[0016] like Figure 1 As shown, the utility model discloses a display EDID and power automatic detection system, which includes a test host and an assembly line for transporting the machine to be tested. The assembly line is controlled by an assembly line PLC and is provided with a detection station.
[0017] The test host is connected to the EDID detection fixture via the first switch, the test host is connected to the power meter that measures the display power value via the second switch, and the test host is connected to the entry and exit fixture box via the third switch; the first and third switches are mutually exclusive switches; the exit fixture box is connected to the assembly line body PLC; the EDID detection fixture is connected to the signal line automatic plug-in system, which controls the plugging and unplugging of the test signal line and the device to be tested;
[0018] Furthermore, a collector plate number card and serial number are fixed on the collector plate of the machine to be tested, and a DCT device for reading the collector plate barcode is provided on the side of the assembly line body corresponding to the collector plate number card.

[0019] Furthermore, a blocker is provided at the exit end of the detection station, and infrared sensors for detecting the machine to be detected are provided at both ends of the detection station. The blocker and the infrared sensor are connected to the assembly line PLC.
[0020] Furthermore, the entry and exit fixture boxes and the power meter are connected to the test host through the serial port, and the EDID detection fixture is connected to the test host through the parallel port.
[0021] Furthermore, the assembly line body PLC is connected to the warning light and the blocker respectively.
[0022] Furthermore, the test host is a personal computer, a tablet, or a workstation.
[0023] The utility model adopts the above technical solution, the detection system
[0024] As possible implementation methods, the present invention supports three working modes, which can be selected according to actual conditions. The specific descriptions are as follows:
[0025] 1) EDID detection only. In this operating mode, the inlet and outlet fixture box does not need to be connected. The third switch is open and the first switch is closed. The monitor EDID is detected by the EDID detection fixture in a loop.
[0026] Specifically, as a standard test method, the system checks whether a monitor is connected. If a connection is detected, it begins reading the monitor's EDID and uses an algorithm to determine whether the EDID is correct. If the EDID is correct, a "PASS" message is displayed, and a signal is sent to the device to control the blocker to lower, allowing the monitor to exit the test station. If the EDID is incorrect, a "FAIL" message is displayed, and an alarm is triggered to prompt the operator to resolve the issue.
[0027] 2) Power testing only. In this operating mode, the EDID test fixture does not need to be connected. The third switch is closed, and the first switch is open. After receiving the entry signal, the entry / exit fixture box notifies the test host to control the power meter to measure the display's power value. Specifically, after a certain waiting time, the power meter sends a command, and the power meter returns the power value to the test program. The program then determines whether the test value meets the test specifications. If so, it displays PASS and sends a signal through the entry / exit fixture box to the equipment to control the blocker to lower, allowing the machine to exit the test station. If not, FAIL is displayed and an alarm is issued to prompt the operator to handle the problem.
[0028] 3) EDID and power are detected simultaneously. In this working mode, there is no need to connect the entry and exit fixture box, the third switch is disconnected, and the first switch is closed. The EDID detection fixture is used to detect whether the display is connected in a loop. If a connection is detected, the display EDID is read, and the algorithm is used to determine whether the EDID is correct. An instruction is sent to read the power value to determine whether the power value is within the specification range. If the EDID is correct and the power value meets the specification, PASS is displayed, and a signal is sent to the device to control the blocker to descend, and the machine flows out of the detection station. Otherwise, FAIL is displayed, and an alarm is triggered to prompt the operator to handle it. The description of the above working mode is only used to show that the specific structure of the utility model can achieve the technical effect of a set of equipment to perform multiple test items.
[0029] The utility model adopts the above technical solution. The test host is connected to the EDID detection fixture through the first switch, the test host is connected to the power meter for measuring the power value of the display through the second switch, and the test host is connected to the entry and exit fixture box through the third switch; the first switch and the third switch are mutually exclusive switches; only one set of detection equipment is required to freely switch to detect EDID or display power value, streamlining the detection system and saving manpower and material resources.
