Obviously, the drawings in the following description are only embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying any creative work.

[0053] Figure 1 It is a functional block diagram of a self-diagnosis and alarm intelligent management system based on traffic equipment failure of the present invention. DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] like Figure 1 As shown, the present invention provides a self-diagnosis and alarm intelligent management system based on traffic equipment failure, including:

[0056] The detection module is arranged in the smart case, and is used to detect the operation data of the traffic equipment connected to the smart case, and the traffic equipment includes traffic lights, signal machines, electric alarms and checkpoints.

[0057] A processing module is connected to the detection module, and is used to receive the operation data detected by the detection module, pre-process the operation data, determine whether the traffic equipment fails according to the pre-processed operation data, and diagnose the type of failure.

[0058] A management module is connected to the detection module and the processing module, and is used to manage the intelligent chassis.

[0059] An alarm module is connected to the management module, and is used to generate a fault alarm according to the judgment result of the processing module.

[0060] A display module is connected to the management module, and is used to display a location map of the smart chassis.

[0061] It is understandable that the smart chassis can be connected to traffic technology equipment of different brands and models to achieve unified management and monitoring of these devices. The smart chassis uses modular components and pre-installed quick-install interfaces for easy maintenance and repair. The self-diagnosis and alarm intelligent management system based on traffic equipment failure is used to uniformly manage the basic information, monitoring data, alarm information, and intersections of traffic equipment. Based on digital twin technology, it simulates the operation of real intersections, traffic lights, signal machines, electric police, checkpoints, power distribution cabinets, and smart chassis, provides intuitive visualization effects, realizes data mapping and two-way interaction between reality and virtuality, and improves the flexibility and convenience of road traffic technology equipment management.

[0062] In some embodiments of the present application, the detection module includes: a current transformer for detecting the current value of the traffic equipment; a voltage transformer for detecting the voltage value of the traffic equipment; a main-standby power switching unit for detecting whether the smart chassis performs a power switching operation; a lightning arrester for detecting whether the smart chassis performs a lightning protection operation; a circuit breaker for detecting whether the smart chassis performs a power-off operation; a temperature and humidity sensor for detecting the temperature and humidity values ​​of the environment in which the smart chassis is located; a liquid level sensor for detecting the liquid level value of the environment in which the smart chassis is located; a positioning unit for detecting the installation position of the smart chassis; and a door switch detection unit for detecting the door switch status of the smart chassis.

[0063] In this embodiment, detection equipment is set up to detect the traffic equipment and the smart chassis to obtain the operation data of the traffic equipment and the smart chassis. At the same time, since the smart chassis is connected to the traffic equipment, it can also be considered that the operation data of the traffic equipment is obtained.

[0064] It is understandable that the detection module also includes a maintenance mode switch for determining whether the smart chassis is in a maintenance state.

[0065] In some embodiments of the present application, when the processing module is used to preprocess the operating data, it includes: preprocessing the operating data, the preprocessing includes missing value processing and standardization processing; converting non-numeric data in the operating data into numerical data, specifically: if the smart chassis performs a power switching operation, the power switching data is set to 1, if the smart chassis does not perform a power switching operation, the power switching data is set to 0; if the smart chassis performs a lightning protection operation, the lightning protection data is set to 1, if the smart chassis does not perform a lightning protection operation, the lightning protection data is set to 0; if the smart chassis performs a power-off operation, the power-off data is set to 1, if the smart chassis does not perform a power-off operation, the power-off data is set to 0; if the smart chassis is in a door-open state, the door switch data is set to 1, if the smart chassis is in a door-closed state, the door switch data is set to 0.

[0066] In this embodiment, when the processing module performs the preprocessing task of the operation data, it specifically includes the following steps: First, a series of preprocessing operations are performed on the operation data, which mainly include missing value processing and standardization processing. Missing value processing refers to identifying and filling or deleting missing data in the data set to ensure the integrity and accuracy of the data. Standardization processing converts the data into a unified format or range for subsequent analysis and processing. Next, the processing module converts the non-numeric data in the operation data into numeric data for more efficient calculation and analysis. The specific conversion rules are as follows: When the intelligent chassis performs a power switching operation, the corresponding power switching data will be set to a value of 1, indicating that the operation has occurred; on the contrary, if the intelligent chassis does not perform a power switching operation, the corresponding power switching data will be set to a value of 0, indicating that the operation has not occurred. Similarly, when the intelligent chassis performs a lightning protection operation, the lightning protection data will be set to a value of 1, indicating that the operation has been performed; and when the intelligent chassis does not perform a lightning protection operation, the lightning protection data will be set to a value of 0, indicating that the operation has not been performed. In addition, when the smart chassis performs a power-off operation, the power-off data will be set to a value of 1, indicating that the operation has been performed; when the smart chassis does not perform a power-off operation, the power-off data will be set to a value of 0, indicating that the operation has not been performed. Finally, when the door of the smart chassis is open, the door switch data will be set to a value of 1, indicating that the door is open; and when the door of the smart chassis is closed, the door switch data will be set to a value of 0, indicating that the door is closed. Through this conversion, all non-numeric data are converted into numerical data that is easy to process and analyze.

[0067] It is understandable that, since the operating data includes non-numeric data, in order to ensure the accuracy and convenience of subsequent data processing, the non-numeric data is converted into numerical data to facilitate the fault diagnosis of the intelligent chassis.

[0068] In some embodiments of the present application, when the processing module is used to determine whether a smart chassis has a fault based on the preprocessed operating data and diagnose the fault type, it includes: presetting an operating data threshold, the operating data threshold includes a current lower limit threshold, a current upper limit threshold, a voltage lower limit threshold, a voltage upper limit threshold, a temperature threshold, a humidity threshold and a liquid level threshold; comparing the preprocessed operating data with the operating data threshold, determining whether a fault has occurred based on the comparison result, and diagnosing the fault type; if the current value is greater than or equal to the current lower limit threshold, and the current value is less than or equal to the current upper limit threshold, it is determined that the traffic equipment has not failed; if the current value is less than the current lower limit threshold, or the current value is greater than the current upper limit threshold, it is determined that the traffic equipment has a fault, and the fault type is determined to be a current fault; if the voltage value is greater than or equal to the voltage lower limit threshold, and the voltage value is less than or equal to the voltage upper limit threshold, it is determined that the traffic equipment has a fault. No fault has occurred; if the voltage value is less than the voltage lower limit threshold, it is determined that the traffic equipment has a fault, and the fault type is determined to be a voltage undervoltage fault; if the voltage value is greater than the voltage upper limit threshold, it is determined that the traffic equipment has a fault, and the fault type is determined to be a voltage overvoltage fault; if the temperature value is less than or equal to the temperature threshold, it is determined that the ambient temperature of the smart chassis is normal; if the temperature value is greater than the temperature threshold, it is determined that the ambient temperature of the smart chassis is abnormal, and the fault type is determined to be a temperature abnormality fault; if the humidity value is less than or equal to the humidity threshold, it is determined that the ambient humidity of the smart chassis is normal; if the humidity value is greater than the humidity threshold, it is determined that the ambient humidity of the smart chassis is abnormal, and the fault type is determined to be a humidity abnormality fault; if the liquid level value is less than or equal to the liquid level threshold, it is determined that the liquid level of the environment in which the smart chassis is located is normal; if the liquid level value is greater than the liquid level threshold, it is determined that the liquid level of the environment in which the smart chassis is located is too high, and the fault type is determined to be a high liquid level fault.

[0069] In this embodiment, the processing module determines whether the intelligent chassis or traffic equipment has a fault through preset operating data thresholds (including upper and lower thresholds of current, voltage, temperature, humidity and liquid level). Comparing the pre-processed current value, if the current value is between the set upper and lower limits, the traffic equipment is normal; if it exceeds the range, it is determined to be a current fault. When the voltage value is between the preset lower and upper limits, the traffic equipment has no fault; if it is lower than the lower limit, it is an undervoltage fault, and if it is higher than the upper limit, it is an overvoltage fault. At the same time, if the temperature value does not exceed the set threshold, the environment in which the intelligent chassis is located is normal; if it exceeds the threshold, it is an abnormal temperature fault. The humidity and liquid level values ​​are also compared with their respective thresholds. If they exceed the threshold, they are respectively determined to be abnormal humidity fault and excessive liquid level fault.

[0070] In some embodiments of the present application, when the processing module is used to determine whether the smart chassis has a fault based on the preprocessed operating data and diagnose the fault type, it also includes: when the power switching data is 0 or the power off data is 0, the smart chassis is set to have no fault; when the power switching data is 1 or the power off data is 1, the smart chassis is set to have a power fault; when the lightning protection data is 0, the smart chassis is set to have no fault; when the lightning protection data is 1, the smart chassis is set to have a lightning protection fault; when the door switch data is 0, the smart chassis is set to have no fault; when the door switch data is 1, the smart chassis is set to have a door fault.

[0071] In some embodiments of the present application, the management module includes: a device management unit, which is used to manage, maintain and update the equipment of the smart chassis.

[0072] The intersection management unit is used to determine the installation intersection of the smart chassis according to the installation position of the smart chassis, and manage the installation intersection.

[0073] In this embodiment, the device management unit is used to effectively manage, maintain and update the smart chassis device information connected to this system to ensure the accuracy, completeness and security of the device information. When adding new device information to this system, it is necessary to fill in the device name, device number, brand model, installation time, installation location, wiring configuration, alarm configuration, associated users and other information according to standard specifications. The installation location of the device can be automatically obtained based on the Beidou positioning of the smart chassis. The system provides flexible query conditions for quick screening and searching of all devices, and supports batch export of device information.

[0074] The intersection management unit is used to uniformly manage the intersections where the smart chassis are installed. Each smart chassis has its corresponding installation intersection. The system provides preset common intersection templates. According to the actual situation of the intersection, select the corresponding intersection template, modify the device parameters, or select the device from the device 3D model library, and configure the model size, position, angle and other parameters of the device in the intersection 3D model. Users can immediately see the effect of the adjustment.

[0075] It is understandable that the management module also includes a device model management unit and an intersection template management unit. The device model management unit is used to establish a three-dimensional model library containing various types of road traffic technology equipment, import equipment three-dimensional models (GLB format), manage device models, and support replacement and upgrading of old models in the model library. A preview function of the model is provided in the model library to display the appearance and key attributes of the model. The intersection template in the intersection template management unit is used to quickly build a three-dimensional model of the intersection where the smart chassis is located. The intersection template is managed through the system, and commonly used intersection templates are configured in advance to improve the reusability of the intersection three-dimensional model. The user uploads the intersection three-dimensional model base map (GLB format), and then adds, modifies or deletes various types of equipment in the intersection, and saves the edited template for subsequent calls.

[0076] In some embodiments of the present application, the management module further includes a fault prediction unit, and the fault prediction unit is used to predict the fault of the traffic equipment according to the operation data.

[0077] In this embodiment, the fault prediction unit uses AI to predict faults, introduces AI algorithms to analyze and predict equipment faults, analyzes and predicts possible equipment faults and times, implements advance warnings, and takes intervention measures in advance, thereby effectively reducing the probability of faults and further improving the stability and reliability of the equipment. The average, maximum, minimum, and standard deviation key features are extracted from the voltage and current history records of the traffic light, and the extracted features are combined with the normal and faulty state labels of the traffic light to construct a data set, and a model is constructed to learn the correlation between voltage and current features and traffic light faults. If the current deviates from the average and continues to rise, a fault may occur. The real-time detected voltage and current data are input into the model to analyze and determine whether a fault may occur.

[0078] In some embodiments of the present application, when the alarm module is used to perform a fault alarm based on the judgment result of the processing module, it includes: an alarm mode comparison table is set in the alarm module, the alarm mode comparison table includes several alarm modes, and the alarm mode is set with a unique corresponding fault type; when it is determined that a traffic equipment or smart chassis has a fault, based on the alarm mode comparison table, the alarm mode is determined according to the fault type; an alarm is made according to the alarm mode, and the alarm information is sent to the user.

[0079] In this embodiment, the function of the alarm module is to perform a corresponding fault alarm according to the result after the processing module completes the fault judgment. Specifically, a detailed alarm mode comparison table is configured inside the alarm module. This comparison table lists a variety of different alarm modes, each of which corresponds to a specific fault type. When the system detects that a traffic device or an intelligent chassis has a fault, the processing module will pass the fault type to the alarm module. After the alarm module receives the fault type, it will determine the corresponding alarm mode according to the internal alarm mode comparison table. This process is achieved by matching the fault type with the records in the comparison table. Once the corresponding alarm mode is determined, the alarm module will perform an alarm operation according to the mode. The alarm mode can be sound, light, screen prompt or other forms, depending on the setting of the alarm mode. In addition, the alarm module will also send the alarm information to the user. This can be achieved in a variety of ways, such as through text messages, emails, mobile phone application push notifications or other instant messaging tools. In this way, users can promptly understand the fault conditions of traffic equipment and intelligent chassis and take corresponding measures to deal with them. In this way, the alarm module ensures that the fault information can be quickly and accurately conveyed to the user, thereby improving the reliability of the system and the user's satisfaction.

[0080] It is understandable that the alarm module can automatically push the alarm information through the system message, and the corresponding intersection on the map will pop up in real time and flash brightly. At the same time, the system can send a text message to the operation and maintenance personnel based on the mobile phone number of the equipment-associated operation and maintenance personnel to notify them to handle it in time. The alarm information supports manual or automatic push to the operation and maintenance personnel, and the maintenance status of the fault can be viewed in this system. There will also be a corresponding notification after the fault is restored.

[0081] It can be seen that the alarm modes include power supply alarm, environmental monitoring alarm, water immersion alarm, lightning protection alarm and box door alarm; among them, the power supply alarm includes overvoltage, undervoltage, current, power failure abnormality, etc.; the environmental monitoring alarm includes temperature abnormality, humidity abnormality and high water level.

[0082] In this embodiment, the alarm module also includes a signal light alarm. For example, when the signal light is off, on for a long time, some of the lamp beads are off, red and green are on at the same time, and there is a countdown failure, the signal light alarm is performed.

[0083] In some embodiments of the present application, when the display module is used to display the location map of the smart chassis, it includes: a city map is stored in the display module; the installation location of the smart chassis is obtained, the installation location is displayed in the city map, and a smart chassis distribution map is generated; the smart chassis distribution map also displays the working status of the smart chassis, and the working status includes online status, offline status and fault status.

[0084] In this embodiment, the display module is designed to display the specific location map of the smart chassis. Specifically, a detailed city map is pre-stored inside the display module. By obtaining the installation location information of the smart chassis, the system can mark the location information on the city map in real time, thereby generating a smart chassis distribution map. This distribution map not only shows the specific location of the smart chassis, but also reflects the working status of each smart chassis in real time. The working status of the smart chassis includes three main types: online status, offline status and fault status. The online status indicates that the smart chassis is operating normally and can provide services normally; the offline status indicates that the smart chassis is temporarily unable to provide services, which may be due to maintenance or other reasons; the fault status indicates that the smart chassis has a technical problem and needs to be repaired or replaced. Through this real-time display function, managers can quickly understand the operating status of the smart chassis, perform corresponding maintenance and management operations in a timely manner, and ensure the stable operation of the system.

[0085] It is understandable that the map in this application can be a three-dimensional map. The distribution of the smart chassis and the operating status are determined through the smart chassis distribution map to form an intuitive overview. Different states of the equipment such as online, offline, and faulty are distinguished by different colors for easy and quick identification. Click on the intersection on the map to view the intersection details, and you can enter the three-dimensional map page of the intersection, display various types of equipment in the three-dimensional model of the intersection, simulate the actual scene of the intersection, and support map zooming, panning, rotation and other operations.
