Description
Technical field
The utility model relates to the automatic control technology field, is specifically related to a kind of industrial online redundancy control system that is used for.
Background technology
Use in blower fan, the water pump production system in industry; Blower fan, water pump are the power maincenters, do not allow during the ordinary production to restart behind the hang-up, in case frequency converter self breaks down in frequency conversion speed-adjusting system; Cause blower fan; Pump motor can not normally move, and not only influence is produced, and causes heavy losses; So must guarantee the stable operation of blower fan, water pump.But, in the prior art, mostly the single channel structure in the industrial system, promptly have only main road work not have the branch road Hot Spare.The problem of its existence is that the fault-resistant ability is low, in case a certain link breaks down in the control loop, the lighter causes the total system equipment downtime, influences ordinary production, and weight person causes security incident.
The utility model content
To the above-mentioned deficiency that prior art exists, the purpose of the utility model is to provide a kind of industry online redundancy control system, realizes the Synchronous Switching Based Intelligent Control, and the normal operation with blower fan or pump motor in the assurance production line guarantees to produce normally.
The purpose of the utility model is achieved in that the online redundancy control system of a kind of industry, it is characterized in that, comprises switch board and the mutually redundant pressure transducer of two covers, PLC controller, frequency converter, motor and water pump; Said pressure transducer is installed in and detects hydraulic pressure on the pipe network in real time; Output 0～10V/4～20mA electric signal; As the feedback signal of PLC controller, the PLC controller carries out the comprehensive computing of P (ratio) I (integration) D (differential) according to the feedback signal and the frequency converter job parameter at that time of pressure transducer; Adjust the output state and the job parameter of frequency converter in real time, with the rotating speed of control electric water pump; Switch board links to each other with two frequency converters;
The mutually redundant pressure transducer of said two covers, PLC controller, frequency converter, motor and water pump are electrically connected respectively successively, and two cover systems work alone, a cover job, and a separate set of is subsequent use; When an equipment of any cover occurs when unusual, system's failure judgement unit control should cover contract fully, starts other cover work.
The mutually redundant pressure transducer of perhaps said two covers, PLC controller, frequency converter, motor and water pump two cover system cross connections; Promptly two sleeve pressure sensor link to each other with two cover PLC controllers respectively; Two cover PLC controllers link to each other with two cover frequency converters respectively; Two cover frequency converters link to each other with motor respectively, and two cover motors link to each other with two cover water pumps respectively; A set of equipment work, a separate set of is subsequent use; When an equipment of any cover occurs when unusual, the corresponding parts work of system's failure judgement parts automatically starting backup, and send alarm, other subsequent use parts are still subsequent use.
The beneficial effect of the utility model is: adopt the two-node cluster hot backup scheme, to guarantee more reliable, the safety of system works.System body adopts two-way parallel connection scheme, just often, and one tunnel work, another road real-time follow-up backup.Give birth to fault in case wherein riches all the way, system automatically switches to another road and takes over job, and guarantees no system disturbance phenomenon simultaneously.Can reduce because the system failure causes shutdown, avoid causing ordinary production; Can prolong average accident-free duration of system and service life of equipment on the other hand, reduce production costs.
Use two cover industrial control computers to constitute dual-machine hot backup system, when there is problem in a system, take over job automatically for other one.This programme had both guaranteed the reliability of system, had simplified the structure of system again.Maintainability, expandability and the manageability of total system are greatly improved.
The frequency converter of Hot Spare is that the frequency converter normal work period does not have output voltage, i.e. not power consumption of the frequency converter of Hot Spare self.Take the reliability and the stability of the long-time running of this frequency converter standby mode high voltage converter that principal security is selected for use, simultaneously influence ordinary production at frequency converter self Shi Buhui that breaks down.
