Summary of the invention

The defective that the utility model can not be controlled the control system of freezer to humiture checkout equipment in the prior art automatically; A kind of humiture remote monitor is provided; Can carry out automatic open close to the general supply in the freezer, refrigeration machine, blower fan, defrost equipment according to the requirement of the humiture of setting; Guarantee that the article that store in the freezer meet the humiture requirement, avoid producing unnecessary loss.

In order to solve the problems of the technologies described above, the technical scheme of the utility model is following:

A kind of temperature and humidity monitor appearance; The power module that comprises central processing module, temperature collect module, humidity acquisition module, clock module, display module, relay control module and operating voltage is provided for whole humiture remote monitor; Temperature collect module, humidity acquisition module, clock module, display module, relay control module link to each other with central processing module respectively; Described relay control module has many to switch contact, and each is connected respectively to switch contact in the supply line of general supply, refrigeration machine, blower fan, defrost equipment of freezer.

As possibility, be connected with the sound and light alarm module on the described central processing module.

As possibility, be connected with the USB communication module on the described central processing module.

As possibility, be connected with memory module on the described central processing module.

As possibility, above-mentioned power module is by civil power and lithium battery power supply, and civil power links to each other with power module through the power supply handover module with lithium battery, is connected with the lithium cell charging module that links to each other with described central processing module (1) on the lithium battery.

As possibility, above-mentioned central processing module adopts embedded type CPU, and described display module adopts LCDs.

The beneficial effect of the utility model is: the utility model can be in real time controlled the general supply in the freezer, refrigeration machine, blower fan, defrost equipment with the defective humiture state of the humiture data of freezer, freezer and according to the requirement of the humiture of setting automatically; Thereby guarantee that freezer is in the humiture environment of stored article requirement always; Guarantee the quality of stored article, avoid producing unnecessary loss.The utility model all weather operations, cost is low, real-time.The utility model is supporting to have system monitoring software, can realize humiture data permanent backup, humiture data query and graphic analyses, is specially adapted to that monitoring point distance, monitoring point are disperseed, unattended occasion is used.

Description of drawings

Fig. 1 is that a kind of circuit theory of the utility model connects block diagram.

1. central processing modules among the figure, 2. temperature collect module, 3. humidity acquisition module, 4. clock module, 5. display module; 6. relay control module, 9. sound and light alarm module, 10.USB communication module, 11. memory modules, 12. power modules; 13. civil power, 14. lithium batteries, 15. power supply handover modules, 16. lithium cell charging modules, the general supply of 17. freezers; 18. refrigeration machine, 19. blower fans, 20. defrost equipment, the electric power system of 21. freezers.

The specific embodiment

Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.

Embodiment 1: a kind of temperature and humidity monitor appearance of present embodiment; As shown in Figure 1; Comprise central processing module 1, temperature collect module 2, humidity acquisition module 3, clock module 4, display module 5, relay control module 6, sound and light alarm module 9, USB communication module 10, memory module 11 and the power module 12 that operating voltage is provided for whole temperature and humidity monitor appearance.Temperature collect module 2, humidity acquisition module 3, clock module 4, display module 5, relay control module 6, sound and light alarm module 9, USB communication module 10, memory module 11 link to each other with central processing module 1 respectively.Relay control module 6 has many to switch contact, and each is connected respectively to switch contact in the supply line of general supply 17, refrigeration machine 18, blower fan 19, defrost equipment 20 of freezer.The power module 12 of present embodiment is by civil power 13 and lithium battery 14 power supplies, and the power input of civil power 13 and lithium battery 14 links to each other with power module 12 through power supply handover module 15, also is connected with lithium cell charging module 16 between the central processing module 1 of lithium battery 14.In the present embodiment, central processing module 1 adopts embedded type CPU, and embedded type CPU is selected the MSP430F247 chip for use; Clock module is selected the PCF8563 chip for use; The USB communication module is selected the FT232RL chip for use, and memory module is selected the AT24C512 chip for use, and temperature collect module is selected the NTC temperature sensor for use; The humidity acquisition module is selected Honeywell HIH5030 humidity sensor for use, and display module adopts LCDs.
