[0031] This equipment uses a PCI bus controller. According to the system test task requirements, the operating control system first performs a self-check of the equipment.

[0035] In the above technical solution, the keyboard fixing buckle 11 is used to fix the keyboard 3 on the front side of the device housing 1. The setting of the metal hinge 4 allows the keyboard 3 to be movable, thereby ensuring the storability of the keyboard 3. When the keyboard needs to be used, the keyboard fixing buckle 11 is released to fix the keyboard 3, and the keyboard 3 is flipped to a vertical state with the device housing 1, and the keyboard 3 can be used to perform related operations.

[0036] This arrangement makes it very convenient to store the keyboard 3, and there is no need to carry a keyboard with you.

[0037] Specifically, a heat dissipation portion 5 is provided on one side of the device housing 1, a power status observation column 6 is provided at the bottom of the heat dissipation portion 5, a USB interface 7 is provided on the side of the power status observation column 6, a switch 8 is provided on the other side of the device housing 1, a network cable interface 9 is provided on the side of the switch 8, and a handle 12 is fixedly installed on the top of the device housing 1.

[0039] Such arrangement makes the whole device easy to install, light and easy to operate, light in size and easy to carry.

[0040] Specifically, the keyboard fixing buckle 11 includes a keyboard fixing seat 111 fixedly connected to the device housing 1, a synchronization bar 112 is provided on the front of the keyboard fixing seat 111, a telescopic column 113 is fixedly installed on one side of the back of the synchronization bar 112, and the other end of the telescopic column 113 is fixedly connected to the front wall of the device housing 1, a synchronization column 114 is fixedly installed on the other side of the back of the synchronization bar 112, the other end of the synchronization column 114 passes through the front wall of the keyboard fixing seat 111 and is fixedly connected to a limiting spring 115, a synchronization plate 116 is fixedly installed on the side of the synchronization column 114, the other end of the synchronization plate 116 passes through the inner side wall of the keyboard fixing seat 111 and is fixedly connected to a connecting rod 117, the other end of the connecting rod 117 is hinged to a limiting seat 118, a sliding block 119 is fixedly installed on the back of the limiting seat 118, the other end of the sliding block 119 is slidably connected to the keyboard fixing seat 111, a spring rod 120 is fixedly installed on the side of the limiting seat 118, and the other end of the spring rod 120 is fixedly connected to the limiting plate 121.

[0041] In the above technical solution, when the keyboard 3 needs to be stored, the keyboard 3 is flipped to the front of the synchronization bar 112 and the synchronization bar 112 is pressed. The telescopic column 113 is set to ensure the stability of the synchronization bar 112 during movement. The synchronization column 114 moves synchronously, thereby driving the synchronization plate 116 to move, thereby driving the connecting rod 117 to move. The connecting rod 117 then converts the vertical movement of the synchronization plate 116 into the horizontal movement of the limit seat 118, and the limit plate 121 then moves toward the direction of the keyboard 3 until it moves to the front of the keyboard 3, thereby achieving fixed limit of the keyboard 3.

[0042] The setting of the spring rod 120 allows the limit plate 121 to have a certain adjustable range, so that when the limit plate 121 is released from limiting the keyboard 3, it is only necessary to manually move the limit plate 121 in a direction away from the keyboard 3. After the limit plate 121 is released from limiting the keyboard 3, the keyboard 3 can be flipped to a state perpendicular to the device housing 1. Under the action of the limit spring 115, the synchronization bar 112 will be reset synchronously, thereby facilitating the subsequent continued limiting.

[0043] The sliding block 119 is used to connect the keyboard fixing seat 111 and the limiting seat 118 , so as to ensure the stability of the limiting seat 118 when moving, and also play a certain limiting role on the limiting seat 118 .

[0044] When in use and testing, the loading and unloading switching mechanism first completes a series of mechanical actions such as loading and unloading according to the test requirements. The test system outputs a control signal corresponding to the detection task, and the test product completes the specified action according to the instruction requirements. Each signal is output to the data acquisition component through the electrical interface, and under the control of the computer, data is collected for each action signal, instruction information, and each analog and digital variable from the beginning of work. The data is received by the controller module and the computer, and finally stored and processed in real time by the computer control system, and the processing results are displayed at the same time.

[0045] The keyboard fixing buckle 11 is used to fix the keyboard 3 on the front side of the device housing 1. The setting of the metal hinge 4 allows the keyboard 3 to be movable, thereby ensuring the storability of the keyboard 3. When the keyboard needs to be used, the keyboard fixing buckle 11 is released to fix the keyboard 3, and the keyboard 3 is flipped to a vertical state with the device housing 1, and the keyboard 3 can be used to perform related operations.

[0046] When the keyboard 3 needs to be stored, the keyboard 3 is flipped to the front of the synchronization bar 112 and the synchronization bar 112 is pressed. The telescopic column 113 is set to ensure the stability of the synchronization bar 112 during movement. The synchronization column 114 moves synchronously, thereby driving the synchronization plate 116 to move, thereby driving the connecting rod 117 to move. The connecting rod 117 then converts the vertical movement of the synchronization plate 116 into horizontal movement of the limit seat 118, and the limit plate 121 then moves toward the direction of the keyboard 3 until it moves to the front of the keyboard 3, thereby achieving fixed limit of the keyboard 3.

[0047] The setting of the spring rod 120 allows the limit plate 121 to have a certain adjustable range, so that when the limit plate 121 is released from limiting the keyboard 3, it is only necessary to manually move the limit plate 121 in a direction away from the keyboard 3. After the limit plate 121 is released from limiting the keyboard 3, the keyboard 3 can be flipped to a state perpendicular to the device housing 1. Under the action of the limit spring 115, the synchronization bar 112 will be reset synchronously, thereby facilitating the subsequent continued limiting.
