, the control cycle is finished and the LED 350 associated with the lamp currently being lit is turned on.

In addition, the radio module basically uses RF communication, has a unique communication protocol, and may use short-range wireless communication such as ZIGBEE or WPAN.

In addition, the LCD 270 displays the operating state of the current equipment in real time, allowing the occupant to immediately check the current state of the indicator light.

In this case, the operation state means displaying the lighting state of each lamp, battery, alarm (buzzer), etc. in the form of a letter or an icon.

In addition, the buzzer 280 generates a buzzer sound under the control of the main controller 210 when an error occurs during use (eg, battery LOW), and also controls the main controller 200 and the LED controller 300 to a distance greater than or equal to a predetermined distance. The buzzer sounds even when it is dropped.

Herein, the main controller 200 may be configured to be easily detachable and may be configured to detach and carry the main controller 200 if necessary.

Meanwhile, the LED controller 300 includes an LED controller 310.

The LED controller 310 analyzes a command code after receiving a wireless signal transmitted from the main controller 210 of the main controller 200, and turns on the corresponding LED 350 to check the command reception confirmation code. Retransmit to the master controller 200.

In addition, the LED controller 310 is also provided with a wireless transmitter and receiver 320, which receives the command code of the main controller 200 and transmits it to the signal converter 360.

The signal converter 360 changes the received command code to a logic level and transmits the command code to the LED controller 310.

In addition, the LED controller 310 checks the command code and then drives the output port to light the LED 350 corresponding to each command, and controls the LED 350 to the rear including taillights, traffic lights, stop lights Perform front light functions, including headlights, headlights, taillights and turn signals.

In addition, the battery cell 330 is the same as the main controller 200 described above, it may also be provided with a power switch 330 to directly turn on / off the power if necessary.

In addition, the above description is limited to the case of wireless, but it is not necessarily limited to the wireless, and in the case of a wired, the rest of the configuration is the same except for the wireless transmitter and receiver, and must be connected by at least three wires for communication. To connect at least two LED controllers.

In addition, the communication method may be connected by three or less lines such as RS-232C or I2C, and may have a specific protocol to eliminate interference between devices.

As such, the present invention uses two-way wireless communication, whereas the communication method related to the indicator light used in most existing bicycles is unidirectional.

That is, conventionally, the transmitting device transmits a predetermined command code, and the receiving device receives the predetermined command code and performs only a corresponding operation.

Therefore, since the transmitting apparatus cannot know the operation state of the receiving apparatus, the user has no way of confirming this.

For example, even if the battery of the receiving device is discharged and cannot operate, the transmitting device transmits only a predetermined command code, but the receiving device cannot receive it. If the problem occurs during driving, especially at night, it can be a fatal danger.

However, in the present invention, since the two-way communication is made as well as the status is immediately displayed on the LCD, the occupant can check this in real time, so the immediate action is possible, thereby reducing the risk.

In addition, near field communication uses LED controllers and main controllers to perform bidirectional communication periodically, so if necessary, the thief can take off the bicycle when the user takes off the main controller and holds it within range. If you move outside of the communication range, the buzzer will sound an alarm as soon as it goes out of range, and the anti-theft function can be performed.

Furthermore, since the command code system to transmit / receive assumes the main controller and the LED controller as one set and includes a fixed ID code, even if multiple devices are used simultaneously in the surroundings, there is a protocol that does not interfere with other sets and does not malfunction. do.

This is possible because of bidirectional communication with ID code.

That is, since one set of device-to-device communication has its own ID code, if the main controller and the LED controller have different ID codes, communication is impossible and thus cannot be used.

In this case, the ID code is preferably stored in the flash memory inside the microchip.

Finally, the command code and communication format are shown in FIG.

As shown in FIG. 3, the transmission / reception format may be in the form of transmitting ASCII values in a predetermined order, and may include a check sum code in the format for more accurate transmission and reception.

In addition, the ID code includes a serial number determined at the time of product production, and may include a predetermined product information code according to the product model.

As a result, the present invention can be more secure and accurate control, even if the existing indicator including the controller of the communication method, there is no interference with the peripheral device, it is expected that the utilization of the real-time indicator can be very large.
