Abstract
The utility model discloses a PLC control thermostat. The device comprises an enclosed square shaped casing, a control panel that is arranged on the external part of the casing for a user to input instructions and to display temperature information, six temperature sensors arranged on the internal six surfaces of the casing, six heaters arranged on the internal six surfaces of the casing, and a core PLC control unit that receives control signals from the control panel and the temperature signals from the temperature sensors; based on the signals the core PLC control unit decides to heat or stop heating a component that needs heating and at the same time, outputs information on temperature to the control panel. The PLC control thermostat is suitable to be applied to hatching equipment that has a large volume.
Description
Technical field
The utility model relates to a kind of thermostat, especially a kind of PLC control thermostat.
Background technology
Thermostat is in the usual means that is used on the incubation equipment, requires its temperature inside during incubation can remain in the very little numerical value interval of excursion, thereby guarantees temperature substantial constant in the hatching process.Traditional thermostat is used a temperature sensor detected temperatures always, heats simultaneously or stops simultaneously according to the institute's having heaters on the detected temperature information control thermostat.For an incubation equipment that volume is bigger; Because its inner space is big; The temperature of each position is not necessarily identical; The detected Temperature numerical of sensor can not reflect the temperature conditions of each several part in the casing well, so the control mode that institute's having heaters heats synchronously or stops can not to guarantee desirable constant temperature, thereby has also just influenced the success rate of hatching.
Therefore, a kind of thermostat that goes for big volume incubation equipment can appear in hope.
The utility model content
The utility model technical problem to be solved provides a kind of thermostat that can A.T.C, especially a kind of PLC control thermostat that goes for big volume incubation equipment.
For solving the problems of the technologies described above, the PLC control thermostat of the utility model comprises an airtight square box, comprises that also one is arranged on the input control order of said casing outside and the control panel of displays temperature information; Six six lip-deep temperature sensors that are separately positioned in the said casing; Six six lip-deep heaters that are separately positioned in the said casing; And control core PLC unit; Receive the control signal of said control panel transmission and the temperature signal that said temperature sensor sends; Control the heating of the heater corresponding respectively or stop heating according to above-mentioned control signal and said temperature signal with said temperature signal, and to said control panel output temperature information.
With respect to prior art, the advantage of the utility model is:
The PLC unit can control the heating of the heater corresponding with each sensor respectively or stops according to the detected Temperature numerical of temperature sensor on the thermostat casing inner surface; Thereby the heating-up temperature that can control six surfaces in the thermostat all remains in the setting range; Control accuracy of temperature improves greatly, thereby can produce the thermostat with big internal capacity.
Description of drawings
Fig. 1 is the structural principle sketch map of the utility model.
Embodiment
Below in conjunction with Figure of description the utility model is done further description.
In one embodiment, as shown in Figure 1, said PLC control thermostat comprises an airtight square box, comprises that also one is arranged on the input control order of said casing outside and the controller of displays temperature information; Six six lip-deep temperature sensors that are separately positioned in the said casing; Six six lip-deep electric heaters that are separately positioned in the said casing; And control core PLC unit; Receive the control signal of said controller transmission and the temperature signal that said temperature sensor sends; Control the heating of the heater corresponding respectively or stop heating according to above-mentioned control signal and each temperature signal with temperature signal, and to said controller output temperature information.
Action with first temperature sensor 1 and primary heater 11 is controlled to be the example explanation as follows:
First temperature sensor 1 is arranged on the same inner surface in the casing with primary heater 11.Whole thermostat is set heating-up temperature and variation of temperature scope bound through control panel; These setting values are input in the PLC unit through control panel; The Temperature numerical information on first temperature sensor 1 is monitored in real time according to the program that configures in advance in the PLC unit.Prescribe a time limit when this Temperature numerical information is lower than the following of setting range, 11 energisings of PLC unit controls primary heater are heated.Reach or exceed going up in limited time of setting when first temperature sensor 1 monitors temperature value, 11 outages of PLC control primary heater stop heating.To sum up, first temperature sensor 1 monitors that temperature is lower than setting following in limited time, primary heater 11 energisings are heated; First temperature sensor 1 monitors temperature and is equal to or higher than going up in limited time of setting, and primary heater 11 outages stop heating.Thereby the temperature that produces on the inner surface that just makes primary heater 11 belong to remains in the setting range.
Likewise, second, third, the 4th, the 5th, the 6th temperature sensor 2～6 corresponding respectively second, third, the 4th, the 5th, the 6th heater 22,33,44,55,66 is provided with, control through the PLC unit.Each the lip-deep temperature that so just reaches in the above-mentioned PLC control thermostat can be controlled in the setting range respectively.Thereby the temperature in the whole thermostat during incubation keeps constant relatively.
More than; Be merely the preferred embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claim was defined.
