Judge whether there is door opening action in time T, and further judges whether have closing door dynamic in the case where door opening action occurs
Make, if closed the door, reenters temperature value judgment module progress temperature monitoring if do not closed the door and carry out shutdown prompt；Judge
It then indicates that internal temperature of refrigerator element is abnormal in time T without door opening action, carries out yellow alarm, and be again introduced into temperature value judgement
Module if temperature value is more than preset temperature limit value, while carrying out door switch, power consumption values and judging extremely, such as moves without opening the door in time T
Make, carries out red alarm.
Further, data acquisition module is in the measurement of resistance temperature sensor value, the range setting for carrying out gamut scope
When with the conversion of temperature-resistance value, server is carried out beyond the clouds.
A kind of cloud monitoring of low temperature refrigerator temperature disclosed by the invention and failure warning system and method, have with following
Beneficial effect:
1, low temperature refrigerator temperature, energy consumption (electric current, power), the information of door opening and closing state are acquired using wireless monitoring terminal,
Without that can be connect by wifi module or gsm module with Ethernet by other radio receiving terminals, after data encryption
It is transferred to cloud server, simplifies ultra low temperature freezer temperature monitoring system, and guarantee its Information Security.
2, the prior art is different for the operating temperature of Different hypothermia refrigerator, and the temperature for needing to be equipped with different range abilities passes
Sensor (PT100 thermal resistance), the method that ordinary temperature monitoring device uses the sample circuit hardware module of matching different size.This
Invention guarantees that wireless monitoring terminal can accurately measure the temperature of gamut scope using the method for assembly high-precision AD conversion chip
Sensor resistance, and range setting and the conversion of temperature-resistance value are placed on cloud server and implemented, wireless monitor end can be exempted
The matching production procedure at end and temperature sensor, and improve the flexibility of hardware update maintenance, reduce the life of total solution
Produce cost
3, existing ultra low temperature freezer temperature pre-warning system is all made of simple direct temperature over-range judgment method.Therefore originally
Patented invention is based on MULTISENSOR INTEGRATION alarming method by monitoring, using temperature, energy consumption (electric current, power) sensor, door switch
Multiple sensors monitor ultra low temperature freezer state, the method for comprehensive descision ultra low temperature freezer failure, and can provide fault pre-alarming and
Alarm two types information.
