The terminal mutual control unit is mainly composed of a PW-01 type Bluetooth module; the PW-01 Bluetooth module is a master-slave machine integrated Bluetooth transparent transmission module with the functions of transparent transmission of serial port data and ultra-low power consumption. The module is based on Bluetooth 4.0 protocol standard, and adopts a Texas instruments TICC2541 chip in America as a core processor.

The advantages of the module software are: the method adopts a master-slave integrated design, and the AT command modifies the module name, master-slave mode, transmitting power, pairing password and scanning connection appointed slave machines; the host can also remotely control the slave pin to output high and low levels, can realize the applications of ADC sampling, distance measurement and the like, and is very suitable for developing specific products according to the requirements.

the advantages of the Bluetooth module hardware are as follows: the device has the characteristics of ultralow power consumption, small volume, long transmission distance, strong anti-interference capability and the like. The Bluetooth low-power-consumption Bluetooth system supports connection of mobile phones, tablets and computers such as Android and IOS, can be widely applied to a 2.4G Bluetooth low-power-consumption system for data acquisition, transmission and control, can improve the reliability of operation, improves the transmission distance and anti-interference performance of signals, can solve the problem of interoperation among different electronic products, and can remarkably prolong the service life of a battery.

The connection relationship of the main circuits of the PW-01 type Bluetooth module is shown in FIG. 3, and a master-slave start terminal P01 of the PW-01 type Bluetooth module is connected with a power supply VCC; a recovery factory setting end P12 of the PW-01 type Bluetooth module is connected with an IO end of the main processor; a serial port sending end P03 of the PW-01 type Bluetooth module is connected with a serial port receiving end of the main processor, and a serial port receiving end P02 of the PW-01 type Bluetooth module is connected with the serial port sending end of the main processor; the sleep control end P20 of the PW-01 type Bluetooth module is connected with the IO end of the singlechip.

second, system operating principle

Working principle of Bluetooth module I

The main working process and principle of the bluetooth module can be summarized as follows: the main lamp terminal and the standby lamp terminal are automatically paired according to a preset rule after being powered on, and a data transparent transmission mode is entered to realize mutual control. The pairing procedure and rules are as follows:

1. When the Bluetooth module is powered on, the LPC1769 type single chip microcomputer controls an IO end (68 pin) of the single chip microcomputer to output a high level all the time, the pin is connected with a reset pin RST of the Bluetooth module, and the reset pin RST of the Bluetooth module is effective in a low level, so that the Bluetooth module is set to be normally started.

2. After the LPC1769 type single chip microcomputer sends an AT instruction, the Bluetooth module is awakened when the AT instruction reply of the Bluetooth module is required, and the Bluetooth module can be in a sleep state by being pulled up AT other times, so that the power consumption is reduced; because the pin 65 of the single chip microcomputer is connected with the sleep control end P20 of the PW-01 type Bluetooth module, when the LPC1769 type single chip microcomputer needs to obtain the return of the AT instruction of the Bluetooth module after sending the AT instruction, the single chip microcomputer should pull down the IO end (pin 65) of the single chip microcomputer, and the single chip microcomputer should pull up the IO end (pin 65) of the single chip microcomputer AT other times.

3. After power-on and before unpairing, the Bluetooth module of a single navigation light control terminal enters a host mode under the control of an LPC1769 processor, searches for a slave in 1000ms of time, and determines the equipment name and password connection. If the corresponding slave is not searched, the mode is immediately switched to the slave mode (the Bluetooth module waits for a random time duration of 5000ms to 8000ms in the slave mode). The Bluetooth module is repeatedly switched between a master mode with the time duration of 1000ms and a slave mode with the time duration of 5000ms to 8000ms at random until the connection to the slave or the connection by the master is successful (the Bluetooth module is designed in a master-slave mode).

4. after the pairing is successful, the master and the slave enter a data transparent transmission mode.

(II) working principle of power supply management module

As shown in fig. 1 and fig. 2, the BQ34Z100 type chip is a beacon light power management module, the BQ34Z100 type chip is the main component unit of the power management unit of the present invention, the positive terminal of the beacon light battery is connected to BAT terminal (4 pins) of the BQ34Z100 type chip through the peripheral device of the BQ34Z100 type chip, the negative terminal of the beacon light battery is connected to SRP terminal (9 pins) of the BQ34Z100 type chip through the peripheral device, and the SRP terminal (9 pins) is grounded through the capacitor; the 12 feet of the BQ34Z100 type chip are beacon light battery voltage detection feet and are connected with an IO end (25 feet) of a beacon light core control module LPC1769 type single chip microcomputer, therefore, the 25 feet of the LPC1769 type single chip microcomputer are under-voltage alarm identification ends, when the beacon light battery is under-voltage (voltage values are set through software customization), the 25 feet of the LPC1769 type single chip microcomputer identify the under-voltage alarm signals and then trigger internal instructions to output under-voltage alarm commands, and the under-voltage alarm commands are transmitted to a serial port receiving end P02 of the Bluetooth module by a serial port transmitting end (67 feet) of the LPC 1769.

(III) mutual control working principle between main lamp control system and standby lamp control system

obviously, the main lamp and the standby lamp each operate under the control of their control systems; the main lamp device and the standby lamp device are arranged in the same small area range of the navigation channel to provide guidance for the road wheels. Of course, it should be noted that: the control system of the main lamp and the standby lamp is a control system with completely identical circuit structure and working characteristics.

The main lamp device is insufficient along with the increase of the working time in the working process, and the unit management chip of the main lamp device sends out an under-voltage alarm signal, as can be known from the principle explained in the foregoing: the Bluetooth module of the main lamp control system receives the under-voltage alarm instruction of the main lamp control system and then transmits the under-voltage alarm instruction to the Bluetooth module of the standby lamp control system.

After receiving the activation instruction, the bluetooth module of the standby lamp control system transmits the activation instruction to a serial port receiving end (66 feet) of an LPC1769 type single-chip microcomputer through a serial port transmitting end P03 of the bluetooth module, then the internal instruction of the LPC1769 type single-chip microcomputer starts a lamp to work, the lamp works and then gives a lamp dormancy instruction to the main lamp control system through the bluetooth, and the internal instruction of the LPC1769 type single-chip microcomputer of the main lamp control system controls the main lamp to enter a dormancy period (namely, enters a state of being supplemented with electricity by a solar panel).

As is readily understood by those skilled in the art: when the standby lamp battery is under-voltage, an activating instruction is given to the main lamp through the Bluetooth, the main lamp starts to work, the Bluetooth of the main lamp gives a dormant instruction to the standby lamp, the two lamps can work circularly under two working states of starting and dormancy, and the beacon lamp in a small area range can work normally all the time to ensure the safety of the road wheel.

From the above analysis of the working principle, those skilled in the art can understand that the present invention has several significant features as follows:

1. The method adopts a double-lamp mutual backup and mutual control working mode, and autonomously negotiates and switches the master-slave relationship, and when one lamp works, the other lamp is standby. When a lamp is powered on to work, the lamp firstly inquires whether other matched lamp control systems exist around and matches the matched lamp control systems (the matching method is explained in detail in the Bluetooth module working principle and is not described herein any more), and if the matched lamp control systems exist and the lamp state is normal, the lamp enters a dormant state to be standby; if no matched lamp is found or the state of the matched lamp is abnormal, the matched lamp enters the working state immediately or informs the matched lamp control system that the matched lamp control system can enter the dormant state.

2. the lamp control system automatically detects the working state, and immediately informs the standby lamp to immediately enter the working state and the standby lamp to enter the dormant standby state once the lamp control system finds that the lamp control system cannot recover the self fault temporarily.

3. When the lamp finds self faults, if the channel to the platform is normal, the lamp sends an alarm to the platform, and if the channel to the platform is not communicated, the paired lamp is informed to start and send an alarm to the platform (the function needs the platform to be matched).

4. Due to the interactive mutual control instruction of the lamp control system, when the main lamp is under-voltage, the main lamp gives an activation instruction to the standby lamp to wake up the standby lamp to replace the main lamp to work, and the beacon lamp is ensured to be in an uninterrupted working mode all the time. The static power consumption of the Bluetooth is particularly small, and the value of uA is the value of 8.29mA in standby when the whole system works normally, so that the solar charging efficiency (in winter) can be played to the maximum when the lamp is in deep sleep.

5. The two lamps are automatically paired according to a preset rule without intervention of a platform or other tools.

(IV) mutual control intercommunication working mode

In addition, in fact, as shown in fig. 4, the utility model discloses still have multiple mutual control intercommunication working method:

1. Lamp-lamp mutual control

The working principle and procedure are as described hereinbefore.

2. mobile phone-lamp control

After the mobile phone and the lamp bluetooth are paired, the mobile phone can send an application execution instruction to the lamp bluetooth, for example: setting a Bluetooth master slave; restarting Bluetooth; waking up the lamp; the lamp is dormant; upgrading the system; reading certain key data of the lamp, etc.

3. platform-lamp control

the platform sends related execution instructions to the LPC1769 through GPRS, such as: setting a Bluetooth master slave; waking up the lamp; the lamp is dormant; restart bluetooth, etc.

(V) safety and security measures

1. The device name and the pairing password of the preset rule are used for pairing, for example, the slave machine generates the pairing password through an encryption algorithm by the local device name, the local MAC address and the secret key, when the master machine searches the slave machine, the device name and the MAC address of the slave machine can be obtained from the broadcast packet of the slave machine, and the same secret key is added to calculate the pairing password to complete pairing. And in the same way, the legal verification can be carried out through the device name which accords with the rule.

2. And when the pairing is successful and the transparent transmission mode is entered, the two parties communicate and transmit the service message through the ciphertext, and the other party needs to restore the source message after receiving the message through a decryption algorithm.

The utility model discloses an use new technique and the new application of writing in the navigation mark lamp system, make the navigation mark lamp maintenance system improve efficiency to the application development of new technique improves production efficiency, plays the effect that makes a lot of trouble is doubly to navigation mark lamp maintenance work. Especially at night, the recovery timeliness after the lamp failure is ensured.

therefore, the navigation light control system can change the traditional maintenance mode of the navigation light, improve the maintenance workload and the operation difficulty of front-line navigation channel workers, save the maintenance cost of the navigation channel and improve the maintenance work efficiency of the navigation channel.

the system is proved to be completely realized through production feasibility, the result shows that the system is novel in scheme and easy to implement, can solve some outstanding problems at present, and has remarkable intelligent function.

In addition, the main processor can be connected with an ADXL345 type inclination angle sensor to realize the inclination angle data acquisition of the beacon light and can be transmitted to the center of the platform through a GPRS network.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
