Data acquisition device and method based on Meter BUS

Abstract

The invention provides a data acquisition device and method based on a Meter BUS. The data acquisition device is an embedded instrument gateway, comprises a gateway CPU used for the instruction information to a Meter Bus sending module, controlling the implementation of the data acquisition work, and gathering and processing the data returned by a Meter BUS receiving module; the Meter Bus sendingmodule used for receiving the instruction information of the gateway CPU, converting the standard digital quantity data into the data conforming to a Meter BUS protocol and sending the data to an instrument end; and the Meter BUS receiving module which is used for receiving the data which is sent by the instrument end and conforms to the Meter BUS protocol, converting the data into the standard digital quantity data and transmitting the standard digital quantity data to the gateway CPU, and preferably comprises a Meter BUS protection module and a communication module. According to the device and the corresponding method, the normal and stable operation of a Meter BUS master station can be guaranteed through data sending, data receiving, overload protection and the like, an alarm is given in time when faults, such as overcurrent, etc., occur at any load node, the master station end devices are protected from being damaged, and the current technical blank is filled up.

Description

technical field [0001] The invention belongs to the field of industrial instrument data acquisition, relates to remote wireless / wired meter reading, and in particular to a Meter BUS-based data acquisition device and method. Background technique [0002] The traditional three meters (electricity meter, water meter, gas meter) require meter reading personnel to copy the data in person on a regular basis. This kind of meter reading method has large errors and heavy workload, and human errors will bring great inconvenience to related companies and users. The intelligent meter reading system is a technology that combines computer technology, modern communication technology, and embedded technology to realize remote reading and management of data from flow meters (electric meters, water meters, gas meters, etc.). The intelligent meter reading system realizes automatic data collection, timing transmission and real-time monitoring, which saves time, manpower and material resources a...

Problems solved by technology

[0005] The search found that on the instrument side, mainstream chip companies such as TI have complete integrated chip solutions; but the design of the master station side is more complicated than that of the instrument side. According to the current research, there is no open and complete solution on the market. Solutions, including the implementation of the master station in the form of integrated circuits, in order to achieve the transmission and processing of Meter BUS instrument terminal and master station information
