The beneficial effects of the utility model are: can be in normal switch board temperature, and hummer was reported to the police 2 minutes immediately after the power down, continued thermometric 20 hours, reached the purpose that power down is reported to the police, continued thermometric, reliable detection cabinet temperature.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an electric theory diagram of the present utility model;
Fig. 2 is the specific embodiment of the utility model circuit diagram;
Fig. 3 power down of the present utility model is reported to the police and is reached the control flow chart that continues thermometric.
Fig. 4 is a mode of operation operation control flow chart of the present utility model.
Embodiment
As shown in Figure 1, power down report to the police and the medical temperature controller that continues thermometric by LCD MODULE 1, key-press module 2, energy supply control module 3, temperature-measuring module 4, detection of power loss module 5, storage and copy card module 6, control output module 7, alarm module 8, single-chip microcomputer is formed.LCD MODULE shows each duty and running mark; Key-press module carries out the adjustment of parameter and menu; Temperature-measuring module is used for external power source and just often measures in-cabinet temperature; Storage and copy card module are used for storing, duplicate, the uploading system parameter; Energy supply control module carries out voltage stabilizings at different levels, detection of power loss, charging, power management switching; It is temperature survey in the power down 20 hours that the detection of power loss module is used to have a power failure; Alarm module surpasses in the cabinet temperature that high low temperature, sensor break down, report to the police during power down; Functions such as the operation of control output module control compressor, defrost.Pass through thermistor
As shown in Figure 2, in the present embodiment, single-chip microcomputer adopts the UPD78F0361 single-chip microcomputer of NEC Corporation.Temperature-measuring module and detection of power loss module adopt thermistor to gather the in-cabinet temperature data respectively.Because hummer power consumption is relatively large, common charged lithium cells charging needs the regular hour, can't adapt to the requirement of fast charging and discharging, this controller utilizes that volume is little, capacity is big, power supply realizes reporting to the police immediately after the power down to hummer separately to discharge and recharge a fireballing farad capacitor OC1.Under the relatively little situation of controller volume and cost space, adopt the button charged lithium cells to provide standby power supply to controller, this just requires the strict control of the power consumption of controller, adopt the liquid crystal display low-power scm, when outside power down, close other module single-chip microcomputer rapidly and enter dormant state and only keep batch (-type) temperature acquisition and demonstration.
Power down is as shown in Figure 3 reported to the police and is reached the control flow chart that continues thermometric, the middle fracture of single-chip microcomputer is responsible for the power supply electro-detection of system, when by external power source, system carries out rapid charge to farad capacitor lithium battery is carried out trickle charge, when system's power down, the rapid Switching power of system, system enters dormant state, close except that thermometric and other module for power supply showing, power supply provides the electric weight of reporting to the police 2 minutes to farad capacitor to hummer, lithium battery is powered to system, keeps 20 hours temperature survey and demonstration.
In mode of operation shown in Figure 4 operation control flow chart, be provided with A, the Administration menu of two kinds of patterns of b, two kinds of operation control models are optional: in elected after certain operational mode, the scope that is provided with of parameter, default value and operation control method are according to selected mode operation.In the A pattern, last electric alarm, defrosting are reported to the police, reported to the police, and it is invalid to delay time, high low-temperature warning adopts the cumulative time to report to the police, cut off the power supply and force the on time to adopt the control of three stages after 12 hours after the energising, in the b pattern, time-delay is reported to the police, reported to the police to last electric alarm, defrosting effectively, and high low-temperature warning adopts to report to the police immediately and can delay time but do not add up, and force to start shooting in the energising back that cut off the power supply after 12 hours; In addition, A pattern and b pattern are controlled the operation of defrost and compressor according to the method for operation separately.
