The simulation of an actual scene can be realized, and serial port data communication can be carried out with the module.
The USB Dongle is used for connecting the wireless communication module to be tested and detecting whether the wireless communication connection and the data transmission function of the wireless communication module are normal.
The PC upper computer is used for operating the USB Dongle, starting an automatic detection process and recording a detection result.
The automatic detection tool for the wireless communication module can detect whether the wireless communication module normally works or not, has the characteristics of high accuracy, high detection efficiency, high automation degree and the like, saves the cost, improves the detection flexibility and ensures the lower defective rate of the wireless communication module.
Fig. 3 is a flowchart of an automated detection method of a wireless communication module according to an embodiment of the invention.
The detection method comprises the following steps:
s1, opening the PC upper computer, and plugging a USB Dongle;
s2, placing the wireless communication module on a test rack, and sending broadcast data to the PC upper computer by the wireless communication module;
s3, sending a connection request to the wireless communication module by the PC upper computer and establishing connection;
s4, sending test data to the wireless communication module by the PC upper computer;
s5 the wireless communication module receives the test data and transmits the test data to the MCU on the test rack;
s6, after receiving the test data, the MCU on the test rack returns the test data to the wireless communication module;
s7 the wireless communication module transmits the returned test data to the PC upper computer;
s8 the PC upper computer receives the returned test data, judges whether the returned test data is correct, if the returned test data is correct, the test is considered to pass, the wireless communication connection and data transmission function of the wireless communication module are normal, and the detection is finished; if the returned test data is wrong, the test is not passed, the wireless communication connection and the data transmission function of the wireless communication module are abnormal, and the detection is finished.
Here, the S8 step further includes: if the test is passed, the PC upper computer sends a test passing message to the wireless communication module, the wireless communication module forwards the received test passing message to the MCU of the test jig, the MCU of the test jig lightens the LED lamp on the test jig after receiving the test passing message, a tester clearly knows that the wireless communication connection and data transmission functions of the wireless communication module are normal, and the wireless communication module is qualified; if the test data returned in the step S8 is wrong, the test is not passed, the LED lamp on the test rack is not lighted, and the inspector knows clearly that the wireless communication connection and the data transmission function of the wireless communication module are abnormal, and the wireless communication module is not qualified.
In the detection method, after the test is successful, an operator takes the module down, puts a new module on the module, powers on the module and restarts the detection.
Here, the S4 step further includes: the PC upper computer sends test data to the wireless communication module, and if the wireless communication module can receive the test data sent by the PC upper computer within 3 seconds, the step S5 is carried out; if the wireless communication module can not receive the test data sent by the PC upper computer within 3 seconds, the test is failed to end.
When a plurality of wireless communication modules need to be detected simultaneously, a plurality of USB Dongle modules can be inserted simultaneously. The PC upper computer can automatically expand the interface, simultaneously display a plurality of detection interfaces and simultaneously operate a plurality of USB Dongle to detect the wireless communication module. Compared with the time-sharing multiplexing of one USB Dongle, the time required is greatly reduced. When a plurality of USB dongles operate simultaneously, due to the randomness of the broadcast of the wireless communication module, the situation that the plurality of USB dongles search for the same wireless communication module at the same time may occur, if the PC host computer does not perform special processing at this time, but directly initiates connection, the situation that the plurality of dongles simultaneously connect the same wireless communication module can be caused, at this time, one Dongle can be successfully connected, but another Dongle can be unsuccessfully connected and starts connection overtime. This greatly increases unnecessary time and also loses the meaning of using multiple USB dongles simultaneously.
In order to solve the above problem, the step of S3 further includes: before sending a connection request to the wireless communication module, the PC upper computer detects whether the address of the wireless communication module is registered in an address manager (whether the address of the wireless communication module is connected or not), and if not, immediately registers the address and establishes connection; if yes, the address is ignored, and a new wireless communication module is reconnected.
When the detection is finished, the PC upper computer releases the address of the wireless communication module (disconnection), so that other USBDongles or the PC upper computer can operate the module again.
In the operation that a plurality of wireless communication modules detected simultaneously, the LED lamp on the test jig can let the convenient module that has a problem of distinguishing of operator.
The PC upper computer can automatically record the detection result, and the record comprises time, module Bluetooth address, firmware version number, hardware version number and the like. Two tables are derived for each detection result, namely a table with passed detection and a table with failed detection. Meanwhile, the detection record can be added into a system production record database. The database can inquire the information such as the total number of the production modules, the batch, the detection result of each module and the like.
The automatic detection system for the wireless communication module can detect whether the wireless communication module normally works or not, has the characteristics of high accuracy, high detection efficiency, high automation degree and the like, saves the cost, improves the detection flexibility and ensures the lower defective rate of the wireless communication module.
Further, in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.
In the description herein, references to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention.
