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
The present invention relates to a kind of new Workshop monitoring alarm system, particularly adopted the CAN field bus technique, distributed control model realizes the decentralised control and the centralized management of each workshop and Office Area, has improved the reliability of monitoring and alarming system, realizes the Based Intelligent Control of reporting to the police in the workshop.
Background technology
At home and abroad market is under the promotion that improves plant produced efficient and production safety, and Chinese all kinds of monitoring and alarming systems also constantly emerge in large numbers.The monitoring and alarming system major part of China can only realize the pattern of point-to-point communication and dependence manual record at present.Workshop monitoring alarm system based on the CAN bus is that a series of new and high technologies such as the sub-technology of current collection, mechanics of communication, computer technology and sensor technology are in the automatic control system of one.This centralized control system can receive all on-the-spot rub-out signal inputs, and by the remote monitoring of computer realization to all workshops, makes whole workshop appliance operate in optimum condition, can also reduce operating personnel's labour intensity greatly.
Modern times, the Workshop monitoring system was of a great variety, and the structure of control system is different.As (1) relay control system, this system adopts the rub-out signal in relay switch notice supervisory system workshop, and control method is simple, but because counting of workshop is more, wiring is got up cumbersome.(2) based on the point-to-point control system of PLC, the control system of forming by PLC, various input signal and output alarm based on the monitoring and alarming system of PLC.Be that hardware and the software that the system of core needs can both have been bought from market with PLC, but the average price costliness, and wiring is comparatively complicated.(3) centralized workshop alarm monitoring system, all inputs, output function will make the total system paralysis all by the controller centralized control in case controller breaks down.
Summary of the invention
Purpose of the present invention is intended to solve the problems of the technologies described above the deficiency of existence, and the Workshop monitoring alarm system that a kind of cost is low, function is strong, reliability is high is provided, and is made up of system monitoring main frame, Shop Floor Controller, Office Area alarm controller.Each workshop all is provided with a controller, and controller is provided with keyboard input, hummer and corresponding LED display lamp; The Office Area controller can be accepted the signal that the workshop is transmitted, and shows corresponding error by the LED lamp, and drives hummer prompting clerical workforce; Central control room is provided with a host computer, can accept and the on-the-spot various rub-out signals that transmit of record by the CAN fieldbus, can inquire about real-time rub-out signal in LCD display, and historical rub-out signal.Each Shop Floor Controller all is connected with Administrative Area by the CAN bus, and carries out data communication by CAN bus and system monitoring main frame.
The present invention, described Shop Floor Controller comprises microcontroller, online programming interface, digital quantity input module, digital quantity output module and CAN bus communication interface.
Microcontroller in the Shop Floor Controller adopts the PIC 16F system single-chip microcomputer of MICROCHIP, digital quantity input module has been realized the 6*6 input of totally 36 keyboards, by keyboard control chip ZLG7290 each button is discerned, microcontroller just can identify different buttons to finish function corresponding like this; The digital quantity output module has been realized the function of corresponding rub-out signal pilot lamp, and one has 36 pilot lamp, realizes control by ZLG7290, and the digital quantity output module has also been realized the function of control hummer in addition.CAN bus communication interface has then been realized and the communication of Office Area controller, middle watch-dog by bus transmitting-receiving driver module CTM1050, has been transmitted the corresponding error signal.
The present invention, described Office Area controller comprises microcontroller, online programming interface, digital quantity input module, digital quantity output module and CAN bus communication interface.
Microcontroller in the controller of Office Area adopts the PIC 16F system single-chip microcomputer of MICROCHIP, function that digital quantity input module is handled by 2 button input realization abnormal conditions and abnormal conditions dispose, the digital quantity output module then is red by driving, yellow two kinds of color LED lamps, expression is in two states in abnormal conditions generation or the abnormal conditions processing, switch by corresponding button input carrying out state, CAN bus communication interface is responsible for accepting the various rub-out signals that Shop Floor Controller sends.
The present invention, described system monitoring alarm host machine comprises administration module, module is set, display module, enquiry module, configuration module and help module.
Wherein administration module is used for the basic management of system, comprises system login, communication, and user management, synchronous clock, system withdraws from.The setting that module comprises various systematic parameters is set.Display module and enquiry module be running status, rub-out signal and the historical rub-out signal of the various device in managerial personnel show the workshop real-time and accurately.The configuration module is the operation of main system-oriented input/output port, CAN address card.Help module mainly comprises general description to system, guide for use etc.
The invention has the beneficial effects as follows:
1, each workshop is all independently controlled by a Shop Floor Controller, constitutes distributed control model, is convenient to system extension.The controller in certain workshop breaks down and can not impact total system.
2, utilize the conflict arbitration mechanism of CAN bus and multi-master communication structure to realize that message exchange is reliable at a high speed between each Node Controller and system management main frame.
3, this monitoring and alarming system equipment cost is low, function is strong, reliability is high, is easy to promote the use of.
