Detailed Description

The technical solutions of the embodiments of the present utility model will be explained and illustrated below with reference to the drawings of the embodiments of the present utility model, but the following embodiments are only preferred embodiments of the present utility model, and not all embodiments. Based on the examples in the implementation manner, other examples obtained by a person skilled in the art without making creative efforts fall within the protection scope of the present utility model.

In the following description, directional or positional relationships such as the terms "inner", "outer", "upper", "lower", "left", "right", etc., are presented for convenience in describing the embodiments and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the utility model.

The embodiment provides a battery compartment with a cover-opening report, which is installed in a gas meter as shown in fig. 1 and comprises a compartment body 1 and a cover body 2, wherein the cover body 2 is rotatably connected with the compartment body 1 and can be opened or closed.

The hall detection circuit board 11 is installed on the cabin body 1, the magnetic piece 21 is installed on the cover body 2, the hall detection circuit board 11 is provided with a hall element, and the hall element works by using the hall effect. The hall effect is one of the electromagnetic effects, and when a current is passed through a semiconductor perpendicular to an external magnetic field, carriers are deflected, creating an additional electric field perpendicular to the direction of the current and magnetic field, thereby creating a potential difference across the semiconductor. Therefore, when carriers in the solid material move in an externally applied magnetic field, the tracks deviate due to the action of Lorentz force, charge accumulation is generated on two sides of the material, an electric field perpendicular to the current direction is formed, and the Lorentz force applied to the carriers is balanced with the repulsive force of the electric field, so that a stable potential difference, namely Hall voltage, is established on two sides.

Specifically, this embodiment further provides an implementation of the structure of the hall detection circuit board 11, as shown in fig. 2, where the hall detection circuit board 11 in this embodiment includes a first capacitor, a hall element, a second capacitor, and a 3Pin connection terminal, and the 3Pin connection terminal includes an uncap signal output Pin, a ground Pin, and a power supply Pin.

When the cover 2 is closed, the distance between the magnetic member 21 and the hall element is small, and the magnetic field sensed by the hall element is strong. When the cover 2 is opened, the cover 2 is separated from the cabin 1 by rotation, the magnetic member 21 moves away from the hall element along with the cover 2, the magnetic field sensed by the hall element is weak, the generated hall voltage changes, and the hall detection circuit board 11 generates and sends out the cover opening signal.

When the cover body 2 is opened, the distance between the magnetic piece and the Hall element is increased or decreased, and the output current of the Hall element is changed, so that the Hall detection circuit board sends out a cover opening signal.

As a more specific implementation, the magnetic member 21 and the hall element on the hall detection circuit board 11 are disposed at opposite positions on the cover 2 and the case 1, and when the cover 2 is closed in the battery case, the magnetic member 21 is attached to the hall element, so that the hall element has the most sensitive detection effect for opening the cover 2.

As a more specific implementation, the magnetic member 21 is a magnetic bead, and the Hall element is an S-5712ACDL1 Hall sensor.

When the cover body is opened, the magnetic field change of the battery compartment disclosed by the utility model can trigger the Hall element immediately to generate a cover-opening signal, and the gas meter immediately reports the cover-opening state. The battery compartment and the gas meter are still in the power-on state after the cover body is opened because the battery compartment is not informed when the power is cut off, and the battery compartment and the gas meter can be informed again if the previous informing fails due to accidental factors, so that the reliability of the informing communication is improved. And the time for reporting can be advanced by detecting the open cover reporting through the Hall element, so that the capacitor with a lower capacitance value can be adopted, the early warning reliability is successfully improved, and the production cost and the development cost are reduced.

In one embodiment, the structure schematic diagram of the gas meter is shown in fig. 1, the circuit connection schematic diagram is shown in fig. 3, and the battery compartment for covering the cover according to the embodiment further comprises a main control board, wherein the main control board is provided with a power circuit, an MCU, a communication module power supply circuit and a communication module;

In the structure, the cover opening detection circuit is arranged on the Hall detection circuit board, and the cover opening detection function is mainly realized by the Hall device. The power supply circuit continuously supplies power to the MCU and the Hall detection circuit board, and intermittently supplies power to the communication power supply circuit, and the power supply time is controlled by the MCU. After the Hall detection circuit board generates a cover opening signal, the signal is transmitted to the MCU, the MCU generates a power on signal of the power supply circuit of the communication module, the power supply circuit supplies power to the communication module at the moment, and the MCU and the communication module perform signal interaction, so that a cover opening and reporting function is realized, and meanwhile, the current air quantity is reported.

The Hall detection circuit board is connected with the main control board through 3Pin binding post, and 3 connecting wires of 3Pin binding post are the signal line respectively, ground wire and power cord, draw forth uncapping signal output Pin, ground Pin and power supply Pin.

The hall device appears high when no magnetic field is induced and the voltage is pulled low when a magnetic field is induced. When the battery cover is not opened, the MCU is in low level corresponding to the IO port, when the cover opening operation is carried out, the positions of the magnetic beads are changed, the magnetic field is changed, the level is pulled up, the level change (cover opening signal) from low level to high level exists, when the MCU receives the level change, a power supply opening signal of a power supply circuit of the communication module and a reporting signal of the communication module are sent, and the communication module is opened and the reporting operation is carried out.

The above is only a specific embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and it should be understood by those skilled in the art that the present utility model includes but is not limited to the accompanying drawings and the description of the above specific embodiment.
