Description

Technical Field

[0001] The present invention relates to an automatic wake-up control device, belonging to the technical field of special vehicle-mounted radar equipment manufacturing. Background Art

[0002] To meet the requirements of efficient and rapid war preparation in modern warfare, the combat readiness mobility performance of special vehicle-mounted radar equipment has received increasing attention. For special vehicle-mounted radar equipment to transition from a mobile state to a deployed state or from a deployed state to a mobile state, a series of actions are required, including power-on or power-off of each subsystem, vehicle body leveling or resetting, antenna array deployment or retraction, lifting and erection or lowering and folding, and azimuth lock pin unlocking or locking. Although the above-mentioned individual actions of existing special vehicle-mounted radar equipment have each achieved automatic functions, all the associated steps between these individual actions still need to be completed through manual intervention, which is inconvenient to operate, prone to errors, delays the rapid operation time from the mobile state to the deployed state or from the deployed state to the mobile state, and it is difficult to meet the high mobility requirements of vehicle-mounted radar equipment in modern warfare. Therefore, it is highly necessary to develop an automatic wake-up control device that can safely and efficiently automate all the associated steps between the individual actions of vehicle-mounted radar equipment, and can monitor the working status of each subsystem of the vehicle-mounted radar equipment in real time to ensure its stable, reliable, and smooth completion of a series of operations. Summary of the Invention

[0003] The purpose of the present invention is to provide, in view of the deficiencies of the above-mentioned existing technologies, an automatic wake-up control device that enables a vehicle-mounted radar equipment to be powered on under the control of the automatic wake-up control device when in an initial unpowered state; realizes real-time monitoring and error correction of all the associated steps between the individual actions, automatically and reliably controls and operates all the associated steps between the individual actions, is convenient to operate, avoids errors, effectively shortens the operation time, and greatly improves the high mobility performance of the vehicle-mounted radar equipment, so as to solve the problems of inconvenient operation, high error rate, and long operation time caused by manual intervention in all the associated steps between the individual actions of existing special vehicle-mounted radar equipment.

[0004] The present invention achieves the above-mentioned invention purpose through the following technical solutions: An automatic wake-up control device, comprising a housing and a UPS battery pack. An automatic wake-up control board, a power supply chip and other on-board peripheral hardware are installed inside the housing, and a DB25-SL connector and a D-SUB-37 connector are installed outside the housing. Its characteristics are as follows: The automatic wake-up control board mainly consists of an MCU chip, a power supply chip, a JTAG downloader, an RS422 transceiver, an RS485 transceiver, a CAN transceiver, an eight-channel signal transceiver, a four-bit DIP switch, an 8MHz crystal oscillator and a reset button. Through the MCU chip supporting the IDE integrated development environment, the code developed by the IDE integrated development environment is solidified into the FLASH inside the MCU chip through the JTAG downloader, and at the same time, online debugging is realized. An external high-speed 8MHz crystal oscillator is configured for the MCU chip to provide a stable clock base frequency for the MCU chip. The PLL frequency multiplication and frequency division factors are configured through the IDE software inside the MCU chip to keep the working frequency of the MCU chip at 168MHz. The output end of the UPS battery pack is connected to the input end of the power supply chip via the D-SUB-37 connector to provide DC24V excitation for the power supply chip. The USART full-duplex general synchronous / asynchronous serial transceiver module and the UART serial communication interface set inside and outside the MCU chip obtain the status information of the key subsystems of the vehicle-mounted radar equipment through the RS422 transceiver. The status information of the key subsystems of the vehicle-mounted radar equipment includes: the status information of the vehicle's power distribution system, the status information of the UPS battery pack, the status information of the power take-off control combination, and the status information of the power supply vehicle. The RS422 transceiver communicates with the master control via a serial server, receives the control commands of the master control and uploads the status information. The RS422 transceiver communicates with the radio via a serial server and receives the control commands of the radio. The CAN bus set inside and outside the MCU chip obtains the power and body attitude information of the vehicle chassis through the CAN transceiver. The D-SUB-37 connector collects the CAN bus differential level signals of the above information and converts them into CAN controller logic level signals through each CAN transceiver and transmits them to the MCU chip. The MCU chip outputs TTL level signals through the eight-channel signal transceiver to control the opening / closing of the relay and receives and judges the level signals, and knows whether the external button is pressed through the judged level signals. The MCU chip controls its own startup method through the four-bit DIP switch. The automatic wake-up control board realizes manual reset through the reset button, and the IDE software comes with a watchdog module, which can quickly perform a soft reset if the program runs away inexplicably, ensuring the normal operation of the automatic wake-up control device.

[0005] There are two MCU chips, with the model number GD32F407VET6, which integrate on-chip FLASH and RAM inside. The IDE matching the MCU chips is Keil5 MDK, version: 5.28. It mainly implements the reception and acquisition of various data frames, data caching, the packaging and sending of control command frames, and the input judgment and output control of multiple channel level states.

[0006] The model number of the RS422 transceiver is MAX3077EESA, which has fail-safe protection and supports hot plugging function. The RS422 transceiver is in the form of RS-422 level. One pair of its inputs obtains the status information of the key subsystems of the vehicle-mounted radar equipment via a D-SUB-37 connector, and one pair of its outputs sends control commands to the corresponding subsystems via a D-SUB-37 connector.

[0007] The power supply chip includes two types of high-efficiency linear voltage regulator chips. The power supply chip with the model number L7805CV provides a DC5V working voltage, and the UPS battery pack provides a DC24V input excitation for it. The power supply chip with the model number CW29150-3.3 provides a 3.3V working voltage, and the L7805CV chip provides a DC5V input excitation for it.

[0008] The 8MHz crystal oscillator selects a low-noise passive high-stability crystal oscillator.

[0009] The four-bit DIP switch provides startup modes for the two MCU chips of the automatic wake-up control board respectively; bit 1 and bit 2 of the four-bit DIP switch correspond to BOOT0 and BOOT1 of the first MCU chip, and bit 3 and bit 4 correspond to BOOT0 and BOOT1 of the second MCU chip. When both are set to "0", both MCU chips load the program from their respective on-chip FLASH when powered on.

[0010] The power take-off control combination refers to the power generation equipment.

[0011] The beneficial effects of the present invention compared with the prior art are: The automatic wake-up control device is independently powered by an automatic wake-up control board and a UPS battery pack, enabling the vehicle-mounted radar equipment to automatically wake up the control device to control power-on in the initial unpowered state. Through the MCU chip, RS422 transceiver, RS485 transceiver, and CAN transceiver of the automatic wake-up control board, real-time monitoring of the key subsystems of the vehicle-mounted radar equipment is achieved, and a series of actions such as power-on or power-off of each subsystem of the whole vehicle, body leveling or resetting, antenna array deployment or retraction, lifting erection or lowering folding, azimuth lock pin unlocking or locking are realized; a JTAG downloader is set to achieve convenient program update, parameter adjustment, and online debugging functions, with flexible operation, saving time and effort. A reset button and an IDE software watchdog module are set to ensure quick reset when the program encounters inexplicable accidents, and effectively ensure the stable, efficient, and safe operation of the automatic wake-up control device. It solves the problem that the series of steps of the existing special vehicle-mounted radar equipment from the mobile state to the deployment state or from the deployment state to the mobile state still need to be completed manually, with inconvenient operation, inevitable mistakes, and inability to meet the high mobility requirements of vehicle-mounted radar equipment in modern warfare.

[0015] MCU chip 7 mainly implements the reception and collection of various data frames, data caching, packaging and sending of control command frames, and input judgment and output control of multiple level states; MCU chip 7 adopts the product of Beijing Zhaoyi Innovation, model GD32F407VET6, which has integrated 512KB FLASH and 196KB RAM inside the chip. MCU chip 7 uses the supporting IDE: Keil5 MDK, version: 5.28. The IDE solidifies the developed code into the FLASH in the MCU chip through the JTAG downloader 6, and realizes online debugging at the same time.

[0016] The MCU chip 7 is equipped with an external high-speed 8MHz crystal oscillator 13. A low-noise passive high-stability crystal oscillator is selected. The 8MHz crystal oscillator 13 provides a stable clock base frequency for the MCU chip 7. The IDE software configures the phase-locked loop multiplication and division factors in the MCU chip 7 to keep the operating frequency of the MCU chip 7 at 168MHz.

[0017] The MCU chip 7 is provided with USART / UART inside and outside. USART is a full-duplex universal synchronous / asynchronous serial transceiver module, and UART is a serial communication interface. USART / UART obtains the key subsystem status information of the vehicle-mounted radar equipment through the RS422 transceiver 8, including: the status information of the vehicle power distribution system, the status information of the UPS battery pack, the power take-off control combination status information and the power supply vehicle status information; the D-SUB-37 connector 5 collects the physical differential level signals of the key subsystem status information of the above-mentioned vehicle-mounted radar equipment and converts them into continuous TTL logic level signals through each RS422 transceiver 8 and transmits them to the MCU chip 7.

[0018] The USART / UART set inside and outside the MCU chip 7 communicates with the main control through the RS422 transceiver 8 via the serial port server, including receiving the control command of the main control and uploading status information; the USART / UART set inside and outside the MCU chip 7 communicates with the radio station through the RS422 transceiver 8 via the serial port server to receive the control command of the radio station.

[0019] A CAN bus is provided inside and outside the MCU chip 7. The CAN bus obtains the chassis power and body posture information of the vehicle through the CAN transceiver 10. The D-SUB-37 connector 5 collects the CAN bus differential level signals of the above information and converts them into CAN controller logic level signals through each CAN transceiver 10 and transmits them to the MCU chip 7; the MCU chip 7 outputs a TTL level signal to control the opening / closing of the relay through an eight-way signal transceiver 11 of model 74HC245, and receives a judgment level signal at the same time, thereby knowing whether the external button is pressed or not; the MCU chip 7 controls its own startup mode through a four-position dial switch 12, and the four-position dial switch 12 provides startup modes for the two MCU chips 7 of the automatic wake-up control board 2, wherein bits 1 and 2 correspond to BOOT0 and BOOT1 of the first MCU chip 7, and bits 3 and 4 correspond to BOOT0 and BOOT1 of the second MCU chip 7. When both are dialed to "0", the two MCU chips 7 start the program from their respective corresponding on-chip FLASH as soon as they are powered on.

[0020] The automatic wake-up control board 2 is provided with a reset button 14, which can be used to manually reset the system. The IDE software has a built-in watchdog module, which can quickly perform a soft reset if the program runs away inexplicably, thereby ensuring the normal operation of the automatic wake-up control device. The power chip 3 includes two high-efficiency linear voltage regulator chip models. The power chip 3 with model L7805CV provides a DC5V operating voltage, and the UPS battery pack provides a DC24V input excitation for it; the power chip 3 with model CW29150-3.3 provides a 3.3V operating voltage, and the power chip 3 with model L7805CV provides a DC5V input excitation for it.

[0021] The functions of the automatic wake-up control device to collect key subsystem status information are briefly described as follows: (See Figure 2 ) as attached Figure 2As shown in the figure, the automatic wake-up control device needs to collect the status information of the vehicle power distribution system of the vehicle-mounted radar equipment (this status information is sent by the power distribution control box), the status information of the power take-off control combination, the status information of the power supply vehicle, and the status information of the UPS battery pack. The above subsystems all use the RS-422 level standard serial communication. After the physical differential level signals of the above status information are collected by the D-SUB-37 connector 5, they are converted into continuous TTL logic level signals by each RS422 transceiver 8 and transmitted to the MCU chip 7. At the same time, the automatic wake-up control device collects the vehicle chassis power and chassis body attitude information of the vehicle-mounted radar equipment. The above chassis information all uses CAN communication. After the CAN bus differential level signals of the above information are collected by the D-SUB-37 connector 5, they are converted into CAN controller logic level signals by each CAN transceiver 10 and transmitted to the MCU chip 7.

[0022] A brief description of the dual-machine communication function of the automatic wake-up control board 2 is as follows: The automatic wake-up control board 2 adopts a design of combining two MCU chips 7 (see Figure 2 ) As shown in the appendix Figure 2 As shown, the communication method from MCU_1 to MCU_2 adopts SPI communication, and the communication method from MCU_2 to MCU_1 adopts serial communication with the RS-485 level standard. Information sharing is achieved between the two MCU chips 7.

[0023] A brief description of the working process of the automatic wake-up control device is as follows: During operation, the UPS battery pack supplies power to the power supply chip 3, and the power supply chip 3 provides working voltage for each component of the automatic wake-up control board 2. When the IDE software program is burned into the on-chip Flash of the MCU chip 7 through JTAG and the startup mode is set: BOOT0 = 0, BOOT1 = 0, the machine starts up and loads the program from the Flash and runs. After starting up and running, the MCU chip 7 of the automatic wake-up control board 2 continuously obtains the status information of each key subsystem of the vehicle-mounted radar equipment through various serial ports and CAN interfaces and analyzes it. (See Figure 3(a) and Figure 3(b)). As shown in Figure 3(a) and Figure 3(b), the IDE software working process of the automatic wake-up control device mainly includes two threads, namely "one-key wake-up erection" and "one-key withdrawal and power-off". The trigger conditions of the two are different. "One-key wake-up erection" is triggered by pressing a button or receiving a radio command, and "one-key withdrawal and power-off" is triggered by pressing a button or receiving a main control command.

[0024] When the "One-key Wake-up and Erection" process is triggered, the automatic wake-up control device can know whether the power vehicle and the power take-off control combination are online by obtaining the status of each subsystem. If they are not online, they will be woken up. The wake-up mechanism is as follows: The GPIO of the MCU chip 7 outputs high and low levels, and the eight-way signal transceiver 11 of the model 74HC245 is used to control the opening / closing of the relay, thereby realizing the output / disconnection of the 24V electrical signal. The output of the 24V electrical signal is for waking up, and the disconnection of the 24V electrical signal is for shutting down the wake-up. After waking up, following the principle that whoever is woken up will supply power to the whole vehicle, first judge whether the power vehicle is online and close the corresponding contactor. The mechanism of closing / opening the contactor is the same as that of waking up. After closing, the vehicle power distribution system has input excitation. In the case of no power in the whole vehicle, send a control command to the power distribution control box to perform one-key power-on for the whole vehicle. After the power-on is successful, in the case where the whole vehicle is not leveled and erected in place, send a control command to the hydraulic leveling combination, which is forwarded by the power distribution control box, to perform the one-key leveling and erection process for the whole vehicle. After the leveling and erection are in place, following the principle that whoever supplies power to the whole vehicle will reset its corresponding contactor, reset the corresponding contactor. After resetting, the "One-key Wake-up and Erection" process ends (see Figure 3(a)).

[0025] The "One-key Dismantle and Power-off" process is the reverse process of the "One-key Wake-up and Erection" process. The specific software working process is shown in Figure 3(b).

[0026] An automatic wake-up control device realizes the switching of the vehicle-mounted radar equipment from the mobile state to the deployment state through the "One-key Wake-up and Erection" process; realizes the switching of the vehicle-mounted radar equipment from the deployment state to the mobile state through the "One-key Dismantle and Power-off" process; sets up an independent power supply of the UPS battery pack to enable the vehicle-mounted radar equipment to realize power-on controlled by the automatic wake-up control device in the initial non-powered state; realizes the real-time monitoring of the key subsystems of the vehicle-mounted radar equipment through the MCU chip 7, RS422 transceiver 8, RS485 transceiver 9, and CAN transceiver 10 of the automatic wake-up control board 2. When switching from the mobile state to the deployment state, control a series of actions such as power-on of each subsystem of the whole vehicle, body leveling, antenna array deployment, lifting and erection, and azimuth lock pin unlocking; when switching from the deployment state to the mobile state, control a series of actions such as power-off of each subsystem of the whole vehicle, body reset, antenna array retraction, lowering and folding, and locking the azimuth lock pin; set up a JTAG downloader 6 to realize the functions of convenient program update, parameter adjustment, and online debugging, with flexible operation, saving time and effort; set up a reset button 14 and a software watchdog module to ensure quick reset when the program has inexplicable accidents, further improving the reliability of the IDE software. It solves the problem that a series of steps for the existing special vehicle-mounted radar equipment to switch from the mobile state to the deployment state or from the deployment state to the mobile state need to be completed manually, with inconvenient operation, inevitable mistakes, and inability to meet the high mobility requirements of modern warfare for vehicle-mounted radar equipment.
