Workshop monitoring alarm system based on CAN bus

Abstract

The invention discloses a workshop monitoring alarm system based on a CAN bus, which consists of a system monitoring host, a workshop controller and an office area alarm controller which are mutually connected through the CAN bus. The controller of each production workshop is provided with a keyboard entry, a buzzer and corresponding LED display lamps; and when the workshop has fault, a worker can press down corresponding error signal buttons, and the controller generates sound and light alarm and transmits signals to an office area and a central monitoring room through the CAN bus. The office area controller can receive the signals transmitted from the workshop, and the LED lamps display corresponding errors to prompt office workers. The central monitoring room is provided with a computer host, and the CAN bus receives and records various error signals transmitted from the field and displays the error signals on the LCD. The workshop monitoring alarm system has real-time and reliable communication capability, and good expansion capability of the system is suitable for the workshop monitoring alarm systems of various types and scales.

Description

technical field [0001] The invention relates to a new workshop monitoring and alarm system, especially adopts CAN field bus technology, distributed control mode realizes decentralized control and centralized management of each production workshop and office area, improves the reliability of the monitoring and alarm system, and realizes Intelligent control of workshop alarm. Background technique [0002] Driven by domestic and foreign markets to improve factory production efficiency and production safety, various monitoring and alarm systems in China are also emerging. But at present, most of China's monitoring and alarm systems can only realize point-to-point communication and rely on manual recording mode. The workshop monitoring and alarm system based on CAN bus is an automatic control system integrating a series of high and new technologies such as electronic technology, communication technology, computer technology and sensor technology. The centralized control system ...

AI Technical Summary

Problems solved by technology

The hardware and software required by the system with PLC as the core can be bought from the market, but the overall price is expensive and the wiring is more complicated

(3) Centralized workshop alarm monitoring system, all input and output functions are centrally controlled by the controller, once the controller fails, the entire system will be paralyzed
