Cold chain equipment temperature control system and method based on GPRS technology OpenCPU development platform

Abstract

The invention discloses a cold chain equipment temperature control system and method based on a GPRS technology OpenCPU development platform. The system comprises a temperature controller terminal anda cloud platform server. The temperature controller terminal is connected with the cloud platform server through a GPRS network. The temperature controller terminal comprises a power supply module, aGPRS module, an MCU processing module connected with the GPRS module, a debugging interface module, a burning interface module, an SIM card driving module, and a temperature detection module, a temperature control module and a WIFI module which are connected with the MCU processing module. The GPRS module comprises a GPRS module with a built-in Internet of Things chip; the Internet of Things chipcomprises an APPS processor integrated with the Internet of Things chip. The OpenCPU development platform based on the GPRS technology is carried in an APPS processor. An API interface function usedfor client development is developed and packaged; a driving program and an application program are developed on a programmable framework integrated with an APPS processor, service protocol data packaging and communication with a cloud platform server are completed, the development difficulty is reduced, the development period is shortened, higher safety is achieved, and the running stability of the system is improved.

Description

technical field [0001] The invention relates to the technical field of temperature control, in particular to a cold chain equipment temperature control system and method based on the GPRS technology OpenCPU development platform. Background technique [0002] With the improvement of living standards and economic development, great changes have taken place in the consumption structure and consumption demand of Chinese residents. The demand for fresh food such as melons and fruits, vegetables, dairy products, and fresh meat products is gradually increasing. In the past ten years, China's food consumption market has grown steadily, which has brought broad development space for the cold chain equipment (freezers, refrigerators, incubators and cooler bags, etc.) industry. The cold chain process relies on cold chain equipment. The cold chain equipment must be additionally equipped with a monitoring system for freezing, refrigerating or heat preservation, and it must be continuously...

Problems solved by technology

[0005] The present invention mainly solves the technical problems of poor security, complex design and development, and low degree of integration of the original cold chain monitoring equipment; it provides a cold chain equipment temperature control system and method based on the GPRS technology OpenCPU development platform, and the GPRS in the temperature controller terminal The module includes a GPRS module with a built-in Internet of Things chip. The Internet of Things chip includes an integrated APPS processor. The OpenCPU development platform based on GPRS technology is installed in the APPS processor, and the API interface function for customer development is developed and packaged. The APPS processor Integrated with a programmable framework, the programmable framework is used for secondary development of customer drivers and applications. Customers can realize the main control function of the thermostat terminal only through simple secondary development, which reduces the difficulty of development and shortens the time. In the development cycle, the main control function is integrated with the GPRS network, which improves the integration of the thermostat terminal and improves the security of information interaction with the cloud platform server
