Description

Technical Field

[0001] The present invention relates to security inspection technology, in particular to a control system of an integrated security inspection and disinfection machine. Background Art

[0002] Luggage inspection machines are electronic devices that use a conveyor belt to transport inspected luggage into an X-ray inspection tunnel. When luggage enters the X-ray inspection tunnel, it blocks the package detection sensor. The detection signal is transmitted to the system control unit, generating an X-ray trigger signal, which triggers the X-ray source to emit an X-ray beam. A fan-shaped X-ray beam, passing through a collimator, passes through the inspected items on the conveyor belt. The X-rays are absorbed by the items and ultimately strike a dual-energy semiconductor detector mounted within the tunnel. The detector converts the X-rays into signals, which are amplified and sent to a signal processing unit for further processing. Due to increasing demand, some locations require the disinfection of luggage surfaces, but conventional luggage inspection machines do not have this capability. Summary of the Invention

[0024] Reference Figure 1 and Figure 2 and, this embodiment provides a control system for a security inspection and disinfection integrated machine, including: an AC input part, a security inspection module, a disinfection module, a PLC central control, an operation panel, and an AC contactor;

[0025] The power supply end of the security inspection module is connected to the AC input part through the AC contactor; the PLC central control outputs a control signal to control the on / off of the AC contactor;

[0026] The power supply end of the disinfection module is connected to the AC input part, and the control end is connected to the PLC central control to separately control the individual disinfection factors in the disinfection module to work independently through the PLC central control;

[0027] The operation panel is connected to the signal input end of the PLC central control to receive external input instructions;

[0028] A communication protocol is established between the PLC central control and the security inspection module to obtain the operating parameters of the security inspection module.

[0029] In use, the user inputs instructions through the operation panel. By controlling the on / off of the AC contactor, the connection or disconnection between the security inspection module and the AC input part can be achieved, thereby controlling the start and stop of the security inspection module. Moreover, the security inspection module can also feedback the current operating parameters, such as the linear speed of the conveyor belt roller and the number of passing items, to the PLC central control. The PLC central control can also set the above-mentioned operating parameters to achieve the control of the security inspection module. For the disinfection module, the PLC central control can control the working states of various disinfection factors according to different disinfection factors, such as power, time, etc.

[0030] In this embodiment, the disinfection factors include UV LED, UV mercury lamp, photocatalyst, negative ion, and plasma. The user can select one or several disinfection factors according to needs to achieve the disinfection of goods.

[0031] In this embodiment, the AC input part includes an AC power supply and a circuit breaker. The input end of the circuit breaker is connected to the AC power supply, and the output end is respectively connected to the power supply ends of the AC contactor, the disinfection module, and the PCL central control. The circuit breaker can be disconnected in case of a fault, thereby disconnecting the AC power supply from the disinfection module and avoiding electrical accidents.

[0032] In addition, in this embodiment, a sensor is further included. The signal output end of the sensor is connected to the signal input end of the PLC central control. The sensor includes an ozone sensor and a UV illuminance sensor, so as to monitor the strength of the disinfection factors in the disinfection chamber in real time, and thus determine whether to turn on or off the corresponding disinfection factors. This can be targeted and ensure the maximization of the disinfection effect.

[0033] Moreover, the disinfection module further includes a current transformer, which is correspondingly arranged with the disinfection factor and is used to judge whether the corresponding disinfection factor is working normally. In this way, it can be timely detected whether there is a fault in the disinfection factor, and it is displayed or alarmed on the control panel, so that the user can timely repair and eliminate the fault.

[0034] In order to facilitate the monitoring and recording of multiple all-in-one machines, the PLC central control establishes a data connection with the cloud platform through network port communication or cellular network communication. In this way, the cloud platform can simultaneously obtain the data of multiple all-in-one machines for monitoring.

[0035] Finally, in this embodiment, the signal transmission between the sensor and the PLC central control, and between the security inspection module and the PLC central control is carried out through RS485 signals.

[0036] As described above, it is only the preferred specific implementation manner of the present invention. However, the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention who makes non-substantial modifications to the present invention using this concept shall fall within the scope of infringement of the protection scope of the present invention.
