Computer or PLC or touch panel device signal connection, the main batching controller with it is multiple from batching controller
Connected between table by RS-485 communication signals, the main batching controller and multiple connect batch weigher respectively from batching controller
The difference in functionality element of weight system.This control system selects the batching controller with RS232/RS485 communication modules, will be multiple
Communicated by RS485 from the data of batching controller and be attached with main batching controller, then turned by main batching controller
Become RS232 communications to be connected with upper equipment, realize a RS232 communication by multichannel batching controller and upper device talk
Effect, each batching controller has a corresponding ID number in upper equipment, can accurately search each dispensing
The working condition of controller, and it is configured.And each batching controller selected is equipped with RS232/RS485
Communication module, therefore any one batching controller in the system can all be used as main batching controller, Mei Gepei
Material controller can individually connect upper equipment, therefore this control system can connect multiple upper equipment simultaneously.
Further, the batching controller also includes spacing/operation detection module, auxiliary reclay module, analog quantity
Signal acquisition module, the analog signalses acquisition module collecting temperature, weighing, current signal.Each function of batching controller
Module has corresponding connection socket, realizes and each item data of batching weighing system is monitored in real time.
Further, magnetic valve, the A.C. contactor of the auxiliary reclay module connection weighing system, controls electromagnetism
The switch motion of valve, A.C. contactor.Controlled by the switch motion of magnetic valve, A.C. contactor each in batching weighing system
The switch of the equipment such as individual regulating valve, motor, pump, complete dispensing work.
Further, the batching controller connects printer by RS-232 or R-S485 communication interfaces, described in printing
Every data message in the batching controller course of work.
Further, the batching controller connects d GPS locating module, positioning by RS-232 or RS-485 communication interfaces
The installation site of the batching controller.The position of each batching controller can accurately be found.
Compared with prior art, the utility model design batching weighing control system have it is following some：Realize first
Upper equipment is communicated with multiplexer (MUX by a RS232 communication, easy to operate, system is simpler；Furthermore
This control system can connect multiple upper equipment simultaneously, and can be realized in each upper equipment logical with all controllers
News；The functional module of last batching controller is various, is more widely applied.
