Embodiment Construction

[0013] The specific embodiment of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] The bus mode remote gas collection system includes a main station computer, a concentrator connected to the main station computer, at least one collector, and at least one digital gas meter, the collector is connected to the concentrator, and the digital gas meter is connected to the collection device connection.

[0015] The concentrator is directly connected to the passive direct-reading gas meter through the communication bus. There are many options for communication bus, such as RS485 bus, M-BUS bus, CAN bus, short-distance wireless and other communication methods.

[0016] Compared with the above-mentioned communication methods, RS485 and M-BUS are more suitable for the centralized reading system of gas meters. Both RS485 and M-BUS buses use ordinary twisted-pair wires, and the wiring is simple and flexible according t...

Abstract

The invention relates to a bus-way remote gas meter centralized reading system. The bus-way remote gas meter centralized reading system comprises a master station computer, a concentrator which is connected with the master station computer, at least one collector and at least one digital gas meter, wherein the collector is connected with the concentrator, and the digital gas meter is connected with the collector. By adopting the bus-way remote gas meter centralized reading system, the construction amount is greatly reduced by utilizing an existing public communication network, and the system cost is maximally reduced. On the aspect of equipment, the modularization of communication units, the standardization of communication protocols and the normalization of the centralized reading equipment can be realized. Acquired data are accurately uploaded to a master station through a wireless network.

Description

technical field [0001] The invention belongs to the field of computer software, and in particular relates to a remote gas collection system in the form of a bus. Background technique [0002] The main function of the centralized reading system is to automatically transmit the data of the gas meter to the main station within a certain period of time (every day or every month). This system is mainly composed of a gas meter, centralized reading equipment, and a master station. The gas meter is responsible for measurement, and the centralized reading equipment is responsible for reading the data of the gas meter and transmitting it to the main station. The main station performs data analysis, output report, and docking with the marketing system. The master station must also have a certain ability to judge problems, and make corresponding marks or alarms. [0003] The existing gas meter reading method relies on manual implementation, which is time-consuming and laborious, and n...
