Problems solved by technology

With the advancement of Internet of Things technology, wired transmission has been gradually eliminated as a communication medium. Sometimes the various data that need to be collected are in a special environment, and the traditional manual collection method cannot be adopted, and manual collection is time-consuming and labor-intensive. It is not accurate enough, so It is necessary to obtain data on site temperature, pressure, humidity, etc. through sensors, and use the wireless communication network to transmit these data to the data server. Users can go to the data server to obtain data and analyze and process these data.

Description

technical field [0001] The invention relates to the technical field of instrument data acquisition and transmission, in particular to a GPRS-based intelligent instrument data acquisition and transmission system and method. Background technique [0002] A lot of research has been done on the data acquisition and transmission of smart meters at home and abroad, and many system products have also been derived. In China, with the improvement of people's living standards, people have put forward higher requirements for the quietness, convenience and safety of the living environment. Meter reading disturbs residents and gas safety issues are getting more and more attention. Since 1998, Dalian, my country has promoted water, electricity, gas remote meter reading and gas leakage monitoring systems in newly built residential quarters. So far, more than 3 million residential houses have been equipped with these systems. Judging from the monitoring situation, the system is running we...
