Embodiment Construction

[0024] Such as figure 1 As shown, a method for remote meter reading of utility meters in the present invention includes a host and a slave, and the host and the slave are connected by two lines. These two lines play two roles of communication and power supply. The host It includes communication configuration steps, encryption steps and communication steps between the slave machine. The communication configuration steps include the steps of initializing the bus, confirming the device steps, and performing communication steps after the encryption steps. The communication steps include data reading steps and sending after completing the communication. The interrupt step and the data reading step include data request, slave machine reply data, data readout, and then slave machine receive processing. The receive process is divided into two parts: interrupt receive process and link layer process.

[0025] In any case, the communication configuration of the remote meter reading metho...

Abstract

The invention aims to provide a remote meter reading method of a public utility meter. In the method provided by the invention, an improved and encrypted M-Bus (meter bus) transmission mode is adopted, thus the transmission mode is simplified. In order to achieve the effects, in the remote meter reading method of the public utility meter provided by the invention, a host and a slave are adopted, and the host is in communication connection with the slave through a bus and provides working power for the slave. The method comprises the following steps: a communication configuration step, a encryption step and a communication step which are carried out between the host and the slave, wherein the communication configuration step comprises a bus initialization step and an equipment determination step; the communication step is carried out after the encryption step; the communication step comprises a data reading step and a transmission interruption step after the communication step; the data reading step comprises data requesting; the slave replies and reads the data; the receiving processing is carried out on the data through the slave; and the receiving processing is divided into interruption receiving processing and link layer processing. Because the technical scheme of the invention is adopted, the M-Bus can be used for conveniently and safely realizing the functions of starting the networking and remote meter reading of meters such as an electricity meter, a water meter, a heat meter and the like.

Description

technical field [0001] The invention relates to a field bus communication mode, in particular to a remote meter reading method for a public utility instrument. Background technique [0002] M-BUS is a network system structure specially used for remote sending and receiving information of various instruments or devices. M-BUS and TSS721 chips are applied to various consumer instruments (such as water meters, electricity meters, gas meters and smoke alarm devices, etc.) It can realize functions such as remote real-time data collection, inspection and monitoring. If the system is applied to residential areas, it can realize remote meter reading, alarm, intelligent control and management, etc., which is of great significance to the intelligent construction of residential areas and the modern management of public utility management departments. In the prior art, there is also the article "Research on the Principle of M-Bus Instrument Bus", which introduces in detail the importan...
