FIG. 1 is a schematic diagram of the architecture networking of the intelligent parking management system of the present application.
Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The intelligent parking management system provided by the application is characterized in that as shown in fig. 1, the city is divided into a plurality of geographic areas, each area is provided with at least one analysis server, and each analysis server is used for processing and storing parking orders in the area. At least one group of seat groups is arranged in each area, and each seat group at least comprises three seat terminals. The agent group is connected to the agent network through the gateway router, the analysis server can send the order to the agent group through the agent network, the agent personnel of each agent terminal in the agent group can carry out manual verification on the order, and the final verification result is determined according to a few rules obeying most, so that the accuracy of manual verification can be ensured.
Taking the example of parking order generation by capturing a parking image with a camera and then identifying the parking image, identifying the parking image may be performed directly by the camera or sending the image to an analysis server for identification. The recognition result includes parking behavior, license plate number, their corresponding confidence, etc., and then the analysis server forms a parking order for management of charge. The order with high confidence can be directly charged and managed, and the details are not repeated here. The analysis server carries out alarm processing on the low-confidence order and gives the low-confidence order to the seat group for rechecking. The seat personnel can consult the incident and exit photos captured by the camera, the video recorded by the camera or the procedural evidence shot at fixed time through the seat terminal to carry out operations such as modifying license plates, modifying berths, deleting abnormal orders, confirming the departure time from the procedural evidence, and supplementing the entry time from the procedural evidence, thereby completing the verification of the orders. However, the judgment errors may exist only by one seat person, so that a reliable mode is to independently judge and process by a plurality of seat persons, and determine the final verification result according to the principle of minority compliance and majority compliance.
The application provides an intelligent parking management system for agent personnel cooperation, which comprises analysis servers respectively arranged in each geographic area, and at least two agent groups connected with each analysis server through an agent network, wherein the agent network comprises a middle router and a gateway router, each agent group is accessed to the agent network through a corresponding gateway router, each agent group comprises at least three agent terminals, the IP addresses of the agent terminals in the same agent group are in the same network section and are different, and the IP addresses of the agent terminals in different agent groups are the same, wherein:
the analysis server distributes independent serial numbers for each parking order with low confidence coefficient, generates a rechecking task carrying the serial numbers, takes the IP address of the seat terminal as a target address, respectively sends the rechecking task to the seat terminal for rechecking, and receives feedback of the seat terminal to determine a rechecking result of the parking order;
and selecting a routing table item of the shortest path to forward the rechecking task by the intermediate router in the agent network, and if at least two equivalent routing table items exist, locally establishing a control table item comprising a five-tuple, a serial number and an outgoing interface, so that session messages for the same parking order are sent to the same agent terminal.
In this embodiment, as shown in fig. 1, each agent group includes at least three agent terminals, and taking an example that each agent group includes three agent terminals, the three agent terminals may be determined according to a rule of minority compliance and majority compliance when determining the review result finally, and may be set to five. In practical application, setting too many seat personnel can cause personnel waste, and setting three seat terminals for each seat group is preferable.
In the conventional technical solution, in order to send a large number of orders to the agent terminal in an balanced manner, the analysis server may directly configure the destination IP address of the order packet as the IP address of the agent terminal to be sent, or may allocate the agent terminal through a load balancing server. However, these solutions either require manual complex configuration (each interface segment of all gateway routers is not identical, i.e. the whole network does not allow address configuration of the same segment) or require additional equipment or more complex computation. The method automatically realizes approximate equalization of orders among the agent terminals through the characteristics of a routing protocol.
In this embodiment, the IP addresses of the agent terminals in the same agent group are in the same network segment and are different, and the IP addresses of the agent terminals in different agent groups are the same. For example, the three agent terminals in the agent group a are respectively: seat terminal A1:10.10.10.3/24, agent terminal A2:10.10.10.4/24, agent terminal A3:10.10.10.5/24; meanwhile, three seat terminals in the seat group B are respectively: seat terminal B1:10.10.10.3/24, agent terminal B2:10.10.10.4/24, agent terminal B3:10.10.10.5/24.
With this configuration, each gateway router corresponding to the agent group may issue a piece of routing segment information, for example, the routing segment information issued by the gateway router a corresponding to the agent group a is 10.10.10.0/24, and the same routing segment information is issued by the gateway router B as well as 10.10.10.0/24. Since the IP network segments of each agent group are the same, the same routing network segment information of 10.10.10.0/24 is propagated to the whole network through the routing protocol, corresponding routing table entries are generated in each intermediate router according to the routing protocol, and the generation of the routing table entries is a mature technology in the art and will not be repeated here. For the intermediate router, when receiving the routing segment information about 10.10.10.0/24 from the plurality of outgoing interfaces, the intermediate router selects the outgoing interface with the smallest path cost as the outgoing interface of the 10.10.10.0/24 routing table entry according to the principle that the smaller path cost is more important.
For example, two pieces of route segment information of 10.10.10.0/24 have vlan if100 and vlan if200 as outgoing interfaces respectively, and if the route entry path cost of the outgoing interface vlan if100 is minimum, the outgoing interface of the finally effective route entry of 10.10.10.0/24 is vlan fi100.
For a parking order, the analysis server will send it to three agent terminals 10.10.10.3, 10.10.10.4, 10.10.10.5, respectively. Since the IP network segments where the plurality of agent groups are located are the same, these three messages will be sent to the three agent terminals of the 10.10.10.0/24 network segment with the shortest path.
For example, a parking order placed by the analysis server a will be sent to three agent terminals A1, A2 and A3 in the agent group a closest to itself.
According to the embodiment, the IP addresses of the agent terminals in different agent groups are set to be the same, so that the analysis servers can send the parking orders to the agent groups closest to the parking orders, and the review tasks sent by the analysis servers can be sent to the three agent terminals in the closest agent groups respectively only by setting the destination IP to 10.10.10.3, 10.10.10.4 and 10.10.10.5 without complex configuration. In this embodiment, each agent group adopts the same network segment configuration, and issues the same network segment information through the routing protocol, so as to realize the capability of the agent terminal to receive the parking order of the analysis server nearby.
For some intermediate routers in the agent network, there may be multiple agent groups with the same path distance as the intermediate routers, that is, the intermediate routers receive multiple pieces of route segment information about 10.10.10.0/24, and the outgoing interfaces are vlan if10, vlan if11 and vlan if12 respectively, which are called equivalent routes. A complete order session comprises at least the following: the analysis server sends an order review task to the seat terminal 10.10.10.3; after receiving the agreement of the agent terminal 10.10.10.3, the analysis server transmits order information to the agent terminal 10.10.10.3; after receiving the judge result of the agent terminal 10.10.10.3, the analysis server transmits a confirmation message to the agent terminal 10.10.10.3. Because of the existence of the equivalent route, the intermediate router may randomly select one from a plurality of equivalent route table entries for forwarding the message sent by the analysis server a, that is, randomly select one from a plurality of outgoing interfaces of the 10.10.10.0/24 route, which may result in the message of the same order being sent to different actual seat terminals. For example, the order review task is forwarded from the vlan if10, the order information is forwarded from the vlan if11, and the confirmation message is forwarded from the vlan if12, so that confusion is generated, and the session transaction cannot be completed.
In order to deal with the above problem, the source port number of the analysis server may be required to be different for each session, but this way it cannot be guaranteed that the intermediate router must let the messages of the same five-tuple go out from one interface according to the five-tuple, and is subject to the underlying implementation of the router operating system. The embodiment provides a preferred processing mode, the analysis server allocates independent serial numbers for the sessions corresponding to each order, the serial numbers can directly adopt the order numbers of the parking orders, all session signaling messages of the analysis server about the orders need to carry the same serial numbers, and the intermediate router can identify the serial numbers. For an intermediate router with multiple equivalent routes for the destination network segment 10.10.10.0/24, a new control table entry needs to be newly generated whenever a new sequence number is encountered, so that all messages containing the sequence number are forwarded from the same egress interface, i.e., all subsequent messages containing the sequence number match the control table entry and are forwarded from the corresponding egress interface. The control table entry is in the form as follows (assuming all signalling is UDP messages), where the information of the five-tuple is (source IP, source port number, protocol number, destination IP, destination port number) respectively:
TABLE 1
| Sequence number | Five-tuple | Sequence number | Outlet interface |
| 1 | 3.3.3.3/123-UDP-10.10.10.3/456 | 00000000010 | Vlanif10 |
| 2 | 3.3.3.3/123-UDP-10.10.10.3/456 | 00000000011 | Vlanif11 |
| 3 | 3.3.3.3/123-UDP-10.10.10.3/456 | 00000000012 | VlanIf12 |
| 4 | 3.3.3.3/123-UDP-10.10.10.3/456 | 00000000013 | VlanIf10 |
| 5 | 3.3.3.3/123-UDP-10.10.10.3/456 | 00000000014 | Vlanif11 |
For each message with the same five-tuple + sequence number, the intermediate router needs to ensure that the messages are sent out to the matched output interfaces in the control list items, so that the messages about the same order are ensured to be sent to the same seat terminal.
It should be noted that, the agent personnel rechecks the parking order through the agent terminal, gives out the own judgment result, and after feeding back to the analysis server, the analysis server confirms which recheck result is adopted finally according to the feedback of the three agent terminals and the principle of minority compliance, and the details are not repeated here.
In a specific embodiment, the intelligent parking management system for cooperation of seat personnel provided by the application further comprises:
when the intermediate router in the seat network locally establishes the control list items, the quantity of the control list items is uniformly distributed on the output interfaces so as to realize flow balance among the equivalent routing list items.
And deleting the corresponding control list item after the intermediate router in the seat network monitors the end of the session of the parking order.
Specifically, for the packets with the same five-tuple, the conventional processing method of the router forwards the packets from one of the equivalent routes forever, thereby causing traffic imbalance among the equivalent routes. The embodiment gives a preferred implementation, and for the intermediate router with the equivalent route, when the control list items are built locally, the number of the control list items is uniformly distributed on the output interface. As shown in table 1, the number of 5 control entries corresponding to equivalent routes 10.10.10.0/24 is evenly distributed among the three outgoing interfaces, and the number is at most 1 different from each other. Therefore, flow balance among the equivalent routing table items is realized, and load balance is also realized by the corresponding seat group.
After the control list item is established, in order to save the list item space, save the search time and recycle the serial number, when the agent terminal feeds back the rechecking result to the analysis server, the intermediate router detects the message of ending the order session, and then the control list item corresponding to the serial number of the session is deleted.
In another specific embodiment, the intelligent parking management system for seat personnel cooperation provided by the application further comprises:
the gateway router corresponding to each seat group monitors the state of the seat terminal accessed by the gateway router, if the seat terminal is abnormal, the router network segment information corresponding to the seat group is withdrawn, and the host router corresponding to the normal seat terminal is released;
and notifying other gateway routers to withdraw the route network segment information corresponding to the seat group and releasing the host route corresponding to the seat terminal.
Specifically, when an abnormality occurs in an agent terminal in a certain agent group and review processing cannot be performed, the agent group is shielded, or a backup terminal is added in the agent group, however, the former measure causes other normal agent terminals in the whole agent group to stop working, so that resources of the agent group are wasted, orders required to be reviewed by the agent group need to be forwarded to other agent groups, and the workload of other agent groups is increased; the latter measure increases the backup terminals and increases the cost.
For this reason, in the preferred solution of this embodiment, each gateway router maintains the agent terminals in the own agent group, and the gateway router periodically performs signaling interaction with the own agent terminals. For example, the gateway router periodically sends a message to the agent terminal, and the agent terminal needs to reply immediately, and when the gateway router continuously fails to receive information about a certain agent terminal for 3 periods, the agent terminal is considered to be abnormal and loses service capability. For example, the gateway router a is continuously unable to receive the agent terminal A1 in the agent group a: 10.10.10.3/24, the seat terminal is considered abnormal. At this point, gateway router a immediately withdraws routing segment information for the 10.10.10.0/24 segment, issuing 32-bit masked host routes for the other two agent terminals 10.10.10.4 and 10.10.10.5 via the routing protocol.
For example, for an intermediate router, three routing entries for 10.10.10.0/24 are received from the routing protocol, corresponding to the interfaces vlan if100, vlan if200 and vlan if300, respectively, the path from vlan if100 takes the shortest time, the path from vlan if200 takes the longest time, and the routing entry for 10.10.10.0/24 of the interface vlan if100 takes effect according to the routing priority principle when the path is shortest. After the gateway router withdraws the routing entry for the 10.10.10.0/24 segment and issues a 32-bit masked host route for the other two agent terminals 10.10.10.4 and 10.10.10.5 via the routing protocol, the intermediate router will invalidate the 10.10.10.0/24 routing entry with the egress interface vlan if100 and validate the 10.10.10.0/24 routing entry with the egress interface vlan if 200. The host routes 10.10.10.4/32 and 10.10.10.5/32 are validated, and the outgoing interface is vlan if100, which is the same as the original route information of 10.10.10.0/24. Thus, the out-of-service 10.10.10.3 of agent group a will not receive the order, so the intermediate router matches the message with destination IP 10.10.10.3 with the new routing table entry of 10.10.10.0/24, and forwards it from vlan fi200, while both agent terminals 10.10.10.4 and 10.10.10.5 of agent group a can still receive the order. The normal seat terminal of the seat group A can still work, and the resources of the seat group are fully utilized.
It should be noted that, for a router, when forwarding a packet, if the destination address matches both a long-code-mask routing table entry and a short-code-mask routing table entry, the packet is preferentially forwarded according to the long-code-mask routing table entry. For example, a message with destination IP of 10.10.10.3 can be matched with a 10.10.10.3/32 routing table entry or a 10.10.10.0/24 routing table entry, but the mask of the message is longest, and finally the message is forwarded according to the outbound interface of the routing table entry of 10.10.10.3/32. Thus, the above embodiment, according to the best matching rule of the routing table entries, may cause the agent terminals 10.10.10.4 and 10.10.10.5 of the other agent groups to fail to receive the orders, and cause all the orders sent to 10.10.10.4 and 10.10.10.5 to be sent to 10.10.10.4 and 10.10.10.5 of the agent group a.
For the above problem, each gateway router may issue route segment information for each agent terminal IP address by default, but this may make the router have relatively more route information. The application provides a preferred implementation mode, namely when one gateway router withdraws the route network segment information corresponding to the seat group and issues the host route corresponding to the normal seat terminal, other gateway routers are also informed to withdraw the route network segment information corresponding to the seat group and issue the host route corresponding to the seat terminal.
Specifically, when the gateway router a of the present agent group finds 10.10.10.3 out of service, except for immediately withdrawing the network segment routing information about 10.10.10.0/24, other gateway routers are notified to immediately withdraw the network segment routing information about 10.10.10.0/24, and simultaneously issue 32-bit mask routes about the valid agent terminals under the respective names. Gateway router B, having received the notification message, immediately withdraws the segment routing information for 10.10.10.0/24 while simultaneously publishing the 32-bit masked host routes for 10.10.10.3/32, 10.10.10.4/32 and 10.10.10.5/32. Thus, the agent terminals 10.10.10.4 and 10.10.10.5 of the agent groups can still receive orders from the analysis server nearby, and the order equalization processing is realized.
In another specific embodiment, the intelligent parking management system cooperated with the seat personnel further includes:
the gateway router corresponding to each agent group monitors the state of the agent terminal accessed by the gateway router, if the agent terminal is found to be normal, the gateway router also inquires whether the agent terminals accessed by other gateway routers are normal, if the agent terminals accessed by other gateway routers are normal, the router network segment information corresponding to the agent group is released, and the host router corresponding to the agent terminal is withdrawn; and simultaneously notifying other gateway routers to release the route network segment information corresponding to the seat group, and withdrawing the host route corresponding to the seat terminal.
Specifically, when the gateway router a of the agent group finds 10.10.10.3 that service capability is restored, it inquires immediately whether the agent terminals under the names of other gateway routers are normal, and if yes, no subsequent notification is sent. If replies of all other gateway routers are obtained, the agent terminals under the names of the other gateway routers are normal, the agent terminals immediately issue routing information about 10.10.10.0/24, simultaneously withdraw host routes about 10.10.10.4/32 and 10.10.10.5/32, inform the other gateway routers to immediately issue the routing information about 10.10.10.0/24, and simultaneously withdraw 32-bit mask host routes about the agent terminals with service capability, thereby saving routing table items of each gateway router.
According to the embodiment, through interaction among the gateway routers, when the agent terminals in one agent group are abnormal, the cooperation processing of tasks is completed through cooperation with other agent groups.
In a specific embodiment, considering the situation that feedback results of three agent terminals in an agent group are inconsistent, the analysis server evaluates the correct rechecking result according to the principle of minority compliance. The traditional technical scheme does not have a good correction means for the condition of inconsistent feedback results, and cannot feed back the rechecking errors. Therefore, the intelligent parking management system for the cooperation of the seat personnel, provided by the application, further comprises:
the analysis server determines a rechecking result according to a minority compliance majority rule;
after determining the rechecking result according to a few rules of majority compliance, the analysis server sends an alarm message carrying the rechecking result to the seat terminal with different feedback and rechecking results.
Specifically, for example, for checking a parking order, after the analysis server a receives feedback of each agent terminal in the agent group a, it finds that feedback results of the agent terminal A1 and the agent terminal A2 are the same, and feedback results of the agent terminal A3 are different, and at this time, the determined checking result is the feedback result of the agent terminal A1 and the agent terminal A2.
After the analysis server A finds that the result appears, an alarm message is sent to the seat terminal A3, and the alarm message carries a rechecking result. After the agent terminal A3 receives the information, it pops up or records the alarm information, the agent personnel can review the relevant materials again according to the review result to find out the reason of the error of the judgment, or after carefully confirming or persisting the original judgment, it can request the system to put the parking order into the catalogue which needs to be processed in particular, and review together with other agent personnel to give the final review result.
Through the technical scheme of the embodiment, the condition of rechecking errors can be further reduced, meanwhile, the method has the effect of rechecking skill training on the seat personnel, and the probability of rechecking errors again for the seat personnel is reduced.
It should be noted that, in order to ensure that the analysis server can accurately send the alarm message to the checking agent terminal, the intermediate router may keep the control table entry for a period of time, or delete the control table entry after hearing the alarm message, which will not be described herein.
In another embodiment of the present application, there is further provided an intelligent parking management method for agent cooperation, in analysis servers of each geographical area, each analysis server is connected to at least two agent groups through an agent network, the agent network includes an intermediate router and a gateway router, each agent group is connected to the agent network through a corresponding gateway router, and the intelligent parking management method for agent cooperation includes:
each agent group comprises at least three agent terminals, the IP addresses of the agent terminals in the same agent group are in the same network segment and are different, and the IP addresses of the agent terminals in different agent groups are the same, wherein:
the analysis server distributes independent serial numbers for each parking order with low confidence coefficient, generates a rechecking task carrying the serial numbers, takes the IP address of the seat terminal as a target address, respectively sends the rechecking task to the seat terminal for rechecking, and receives feedback of the seat terminal to determine a rechecking result of the parking order;
and selecting a routing table item of the shortest path to forward the rechecking task by the intermediate router in the agent network, and if at least two equivalent routing table items exist, locally establishing a control table item comprising a five-tuple, a serial number and an outgoing interface, so that session messages for the same parking order are sent to the same agent terminal.
The above examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the application. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
