Embodiment 1

[0032] refer to figure 1 , the present embodiment provides a multi-threaded test system for car audio, including an equipment cabinet 7 and a test rack one 1, a test rack two 2, a test rack three 3, a test rack four 4, and a test rack located inside the equipment cabinet. Rack five 5, test rack six 6, darkroom 8 and moving rails. The equipment cabinet 7 is equipped with a terminal main control device, and a touch screen device can be installed on the equipment cabinet, and the staff can directly control the operation of the entire system through the touch screen.

[0033] The darkroom 8 is located on the table top inside the equipment cabinet 7, and a row of test racks is respectively arranged on both sides of the darkroom, and each row has three test racks. Wherein, test rack one 1, test rack three 3, test rack four 4 and test rack six 6 enter or exit the darkroom through arc guide rail 9, arc guide rail 11, arc guide rail 12 and arc guide rail 14 respectively 8. Test rack ...

Embodiment 2

[0038]This embodiment provides a terminal main control device of a car audio multi-thread test system, which can be used in the car audio multi-thread test system in Embodiment 1. The main control device of the terminal includes a communication bus module, a signal generation module, a transfer and signal distribution module, a data acquisition module, a visual test module, a motion control module, a PLC control module and a DIO module.

[0039] like figure 2 As shown, the modules on each test rack that realize the communication connection with the terminal main control device include a communication module, a functional input and output interface and an RF module. The communication module is used to transfer the communication line between the product to be tested and the communication bus module; the RF module is used to receive and transfer function signals, radio signals and high-frequency signals; the function input and output interface is used for the product to be teste...

Embodiment 3

[0047] This embodiment provides the operating method of using the car audio multi-threaded test system in Embodiment 1 to carry out the test work, refer to image 3 and Figure 4 , when the system works normally, the product starts from the initial state 100, enters the normal production state 101 and runs until the end of 106, and then returns to the initial state 100 to replace the product; Circulate until all products are tested, and the system returns to the initial state 100.

[0048] Specifically include the following steps:

[0049] S1. Turn on the test system and initialize system public hardware resources.

[0050] S2. Create six threads, each thread corresponds to an independent work station, and initialize the test racks of each station.

[0051] S3. Each station performs power-on operation on the products placed on the station, and the corresponding image 3 The system working status in 100.

[0052] S4. The test rack 1 receives the optical test signal, the te...

Abstract

The invention provides a multi-thread testing method for automobile acoustics, which comprises the following steps of: initializing system resources; a plurality of threads are created, each thread corresponds to a test station which works independently, hardware resources of each station are initialized, and the product under test can complete all test contents except optical test in one test station; after the products are powered on at each station, the products at each station receive signals and enter the optical test station in sequence, and the products that have not been allowed to enter the optical test station shall first execute other functional test items at the station; the product that completes the optical test exits the optical test station and returns to the correspondingstation for other test contents; upon completion of product testing at all stations, replacing a new batch of products to be tested and proceed to the next round of testing, continuously cycling untilall products have been tested. The invention also provides a multi-thread test system for carrying out test work by using the method, which has the advantages of simple operation, high work efficiency, saving manpower and material resources and wide application.

Description

technical field [0001] The invention belongs to the field of automobile electronic products, and in particular relates to a multi-thread test method and a test system for car audio. Background technique [0002] With the vigorous development of the car audio industry, the structure of the car audio is becoming more and more complex and precise, and the requirements for the test system of the car audio are also getting higher and higher. In the traditional production mode of modern car audio products, the whole machine test system, ring automatic line test system and simple multi-thread parallel test system are usually used. The whole machine test mode requires more systems and operators, and the degree of automation is low, time-consuming. Manual, and many systems will result in a large footprint and low utilization of system resources. The ring automatic line test mode has a high degree of automation, which saves labor and improves work efficiency, but it has the disadvant...
