The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0030] Example 1

[0031] This embodiment 1 provides a single board detection system for an acquisition terminal, which is the hardware design part of the present invention:

[0032] See also Figure 1 ,The single board detection system for the acquisition terminal includes: a host computer and a test box.

[0033] The host computer is used to issue the detection task set. The host computer can be any one or more electronic devices such as a mobile phone, a foldable electronic device (such as a foldable mobile phone), a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, etc., which can store and run programs.

[0034] The test box includes: a box body and a testing tool. The box body can adopt a chassis design. The box body is equipped with a mounting slot for detachably mounting a single board of the acquisition terminal to be tested. The mounting slot and the acquisition terminal to be tested can adopt a snap-on design - the acquisition terminal to be tested needs to be pressed into the mounting slot with force.

[0035] The bottom of the installation slot is provided with a plurality of crimping terminals for electrically connecting to the acquisition terminal board to be tested, so that after the acquisition terminal to be tested is pressed into the installation slot, the function detection connection point of the acquisition terminal to be tested will contact the crimping terminals to achieve electrical connection.

[0036] In addition, a clamping member may be added to the box to clamp the single board of the acquisition terminal to be tested in the installation slot. For example, a telescopic rod connected to a pressure plate may be provided in the box: when the acquisition terminal to be tested is installed, the telescopic rod is controlled to shorten to avoid interference with the installation of the acquisition terminal to be tested; after the acquisition terminal to be tested is installed, the telescopic rod is controlled to extend so that the pressure plate presses the acquisition terminal to be tested.

[0037] The detection tool is arranged in the box. The detection tool can be designed to be detachable, but it is generally not removed after being installed. The detection tool is electrically connected to the crimping terminal and is connected to the host computer based on the RS485 protocol. Among them, the detection tool and the crimping terminal can be directly connected through a data cable; of course, a PCB circuit board can also be installed in the box and the crimping terminal can be arranged on the PCB circuit board, so that the detection tool and the PCB circuit board are connected through a wire.

[0038] For the testing tooling, it has multi-channel communication functions, including RS485, CAN, Bluetooth, infrared, etc., and can communicate with the acquisition terminal to be tested through multiple protocols. In consideration of the adaptability and stability of the connection, the communication connection with the host computer is based on the RS485 protocol.

[0039] In general, after the acquisition terminal board to be tested is installed in the installation slot, the detection tooling receives the detection task set sent by the host computer and performs single-board detection on the acquisition terminal board to be tested.

[0040] This embodiment 1 also provides a single board detection method for the acquisition terminal, which is the software design part of the present invention:

[0041] The single board detection method for the acquisition terminal is applied to the above-mentioned single board detection system for the acquisition terminal, that is, the two constitute a combination of software and hardware.

[0042] See also Figure 2 , the single board detection method for the acquisition terminal includes:

[0043] Step 1: Install the acquisition terminal to be tested into the installation slot, first confirm whether the communication between the host computer and the detection tooling is normal, and then confirm whether the communication between the detection tooling and the acquisition terminal to be tested is normal;

[0044] If all are normal, proceed to step 2;

[0045] Otherwise, troubleshoot the abnormal communication and repeat step 1;

[0046] This step 1 is intended to ensure normal communication between components, which is the prerequisite for single board detection.

[0047] Specific:

[0048] (1) Methods for confirming whether the communication between the host computer and the detection tooling is normal include:

[0049] Step 101, the host computer sends a communication test package to the detection tooling;

[0050] If the detection tool receives the communication test package, it will return a test confirmation package to the upper computer;

[0051] Step 102, determining whether the host computer has received the test confirmation packet;

[0052] If yes, the communication is normal;

[0053] Otherwise, the communication is wrong;

[0054] Step 103, repeat step 101 N times;

[0055] If the number of consecutive errors exceeds the threshold number A, the communication between the host computer and the detection tooling is abnormal;

[0056] Otherwise, the communication between the host computer and the detection tooling is normal.

[0057] (2) The method for confirming whether the communication between the detection tool and the acquisition terminal to be tested is normal includes:

[0058] Step 201, the host computer sends a communication instruction to the detection tool; the detection tool receives the communication instruction, that is, sends a communication test package to the acquisition terminal to be tested;

[0059] If the acquisition terminal to be tested receives the communication test package, it returns a test confirmation package to the detection tooling;

[0060] When the detection tool receives the test confirmation package, it returns a test success signal to the upper computer;

[0061] Step 202, determining whether the host computer receives a test success signal;

[0062] If yes, the communication is normal;

[0063] Otherwise, the communication is wrong;

[0064] Step 203, repeat step 101 N times;

[0065] If the number of consecutive errors exceeds the threshold number A, the communication between the detection tool and the acquisition terminal to be tested is abnormal;

[0066] Otherwise, the detection tooling communicates normally with the acquisition terminal to be tested.

[0067] It should be noted that the values ​​of N and A can be adjusted according to actual conditions. The general recommendation is: N=10; A=3.

[0068] Step 2: The host computer sends the inspection task set to the inspection tooling;

[0069] When the communication is normal, the host computer can send the inspection task set to the inspection tooling.

[0070] The detection task set includes several detection tasks designed for the acquisition terminal board to be tested, such as: whether the output voltage of each module of the acquisition terminal board to be tested is normal, whether the second pulse output is normal, whether the switch output is normal, etc.

[0071] Step 3: The detection tooling receives the detection task set sent by the host computer, and performs single-board detection on the acquisition terminal board to be tested according to the preset rules until the detection task set is completed.

[0072] The preset rules include:

[0073] S31, classifying the detection task set by priority to obtain a detection sequence table;

[0074] Among them, the detection task set includes: M detection tasks Task 1 ~Task M ;

[0075] The detection sequence table includes: arranged in order and related to Task 1 ~Task M The corresponding serial numbers;

[0076] It should be noted that the detection sequence table is intended to optimize the order of issuing the detection task set so as to improve the detection efficiency while ensuring that the single board detection is performed correctly.

[0077] For details, see Figure 3 , the construction method of the detection sequence table includes:

[0078] S311, obtain the task of the detection task set 1 ~Task M ;

[0079] S312, Construction and Task 1 ~Task M There is a one-to-one correspondence between the initial sequences;

[0080] The initial sequence includes: from sequence number 1 to sequence number M;

[0081] S313, Task 1~Task M Perform priority classification to update the initial sequence and obtain an updated sequence;

[0082] Among them, if two detection tasks Task a 、Task b Can be performed simultaneously without interfering with each other, then Task a 、Task b The serial numbers are unified into a or b; a∈[1,M], b∈[1,M], a≠b;

[0083] If a certain detection task a Will interfere with another detection task b , then keep Task a 、Task b The serial number remains unchanged;

[0084] S314, using the updated sequence as a detection sequence table;

[0085] If a sequence number in the detection sequence table corresponds to multiple detection tasks, it means that the multiple detection tasks need to be sent to the acquisition terminal board to be tested at the same time.

[0086] Then, the detection sequence table completes the optimization work of parallelizing the tasks that do not interfere with each other and keeping the interfering tasks independent.

[0087] S32, sending a detection task to the acquisition terminal board to be tested according to the detection sequence table;

[0088] Among them, after the detection task corresponding to the previous sequence number is completed, the detection task corresponding to the next sequence number is sent, which ensures that there is no interference between interfering tasks.

[0089] In addition, step 4 can be added, where the inspection tool obtains the corresponding inspection results after each inspection task in the inspection task set is completed and sends them back to the host computer. In addition, the host computer can further analyze the inspection results to determine whether there is an abnormality and quickly locate the abnormal location for easy maintenance.
