According to the current communication technology theory, when a wireless device and a wireless terminal transmit data, the data is divided into TX and RX directions. The TX (transmit) direction refers to the antenna of the wireless device to the antenna of the wireless terminal, and the RX (Receive) direction refers to the antenna of the wireless terminal to the antenna of the wireless device. The wireless device in the invention refers to devices such as a wireless Access Point (AP) (Access Point) and a wireless router and the like which construct a wireless network in a narrow sense, and does not include wireless devices in a broad sense such as a wireless terminal.
Research shows that the performance of a wireless communication system is greatly influenced by an antenna of a wireless device, and when the wireless device and a wireless terminal transmit data, the signal strength of the wireless device in the TX/RX direction determines the negotiation rate at which the wireless device and the wireless terminal transmit data; when the signal strength of the antenna TX/RX direction of the wireless device is abnormal, the data transmitted by the two parties cannot be analyzed normally by the other party, and the transmitted data is retransmitted or discarded, which affects the data transmission efficiency. Therefore, it is important how to effectively and accurately detect an antenna failure of a wireless device.
In the conventional wireless equipment antenna fault detection mode in the prior art, when certain wireless equipment is suspected to have antenna faults, the wireless equipment is manually processed in a field environment, and the strength of a wireless signal in the TX/RX direction of the wireless equipment antenna is detected by a special wireless signal measuring instrument to determine whether the antenna has the fault problem, so that a large amount of labor and time cost is consumed.

(A3) comparing Pn corresponding to all wireless terminals with a preset antenna RX direction judgment threshold value α, if all the wireless terminals meet Pn being more than or equal to α, indicating that the RX directions of the two antennas are abnormal and a fault exists, otherwise, indicating that the RX directions of the two antennas are normal;
(A4) re-assigning two antennas to perform steps (A1) - (A3) until the antennas of the wireless device are detected.
Specifically, when two antennas are reassigned, at least one of the antennas is an antenna that has not been detected on the wireless device, and the self-test of all the antennas is generally completed in a pairwise pairing manner.
Further, the antenna fault self-checking method of the wireless device further comprises the following steps:
(B) TX Direction self-test
(B1) Appointing two antennas to be tested, enabling one antenna to be tested to send data to the other antenna to be tested for a period of time, then changing the data sending direction of the two antennas to be tested, and sending the data for the same time again;
(B2) analyzing and acquiring wireless signal strengths ST1 and ST2 of the two antennas to be tested in the TX direction from the data sent twice respectively, and calculating an absolute value Q = | ST1-ST2| of the difference value of the wireless signal strengths of the two antennas to be tested;
(B3) comparing the absolute value Q with a preset antenna TX direction judgment threshold value β, if Q is more than or equal to β, indicating that the TX directions of the two antennas to be tested are abnormal and a fault exists, otherwise indicating that the TX directions of the two antennas to be tested are normal;
(B4) and (B1) reassigning the two antennas to be tested to carry out the steps (B4) until the antennas of the wireless equipment are all detected.
Specifically, in the step (B1), data transmission and reception between the two antennas to be tested are performed by calling a transmission signal loopback function of the wireless device.
And configuring an enabling period T for the loopback function of the transmitting signal, wherein the time for sending data by the antenna to be tested is matched with the enabling period T so as to reduce the influence of the test on the normal working state of the wireless equipment.

(2) The invention skillfully utilizes the wireless terminal resources in the network environment when carrying out RX direction self-checking, can analyze and collect the wireless signal intensity of the wireless terminals when the wireless terminals normally communicate, thereby not influencing the normal wireless network use, having high-efficiency resource utilization rate, further reducing the time cost, only occupying the antenna resources locally when carrying out TX direction self-checking, and reducing the influence on the normal use of the wireless equipment to the minimum under the condition of meeting the detection requirement.
