Wireless split-type metering device

Abstract

The disclosed wireless split meter comprises: a micro-controller, a meter module, an AC-DC power, a RF transmitting-receiving module, a cell, a hardware clock, a SAM module, and an indicator lamp; wherein, the former four items are necessary; or, forming a user interface device by a micro-controller, a LCD module, an AC-DC power,, a cell, a RF transmitting-receiving module, an IC interface, the press-key, and buzzer for common interface device with the former five items necessary. Wherein, it is fit to use a short-distance dual wireless communication between the calculation control device and user interface.

Description

technical field [0001] The invention belongs to the field of metering instruments and their applications, and in particular relates to a wireless split meter device, including ordinary electromechanical or fully electronic water, electricity, gas and heat meters and IC meters with single or multiple rates. Card (prepaid or controlled postpaid) for water, electricity, gas and heat meters. Its feature is that the function of the meter is divided into two parts: the "metering control device" with safety protection requirements and the "user interface device" without safety protection requirements. Science Medicine) frequency band RF Transceiver (RF Transceiver) module for short-distance two-way data communication. Background technique [0002] Water meters, electric meters, gas meters and heat meters (hereinafter collectively referred to as meters) are commonly used measuring instruments in people's daily life. The traditional water, electricity, and gas meter is a mechanical...

Problems solved by technology

[0012] (1) Due to the LED or LCD display window of the electronic meter, and the card slot of the IC card meter, especially the contact IC card meter, it is difficult to be strictly sealed. Conditions are more sensitive;

[0013] (2) Since electricity meters including IC card meters are usually placed in public spaces such as corridors, they are easily accessed by the outside world, and electricity theft such as bypass and grounding and other malicious attacks and damages occur, including charging into the IC card port. Dozens of methods of attack and sabotage, such as pouring water, inserting iron sheets, and shocking with high-voltage igniters, and it is difficult for the management to catch these attackers and saboteurs

In addition to the use of inlet bushings and meter boxes, there is currently no other better protection

On the one hand, these man-made attacks and sabotages have caused a large cost leakage, and on the other hand, they have also significantly increased the cost of equipment installation, maintenance and management

[0014] (3) The current common electronic meters usually use LED digital or LCD liquid crystal display, LED display relatively high power consumption and insufficient information, and LCD display has problems in low temperature and brightness

Although LCD display is a developmen
