Description
Technical field
The utility model relates to a kind of line of electric force meter copying device, especially relates to a kind of wireless low-voltage power line meter copying device based on the RS485 electric energy meter.
Background technology
At present, the existing power meter reading method mainly contains several kinds of following modes: take the form of manual metering, promptly show according to gauge outfit and check meter; Take hand-held infrared copying instrument to check meter, generally speaking, hand-held infrared copying instrument is checked meter, and it is a single-chip computer control system that has infrared receiving/transmission, and electric energy meter should be provided with corresponding functions of receiving and transmitting infrared for this reason; Far distance automatic kilowatt meter reading-out system, under this kind form, managerial personnel can be sitting in the office, use microcomputer through passages such as netting twines, check meter and the management of power use.Yet existing these meter reading methods and system establish each owing to will increase independent network, therefore, have certain shortcoming inevitably.
WSN (Wireless Sensor Networks wireless sensor network) is the common name of a series of micropower mechanicss of communication; In low-power consumption, cheaply under the prerequisite; WSN utilizes high speed microprocessor technology to solve a communication difficult problem, the application that is suitable for that measurement point is many, the low pressure of scope dispersion occasion is checked meter.
Summary of the invention
The purpose of the utility model is exactly for the defective that overcomes above-mentioned prior art existence the wireless low-voltage power line meter copying device based on the RS485 electric energy meter that a kind of installation cost is low, not influenced by the line of electric force topological network to be provided.
The purpose of the utility model can realize through following technical scheme:
A kind of wireless low-voltage power line meter copying device based on the RS485 electric energy meter; This device comprises radio concentrator, wireless collection device, RS485 electric energy meter and total ammeter; Described RS485 electric energy meter is connected with the wireless collection device through the RS485 bus; Described wireless collection device is connected with radio concentrator through wireless network, and described total ammeter connects radio concentrator.
The input end of described wireless collection device is provided with 485 mouthfuls, and output terminal is provided with the radio communication mouth, and described 485 mouthfuls are connected with the RS485 electric energy meter through the RS485 bus, and described radio communication mouth is communicated by letter with radio concentrator and is connected.
Described wireless collection device connects a plurality of RS485 electric energy meters and connects.
Also comprise wireless repeater in the described device, described wireless repeater is arranged between wireless collection device and the radio concentrator.
Compared with prior art, the utlity model has following advantage:
1) real-time of wireless network is good, and speed is higher, is convenient to realize demanding value-added service of real-time such as long-range pre-payment etc.;
2) self-organizing network can be sought all radio nodes in the radio-frequency region, does not receive the influence of line of electric force topological network;
3) need not wiring, installation cost is low;
4) wireless module on concentrator under the situation that remote channel lost efficacy, can be met an urgent need and the on-the-spot function of checking meter of wireless handheld meter reading terminal realization, and speed is fast, uses more convenient.
