[0002] With the continuous development of technology, communication is ubiquitous in daily life. Some communication devices are near-infrared communication devices. Due to the relatively low power consumption of near-infrared devices and for safety reasons, the transmitting and receiving devices of infrared communication devices need to be closely connected.

[0061] As described in the background section, in related technologies, near-infrared communication devices typically employ a one-to-one transmit / receive method. During use, the transmitter of the tool device and the receiver of the target device are aligned, and the receiver of the tool device and the transmitter of the target device are also aligned. However, this one-to-one transmit / receive method places strict requirements on the relative positions of the tool device and the target device. Once the tool device and the target device rotate relative to each other, the alignment between the two sets of transmitters and receivers is disrupted, the distance between the receiver and the transmitter becomes larger, signal transmission between the tool device and the target device is hindered, signal transmission stability is poor, and communication is easily interrupted.

[0062] To address the aforementioned technical problems, this application proposes a near-infrared communication device, comprising a target device and a tool device. The target device includes a first circuit board, a first infrared transmitter, and a first infrared receiver, the first infrared transmitter and the first infrared receiver being disposed on the first circuit board. The tool device is detachably connected to the target device, and the tool device includes a second circuit board, a second infrared transmitter for signal connection with the first infrared receiver, and a second infrared receiver for signal connection with the first infrared transmitter. The second infrared transmitter and the second infrared receiver are disposed on the second circuit board. Of the two, the second infrared transmitter and the second infrared receiver are either the first component or the second component. When the second infrared transmitter is the first component and the target device and the tool device are connected, the second infrared transmitter... The second infrared transmitter is positioned opposite to the first infrared receiver, ensuring signal transmission between them. When the second infrared receiver is the first component and the target device and tool device are connected, the second infrared receiver is positioned opposite to the first infrared transmitter, ensuring signal transmission between them. At least two second components are arranged circumferentially around the first component. When the second infrared transmitter is the first component, the probability of signal connection between the first infrared transmitter and the second infrared receiver is increased. This avoids communication failure after the target device and tool device rotate relative to each other, and improves the success rate of bidirectional communication between the target device and the tool device.

[0063] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0064] refer to Figure 1 This application provides a near-infrared communication device 100. The near-infrared communication device 100 includes a target device 1 and a tool device 2. The tool device 2 can be detachably connected to the target device.

[0065] The target device 1 can be an instrument such as a flow meter. The flow meter can be a gas flow meter, a water meter, etc.

[0066] Tool device 2 can be used to inspect target device 1. To ensure the measurement accuracy of the flow meter, an accuracy test is required after assembly. If the flow meter's measurement accuracy is abnormal, it needs to be calibrated. Tool device can connect to the target device to test its accuracy.

[0067] Tool device 2 can be used to acquire data from the target device. In order to read data from the flow meter, the tool device is connected to the target device to acquire the data from the target device.

[0068] In some embodiments, reference Figure 2 The target device 1 may include a first circuit board 11. The target device 1 may include a first infrared emitter 12. The first infrared emitter 12 may be disposed on the first circuit board 11.

[0069] refer to Figure 2 The target device 1 may include a first infrared receiver 13. The first infrared receiver 13 may be connected to the first circuit board 11.

[0070] In some embodiments, reference Figure 4 The target device 1 may include a first housing 14. A first circuit board 14 is disposed within the first housing 14. A first infrared transmitter is disposed within the first housing 14. A first infrared receiver is disposed within the first housing 14.

[0071] In some embodiments, a first receiving cavity is formed within the first housing 14. A first circuit board 14 is disposed within the first receiving cavity. A first infrared transmitter is disposed within the first receiving cavity. A first infrared receiver is disposed within the first receiving cavity.

[0072] In some embodiments, reference Figure 2 , Figure 4 and Figure 5 The tool device 2 may include a second circuit board 21. The tool device 2 may include a second infrared transmitter 22 for signal connection with the first infrared receiver. The second infrared transmitter 22 is disposed on the second circuit board 21.

[0073] The tool device 2 may include a second infrared receiver 23 for signal connection with the first infrared transmitter. The second infrared receiver 23 may be disposed on the second circuit board 21.

[0074] The first infrared transmitter 12 is used to transmit signals. The second infrared receiver is used to receive signals transmitted by the first infrared transmitter.

[0075] The second infrared transmitter 22 is used to transmit signals. The first infrared receiver is used to receive the signals transmitted by the second infrared transmitter.

[0076] In some embodiments, reference Figure 5 and Figure 6 Of the second infrared transmitter and the second infrared receiver, one is the first component a, and the other is the second component b.

[0077] The second element has at least two parts. At least two second elements are arranged circumferentially around the first element.

[0078] When the second infrared transmitter is the first component and the target device and the tool device are connected, the second infrared transmitter is positioned opposite to the first infrared receiver; when the second infrared receiver is the first component and the target device and the tool device are connected, the second infrared receiver is positioned opposite to the first infrared transmitter.

[0079] When the second infrared transmitter is the first component, and the target device and tool device are connected, the second infrared transmitter is positioned opposite the first infrared receiver, ensuring signal transmission between them. When the second infrared receiver is the first component, and the target device and tool device are connected, the second infrared receiver is positioned opposite the first infrared transmitter, ensuring signal transmission between them. Having multiple second components increases the probability of signal connection between the first and second infrared transmitters when the second infrared transmitter is the first component, preventing communication failure after relative rotation of the target device and tool device, and improving the success rate of bidirectional communication between the target device and tool device.

[0080] In some embodiments, when the target device and the tool device are connected, the first infrared transmitter and the first infrared receiver are located on the side of the first circuit board closer to the second circuit board, and the second infrared transmitter and the second infrared receiver are located on the side of the second circuit board closer to the first circuit board, which facilitates the signal connection between the target device and the tool device.

[0081] In some embodiments, the target device and the tool device are rotatably connected so that the second component is signal-connected to the first infrared transmitter or the first infrared receiver.

[0082] The target device and tool device are rotatably connected, allowing them to rotate relative to each other after connection. This eliminates the need for strict positioning of the target device and tool device, making them suitable for diverse installation environments. When the connection between the target device and tool device is restricted, relative rotation can ensure a normal connection. Furthermore, when the signal connection between the second component and the first infrared transmitter or receiver is restricted, relative rotation can improve the success rate of bidirectional communication between the target device and tool device.

[0083] In some embodiments, reference Figure 6 The plane perpendicular to the extension direction of the first and second pieces is defined as the first plane.

[0084] The projection of the first object onto the first plane is the first projection. The projection of the second object onto the first plane is the second projection.

[0085] The center of the first projection is the first center, the minimum distance between the second projection and the first center is the first minimum distance h2, and the maximum distance between the second projection and the first center is the first maximum distance h3.

[0086] The first minimum distance of each second projection is less than the first distance h1, and the first maximum distance of each second projection is greater than the first distance h1, so that the distances between all second pieces and the first pieces will not differ significantly.

[0087] In some embodiments, when the target device and the tool device are connected, of the first infrared transmitter and the first infrared receiver, the one opposite to the first component is the third component c, and the other is the fourth component d.

[0088] In some embodiments, reference Figure 7 When the target device and the tool device are connected, the projection of the third part on the first plane is the third projection, and the projection of the fourth part on the first plane is the fourth projection.

[0089] The center of the third projection is the third center, the minimum distance between the fourth projection and the third center is the second minimum distance h4, and the maximum distance between the fourth projection and the third center is the second maximum distance h5.

[0090] The second minimum distance of each fourth projection is less than the first distance h1, and the second maximum distance of each fourth projection is greater than the first distance h1, so that the distance between the second and fourth pieces is not too large, which facilitates the signal connection between the fourth and second pieces.

[0091] In some embodiments, when the target device and the tool device are connected, the extension directions of the third and fourth pieces are perpendicular to the first plane.

[0092] In some embodiments, when the target device and the tool device are connected, the center of the third projection is opposite to the center of the first projection, so that the first and third pieces are aligned, facilitating signal connection between the first and third pieces, and the second and fourth pieces can be aligned, facilitating signal connection between the second and fourth pieces.

[0093] In some embodiments, the center of the second projection is a second center, and the distance between two adjacent second centers is equal, which enables the second part to be evenly arranged around the first part. This allows the target device and the tool device to achieve bidirectional communication between them as much as possible when they rotate relative to each other by a certain angle, thereby improving the communication success rate between the target device and the tool device.

[0094] In some embodiments, at least two fourth elements are provided, with the two fourth elements arranged circumferentially around the third element, which can improve the success rate of signal connection between the second and fourth elements.

[0095] In some embodiments, when the target device and the tool device are connected, the center of the fourth projection is the fourth center, and the distance between two adjacent fourth centers is equal, which enables the fourth part to be evenly arranged around the third part. This allows the target device and the tool device to achieve bidirectional communication between them as much as possible when they rotate relative to each other by a certain angle, thereby improving the communication success rate between the target device and the tool device.

[0096] In some embodiments, when the tool device sends information to the target device, all the second infrared transmitters operate and transmit the same data. If a first infrared receiver receives information sent by one of the second infrared transmitters, it is considered that the information transmission from the tool device to the target device has been completed.

[0097] When the target device sends information to the tool device, all the first infrared transmitters are working and all the first infrared transmitters transmit the same data. As long as one of the second infrared receivers receives the information sent by one of the first infrared transmitters, it is considered that the information transmission from the target device to the tool device has been completed.
