Problems solved by technology

However, it takes a long time to simulate a high and low temperature cycle state in the high and low temperature test box. During batch testing, several image time synchronization controllers must be tested in the high and low temperature test box, and the high and low temperature cycle in the high and low temperature test box must be completed. Do it several times, which will result in low test efficiency of the batch image time synchronization controller

Embodiment 1

[0026] The image time synchronization controller 4 is one of the important hardware of the TDS intelligent dry selection machine, and is the core device of the image recognition system, and is mainly used for the time synchronization trigger of the image recognition system.

[0027] When the image time synchronization controller 4 is in use, an image signal is sent to the image time synchronization controller 4 through the image collector, so that the image time synchronization controller 4 performs image processing. Moreover, the image time synchronization controller 4 is generally used in an environment with a large temperature difference. In order to ensure normal use, a high and low temperature test must be used to simulate the use environment with a large temperature difference before use, and the image signal transmission of each interface of the image time synchronization controller 4 is tested. Is it normal.

[0028] In the conventional test, a single image time synchr...

Embodiment 2

[0067] Such as image 3 As shown, the present embodiment provides a method for testing an image time synchronization controller. Using the image time synchronization controller test tool of the first embodiment above, multiple image time synchronization controllers 4 can be tested. During the image signal transmission process, the switch 3. According to whether the image signal can be transmitted normally, determine the working status of each transmission interface of each image time synchronization controller 4 in turn. The image signal is the image signal sent by the image collector to the first image time synchronization controller 4 . The method includes:

[0068] The premise of the test is that each port of the switch 3 can transmit signals normally. The upper computer 7 can read the state of each port of the switch 3 to judge whether the transmission interface of the image time synchronization controller 4 connected to the port can transmit normally.

Abstract

The invention provides an image time synchronization controller test tool and a test method thereof, and belongs to the technical field of interface test. An image time synchronization controller is internally provided with a processor, and a first-stage transmission input port, a first-stage transmission output port, a second-stage transmission input port and a second-stage transmission output port which are electrically connected with the processor; the tool comprises a power supply, an image collector, a switch, an upper computer and a high-low temperature test box, and a plurality of imagetime synchronization controllers are located in the high-low temperature test box; the image collector is electrically connected with the first image time synchronization controller and sends an image signal to the first image time synchronization controller, and the image time synchronization controller feeds back the image signal to the switch; the switch sends and receives image signals to andfrom the subsequent image time synchronization controller in sequence; and the upper computer is electrically connected with the switch, and the upper computer receives image signals fed back by theplurality of image time synchronization controllers through the switch. Cascade testing of a plurality of image time synchronization controllers is realized, and the testing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of interface testing, in particular to an image time synchronization controller testing tool and a testing method thereof. Background technique [0002] The image time synchronization controller is used to process image information, and the image signal is sent to the image time synchronization controller through the image collector, so that the image time synchronization controller can perform image processing. When in use, the image time synchronization controller is generally used in an environment with a large temperature difference, so before use, it is necessary to test whether the signal transmission of each interface of the image time synchronization controller remains normal in an environment with a large temperature difference. [0003] Generally, high and low temperature tests are used to simulate the use environment with large temperature differences. The image time synchronization controller is ...
