Abstract

Disclosed is system, apparatus and method for centralized management of security inspection devices, which provide connection and communication between local security inspection devices and a remote control site according to bus communication scheme. The system comprises: a plurality of security inspection devices arranged on the spot; a remote control site arranged at a remote side; and a field bus network connecting the plurality of security inspection devices with the remote control site and transmitting signals between the plurality of security inspection devices and the remote control site according to bus communication scheme. With implementations of the present invention, correct and reliable centralized management of local security inspection devices from the remote control site can be achieved with less signal lines and simpler layout of the lines.

Claims

1. A system for centralized management of security inspection devices, comprising:

a plurality of security inspection devices;

a remote control site, remote from the plurality of security inspection devices, comprising

a remote control module configured to remotely control the plurality of security inspection devices in a centralized manner, and

a plurality of operation devices connected to the remote control module and configured to remotely operate the plurality of security inspection devices; and

a field bus network comprising a field bus connected to the remote control module, and a plurality of field bus branches connecting from one end of the field bus to the plurality of security inspection devices respectively, wherein the field bus network connects the plurality of security inspection devices to the remote control module, and transmits signals between the plurality of security inspection devices and the remote control module according to a bus communication scheme;

wherein

the remote control module generates at least one control signal according to an operation of at least one of the operation devices, and transmits said at least one control signal to the plurality of security inspection devices via the field bus network to thereby control at least one of the plurality of security inspection devices.

2. The system of claim 1, wherein, the field bus network comprises at least one of CAN, Profibus, Foundation Field Bus, and LON bus.

3. The system of claim 1, wherein, the remote control module transmits a control signal to the plurality of security inspection devices via the field bus network, and

each of the security inspection devices identifies the control signal, and performs a control operation according to the control signal when the control signal is identified as corresponding to the security inspection device.

4. The system of claim 1, wherein, each of the plurality of security inspection devices transmits at least one of error information, failure information, and status information to the remote control module via the field bus network, and

the remote control module receives at least one of the error information, failure information, and status information, and displays the received information.

5. The system of claim 1, wherein, a plurality of information indication devices are further provided at the remote control site, connected to the remote control module and controlled by the remote control module to indicate information of the plurality of security inspection devices, respectively.

6. The system of claim 3, wherein, the control signal comprises at least one of a power-on/off signal and an emergency stop signal.

7. The system of claim 5, wherein, the remote control module receives at least one of the error information, failure information, and status information from at least one of the security inspection devices via the field bus network, and controls to display the received information on at least one of the information indication devices corresponding to said at least one of the plurality of security inspection devices.

8. The system of claim 5, wherein, the operation devices comprise at least one of power-on/off devices, and emergency stop devices, and the information indication devices comprise status indication lights.

9. An apparatus for centralized management of security inspection devices, wherein the apparatus is arranged at a control site remote from the security inspection devices, and comprises:

12. A method for centralized management of security inspection devices, comprising:

generating, at a control site remote from a plurality of security inspection devices, at least one control signal according to an operation of at least one of the operation devices provided at the control site and configured to remotely operate the plurality of security inspection devices, respectively;

transmitting the at least one control signal to the plurality of security inspection devices via a field bus network which connects the plurality of security inspection devices with the control site; and

identifying the at least one control signal by each of the plurality of security inspection devices, and in response to the at least one control signal being identified as corresponding to the at least one of the plurality of security inspection devices, performing a control operation according to the at least one control signal.

13. The method of claim 12, wherein, at least one the control signal comprise at least one of power-on/off signal, and emergency stop signal.

14. The method of claim 12, further comprising:

transmitting at least one of error information, failure information, and status information from the plurality of security inspection devices to the control site via the field bus network; and

receiving and displaying collectively the at least one of error information, failure information, and status information at the control site.
