Abstract

The invention discloses a wireless device testing method based on a wireless ad hoc network. In the method, a test controller, a detecting wireless device connected with the test controller and a plurality of wireless devices to be detected are comprised in an applied hardware environment, wherein the wireless devices to be detected are respectively connected with the detecting wireless device; the test controller is used for controlling the detecting wireless device to broadcast a network grouping message to all the wireless devices to be detected; the detecting wireless device is used for allocating time slots for the wireless devices to be detected, which receive the network grouping message and then reply response messages, and testing the performances of the wireless devices to be detected in respective allocated time slots; after testing, the detecting wireless device reports the performance testing result information of all the wireless devices to be detected to the test controller; and the test controller displays the received performance testing result information. By using the wireless device testing method disclosed by the invention, the product testing speed and efficiency are greatly improved, and a large amount of time cost and manpower cost are greatly saved.

Example Embodiment

[0024] Some embodiments of the invention are described in detail below. However, the invention can also be widely practiced in other embodiments than these embodiments, and the scope of the invention should not be limited by them, but should be determined by the appended claims.

[0025] figure 1 It is a schematic diagram showing the wireless device batch test solution described in the present invention, including some basic equipment and connection methods described in the present invention. The equipment involved in the test includes a PC, a detection device, and several wireless devices to be tested. Before the wireless device under test enters the test process, if the device itself does not have an ID, it is necessary to pre-configure the ID of each device in the firmware. . The testing equipment should be the same type of equipment that does not need to be tested and has the same or similar performance as the tested equipment. The testing equipment should have a serial port or a general interface that can interact with a PC. This solution uses a serial port as an example. Then enter the testing process.

[0026] 1) Connect the testing device to the PC through the serial port, place a number of tested wireless devices that have been configured with IDs around the testing device, and use the test software running on the PC or directly use the PC serial port debugging assistant to issue a command to start the test ;

[0027] 2) When the PC issues the start test command and the detection device receives the start test command, the detection device will broadcast an ad hoc networking frame to all the tested devices through the wireless module, and the tested device receives the network frame The response message will be replied in CSMA-CA mode. In order to solve the packet loss problem, the process will use a three-way handshake mechanism until the interaction is successful or the maximum number of times that cannot be tolerated is reached. Since the wireless performance of the test equipment and the equipment under test is the same, if the performance of the equipment under test is good, the above process should be completed, and finally a star-shaped wireless ad hoc network is formed. If the test item includes a self-test performance test, the result of the self-test performance test should also be included in the response message during the networking process;

[0028] 3) The detection device allocates a time slot for the device under test that replies to the response message. The standard of the time slot length is n*t (n>=2), and t represents the time length for a complete test. The detection device starts slot scheduling at the same time;

[0029] 4) The detection device and each device under test will conduct a wireless transmission and reception performance test in the corresponding time slot, generally including the wireless signal strength test, loss Packet rate test, bit error rate test, etc. If a test result can be obtained in the testing device, it will be generated directly by the testing device; if a test result is obtained in the device under test, the device under test will send the test result in the form of wireless frames after the test Report to the test node;

[0030] 5) After the test is completed, the testing equipment will report to the PC the results of the self-test performance test of each tested equipment and the wireless transmission and reception performance results of the tested equipment obtained in the time slot communication between the testing equipment and the tested equipment;

[0031] 6) Finally, the software running on the PC will receive the data and reflect the result in the form of text or image.

[0032] It should be noted that because wireless communication has relatively high requirements on the environment, the wireless performance of wireless devices in different environments is not completely the same. For example, the wireless performance of devices in open areas is better, but the wireless performance environment in areas with severe occlusion such as laboratories is generally poor. Therefore, for different test environments, the requirements for test results are also different. So there are two possible options:

[0033] (1) On the PC, only the data results are given without giving the final judgment result (the tested equipment is good or bad);

[0034] (2) Give the final judgment result, but provide the dynamic setting of the test standard.

[0035] Due to the inherent uncertain characteristics of the self-organizing network itself, a single test failure does not completely mean that the equipment is unqualified. Or if it fails more than two times, it is determined that the equipment is unqualified and enters the repair, rework or elimination process.

[0036] The description and application of the present invention herein is illustrative, and is not intended to limit the scope of the present invention to the above-described embodiments. Variations and variations of the embodiments disclosed herein are possible, and alternative and equivalent various components of the embodiments are known to those of ordinary skill in the art. It should be clear to those skilled in the art that the present invention can be realized in other forms, structures, arrangements, proportions, and with other elements, materials and components without departing from the spirit or essential characteristics of the present invention.
