Description

Technical Field

[0001] The invention relates to a multi-purpose integrated control device and method, belonging to the technical field of intelligent device control. Background Art

[0002] Based on AI technology, through machine learning and training, more effective event warning models can be found. However, it will take a long time and a lot of investment to realize and deploy these AI-based algorithm models and devices in the fields of road traffic and environmental protection. There is a window period before deploying AI event warning devices or similar devices. Taking traffic accident warning as an example, many types of traffic safety equipment and perception devices have been installed in my country's road traffic field. These equipment and devices are designed to solve each specific problem. Such as traffic lights, ice and snow melting devices, active induction devices, road surface perception and induction devices, etc. The above-mentioned various devices are all traffic safety equipment and traffic real-time perception devices that have been installed in the road traffic environment. The common point of these perception devices is that they can reflect the real-time status of the traffic environment from their own dimensions; the above-mentioned traffic safety equipment can solve the corresponding pain points of the traffic scene from the functional perspective of product design; at the same time, the common point of the above-mentioned traffic safety equipment and perception devices is that the real-time detection data generated or the application functions exerted are all single and only for specific individuals. Therefore, how to construct a device that can incorporate part or all of the above-mentioned perception data into its three-dimensional analysis framework, and search and discover possible upcoming events based on these real-time perception data according to the causes of historical accidents, thereby driving multiple devices to prevent these possible events has become a technical problem that the applicant urgently needs to solve. Summary of the invention

[0003] The purpose of the present invention is to provide a multi-purpose integrated control device and method. The present invention has good versatility, can be quickly assembled into an intelligent control device applied to a specific target, is suitable for a variety of application scenarios that require rapid response, and has low overall cost and is easy to deploy quickly.

[0004] The technical solution of the present invention: a multi-purpose integrated control device, comprising:

[0005] An interface unit, used to connect with the equipment and sensing devices at the application site;

[0006] Communication module, used to achieve real-time interaction with the cloud and / or upper control equipment;

[0007] Static list is an algorithm model for processing specific events, which is used to refer to past events and classify and edit the causal data of the events;

[0008] A dynamic list is used to provide real-time data of sensing devices to the static list;

[0009] The processing unit is used to compare the fitting inducement data with the real-time data, issue corresponding instructions according to the comparison and fitting results, and control and / or drive the equipment on site to provide feedback according to the instructions.

[0010] In the above-mentioned multi-purpose integrated control device, the real-time data in the dynamic list and the inducement data in the static list are contrastive, comparable and fit; the contrastiveness means that the properties of the real-time data in the dynamic list are consistent with those of the inducement data in the static list; the comparability means that the real-time data in the dynamic list and the inducement data in the static list can be quantitatively compared; the fit means that some key data constituting the events in the static list and some data in the dynamic list can form a relatively complete combination and realize embedded contrast.

[0011] The aforementioned multi-purpose integrated control device has a built-in event warning mode list and / or control mode protocol based on local equipment, and then drives the local equipment to issue targeted event warnings to the target based on the warning level requirements given by the comparison and fitting results of the dynamic list and the static list according to the warning mode that the local equipment can issue.

[0012] The aforementioned multi-purpose integrated control device, the interface unit is provided with an editable communication protocol library and a sniffing function; the editable communication protocol library is used to define a unique code for each third-party device that has been stored in the library; the sniffing function is used to sniff and compare and fit the third-party devices that have been connected, and through sniffing and comparison and fitting, find the communication protocol that is already available in the library and load the corresponding communication protocol. If the sniffing does not find the communication protocol that has been stored in the library, the sniffing function will issue a prompt to the upper-level control device to wait for manual processing according to the preset process.

[0013] The aforementioned multi-purpose integrated control device, the real-time data in the dynamic list and the inducement data in the static list are accurately metered or measured based on a common reference environment and / or reference time and / or reference coordinates and / or approximate meteorological environment and / or approximate traffic environment and / or reference measurement values, and the real-time data generated based on the same and / or approximate basic data and / or similar continuous coordinates are compared and fitted.

[0014] The aforementioned multi-purpose integrated control device, the dynamic list is embedded with unique codes of different types of sensing devices and contains explanations of the codes, and the dynamic list classifies and coordinates the morphological parameters and application scenarios of the sensing devices according to the codes; the multi-purpose integrated control device identifies the connected equipment and sensing devices according to the explanation content contained in the dynamic list code, and determines the environment where the multi-purpose integrated control device is located based on the code, and calls the static list of the corresponding scene according to the code provided by the connected sensing device.

[0015] For the aforementioned multi-purpose integrated control device, when the data obtained by the sensing device does not match the inducement data in the static list, the processing unit will edit it into a new warning list according to its function definition. The warning list only sets the corresponding warning threshold according to the setting definition of the sensing device and the data depth. When the warning threshold is reached or exceeded, the corresponding warning information will be issued according to the connected equipment.

[0016] The aforementioned multi-purpose integrated control device recreates a new accident warning recognition model based on all the information received from the sensing device and known related knowledge, and the accident warning recognition model is defined as an innovation list; the multi-purpose integrated control device performs multi-dimensional analysis on the real-time data received based on the innovation list, and discovers new event warning entry points based on this, which are used to control and / or drive new equipment on site to provide feedback.

[0017] The aforementioned multi-purpose integrated control device also includes a functional module interface for directly controlling third-party equipment.

[0018] The aforementioned method of the multi-purpose integrated control device, when installed, connects the interface unit to the equipment and sensing device on site, and then refers to the events that have occurred in the past and classifies and edits the causal data of the induced events to form a static list;

[0019] When in use, the real-time data of the sensing device is received to obtain a dynamic list, and then the processing unit compares the fitting inducement data with the real-time data, makes corresponding instructions according to the comparison and fitting results, and controls and / or drives the equipment on site to provide feedback based on the instructions.

[0020] Compared with the prior art, the present invention is a multi-purpose hardware device based on a built-in editable event processing list. It can quickly build intelligent devices applied to specific targets based on a built-in static list (or called an event trigger threshold list, which can also be understood as an algorithm model for processing specific events) and a dynamic list (which can also be called a multi-dimensional real-time data list, which comes from the real-time data provided by various sensing devices connected to the device, and can also be understood as a data source that drives the algorithm model to make corresponding actions), so as to achieve direct application in multiple fields. The device can be applied to the fields of road traffic, environmental protection detection, etc., and can detect possible events and issue early warnings in advance. In addition to the static list, the device can also analyze additional data according to the editable event processing process (event list) based on the preset event analysis list, and can also issue early warnings in time when event symptoms occur. The different lists built into the device will determine the professionalism and specificity of the device, and when the environment, sensing device, and equipment change, it only needs to simply replace the static list inside the device to adapt to the new working environment without replacing the entire set of equipment, which has the advantages of simple and convenient operation and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 The figure is a schematic diagram of the application process of the device in a specific example of the present invention. DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0023] Embodiment 1: A multi-purpose integrated control device, comprising:

[0024] An interface unit, used to connect with the equipment and sensing devices at the application site;

[0025] Communication module, used to achieve real-time interaction with the cloud and / or upper control equipment;

[0026] Static list is an algorithm model for processing specific events, which is used to refer to past events and classify and edit the causal data of the events;

[0027] A dynamic list is used to provide real-time data of sensing devices to the static list;

[0028] The processing unit is used to compare the fitting inducement data with the real-time data, issue corresponding instructions according to the comparison and fitting results, and control and / or drive the equipment on site to provide feedback according to the instructions.

[0029] The multi-purpose integrated control device (hereinafter referred to as the device) is an intelligent event warning device that fills the window period of the AI ​​warning model. It is used to quickly assemble intelligent devices applied to specific targets (such as traffic accident warning devices, environmental protection detection warning devices, etc.), and realize direct application in multiple fields. For example, it is used to detect possible traffic accidents and issue warnings in advance. For example, when it is used to perceive that environmental indicators exceed a threshold, it can issue a warning to a specific target while also driving the corresponding control or processing device to perform related operations.

[0030] A specific description is given in the field of transportation. In this embodiment, the device has a multi-mode hardware interface (interface unit) that can be configured as needed. According to the requirements of the on-site equipment or sensing device, the device can be interconnected with the on-site traffic safety equipment and / or sensing device by increasing or decreasing the number of interfaces and / or changing the interface specifications and communication protocols (sensing devices refer to various types of sensing devices related to traffic). In order to facilitate the connection with the traffic safety equipment, the interface unit of the device is provided with an editable communication protocol library on the premise of having standard hardware specifications. The protocol library module defines a unique code for each third-party device that has been stored in the library. The interface of the device has a sniffing function, which can sniff and compare and fit the third-party devices that have been connected. Through sniffing and comparison and fitting, it searches for the communication protocol that is already available in the library and loads the corresponding communication protocol. If the sniffing does not find the communication protocol that has been stored in the library, the sniffing function will send a prompt to the upper control device to wait for manual processing according to the preset process.

[0031] The device has a built-in 4 / 5G-based mobile communication module, which can ensure real-time interaction between the device and the cloud and / or upper control equipment. The cloud can be a cloud server such as Alibaba Cloud, Tencent Cloud, Huawei Cloud, etc.

[0032] The device has an editable static list that can be loaded on demand. In the field of transportation, a static list is a way to classify the main causes and auxiliary causes of past road traffic accidents according to universal external conditions such as environment, season, and scene, forming a multi-dimensional description of data and / or curve tables, which can realize a threshold set for triggering specific events, that is, an algorithm model for processing traffic events. When calling a static list, the first thing is to confirm that the current environment and conditions (such as climate, temperature, humidity, visibility, and then road conditions, geographical conditions, etc.) are consistent with the environment and conditions described in the static list, and then call the cause of the accident (divided into main factors and auxiliary factors).

[0033] The device is used together with the traffic safety equipment installed on site (the traffic safety equipment includes but is not limited to roadside or road surface guidance devices, roadside or gantry variable information boards, roadside or road surface ice and snow melting devices, road surface automatic cleaning devices, warning lights, signal lights, tunnel guidance devices, road opening and closing devices and tunnel locking devices) and sensing devices (the sensing devices are various sensors, and the data obtained include but are not limited to road surface dryness and humidity, snow accumulation and snow thickness, ice and ice thickness, temperature drop slope (temperature change efficiency in integer unit time, measured when the temperature is below 6 degrees Celsius), road surface dryness and humidity change efficiency (road surface When the humidity starts to change, the detection is started. Within the time unit of minutes, the road humidity change efficiency, visibility value, rainfall, speed, vehicle type, lane occupancy, headway, speed variable (speed change per unit time), congestion, slow driving, collision with guardrails, road illumination, vehicle driving direction, road surface waterlogging, time speed variable (speed change in a specific section within 24 hours with the average speed per hour as the unit), emergency stop events, parking events and the current status of road surface closing equipment, etc. are directly interacted to collect real-time data related to the static list and form a dynamic list with the same rules as the static list. The dynamic data in the dynamic list is comparable, comparable and fitting with the causal data in the static list. Comparability means that some parameters in the dynamic list are consistent with the attributes of the accident cause parameters in the static list, comparability means that the relevant data in the dynamic list and the static list can be quantitatively compared, and fitting means that some key data constituting the accident in the static list and some data in the dynamic list can form a relatively complete combination and realize embedded comparison.

[0034] The processing unit of the device compares the real-time data in the dynamic list with the cause data in the static list item by item, and the successfully matched data is included in the area to be fitted. When multiple accident causes or key main accident causes are successfully matched, they are fitted with similar accident causes in the static list, and the warning level and the channel and mode for issuing warning information are determined based on the degree of fitting. Since these warnings are predicted in advance through real-time data, it is possible to issue targeted warnings to target vehicles or traffic participants before a traffic accident occurs.

[0035] Furthermore, since the types of real-time traffic-related data and the detection depth that the sensing device can detect are developing rapidly, and the static list belongs to historical data, in most cases the data categories and data depth in the dynamic list will be different from those in the static list; these data categories that are different from the static list or the deeper real-time data cannot be directly compared and fitted with the static list, which requires redefining or transforming the data, and extracting new data that can be compared with the static list according to the data specifications of the static list; if it is impossible to directly apply the data in the dynamic list that is completely inconsistent with the static list, then it is necessary to discover new data application points from these data that are inconsistent with the static list, such as setting up displacement sensors on bridges and other application modes (see Example 5).

[0036] Furthermore, the device is connected to the cloud through a built-in data link, and receives the latest static list from time to time through the cloud and / or locally. The device is interconnected with different types of traffic safety equipment and perception devices on site through a built-in interface and / or gateway. A real-time dynamic list of the traffic environment composed according to the static list rules is built into the device, and the dynamic list and the static list have a corresponding relationship with each other (the content and data of the static list are formed based on the statistics of verifiable historical data of all seasons and all environments, and the classification and data will be relatively comprehensive, while the dynamic list is subject to the types of perception devices, seasons and the number of perception devices available on site. Usually, the data types and quantities of the dynamic list will be less than the current static list). Specifically, according to the rules of accident cause classification, the device organizes the traffic safety equipment and perception devices on site into a dynamic list (for example, meteorological type, pavement type, vehicle type, rule type, interactive type, delivery type, etc., and dynamic means that the data in its list changes with the real-time I / O changes of the traffic safety and perception devices).

[0037] Furthermore, some or all of the values ​​in the sensing device collected by the present device will be consistent or similar to some categories in the static list, and these consistent or similar real-time data can provide the present device with basic data for accident warning; in short, the present device has historical statistical data (static list) on the causes of traffic accidents in different scenarios, and the data is application scenario-oriented, and each static list points to a traffic environment, such as urban intersection environment, highway ramp environment, highway main road environment, etc. At the same time, it can also collect real-time detection data (dynamic list) of the sensing device in real time, and compare and fit the static historical accident data with the current dynamic real-time data (and vice versa), so as to find the historical accident data reproduction environment closest to the accident in the dynamic list, or find the real environment where traffic accidents are more likely to occur, and based on this, it can directly drive the traffic safety equipment to issue an accident warning.

[0038] Furthermore, the device also has a built-in accident warning mode list and / or control method list (or protocol) based on local traffic safety equipment. It can drive the on-site traffic safety equipment to issue targeted accident warnings to the target road section or vehicle based on the warning level requirements given by the comparison and fitting results of the dynamic list and the static list according to the warning modes that can be issued by the traffic safety equipment installed on site.

[0039] Furthermore, the interaction between this device and the perception device uses satellite time or similar precise standard time as a common reference time, and the interaction with the traffic safety warning equipment must be based on a common reference time to achieve the warning function under the premise of achieving communication; when using a dynamic list to compare the relevant dimensional parameters in the static list, it is also necessary to be based on a common reference environment and / or reference time and / or reference coordinates and / or approximate meteorological environment and / or approximate traffic environment and / or reference measurement values ​​to achieve more accurate measurement or measurement, and to achieve comparison and fitting based on the real-time data (dynamic variable data) generated by the same and / or similar basic data and / or similar continuous coordinates. In short, the comparison and fitting can only be implemented when they are relevant.

[0040] Furthermore, the interaction between this device and various sensing devices installed on site corresponds to the traffic environment where the sensing devices are located. The dynamic list embeds unique codes of different types of sensing devices and contains explanations of the codes. The dynamic list classifies and coordinates the morphological parameters and application scenarios (traffic environments) of the sensing devices according to the codes. This device identifies the connected traffic safety equipment and sensing devices based on the explanations contained in the dynamic list codes and determines the traffic environment (such as national and provincial roads or highways or urban roads) where this device is located based on these codes; this device calls the static list of the corresponding scene based on the code provided by the connected sensing device.

[0041] Furthermore, after the device is connected to the sensing device, some of the data obtained by the sensing device and the traffic safety equipment will not match the content of the static list. These data cannot be used for comparison and fitting of the static list due to their category, data format or data depth. At this time, these data can be edited by the processing unit of the device into a new warning data source according to its role definition and realize a new warning of traffic accidents. For example, there are a large number of bridges in the road traffic environment. In the past, these bridges did not have relevant sensing devices to sense their traffic status. It is known that sensing devices have been set up in a large number of road traffic bridges to sense whether the bridge traffic is interrupted unexpectedly. If a collapse interruption occurs, the sensing device will immediately start the warning device in the traffic safety system to issue a real-time warning to traffic participants. In short, the items that are not in the static list but in the dynamic list can be edited for the device according to the preset definition of the sensing device (the warning list refers to the warning threshold list created according to the needs and on-site technical conditions). The warning list will not be compared with the static list. The corresponding warning threshold is only set according to the setting definition of the sensing device and the data depth. When the warning threshold is reached or exceeded, the corresponding warning information is issued according to the information delivery capability of the traffic safety equipment that has been connected to the device.

[0042] Furthermore, before using AI technology, in addition to the static list inside the device which is a simulation algorithm for analyzing signs of traffic accidents, the device can also recreate a new accident warning recognition model based on all the information that can be received from the sensing device and known related knowledge, and conduct multi-dimensional analysis of the dynamic traffic data that is connected based on these new traffic accident warning models, and thereby discover new traffic event warning entry points. These new warning entry points may not yet have targeted warning release devices (such as highway follow-up warning information precision delivery devices). At this time, a direct management protocol for new traffic safety equipment can be embedded in the device so that the new traffic safety equipment can be directly driven. The accident warning list that is innovatively set up in this type of application (that is, recreating a new accident warning recognition model) is called an innovation list in this device,

[0043] Furthermore, this device is positioned as an integration + management device at the traffic scene, and its management authority is at the second level (the highest level of control authority is manual control). Its functional positioning is traffic accident warning, and it will only intervene in the management and control of lower-level equipment when it identifies an impending traffic accident. When connected to lower-level equipment and no control instructions are issued, this device will not affect the normal operation of the lower-level equipment.

[0044] Furthermore, the device is also provided with functional module interfaces that can be added independently, such as a voice generation module interface (converting text directly into voice), a voice transmission module (for example, compressing the voice and then exchanging / connecting it to the on-site loudspeaker via a link or directly realizing voice synthesis on-site), and an output control interface module (for example, analog quantity control, switch quantity control, etc. interfaces, so as to be able to directly control third-party devices). These expansion interfaces are connected through the bus inside the device and realize function selection through a simple two-dimensional table mode during function configuration.

[0045] Furthermore, the device has multiple application modes, that is, it can be a superior management device for multiple traffic safety equipment, it can also be an information collection and analysis device for multiple sensing devices, and it can also be a superior control device for warning of traffic accidents based on preset algorithms; the conversion of these functions and identities is based on its built-in algorithm model (static lists, dynamic lists, innovative lists, etc. can also be understood as an algorithm model based on specific goals). Different algorithm models determine the functions and technical indicators of the device, and its hardware is the same, which provides a low-cost intelligent decision-making support device for traffic accident warning, and also provides a way to low-cost upgrades of various sensing devices and traffic safety equipment already installed at traffic scenes.

[0046] Furthermore, the present device implements event analysis, judgment and early warning based on reference time and continuous or related coordinates. If the on-site sensing device and traffic safety equipment have real-time remote interaction capabilities (such as 5G-based network interaction capabilities), the present device can remotely manage single-point or multi-point traffic scenes and provide accident early warnings. Based on this remote management and control capability, the present device can be installed in a monitoring center, and its performance is basically the same as that installed on-site.

[0047] Embodiment 2: This embodiment provides a specific application mode based on the device in Embodiment 1, such as Figure 1 The specific steps are as follows:

[0048] Step 1: Start the early warning detection function;

[0049] Step 2: Match the current traffic operating environment and conditions in the static list (for example, in winter, call the static list winter multi-dimensional data);

[0050] Step 3: Call and continuously refresh the real-time data of the dynamic list that matches the static list according to the preset step length;

[0051] Step 4: Compare the incentive data of the static list with the real-time data of the dynamic list. If the similarity is greater than 75%, the comparison is successful and proceed to step 5. Otherwise, continue to wait for a new round of real-time data.

[0052] Step 5, determine the warning level. If the fitting success data is less than 60%, turn off the warning; if the fitting success data is 60%, issue a warning and return to step 3 to continue the cycle detection; if it is between 60-80%, increase the warning level and return to step 3 to continue the cycle detection; if it is greater than 80%, issue the highest warning and return to step 3 to continue the cycle detection.

[0053] This embodiment describes a detection process that is executed after the early warning detection function of this device is activated. This process is initiated when the sensing device finds a major dynamic target (a major dynamic target refers to a traffic participant found in the detection area, which can be any participant that can be found by the sensor and may be involved in a traffic accident or danger). After initiation, this process will continue to loop and compare. When the conditions for issuing an early warning signal are met, the corresponding early warning information will be issued according to the preset process. If the degree of fit continues to increase, the early warning level will also increase accordingly. Conversely, when the degree of fit does not meet the threshold, the early warning will be stopped. This process is a tracking detection process for one target and belongs to a single thread. The integrated low-power control device allows multi-threaded parallel detection, that is, it runs in the detection section to implement follow-up detection of multiple targets and conduct targeted early warnings.

[0054] Embodiment 3: This embodiment provides a specific application case based on the device in Embodiment 1. This embodiment uses traffic safety equipment and sensing devices produced by the same enterprise. The traffic safety equipment installed on site mainly includes three-color edge induction device, static text prompt device, dynamic synchronous text display device, roadside display screen, gantry display screen, automatic spraying ice and snow melting system; the sensing devices mainly include: vehicle passing detector, vehicle speed detector, lane occupancy detector, vehicle interval distance detector, road surface dryness and humidity sensor, road surface ice sensor, road surface ice thickness sensor, road surface snow sensor, snow thickness sensor, rain and rainfall sensor, road surface brightness sensor, wind speed sensor, traffic camera, etc.

[0055] The three-color edge induction device, static and dynamic text display devices in the above-mentioned traffic safety equipment are the same system and have an external communication interface; the roadside display screen is an independent device and has an external communication interface; the gantry display screen is also an independent display device and has an external communication interface; the ice and snow melting system is also an independent traffic safety equipment, which is connected to the upper system through its built-in independent communication interface.

[0056] The sensing devices (various sensors and detectors) are distributed in five independent systems (most of which are included with the three traffic safety equipment mentioned above, and the other two are independently added sensing devices). However, these five systems all have independent or shared external communication interfaces, and because of their different application focuses, their native interfaces and communication protocols are also different.

[0057] The communication protocol for the above-mentioned traffic safety equipment and perception device can be obtained by conventional technical means. This embodiment (in order to facilitate the access of third-party data sources in the future, the name of this device used in the project is "low-power controller", which is the same product as this device) adopts a standardized interface solution, and a set of standardized communication protocols are specially defined for various devices to access this device, which includes: handshake and verification, access device type (traffic safety or perception device), main capabilities (including perception type definition, perception scale definition, measurement unit definition, data timestamp, traffic safety type definition, traffic safety function definition, traffic safety font library definition, special graphic library definition, consumables remaining detection, consumables consumption per unit time, device status code, etc.); because it is interconnected in self-produced equipment and devices, the interaction and coordination between each other is relatively convenient, so there is no need to create a communication protocol library, only need to adjust or modify the accessed communication protocol to achieve the adjustment of functions or indicators.

[0058] This device is installed in a roadside chassis in the middle section of the road where the above-mentioned traffic safety equipment and sensing device installation points are installed, and is powered by solar energy. Since the three sets of traffic safety equipment that have been installed on the roadside in the early stage are independent of each other locally, these three sets of equipment are connected to the same set of upper control systems through mobile communication modules; the five sets of sensing devices also interact with the upper control device. In summary, a total of 8 sets of equipment are interconnected with the upper control system through the corresponding gateway. From the upper computer side, each set of equipment has its own independent IP address, so this device is also connected to the upper control system through the wireless communication module to interact with these 8 sets of equipment and devices.

[0059] Each data source and / or application function loaded into the dynamic list of this device defines a unique coordinate address and / or detection line, which coincides with the coordinate point of the sensing device. These continuously arranged detection lines form a continuous starting point and / or end point in the detection process, so that when this device receives any data, it can trace back or detect the time, coordinates and time taken for the target to reach the next detection line (coordinates) when the data is generated. At the same time, these continuous coordinates or detection lines are also used as distance measurement units. The distance between these detection lines can be parameterized in practical applications. For example, the relative distance between detection lines needs to be shorter in urban applications, and the distance between detection lines can be longer when applied on highways or national and provincial roads. Similarly, each data generated by different perception categories in the five sets of perception devices will be accompanied by at least one coordinate and timestamp, so that this device can effectively compare and fit based on these data.

[0060] The main contents of the static list include relevant data that can be identified and recorded when a traffic accident occurs, such as vehicle speed, vehicle type, road slipperiness, road shape (curve or straight road, horizontal road surface or uphill or downhill), visibility value, accident type (such as rear-end collision, collision, roadbed run-off, rollover, etc.), etc., and some well-known research data are also added, such as braking distance of different vehicle types, braking distance of different loads, acceleration curves of different vehicle types and different loads, side slip degree at different steering angles at different vehicle speeds, etc. In order to compare with the dynamic list, the data sequence of the corresponding category in the static list and the dynamic list (data of different categories and subjects cannot be compared and fitted). Based on the static list of the main and auxiliary causes of the accident, the device performs real-time rolling comparison with reference to the real-time data corresponding to the dynamic list. For example, based on the current road adhesion derived from the wetness of the road (this knowledge is public knowledge and is only quoted here), the shortest braking distance of different types of vehicles can be known based on the derived road adhesion. If it is found that the vehicle entering the detection section cannot stop in front of the obstacle at the current speed, the corresponding warning is activated in advance. Of course, the warning level will also increase synchronously as the distance to the obstacle gets closer (the countdown time is shorter).

[0061] This device can simultaneously detect the speed, lane occupancy, road surface slipperiness, obstacle coordinates and other data of multiple target vehicles entering the detection section through the sensing device, and the measurement of this device is carried out in a rolling manner when any target vehicle is running in the detection area until the target vehicle drives out of the detection area; because the computing power setting margin of this device has taken into account the multi-target rolling calculation requirements required when multiple vehicles pass through the detection area at high speed, this device can meet the needs of multi-target accident warning.

[0062] This device is used in the "ice melting system". In winter, the ice and snow melting system can predict the ice on the road surface based on the sensing device (currently, the possible ice on the road surface can be predicted 3 hours in advance). The original prediction function of the ice and snow melting device allows the ice and snow melting system to pre-dispense the ice and snow melting agent in advance, and can pre-spray before the road surface freezes, so as to effectively lower the freezing point. This process will continue until the ambient temperature drops to a level that exceeds the working capacity of the ice and snow melting system. In this process, after adding this device, vehicles traveling on this road section can learn in real time that this road section will not freeze within the future predicted time, and can also prompt the vehicle's current safe speed value. When summer comes, if the road surface temperature is too high, the road surface adhesion will also be reduced (some road surface coverings will soften or melt). In this case, the device collects the real-time road surface temperature and analyzes the temperature rise curve. When the road surface is close to the high-temperature softening point, the device will start the ice and snow melting device to spray water on the road surface to reduce the road surface temperature and prevent the road surface from softening. When spraying water to cool down, the device will also start the display device to remind passing vehicles that watering operations are currently being carried out, so please pay attention to safety.

[0063] The real-time data provided by different sensing devices can be professionally combined to analyze a variety of possible combinations of factors that may cause traffic accidents. These factors can be gradually added to the early warning list after being verified and mature (the early warning list contains identifiable accident hazards and early warning prompts, and is a list of dynamically changing content).

[0064] Actual warning case: This device was tested on site in Shanxi. The installation point was a highway with an ambient temperature of about 8 degrees Celsius. The sensor showed that there was a water film of about 3 mm thick on the road surface, and the road shape was a downhill slope with an arc. The static list data showed that under the above environmental and road conditions, there would be a risk when the maximum speed of small vehicles on this section exceeded 85 km / h or higher, and the risk would increase sharply after exceeding 100 km / h. An induction device was installed 2,500 meters forward in both directions from the turning point on this section. The induction device includes vehicle inspection devices and lane occupancy detectors, vehicle type / speed detectors, traffic cameras and other sensors that are evenly spaced at intervals of 25 meters. The traffic safety equipment is the three-color warning light, static character display and dynamic character display module, roadside display screen and accompanying speakers configured by the induction device. The warning record of this device shows that at about 22:00 in the evening, a small car was detected at the initial detection line at 122 kilometers per hour passing the first detection line and maintaining this speed. After passing three detection lines in succession, the speed did not change. At this time, this device called the photo of the car taken by the camera through the interface according to the warning information and warning mode given by the static list and displayed it on the roadside display screen, and simultaneously displayed the emergency speed reduction prompt at the bottom of the display screen, and lit up the characters on the roadside induction device to prompt the car to slow down; when the car passed the starting detection line for about 1000 meters, the speed had dropped to about 90 kilometers, and the subsequent prompt was 80 kilometers. The speed of the car had dropped to about 75 kilometers when entering the curve and then passed the curve. The text prompt warning on the roadside display screen after the curve was lifted. In this warning process, the device collects that the safe driving speed of the current section must be lower than the value given by the static list. Vehicles entering at a speed higher than this value will trigger a warning. Displaying the vehicle photo is a fixed-point warning prompt, and displaying static text is to prompt the driver as soon as possible. Since the vehicle detectors of the induction device are installed at intervals of 25 meters, the device can continuously learn the speed changes in real time. Assuming that the speed of the warned vehicle does not change within the predetermined countdown time, the device will drive the induction device to dynamically display the warning characters (relative to the static display of the vehicle) to improve the warning efficiency. It will also start the speaker installed in the roadside display screen to warn the vehicle (the speaker is only installed on the road section that will not disturb the public, so it is not popular in actual application).

[0065] This embodiment mainly illustrates that the device integrates different traffic safety equipment and sensing devices into one system and sets the current safe driving conditions according to the static list, and uses the dynamic list to detect whether the passing vehicles exceed the safety threshold provided by the static list. If not, the device will not be triggered. If the dynamic list data shows that a vehicle exceeds the safety threshold, the corresponding traffic safety equipment will be activated to initiate a targeted warning.

[0066] Example 4: This example provides a specific application case based on the device in Example 1. This example describes the configuration mode using third-party traffic safety equipment and sensing devices. The key to this example is how to effectively connect third-party equipment and devices to this system:

[0067] Traffic safety equipment. The traffic safety equipment that this device is intended to connect to is the roadside display screen, controllable contour marker, gantry display screen, and tunnel entrance indicator light produced by a third party. The method is that the owner asks the third-party equipment manufacturer for the communication protocol of its equipment and requires the other party to provide an identifiable identification code during the handshake. A three-digit device code consisting of letters and numbers is set for the device or device in the communication protocol library (the device code defines the device type, application scenario, and serial number, respectively). Under the device code, a corresponding communication protocol is created and the use of the device is marked. In actual use, the device is operated according to the corresponding usage requirements. If the other party has the ability to display graphics or characters but does not have a font library, the display font or graphic dot matrix is ​​directly provided by this device when called.

[0068] Sensing device: The third-party equipment manufacturer uses the interface protocol (communication protocol) of the sensing device, the device identification code and usage method, detection depth (or detection accuracy and error), application scenarios and other background information. The communication protocol library creates a 4-digit identification code consisting of letters and numbers for the device or similar devices. The letters and numbers of the identification code represent the application information and device accuracy (detection depth), status identification and other key information that the connected device must provide. The communication protocol library has a version number so that it can be added when a new communication protocol is obtained or updated as soon as possible when the original protocol is changed.

[0069] When the device detects that a third-party device is connected, it reads the identification code provided by the other party during the handshake and searches for the corresponding information in the communication protocol library. When the information in the library matches the identification code, the data provided by the interface is returned to the corresponding position in the dynamic list according to the definition in the protocol and provided to the upper control device as well as the type and status of the connected device.

[0070] Unrecognized access: When the interface cannot identify the third-party device that is accessed, the interface is locked and a prompt is sent to the host computer.

[0071] After the device is connected to a third-party device, its operation method is consistent with that in Example 3.

[0072] Embodiment 5: This embodiment provides a specific application case based on the device in Embodiment 1. Since the technology and detection accuracy of the sensing device are changing with each passing day, the device of this embodiment is suitable for temporary emergency application scenarios: for example, bridges in the field of road traffic will encounter sudden dangerous situations during the flood season. At present, most similar sections of roads have not developed special equipment for such uncommon dangerous situations. This embodiment is to set a bridge collapse emergency warning device on a bridge, which can timely block subsequent vehicles from entering the dangerous area when a major accident occurs on the bridge. The specific method is to install displacement sensors and / or vibration sensors at the joints of the bridge plates and weak environments, and stress sensors can also be installed at key parts of the bridge. At the same time, a warning signal display screen is set about 1000 meters or more away from the front of the bridge. These sensors are connected to this device through a link, and the warning signal display screen is also connected to this device. The static list in this device gives the danger threshold, while the dynamic list perceives the field data in real time through the sensor and compares it with the threshold of the static list. When the value of the dynamic list exceeds the preset threshold, the preset warning device is called and the predetermined warning mode is started.

[0073] The present embodiment is intended to illustrate that the present device is an intelligent device that defines the functions and working thresholds of on-site equipment based on a multi-dimensional editable list. It can use common sensing devices (sensors) and interactive devices or information delivery devices on the market to quickly form a device or system with a predetermined function on site. This ability to quickly assemble intelligent devices can be applied in more scenarios, and currently the time and cost of completing deployment of the present device is more convenient and less costly than developing dedicated equipment.

[0074] The above embodiments only express the implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
