Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
The warning self-checking circuit thermostat container schematic circuit that Fig. 1 provides for the utility model embodiment;
The temperature alarm circuit figure that Fig. 2 provides for the utility model embodiment.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only in order to the utility model is described, instead of in order to limit protection domain of the present utility model.
As shown in the figure, the one warning self-checking circuit thermostat container that the utility model provides, comprises framework, well heater, refrigerator, temperature sensor, controller, temperature alarm circuit and self-checking circuit;
Culturing room is provided with in described framework; Described temperature sensor to be arranged in culturing room for the temperature signal that obtains in culturing room and temperature signal is transferred to controller; Described controller is connected with well heater, refrigerator and overtemperature and warning circuit of lowering the temperature respectively; Described well heater is for raising the temperature of culturing room inside; Described refrigerator is for reducing the temperature of culturing room inside; Described temperature alarm circuit is used for sending guard signal during temperature departure predetermined normal level in culturing room; Described self-checking circuit is connected whether occur fault for detected temperatures warning circuit with temperature buzzer.
Described self-checking circuit comprises observation circuit, circuit parameter treatment circuit and pilot lamp;
Described observation circuit, for acquisition cuicuit actual parameter value; Described circuit parameter treatment circuit, obtains for comparison circuit actual parameter and circuit normal operating parameters the order controlling pilot lamp; Described pilot lamp, the order exported for receiving circuit parameter processing circuit is also communicated with or disconnects the circuit of pilot lamp;
Described observation circuit, circuit parameter treatment circuit are connected successively with pilot lamp.
Described self-checking circuit also comprises by compressing switch, switch lever and elastic washer;
In described pressing switch-linear hybrid framework; Describedly by compressing switch framework junction is provided with elastic washer; Described by compressing switch for the on off state by pressing down control self-checking circuit; Described by compressing switch and being provided with preset clearance between framework, the gap width of described preset clearance is slightly less than the amount of elastic deformation of elastic washer.
The temperature alarm circuit that the present embodiment provides also can adopt CD4011 tetra-Sheffer stroke gate unicircuit to form; Report to the police when overtemperature and cooling, for the temperature monitoring thermostat container, or when constant-temperature circuit breaks down or has a power failure, when the temperature inside the box is higher or lower than allowed scope, it all can sound the alarm, and reminds people to note taking corresponding measure.This circuit has the resolving power of 0.1 DEG C.
Diode VD1 and VD2 is all placed in thermostat container, and when the temperature inside the box is lower than lower value, in figure, a point current potential is greater than the threshold voltage U of an A input terminus, door A output terminal is lower level, make a B export high level, the multivibrator starting of oscillation be at this moment made up of door C, door D, piezoelectric patches sends chimes of doom; When the temperature inside the box is higher than higher limit, b point current potential is less than a B threshold voltage U, and a B also can be made to export high level, and piezoelectric patches YD sends chimes of doom.Only have when the temperature inside the box is in the value between upper and lower limit, YD just can not send the sound.Regulate the value of RP1 and RP2 can change lower limit and higher limit respectively respectively.Power source circuit is ac-dc dual power supply, and E is standby power supply, and when AC power has a power failure, VD3 conducting, standby power supply is powered to circuit, and because the power consumption of this circuit is very micro-, standby power supply can use layer-built battery, to reduce volume.
