Referring to fig. 1, fig. 1 is a block diagram of a detection circuit 100 according to an embodiment of the invention. The detection circuit 100 is applied to an electronic device, which may be, but is not limited to, a smart phone, a tablet computer, and the like. The electronic equipment comprises a main board and a secondary board. The detection circuit 100 may include a first air interface detection unit 110 and a voltage detection unit 140.
In this embodiment, the first air interface detecting unit 110 may include a first detecting subunit 111, a second detecting subunit 112, and a first connecting subunit 113. The first detecting subunit 111 is disposed on the main board, the second detecting subunit 112 is disposed on the sub-board, and the first detecting subunit 111 is electrically connected to the second detecting subunit 112 through the first connecting subunit 113. The voltage detection unit 140 is electrically connected between the first connection subunit 113 and the second detection subunit 112, and configured to detect a voltage signal between the first connection subunit 113 and the second detection subunit 112, so that air interface detection designed for two boards can be implemented through the above setting.
In this embodiment, when the voltage detected by the voltage detecting unit 140 is within a first preset range, the first air interface detecting unit 110 is in an air interface detection state. When the voltage detected by the voltage detection unit 140 is within a second preset range, the first air interface detection unit 110 is in a conduction detection state. Wherein the minimum value of the second preset range is greater than the maximum value of the first preset range. The first preset range and the second preset range can be set according to actual conditions.
For example, when the voltage detected by the voltage detecting unit 140 is at a low level within a first preset range, it indicates that the first air interface detecting unit 110 is in an air interface detection state. When the voltage detected by the voltage detection unit 140 is at a high level within a second preset range, it indicates that the first air interface detection unit 110 is in a conduction detection state.
Referring to fig. 2, fig. 2 is a schematic diagram of a detection circuit 100 according to an embodiment of the invention. The first connection subunit 113 may include a first antenna connector, a second antenna connector, and a radio frequency (RF Cable). The first antenna connector is disposed on the main board, and the second antenna connector is disposed on the sub-board. The first antenna connector is electrically connected to the first detecting subunit 111, the second antenna connector is electrically connected to the second detecting subunit 112, and the first antenna connector is electrically connected to the second antenna connector through the radio frequency line. With the above arrangement, the first detection subunit 111 is electrically connected to the second detection subunit 112 sequentially via the first antenna connection, the radio frequency line, and the second antenna connector, so as to electrically connect components of the first air interface detection unit 110.
In this embodiment, the first detecting sub-unit 111 may include a first rf signal input terminal, a first capacitor C1 and a first inductor L1, and the second detecting sub-unit 112 may include a second capacitor C2 and a first antenna ANT 1. One end of the first capacitor C1 is electrically connected to the first rf signal input terminal, and the other end is electrically connected to the first antenna connector. One end of the second capacitor C2 is electrically connected to the second antenna connector, and the other end is electrically connected to the first antenna ANT 1. Through the above arrangement, the first rf signal input terminal is electrically connected to the first antenna ANT1 through the first capacitor C1, the first antenna connector, the rf line, the second antenna connector, and the second capacitor C2 in sequence. One end of the first inductor L1 is electrically connected between the first capacitor C1 and the first antenna connector, and the other end is grounded.
In this embodiment, the voltage detection unit 140 includes a GPIO pin, a third capacitor C3, a second inductor L2, and a third connection subunit. The GPIO pin and the third capacitor C3 are arranged on the main board, and the second inductor L2 is arranged on the auxiliary board. One end of the third connection subunit is electrically connected to the GPIO pin, and the other end of the third connection subunit is electrically connected to the first air interface detection unit 110 via the second inductor L2. Therefore, the GPIO pin is electrically connected between the second capacitor C2 and the second antenna connector through the third connection subunit and the second inductor L2 in sequence. One end of the third capacitor C3 is electrically connected between the GPIO pin and the third connection subunit, and the other end is grounded.
In this embodiment, the third connection subunit includes a first board-to-board connector (B to B1), a second board-to-board connector (B to B2), and a Flexible Printed Circuit (FPC). The first board-to-board connector (B to B1) is disposed on the main board, and the second board-to-board connector (B to B2) is disposed on the sub board. The GPIO pin is electrically connected between the second capacitor C2 and the second antenna connector through the first board-to-board connector (B to B1), the flexible circuit board, the second board-to-board connector (B to B2), and the second inductor L2 in sequence.
Under a normal state of the whole device, the first rf signal is radiated from the first capacitor C1, the first antenna connector, the rf line, the second antenna connector, the second capacitor C2 to the first antenna ANT1 in sequence. The GPIO pin is low-level through the first board-to-board connector (B to B1), the flexible circuit board, the second board-to-board connector (B to B2), the second inductor L2, the second antenna connector, the radio frequency line, the first antenna connector, and the first inductor L1 in sequence, and a CPU (Central Processing Unit) electrically connected to the GPIO pin can obtain that the first air interface detection Unit 110 is in an air interface detection state. And calling the air interface software parameters by the CPU to meet corresponding requirements.
The first antenna connector is also used for being electrically connected with a radio frequency test wire so as to conduct detection. When the radio frequency test wire is electrically connected with the first antenna connector, the first radio frequency signal is connected to an instrument through the first antenna connector and the radio frequency test wire. Under the condition, the path from the GPIO pin to the ground is disconnected by the first antenna connector and is in a high level state, the CPU detects the GPIO pin to be in a conduction detection state, and then the conducted software parameters are called to meet corresponding requirements.
The connection reliability of the main board and the auxiliary board can be detected through the level of the GPIO pin. At present, when a reliability experiment is carried out, for example, slight dropping, rolling, dropping and the like can cause instant dropping or permanent dropping of a board-to-board connector and an antenna connector, and further the performance of the whole machine is influenced. The problem is usually quite dull, the reason is difficult to directly check and reproduce, and particularly, the instantaneous falling off causes instantaneous power failure and abnormity of other circuits on the auxiliary board. In this embodiment, when the problem occurs, the GPIO pin level is pulled up instantaneously, the CPU records the state, and the cause is easily determined when the problem is to be checked.
Production lines BtoB and RF Cable are both manual buckling, and a probabilistic buckling failure problem exists. And in a detection station before the rear shell of the whole machine is buckled, a detection procedure for the GPIO pin is added. If the GPIO pin is at low level, BtoB and RFCable are successfully buckled; if the GPIO pin is high level, BtoB and the test line are buckled and failed. Therefore, repeated machine dismantling can be avoided, and the first production line yield and efficiency are improved.

Wherein the test socket may be, but is not limited to, a radio frequency test socket.
One end of the sixth capacitor C6 is electrically connected between the third inductor C3 and the first board-to-board connector (B to B1), and the other end is grounded to increase the isolation between the rf signals inputted through the rf input terminal.
In this embodiment, the voltage detection unit 140 may further include a fourth inductor L4. The GPIO pin is electrically connected between the test socket and the fifth capacitor C5 through the fourth inductor L4. The GPIO pin is electrically connected to the first board-to-board connector (B to B1) through the fourth inductor L4, the test socket, and the third inductor L3 in sequence.

Thus, air interface detection may be performed via the antenna connector and/or the test socket.

A capacitor for increasing the isolation of the radio frequency signal is still disposed between the first air interface detection unit 110 and the second first air interface detection unit 110.
