Description

Technical Field

[0001] The present invention relates to the technical field of communication equipment, and in particular to a network cable insertion detection method. Background Art

[0002] With the development of Internet communication technology, network communication technology has been widely used in products such as handheld mobile terminals (PDAs) and embedded industrial control boards. These devices are usually small in size and battery-powered, and have strict requirements on standby current and power consumption. Since the power consumption of the Ethernet network card is greatly different when it is turned on or not, it is necessary to control the opening and closing of the Ethernet network card according to whether a network cable is inserted into the network port to reduce power consumption. The commonly used method is to add additional pins or other switch devices to the network port through a customized RJ45 network port socket. When the network cable is inserted, the contact state of the switch device is changed to determine whether the network cable is inserted into the network port.

[0003] The invention patent "A method, device and terminal for detecting network port insertion" with publication number CN106294057A discloses a method for detecting network port insertion: two pins PinA and PinB are added to the general network port, and two springs are added to the inner side wall of the network port. The springs are defined as spring A and spring B, and spring A and spring B are connected to PinA and PinB respectively. When the network cable is inserted into the network port, spring A and spring B will be squeezed to contact. When the network cable is pulled out, spring A will recover, and spring A and spring B will be disconnected. In this way, the on-off state of PinA and PinB will change before and after the network cable is inserted, so as to determine whether the network cable is inserted into the network port. This method of automatically detecting the connection status of the Ethernet network interface requires a new mold because the designed network port is different from the common network ports on the market, which incurs mold opening fees and increases product costs. In addition, the network port can only determine whether the network cable is physically inserted but cannot confirm whether the network cable is connected to the router. If the network cable is only inserted into the device but not connected to the router, the device will think that the network cable is connected and turn on chips such as the network card, resulting in increased power consumption. Summary of the invention

[0004] In order to solve the defects in the prior art, the present invention provides a network cable insertion detection method.

[0007] When the network cable connected to the router is inserted, the level on the path between the Ethernet switch and the processor will be pulled low, thereby generating an interrupt signal. The processor confirms the insertion of the network cable through the interrupt signal, switches the Ethernet switch path to the network transformer, turns on the network card at the same time, and the device is connected to the router through the network cable; when the network cable not connected to the router is inserted, the level on the path between the Ethernet switch and the processor is always in a high state, the above-mentioned interrupt signal will not be generated on the path, and the processor confirms that the network cable not connected to the router is inserted.
