Referring to fig. 3, fig. 3 is a schematic flow chart of an early warning method for a waste liquid transportation accident according to an embodiment of the present application. As shown in fig. 3, the method includes the following steps.
S310, when a safety accident occurs to a target waste liquid transport vehicle, generating a first early warning message, wherein the first early warning message carries a first position and first information, the first position is the geographic position of the target waste liquid transport vehicle, and the first information is license plate information of the target waste liquid transport vehicle.
The waste liquid in the present application may be an industrial waste liquid, which is understood to be a waste liquid generated by processing various products such as electronic products (display screens), for example, the industrial waste liquid may include waste stripping liquid, waste isopropyl alcohol, waste N-methylpyrrolidone, waste dilution liquid, waste etching liquid, and the like, without limitation.
For example, for a plasma display panel (Plasma Display Panel, PDP), the waste liquid may be waste acid such as waste etching liquid, stripping liquid, diluent, or the like, and waste organic solvent. For example, for a liquid crystal display (Liquid Crystal Display, LCD), a Light-Emitting Diode (LED), and an Organic Light-Emitting Diode (OLED), the waste liquid may include a waste stripping liquid, waste isopropyl alcohol, waste N-methylpyrrolidone, waste diluent, and waste etching liquid. For example, the waste liquid can be single-polycrystal wool making waste liquid.
When the waste liquid transport vehicle is subjected to safety accidents such as side turning and collision in the operation process, the waste liquid leaks and even explodes, and components which are harmful to human health possibly exist in the waste liquid, so that emergency accident treatment is required to be carried out to inform nearby vehicles and personnel to take different protective measures according to the distance degree when the waste liquid transport vehicle is subjected to the safety accidents, and casualties are avoided.
Specifically, when a safety accident of the waste liquid transport vehicle is detected, the safety early warning device can generate a first early warning message according to the current position of the target waste liquid transport vehicle and license plate information. For example, when the driver determines that a safety accident occurs and presses the trigger button, the safety warning device may generate the first warning message according to an instruction of the trigger button, or when the safety warning device detects that an accident such as leakage or explosion occurs in the waste liquid storage device, the safety warning device may generate the first warning message.
In this application embodiment, through when detecting the waste liquid transport vehicle and taking place the incident, generate first early warning message and inform the personnel that receive the influence and take defensive measure, avoid casualties to and can in time inform vehicle and personnel that will receive the influence, reduce more vehicles and personnel and get into the incident risk scope, with reduction casualties and loss.
S320, acquiring a first capacity according to the first information, wherein the first capacity is the waste liquid capacity of the target waste liquid transport vehicle.
In a specific implementation, vehicles transporting waste solutions need to be approved by national regulations for reporting hazardous waste transfer plans and are under the supervision of environmental protection authorities in real time. When the waste liquid transport vehicle has a safety accident, the safety early warning device can acquire the capacity of the waste liquid registered and transported by the waste liquid transport vehicle according to license plate information of the waste liquid transport vehicle, so that a pollution area influenced by the safety accident can be estimated according to the capacity of the waste liquid, and vehicles and personnel in the pollution area can be timely notified to carry out protection.
S330, determining a target vehicle group according to the first capacity and the first position, wherein the target vehicle group comprises a plurality of vehicles affected by the safety accident.
Because components which are harmful to human health may exist in the waste liquid, when the waste liquid transportation vehicle is in accident, the polluted area is larger and larger along with the leakage of the waste liquid, and vehicles and personnel running on the road in the polluted area may be influenced under the condition of no perception. Therefore, after the safety accident of the waste liquid transport vehicle is detected, the early warning information can be sent to the vehicle affected by the accident and the personnel on the vehicle so as to remind the vehicle to prevent and evacuate, and casualties and losses are reduced.
Optionally, the determining the target vehicle group according to the first capacity and the first position includes: acquiring a target wind direction and a target wind speed of the first position; determining a target pollution area according to the target wind direction and the target wind speed, wherein the target pollution area is an area which is harmful to human bodies; generating a plurality of pollution traveling paths according to all road sections in the target pollution area; a vehicle routed through any one of the plurality of contaminated travel paths is added to the target vehicle group.
When the waste liquid transport vehicle has a safety accident, people in the wind direction area should be notified as soon as possible, so that people in the accident area can take countermeasures in time to avoid casualties and the like.
Specifically, when a safety accident occurs to the waste liquid transport vehicle, the safety early warning device can acquire the running route and the current weather information of the waste liquid transport vehicle to determine which areas are hurt by the safety event, so that people in the accident range area can take countermeasures to avoid casualties.
The pollution degree of different areas is different along with the change of the distance between the polluted area and the waste liquid transport vehicle and the change of the wind direction, and the influence of different pollution degrees on the health of human bodies is also different, so that a target polluted area which can cause harm to the human bodies needs to be selected from polluted candidate areas.
Wherein said determining a target pollution area according to said target wind direction and said target wind speed comprises: determining at least one pollution area according to the target wind direction, wherein each pollution area is positioned in the pollution range of the target wind direction; calculating a target distance between each of the contaminated areas and the waste transport vehicle; determining a target pollution coefficient of each pollution area based on a mapping relation between the distance and the pollution coefficient; determining a target waste liquid concentration of each pollution area according to the target wind speed, the target pollution coefficient and the first capacity; and determining the pollution area with the target waste liquid concentration being larger than a first concentration as the target pollution area, wherein the first concentration is the waste liquid concentration which is harmful to human bodies.
Specifically, an administrative region that may be contaminated is determined as a contaminated region in an administrative division manner according to the current position of the waste liquid transport vehicle and the target wind direction. And then calculating the distances between a plurality of boundary points of each pollution area and the waste liquid transport vehicle, taking the average value of the distances between each boundary point and the waste liquid transport vehicle as a target distance, determining a target pollution coefficient corresponding to the target distance according to the mapping relation between the distances and the pollution coefficient, and further calculating the pollution degree of each pollution area according to the capacity, the wind speed and the pollution coefficient of the leaked waste liquid, wherein the first capacity, the target wind speed and the pollution coefficient are in a proportional relation with the pollution degree.

In a specific implementation, the concentration of the waste liquid in each polluted area is different according to the influence of the wind speed and the distance, for example, when the wind speed is small or even none, the concentration of the waste liquid is larger when the waste liquid is closer to the waste liquid transport vehicle; however, when the wind speed is high, the wind can quickly blow the waste liquid to a place farther away, the pollution area caused by the waste liquid is large, and the pollution degree can change along with the change of the wind speed. Therefore, the average waste liquid concentration of each pollution area is calculated according to the capacity of the waste liquid, and then the waste liquid concentration (namely the pollution degree) of each pollution area is adjusted according to the influence of the distance between the pollution area and the waste liquid transport vehicle and the wind speed, so that the final waste liquid concentration of each pollution area is obtained.
S340, sending the first early warning message to the vehicles in the target vehicle group.

In one possible example, the method further comprises: acquiring a plurality of target user devices and positions of the plurality of target user devices, wherein the plurality of target user devices are positioned in the target pollution area; determining the target pollution degree of each target user equipment according to the positions of the plurality of target user equipment; determining a target risk level corresponding to the target pollution level of each target user equipment according to the mapping relation between the pollution level and the risk level; and respectively executing the safety early warning operation corresponding to the target danger level to the plurality of target user equipment.
In the specific implementation, the pollution caused by the waste liquid transport vehicle also causes harm to the personnel such as households, merchants, pedestrians and the like, so that when a safety accident occurs, a first early warning message is required to be generated on the user equipment in the target pollution area so as to inform the user to defend and evacuate in time.
Specifically, the safety early warning device may acquire user equipment (such as a mobile phone) and geographic positions of all users located in the target pollution area from the mobile communication carrier server, determine the pollution area to which each user equipment belongs according to the geographic position of each user equipment, and further determine the target pollution coefficient of the pollution area as the target pollution degree of the user equipment.

Further, the method further comprises: acquiring waste liquid components of the waste liquid transport vehicle according to the first information; if the waste liquid component comprises a target component, acquiring a first image, wherein the first image is an image of the safety accident, and the target component is a component for triggering the safety accident; identifying the first image to obtain a target area of the target component; acquiring a first temperature, wherein the first temperature is the field environment temperature of the target area; determining a target defense measure corresponding to the first temperature according to the mapping relation between the temperature and the defense measure; the target defensive measure is transmitted to the plurality of target user devices and/or the target vehicle group.
When the waste liquid contains an explosive component, in order to avoid explosion or secondary explosion caused by continuous leakage of the waste liquid, the safety early warning device can acquire the component of the waste liquid according to license plate information of the waste liquid transportation vehicle, if the waste liquid contains the explosive component, a vehicle network or a mobile communication network can acquire a first image of an accident scene of the waste liquid transportation vehicle, a target area in which target components are diffused is obtained by identifying a second image, the target area of the target area can be determined, characteristic point extraction is performed on the target area, the number of characteristic points is obtained, the distribution density of the target characteristic points is determined according to the number of characteristic points and the target area, and further, the distribution density of the target components can be determined according to the target area and the distribution density of the target characteristic points, wherein the target area reflects the leakage coverage range, and the distribution density of the target characteristic points reflects the leakage degree of the waste liquid, for example, the leakage viscosity or the coverage thickness of the waste liquid, and further, the dangerous condition of the waste liquid can be accurately determined through the two dimensions.
In the specific implementation, dangerous temperatures of different waste liquid components are different, and then, a target dangerous coefficient corresponding to the current field environment temperature is determined according to a mapping relation between the field environment temperature and the dangerous coefficient, namely, the closer the field environment temperature is to the threshold temperature, the more dangerous is, and then, the corresponding threshold temperature can be determined according to the target components of the waste liquid, and then, the corresponding dangerous grade is determined based on the difference value between the field environment and the threshold temperature, so that the safety early warning operation is realized accurately, and the transportation safety of the waste liquid is ensured.
The safety early warning device can prestore a mapping relation between temperature and dangerous coefficient and a mapping relation between dangerous coefficient and preventive measures. And then a target risk coefficient corresponding to the maximum value of the field environmental temperature can be determined according to the mapping relation, and then a target defense measure corresponding to the target risk coefficient is determined according to the mapping relation between the risk coefficient and the defense measure. Because the accident range is a large range, the temperature distribution is often uneven in the range, so that the local temperature needs to be analyzed, and the early warning is carried out through the local temperature, thereby being beneficial to timely carrying out the early warning.
In one possible example, the method further comprises: acquiring at least one second temperature, wherein the second temperature is the temperature of the inner tank body of the waste liquid transport vehicle; mapping the at least one second temperature in a coordinate system, the abscissa of the coordinate system being time and the ordinate being the second temperature; fitting the coordinate points of the second temperature to obtain a fitting curve; calculating target expectation and mean square error of the fitted curve; estimating a target temperature after the first duration according to the target expectation and the mean square error; and if the target temperature is greater than or equal to a second preset temperature, early warning is carried out on a driver of the waste liquid transport vehicle.
Furthermore, when the waste liquid contains the components which are easy to explode, in order to prevent the waste liquid transportation vehicle from generating safety accidents due to the temperature, the safety early warning device can detect the temperature in the tank body in real time so as to prevent the damage or even explosion accidents caused by the overhigh temperature in the tank body.
Specifically, the safety pre-warning device may store in advance the highest temperature of each component that may explode, and determine the value of the preset temperature according to the component of the transportation waste liquid at this time. After the second temperatures in the tank body periodically collected in the transportation process are mapped into a coordinate system, connecting coordinate points of each second temperature to obtain a temperature fitting curve of the tank body in the transportation process. And then calculating target expectation and target variance of the temperature fitting curve, and analyzing the trend of the temperature change in the tank body through the target expectation and target variance so as to estimate the target temperature possibly reached in the tank body after the first time period. And then comparing the target temperature with the highest temperature divided by the target, namely comparing the target temperature with a preset temperature, if the target temperature is larger than the preset temperature, the temperature after the first time period is indicated to possibly cause the damage or explosion of the tank body, and the early warning is needed to be carried out to the driver so as to reduce the temperature in the tank body.
Illustratively, the method further comprises: and when the speed of the waste liquid transport vehicle is greater than a preset speed, periodically broadcasting the first information of the waste liquid transport vehicle, and sending the first information to a management department of the target area for early warning.
In a specific implementation, when the waste liquid transport vehicle leaks and the waste liquid transport vehicle is still running, in order to avoid injury to personnel on other vehicles on a running path, the safety early warning device can periodically broadcast the vehicle information of the waste liquid driving vehicle so as to enable personnel or surrounding personnel on other vehicles to be far away from or prevented as soon as possible, and can send early warning information to a management department managing the running path, so that the management department can timely evacuate the driving vehicles and personnel on the running path and timely treat the leaked waste liquid.
