Description

TECHNICAL FIELD

[0001] The utility model relates to security check device technical field, concretely relates to a security check judge picture keyboard with universality. BACKGROUND

[0002] The security check machine is an electronic device that completes the inspection by means of the conveyor belt to send the checked luggage into the X-ray inspection channel. When the luggage enters the X-ray inspection channel, it will block the package detection sensor, and the detection signal is sent to the system control part to generate an X-ray trigger signal to trigger the X-ray source to emit an X-ray beam. A fan-shaped X-ray beam passing through the collimator penetrates the inspected objects on the conveyor belt, and the X-rays are absorbed by the inspected objects, and finally hit the dual-energy semiconductor detector installed in the channel. The detector converts the X-rays into signals, and these weak signals are amplified and sent to the signal processing machine box for further processing. During the security check process, the security check machine system usually needs to be matched with a security check machine keyboard, which is mainly responsible for the control of the security check machine, the processing of the scanning image, and the operation of the security check operation system software. The general keyboard used by the ordinary computer is not convenient for direct correspondence with the functions of the security check equipment, and cannot meet the control requirements of the security check machine, so it is necessary to independently develop a security check keyboard according to the control functions of the security check machine.

[0003] For example, the patent document with the announcement number CN 207133784U discloses a security check machine special keyboard, which includes a keyboard shell, a fingerprint instrument, an emergency stop button and a key. The fingerprint instrument is arranged on the keyboard shell and is used to verify and manage the login permission of the security check staff. The emergency stop button is arranged on the keyboard shell and is used to control the pause of the security check machine work. The key is arranged on the keyboard shell. This technical solution verifies and manages the login permission of the security check staff through the setting of the fingerprint instrument, which is convenient for the security check staff to log in through the keyboard to control the security check machine work, and further verifies and manages the identity information of the security check staff through the fingerprint instrument, so that the security check is more safe and reliable.

[0004] The above technical solution can solve the technical problem that the keyboard matched with the security check machine in the prior art has poor safety and is difficult to cooperate with the security check machine to form a safe and reliable security check system. However, in the above technical solution, in order to improve the convenience of the security check keyboard operation, only the keys for controlling the conveyor belt and image processing are arranged in the security check keyboard, which leads to the single function of the security check keyboard and the inability to realize the functions other than the security check process control. When other operations need to be performed on the security check machine or the workstation (such as monitoring equipment), the external keyboard needs to be used for operation, which is not convenient for the daily use and maintenance of the security check machine.
