The sorting method of the security check package realized by the security check package sorting system comprises the following steps:

1) all the conveyor belts are started to work except the sub-conveyor belt 31 of the distributor, and the packages 18 are placed on the front-end conveyor belt 1 and conveyed to the conveyor belt 2 of the security inspection machine by the front-end conveyor belt 1.

2) When the package is detected by G1, G1 is triggered, the camera 5 shoots an outline drawing of the package, and meanwhile, the distribution controller controls the displacement sensor to acquire displacement data of the conveyor belt 2 of the security inspection machine as first distance data T1 of the package; when the package leaves G1, the distribution controller controls the displacement sensor to acquire displacement data of the conveyor belt 2 of the security inspection machine as second distance data T2 of the package; when the package is detected by G2, G2 is triggered, and the security check machine controller controls the X-ray generator to work to scan the package; when the parcel leaves G2, the security check machine controller controls the X-ray generator to be closed, and the parcel scanning is finished.

3) The DP processes the information collected by the linear detection array and transmits the information to the security check computer 7, and the security check computer 7 generates a perspective view of the package according to the information collected by the linear detection array; and transmitting the generated perspective view to a pattern recognition server; the image recognition server recognizes the image, judges whether the image is a dangerous article or not, and identifies the package if the package is the dangerous article; the pattern recognition server returns the identification result (identification result is identification and no identification) to the security check computer 7, and the security check computer 7 records the identification state of the package.

4) If the package is not identified, the package is normal, the security check computer 7 sends a release instruction to the distribution controller, and the T1 and T2 information of each package in the queue is cleared; if the package is marked, the package is indicated as a dangerous article, the security check computer 7 sends a distribution instruction to the distribution controller, the distribution controller G3 is started, the latest T1 is selected as the initial distance of the dangerous article, and the latest T2 is selected as the tail end distance of the dangerous article. Meanwhile, the security check computer 7 sends the appearance diagram of the package shot by the latest camera 5 to the rechecking machine as the appearance diagram of the dangerous goods.

In this step, the allocation and release command is sent in a manual intervention mode, an allocation and release selection frame is displayed in the security check computer 7, and when the identifier is wrapped, the allocation is clicked, and an allocation instruction is sent; and when the package has no mark, clicking to release, and sending a release instruction.

Of course, the distribution controller sends the collected T1 and T2 to the security check computer 7, and the security check computer 7 calculates the length of each parcel according to T2-T1; and records the trigger time, profile, T1, T2, and T2-T1 of the package. And all the information of the package recorded by the security check computer 7 is sent to the rechecker.

5) When the package is detected by G3, G3 is triggered, the distribution controller controls the displacement sensor to output displacement data, the displacement data are used as third distance data T of the package, the distribution controller judges whether T-TL is equal to T1(TL is the distance between G3 and G1), if not, the triggered package is a non-dangerous article, and the package is released continuously; if the value is equal to the value, it indicates that the dangerous goods trigger G3 (i.e. the package corresponding to the third distance data is a dangerous goods), and the triggered package is the package to be pushed.

6) The allocating controller calculates the length of the dangerous goods according to the latest T1 and the latest T2:

if the length of the dangerous goods is larger than a package length threshold value (the package length threshold value is the maximum pushing length of the distributor), the safety inspection machine conveying belt 2 and the distributor conveying belt are controlled to stop, and the indicator lamp 6 changes from yellow to red to flicker (red light flicker indicates that manual treatment is needed); after manual treatment, pressing a switch K5 to control the security inspection machine conveyor belt 2 and the distributor conveyor belt to continue to operate;

The switch K and the switch KZ2-1 are closed, and M2 is started; when the safety inspection machine conveying belt 2 needs to stop working temporarily, the control switch KZ2-1 is switched off, and when the safety inspection machine conveying belt 2 needs to continue working, the control switch KZ2-1 is switched on after the switch K5 is pressed.

The working state of the main conveyor belt 3 of the allocating machine is controlled by M3, a control loop of M3 is shown in figure 6, a switch KZ3-1 (the control of the switch KZ3-1 is realized by a control coil KZ3, the control of the control coil KZ3 is realized by a control command sent by an allocating controller as shown in figure 9) and a switch K1 are connected in series on a power supply line of M3, and Kz3-1 is the switch control output of the allocating controller and is in a non-instantaneous state; the switch K1 is a position switch of the pushing plate 11, is a normally closed switch, when the pushing plate 11 is at the initial position, the K1 is in a closed state, and at the moment, the operation or stop of M3 is controlled by KZ 3-1; when the dangerous goods trigger G4, the allocating controller controls the KZ3-1 to be disconnected, the M3 is powered off, and the main conveying belt 3 of the allocating machine stops working.

7) The distribution controller controls the pushing device to enter a pushing program, and controls the indicator lamp 6 to change from green to yellow (a yellow lamp indicates that dangerous goods processing work starts). When the state of G3 is changed from blocking to passage, the package is completely sent to the conveyor belt of the allocating machine, the conveyor belt 2 of the security inspection machine is controlled to stop working, and the indicator light 6 is changed from yellow to red (here, the red light does not flicker, and indicates that pushing is about to start, but does not need manual processing).

8) When G4 detected the parcel, when G4 was triggered, the hazardous articles reached the propelling movement position, and the main conveyer belt 3 stop work of allocation controller control allocation. After the main conveying belt 3 of the distributor stops working, the pushing motor M5 is controlled to work, and the pushing device is started; when the pushing plate 11 pushes the dangerous goods in place (here, the dangerous goods are pushed to the sub-conveyer belt 31 of the allocating machine), the pushing plate 11 is controlled to reset, and the sub-conveyer belt 31 of the allocating machine is controlled to work.

When the pushing plate P leaves the initial position and the dangerous goods are pushed, the switch K1 is actuated to change the normally closed state into the open state, and the M3 can be locked, so that the M3 is always in the power-off state.

The working state of the sub-conveyer belt 31 of the allocating machine is controlled by M6, a control loop of M6 is shown in figure 8, a switch JC6-2 is connected in series on a power supply line of M6, two ends of the M6 are connected with a time relay TT1 in parallel, and the switch JC6-2 is controlled by a control coil JC 6; a switch KTT1 (i.e., a normally closed contact of the time relay TT 1) is connected in series to a power supply line of the control coil JC6, and a switch JC6-1 (the switch JC6-1 is controlled by the control coil JC 6), a switch K3, and a button KAN (manual button) are connected in parallel and then connected in series to the switch KTT 1. When the dangerous goods are pushed to the right position by the pushing plate 11, the K3 acts and is switched from open to closed, the control coil JC6 is electrified, the JC6-1 is closed, the JC6 is kept in a suction state, meanwhile, the JC6-2 is closed, the M6 is started, the sub-conveyer belt 31 of the allocating machine is used for conveying packages, and meanwhile, the time relay TT1 is electrified. The action time of the time relay TT1 is set as the time from the start of the M6 to the time when the sub conveyor belt 31 of the distribution conveyor conveys the parcels to the designated position, therefore when the time reaches the preset time and TT1 acts, the KTT1 is changed from the normal close state to the disconnection state, the JC6 coil is powered off, the JC6-1 and the JC6-2 are disconnected, the M6 stops running, the TT1 is reset, and the loop returns to the initial state.

9) When the push plate 11 is reset (that is, the switch K1 and the switch K2 are detected to be closed), the control switch KZ5-1 is switched off, the push motor M5 is powered off, the control switch KJC is switched off, and the M5 is reset to rotate forwards; meanwhile, the switch KZ3-1 and the switch KZ2-1 are controlled to be closed, and the security check machine conveying belt 2 and the distributor main conveying belt 3 run.
