Abstract
An electric cabinet temperature controller comprises a central processor, a logic control unit, a program control unit, a temperature sensing unit, a signal amplifying unit and an I/O channel output unit of an existing controller inside an electric cabinet. The temperature controller uses the microcomputer controller inside the electric cabinet instead of a temperature probe, a switch or a relay, can not only control and operate an electric device, but also control running of a heat dissipating fan by the aid of the original central processor and the logic control unit inside the controller and via the program control unit, the temperature sensing unit, the signal amplifying unit and the I/O channel output unit, and realizes automatic control of temperature inside the control cabinet.
Description
Technical field
The utility model relates to the inner detected temperatures of a kind of electrical control cubicles, the temperature control aut.eq. of cooling fan running in the switch board, especially need not temp probe, switch, can detect the switch board internal temperature, the running of control cooling fan realizes the automatic control of electrical control cubicles internal temperature.
Background technology
At present, the cooling fan automaton that all electrical control cubicles are used is made up of temperature sensor probe, temperature controller, relay.The electrical control cubicles temperature is sent into temperature controller through the analog temperature signal that temperature sensor probe picks up, and handles through temperature controller, according to required set temperature value output switching value signal, the running of control cooling fan, temperature control precision is low, the cost height, volume is big, takies the switch board space.
The utility model content
In order to overcome the cooling fan automaton that existing electrical control cubicles is used, precision is low, the cost height, volume is big, takies the shortcoming in switch board space, and the utility model provides a kind of temperature induction unit by the central processing unit outside surface of electrical control cubicles inside microcomputerized controller own, by logical operation, programmed control, signal amplifies, the I/O passage is exported, the running of control cooling fan, realizes the automatic control of switch board internal temperature.
The technical scheme that its technical matters that solves the utility model adopts is: be made up of the microcomputerized controller in the electrical control cubicles, central processing unit, arithmetic logic unit, procedure control unit, temperature induction unit, signal amplification, I/O passage output unit.Temperature induction unit is by the outside surface of central processing unit, sense the switch board temperature inside, through the arithmetic logic unit computing, the temperature value comparative analysis of procedure control unit and setting, handle through central processing unit, amplify, by the running of I/O passage output switching signal notice cooling fan by signal, cooling fan feedback operating condition realizes the automatic control of electrical control cubicles internal temperature to procedure control unit.
The beneficial effects of the utility model are, the microcomputerized controller of electrical control cubicles inside, both may command actuating control panel the time, again can be by the temperature induction unit of the original central processing unit outside surface of controller, by logical operation, programmed control, the running of control cooling fan, realize the automatic control of electrical control cubicles internal temperature, the temperature control precision height need not to increase cost and electrical control cubicles space.
