Description

Technical Field

[0001] The present application relates to the field of highway management, and in particular to an information board information security monitoring system. Background Art

[0002] As the main tool for releasing information on highways, variable information boards provide highway weather information, road construction information, highway blockage information, major highway traffic incidents, highway operation status information, and highway detour plan information through synthetic signals such as text, images, and numbers, so as to help drivers adjust their driving behavior, alleviate traffic congestion, reduce traffic accidents, and improve the traffic capacity of the road network.

[0003] In recent years, the security situation of highway information boards is not optimistic. There are many security risks in the highway information board system itself. Many systems lack sufficient security considerations when designing, and there are loopholes and defects. With the development of information technology and the continuous upgrading of hacker attack technology, the highway information board system faces more and more security threats. Malicious attackers use various attack methods and tools to invade and tamper with the information board system. These attackers are often highly organized and professional, which enables them to quickly spread attacks and cause serious impacts. At the same time, due to human factors and improper operation in the operation and maintenance of the system, it is also easy to cause security incidents.

[0004] At present, the information of the information board is released by the personnel of the monitoring center of each section through the section information board management system. The information board management system is installed in the computer room at the center of the section. Most of the information board equipment is connected to the network of the section through the network port. The information board management system realizes the management function of the equipment through the control protocol of the information board. As long as you are familiar with the control protocol of the information board, you can send instructions to the information board. The reason for this situation is that the information board itself does not support authentication, and there is plain text transmission between the server and the information board, which is equivalent to any control software can send relevant instructions to the information board, which poses a security risk.

[0043] The alarm module is used to issue a first alarm according to the first alarm information.

[0044] In a possible implementation, the information board information security monitoring system further includes: the information board display module includes: an information collection unit and a display unit;

[0045] The information collection unit is connected to the display unit, and is used to collect first display information and send it to the display unit and the information security monitoring module;

[0046] The display unit is used to display the first display information.

[0047] In a possible implementation, the information security monitoring module includes: an image recognition unit and an information comparison unit;

[0048] The image recognition unit is connected to the information comparison unit and the image acquisition module, and is used to recognize the display information in the image on the display interface of the display unit, obtain the second display information and send it to the information comparison unit;

[0049] The information comparison unit is connected to the information comparison unit and the alarm module, and is used to compare the first display information with the second display information, and when the first display information is different from the second display information, send first alarm information to the alarm module.

[0050] In a possible implementation, the information board display module further includes: an information protection unit;

[0051] The information protection unit is connected to the display unit and the information collection unit, and is used to verify and decrypt the first display information, obtain display information recognizable by the display unit, and send the display information to the display unit.

[0052] Optionally, the information protection unit is a VMS gateway.

[0053] Among them, the VMS gateway is a security protection device specially designed for highway information boards. It is mainly responsible for verifying and decrypting externally released information and sending it to the information board for publication and display.

[0054] In a possible implementation, the information board display module further includes: an information board cabinet door status detection unit;

[0055] The information board door state detection unit is connected to the alarm module and is used to send a second alarm message to the alarm module when the information board door is abnormally opened.

Once an abnormal situation is found, corresponding safety measures can be taken immediately; an early warning will be issued when the information board door is opened abnormally, and a magnetic switch will be installed on the door to connect to the IO interface of the VMS gateway; when the door is opened abnormally without plan, the VMS gateway will immediately send an alarm message.

[0057] In a possible implementation, the information board information security monitoring system further includes: an information board power remote control module; the information board power remote control module and the information board display module are used to remotely control the shutdown of the information board display module. The beneficial effect of adopting this implementation is that when an abnormal situation is found, the information board power can be shut down by remote control to quickly cut off the release channel of illegal information, avoid further dissemination of information, and thus reduce potential harm. The release of illegal information often has a certain timeliness. If it is not found in time or handled improperly, it may cause the rapid spread and dissemination of information. By shutting down the information board power by remote control, this situation can be effectively prevented from happening, and the release and dissemination of illegal information may pose a security threat to the information board system itself. By shutting down the power by remote control, further intrusion and damage to the system by illegal information can be avoided, and the safe and stable operation of the system can be protected. The release of illegal information may mislead the public and cause social chaos and panic. By shutting down the information board power in time, the impact of illegal information on society can be reduced, and social stability and public order can be maintained.

[0058] Among them, a new power switch that supports wired protocol (such as 422 protocol, 485 protocol) control is added and connected in series to the power supply line of the intelligence board. Remote security control is achieved through a 422 protocol / TCP protocol converter. Select a suitable 422 or 485 protocol / TCP protocol converter, which can convert 422 / 485 control signals into TCP protocol signals to achieve remote control. The remote platform communicates with the 422 protocol / TCP protocol converter through the internal network and can send control instructions to control the state of the power switch. The remote platform sets appropriate permissions to ensure that only authorized users can send control instructions to ensure security.

[0059] In a possible implementation, the information board display module further includes: a sensitive word recognition unit;

[0060] The sensitive word identification unit is connected to the information protection unit and the information collection unit, and is used to screen the first display information for sensitive words. When the first display information does not contain suspected sensitive words, the first display information is sent to the display module; when the first display information contains suspected sensitive words, a third alarm information is sent to the alarm module.

[0064] The preset display information is the display information pre-stored in the preset display element. With this implementation, when the information board display module is attacked, only the display information pre-stored in the preset display element can be displayed.

[0065] The preset display element stores display information corresponding to the first display information. When the preset display element receives the decrypted first display information, the display information corresponding to the first display information is sent to the display unit for display.

[0066] The information comparison unit compares the display information corresponding to the first display information with the second display information, and when the display information corresponding to the first display information is different from the second display information, sends a first alarm message to the alarm module;
