Problems solved by technology

[0002] The data collection of traditional gas meters relies on manual door-to-door data copying. The data collection process is time-consuming and laborious, and the accuracy and timeliness are difficult to guarantee. The following problems inevitably exist: the copied data has errors and cannot truly reflect the user Actual gas consumption; operation is difficult to standardize, and it is easy to cause an increase in unknown losses; labor-intensive, high cost, and low efficiency

Embodiment Construction

[0012] The technical solution of the present invention is further described in detail below, but the protection scope of the present invention is not limited to the following description.

[0013] A method for realizing channel number identification of a photoelectric direct-reading wired remote transmission gas meter comprises the following steps:

[0014] S1: Number the I / O channels of each gas meter connected to the hub. The I / O channels correspond to the I / O channel numbers one by one. Each gas meter corresponds to an I / O channel number, and the I / O The channel number information is stored in the memory of each gas meter;

[0015] S2: The hub sends a broadcast message to each gas meter, and the broadcast message includes the I / O channel number of the designated message receiver;

[0016] S3: Each gas meter receives the broadcast message, and extracts the I / O channel number of the message receiver in the broadcast message issued by the hub through the built-in I / O channel ...

Abstract

The invention discloses a method for achieving channel number identification of photoelectric directly-read wired remote gas meter. The method comprises the following steps that S1, an I/O channel of each gas meter connected with a hub is numbered, and I/O channel number information is stored in memorizers of the gas meters; S2, the hub issues broadcast messages to the gas meters, wherein the broadcast messages include I/O channel numbers of specified message receivers; S3, the gas meters receive the broadcast messages and extract the message receiver I/O channel numbers in the broadcast messages issued by the hub through I/O channel number extraction modules built in the gas meters; S4, I/O channel number identification modules built in the gas meters compare the message receiver I/O channel numbers extracted by the I/O channel number extraction modules with the I/O channel numbers of the gas meters themselves, receive the broadcast messages and execute corresponding operations if the I/O channel numbers are the same and do not execute operations if the I/O channel numbers are different. The method has an automatic identification function and can automatically identify channel numbers and facilitate automatic meter reading.

Description

technical field [0001] The invention relates to a photoelectric direct-reading gas meter, in particular to a method for realizing channel number identification of a photoelectric direct-reading wired remote transmission gas meter. Background technique [0002] The data collection of traditional gas meters relies on manual door-to-door data copying. The data collection process is time-consuming and laborious, and the accuracy and timeliness are difficult to guarantee. The following problems inevitably exist: there are errors in the copied data, which cannot truly reflect the user Actual gas consumption; it is difficult to standardize the operation, and it is easy to cause an increase in unknown losses; it consumes a lot of labor, high cost, and low efficiency. People urgently need to use modern technical means to solve the problems encountered in the meter reading work and improve the management level of gas consumption. [0003] In recent years, with the continuous developm...
