Anti-interference equipment

Abstract

The invention provides anti-interference equipment comprising a processor, a signal transceiver and a first anti-interference unit. The first signal transmitting end of the signal transceiver is connected with the first signal input end of the first anti-interference unit. The first signal output end of the first anti-interference unit is connected with the first data receiving end of the processor. The second signal transmitting end of the signal transceiver is connected with the second signal input end of the first anti-interference unit. The second signal output end of the first anti-interference unit is connected with the second data receiving end of the processor. The first data transmitting end of the processor is connected with the third signal input end of a second anti-interference unit. The third signal output end of the second anti-interference unit is connected with the first signal receiving end of the signal transceiver. The second data transmitting end of the processor is connected with the signal input end of the second anti-interference unit. The signal output end of the second anti-interference unit is connected with the second signal receiving end of the signal transceiver. The board level noise can be reduced and the interference resistance capacity can be enhanced.

Description

technical field [0001] The invention relates to the field of data communication, in particular to an anti-jamming device. Background technique [0002] With the popularization of smart home and smart home products, in many home environments, there are usually multiple WIFI devices, zigbee devices, Bluetooth devices and high-speed data communication products, and the signal frequency of the internal interface of the product is mostly at 2GHz- 2.5GHz, prone to co-channel interference. [0003] When transmitting data between the internal interface signal line and the CPU, because the signal frequency is mostly in the range of 2GHz-2.5GHz, a large amount of electromagnetic radiation or electromagnetic conduction is generated during transmission, resulting in board-level errors detected by the transceiver physical layer chip of the wireless router. The noise is large. Once the board-level noise is too large, the wireless signal of the router will be interfered with at the same f...

[0002] With the popularization of smart home and smart home products, in many home environments, there are usually multiple WIFI devices, zigbee devices, Bluetooth devices and high-speed data communication products, and the signal frequency of the internal interface of the product is mostly at 2GHz- 2.5GHz, prone to co-channel interference

[0003] When transmitting data between the internal interface signal line and the CPU, because the signal frequency is mostly in the range of 2GHz-2.5GHz, a large amount of electromagnetic radiation or electromagnetic conduction is generated during transmission, resulting in board-level errors detected by the transceiver physical layer chip of the wireless router. The noise is large. Once the board-level noise is too large, the wireless signal of the router will be interfered with at the same frequency when the internal interface signal line and the CPU perform data transmission. When the board-level noise is too large, the wireless signal will be covered or even malfunction. For communication, if the signal strength of the board-level noise is close to that of the router, although the wireless signal can be separated from the board-level noise, the communication is unstable due to excessive interference. Interference will increase the signal strength of the router's wireless signal. Although it can communicate stably, it has high requirements for the processor of the router, and it cannot reduce the interference from the root cause, resulting in a decrease in the signal transmission quality of the router.
