Embodiment Construction

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the intended invention purpose, the specific implementation, structure, features and effects of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0024] refer to figure 1 , which is a schematic diagram of the smart meter acquisition system 100 provided by the embodiment of the present invention. Such as figure 1 As shown, the smart meter acquisition system 100 includes: a host 10 and a plurality of smart meters 20 . The host 10 and the smart meter 20 can be connected by a serial communication bus (for example, RS485 serial communication bus).

[0025] But in terms of specific cable connection, the connection between the host 10 and the smart meter 20 may not use a traditional serial port connection line, but may use an 8-core cable (generally used for a network cable) to connect, and pr...

Abstract

The invention relates to an automatic address allocation serial port ammeter acquiring method. The method comprises the following steps that a host monitors signals input by a plurality of I / O (Input / Output) ports after being started; an ammeter is connected to one of the plurality of I / O ports through an address line after being started, transmits a connection signal, and intercepts an address signal transmitted by the host; the host acquires an allocated address after detecting the connection signal, returns the address to the ammeter, delays for predetermined time and transmits a handshake signal to the allocated address through a communication bus; the ammeter initializes the communication bus after receiving the address returned by the host, starts to intercept the handshake signal transmitted by the host, and returns to identity verification information of the ammeter after receiving the handshake signal transmitted by the host; the host verifies the identity of the ammeter according to the identity verification information, and finishes the allocation of a communication address if the identity verification succeeds. By adopting the method, automatic allocation of a serial communication bus address can be realized. Moreover, the invention further provides a smart ammeter acquiring system based on a serial communication bus.

Description

technical field [0001] The invention relates to communication technology, in particular to a method for collecting serial electric meters with automatic address assignment and an intelligent electric meter collection system. Background technique [0002] With the increasing development and improvement of domestic intelligent systems, remote meter reading systems have been installed in most high-end residential quarters. As an important part of the modern management system, the system has played a very important role. Meters such as water meters, electricity meters, and gas meters in each household in a residential area. Its installation location is different, and some meters (as electric meter) are installed in a centralized manner, but some meters (as water meter) are scattered in households; this just brings difficulty to the meter reading statistics work of management department. It takes a lot of manpower and time to read the meter door by door, and it is difficult to c...
