[0002] The existing RGV (rail-guided vehicle) trolley electronic control system is almost all integrated into the vehicle body. The vehicle design is compact, the electronic control system is relatively closed, the ventilation conditions are poor, and the in-vehicle environment detection equipment is missing. It mainly relies on high-margin fans and other equipment to continuously dissipate heat to maintain the internal electronic control environment, such as the heat dissipation device and AGV trolley with announcement number CN111935959B. It is impossible to perform real-time detection of the operating environment of the internal electronic control system of the RGV trolley. In addition, the RGV has a heavy load and a fast running speed. If a large vibration occurs during rail operation, manual maintenance is required. The current RGV trolley lacks vibration detection technology, which poses a safety hazard. The existing RGV trolley is also unable to conduct statistics, display, and review of historical data on the internal environment and operating vibration of the RGV trolley. Summary of the invention

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. Distributed independent sensor modules can disperse the detection of multi-point environmental data inside the vehicle body, making the detection more comprehensive and reliable; each sensor module communicates with the microcontroller controller using wireless data transparent transmission such as Bluetooth or WiFi, eliminating the need to arrange independent signal lines for each sensor module. The number and location of sensors can be configured more flexibly according to the actual internal structure of the RGV body.

[0012] 2. The detection data is stored in the cloud server, which reduces the resource usage of the core microcontroller, while also ensuring data security, increasing data storage space, and facilitating data calls by other peripheral devices.

[0013] 3. The real-time environmental status inside the RGV body automatically controls the start and stop of the environmental control equipment. Compared with traditional continuous heat dissipation equipment, it achieves precise control and is more energy-saving and environmentally friendly.

[0014] 4. The real-time vibration detection function during vehicle operation has been added, which can detect problems in time, carry out preventive maintenance in advance, and reduce safety hazards.

[0015] 5.

[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0025] Embodiment 2, a body condition maintenance system for RGV, the RGV body control PLC6 is connected to the WCS system, the WCS system is connected to the WMS system; the single-chip controller 5 is also connected to the cloud server through a wireless module, the cloud server is respectively connected to the WMS system and the mobile terminal dashboard, and the WMS system is connected to the on-site data dashboard; the several temperature and humidity sensors 1 are distributedly installed in the RGV control cabinet 7, and the several vibration sensors 2 are distributedly installed in the RGV control cabinet 7; the temperature and humidity sensor 1 and the vibration sensor 2 communicate with the single-chip controller 5 by wireless data transparent transmission, such as Bluetooth or WiFi; the single-chip controller 5 and the RGV body control PLC6 are connected by Modbus communication or serial port communication or CAN bus, and the rest is the same as Embodiment 1.

[0026] like Figure 3 As shown, the lower equipment layer mainly includes data acquisition sensors and environmental control equipment. The data acquisition sensors mainly include distributed temperature and humidity sensors 1 (such as Figure 4 As shown) and distributed vibration sensor 2 (as Figure 5 Each distributed sensor communicates with the single-chip controller by wireless data transmission such as Bluetooth or WiFi, and the number and location of distributed sensors can be more flexibly configured according to the actual layout in the cabinet. The environmental control equipment mainly includes a cooling air conditioner 3 and a dehumidifier 4, which respectively improve the temperature and humidity in the cabinet, and the single-chip controller 5 (such as Figure 6 As shown) directly sends out working status signals.

[0027] The core device of the middle control layer is the single-chip controller 5, which is internally provided with a two-level threshold protection mechanism. The single-chip controller 5 first receives multiple environmental data from the temperature and humidity sensor 1 and the vibration sensor 2. When any temperature data reaches the first-level threshold interval, the air conditioner is started to actively cool down; when the temperature drops below the first-level threshold after the active cooling is started, the air conditioner is automatically turned off; but when the temperature continues to rise to the second-level threshold, the single-chip microcomputer sends an alarm message to the RGV body control PLC6, the PLC control system shuts down and uploads the alarm to the WCS system and the WMS system. The humidity control logic in the RGV control cabinet 7 is the same as above. When any vibration sensor 2 data exceeds the safety threshold, it means that the RGV body has abnormal vibration and fails to meet the safety working requirements.

At the same time, when the environmental value in the RGV control cabinet 7 reaches the alarm threshold, the single-chip will synchronously upload the alarm information to the cloud server, and the cloud server will actively push the alarm information to mobile phones and other devices, prompting manual maintenance.
