The traffic signal machine is widely used in China, but with the rapid development of traffic and network security technologies, the traffic signal machine cannot adapt to the requirements of traffic security in new situations, and malicious persons can destroy or illegally control the traffic signal machine in a remote or physical contact mode, for example, the traffic signal machine cannot give an alarm even if the traffic signal of the whole city is changed into green by using a conflict table of the traffic signal machine, so that each traffic intersection generates a serious traffic accident, and the city operation falls into paralysis.
At present, there is no technical scheme in the prior art that can monitor the collision table of the traffic signal, and the safety monitoring of the collision table of the traffic signal is still in a blank stage.
Based on this, the embodiment of the disclosure provides a method for monitoring tampering of a conflict table of a traffic signal machine, which solves the problem that in the prior art, a conflict table in a traffic signal machine is tampered and cannot be monitored by related workers, so that a major traffic accident occurs.
The collision table tampering monitoring method of the traffic signal machine according to the embodiment of the present disclosure is described in detail below with reference to the drawings.
Fig. 1 is an architecture diagram of a traffic control system according to an exemplary embodiment of the present disclosure, and as shown in fig. 1, the system may include a workstation 11, a zone server 12, a monitoring device 13, a core switch 14, a serial server 15, an optical terminal 16, and a traffic signal 17, where the workstation 11, the zone server 12, the core switch 14, the serial server 15, the optical terminal 16, and the traffic signal 17 are components of an existing traffic control system.
In the embodiment of the present disclosure, the monitoring device 13 is added on the basis of the existing traffic control system, as shown in fig. 1, the monitoring device 13 is accessed to the existing traffic control system regional core switch in a bypass deployment manner, and performs data interaction with the traffic signal machine 17 in a serial communication manner through the serial server 15.
The hardware platform of the monitoring device 13 is a general-purpose server, that is, a server, or a personal PC, a notebook, or the like, but the server is mainly used.
The traffic signal machine 17 body mainly comprises a control box, a power distribution unit and a cabinet.
The control box mainly comprises a 6U rack, and the 6U rack comprises a control board, a phase driving board and a vehicle detector which are connected through a bus.
The power distribution unit comprises a switch, a fuse, a distribution board, a power supply, leakage protection, a lightning protection module and the like.
Devices working in the open air need to have the characteristics of water resistance, pressure resistance and shock resistance, and therefore, the cabinets are mostly made of aluminum alloy. The traffic signal machine can be ensured to operate stably and work continuously for a long time.
It is to be noted that the above description about the structure of the traffic signal is merely illustrative, and in other examples, the traffic signal may have other structures.
The traffic control system shown in fig. 1 is also merely an example of a system to which the monitoring device 13 can be applied, and in many cases, the monitoring device can be applied to a system of other structure as long as it is satisfied that the system can communicate with the traffic signal 17.
Fig. 2 is a flowchart of a collision table tampering monitoring method for a traffic signal according to an exemplary embodiment of the present disclosure. The method may be performed by a monitoring device. As shown in fig. 2, the exemplary embodiment method may include the following processes:
step S201, data information of the traffic signal is acquired.
The data information is stored in a designated memory and a disk area of the traffic signal.
The data information includes a correspondence between each lamp group and an input/output interface of the traffic signal, a correspondence between each lamp group and an intersection, a correspondence between each lamp group and a direction, a time when each lamp group is in red light, green light, yellow flashing, and conflict table information corresponding to the traffic signal.
The lamp groups in four directions of one crossroad are controlled by one traffic signal machine, so that different lamp groups need to correspond to different input and output interfaces of the traffic signal machine, and different lamp groups are conveniently and respectively operated subsequently. Further, since the light groups in four directions at a plurality of intersections can be controlled by one traffic signal, the data information of the traffic signal should include the correspondence between the light groups and the intersections and between the light groups and the directions.
For a group of lights, the time of red, green and yellow flashing can be set by the relevant staff, for example, the time of red light of the traffic lights in the north and south directions of an intersection is 60S, then the time of green light is 30S, and the time of yellow flashing is 20S.
In an alternative example, the data information of the traffic signal may be actively transmitted to the monitoring device by the traffic signal at preset time intervals.
In an optional example, the monitoring device may send a data request instruction to the traffic signal at preset time intervals, and the traffic signal sends the data information to the monitoring device based on the data request instruction after receiving the data request instruction. The time interval may be set manually on the monitoring device by the relevant staff.
In an alternative example, the traffic signal may be a signal supporting communication using ethernet, and since the monitoring device may support communication using ethernet, communication between the monitoring device and the traffic signal may not pass through the serial server. The monitoring device can send a data request instruction to the traffic signal machine through the Ethernet, and after the traffic signal machine receives the data request instruction, the traffic signal machine sends the data information to the monitoring device through the Ethernet based on the data request instruction.
In an alternative example, the traffic signal may be a signal that does not support communication using ethernet, and in this case, the traffic signal and the monitoring device need to communicate through the serial server.
Specifically, as shown in fig. 1, the monitoring device is connected to the serial server through an ethernet, the traffic signal machine is directly connected to the serial server, then the monitoring device may send a data request instruction to the traffic signal machine through a serial communication manner to obtain data information of the traffic signal machine, and after the traffic signal machine obtains the data request instruction, the data information is fed back to the monitoring device based on the data request instruction.
In this example, the monitoring device can actively communicate with the traffic signal machine in a serial communication mode by using a serial protocol, so that the problem of communication protocol compatibility is solved.
Step S202, analyzing the data information of the traffic signal machine to obtain the current conflict list used by the traffic signal machine.
The current conflict table comprises lamp group conflict information of the traffic signal machine, the lamp group conflict information exists in the conflict table in a two-dimensional array mode, and IDs of two lamp groups which may conflict are stored in each two-dimensional array.
For example, the IDs of two possibly conflicting lamp groups stored in the two-dimensional array may be 1 and 2, respectively. As another example, the IDs of two possibly conflicting lamp groups stored in the two-dimensional array may be 4 and 5, respectively. This example is not intended to be limiting.
The conflict list is a configuration file in the traffic signal machine, and the staff can configure the lamp group conflict information of the traffic signal machine in the conflict list. When the traffic signal machine has a fault or the information of the traffic intersection lamp group conflicts due to manual operation, for example, the traffic light in the east-west direction and the traffic light in the south-north direction of one intersection are simultaneously changed into green, namely, the situation of controlling one lamp group recorded in the conflict list of the traffic signal machine at the intersection occurs, the traffic signal machine gives out fault alarm, and simultaneously, the traffic lights at the intersection are all switched into a yellow flashing state, so that the occurrence of serious traffic accidents caused by the information conflict of the lamp groups is avoided.
In an alternative example, the monitoring device may parse the data information of the traffic signal to obtain a current profile of the traffic signal. The current configuration file may include information such as a plurality of address pointers, the current conflict table, and the length of the current conflict table. A pointer pointing to an address storing the current conflict table may be referred to as a first address pointer, a pointer pointing to an address storing a length of the current conflict table may be referred to as a second address pointer, and a pointer pointing to an address storing the second address pointer may be referred to as a third address pointer, where storage addresses of the first address pointer and the third address pointer are fixed and known.
Further, the monitoring device may read the storage address of the current conflict table from the first address pointer. And reading the storage address of the second address pointer from the third address pointer, and reading the length of the current conflict list from the second address pointer. And then, extracting the current conflict table used by the traffic signal machine from the current configuration file according to the read storage address and length of the current conflict table.
In this example, the monitoring device may automatically extract the current conflict table from the current configuration file of the traffic signal machine, so as to facilitate a subsequent operation of comparing the current conflict table with the original conflict table. And because the traffic signal machine is only compared and monitored by the key part of the conflict table, the comparison range is reduced, and the comparison speed and efficiency are improved.
Step S203, comparing the current conflict table with a pre-configured original conflict table.
In an alternative example, the monitoring device may receive a user-uploaded original profile of the traffic signal before acquiring the data information of the traffic signal, and use the original profile as a baseline.
In an alternative example, the original profile of the traffic signal may be uploaded by a user.
In computer terminology, the baseline is a "snapshot" of each artifact version in the project repository over a particular period of time. It may provide a formal standard upon which subsequent work is based and which can only be altered after authorization. After an initial baseline is established, each subsequent change to it will be recorded as a difference until the next baseline is established. In this embodiment, the original configuration file is used as a baseline, that is, the original configuration file is used as a reference for subsequent comparison.
The original configuration file may contain a plurality of address pointers, an original conflict table, and a length of the original conflict table. A pointer to an address storing the original conflict table may be referred to as a fourth address pointer, a pointer to an address storing the length of the original conflict table may be referred to as a fifth address pointer, a pointer to an address storing the fifth address pointer may be referred to as a sixth address pointer, and storage addresses of the fourth address pointer and the sixth address pointer are fixed and known.
Further, the monitoring device may read the storage address of the original conflict table from the fourth address pointer. And reading the storage address of the fifth address pointer from the sixth address pointer, and reading the length of the original conflict table from the fifth address pointer. And then, extracting the original conflict table from the original configuration file according to the storage address and the length of the original conflict table. The original collision table also includes information on the collision of the traffic signal light groups.
And then comparing the lamp group conflict information stored in the current conflict table with the lamp group conflict information stored in the original conflict table.
And step S204, responding to the situation that the data stored in the current conflict table and the data stored in the original conflict table are not identical, and performing conflict table tampering alarm.
The tampering of the conflict table refers to an action that malicious personnel uses a special tool to modify the content of the conflict table through a network or physical contact mode and the like, so that the traffic signal conflict detection function of the traffic signal machine is disabled.
The data stored in the current conflict table and the data stored in the original conflict table are lamp group conflict information stored in the current conflict table and the original conflict table, and when the lamp group conflict information stored in the current conflict table and the lamp group conflict information stored in the original conflict table are not identical, it is indicated that someone tampers with the conflict table of the traffic signal machine, so that the monitoring device immediately sends a warning of tampering of the conflict table.
For example, the lamp group information in the original conflict table is 1, 2 and 3, 4, and the lamp group information in the current conflict table is 1, 3 and 3, 4, that is, the original conflict table is not identical to the lamp group information stored in the current conflict table, and the monitoring device issues the conflict table tampering warning.
In an optional example, the monitoring device may issue an alarm through a prompt box for popping up the collision table tampering on an interface of the monitoring device, and may also issue an alarm through an audio prompt. This example is not particularly limited.
In an alternative example, the lamp group conflict information stored in the current conflict table and the original conflict table may be identical. At this time, it is indicated that no one has tampered with the original collision table, and therefore, the monitoring device may obtain the data information of the traffic signal again after a preset time interval, further analyze the data information of the traffic signal, obtain the current collision table used by the traffic signal, and compare the current collision table with the original collision table serving as the baseline. And if the data stored in the current conflict table and the data stored in the original conflict table are not identical, carrying out conflict table tampering warning, and otherwise, circularly executing the process.
According to the method for monitoring tampering of the conflict table of the traffic signal, the current conflict table is extracted from the current configuration file of the traffic signal through the monitoring device, the state of the conflict table of the traffic signal is effectively monitored through the method for comparing the current conflict table with the original conflict table, and the problem that in the prior art, the conflict table in the traffic signal is tampered, and related workers cannot monitor the conflict table, so that major traffic accidents occur is solved.
Fig. 3 is a flowchart of a collision table tampering monitoring method for a traffic signal according to an exemplary embodiment of the disclosure. In the description of the present embodiment, the same steps as those in any of the foregoing embodiments will be briefly described, and detailed descriptions thereof will be omitted, so that reference may be made to any of the foregoing embodiments. As shown in fig. 3, the embodiment method may include the following processes:
step S301, acquiring an original configuration file of the traffic signal, and extracting to obtain an original conflict table of the traffic signal according to the storage address and the length of the conflict table in the original configuration file.
Step S302, acquiring the data information of the traffic signal machine.
Step S303, analyzing the data information of the traffic signal to obtain the current configuration file of the traffic signal.
In an alternative example, a data-instruction mapping table may be previously constructed, where the data-instruction mapping table includes two parts, namely data and an instruction corresponding to the data, and the instruction is used to control a lamp group state of the traffic signal or to indicate that the traffic signal needs to be processed.
For example, in the data-instruction mapping table, the data may be 0F0F, and the instruction corresponding to the data may be a DFY instruction, meaning closed.
In an alternative example, the DFY command can be used to turn off the red light of the light group.
In another alternative example, the DFY instructions may be used to turn off green lights of the light group.
For another example, the data may be 4EFF and the instruction corresponding to the data may be an RMC instruction, meaning that a parity value is read.
The RMC command may be used to instruct the traffic signal to check whether the data transmitted by the remote host through the serial server or the ethernet is faulty during the transmission process. It should be noted that the description of the data and the instructions corresponding to the data are merely illustrative, and are only for better understanding of the structure of the data-instruction mapping table. For traffic signals produced by different manufacturers, the data in the data-instruction mapping table and the instructions corresponding to the data are different, and specific analysis is required according to specific conditions.
In an optional example, a file may be created in the memory of the monitoring device, and the acquired data information of the traffic signal may be sequentially stored in the file according to the acquisition order. Then, data with fixed length is extracted from the file, and the specific value of the fixed length is determined by the value of the fixed length of the instruction in the instruction set adopted by the traffic signal machine. And each piece of the fixed length data can carry a data label, and the data label is used for indicating whether an instruction corresponding to the fixed length data exists in the pre-constructed data-instruction mapping table or not.
When the extracted data label carried by the data with the fixed length indicates that the instruction corresponding to the data with the fixed length exists in the pre-constructed data-instruction mapping table, searching the corresponding instruction in the pre-constructed data-instruction mapping table according to the data with the fixed length, and writing the instruction into the current configuration file.
When the extracted data label carried by the fixed length data indicates that no instruction corresponding to the fixed length data exists in the pre-constructed data-instruction mapping table, writing the extracted fixed length data into the current configuration file.
For example, when the extracted data is 0F0F, the label carried by the extracted data indicates that there is an instruction corresponding to the data in the pre-constructed data-instruction mapping table, and when the extracted data is 1 or 2, the label carried by the extracted data indicates that there is no instruction corresponding to the data in the pre-constructed data-instruction mapping table.
In this example, the data information acquired from the traffic signal machine can be automatically restored to the current configuration file of the traffic signal machine through the monitoring device, so as to facilitate the subsequent operation of extracting the current conflict list.
And step S304, extracting and obtaining the current conflict table used by the traffic signal according to the storage address and the length of the conflict table in the current configuration file.
Step S305, comparing the current conflict table with the original conflict table, and determining whether the data stored in the current conflict table and the data stored in the original conflict table are completely the same.
If the data stored in the current conflict table is identical to the data stored in the original conflict table, after a preset time interval, step S302 is executed.
If the data stored in the current conflict table and the data stored in the original conflict table are not identical, step S306 is continuously executed.
And step S306, sending a conflict table tampering alarm.
And the conflict table tampering alarm is used for prompting relevant staff that the conflict table of the traffic signal machine has been tampered.
At this point, when the monitoring process is finished, the monitoring device may submit the part of the traffic signal machine where the difference exists between the current conflict table and the original conflict table to a relevant worker for confirmation, and after the confirmation, the monitoring device may return to step S302 to restart the monitoring process.
According to the method for comparing the current conflict table with the original conflict table, the state of the conflict table of the traffic signal machine can be effectively monitored, and when illegal personnel falsify the conflict table is monitored, a conflict table tampering alarm can be rapidly sent out, so that relevant workers are reminded to timely find and block a tampered path and tampering behaviors, major traffic accidents are prevented, and the safety of lives and properties of people is guaranteed.
