Description

A kind of Automatic Temperature Control

Technical field

The utility model relates to a kind of Automatic Temperature Control.

Background technology

Humiture environmental requirement in order to ensure special occasions such as switch cubicle, mid-cabinet, wine cellars tends in these environment, set up well heater, and the controller of well heater passes through the heated condition to the monitoring situation control heater of temperature, humidity.Whether but existing controller is not owing to there are parts such as pilot lamp, can not show its duty clearly and break down.

The utility model content

Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provides a kind of Automatic Temperature Control, and it can be according to the real-time control heater work of ambient temperature situations, and can clearly show the duty of well heater.

Technical scheme: for solving the problems of the technologies described above, the technical scheme that the utility model adopts is:

A kind of Automatic Temperature Control comprises MPU, control loop, failure analysis module and warning device, the last man-machine communication's device that is connected with of MPU; Said control loop comprises temperature sensor, is built in control module, photoisolator, galvanometer and well heater in the MPU; The input end of the output termination control module of temperature sensor; Forming circuit loop after the input side of the output termination photoisolator of control module, the outgoing side of photoisolator are connected with galvanometer, well heater; The output terminal and the galvanometric output terminal of the input termination control module of failure analysis module, output terminal device taking alarm; The various piece function is following:

Temperature sensor is used for environment temperature is detected, and testing result is transferred to MPU;

Man-machine communication's device is used for the design temperature ideal value, and setting value is transferred to MPU;

MPU calculates, analyzes the data that receive, and produces control command, and control command is transferred to photoisolator and failure analysis module;

Photoisolator is according to control command, conducting or turning circuit loop not;

Galvanometer detects the electric current of circuit loop in real time, and testing result is transferred to failure analysis module;

The fault analysis mould calculates, analyzes the data that receive, and whether break down in the decision circuitry loop, and judged result is transferred to warning device;

Warning device is made the response of whether reporting to the police according to judged result.

During use, at first through man-machine communication's device design temperature ideal value, said man-machine communication's device can comprise mouse key, LCD etc., perhaps panel button, panel knob, panel display window, pilot lamp etc.Again temperature sensor is placed in the environment to be detected environment temperature is detected.MPU compares the actual value and the ideal value of detected environment temperature; Judge whether and to adjust environment temperature: need not heat adjustment environment if judge; Then do not produce and let the control command of circuit loop conducting, galvanometer does not produce current signal; If judgements need heat adjustment to environment, then produce and let the control command of circuit loop conducting, galvanometer generation current signal.Failure analysis module is analyzed the data that receive: if control command is the circuit loop conducting, galvanometer detects current signal, and the circuit loop operate as normal is described, warning device is not reported to the police; If control command is the circuit loop conducting, galvanometer does not detect current signal, explains that circuit loop does not have operate as normal, and warning device is reported to the police.

Preferably, the outgoing side of said photoisolator is parallel with hand switch, just can force well heater to heat through manual control like this, and the control command that not produced by MPU influences.

Preferably, said control loop is one the road or more than the two-way, just can carry out a relatively more three-dimensional adjustment to environment temperature through an Automatic Temperature Control like this.

Beneficial effect: the Automatic Temperature Control that the utility model provides; Can detect and adjust environment temperature in real time; Environment temperature is maintained in the ideal range all the time; The state of environment temperature and the duty of well heater all show through man-machine communication's device simultaneously, and the duty of controller comes into plain view.
