Embodiment Construction

[0023] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein.

[0024] A high-efficiency meter reading method based on a routing table. In the method, the routing module uses a request reading method to perform meter reading, and includes the following steps:

[0025] 1. The routing module on the concentrator requests all the node addresses on a path to read the meter reading message that currently needs to be read, as the message sequence that the routing module requests to read this time;

[0026] 2. The routing module sends the reading frame through the physical layer link, and the downlink reading frame contains the message that all nodes on the path list request to...

Abstract

The invention discloses an efficient meter reading method based on a routing table. A routing module performs the meter reading by using a way of requesting to read, so that the module communication efficiency is effectively improved. The problem that the meter reading efficiency is low since the interactive delay between a concentrator and a routing module and between a sub-node module and a meter is solved. A meter reading address is decided by using the routing relation, the information required to read of all nodes on a reading path list can be simultaneously read through one-frame messagereading, and the communication efficiency and the meter reading efficiency are improved.

Description

Technical field [0001] The invention belongs to the field of low-voltage centralized reading, and specifically is a centralized reading method that realizes concurrent and efficient meter reading based on the routing relationship in the routing table. Background technique [0002] The invention is aimed at the field of low-voltage centralized copy broadband carrier communication. Compared with narrowband carrier, the invention has a higher communication rate, not less than 1Mbps, a larger data load, and a maximum support of 2046 bytes. During the meter reading process, it is subject to the timeout time of the meter serial port, and the request and response time during the interaction between the routing module and the concentrator. [0003] The traditional meter reading method is that the concentrator sends a frame of meter reading message. The routing module finds a reachable path according to the address to be read, and then uses this path to read. The relay node on the path rece...
