Micro-power wireless meter reading method

Abstract

The invention discloses a micro-power wireless meter reading method. The method comprises the following steps: (1) when a concentrator starts to read a meter, the concentrator selects a route to carry out networking; (2) during the networking process, the central node judges whether the routing table contains an undetected route for the sub-node or not in advance; if the answer is positive, the central node judges whether a route, which has been successfully detected in the previous related business of the sub-node, exists in the undetected routes, if the answer is negative, the previous used route is chosen and used to detect the nodes; and if the answer is positive, the undetected rout with the highest weight is chosen and used to detect the nodes; (4) the detection is judged, if the detection is success, the route used in this communication is checked to judge whether the used rout has been reserved in the routing table or not, if the route has been reserved, the weight of the route is updated; and if the rout has not been reserved in the routing table, the route is used to replace the route with the smallest weight in the routing table; (5) if the route detection is success, the routing meter reading is started. The automatic maintenance effect is good, and wireless meter reading is achieved.

Description

technical field [0001] The invention belongs to the micro-power wireless meter reading technology and relates to a micro-power wireless meter reading method. Background technique [0002] With the rapid development of scientific application technology, in the field of electric meter reading, there have been a variety of meter reading schemes coexisting, such as traditional manual meter reading, leased telephone line meter reading, low-voltage power carrier meter reading, optical fiber meter reading, etc. But these meter reading methods all have their own defects. The traditional way of meter reading is to manually copy the energy meter data from door to door, which will inevitably lead to inaccurate statistical data and cannot truly reflect the electricity consumption of users; it is difficult to standardize the operation, resulting in increased unknown losses; and it consumes a lot of labor, high cost and low efficiency . Obviously, the manual meter reading management mod...

Problems solved by technology

However, in practical applications, due to various reasons, some node routes fail or cannot communicate with the node through the routing path

At this time, the use of route meter reading is failed
