[0027] figure 1 Shown is a block diagram of the circuit structure of the antenna connection state detection device, which includes an antenna unit 1 , a voltage detection module 2 , a connection state judging module 3 and a wireless communication unit 4 .

[0028] The antenna unit includes an antenna 11 and a matching module 12 .

[0029] In this embodiment, the antenna 11 is used to receive a wireless signal and transmit it to the wireless communication unit 4 after being stabilized by the matching module 12 . The antenna 11 is an antenna in an existing wireless communication device, and other forms of antennas may also be used according to the actual needs of the wireless communication device. The matching module 12 is set according to parameters such as impedance and gain of the antenna 11 used, so as to stabilize the wireless signal received by the antenna as much as possible. Since both the antenna unit 1 and the wireless communication unit 4 in this embodiment can adop...

[0038] figure 2 Shown is a block diagram of the circuit structure of the antenna connection state detection device, which includes an antenna 11 , a wireless communication chip 3 , resistors 21 , 22 and 23 , an inductor 121 , and a capacitor 122 . The wireless communication chip 3 includes a power terminal 31 , an analog-to-digital converter 32 and a communication module 33 .

[0039] The inductor 121 and the capacitor 122 in this embodiment constitute a matching module, and together with the antenna 11 constitute an antenna unit. Wherein the equivalent impedance of the antenna 11 is R 11 =10KΩ, so in order to achieve the purpose of stabilizing the wireless signal received by the antenna, the inductor 121 is used as L 121 =47nH, capacitor 122 is C 122 =33pF matching module to stabilize the received wireless signal.

[0040] The resistors 21 , 22 and 23 in this embodiment together with the power terminal 31 and the analog-to-digital converter 32 in the wireless communicati...

Abstract

The invention discloses an antenna connection status detection device and a method thereof. The antenna connection status detection device comprises a voltage detection module and a connection state judgment module, wherein the voltage detection module is used for presetting a voltage detection time interval and detecting the voltage on the antenna unit according to the voltage detection time interval; and the connection state judgment module is used for presetting the corresponding relation between voltage and connection state and judging the connection state of the antenna unit according to the detected voltage and the corresponding relation. With the antenna connection status detection device and the detection method thereof, the state of an antenna is judged by detecting the voltage of the antenna, the compatibility with various antennas is realized by customizing the antenna state by a user, more specific antenna state information can be provided, so that convenience is provided for antenna detection for the user, and the antenna detection efficiency is increased.

Description

technical field [0001] The invention relates to an antenna connection state detection device and a detection method thereof, in particular to an antenna connection state detection device of a wireless communication device and a detection method thereof. Background technique [0002] Current wireless devices generally use an external antenna to realize the communication function of the wireless device. Therefore, if the communication is affected during normal communication, and the user cannot make phone calls, send text messages or other normal communication activities related to network communication, it may not be the cause of the network side, but may be the antenna in the wireless device. It is caused by wrong connection status, for example, the grounding caused by moisture in some environments, or the communication failure caused by loose antenna head, overvoltage and other reasons. [0003] In order to detect whether an external antenna is connected, a dedicated anten...
