Abstract

The application relates to an intelligent traffic cloud control system configured to acquire and centrally analyze a large amount of field data in a traffic system, and to control the traffic system. Unlike a traditional traffic directing and controlling system in such an operating mode that data are acquired and transmitted respectively by different sensing devices, and then collected, analyzed, and processed by a central system, the intelligent traffic cloud control system according to the invention analyzes and processes centrally a large amount of data through field control servers communicating over IP address based broadband buses, and performs adaptive traffic control, traffic regulation enforcement, position tracking, coordinated control, and other service functions through integrating edge computing and cloud computing at a plurality of adjacent field control servers.

Claims

1. An intelligent traffic cloud control system, comprising:

a control server arranged at each intersection, and a plurality of IP-enabled field devices configured to communicate with the control server over an IP address based broadband bus, wherein;

the IP-enabled field devices are configured to acquire traffic intersection data; and

the control server is configured to centrally process the data acquired by the IP-enabled field devices, and to control traffic in a local area through edge computing, and/or

the control server is configured to determine that a preset trigger condition is satisfied, and if the control server is a master control server in a pre-created customized area comprising the control server, then the master control server generates a coordinated control strategy through self-learning and edge computing to perform coordinated control in the customized area; and

if the control server is a slave control server, then the slave control server acquires a coordinated control strategy from a master control server through cloud computing.

2. The system according to claim 1, wherein there is a broadband bus in one traffic direction, and for each traffic direction, the control server communicates with the IP-enabled field device in the traffic direction over the broadband bus in the traffic direction;

or

a common broadband bus is configured for all the traffic directions of an intersection, and the control server communicates with the IP-enabled field device at the intersection over the common broadband bus.

3. The system according to claim 1, wherein the customized area is consisted of local areas of a plurality of control servers adjacent in position;

and

coordinated control comprises traffic regulation enforcement, locus tracking, traffic control, and positioning of an object to be positioned.

4. The system according to claim 3, wherein the system further comprises:

a central system configured to exchange data with the plurality of control servers over a network, to share the data stored in the control servers connected therewith, and to analyze and process the shared data to obtain a result of the analysis; and

to generate a coordinated control strategy according to the result of the analysis, and to transmit the coordinated control strategy to the corresponding control servers; and

the control servers are further configured to acquire the coordinated control strategy from the central system through cloud computing, and to perform corresponding operations according to the coordinated control strategy.

5. The system according to claim 1, wherein controlling the local traffic through edge computing comprises:

analyzing and storing, by the control server, the acquired data, generating a control instruction on the IP-enabled field device, and transmitting the control instruction to the IP-enabled field device over the broadband bus for execution.

6. The system according to claim 1, wherein the customized area comprises a local area of the control server, and a local area of other specified control server than the control server;

and

performing coordinated control on the traffic in the customized area through self-learning and edge computing comprises;

sharing data of the specified control server, generating a coordinated control strategy according to the shared data of the specified control server, and controlling the traffic in the customized area according to the coordinated control strategy, wherein the control servers in the customized area store the data in a distributed manner.

7. The system according to claim 1, wherein the IP-enabled field device comprises a first IP-enabled field device and/or a second IP-enabled field device, wherein:

the first IP-enabled field device is an intelligent field device supporting the IP protocol; and

the second IP-enabled field device comprises a driver device supporting the IP protocol, and a non-intelligent field device, which does not support the IP protocol, connected with the driver device.

8. The system according to claim 7, wherein the control server is further configured to:

allocate a unique IP address for the IP-enabled field device communicating therewith.

9. The system according to claim 3, wherein the central system exchanges the data with the plurality of control servers over the network in such a way that:

the central system receives state data of the control servers in real time, and statistic and inquiry data of the control servers in a non-real time manner, and subscribes as needed to the stored data of the control servers.

10. The system according to claim 9, wherein the control server is further configured to back up data of a control server connected therewith, and to take the place of the failing control server connected therewith.

11. The system according to claim 2, wherein the IP-enabled field device comprises a first IP-enabled field device and/or a second IP-enabled field device, wherein:

the first IP-enabled field device is an intelligent field device supporting the IP protocol; and

the second IP-enabled field device comprises a driver device supporting the IP protocol, and a non-intelligent field device, which does not support the IP protocol, connected with the driver device.
