Description

A kind of condensation self-actuated controller

Technical field

The utility model relates to a kind of condensation self-actuated controller.

Background technology

Humiture environmental requirement in order to ensure special occasions such as switch cubicle, mid-cabinet, wine cellars tends to set up well heater in these environment, 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 express its duty and break down.

The utility model content

Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of condensation self-actuated controller, and it can be according to the real-time control heater work of ambient humidity situation, and can clearly show the duty of well heater.

Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of condensation self-actuated controller comprises MPU, control loop, failure analysis module and warning device, is connected with man-machine communication's device on the MPU; Described control loop comprises humidity sensor, is built in control module, photoisolator, galvanometer and well heater in the MPU, the input end of the output termination control module of humidity 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; 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 as follows:

Humidity sensor is used for ambient humidity is detected, and testing result is transferred to MPU;

Man-machine communication's device is used for setting the humidity 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 in real time to the electric current of circuit loop, 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 set the humidity ideal value by man-machine communication's device, described man-machine communication's device can comprise mouse key, LCD etc., perhaps panel button, panel knob, panel display window, pilot lamp etc.Again humidity sensor is placed in the environment to be detected ambient humidity is detected.MPU compares actual value and the ideal value of detected ambient humidity, judge whether and to adjust ambient humidity: do not need environment is heated adjustment if judge, then do not produce and allow the control command of circuit loop conducting, galvanometer does not produce current signal; If judge and need heat adjustment to environment, then produce and allow the control command of circuit loop conducting, galvanometer produces 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, illustrates that circuit loop does not have operate as normal, and warning device is reported to the police.

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

Preferably, described control loop is one the road or more than the two-way, just can carry out a relatively more three-dimensional adjustment to ambient humidity by a condensation self-actuated controller like this.

Beneficial effect: the condensation self-actuated controller that the utility model provides, can detect and adjust ambient humidity in real time, ambient humidity is maintained in the ideal range all the time, the state of ambient humidity and the duty of well heater all show by man-machine communication's device simultaneously, and the duty of controller comes into plain view.
