Remote meter reading method, remote meter reading system and intelligent electric energy meter

Abstract

The invention discloses a remote meter reading method, a remote meter reading system and an intelligent electric energy meter, wherein the remote meter reading method comprises the steps that a collection terminal sends a meter reading command to the intelligent electric energy meter by a route server in a Z-Wave network, wherein the meter reading command includes an intelligent electric energy meter address and electric energy meter data item information; after receiving the meter reading command, the intelligent electric energy meter judges whether the intelligent electric energy meter address in the meter reading command is identical with the self electric energy meter address of the intelligent electric energy meter, if so, the intelligent electric energy meter conducts statistics on electric energy meter data according to the electric energy meter data item information; and the intelligent electric energy meter sends the electric energy meter data to the collection terminal by the route server. The Z-Wave network does not rely on a mobile network of an operator, thus facilitating installation, and being capable of reducing the meter reading cost while increasing the meter reading speed.

Description

technical field [0001] The invention relates to the communication field, in particular to a remote meter reading method and system, and a smart meter. Background technique [0002] At present, the technologies used for meter reading mainly include manual meter reading, RS485 bus meter reading, and wireless meter reading. Due to the poor timeliness of manual meter reading, large statistical workload, and high cost of meter reading, manual meter reading is gradually being replaced by RS485 bus meter reading and wireless meter reading. At present, the meter reading method of RS485 bus is relatively mature, and there is a relatively complete implementation system in terms of maintenance and construction. However, the shortcomings of the RS485 bus meter reading method are also obvious, that is, the wiring is relatively complicated, and the maintenance cost is high. For places where wiring is difficult, this meter reading method is difficult to use. The current wireless meter re...

However, the shortcomings of the RS485 bus meter reading method are also obvious, that is, the wiring is more complicated and the maintenance cost is high. For places where wiring is difficult, this meter reading method is difficult to use

The current wireless meter reading method mainly utilizes the existing General Packet Radio Service (GPRS for short), Global System of Mobile Communication (GSM for short) or other third-generation mobile communication technologies ( 3 rd Generation, referred to as: 3G) network, the disadvantage of this method is that it needs to rely on the operator's mobile network, so it needs to pay high traffic fees to the mobile operator, resulting in higher operating costs

At the same time, in remote areas, due to the poor infrastructure of mobile operators, the success rate of meter reading is low
