[0002] IR transmitting devices and IRM receiving devices are two key components in an infrared communication system, which are widely used in technical fields such as household appliance control, industrial automation, security monitoring, etc. They jointly realize the transmission and reception of wireless signals. The data to be sent is first modulated onto the infrared carrier wave emitted by the IR LED, and then transmitted through the infrared light wave. After the IRM receiving device receives the infrared signal, it converts the optical signal into an electrical signal, amplifies and demodulates it, and finally outputs the original data.

[0003] At present, the IR transmitting devices and IRM receiving devices on the market are mainly separate types. One end of the IR transmitting device is used for signal transmission, and the other end of the IRM receiving device is used for signal reception. The separated state of the existing receiving system is not convenient for application in the sensing feedback circuit, and the control circuit of a specific protocol cannot disable the IR transmitting device. The IR transmitting device will perform misoperations on the device, turn on the device, and cause the device to consume power. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an IRM signal transmitting and receiving module. By using a contact sensor to control the switch of the IR transmitting device and combining it with the IRM receiving device, a remote control and sensing receiving function module is formed, which can assist in providing multiple device opening modes, realizing the disabling of the IR transmitting device in the module under normal circumstances. The IRM receiving device receives the remote control signal to turn on the device, and when the contact sensor senses a human body, the IR transmitting device operates, and the IRM receiving device receives the IR transmitting device signal feedback by the human body to control the device to turn on, making the opening mode of the electrical device more user-friendly and intelligent.

[0005] The utility model is realized through the following technical solutions:

[0006] An IRM signal transmitting and receiving module includes a bottom plate and a housing. The housing is fixedly connected to the bottom plate, forming two spaces. An IRM receiving device and an IR transmitting device are respectively fixedly connected to the bottom plate in the two spaces.

[0007] Further, an opening communicating with the outside is provided on the side shell of the housing opposite to the signal receiving end of the IRM receiving device and the signal output end of the IR transmitting device.

[0008] Further, four pins are connected to the bottom of the IRM receiving device, namely pin one, pin two, pin three, and pin four, and a positive pin and a negative pin are connected to the bottom of the IR transmitting device.

[0009] Further, pin 1 and pin 4 are the ground terminals of the IRM receiving device, connected to the negative pole of the power supply and the ground wire of the circuit.

[0010] Further, pin 2 is the input terminal of the IRM receiving device, connected to the positive pole of the power supply.

[0011] Further, pin 3 is the output terminal of the IRM receiving device, connected to the control unit of the electrical equipment.

[0012] Further, the positive pole pin of the IR transmitting device is connected to the output pin of the control unit of the electrical equipment, and the negative pole pin is connected to the ground wire of the circuit.

[0013] Compared with the prior art, the present utility model has the following obvious advantages:

[0014] 1. In the case where the operator uses a remote control or other device to transmit a signal to remotely control the electrical equipment, the IR transmitting device in the disabling module is disabled, and the IRM receiving device receives the remote control signal to turn on the equipment. The IR transmitting device will not emit a signal to the IRM receiving device, resulting in misoperation of the equipment.

[0015] 2. Since the present utility model uses a contact sensor connected to the IR transmitting device to form a sensing function module, when the operator approaches, the contact sensor senses the object and sends information to the control unit. The control unit commands the IR transmitting device to operate, and the IRM receiving device receives the signal of the IR transmitting device fed back by the object to control the equipment switch to turn on, making the equipment start more conveniently and intelligently.

[0016] 3. Since the IR transmitting device and the IRM receiving device are encapsulated in the same module in the present utility model, it is more convenient to install, connect and use for realizing the transmission and reception of IRM signals, improving the production and assembly efficiency of related equipment.

[0023] As Figure 1 、 Figure 2 and Figure 3 shown, the present utility model provides an IRM signal transmitting and receiving module, including a bottom plate 1, a housing 2, an IRM receiving device 3 and an IR transmitting device 4; in this embodiment, the housing 2 is fixedly connected to the bottom plate 1, forming two spaces with the bottom plate 1. The bottom plate 1 in the two spaces is respectively fixedly connected with an IRM receiving device 3 and an IR transmitting device 4. On the side of the housing 2 opposite to the signal receiving end of the IRM receiving device 3 and the signal output end of the IR transmitting device 4, there is an opening communicating with the outside; the bottom of the IRM receiving device 3 is connected with four pins, namely pin one, pin two, pin three and pin four. Pin one and pin four are the grounding ends 301 of the IRM receiving device 3, connected to the negative pole of the power supply and the ground wire of the circuit.

The contact sensor connected to the IR transmitting device 4 cannot sense the human body, and the IR transmitting device 4 is in a disabled state and will not emit a control signal to cause misoperation of the electrical equipment. The control signal transmitted by the external remote control is received by the signal receiving end of the IRM receiving device 3. The IRM receiving device 3 converts the received optical signal into an electrical signal, amplifies and demodulates it to obtain the original data, and transmits the data from the output end 303 to the control unit of the electrical equipment to control the electrical equipment to turn on.

[0025] When the operator does not use the external remote control, the operator approaches the electrical equipment and the IRM signal transmitting and receiving module connected to the electrical equipment, and the contact sensor connected to the IR transmitting device 4 senses the human body. The contact sensor sends a signal to the input pin of the control unit through the output pin, and the control unit controls the IR transmitting device 4 to turn on, and the IR transmitting device 4 is released from the disabled state. The IR transmitting device 4 sends a control signal to the human body, and the human body feeds the control signal back to the IRM signal transmitting and receiving module. The control signal is received by the signal receiving end of the IRM receiving device 3, and the IRM receiving device 3 converts the received optical signal into an electrical signal and amplifies and demodulates it to obtain the original data, and transmits the data to the control unit of the electrical equipment from the output end 303 to control the electrical equipment to turn on.
