Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunnel equipment management, and particularly relates to a tunnel safety operation and maintenance management system. BACKGROUND

[0002] Tunnel construction is one of the important national infrastructure, and tunnel engineering is a lifeline project related to the coordinated development of society and economy. The rapid development of tunnel construction, huge capital investment and prominent role in the economic society make people pay more and more attention to the safety and durability of the tunnel. The equipment in the tunnel, such as lighting equipment and ventilation equipment, has great significance for the safety of the tunnel, and generally needs to be detected regularly to collect information for timely maintenance.

[0003] The traditional equipment maintenance in the tunnel is usually recorded by the on-site personnel, and the detection report is written after returning to the residence. The traditional operation method is prone to recording errors and occupies a large amount of personnel working hours, resulting in low detection efficiency.

[0004] In order to solve the above problems, the existing tunnel equipment detection system detects the running state of the equipment in the tunnel in real time through detection equipment such as sensors or cameras, and sends the corresponding data to the remote monitoring personnel when detecting the abnormality, so as to realize the detection and maintenance of the equipment in the tunnel. However, the disadvantage of this method is high maintenance cost and poor compatibility. Whenever a new device is added in the tunnel, the selection of the detection device needs to be targeted for the device, and the detection requirements of each device for the detection device are different, which will obviously increase the complexity of the later maintenance. SUMMARY

[0005] One of the purposes of the present application is to provide a tunnel safety operation and maintenance management system, which can solve the problems of high cost and complex operation and maintenance in the prior art.

[0006] In order to achieve the above purpose, a tunnel safety operation and maintenance management system is provided, which comprises a client arranged in the tunnel and a server.

[0007] The client is used for communicating with the vehicle-mounted event data recorder after sending a communication connection message to the vehicle-mounted event data recorder in the tunnel.

[0008] The client is also used for obtaining the tunnel record information recorded by the vehicle-mounted event data recorder and sending the tunnel record information to the server after communicating with the vehicle-mounted event data recorder.

[0009] The server is used for identifying the running state of the equipment in the tunnel according to the tunnel record information, and sending a maintenance signal to the remote monitoring personnel if the equipment in the tunnel is identified to have a fault.

[0010] The technical principle and effect of the scheme: in the scheme, the client is arranged in the tunnel, and then the client is used to send a communication connection message to the vehicle passing through the tunnel, at this time the vehicle's driving recorder will receive the communication connection message, so that the communication connection between the client and the driving recorder of the vehicle passing through the tunnel is realized, so that the tunnel record information recorded by the driving recorder in the tunnel is acquired, and then the server is used to identify the running state of the equipment, so that the running state of the equipment in the tunnel is monitored through this way.

[0011] Compared with the existing way of monitoring the equipment in the tunnel by arranging a camera in the tunnel, the scheme realizes the sampling of the running state of the equipment in the tunnel through the communication connection between the client and the driving recorder of the vehicle in the tunnel, which greatly reduces the cost of monitoring the running state of the equipment in the tunnel. That is, the scheme fully considers that most of the vehicles passing through the tunnel are equipped with driving recorders to ensure the driving safety record, so that the vehicles passing through the tunnel actually collect the specific conditions in the tunnel, and the tunnel record information recorded by the driving recorder can clearly understand the situation in the tunnel. At the same time, considering that the access to the data in the driving recorder only needs to establish a communication connection, at this time, the communication connection between the client and the driving recorder of the vehicle in the tunnel can realize the collection of the equipment in the tunnel. By establishing a communication connection with the driving recorders of multiple vehicles, the running state of the equipment in the tunnel is collected multiple times, which not only improves the diversity of the collection of the running state of the equipment in the tunnel and the accuracy of the judgment of the running state of the equipment, but also greatly saves the corresponding cost.

[0012] At the same time, when the driving recorder is updated or changed, only the specific communication connection message needs to be realized at the client level, that is, the client needs to be updated, and since the client does not have a complex video shooting function, but only acquires the tunnel record information recorded by the driving recorder of the vehicle in the tunnel, the update of the client is relatively simple, the corresponding cost of upgrading is low, the subsequent maintenance and change process of the system is simplified, the cost of subsequent maintenance of the system is greatly reduced, and the universality of the system is improved.

[0013] Further, the client acquires the basic information of the driving recorder of the vehicle in the tunnel before sending the communication connection message to the driving recorder of the vehicle in the tunnel.

[0014] The client identifies the type of the driving recorder corresponding to the basic information of the driving recorder according to the basic information of the driving recorder, matches the type of the client corresponding to the driving recorder based on the type of the driving recorder, and sends a communication connection message to the driving recorder according to the matched type of the client.

[0015] Beneficial effects: In this scheme, it is fully considered that the models of the driving recorders corresponding to different vehicles may be different, so it is necessary to select the client that can match the model of the corresponding driving recorder when sending the communication connection message, so as to realize the sending function of the communication connection message.

[0016] Further, the communication connection message encapsulates a communication connection password applicable to the driving recorder; the communication connection password is associated with the license plate information of the vehicle where the driving recorder is located and is stored in the memory space.

[0017] After identifying the corresponding type of the client, the client acquires the license plate information corresponding to the vehicle, judges whether the corresponding license plate information is stored in the memory space based on the acquired license plate information, and if so, acquires the communication connection password managed by the license plate information.

[0018] The client receives and analyzes the communication connection message in the driving recorder, and acquires the communication connection password from the communication connection message, and then performs communication connection with the driving recorder.

[0019] Beneficial effects: In this scheme, the security and reliability of the communication connection between the client and the driving recorder are realized through the setting of the communication connection password.

[0020] Further, the communication connection message includes a signal connection strategy, and the client judges whether each driving recorder establishes communication connection with the client according to the signal connection strategy when sending the communication connection message to the driving recorder on the vehicle in the tunnel, and performs corresponding communication connection according to the judgment result.

[0021] Beneficial effects: The driving recorder that establishes communication connection with the client is selected through the setting of the signal connection strategy.

[0022] Further, the signal connection strategy is:

[0023] The driving speed of the vehicle in the tunnel is acquired, and the size of the driving speed and the preset speed is judged, when the driving speed is less than or equal to the preset speed, it is judged that the tunnel where the vehicle is located may have a problem, and the tunnel condition at this position needs to be checked; otherwise, it is judged that the vehicle is driving normally in the tunnel.

[0024] In a case where it is determined that the tunnel at the position of the vehicle may have a problem, the tunnel at the position is needed to be viewed, the position of the vehicle is needed to be located, vehicle position information corresponding to the position of the vehicle is generated, a connection priority corresponding to the vehicle position information is determined based on the vehicle position information, and a connection matching probability of the vehicle corresponding to the connection priority is generated according to the determined connection priority.

[0025] Beneficial effects: In the scheme, the driving recorders for establishing a communication connection are selected by determining the driving speed and the connection matching probability, and the connection priority of the driving recorder closest to the position of the client is higher, and the corresponding connection matching probability is greater, so that the stability of the communication connection is stronger, and the randomness of the connection is stronger.

[0026] Further, the server is further configured to generate a client arrangement strategy based on a tunnel according to tunnel basic information and tunnel vehicle driving condition information; the tunnel basic information includes a tunnel length, a humidity change condition where the tunnel is located, and a tunnel equipment failure rate; and the tunnel vehicle driving condition information includes a historical tunnel vehicle average speed, a tunnel accident occurrence probability, and an accident common occurrence point.

[0027] Beneficial effects: In the scheme, the arrangement of the client is set according to the basic information of the tunnel where the client is located and the vehicle driving condition information in the tunnel, so that the setting of the client is more targeted, and the feasibility and rationality of the set position are greatly improved.

[0034] Embodiment one

[0035] A tunnel safety operation and maintenance management system, substantially as shown in Figure 1 includes a client and a server arranged in the tunnel;

[0036] The client is used to communicate with the vehicle-mounted DVR in the tunnel after sending a communication connection message to the vehicle-mounted DVR. In this embodiment, the communication connection between the client and the vehicle-mounted DVR is achieved through the connection between the WiFi modules of the client and the vehicle-mounted DVR. In this embodiment, multiple clients are arranged in the tunnel, which can be uniformly distributed in the tunnel or arranged according to the vehicle speed in the tunnel, for example, one client is arranged per meter in the area where the vehicle speed is low, and one client is arranged per 10 meters in the area where the vehicle speed is high.

[0037] Before the client sends a communication connection message to the vehicle-mounted DVR in the tunnel, the basic information of the vehicle-mounted DVR is acquired.

[0038] The client identifies the type of the driving recorder corresponding to the basic information of the driving recorder according to the basic information of the driving recorder, matches the type of the client corresponding to the driving recorder based on the type of the driving recorder, and calls the client corresponding to the matched type of the client to send a communication connection message to the driving recorder based on the matched type of the client. In this embodiment, considering that the models and types of the driving recorders on vehicles in the tunnel are different, the selection of the client is needed when the communication connection message is sent, so as to realize the matching of the driving recorders. Specifically, the basic information of the driving recorder on the vehicle is acquired, and the basic information includes the WiFi name of the driving recorder. After the WiFi on the driving recorder is turned on, the WiFi name is generally not changed by the user, and the WiFi name on the driving recorder basically reflects the model thereof. For example, the WiFi name is CZL85bf, and it can be known that the type of the driving recorder corresponding to the WiFi name is CZL recorder.

[0039] Therefore, the client also searches other WiFi within the range involved by the client through the WiFi mode, determines the model of the driving recorder through the searched WiFi name, selects the type of the client according to the model of the driving recorder, and calls the client of the corresponding type of the client.

[0040] The communication connection message encapsulates a communication connection password suitable for the driving recorder; the communication connection password is associated with the license plate information of the vehicle where the driving recorder is located and is stored in the memory space.

[0041] After the corresponding type of the client is identified, the client acquires the license plate information corresponding to the vehicle, judges whether the corresponding license plate information is stored in the memory space based on the acquired license plate information, and calls the communication connection password managed by the license plate information if the corresponding license plate information exists.

[0042] In this embodiment, the user uses the system to authorize the license plate information, the communication connection password, and the basic information of the driving recorder, so as to realize the storage of the basic information of the vehicle of all users, that is, the license plate information, the communication connection password, and the basic information of the driving recorder of all users are stored in the first database, and all data of the same user are associated and set.

[0043] In order to realize the recognition of the license plate information of the vehicle entering the tunnel, so as to realize the acquisition of the communication connection password associated with the license plate information, and then enable the client in the tunnel to match the license plate information and the communication connection password of the vehicle corresponding to the tachograph when the basic information of the tachograph is recognized, the present embodiment also proposes a password recognition method based on the tachograph of the vehicle in the tunnel, comprising the following steps:

[0044] A corresponding camera is arranged at the entrance of the tunnel, and the image of the vehicle entering the tunnel is photographed by the camera at the entrance of the tunnel;

[0045] The license plate information of the corresponding vehicle is recognized based on the image, and based on the license plate information, the basic information and the communication connection password of the tachograph associated with the license plate information are retrieved from the first database and stored in the second database;

[0046] Subsequently, after the vehicle enters the corresponding tunnel, when the corresponding client acquires the basic information of the tachograph on the vehicle, the license plate information and the communication connection password associated with the basic information of the tachograph are directly obtained from the second database based on the acquired basic information of the tachograph, and then subsequent communication connection is performed.

[0047] Of course, in order to enable the second database to be used better, a camera is also arranged at the exit of the tunnel to determine the vehicle leaving the tunnel by the camera at the exit of the tunnel, and after the license plate information of the vehicle is collected by the camera, the license plate information in the second database, and the basic information and the communication connection password of the tachograph associated with the license plate information are deleted, thereby realizing the reasonable use of the storage space in the second database.

[0048] By arranging a camera at the entrance of the tunnel, the data of the vehicle entering the tunnel is collected, and the first high accuracy and high reliability of the data collection of the vehicle entering the tunnel is realized, so that the client can quickly acquire the communication connection password and the license plate information when establishing communication connection with the tachograph on the vehicle, greatly improving the speed of establishing communication connection between the client and the tachograph.

[0049] By using the tunnel recording information on the tachograph, the whole process of the tunnel can be recorded, and the whole recording is dynamic, compared with simply arranging some cameras to monitor the equipment in the tunnel, the present scheme realizes the whole process recording of the tunnel, and the probability of dead angle of recording is lower.

[0050] The client receives and parses the communication connection packet in the driving recorder, and after obtaining the communication connection password from the communication connection packet, the client performs communication connection with the driving recorder. In this embodiment, it is first considered that the WiFi on the driving recorder generally needs a corresponding password to be connected, so the corresponding communication connection password is encapsulated when the communication connection packet is sent to the driving recorder, so that only when the communication connection password is matched, the communication connection is performed. Of course, there is also a part without communication connection password, so direct connection can be performed.

[0051] The communication connection packet includes a signal connection strategy. When the client sends the communication connection packet to the driving recorder on the vehicle in the tunnel, the signal connection strategy is used to determine whether each driving recorder establishes communication connection with the client, and the corresponding communication connection is performed according to the determination result.

[0052] The signal connection strategy is:

[0053] The driving speed of the vehicle in the tunnel is obtained, and the driving speed and the preset speed are compared to determine whether the vehicle in the tunnel is driving normally.

[0054] When it is determined that the tunnel at the position of the vehicle may have a problem and the tunnel condition at this position needs to be checked, the position of the vehicle is located, the corresponding vehicle position information is generated, the corresponding connection priority is determined based on the vehicle position information, and the connection matching probability of the vehicle corresponding to the connection priority is generated according to the determined connection priority.

[0055] In this embodiment, not every driving recorder on the vehicle passing through the client can perform communication connection with the client, and there is still a certain signal connection strategy.

[0056] Specifically, when the client sends the communication connection packet, the driving speed of the vehicle in the range of the client sending is first obtained, and the driving speed and the preset speed are compared to determine whether the vehicle in the tunnel is driving abnormally, for example, the lighting system on the side is damaged, so the driver slows down to pass this section of road smoothly and safely. Through this way, it is indirectly reflected that the equipment running state at this time may have a problem, and the tunnel record information collected by the driving recorder at this time is effective. After all, if the speed is too fast, the collection of the equipment in the tunnel is also fleeting, so the running state of the equipment cannot be accurately judged.

[0057] Of course, in addition to the speed to meet the standard, it is also necessary to determine the position information of the vehicle after identification. If there is too much difference between the position where the speed is detected to slow down and the position after the identification is completed, that is, the client is too far away from the vehicle, the communication will be very unstable. Therefore, after the speed meets the standard, the position information of the vehicle within the scope of the client is determined, and the connection priority is determined through the position information. The higher the priority, the higher the connection matching probability. Of course, the nearest one does not necessarily connect successfully, but the nearest communication connection has a higher success probability.

[0058] The client is also used to obtain the tunnel record information recorded by the driving recorder on the vehicle after the communication connection with the driving recorder, and send the tunnel record information to the server;

[0059] The server is used to identify the running state of the equipment in the tunnel according to the tunnel record information, and send a maintenance signal to the remote monitoring personnel if it is identified that the equipment in the tunnel has a fault.

[0060] Embodiment Two

[0061] Compared with Embodiment One, the difference of the present embodiment is that in order to realize the rationalization of the arrangement of the client in the tunnel, a client arrangement system based on the tunnel is also proposed, which specifically comprises:

[0062] The server is also used to generate a client arrangement strategy based on the tunnel according to the tunnel basic information and the tunnel vehicle driving condition information. The tunnel basic information includes the length of the tunnel, the humidity change condition of the tunnel, and the fault rate of the equipment in the tunnel. The tunnel vehicle driving condition information includes the historical tunnel vehicle average speed, the accident occurrence probability in the tunnel, and the common accident occurrence point.

[0063] In the present embodiment, considering that different tunnels correspond to different tunnel conditions and different vehicle driving conditions, based on this, a targeted strategy is generated for the setting of the client. Specifically, the server will acquire the basic information of the tunnel according to the tunnel to be set by the client, such as the length of the tunnel, the humidity change condition of the tunnel, and the fault rate of the equipment in the tunnel. At the same time, the historical vehicle driving condition of the tunnel in the tunnel will also be retrieved from the database, including the vehicle average speed, the accident occurrence probability, and the common accident occurrence point. Of course, there is also the position where the equipment frequently fails.

[0064] Through the collection of these data, an improved genetic algorithm is used to generate an optimal client arrangement scheme.

[0065] Specifically, as Figure 2As shown, the server comprises a client arrangement module, which comprises:

[0066] A screening module, which randomly arranges the clients in the tunnel, randomly generates N initial populations, individuals of the initial populations are arrangement schemes of the clients in the tunnel, and the individuals of the initial populations are judged and screened through constraint conditions, the constraint conditions comprise a minimum distance constraint condition of the arrangement of the clients and a maximum overlap rate constraint condition of the clients, if the constraint conditions are met, the corresponding arrangement scheme is a feasible solution, otherwise it is an infeasible solution.

[0067]

[0068] Wherein, L i is the distance of the client i to the tunnel exit, L mix is the minimum distance of the arrangement of the clients; W j is the overlap rate of the clients in the individual j in the initial population, W max is the maximum overlap rate of the clients in the initial population.

[0069] An adaptability calculation module, which calculates the adaptability of the screened population, and the adaptability calculation is as follows:

[0070]

[0071] Wherein, F1 is the first adaptability, F2 is the second adaptability; D1 is the total sum of the connection influence degrees of each client in the population individual, D2 is the total sum of the distance influence degrees between each client in the population individual, M i is the average speed of the vehicle at the position corresponding to the client i, f x is the connection influence coefficient corresponding to the average speed of the vehicle at the position of the client i; L i is the distance of the client i to the tunnel exit, L max is the maximum distance of the arrangement of the clients.

[0072] A selection module, which screens the population according to the first adaptability and the second adaptability, specifically, within a preset number of iterations, the population with the first adaptability greater than or equal to a first adaptability threshold value is selected, and after the preset number of iterations is exceeded, the population with the second adaptability greater than a preset second adaptability threshold value is selected.

[0073] A crossover and mutation module, which obtains a child population through the cross and mutation of the genetic algorithm for the selected population; when the population is crossed and mutated, the corresponding cross strategy is:

[0074] Within the preset iteration number, the selected population is randomly combined in pairs, and then the number of hybrid fragments is determined according to the number of n / 2 clients corresponding to the two populations, that is, the number of the smaller number is selected as the number corresponding to the hybrid fragments this time, and then the hybrid fragments a1, a2 are selected at the preset position, and the corresponding hybrid fragments a1, a2 are hybridized. When the preset iteration number is exceeded, the selection and exchange of hybrid fragments are randomly performed.

[0075] The cycle module is used to continue to execute the fitness calculation module after obtaining the offspring population, until the preset iteration number is met, and the offspring population is output as the optimal solution set of multi-objective optimization, that is, the optimal scheme for the clients in the corresponding current tunnel. In this embodiment, the rationalization and pertinence of the client arrangement in each tunnel are realized through the setting of the client arrangement module, which greatly improves the accuracy and reliability of the client in performing the equipment running state monitoring.

[0076] The above is only an embodiment of the present application, and the common knowledge of the specific structure and characteristics in the scheme is not described too much. The ordinary skilled person in the art knows all the ordinary technical knowledge in the field of the present application before the application date or the priority date, can know all the prior art in this field, and has the ability to apply conventional experimental means before that date. The ordinary skilled person in the art can improve and implement the present scheme based on their own ability under the guidance of this application, and some typical known structures or known methods should not be an obstacle for the ordinary skilled person in the art to implement the present application. It should be noted that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
