Problems solved by technology

[0003] Although the above temperature control methods meet the control requirements of the refrigerator, they all have the following problems: 1) Lack of fault self-detection function, when the refrigerator fails, the alarm information cannot be displayed in real time according to the type of fault
2) There is no remote operation function. The existing refrigerator control system needs to be operated under human supervision and cannot be remotely controlled.
3) There is no regular transmission of temperature data. At present, some thermostats can only transmit the alarm information to the operator remotely when there is an alarm. For example, the patent (200420030089.8) only transmits the alarm information to the operator through the GSM module. The measured temperature is not regularly transmitted to the operator
4) It is impossible to query the historical temperature data in real time and change the control strategy through the local PC

Embodiment Construction

[0024] 1. Local control: mainly includes local parameter setting, temperature control, defrosting control, and alarm disposal.

[0025] Local parameter setting: After the system is started, the operator can set the control parameters of the main controller [7] locally through the button [10], mainly including: temperature control parameters, defrosting control parameters, and alarm parameters. After the control parameters are set, the main controller [7] automatically saves the parameters to the data storage [9] module, and then controls the refrigerator according to the new control parameters.

[0026] Temperature control: After the system starts, the operator completes the setting of the temperature control parameters of the main controller [7] through the local parameter setting. The main controller [7] collects the temperature information of the refrigerator according to the refrigeration probe [23] of the temperature detection module [21], compares it with the temperatur...

Abstract

The invention relates to a remote intelligent freezer temperature control system. The system adopts the combination of keys, a mobile phone and a local PC (personal computer) to control the temperature of a freezer. A master controller is connected with the local PC through a serial communication module and a wire, wirelessly connected with the mobile phone through a GSM (Global System for Mobile Communication) communication module, base stations and a mobile network subsystem and directly connected with a data memory module through an IIC (Inter-Integrated Circuit) port to store historical data. The remote intelligent freezer temperature control system has the following advantages that: (1) the mobile phone can set the parameters of the master controller and receive alarm and temperature information; (2) the local PC can set the parameters of the master controller and read temperature data and fault records; (3) temperature and faults can be automatically recorded; (4) the freezer temperature control mode is diversified. In a word, the application range of the remote intelligent freezer temperature control system is wide, the control mode is flexible, the remote intelligent freezer temperature control system is suitable for the unattended control of the freezer, and can be applied to control various freezers, and economic and social benefits are enormous.

Description

technical field [0001] The present invention is a new type of remote intelligent temperature control system for refrigerators used in household or commercial refrigerators. This system realizes temperature acquisition, temperature control, local PC control, and remote monitoring functions through GSM, embedded technology, etc., and promotes the temperature control of refrigerators. System intelligence. Background technique [0002] Before the present invention was made, according to the difference of the refrigeration control system, the control of the freezer could be divided into two types: mechanical temperature control and electronic temperature control. Mechanical temperature control refers to a temperature control method that mechanically adjusts the refrigeration of the freezer. This method was applied earlier, and the system is relatively simple, which can ensure the basic requirements of temperature control: food does not deteriorate, but the temperature is unstable...
