Description

Technical Field

[0001] This invention relates to the field of magnetic induction integrated circuits, and particularly to a bipolar magnetic induction integrated circuit and switch. Background Technology

[0002] Existing magnetic induction integrated circuits are generally unipolar magnetic induction integrated circuits. Switches using unipolar magnetic induction integrated circuits have the following disadvantages: 1. Unipolar magnetic induction integrated circuits generally use unipolar Hall effect sensors, which only respond to a single magnetic pole (usually the S or N pole), and the other pole has no response, resulting in low flexibility; 2. Unipolar Hall effect sensors may be falsely triggered by interference from a single magnetic pole, resulting in weak anti-interference capability. Summary of the Invention

The sequence number of the bipolar magnetic induction integrated circuit on the PCB is written into the address code of the corresponding integrated circuit chip. The data information code period sequence number sent by the MCU after the address code corresponds one-to-one with the sequence number of the bipolar magnetic induction integrated circuit on the PCB.

[0011] The bipolar magnetic induction integrated circuit contains a programmable address code and integrates a bipolar magnetic induction circuit and a GRB color driving circuit.

[0012] The bipolar magnetic induction integrated circuit includes a power supply pin and a ground pin. The power supply pin is used to power the bipolar magnetic induction integrated circuit and transmit information, while the ground pin is used for signal grounding and power grounding. The power supply pins of n bipolar magnetic induction integrated circuits are connected in parallel to share the power network VCC and are connected to the MCU. The ground pins are connected in parallel to share the ground network GND. The data information of the bipolar magnetic induction integrated circuit is modulated on the power network VCC for transmission. The sequence number of the bipolar magnetic induction integrated circuit on the PCB is written into the address code of the corresponding bipolar magnetic induction integrated circuit. The data information code period sequence number sent by the MCU after the address code corresponds one-to-one with the sequence number of the bipolar magnetic induction integrated circuit on the PCB.

[0013] The bipolar magnetic induction integrated circuit contains a programmable address code, and the bipolar magnetic induction integrated circuit only integrates a bipolar magnetic induction circuit.

[0014] The bipolar magnetic induction integrated circuit includes a power supply pin, a ground pin, and a data pin. The power supply pin is used to power the bipolar magnetic induction integrated circuit, and the ground pin is used for signal grounding and power grounding. The power supply pins of n bipolar magnetic induction integrated circuits are connected in parallel to share a power network VCC, the ground pins are connected in parallel to share a ground network GND, and the data pins are connected in parallel to share a data line network DIO and are connected to the MCU. The data information of the bipolar magnetic induction integrated circuit is modulated on the data line network DIO for transmission. The sequence number of the bipolar magnetic induction integrated circuit on the PCB is written into the address code of the corresponding bipolar magnetic induction integrated circuit. The data information code period sequence number sent by the MCU after the address code corresponds one-to-one with the sequence number of the bipolar magnetic induction integrated circuit on the PCB.

[0015] The bipolar magnetic induction integrated circuit contains a programmable address code, and the bipolar magnetic induction integrated circuit only integrates a bipolar magnetic induction circuit.

[0016] The bipolar magnetic induction integrated circuit includes a power supply pin and a ground pin. The power supply pin is used to power the bipolar magnetic induction integrated circuit and transmit information, while the ground pin is used for signal grounding and power grounding. The power supply pins of n bipolar magnetic induction integrated circuits are connected in parallel to share a power network VCC and are connected to the MCU. The ground pins are connected in parallel to share a ground network GND. The data information of the bipolar magnetic induction integrated circuit is modulated on the power network VCC for transmission. The sequence number of the bipolar magnetic induction integrated circuit on the PCB is written into the address code of the corresponding bipolar magnetic induction integrated circuit. The data information code period sequence number sent by the MCU after the address code corresponds one-to-one with the sequence number of the bipolar magnetic induction integrated circuit on the PCB.

[0017] The address code of the bipolar magnetic induction integrated circuit has several bits. When n bipolar magnetic induction integrated circuits with address codes are connected in parallel, the initial address code of the bipolar magnetic induction integrated circuit is reprogrammed by a custom address code instruction. The sequence number of the bipolar magnetic induction integrated circuit on the PCB is written into the address code of the corresponding bipolar magnetic induction integrated circuit. The operation on the address code of the bipolar magnetic induction integrated circuit is the operation on the bipolar magnetic induction integrated circuit corresponding to the address code. Each bipolar magnetic induction integrated circuit also corresponds to a button, so the operation on the address code of the bipolar magnetic induction integrated circuit is the operation on the button corresponding to the bipolar magnetic induction integrated circuit.

[0018] The address code of the bipolar magnetic induction integrated circuit has n bits, and the bipolar magnetic induction integrated circuit also has its own identification code UID. After the custom address code instruction reads the UID code, it writes this UID code along with a natural sequence code to be set into the bipolar magnetic induction integrated circuit. After the bipolar magnetic induction integrated circuit compares this UID code with its own UID code and finds that they are correct, it stores the corresponding sequence bit of the bipolar magnetic induction integrated circuit into the address code. The operation on the address code of the bipolar magnetic induction integrated circuit is the operation on the bipolar magnetic induction integrated circuit corresponding to the address code. Each bipolar magnetic induction integrated circuit also corresponds to a button, so the operation on the address code of the bipolar magnetic induction integrated circuit is the operation on the button corresponding to the bipolar magnetic induction integrated circuit.

[0019] The address codes of the bipolar magnetic induction integrated circuits are fused together using laser fusing technology to fuse the initial address codes of n bipolar magnetic induction integrated circuits, thus changing their address codes into their sequence positions on the PCB. Operations on the address codes of the bipolar magnetic induction integrated circuits are operations on the corresponding bipolar magnetic induction integrated circuits. Each bipolar magnetic induction integrated circuit corresponds to a button, so operations on the address codes of the bipolar magnetic induction integrated circuits are operations on the corresponding buttons.

[0020] n bipolar magnetic induction integrated circuits are cascaded together and then connected to the MCU.

[0021] The bipolar magnetic induction integrated circuit is either a bipolar latch-type bipolar magnetic induction integrated circuit or a bipolar non-latch-type bipolar magnetic induction integrated circuit.

[0022] The bipolar magnetic induction integrated circuit is a bipolar Hall magnetic induction integrated circuit, or a bipolar TMR, or a bipolar AMR, or a bipolar GMR.

[0023] Another objective of this invention is achieved through the following technical solution:

[0025] The switch can be applied to mice, keyboards, liquid level sensors, electronic Go sets, and toys.

[0026] A switch employs the aforementioned bipolar magnetic induction integrated circuit to directly output high and low levels when the induced magnetic poles change.

[0027] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0028] 1. The bipolar magnetic induction integrated circuit of the present invention operates by detecting changes in the direction of the magnetic field, and has stronger anti-interference ability against stray magnetic fields (it requires a specific polarity change to trigger) and stronger anti-interference ability.

[0029] 2. The bipolar magnetic induction integrated circuit of this invention can detect magnetic fields at both the north and south poles (both N and S poles are triggered), making it suitable for scenarios that require distinguishing magnetic field polarity (such as motor commutation and position detection), and providing more flexible detection of magnetic field direction.

[0030] 3. The bipolar magnetic induction integrated circuit of this invention is more suitable for dynamic control and frequent high and low level switching.

[0031] 4. The bipolar magnetic induction integrated circuit of this invention has a high degree of functional integration.

[0038] 1-First magnetic element. Detailed Implementation

[0039] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0040] Example 1

[0041] A bipolar magnetic induction integrated circuit, each bipolar magnetic induction integrated circuit corresponding to a push-button switch, each push-button switch including a switch body and a magnetic element; the switch body includes a vertically movable component, the bipolar magnetic induction integrated circuit is disposed on the surface of a PCB board, and the magnetic induction direction of the bipolar magnetic induction integrated circuit is vertical; the magnetic element is located above the side of the bipolar magnetic induction integrated circuit and disposed on the vertically movable component.

[0042] And the N and S poles of the magnetic element are perpendicular (e.g.) Figure 1 , 2 The magnetic element moves up and down on the horizontal plane of the vertical bipolar magnetic induction integrated circuit.

[0043] The magnetic parameters BOP and BRP code values ​​of the bipolar magnetic induction integrated circuit are programmable. By setting the BOP and BRP code values, the on-stroke and off-stroke of the push-button switch can be set; the magnetic induction polarity of the bipolar magnetic induction integrated circuit is also programmable.

[0044] BOP stands for Operating Point, which refers to the minimum magnetic field strength required for a Hall switch to begin conducting under magnetic influence.

[0045] BRP stands for Release Point, which refers to the maximum magnetic field strength at which a Hall switch closes under magnetic influence.

[0046] Figure 1 ,2 This can be explained by the magnetic induction principle that when the N and S poles of a magnetic element are perpendicular, the magnetic element moves up and down on the horizontal plane of the magnetic induction of the bipolar magnetic induction integrated circuit.

[0047] A bipolar magnetic induction integrated circuit is one that conducts when a magnetic pole is near it and continues to conduct when it is away, and only turns off when another magnetic pole is applied to it. Figure 1 , 2 In the process, the magnetic element moves up and down on the magnetic induction plane of the bipolar magnetic induction integrated circuit. The transition from the induction polarity of the bipolar magnetic induction integrated circuit and the polarity of the magnetic element being inconsistent to the induction polarity of the bipolar magnetic induction integrated circuit and the polarity of the magnetic element being consistent all satisfy the characteristics of the bipolar magnetic induction integrated circuit being turned on and off.

[0048] The specific working process is as follows:

[0049] First, the output is set to low level when the induction polarity of the bipolar magnetic induction integrated circuit and the induction polarity of the magnetic element are the same, and to high level when the induction polarity of the bipolar magnetic induction integrated circuit and the induction polarity of the magnetic element are different.

[0050] Then, as Figure 1 The magnetic element is above the magnetic induction plane of the bipolar magnetic induction integrated circuit. At this time, the N pole of the magnetic element is close to the S pole of the bipolar magnetic induction integrated circuit, and the bipolar magnetic induction integrated circuit is turned off and outputs a high level.

[0051] Next, the magnetic element continues to move downwards, passing through the magnetic induction horizontal plane of the bipolar magnetic induction integrated circuit (such as...). Figure 2 When the N pole of the magnetic element just passes through the magnetic induction plane of the magnetic induction integrated circuit, the N pole of the magnetic element is close to the N pole of the magnetic induction integrated circuit, and the S pole of the magnetic element is close to the S pole of the magnetic induction integrated circuit. The bipolar magnetic induction integrated circuit is turned on and outputs a low level. (When the magnetic element continues to move downward to the lowest position, the top of the magnetic element is always higher than the magnetic induction plane of the bipolar magnetic induction integrated circuit).

[0052] Then, Figures 2 to 1 During the reset process, the bottom of the magnetic element is higher than the magnetic induction plane of the bipolar magnetic induction integrated circuit, and the polarity is relatively reversed. The bipolar magnetic induction integrated circuit turns off and outputs a high level.

[0053] We can also configure the output to be high when the polarity of the bipolar magnetic induction integrated circuit is the same as that of the magnetic element, and to be low when the polarity of the bipolar magnetic induction integrated circuit is different from that of the magnetic element.

[0054] Several (greater than or equal to 2) bipolar magnetic induction integrated circuits are connected in parallel. The bipolar magnetic induction integrated circuit contains a programmable address code and integrates a bipolar magnetic induction circuit and a GRB color driving circuit.

[0055] The bipolar magnetic induction integrated circuit includes power supply pins, ground pins, and data pins. The power supply pins are used to power the bipolar magnetic induction integrated circuit, and the ground pins are used for signal grounding and power grounding. The power supply pins of n bipolar magnetic induction integrated circuits are connected in parallel to share the power network VCC, the ground pins are connected in parallel to share the ground network GND, and the data pins are connected in parallel to share the data line network DIO and are connected to the MCU. The data information of the bipolar magnetic induction integrated circuit is modulated on the data line network DIO for transmission. The sequence number of the bipolar magnetic induction integrated circuit on the PCB is written into the address code of the corresponding integrated circuit chip. The data information code period sequence number sent by the MCU after the address code corresponds one-to-one with the sequence number of the bipolar magnetic induction integrated circuit on the PCB.

[0056] In other words: the T1 time period sequence of the data information code period 1 sent by the MCU after the address code corresponds to the bipolar magnetic induction integrated circuit at position 1 on the PCB; the T2 time period sequence of the data information code period 2 sent by the MCU after the address code corresponds to the bipolar magnetic induction integrated circuit at position 2 on the PCB; and the T3 time period sequence of the data information code period 3 sent by the MCU after the address code corresponds to the bipolar magnetic induction integrated circuit at position 3 on the PCB.

[0057] For example, such as Figure 5Three bipolar magnetic induction integrated circuits with address codes are connected in parallel to form a row, creating a VCC network, a ground GND network, and a data line DIO network; all networks with the same name are electrically connected. The three bipolar magnetic induction integrated circuits with address codes are numbered sequentially from left to right in the coordinate system as sequence 1, sequence 2, and sequence 3. The first magnetic element 1 moves above each bipolar magnetic induction integrated circuit with address codes in a custom sequence from beginning to end. When the first magnetic element 1 moves above sequence 1, sequence 1 bipolar magnetic induction integrated circuit senses a voltage change through magnetic induction. Simultaneously, sequence 1 bipolar magnetic induction integrated circuit receives an address code instruction and address code 1, then saves the number 1 as the address code. Next, when the first magnetic element 1 moves above sequence 2, sequence 2 bipolar magnetic induction integrated circuit senses a voltage change through magnetic induction, and simultaneously... When the integrated circuit receives an address code instruction and address code 2, it saves the number 2 as the address code. When the first magnetic element 1 is moved above the bipolar magnetic induction integrated circuit at position 3, the bipolar magnetic induction integrated circuit at position 3 senses the voltage change through magnetic induction. At the same time, the bipolar magnetic induction integrated circuit receives an address code allocation instruction and address code 3, and saves the number 3 as the address code. In this way, we have completed the regular natural sequence address code for the bipolar magnetic induction integrated circuits at positions 1, 2, and 3. The natural sequence address code greatly facilitates information communication. The same applies to n bipolar magnetic induction integrated circuits.

[0058] The address code of the bipolar magnetic induction integrated circuit has several bits. When n bipolar magnetic induction integrated circuits with address codes are connected in parallel, the initial address code of the bipolar magnetic induction integrated circuit is reprogrammed by a custom address code instruction. The sequence number of the bipolar magnetic induction integrated circuit on the PCB is written into the address code of the corresponding bipolar magnetic induction integrated circuit. The operation on the address code of the bipolar magnetic induction integrated circuit is the operation on the bipolar magnetic induction integrated circuit corresponding to the address code. Each bipolar magnetic induction integrated circuit also corresponds to a button, so the operation on the address code of the bipolar magnetic induction integrated circuit is the operation on the button corresponding to the bipolar magnetic induction integrated circuit.

[0059] Example 2

[0060] Except for the following content, which differs from that of Example 1, this embodiment is otherwise identical to Example 1:

[0061] The N and S poles of a magnetic element are oriented horizontally (e.g., Figure 3 , 4The magnetic element moves vertically up and down along the magnetic induction plane of the bipolar magnetic induction integrated circuit. When the magnetic element is stationary, it is located above one side of the bipolar magnetic induction integrated circuit. As the magnetic element moves up and down, it passes through the opening on the PCB and reciprocates vertically along the magnetic induction plane of the bipolar magnetic induction integrated circuit, causing the bipolar magnetic induction integrated circuit to close or open. During the up and down movement, the magnetic element always remains parallel to the horizontal plane of the bipolar magnetic induction integrated circuit, either on the opposite plane or on the same plane. When the magnetic element is parallel to the horizontal plane of the bipolar magnetic induction integrated circuit, the N or S pole of the magnetic element is directly opposite the horizontal plane of the bipolar magnetic induction integrated circuit.

[0062] Figure 3 , 4 This can be explained by the magnetic induction principle that when the N and S poles of a magnetic element are horizontal, the magnetic element moves up and down on the horizontal plane of the magnetic induction of the bipolar magnetic induction integrated circuit.

[0063] Similarly, Figure 3 , 4 In the process, the magnetic element moves up and down on the magnetic induction plane of the bipolar magnetic induction integrated circuit. The transition from the induction polarity of the bipolar magnetic induction integrated circuit and the polarity of the magnetic element being inconsistent to the induction polarity of the bipolar magnetic induction integrated circuit and the polarity of the magnetic element being consistent all satisfy the characteristics of the bipolar magnetic induction integrated circuit being turned on and off.

[0064] The specific working process is as follows:

[0065] First, the output is set to low level when the induction polarity of the bipolar magnetic induction integrated circuit is the same as that of the magnetic element, and to high level when the induction polarity of the bipolar magnetic induction integrated circuit is different from that of the magnetic element; the left N pole and the right S pole of the magnetic element each occupy half of the volume.

[0066] Then, as Figure 3 The magnetic element is above the magnetic induction plane of the bipolar magnetic induction integrated circuit. At this time, the N pole of the magnetic element is close to the S pole of the bipolar magnetic induction integrated circuit, and the bipolar magnetic induction integrated circuit is turned off and outputs a high level.

[0067] Next, the magnetic element continues to move downwards, passing through the magnetic induction horizontal plane of the bipolar magnetic induction integrated circuit (such as...). Figure 2When the magnetic element, at half its overall height, passes through the magnetic induction plane of the bipolar magnetic induction integrated circuit, the bipolar magnetic induction integrated circuit turns on and outputs a low level. The reason is that although the N pole of the magnetic element is always closer to the bipolar magnetic induction integrated circuit, the magnetic element cannot provide the S pole closer to the bipolar magnetic induction integrated circuit during this movement. However, when half of the magnetic element's height passes through the magnetic induction plane of the bipolar magnetic induction integrated circuit, the N pole magnetic flux above the magnetic induction plane of the bipolar magnetic induction integrated circuit is less than the N pole magnetic flux below the magnetic induction plane of the bipolar magnetic induction integrated circuit. After they cancel each other out, the magnetic element can be regarded as having an upper S pole and a lower N pole (with the magnetic induction plane of the bipolar magnetic induction integrated circuit as the boundary). At this time, it is equivalent to the N pole of the magnetic element being close to the N pole of the magnetic induction integrated circuit, and the S pole of the magnetic element being close to the S pole of the magnetic induction integrated circuit. Therefore, the bipolar magnetic induction integrated circuit turns on and outputs a low level.

[0068] Then, Figures 4 to 3 During the reset process, half the height of the magnetic element is higher than the magnetic induction plane of the bipolar magnetic induction integrated circuit, and the polarity is relatively reversed. The bipolar magnetic induction integrated circuit turns off and outputs a high level.

[0069] We can also configure the output to be high when the polarity of the bipolar magnetic induction integrated circuit is the same as that of the magnetic element, and to be low when the polarity of the bipolar magnetic induction integrated circuit is different from that of the magnetic element.
