Data collection device of intelligent metering device

Abstract

The invention discloses a data collection device of an intelligent metering device. The data collection device of the intelligent metering device is stable and reliable in performance, accurate in sensing data, easy to manufacture and low in cost. The data collection device of the intelligent metering device comprises a character wheel box (1), a plurality of character wheels (2), electric conduction elastic pieces (4) and a circuit board (5), wherein resistive electric conduction strips (3) are arranged in the circumferences of the wheel faces of the character wheels (2); the conduction elastic pieces (4) make sliding contact with the resistive electric conduction strips (3) all the time through elasticity to achieve electric connection; resistive loops in fixed electric conduction connection are formed between the conduction elastic pieces (4) and the circuit board (5); when the character wheels (2) are located at different positions, the contact electric conduction positions of the conduction elastic pieces (4) and the resistive electric conduction strips (3) are different, so that the values of resistance between the loops of the conduction elastic pieces (4) and the circuit board (5) are different, a mapping relation is formed between a display value corresponding to the different rotation positions of the character wheels (2) and the current in the loops, the display digit positions of the character wheels (2) are obtained by collecting the current of the loops, and then the reading information of the character wheels (2) is obtained. The data collection device of the intelligent metering device can be applied to the field of intelligent metering devices.

Description

technical field [0001] The invention relates to a data acquisition device of an intelligent measuring instrument. Background technique [0002] With the development of urban intelligence and the popularization of the Internet of Things, there are now smart water meters, smart electricity meters, smart gas meters and smart heating meters that can remotely transmit data and realize remote control. This type of smart metering instrument requires a numerical collector with the function of displaying data, and can convert the displayed data into digital signals, and then transmit the data signals far away. [0003] The Chinese patent application number is 201110274440.2, which discloses a direct-reading water meter, which includes a digital wheel, a housing, and a carry wheel. The carry wheel is installed on the bottom or side of the digital wheel, and each digital wheel is inlaid or Coated with the material corresponding to the sensor, install 2 to 3 sensors to identify the dig...

Problems solved by technology

It has the following shortcomings and deficiencies: the painted color has an attenuation cycle that changes with time, and the painted color is easy to fall off after being soaked in the liquid for a long time, thus affecting the accuracy of data collection; Complex process and high manufacturing cost

[0004] In addition, there are currently three types of different light and dark reflective surface areas for the ten display numbers on the character wheel surface, thereby forming a data acquisition scheme with different codes for reflected light. The printing process requires high requirements, high cost, and low stability. The aging of electronic components will affect data acquisition and cause confusion, and the requirements for electronic components are high.
