[0030] According to the inventor's long-term research and development experience, the core function of the chassis controller used in road traffic scenarios is to detect the operating environment of the sensing facility, that is, the focus is on knowing the operating environment such as power supply, network supply, door switch status, etc. when the chassis is used, as well as remote load restart. To this end, this application provides a chassis controller based on AC power.

[0032] The input end of the mains power failure detection module 2 is electrically connected to the mains power, and the output end of the mains power failure detection module 2 is electrically connected to the input end of the central processing unit 1; the detection end of the electric energy sensor 3 is used to detect the mains power 9, and the output end of the electric energy sensor 3 is electrically connected to the input ends of the electric energy metering module 4 and the load power failure restart control module 5 respectively, and the output ends of the electric energy metering module 4 and the load power failure restart control module 5 are electrically connected to the input end of the central processing unit 1; the input end of the network detection module 6 is connected to the network communication, and the output end of the network detection module 6 is electrically connected to the input end of the central processing unit 1; the detection end of the box door status detection module 7 is used to detect the box door status, and the output end of the box door status detection module 7 is electrically connected to the input end of the central processing unit 1.

[0033] See also Figure 3 In this application, the central processing unit 1 adopts a processor of the STM32 series, and the preferred model is STM32F103RET6.

[0034] See also Figure 3 and Figure 4 In the present application, the electric energy metering module 4 includes an electric energy detection module and an optical coupler isolation module. The input end of the electric energy detection module is electrically connected to the mains 9, the output end of the electric energy detection module is electrically connected to the input end of the optical coupler isolation module, and the output end of the optical coupler isolation module is electrically connected to the input end of the central processor 1.

[0035] An AC-based chassis controller provided in the present application also includes a RC step-down module 8 and an optocoupler isolation module. The input end of the AC power failure detection module 2 is electrically connected to the AC power through the RC step-down module 8, the input end of the optocoupler isolation module is electrically connected to the output end of the RC step-down module 8, and the output end of the optocoupler isolation module is electrically connected to the input end of the AC power failure detection module 2.

[0036] See also Figure 3 and Figure 5In the present application, the network detection module 6 includes an Ethernet detection module and a mobile network detection module. The input end of the Ethernet detection module is connected to the Ethernet communication, and the output end of the Ethernet detection module is electrically connected to the input end of the central processor 1. The input end of the mobile network detection module 6 is connected to the mobile network communication, and the output end of the mobile network detection module is electrically connected to the input end of the central processor 1.

[0037] See also Figure 6 , Figure 7 and Figure 8 The present application provides an AC-based chassis controller, which is provided with an output socket 102 on the front panel of the chassis that can remotely control restart, a fuse socket 103 for protecting the input power supply, a probe of an ultrasonic detector 104 for detecting the state of the box door, a network port 105 for connecting the controller to the service, a positioning antenna interface 106 for Beidou and GPS positioning, a mobile communication interface 107, a communication expansion interface 108 for expanding RS485 communication, and a peripheral interface 109 for connecting peripheral devices.

[0038] The AC-based chassis controller provided in the present application ensures the collection and control of key points of the chassis, rather than seeking to collect more data items and more control functions. It only integrates key functional items such as power on and off, network on and off, door switch and remote control at one time, rather than seeking additional connections. For example, it eliminates the need to install an independent temperature and humidity sensor to realize data collection on temperature and humidity, and eliminates the need to install a micro switch to realize collection and judgment of the door status, etc.

[0039] This application comprehensively considers the simplification of assembly, avoiding the impact of self-assembly and secondary assembly on product quality. The input power socket 110 uses a C14 standard patch socket to avoid flying wire connections when assembling independent sockets; the ultrasonic detector 104 is delivered as an integrated chassis controller, avoiding the uncertainty of the chassis assembly (secondary assembly) quality caused by external micro switches, infrared rangefinders or ultrasonic rangefinders. This uncertainty mainly refers to the uncertainty of the division of labor interface and the uncertainty of post-assembly quality. The chassis sheet metal party is responsible for the quality of the sheet metal and assembly coordination, but has no way of knowing the quality of the assembly. Instead of doing this, it is better to let the chassis sheet metal party be responsible only for matters within its profession, rather than forcing non-professional matters on the sheet metal party.

[0040] In summary, the AC-based chassis controller provided in the present application simplifies assembly, improves assembly efficiency, reduces uncertainty in assembly quality and subsequent maintenance costs while ensuring the core functions of the intelligent chassis controller.

[0041] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
