Problems solved by technology
For the data transmission system in the device, these three actions will cause information transmission failure, and for the data transmission system with high sensitivity, the probability of data transmission failure is greater
Especially on the bus, it may take multiple actions to produce an "effective"; that is to say, the trigger in the radio frequency card --- the running path of the magnetic steel will affect the reliability of data transmission, which has long plagued the local Difficulties for field technicians

Embodiment Construction
[0012] The present invention as figure 1 , 2 As shown, it includes a reed switch 3, a data coil 2 and a housing 1. The top surface of the housing 1 is a working surface 10, and the bottom of the housing 1 is connected to the inside of the housing 1 and is perpendicular to the housing. The tube 11 on the working surface 10, the reed switch 3 is set upright in the lumen 12 of the tube 11, and the upward lead wire 32 of the reed switch 3 is bent by 90° and placed in the housing On the bottom surface of 1, the lead wire 2 31 facing downward of the reed switch 3 is set in the lumen 12 of 11. During the card swiping process of the radio frequency card 5, as long as the magnetic steel in the radio frequency card 5 attracts the horizontally arranged lead wire 32 on the top of the reed switch 3, the system can be started to work, and then the radio frequency card 5 must be able to effectively sense the data coil. information, so as to achieve the stability of data transmission.

The invention relates to a sensing device for a radio frequency card. The sensing device is not influenced by a triggering piece which enters a path and can realize data transmission with high reliability. The sensing device comprises a reed pipe, a data coil and a shell, wherein the top surface of the shell is an operating surface; a pipe which is communicated with the inner part of the shell and is vertical to the operating surface is arranged at the bottom of the shell; the reed pipe is vertically arranged in the pipe; and an upward lead wire 1 of the reed pipe is bent by 90 DEG and is then arranged on the bottom surface in the shell, and a downward lead wire 2 of the reed pipe is arranged in the pipe. In the sensing device, one lead wire of the reed pipe is bent by 90 DEG, the bent section is used as a receiving part of magnetic induction, and the other lead wire is away from the operating surface and is hidden behind. No matter from which square the radio frequency card approaches the operating surface and what feeding action is used, magnetic steel in the radio frequency can only generate the magnetic induction once on the bent part and trigger once. The sensing device can ensure that the communication of one-time data transmission can be triggered by approaching from any direction.
Description
technical field [0001] The invention relates to a radio frequency card sensing device, in particular to a radio frequency card sensing device in a low-power radio frequency card prepaid water meter and a bus IC card recording system. Background technique [0002] In order to improve the reliability of meters, in recent years, the share of low-power prepaid card-type water meters has gradually expanded. It uses the interaction between the radio frequency card with magnetic steel and the induction device to realize data exchange. That is, the action of the reed switch in the induction device is triggered by the magnetic steel, and the state is changed from the normally closed state to the open state, and then data exchange is performed. In the prior art, this kind of water meter has a working surface for "catering" to the radio frequency card, and the reed switch is placed below the working surface in parallel. It will trigger the reed switch to work, and then the meter will...
