A single warehouse intelligent control terminal

Abstract

The invention discloses an intelligent single-bin control terminal which comprises an ARM master control module, a CAN bus chip, a switching power supply interface circuit, a grain condition detecting interface circuit, an inner loop current detecting interface circuit, an energy consumption detecting interface circuit, an insect pest gas detecting control circuit, an intelligent ventilation control circuit, a remote illumination control circuit and a switch. The CAN bus chip, the switching power supply interface circuit, the grain condition detecting interface circuit, the inner loop current detecting interface circuit, the energy consumption detecting interface circuit, the insect pest gas detecting control circuit, the intelligent ventilation control circuit, the remote illumination control circuit and the switch are respectively connected with the ARM master control module. The problem that existing various monitoring and execution devices in the grain storage industry are independently installed and cannot be centrally supervised and controlled is solved. Integrated control and supervision of all the grain condition monitoring devices of a warehouse are achieved, a CAN bus is adopted between the modules and the ARM master control module, the data share problem caused by non-unified interfaces is avoided, and data transmission and remote centralized control can be achieved.

Description

technical field [0001] The invention is applied to the field of comprehensive management of granaries in the grain industry, in particular to an intelligent control terminal for a single silo. Background technique [0002] The data interface of the grain condition detection module that provides real-time temperature and humidity information in the granary adopts the TTL interface, and the data transmission adopts the free protocol; completes the grain temperature control in summer, insecticide, and prevention of grain dew condensation in the spring and autumn. The module data interface adopts the RS232 interface, and the data transmission adopts the free protocol; the data interface of the intelligent energy consumption monitoring module, which monitors the power consumption of each electrical line to obtain the energy consumption of the equipment operation, adopts the RS485 interface, and the data transmission adopts the modbus communication protocol; real-time monitoring T...

Problems solved by technology

When the wireless communication function cannot be realized normally, the upper computer will not be able to collect the operating data of each module and remotely control each module. In addition, due to the inconsistency of the data interface of each module, each module is set separately, and it is difficult to integrate into a unified display control terminal. , it is impossible to realize the overall integration and related control, and it is impossible to grasp the grain situation of the warehouse as a whole, and it is only through personnel to carry out various statistics and operations
