Problems solved by technology

Therefore, in practical applications, the amount of after-sales service is large, and the user's reputation for the product is not high; 2. It is difficult to ensure the accuracy of metering data sampling, and once the system data deviates, it cannot be compensated; 3. The sampling system is susceptible to interference and Attack; 4. The power consumption is large, and most of the meter controls are powered by batteries, and the batteries need to be replaced frequently
The existence of the above problems has affected the popularization and use of the control instruments of the existing control technology to a certain extent.

Embodiment Construction

[0021] Principle of the present invention: manual meter reading is the collection of the static data displayed by the meter counter. When the letters displayed on the counter wheel surface are all changed into binary state grids that can be judged according to their position and order, the grids are divided into reflective surfaces and light-absorbing surfaces. When a beam of light shines on the grid, there may be reflected light or no reflected light , passing this condition to the photocell can determine the state of the photocell. If there are four photoelectric cell outputs that determine the state, the value of the letter can be determined by the CPU. The counter is composed of a numerical word wheel to display the value of each bit. If each bit has four light beam outputs reflected by the wheel surface state, and there are four state light outputs, the counter data can be recognized bit by bit.

[0022] In order to enable the counter to display data to the user for comp...

Abstract

The present invention relates to a timing scanning acquisition system of optical fibre transmission static signal of metering device controller. The reliability of its control system can be greatly raised, and said control system can ensure uniform of metering data and sampling data. Said invention includes the following components: counter, display character wheel, synchronous wheel, four lines of light-emitting optical fibres, four lines of correspondent light-reflecting optical fibres, four photoelectric tubes, computer and luminotrons.

Description

1. Technical field: [0001] The invention relates to an acquisition system of a measuring instrument, in particular to a timing scanning acquisition system in which a measuring instrument controller transmits a static signal through an optical fiber. 2. Background technology: [0002] The collection of measurement data of traditional metering instruments (including gas meters, water meters, electric meters, heat meters, etc.) is realized by manual meter reading counter values. With the development of microelectronic technology, a controller combining electronic and mechanical instruments has appeared, using IC card or remote transmission to control the measurement data of the instrument. The sampling principle of this controller is a passive acquisition system of dynamic random signals. This system is widely used to use the rotating parts of the instrument and adopt the method of magnetic induction sensor sampling. When the instrument rotates, when the magnetic steel on the ...
