230M wireless collector

Abstract

The invention provides a 230M wireless collector. The 230M wireless collector mainly comprises a shell, a control chip, a 485 circuit, a power source and a 230M private network communication module, wherein the control chip, the 485 circuit, the power source and the 230M private network communication module are installed in the shell. The control chip is connected with an electric meter through the 485 circuit and 485 wires and directly conducts data interaction with the electric meter, real-time data are processed, and several freeze frame data are stored. The control chip is connected with the wired part of the 230M private network communication module through a serial port, the 230M private network communication module conducts interactive connection with a 230M base station through the wireless part, and the 230M base station is directly connected with a state grid main station. A state grid II type collector shell is adopted as the shell, and a sucker receiving antenna, an infrared communication hole, an indicator light hole, a wire RS485A, a line RS485B, a power line L and a power line N which are internally connected with the wireless part of the 230M private network communication module are arranged on the shell. The 230M wireless collector has the advantages that wiring is easy, and the 230M wireless collector can work in severer environments.

Description

technical field [0001] The invention relates to a wireless collector for collecting real-time electric energy indications, daily zero-point frozen electric energy indications, and daily zero-point frozen electric energy indications of meter reading meters. Background technique [0002] At present, the remote meter reading method based on the power carrier wave or the remote meter reading method based on the public network GPRS power private network is mainly used. The problems of carrier wave meter reading are mainly problems such as large interference and slow meter reading time. Remote meter reading based on GPRS public network will mainly generate certain traffic charges. Due to the huge number of electric meters, huge costs will be generated every month, and this The fee is paid year after year, and the final statistics are also a very large expense. Not only is it a tariff issue, but also a physical SIM card must be used to use GPRS. Since the SIM card has strict requi...

Problems solved by technology

[0004] First, the environment where the electric meter is located is complex, with different conditions such as smog, ultraviolet rays, and high and low temperature differences. At this time, the SIM card is prone to deformation, poor contact, or temperature out of range, which makes the communication equipment unable to work normally and affects the meter reading rate of the electrical equipment.

[0005] Second, the total amount of SIM is huge, the installation is scattered, the cost of fault maintenance is high, and the installation site is unattended, so it is easy to be stolen, which affects the reliability and safety of users' electricity consumption;

[0006] The third is that the SIM card itself is easily broken and physically damaged, which affects the use of the meter

[0008] 1. The number of SIM cards is huge, and the SIM cards cannot be

[0009] 2. On-site installation and replacement need to carry a large number of SIM cards, which are prone to mixed insertion and wrong insertion during installation, resulting in a mismatch with the terminal equipment and hindering normal communication
