Technical field
The present invention relates to a kind of temperature and humidity controller.
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.What but existing controller can only be independent perhaps controls well heater according to the humidity situation according to temperature conditions.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the present invention provides a kind of temperature and humidity controller, and it can be monitored temperature and humidity simultaneously, in time adjusts environment temperature.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of temperature and humidity controller comprises main frame, sensor and temperature adjustment device, and said main frame comprises A/D converter, temperature setting device, MPU and switch, and said sensor comprises temperature sensor and humidity sensor; Said temperature sensor is connected with the sensor monitoring input end of MPU through the A/D converter with humidity sensor, and temperature setting device is connected with the preset temperature input end of MPU, and the output terminal of MPU is connected with temperature adjustment device through switch; Said temperature adjustment device is a well heater.
Said temperature adjustment device can also be condenser; Perhaps can also comprise condenser; Through changing the concrete selection of temperature adjustment device, can design temperature and humidity controller is the temperature and humidity controller that heating type temperature and humidity controller, cooling type temperature and humidity controller or lifting/lowering temperature function possess simultaneously.
Above-mentioned controller needed at first set needed environment temperature through temperature setting device in when work, MPU (microcontroller) according to set environment temperature and sensor to ambient conditions determine whether to open temperature adjustment device; In temperature adjustment device when work,, temperature sensor and humidity sensor detect ambient conditions simultaneously, and when ambient conditions exceeded predefined temperature environment certain limit, MPU ordered about temperature adjustment device and quits work.
Said main frame is installed in the main case, on main case, is provided with structure of mounting hole, and this temperature and humidity controller fixedly mounts through structure of mounting hole when mounted.
Said switch is preferably photoisolator, the signal one-way transmission of photoisolator, and its input end and output terminal have been realized electrical isolation fully; The output signal does not have influence to input end, and antijamming capability is strong, working stability; Contactless, long service life, transfer efficiency is high.
Said temperature setting device can be designed as the knob structure that has pointer that is fixed on the main case panel, and during use, the staff can set preset temperature through manual adjustment.
Said temperature sensor and humidity sensor can adopt the Temperature Humidity Sensor of one design.
Beneficial effect: temperature and humidity controller provided by the invention, can monitor field temperature and humidity simultaneously, in time environment temperature is adjusted.

Embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
Be illustrated in figure 1 as a kind of temperature and humidity controller, comprise main frame, sensor and temperature adjustment device, said main frame comprises A/D converter, temperature setting device, MPU and switch, and said sensor comprises temperature sensor and humidity sensor; Said temperature sensor is connected with the sensor monitoring input end of MPU through the A/D converter with humidity sensor, and temperature setting device is connected with the preset temperature input end of MPU, and the output terminal of MPU is connected with temperature adjustment device through switch; Said main frame is installed in the main case, on main case, is provided with structure of mounting hole; Said temperature adjustment device is well heater or condenser.
In this example, concrete design circuit is as shown in Figure 2, and wherein switch adopts photoisolator, and the pin annexation of main frame and sensor and temperature adjustment device is as shown in Figure 3, and load shown in the figure is temperature adjustment device.
Based on Fig. 2 and Fig. 3; Can be in like Fig. 4 and main case I shown in Figure 5 with the design of main frame and temperature adjustment device; Wherein shown in Figure 4 also is the host panel of temperature and humidity controller; Temperature setting device is the knob structure that has pointer on the main case panel, and the duty of power supply access state, temperature adjustment device can both show very legibly like this, and this main case I is fixedly mounted in the environment through structure of mounting hole; Temperature sensor and humidity sensor adopt the Temperature Humidity Sensor of one design, are positioned in Fig. 6, the sensor shell II shown in Figure 7.
This example is based on Fig. 1～7, the performance correlation parameter such as the table 1 of the temperature and humidity controller of designing:
Table 1 temperature and humidity controller performance parameter design table
The concrete duty of above-mentioned temperature and humidity controller is following:
1, circuit is connected, and power light is bright.
2, rotary knob treats that relay indicating light is bright, and this moment, pointer was lower than (cooling type temperature and humidity controller, condenser) or a little higher than (heating type temperature and humidity controller, well heater) environment temperature slightly to scale.
3, rotary knob to required design temperature, temperature adjustment device is started working when treating the temperature liter or reducing to design temperature:
Heating type temperature≤design temperature is started working
Temperature >=design temperature+5 ℃ quit work
Cooling type temperature >=design temperature is started working
Temperature≤design temperature-5 ℃ quits work
4, condensation control:
Humidity >=90%RH starts working
Humidity≤85%RH quits work
5, before the use, need sensor be fixedly mounted in the environment for use.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
