Data reading and transmitting device for wireless meter reading and low power consumption running method thereof

Abstract

The invention provides a low power consumption data reading and transmitting device based on a remote meter reading system of a heavy caliber water meter and a method for realizing low power consumption running. A power supply module (250) of the data reading and transmitting device (200) is provided with a miniature battery (251) electrically connected with a microprogrammed control unit MCU (210), an interface module (220) and a clock module (230) as well as a main power supply battery (252) electrically connected with a wireless transmitting module (240). An output power supply of the power supply module (250) is controlled through the microprogrammed control unit MCU (210), the microprogrammed control unit MCU (210) correspondingly works in a lower power consumption state and a normalworking state, and thus, the electric energy consumed by the data reading and transmitting device (200) is controlled. The invention solves the problem that the data reading and transmitting device (200) can also stably work for long term under the condition of using the battery as the power supply.

Description

technical field [0001] The invention relates to a data transmitting device and a method for reducing its power consumption, in particular to a low-power consumption data reading and transmitting device for remote wireless meter reading and a method for reducing its power consumption. Background technique [0002] With the continuous advancement of urbanization and the development of automation technology, the meter reading method of water meters has basically replaced manual meter reading by automatic meter reading. Wireless remote meter reading technology is the main way of automatic meter reading in the prior art. The existing wireless remote meter reading mainly adopts the following two methods: first, the GPRS collector meter reading method, that is, the pulse signal generated by the water meter is transmitted to the GPRS meter reading collector through the signal line, and the GPRS meter reading collector transmits the data wirelessly.

AI Technical Summary

Problems solved by technology

[0003] 1. For the data acquisition method of RF radio frequency transmission + handheld device, the RF radio frequency transmitter is limited in communication distance, and the handheld device usually needs to receive data within a range of about 100 meters

Since large-diameter water meters are mostly installed in the field and their locations are scattered, meter reading personnel need to hold a handheld mobile phone to read near the large-caliber water meter when reading the meter, which fails to achieve the purpose of automatic meter reading and increases the cost of meter reading;

[0004] 2. The GPRS collector requires long-term power supply of 220V mains, and large-caliber water meters are mostly installed in the field, and the relative positions of each meter are scattered, which makes the construction of power wiring difficult, and is not suitable for large-scale applications in water supply enterprises; if Using battery power supply, because the power consumption problem has not been solved, the stability of the meter reading system is reduced; therefore, the meter reading method of GPRS collectors powered by mains power is more used in water companies themselves, and their water meters are centrally installed in the factory area within 10 square kilometers to monitor water use
