Problems solved by technology

[0006] However, compared with the locker control system based on the centralized architecture, the disadvantage of the locker control system based on the distributed architecture is that the system structure is complex, the sub-controllers are highly correlated, the cost is relatively high, and maintenance is difficult.

Embodiment Construction

[0033] The present invention proposes a distributed locker control system, including a main controller, sub-controllers, execution and sensing components, each cabinet of the locker corresponds to a sub-controller and execution and sensing components, the main control The controller and the sub-controller, and the sub-controller and other sub-controllers are connected through communication lines, control lines and power lines respectively, and the sub-controllers are connected with the execution and sensing components of the corresponding cabinets.

[0034]In the above-mentioned communication lines, control lines and power supply lines, the communication lines include a RS485 communication bus and a UART serial communication bus, and the main controller is connected to each of the sub-controllers through the RS485 communication bus. The main controller and all the sub-controllers are connected in series through the UART serial communication bus; the control circuit includes a r...

Abstract

The invention relates to a control system and control method of a distributed storage cabinet. The control system comprises a master controller (10), auxiliary controllers (12a, 12b and 12n) connected with the master controller (10) through an RS485 communication bus in parallel, executing and sensing components in signal connection with the auxiliary controllers (12a, 12b and 12n) respectively and a system power supply circuit. The control system is characterized in that a parallel connection direct communication mode, a series connection relay communication mode and reset control signal lines exist between the master controller (10) and the auxiliary controllers (12a, 12b and 12n) and among the auxiliary controllers (12a, 12b and 12n) at the same time. By means of the control system and control method of the distributed storage cabinet, if one auxiliary controller gets into communication failure, the fault can be automatically judged immediately, and the function of the RS485 communication bus is recovered. If one auxiliary controller gets into other functional faults, front equipment of the auxiliary controller can find the faults in time, the auxiliary controller is restarted, and therefore the function of the auxiliary controller is recovered.

Description

technical field [0001] The invention relates to a distributed locker control system and a control method thereof, in particular to a distributed locker control system with self-organizing diagnosis and repair functions and a control method thereof. Background technique [0002] The locker control system can meet the needs of people to temporarily store personal items in public places, and because of its convenience, it has been widely used in government agencies, schools, libraries, leisure and entertainment places, large supermarkets and other public places in the past ten years. Wide range of applications. [0003] Traditional locker control systems can be divided into two types according to different architectures: locker control systems based on centralized architecture and locker control systems based on distributed architecture. [0004] Based on the locker control system of centralized architecture, the main controller directly connects the execution and sensing comp...
