Abstract

The invention provides a data compression method and a data compression device suitable for remote meter reading, wherein the method comprises the following steps of: acquiring data of a meter, and determining the maximum data in the data; calculating transformation parameters based on the maximum data and a preset data transformation algorithm; and transmitting the transformation parameters and the maximum data as data of the remote meter reading, thereby reducing the data transmission time, reducing the data traffic between the remote meter reading device and the data communication device and between the data communication device and the server, reducing the working times of the remote meter reading device and the data communication device, saving the power consumption, and prolonging the battery life. At the same time, since the maximum data may be used as a check digit, the check digit can be correspondingly reduced in the data transmission, the bit number of data that needs to betransmitted is also decreased, and the system power consumption of the remote meter reading device and the data communication device is further reduced.

Description

technical field [0001] The invention belongs to the technical field of remote meter reading, and in particular relates to a data compression method and device suitable for remote meter reading. Background technique [0002] For a long time, my country's civilian instruments, such as electric energy meters and heat meters, are all inductive mechanical instruments, and the original method of manual meter reading has to be used to obtain instrument data, among which electric energy meters are the most prominent. With the rapid development of our country's national economy, the improvement of people's living standards, and the continuous expansion of housing complete sets and commercialization, residents have higher and higher requirements for the surrounding environment of housing, the management quality of property departments, and the level of public service services. It is increasingly obvious that the traditional manual meter reading method does not adapt to the development...
