[0001] This application relates to the field of on-vehicle equipment monitoring and control, and particularly to a monitoring and control system and method for on-vehicle equipment of a command communication vehicle based on a single-chip microcomputer. Background Art

[0002] A command communication vehicle is a mobile command platform formed by installing various special equipment such as communication, lifting, and power supply on a general vehicle. With the increase in functional requirements, the on-vehicle equipment is becoming increasingly numerous, and the management complexity has increased significantly. Currently, the mainstream solution relies on an on-vehicle industrial control computer to build a central control system. The industrial control computer has high power consumption and cannot work continuously in the vehicle parking or power-off state, making it difficult to achieve long-term unattended monitoring of the equipment status, and it is easy to cause hidden dangers such as battery discharge and cabin doors not closed that cannot be discovered in time. Therefore, there is an urgent need for a new type of monitoring and control system with a simple structure, low power consumption, high integration, and vehicle status linkage ability to achieve comprehensive perception, intelligent early warning, and remote control of on-vehicle equipment. Summary of the Invention

Efficient data interaction is achieved through a master-slave serial communication mechanism, which not only enhances the overall operational stability but also facilitates flexible expansion of I / O interfaces according to task requirements. The execution unit supports multi-level cascading and can adapt to different scales and types of vehicle-mounted equipment configurations. The control unit integrates a CAN bus interface, a GSM communication module, and Ethernet communication functions, enabling real-time synchronization of equipment status with the host computer during vehicle operation and proactive sending of abnormal alarms via the GSM communication module while parked, achieving unattended monitoring. Simultaneously, the system introduces an intelligent power management strategy: automatically cutting off power to the execution unit in the absence of abnormalities and putting the microcontroller into a low-power mode, significantly reducing standby power consumption and meeting the energy-saving requirements for long-term deployment of special vehicles. Furthermore, through the coordinated operation of the DI digital input module, the AI ​​analog input module, and the DO relay output module, the system can comprehensively sense and remotely control key parameters such as the boarding door, support legs, battery voltage, fluid level, temperature, and humidity, effectively avoiding safety hazards caused by equipment failure to reset or abnormal status.

The vehicle status includes parked and driving states. The monitoring system is a system composed of a control unit and an execution unit, used to monitor the status of the on-board equipment. The wake-up methods include timed wake-up and button wake-up. Button wake-up includes a vehicle start signal and a switch signal, wherein the switch signal is a manual button switch, which wakes up the system. When the vehicle is parked, the monitoring system is periodically woken up by the real-time clock built into the microcontroller at preset time intervals. After each timed wake-up, the monitoring system executes the equipment monitoring program. If the status of the on-board equipment is abnormal, it sends a warning message to the remote terminal through the GSM communication module and returns to standby mode. When the vehicle is in motion, the monitoring system is woken up by pressing a button. After being woken up, the monitoring system executes the equipment monitoring program. If the status of the on-board equipment is abnormal, it performs the corresponding operation based on the button wake-up signal and interacts with the host computer through network interruption to upload the status information of the vehicle and equipment.

[0012] In conjunction with the second aspect above, in one possible implementation, the button wake-up method is a vehicle start signal, including: If the monitoring system receives a vehicle start signal, it executes a device monitoring program to detect the status of the on-board equipment; it determines whether the on-board equipment has any abnormal status that affects driving safety; if so, it sends a warning message to a remote terminal via the GSM communication module and does not allow the vehicle to enter driving mode until the abnormal status is eliminated; otherwise, it allows the vehicle to enter driving mode; wherein, the remote terminal includes an in-vehicle display screen and an alarm.

[0018] This application provides a microcontroller-based monitoring and control system and method for onboard equipment in command and communication vehicles. The microcontroller-based hardware system and intelligent control method are organically combined to form a highly efficient, reliable, and low-power solution for monitoring and controlling onboard equipment in command and communication vehicles.

Detailed Implementation

[0021] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] The microcontroller-based monitoring and control method for onboard equipment of a command and communication vehicle provided in this application can be applied to, for example... Figure 1 In the microcontroller-based vehicle-mounted equipment monitoring and control system 100 shown, such as Figure 1 As shown, the system includes: a control unit 1 and an execution unit 2; The control unit 1 includes a microcontroller 11, which is connected to an input module 12, a network communication module 13, an output module 14, a GSM communication module 15, a serial port communication module 16, and a power control module 17. The input unit 12 of the control unit 1 is used to connect to the vehicle CAN bus to obtain vehicle operating status information, the output module 14 is used to connect to the in-vehicle display screen and alarm, the network communication module 13 is used to connect to the host computer for data interaction, and the GSM communication module 15 is used to send alarm information to the remote terminal and remotely prompt the system for abnormal conditions when the vehicle is parked.

[0023] Execution unit 2 includes a DMA relay controller 21, which is connected to a DI digital input module 22, a serial port 2 communication module 23, a power supply module 24, an AI analog input module 25, and a DO relay output module 26. Among them, the DI digital input module 25 of the execution unit 2 is used to connect to the limit switch and to detect the reset status of the vehicle equipment; the AI ​​analog input module 25 is used to collect vehicle status data; and the DO relay output module 26 is used to connect to the power control terminal of the vehicle equipment for remote power on / off control. The vehicle status data includes oil level, liquid level, temperature, and humidity.

[0024] Furthermore, the serial communication between the control unit 1 and the execution unit 2 adopts a master-slave architecture, where the control unit 1 initiates a communication request, and the execution unit responds and returns the acquired data or executes control commands; the power control module 14 is controlled by the microcontroller 11 and is used to manage the power supply status of the execution unit 1.

[0025] The serial port communication module 16 of the control unit 1 is connected to the serial port communication module 2 of the execution unit 2 via a serial bus, and is used to upload collected data and receive control commands; the power control module 17 of the control unit 1 is electrically connected to the power module 24 of the execution unit 2, and is used to dynamically control the power supply of the execution unit 2 by the control unit 1 to achieve low-energy operation of the system.

[0026] It should be noted that the DMA relay controller 21 supports multiple unit cascading expansions to increase the number of interfaces of the DI digital input module 22, the AI ​​analog input module 25, and the DO relay output module 26.

[0027] After the monitoring device enters the working mode, the control unit 1 establishes a connection with the host computer through the network communication module 13, and uses the network interrupt procedure mechanism to upload the real-time collected vehicle device status information and vehicle status information to the host computer, while receiving and executing the device control commands issued by the host computer.

[0028] Based on the above technical solution, a distributed architecture with separate control unit 1 and execution unit 2 is adopted. High-efficiency collaboration is achieved through master-slave serial communication, which improves system reliability and facilitates functional expansion. Execution unit 2 supports multi-level cascading, flexibly adapting to different vehicle models and equipment configuration requirements. Control unit 1 integrates CAN bus access, GSM remote alarm, and Ethernet communication capabilities, enabling real-time data interaction with the host computer. Even during parking, it can proactively push abnormal information via GSM communication module 15, ensuring 24 / 7 safety monitoring. The monitoring system features an intelligent power management mechanism, dynamically cutting off power to execution unit 2 from control unit 1 and putting the microcontroller into a low-power mode, significantly reducing static energy consumption, making it particularly suitable for special vehicles with long service life. Furthermore, the DI digital input module 22, AI analog input module 25, and DO relay output module 26 comprehensively cover limit status, environmental parameters, and equipment power control, achieving integrated monitoring and remote control of key elements such as the access door, support legs, and hydraulic / electrical systems, effectively preventing safety accidents caused by equipment failure to reset or abnormal status. The overall solution has a clear structure, complete functions, low power consumption, and strong scalability, which significantly improves the intelligent operation and maintenance level and mission support capability of the command and communication vehicle.

[0029] like Figure 2 As shown, the second aspect of the present invention provides a method for monitoring and controlling on-board equipment of a command and communication vehicle based on a microcontroller, comprising the following steps: When the monitoring system is in standby mode, it is woken up by a corresponding wake-up method based on the vehicle status. The vehicle status includes parked and driving states. The monitoring system is a system composed of a control unit 1 and an execution unit 2, used to monitor the status of the on-board equipment. The wake-up methods include timed wake-up and button wake-up. Button wake-up includes a vehicle start signal and a switch signal, wherein the switch signal is a manual button switch, which wakes up the system. When the vehicle is parked, the monitoring system is periodically woken up by the real-time clock built into the microcontroller 11 at preset time intervals. After each timed wake-up, the monitoring system executes the equipment monitoring program. If the status of the on-board equipment is abnormal, it sends a warning message to the remote terminal through the GSM communication module 15 and returns to standby mode. When the vehicle is in motion, the monitoring system is woken up by pressing a button. After being woken up, the monitoring system executes the equipment monitoring program. If the status of the on-board equipment is abnormal, it performs the corresponding operation based on the button wake-up signal and interacts with the host computer through network interruption to upload the status information of the vehicle and equipment.

[0030] Among them, such as Figure 3 As shown, the equipment monitoring procedure flow is as follows: After the monitoring system is awakened, the power control module 14 of the control unit 1 supplies power to the execution unit 1, thereby establishing a serial communication connection between the control unit 1 and the execution unit 2. The control unit collects data from different sensors through the AI ​​analog input module 25 of the execution unit, covering various parameters such as battery power, fuel tank level, and ambient temperature and humidity. In addition, the control unit uses the DI digital input module 22 of the execution unit to detect the status of various limit switches to determine whether the relevant equipment has been correctly reset. The control unit 1 saves the data obtained from the execution unit 2 into memory variables, packages it, and sends it to the host computer through the network communication module 13.

[0031] It should be noted that during the long-term parking of the command and communication vehicle, the monitoring system can periodically and autonomously monitor the status of the on-board equipment and take automatic measures based on the monitoring results, thereby achieving continuous monitoring of the command and communication vehicle equipment.

[0032] In addition, the monitoring system can also be activated by pressing a button in standby mode; button activation methods include vehicle start signal and power switch signal. When the button wake-up method is the vehicle start signal, if the monitoring system receives the vehicle start signal, the monitoring system executes the device monitoring program to detect the status of the vehicle-mounted equipment; determines whether the vehicle-mounted equipment has an abnormal status that affects driving safety; if yes, it sends a warning message to the remote terminal through the GSM communication module 15 and does not allow the vehicle to enter the driving state until the abnormal status is eliminated; otherwise, it allows the vehicle to enter the driving state.

[0033] When the button wake-up method is a switch signal, if the monitoring system receives the switch signal, it establishes communication with the host computer through the network interrupt program and uploads the status information of the vehicle equipment to the host computer; if the monitoring system receives the switch signal again, it terminates the current monitoring process, closes the device monitoring program, and enters standby mode.

[0034] Among them, such as Figure 4 The flow of the network interrupt procedure is shown below: When the network communication module 13 receives the control command data packet from the host computer, the microcontroller 11 parses the control command data packet. Based on the parsing result, the control unit 1 sends the corresponding control command to the serial port communication module 23 of the execution unit 2 through the serial port communication module 16. If the control command is the output command of the DO relay output module 26, the power supply of the relay output module 26 is turned on or off. If the control command is a query command, the device monitoring program is called to return data. If it is a special command (such as system restart), the corresponding operation is executed. After execution, the system generates an execution result feedback message, such as "success" or "failure", and sends the control command back to the host computer through the network communication module 13 to realize closed-loop control. After the feedback is sent, the program exits and waits for the next command.

[0035] like Figure 5 The procedure for shutting down the device monitoring program is as follows: The monitoring system is activated by a button or external signal. At this time, the system is in working condition and needs to be shut down in an orderly manner.

[0036] The system determines whether the shutdown request originates from a host computer, such as a remote dispatch platform. If not, it outputs the message "Please shut down the host computer first" and terminates the current process to prevent unauthorized shutdown. If yes, it shuts down the AC output / input contactors and the DC output / input contactors. Shutting down the AC output contactors disconnects the power to AC loads (such as lights and air conditioners); shutting down the DC output contactors disconnects the power to DC devices (such as radios, pan-tilt units, and tripping mechanisms); shutting down the AC input contactors disconnects the mains power or generator power; and shutting down the DC input contactors disconnects the battery or other DC power input. Control unit 1, through power control module 17, cuts off the power supply to execution unit 2, causing it to completely stop working. Simultaneously, microcontroller 11 enters low-power mode, retaining only basic wake-up functionality. With all power and loads now off, the system completes the safe shutdown process and finally enters low-power standby mode. In this mode, the system can be woken up periodically or restarted by pressing a button.

[0037] Based on the above technical solutions, a microcontroller-based method for monitoring and controlling onboard equipment in command and communication vehicles is provided. With its high efficiency, flexibility, and intelligent management, it demonstrates significant advantages in the field of special vehicle operation and maintenance. First, after power-on initialization, the system can quickly perform a comprehensive status check on the onboard equipment, ensuring that it automatically enters standby mode after normal operation. It enters a low-power state by cutting off the power supply to execution unit 2 and shutting down the power supply to peripherals, greatly reducing energy consumption, making it particularly suitable for command and communication vehicles parked for extended periods. Second, the system supports both timed wake-up and button wake-up, ensuring timely response under any circumstances. Whether it's a periodic check or an emergency start, it can immediately begin work and complete equipment status assessment, improving system response speed and reliability. Furthermore, by integrating the GSM communication module 15, it can promptly send early warning information to the superior terminal when an anomaly is detected, realizing remote monitoring and fault early warning, effectively avoiding the risk of task interruption due to equipment failure. The application of the AI ​​analog input module 25 and the DI digital input module 22 enables the monitoring system to accurately collect environmental parameters and limit switch status, providing solid data support for the safe operation of the onboard equipment. Of particular note is that this method employs a network interrupt procedure mechanism to achieve real-time data uploading and command reception, ensuring efficient and stable information exchange between the host computer and the vehicle-mounted equipment. Overall, this not only improves the automation management level of the command and communication vehicle but also significantly enhances its adaptability and survivability in complex environments, which is of great significance for improving the mission execution efficiency and safety of special vehicles.

[0038] like Figure 6 As shown, the third aspect of the present invention provides a product form of a microcontroller-based vehicle-mounted equipment monitoring and control system for command and communication vehicles; wherein, the front of the product includes an information display screen 31, a system indicator light 32, a system switch button 33, and a buzzer 34; the back of the product includes a network interface 35, a serial port 36, a control interface 37, and a power interface 38. Among them, serial port 36 includes serial port-1, serial port-2 and serial port-3; control interface 37 includes control-1 and control-2; system indicator 32 includes system power indicator, module power indicator and working status indicator.
