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 plurality of control servers, each of the plurality of control servers arranged at a separate intersection;

a plurality of IP-enabled field devices configured to communicate with the plurality of control servers over an IP address based broadband bus; and

a central system configured to exchange data with the plurality of control servers over a network;

wherein;

the central system is configured to;

receive status data of the plurality of control servers in real time, receive statistic and inquired data from the plurality of control servers in a non-real time manner, and subscribe to stored data of the plurality of control servers when needed;

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

each of the plurality of the control servers is configured to control traffic in a local area by;

analyzing and storing the data collected by one or more IP-enabled field devices communicating with the control server, generating one or more control instructions for the one or more IP-enabled field devices, and transmitting the one or more control instructions to the one or more IP-enabled field devices so that the one or more IP-enabled field devices perform one or more operations according to the one or more control instructions, and when determining that a preset trigger condition is satisfied;

determine a pre-determined customized area comprising the control server, and negotiate with one or more other control servers in the pre-determined customized area to determine a master control server in the pre-determined customized area, or, contend for becoming the master control server among all control servers in the pre-determined customized area;

wherein;

any control server in the pre-determined customized area which is not the master control server is a slave control server in the pre-determined customized area;

determining that the preset trigger condition is satisfied, comprises;

when determining that an amount of data to be processed is greater than a preset data amount, determining that the preset trigger condition is satisfied;

or, when determining that a traffic jam occurs in the pre-determined customized area, determining that the preset trigger condition is satisfied;

or, when determining that information about an object in the pre-determined customized area needs to be inquired about, determining that the preset trigger condition is satisfied;

the pre-determined customized area comprises;

a customized area determined by an operator before the control server analyzes and stores the data collected by the one or more IP-enabled field devices;

a customized area automatically determined when the control server analyzes and stores the data collected by the one or more IP-enabled field devices according to needs;

or, a customized area determined when the control server receives a request to determine the customized area and requests one or more adjacent control servers proximate thereto to determine the customized area; and

if the control server is the master control server in the pre-determined customized area, then the control server is further configured to generate a coordinated control strategy through self-learning and edge computing to perform coordinated control in the customized area by sharing data of one or more slave control servers, analyzing and processing the shared data;

or if the control server is the slave control server, then the control server is further configured to acquire a coordinated control strategy from the master control server through cloud computing.

2. The system according to claim 1, wherein for each traffic direction at an intersection, one of the plurality of control servers at the intersection communicates with the one or more IP-enabled field devices in the traffic direction over one IP address based broadband bus in the traffic direction;

or

one of the plurality of control servers at an intersection communicates with one or more IP-enabled field devices in all directions at the intersection over one common IP address based broadband bus.

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

and

the coordinated control strategy is configured for;

traffic regulation enforcement, locus tracking, traffic control, and locating of an object to be located.

4. The system according to claim 3, wherein the central system is further configured to:

share data stored in the plurality of control servers, analyze and process the shared data to obtain a result of the analysis;

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

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

5. The system according to claim 1, wherein the customized area comprises the local area of the control server, and one or more local areas of one or more specified control servers different from the control server;

and

the control servers in the customized area store data in a distributed manner.

6. The system according to claim 1, wherein the plurality of IP-enabled field devices comprise 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; and

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

7. The system according to claim 6, wherein each of the plurality of control servers is further configured to:

allocate a unique IP address for each IP-enabled field device communicating the control server.

8. The system according to claim 3, wherein each of the plurality of control servers is further configured to back up data of a control server connected therewith, and take the place of a failing control server connected therewith.

9. The system according to claim 2, wherein each of the plurality of IP-enabled field devices comprises a first IP-enabled field device and/or a second IP-enabled field device, wherein:
