Description

Technical Field

[0001] The utility model relates to a wired communication connection and power supply circuit for a wireless communication module. Background Art

[0002] Existing wireless communication modules such as WIFI usually have an automatic shutdown strategy for automatically shutting down the power supply connection of the communication module to reduce battery consumption. The principle is to automatically shut down the communication module after it has not been used for a certain period of time through timing. The disadvantage is that the communication module needs to be manually restarted when it is used subsequently, which is not convenient for improving the user experience. It is necessary to solve this problem. Utility Model Content

[0003] The utility model overcomes the deficiencies of the above-mentioned technologies and provides a wired communication connection and power supply circuit for a wireless communication module.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A wired communication connection and power supply circuit for a wireless communication module, comprising a first unidirectional conduction module 1, a second unidirectional conduction module 2, a wireless communication module 3, a controlled power supply module 4, and an enabling module 5 with an output delay function and used to control the controlled power supply module 4 to supply power to the wireless communication module 3 when the first unidirectional conduction module 1 is turned on and / or when the second unidirectional conduction module 2 is turned on. The wireless communication module 3 is provided with a wired communication connection receiving end 31 and a wired communication connection transmitting end 32. The first unidirectional conduction module 1 is forwardly connected between the wired communication connection receiving end 31 and the signal input end of the enabling module 5, the second unidirectional conduction module 2 is forwardly connected between the wired communication connection transmitting end 32 and the signal input end of the enabling module 5, and the enabling signal output end of the enabling module 5 is connected to the control signal input end of the controlled power supply module 4.

[0006] Preferably, the first unidirectional conducting module 1 is a diode D1 connected in a forward direction between the wired communication connection receiving end 31 and the signal input end of the enabling module 5 .

[0007] Preferably, the second unidirectional conducting module 2 is a diode D2 connected in a forward direction between the wired communication connection transmitting terminal 32 and the signal input terminal of the enabling module 5 .

[0008] Preferably, the wireless communication module 3 is a WIFI communication module or an infrared communication module.

[0009] Preferably, the controlled power supply module 4 adopts a controlled DC-DC circuit.

[0010] Preferably, the enabling module 5 includes a resistor R1 and a capacitor C1. One end of the resistor R1 is connected to one end of the capacitor C1 and serves as a signal input end and an enabling signal output end of the enabling module 5, and is connected to the reverse end of the first unidirectional conduction module 1, the reverse end of the second unidirectional conduction module 2, and the control signal input end of the controlled power supply module 4. The other end of the resistor R1 is connected to the other end of the capacitor C1 and then grounded.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The structure of this case is simple and easy to implement. The setting of the first unidirectional conduction module and the second unidirectional conduction module has the functions of forward conduction and reverse isolation. When the wired communication connection receiving end and / or the wired communication connection transmitting end are at a high level, the enabling module is triggered to control the controlled power supply module to supply power to the wireless communication module, so that the wireless communication module can be powered on and work. In addition, since the enabling module has an output delay function, the enabling module stops controlling the controlled power supply module to supply power to the wireless communication module only after a period of time when both the wired communication connection receiving end and the wired communication connection transmitting end are at a low level, which is beneficial to the delayed work and subsequent shutdown of the wireless communication module and has good practicality. In addition, the above setting makes it convenient for the external circuit to wake up the wireless communication module of this case at any time through the wired communication connection, which has good practicality.

[0013] 2. The enabling module described in this case adopts an RC parallel circuit, which realizes the output delay function by discharging energy storage, and is easy to implement. When the wired communication connection receiving end and the wired communication connection transmitting end are both at a low level and the RC parallel circuit discharges for a period of time, the enabling module stops controlling the controlled power supply module to supply power to the wireless communication module, which is beneficial to the delayed operation of the wireless communication module and the subsequent shutdown to save power, and has good practicality.

[0017] As described above, in a specific implementation, the wireless communication module 3 of this case is connected to the external circuit by wired communication through the wired communication connection receiving end 31 and the wired communication connection transmitting end 32 .

[0018] As described above, the structure of this case is simple and easy to implement. The setting of the first unidirectional conduction module 1 and the second unidirectional conduction module 2 has the functions of forward conduction and reverse isolation. When the wired communication connection receiving end 31 and / or the wired communication connection transmitting end 32 are at a high level, the enabling module 5 is triggered to control the controlled power supply module 4 to supply power to the wireless communication module 3, so that the wireless communication module 3 can be powered on and work. In addition, since the enabling module 5 has an output delay function, only when the wired communication connection receiving end 31 and the wired communication connection transmitting end 32 are both at a low level for a period of time, the enabling module 5 stops controlling the controlled power supply module 4 to supply power to the wireless communication module 3, which is beneficial to the delayed work and subsequent shutdown of the wireless communication module 3, and has good practicality. In addition, the above setting makes it convenient for the external circuit to wake up the wireless communication module 3 of this case at any time through the wired communication connection, which has good practicality.

[0019] As described above, in a specific implementation, the first unidirectional conducting module 1 is a diode D1 connected in a forward direction between the wired communication connection receiving terminal 31 and the signal input terminal of the enabling module 5 , which is convenient to implement.

[0020] As described above, in a specific implementation, the second unidirectional conducting module 2 is a diode D2 connected in a forward direction between the wired communication connection transmitting terminal 32 and the signal input terminal of the enabling module 5 , which is convenient to implement.

[0021] As described above, in a specific implementation, the wireless communication module 3 is a WIFI communication module or an infrared communication module.

[0022] As described above, in specific implementation, the controlled power supply module 4 adopts a controlled DC-DC circuit.

[0023] As described above, in a specific implementation, the enabling module 5 includes a resistor R1 and a capacitor C1. One end of the resistor R1 is connected to one end of the capacitor C1 and serves as a signal input end and an enabling signal output end of the enabling module 5 and is connected to the reverse end of the first unidirectional conduction module 1, the reverse end of the second unidirectional conduction module 2, and the control signal input end of the controlled power supply module 4. The other end of the resistor R1 is connected to the other end of the capacitor C1 and is grounded.

[0024] As described above, the enabling module 5 described in this case adopts an RC parallel circuit, which realizes the output delay function by energy storage and discharge, and is easy to implement. When the wired communication connection receiving end 31 and the wired communication connection transmitting end 32 are both at a low level and the RC parallel circuit discharges for a period of time, the enabling module 5 stops controlling the controlled power supply module 4 to supply power to the wireless communication module 3, which is beneficial to the delay work of the wireless communication module 3 and the subsequent shutdown to save power, and has good practicality.

[0025] As mentioned above, this case protects a wired communication connection and power supply circuit for a wireless communication module. All technical solutions that are the same or similar to this case should be deemed to fall within the protection scope of this case.
