Hereinafter, the operations of the server 110 and the vehicle terminal 120 will be described in more detail.

Figure 3 is a flowchart showing the operation of an illegal dumping detection system according to an embodiment of the present disclosure.

As already described, the illegal dumping detection system may include a vehicle terminal 120 mounted on the vehicle and a server 110 located remotely from the vehicle.

The server 110 may perform step 310 of accumulating and acquiring weight data about the weight of waste loaded on the vehicle in real time based on the weight sensor included in the vehicle terminal 120. More specifically, the vehicle terminal 120 can acquire weight data in real time based on the weight sensor included in the sensor unit. The vehicle terminal 120 may acquire the weight value in a predetermined first cycle. The weight data may include at least one weight value acquired in a predetermined first cycle. Weight data may include weight values over time. Weight data may include the weight of waste according to loading, operation, and unloading of waste. Weight data may include multiple weight values. Refer to FIG. 4 to explain the obtained weight data.

Figure 4 is a diagram showing weight data according to an embodiment of the present disclosure.

Weight data may include weight values over time. Figure 4 is a graphical representation of weight data.

If the vehicle terminal 120 is turned off in section 1 (410), weight data may not be obtained. That is, when the vehicle terminal 120 is turned off, the weight value may be 0. However, it is not limited to this, and when the vehicle terminal 120 is turned off, the weight value may maintain the previous value. The previous value may be one of the weight values obtained in the first cycle.

In section 2 (420), the vehicle can move to the discharge point to collect the waste. The vehicle terminal 120 is turned on, and weight data is acquired by the sensor unit, so that a weight value different from that in section 1 (410) can be measured in section 2 (420).

In section 3 (430), the vehicle can arrive at the discharge point and collect the waste. Weight values can increase significantly depending on waste collection.

In section 4 (440), the vehicle can move to another discharge source. In section 5 (450), the vehicle can arrive at another discharge point to collect the waste. In section 6 (460), the vehicle can move to the treatment plant. In section 470, the vehicle can arrive at the treatment plant and unload the waste. In section 480, the vehicle can move to the parking lot. If the vehicle's engine is turned off in section 490, the weight value included in the weight data may be 0. However, it is not limited to this, and when the vehicle terminal 120 is turned off, the weight value may maintain the previous value.

Referring again to FIG. 3, the vehicle terminal 120 may transmit weight data to the server 110 through the communication unit. The vehicle terminal 120 can transmit weight data to the server 110 in real time. However, it is not limited to this, and the vehicle terminal 120 may transmit weight data to the server 110 at a predetermined second cycle. The second period may be longer than or equal to the first period.

The server 110 may perform step 320 of determining the critical weight difference. The critical weight difference may be a threshold for determining that waste has been illegally dumped. The critical weight difference may be a predetermined value. The critical weight difference can be a positive real value. However, it is not limited to this and may be a value received from the manager terminal 150. Alternatively, at least one of the server 110 and the vehicle terminal 120 may determine the critical weight difference based on the value measured by the sensor unit. The method for determining the critical weight difference will be explained later.

After the vehicle departs from the discharge location, the server 110 may perform a step 330 of obtaining an initial weight value related to the weight of the waste loaded on the vehicle based on the weight data.

Step 330 will be described in detail with reference to FIG. 5.

Figure 5 is a flowchart showing the operation of the illegal dumping detection system 100 according to an embodiment of the present disclosure.

The step 330 of acquiring the initial weight value may include the following processes.

The server 110 may perform the following process to determine whether the vehicle has departed from the discharge location based on the vehicle's location information. The server 110 may perform step 510 of acquiring vehicle location data indicating the location of the vehicle from the location sensor included in the vehicle terminal 120. More specifically, the vehicle terminal 120 can obtain location information of the vehicle based on the sensor unit. The sensor unit may include a position sensor. The vehicle terminal 120 can obtain vehicle location information over time as vehicle location data. That is, vehicle location data may include at least one location information of the vehicle over time. The location information of the vehicle may include at least one of GPS and GLONASS location information. The vehicle terminal 120 may transmit vehicle location data to the server 110.

If the vehicle location data differs from the predetermined discharge location information by more than a critical distance, step 520 may be performed to determine that the vehicle is transporting waste. More specifically, the server 110 may store discharge location information. The server 110 may determine that the vehicle is transporting waste when the distance of the vehicle's location information included in the discharge location information and vehicle location data exceeds a predetermined threshold distance. That is, the server 110 may determine that the vehicle has departed from the discharge location.

More specifically, if the distance of the vehicle's location information included in the discharge location information and the vehicle location data exceeds the predetermined threshold distance and the predetermined first critical position maintenance time has elapsed, the server 110 determines that the vehicle is discharged from the discharge location. You can decide that you have started. Here, the critical distance can be between 5m and 20m. Additionally, the first critical position holding time may be 25 seconds or more and 1 minute or less.

The server 110 may perform a step 530 of obtaining the average value of the discharge destination weight data acquired during the first critical weight maintenance time within the discharge destination among the weight data as the first discharge destination weight average value. For example, the server 110 may obtain the average of at least one weight value obtained during the first critical weight maintenance time immediately before the vehicle leaves the discharge location as the first discharge location weight average value. The first critical weight maintenance time may be determined in advance and may be 3 minutes or more and 10 minutes or less. The server 110 may use weight data obtained within the discharge source to obtain the first discharge destination weight average value. Here, the weight data acquired within the discharge source may be a subset of the total weight data. Weight data acquired within the discharge source may mean weight data acquired before the vehicle is determined to be transporting waste in step 520. In addition, here, the weight data acquired within the discharge source may mean weight data obtained before the vehicle is determined to be transporting waste in step 520 and obtained when the vehicle is not moving. Whether the vehicle is moving can be obtained by the sensor unit included in the vehicle terminal 120.

The server 110 may perform a step 540 of obtaining the average value of the transport weight data obtained during the second critical weight maintenance time after departure from the discharge destination among the weight data as the second discharge destination weight average value. For example, the server 110 may obtain the average of at least one weight value obtained during the second critical weight maintenance time immediately after the vehicle leaves the discharge location as the second discharge location weight average value. The second critical weight maintenance time may be determined in advance and may be 3 minutes or more and 10 minutes or less. For example, the second critical weight maintenance time may be 5 minutes. The second critical weight maintenance time may be greater than the first critical weight maintenance time. The second critical weight maintenance time may be applied to transportation weight data when the vehicle is moving, and the first critical weight maintenance time may be applied to weight data when the vehicle is stationary. In general, weight data is accurately measured when the vehicle is stopped, so the time and processor processing resources used to obtain the first discharge destination weight average value can be saved by making the first critical weight maintenance time shorter than the second critical weight maintenance time. there is. Additionally, by lengthening the second critical weight maintenance time, the second discharge destination weight average value can be accurately obtained.

The server 110 may use the transportation weight data to obtain the second discharge destination weight average value. Here, transport weight data may mean weight data obtained after it is determined in step 520 that the vehicle is transporting waste. In other words, transportation weight data may be a subset of total weight data. In addition, here, the transport weight data is obtained after it is determined in step 520 that the vehicle is transporting waste, and may mean weight data acquired while the vehicle is moving. Whether the vehicle is moving can be obtained by the sensor unit included in the vehicle terminal 120.

If the absolute value of the difference between the first discharge destination weight average value and the second discharge destination weight average value is less than or equal to the critical weight difference, the server 110 performs step 550 of determining the first discharge destination weight average value as the initial weight value. can do. The critical weight difference may be the value obtained in step 330.

In addition, the server 110 determines the second discharge destination weight average value as the initial weight value when the absolute value of the difference between the first discharge destination weight average value and the second discharge destination weight average value exceeds the critical weight difference (step 560). can be performed.

Since the server 110 determines the initial weight value through steps 550 and 560, the server 110 can accurately obtain the initial weight value. This is because, if there is no significant difference between the first discharge destination weight average value and the second discharge destination weight average value, the first discharge destination weight average value measured when stopped is used, and if there is a large difference, the most recently measured second discharge destination weight average value is used. This is because the average weight value is used. In general, the average weight of the first discharge point measured when stopped is accurate, but if there is a large difference, there may be abnormal signs such as illegal disposal after departure from the discharge point, so the average weight of the second discharge point after departure is used. .

Referring again to FIG. 3, when the vehicle arrives at the treatment plant, the server 110 may perform step 340 of obtaining a final weight value related to the weight of the waste loaded on the vehicle based on the weight data.

Reference is made to Figure 6 to explain step 340.

Figure 6 is a flowchart showing the operation of the illegal dumping detection system 100 according to an embodiment of the present disclosure.

The server 110 may perform the following process to perform step 340 of obtaining the final weight value.

The server 110 may perform step 610 of acquiring vehicle location data indicating the location of the vehicle from the location sensor included in the vehicle terminal 120. Step 610 may be the same as step 510. Therefore, redundant explanations are omitted.

If the vehicle location data differs from the predetermined treatment plant location information by a threshold distance or less, the server 110 may perform step 620 of determining that the vehicle has arrived at the treatment plant. More specifically, the server 110 may store processing plant location information. The server 110 may determine that the vehicle has arrived at the treatment plant when the distance of the vehicle's location information included in the treatment plant location information and vehicle location data is less than or equal to a predetermined threshold distance. That is, the server 110 may determine that the vehicle has arrived at the treatment plant.

More specifically, the server 110 determines that the vehicle has arrived at the processing plant when the distance of the vehicle's location information included in the processing plant location information and vehicle location data is less than a predetermined threshold distance and more than a predetermined second critical position maintenance time has passed. You can. Here, the critical distance can be between 5m and 20m. Additionally, the second critical position holding time may be 25 seconds or more and 1 minute or less. The first critical position holding time may be the same as the second critical position holding time. However, it is not limited to this, and the second critical position holding time may be shorter than the first critical position holding time. In this way, even if the second critical position holding time is shorter than the first critical position holding time, it can be accurately determined that the vehicle has arrived at the treatment plant. This is because when the vehicle is stopped after arriving at the treatment plant, the location information of the vehicle is more accurate than the location information of the vehicle when it is moving. Therefore, by making the second critical position holding time smaller than the first critical position holding time, the time and processor processing resources used to determine that the vehicle has arrived at the treatment plant can be saved. Additionally, by lengthening the first critical position holding time, it is possible to accurately determine whether the device has left the discharge source.

The server 110 may perform a step 630 of obtaining the average value of the transportation weight data obtained during the second critical weight maintenance time immediately before arriving at the treatment plant among the weight data as the first treatment plant weight average value. Since the second critical weight maintenance time has been described together with step 540, redundant description will be omitted. The transport weight data of step 630 may be data acquired at a different time than the transport weight data of step 540. The transport weight data of step 630 may be a subset of the total weight data. Here, transportation weight data may mean weight data obtained before it is determined in step 620 that the vehicle has arrived at the treatment plant. In addition, here, transportation weight data may mean weight data obtained before it is determined in step 620 that the vehicle has arrived at the treatment plant and obtained while the vehicle is moving.

The server 110 may perform a step 640 of obtaining the average value of the weight data of the treatment plant obtained during the first critical weight maintenance time after arriving at the treatment plant among the weight data as the second treatment plant weight average value. Since the first critical weight maintenance time has been described in step 530, redundant description will be omitted. Here, the treatment plant weight data may mean weight data obtained after it is determined that the vehicle has arrived at the treatment plant in step 620. The side treatment plant weight data may be a subset of the total weight data. In addition, here, the treatment plant weight data is obtained after it is determined in step 620 that the vehicle has arrived at the treatment plant, and may mean weight data obtained when the vehicle is not moving. Whether the vehicle is moving can be obtained by the sensor unit included in the vehicle terminal 120.

If the absolute value of the difference between the first treatment plant weight average value and the second treatment plant weight average value is less than or equal to the critical weight difference, the server 110 may perform step 650 of determining the second treatment plant weight average value as the final weight value. . In addition, when the absolute value of the difference between the first treatment plant weight average value and the second treatment plant weight average value exceeds the critical weight difference, a step 660 of determining the first treatment plant weight average value as the final weight value can be performed.

Since the server 110 determines the final weight value through steps 650 and 660, the server 110 can accurately obtain the final weight value. This is because, if there is no significant difference between the first treatment plant weight average value and the second treatment plant weight average value, the second treatment plant weight average value measured when stopped is used, and if there is a large difference, the recently measured first treatment plant weight average value is used. Because it does. In general, the average weight of the second treatment plant measured when stopped is accurate, but if there is a large difference, there may be abnormal signs such as illegal disposal before arrival, so the average weight of the first treatment plant before arrival is used.

Referring again to FIG. 3, the server 110 may perform step 350 of determining whether to generate an alarm related to illegal disposal based on at least one of weight data, initial weight, and final weight.

The step 350 of determining whether to generate an alarm related to illegal disposal will be described with reference to FIG. 7.

Figure 7 is a flowchart for explaining the operation of an illegal dumping detection system according to an embodiment of the present disclosure.

The step 350 of determining whether to generate an illegal disposal-related alarm may include the following process.

If the vehicle is transporting waste and the transport deduction value obtained by subtracting the initial weight from the transport weight included in the weight data is less than or equal to the negative value of the critical weight difference, the server 110 generates an alarm related to illegal disposal. (710) can be performed. Illegal disposal-related alarms may include the location and time when the transportation offset value is less than or equal to the negative value of the critical weight difference. Therefore, managers can know exactly where and when illegal disposal occurred. Here, the critical weight difference may be a positive real value.

That the vehicle is transporting waste may mean after the vehicle is determined to have departed from the discharge source in step 330 and before the vehicle is determined to have arrived at the treatment plant in step 340. Transport weight values may be included in the weight data. The transport weight value may be included in the transport weight data included in the weight data. The transportation weight may be a weight measured while the vehicle is transporting waste. The initial weight value is obtained in step 330, and since it has already been described, redundant description will be omitted. The transportation deduction value represents the value obtained by subtracting the initial weight value from the transportation weight value. A negative shipping deduction value may mean that the weight of the waste has decreased. In other words, it may mean that illegal disposal has occurred. Additionally, a positive transportation deduction value may mean that the weight of the waste has increased. For example, if it rains, the waste may get wet and increase in weight. If the transportation deduction value is a negative number, an alarm related to illegal disposal may be generated, but a false alarm may occur due to sensor error. Therefore, the illegal dumping detection system 100 can use the critical weight difference.

The critical weight difference can be positive. If the transportation deduction value obtained by subtracting the initial weight from the transportation weight value is less than or equal to the negative value of the critical weight difference, the server 110 may generate an alarm related to illegal disposal. Therefore, it is possible to prevent alarms related to illegal disposal from being incorrectly generated. Therefore, the manager can trust the illegal dumping detection system 100. The critical weight difference may be a predetermined value. The critical weight difference will be explained in detail later.

If the transportation deduction value exceeds the critical weight difference, the server 110 may perform step 720 of generating a details confirmation request alarm. If the transportation deduction value exceeds the critical weight difference, it may indicate that the weight of the waste has increased excessively. This may indicate a cause other than the increase in weight caused by the waste becoming wet. Therefore, managers or vehicle drivers can prevent unexpected accidents by checking whether there is something wrong with the waste.

If the transportation deduction value is greater than the negative value of the critical weight difference and is less than the critical weight difference, the server 110 may determine that the vehicle is in a normal state. Therefore, the server 110 may not output an alarm.

The server 110 may repeatedly perform steps 710 and 720 at a predetermined cycle until the vehicle leaves the discharge source and arrives at the treatment plant. Therefore, the administrator can receive at least one of an illegal disposal-related alarm and a history confirmation request alarm in real time.

When the vehicle arrives from the treatment plant and the final subtracted value obtained by subtracting the initial weight from the final weight is less than or equal to the negative value of the critical weight difference, the server 110 performs a step 730 of generating an alarm related to illegal disposal. can do. The final weight value may be the value obtained in step 340. Additionally, the initial weight value may be the value obtained in step 330. The final deduction value may be the value obtained by subtracting the initial weight value from the final weight value. However, it is not limited to this, and the final deduction may be the value obtained by subtracting the transportation weight from the final weight. Similar to step 710, if the final deduction value in step 730 is less than or equal to the negative value of the critical weight difference, the server 110 may generate an alarm related to illegal disposal.

Additionally, if the final deduction value exceeds the critical weight difference, the server 110 may perform step 740 of generating a details confirmation request alarm. Step 740 may be similar to step 720.

If the final deduction value is greater than the negative value of the critical weight difference and is less than or equal to the critical weight difference, the server 110 may determine that it is in a normal state. Therefore, the server 110 may not output an alarm.

Server 110 may perform steps 730 and 740 once upon arrival at the treatment plant. However, the process is not limited to this, and the server 110 may repeatedly perform steps 730 and 740 at predetermined intervals.

The illegal dumping detection system of the present disclosure detects illegal dumping by generating an alarm related to illegal dumping, which is suspected of illegal dumping, or a detail confirmation request alarm indicating that illegal dumping is not suspected but there are abnormal symptoms, and allowing the manager to monitor the vehicle. You can make sure it never happens. In addition, when a history confirmation request alarm is generated, the administrator can input into the illegal dumping detection system why abnormal signs have occurred, and the illegal dumping detection system uses the input information as big data to implement a more accurate illegal dumping detection system. You can make it happen.

Hereinafter, a method for determining the critical weight difference will be described with reference to FIG. 8.

Figure 8 is a flowchart for explaining the operation of the illegal dumping detection system according to an embodiment of the present disclosure. Figure 9 may show a load index table according to an embodiment of the present disclosure.

Step 320 of determining the critical weight difference in FIG. 3 may include the following process. The server 110 may perform step 810 of acquiring a tire air pressure value based on the tire air pressure sensor included in the vehicle terminal 120. The tire air pressure sensor may be included in the sensor unit.

The server 110 may perform step 820 of determining the maximum load corresponding to the tire air pressure value based on at least one of a predetermined load index table and (Equation 1). The load index table may be as shown in FIG. 9. The server 110 can determine the intermediate maximum load by applying the tire air pressure value to the load index table. The intermediate maximum load is one of the characteristics of the tire and can be determined according to the load index.

The server 110 may determine the maximum load based on Equation 1. Equation 1 is as follows.

(Equation 1): Maximum load = (Tire air pressure value/maximum allowable tire air pressure) * [Medium maximum load according to load index * Number of tires]

Here, the tire air pressure value may be a value obtained in step 810. The maximum allowable tire pressure may be a predetermined value. The maximum allowable tire pressure may be predetermined based on the type of tire. For example, the maximum allowable tire pressure may be determined by the marking on the tire, the automobile manufacturer's marking, or the user's arbitrary setting. The intermediate maximum load according to the load index may be a value obtained based on the load index table. The load index is one of the characteristics of a tire and can be determined in advance based on the type of tire. For example, the load index can be determined by the markings on the tire or the automobile manufacturer's markings. The number of tires may refer to the number of wheels the vehicle is equipped with.

For example, if the tire air pressure value is 30, the maximum allowable tire pressure is 50, the load index is 100, and the number of tires is 4, the server 110 may determine the intermediate maximum load according to the load index to be 800 kg. there is. Additionally, the server 110 can determine the maximum load to be 1920 kg according to (Equation 1).

Equation 1 assumes the same load on each tire. According to various embodiments of the present disclosure, the server 110 may determine the maximum load for each tire. For example, the server 110 may determine the maximum load for each tire based on Equation 2.

(Equation 2): Maximum load for each tire = (tire air pressure value/maximum allowable tire air pressure) * [intermediate maximum load according to load index]

After determining the maximum load for each tire, the server 110 may determine the weighted sum of the maximum loads for each tire as the maximum load.

For example, if a vehicle has N tires, the maximum load can be determined as shown in Equation 3 below.

(Equation 3): Maximum load = W1 * maximum load of the first tire + ... + WN * maximum load of the N tire

Here, the maximum load of the first tire to the maximum load of the Nth tire may be determined to be the same as the maximum load for each tire in Equation 2. W1 to WN may be predetermined values. W1 to WN may be determined by axle distribution ratio, season, temperature, road surface, or driving habits. W1+ ... + WN can be equal to N. However, it is not limited to this.

The server 110 may perform step 830 of determining the critical weight difference by multiplying the maximum load by a predetermined error rate. The error rate may be a predetermined value. The error rate may be between 3% and 10%. More specifically, the error rate may be 5%. If the maximum load is 1920 kg and the error rate is 5%, the critical weight difference can be 96 kg.

By determining the critical weight difference as above, illegal dumping detection can be standardized depending on the vehicle and tire. Therefore, differences in illegal dumping detection depending on vehicles and tires may be small, and user complaints due to differences in illegal dumping detection may be reduced. Therefore, the reliability of the illegal dumping detection system can increase.

Below, the operation of the illegal dumping detection system 100 when it is in an abnormal state will be described with reference to FIG. 10. An abnormal state of the illegal dumping detection system 100 may mean that communication between the server 110 and the vehicle terminal 120 is not possible, it is raining or snowing, or it is stopping while raining or snowing. Additionally, an abnormal condition may be a situation in which the weight sensor does not operate properly because the vehicle is going downhill or uphill.

Figure 10 is a flowchart for explaining the operation of the illegal dumping detection system 100 according to an embodiment of the present disclosure.

The illegal dumping detection system 100 may perform a step (1010) of acquiring an average weight just before abnormality based on weight data before entering a predetermined danger zone.

The risk section may include at least one of a communication blackout section and a gradient section. The communication interruption section may mean a section in which communication between the vehicle terminal 120 and the server 110 is cut off. The slope section may be a section where the weight sensor cannot function properly due to the steep uphill and downhill slopes. The reason why the weight sensor does not work properly when going uphill or downhill is that the weight sensor measures the weight in a direction perpendicular to the ground, but when going uphill or downhill, the waste is pushed to the front or back of the vehicle, so the weight of the waste is in the direction perpendicular to the ground. This is because less force is applied. The average weight just prior to abnormality may be a value based on weight data measured in normal conditions before the risk section.

The illegal dumping detection system 100 may perform a step 1020 of acquiring an average weight immediately after abnormality based on weight data after escaping from the danger zone. The average weight immediately after the abnormality may be based on at least one of weight data measured in a normal state after the risk interval and weight data measured within the risk interval.

If the risk section deduction value obtained by subtracting the weight average value immediately before abnormality from the weight average value immediately after abnormality is less than or equal to the negative value of the critical weight difference, the server 110 may perform step 1030 of generating an alarm related to illegal disposal. Here, the critical weight difference may be a positive value. Step 1030 may be similar to steps 710 and 730. Step 1030 can be performed once after escaping the danger section. However, the process is not limited to this, and the server 110 may repeatedly perform steps 1010 to 1030 at predetermined intervals. The illegal disposal-related alarm may include at least one of the location of the entrance to the dangerous section, the location of the exit, the path between the location of the entry and the location of the exit, and the length of the dangerous section.

Steps 1010 to 1030 can be performed in a state where communication is interrupted, so the vehicle terminal 120 can perform them instead of the server 110. However, it is not limited to this, and the vehicle terminal 120 can accumulate and store weight data while communication is interrupted and then transmit the weight data to the server 110 after communication is resumed, and the server 110 After receiving the weight data, steps 1010 to 1030 can be performed.

According to an embodiment of the present disclosure, the step 1010 of acquiring the average weight just before abnormality may include the following process. When the vehicle enters the communication loss section, a step of acquiring the communication loss section can be performed based on the map data of the vehicle terminal 120. If communication between the server 110 and the vehicle terminal 120 is interrupted, the vehicle terminal 120 cannot send the measured weight data to the server 110. Therefore, when communication between the server 110 and the vehicle terminal 120 is interrupted, the vehicle terminal 120 can perform steps 1010 to 1030 of FIG. 10. The vehicle terminal 120 can obtain map data stored in memory. The vehicle terminal 120 can obtain the communication loss section included in the map data.

A communication blackout section may mean a section deep in the mountains, on an island, or in a tunnel. The vehicle terminal 120 may store map data in advance. Map data may include sections where communication is lost. Additionally, the vehicle terminal 120 can obtain a communication loss section based on map data. The communication interruption section may include at least one of the location of the entryway, the location of the exit, the path between the location of the entryway and the location of the exit, and the length of the communication interruption section. If the vehicle's location information and the entrance location match, the vehicle terminal 120 may determine that the vehicle has entered the communication loss section. Additionally, when communication with the server 110 is lost, the vehicle terminal 120 may determine that it has entered a communication interruption section.

The vehicle terminal 120 may perform a step of obtaining a first reference time, which is when the vehicle reaches a location before a predetermined critical remaining distance from the location of the entrance to the communication loss section. The vehicle terminal 120 may store location information and time of the vehicle correspondingly. The vehicle terminal 120 may obtain the time when the vehicle reaches a position before the predetermined critical remaining distance from the entrance location based on the map data as the first reference time. The vehicle terminal 120 and the server 110 may have communicated normally at the first reference time. The predetermined critical remaining distance may be a value greater than 0.

According to various embodiments of the present disclosure, the vehicle terminal 120 may determine the time before the critical remaining time from the time the vehicle enters the entrance location as the first reference time.

The vehicle terminal 120 may perform a step of obtaining the average value of the weight data just before abnormality acquired during the second critical weight maintenance time in the past from the first reference time among the weight data as the average weight value just before abnormality. The second critical weight maintenance time is configured to measure the average value based on transportation weight data measured while the vehicle is moving. Refer to FIG. 11 to explain the second critical weight holding time.

Figure 11 is a diagram for explaining the operation of an illegal dumping detection system according to an embodiment of the present disclosure.

Referring to (a) of FIG. 11, the illegal dumping detection system 100 can acquire weight data. Figure 11 (a) may be a graph showing weight data of the illegal dumping detection system 100. In (a) of FIG. 11, the horizontal axis may be time and the vertical axis may be weight values. Weight data can be acquired continuously over time. However, due to the inaccuracy of the weight sensor included in the vehicle terminal 120, there may be a section where the weight data changes significantly, such as area 1110. Sections where weight data changes significantly may be caused by vibration that occurs when the vehicle moves.

The illegal dumping detection system 100 can prevent weight data from being significantly changed based on the second critical weight maintenance time. For example, the illegal dumping detection system 100 may determine the weight value at the current time as the average of weight data measured during the second critical weight maintenance time from the current time to the past. In addition, the illegal dumping detection system 100 calculates the weight value at the current time as the average of the weight data measured from (current time - second critical weight maintenance time/n) to (current time + second critical weight maintenance time/m). can be decided. Here (1/n + 1/m) may be 1. n and m may be real numbers of predetermined quantities.

Referring to (b) of FIG. 11, it can be seen that the weight data of area 1120 does not change significantly. Figure 11 (c) is for a case where the second critical weight maintenance time is greater than the critical weight maintenance time in Figure 11 (b). According to (c) of FIG. 11, area 1130 may have more uniform weight data than area 1120. However, like area 1140, it may have a delayed response to changes in weight data. If there is a delayed response, the illegal dumping detection system 100 may not be able to generate an alarm in real time. Therefore, an appropriate second critical weight holding time that is neither too large nor too small needs to be used. The second critical weight maintenance time can be selected from 1 minute, 5 minutes, and 10 minutes.

Referring again to FIG. 10, the step 1020 of acquiring the average weight value immediately after the abnormality may include the following steps.

The illegal dumping detection system 100 may perform a step of determining the time when the vehicle exits the communication blackout section as the second reference time. The second reference time may be a time in the future than the first reference time. The second reference time may refer to the time when communication between the vehicle terminal 120 and the server 110 is resumed. The second reference time may be the time when the vehicle's location information arrives at the exit location. The second reference time may mean the time at which the distance the vehicle has moved from the location of the entrance coincides with the length of the communication interruption section. Here, the distance traveled by the vehicle can be obtained based on the moving distance measurement sensor included in the vehicle terminal 120.

The illegal dumping detection system 100 may perform a step of obtaining the average value of the weight data immediately after the abnormality obtained during the second critical weight maintenance time in the past from the second reference time among the weight data as the average weight value immediately after the abnormality. If the risk section deduction value obtained by subtracting the weight average value immediately before abnormality from the weight average value immediately after abnormality is less than or equal to the negative value of the critical weight difference, the illegal dumping detection system 100 performs the step 1030 of generating an alarm related to illegal disposal. You can. The illegal disposal-related alarm may include at least one of the location of the entrance to the communication interruption section, the location of the exit exit, the path between the location of the entrance and the location of the exit, and the length of the communication interruption section. The illegal disposal-related alarm may include at least one of the alarm creation time, the time the vehicle entered the entrance, and the time the vehicle exited the exit door. Therefore, managers can know where and when illegal disposal occurred. Since the driver can see that an alarm related to illegal disposal is generated, he or she can be careful to prevent illegal disposal.

According to various embodiments of the present disclosure, the step 1010 of acquiring the average weight just before abnormality may include the following steps.

The illegal dumping detection system 100 may perform a step of obtaining the time when communication between the vehicle terminal 120 and the server 110 was interrupted as a first reference time. In the previous embodiment, the vehicle terminal 120 determined the time when the vehicle reached the position before the predetermined critical remaining distance from the location of the entrance to the communication interruption section as the first reference time, so to determine the first reference time, data had to be obtained or calculated based on the data. However, in various embodiments, the illegal dumping detection system 100 determines the time when communication between the vehicle terminal 120 and the server 110 was cut off as the first reference time, so that the first reference time can be quickly acquired.

The illegal dumping detection system 100 may perform a step of obtaining the average value of the weight data just prior to abnormality acquired during the second critical weight maintenance time in the past from the first reference time among the weight data as the average value of the weight immediately prior to abnormality.

Additionally, the illegal dumping detection system 100 may not determine the first reference time. When communication between the vehicle terminal 120 and the server 110 is interrupted, the illegal dumping detection system 100 determines the abnormal immediate weight based on the abnormal immediate weight data acquired during the second critical weight maintenance time in the past from the time of disconnection. The average value can also be obtained.

Additionally, the step 1020 of acquiring the average weight value immediately after the abnormality may include the following steps. The illegal dumping detection system 100 may perform a step of determining the time when communication between the vehicle terminal and the server is reconnected as the second reference time. Unlike the previous embodiment, the illegal dumping detection system 100 can quickly acquire the second reference time.

The illegal dumping detection system 100 may perform a step of obtaining the average value of the weight data immediately after the abnormality obtained during the second critical weight maintenance time in the past from the second reference time among the weight data as the average weight value immediately after the abnormality. If the risk section deduction value obtained by subtracting the weight average value immediately before abnormality from the weight average value immediately after abnormality is less than or equal to the negative value of the critical weight difference, the server 110 may perform step 1030 of generating an alarm related to illegal disposal. The illegal disposal-related alarm may include at least one of the location of the entrance to the communication interruption section, the location of the exit exit, the path between the location of the entrance and the location of the exit, and the length of the communication interruption section. The illegal disposal-related alarm may include at least one of the alarm creation time, the time the vehicle entered the entrance, and the time the vehicle exited the exit door. Therefore, managers can know where and when illegal disposal occurred. Drivers can be aware that an alarm related to illegal disposal is generated, so they can be careful to prevent illegal disposal.

According to various embodiments of the present disclosure, the illegal dumping detection system 100 may perform the following operations when a vehicle enters a gradient section such as a downhill or uphill road. For example, the step 1010 of acquiring the average weight just before abnormality may include the following steps.

When the vehicle enters a sloping section, the vehicle terminal 120 may perform a step of acquiring the sloping section based on map data. A gradient section can mean an uphill or downhill section. A slope section may refer to a section where the slope of the road is more than a predetermined critical angle with respect to the horizontal plane. Since the vehicle's waste is pushed to the front or rear on a gradient section, the weight sensor that measures the weight in the direction perpendicular to the ground may not properly determine the weight of the waste.

Map data may include gradient sections. Additionally, the vehicle terminal 120 can obtain a gradient section based on map data. The gradient section may include at least one of the location of the entryway, the location of the exit, the path between the location of the entryway and the location of the exit, and the length of the gradient section. If the vehicle's location information and the entrance location match, the vehicle terminal 120 may determine that the vehicle has entered the gradient section. Additionally, the vehicle terminal 120 can obtain the vehicle angle at which the vehicle is tilted from the horizontal plane based on the sensor unit. If the vehicle angle is greater than or equal to the critical angle, the vehicle terminal 120 may determine that the vehicle has entered the gradient section.

The illegal dumping detection system 100 may perform a step of obtaining a first reference time, which is when the vehicle reaches a position before a predetermined critical remaining distance from the location of the entrance to the gradient section. The vehicle terminal 120 may store location information and time of the vehicle correspondingly. The vehicle terminal 120 may obtain the time when the vehicle reaches a position before the predetermined critical remaining distance from the entrance location based on the map data as the first reference time.

According to various embodiments of the present disclosure, the vehicle terminal 120 may determine the time before the critical remaining time from the time the vehicle enters the entrance location as the first reference time.

The illegal dumping detection system 100 may perform a step of obtaining the average value of the weight data just prior to abnormality acquired during the second critical weight maintenance time in the past from the first reference time among the weight data as the average value of the weight immediately prior to abnormality. The second critical weight maintenance time is configured to measure the average value based on transportation weight data measured while the vehicle is moving. Since the second critical weight maintenance time has been described with reference to FIG. 11, redundant description will be omitted.

The step 1020 of acquiring the average weight value immediately after the abnormality may further include the following steps. The illegal dumping detection system 100 may perform a step of determining the time when the vehicle exits the grade section as the second reference time. The second reference time may be a time in the future than the first reference time. The second reference time may mean the time when the vehicle angle becomes less than the critical angle. The second reference time may be the time when the vehicle's location information arrives at the location of the exit. The second reference time may mean the time at which the distance the vehicle has moved from the location of the entrance coincides with the length of the gradient section. Here, the distance traveled by the vehicle can be obtained based on the moving distance measurement sensor included in the vehicle terminal 120.

The illegal dumping detection system 100 may perform a step of obtaining the average value of the weight data immediately after the abnormality obtained during the second critical weight maintenance time in the past from the second reference time among the weight data as the average weight value immediately after the abnormality. If the risk section deduction value obtained by subtracting the weight average value immediately before abnormality from the weight average value immediately after abnormality is less than or equal to the negative value of the critical weight difference, the illegal dumping detection system 100 performs the step 1030 of generating an alarm related to illegal disposal. You can. The illegal disposal-related alarm may include at least one of the location of the entrance to the gradient section, the location of the exit, the path between the location of the entrance and the location of the exit, and the length of the communication interruption section. The illegal disposal-related alarm may include at least one of the alarm creation time, the time the vehicle entered the entrance, and the time the vehicle exited the exit door. Therefore, managers can know where and when illegal disposal occurred. Since the driver can see that an alarm related to illegal disposal is generated, he or she can be careful to prevent illegal disposal. The illegal dumping detection system 100 of the present disclosure can operate without error even in gradient sections. Therefore, users can trust the illegal dumping detection system 100.

Below, a scenario when a vehicle passes through a snowy or rainy area will be described.

Figure 12 is a flowchart for explaining the operation of the illegal dumping detection system 100 according to an embodiment of the present disclosure.

The step 350 of determining whether to generate an illegal disposal-related alarm may include the following steps.

When the vehicle is transporting waste and the precipitation sensor included in the vehicle terminal 120 indicates that it is raining or snowing, the server 110 performs a step 1210 of acquiring the first weight change rate based on the weight data. It can be done.

Since the process of determining whether a vehicle is transporting waste has already been described, redundant explanation will be omitted.

The sensor unit included in the vehicle terminal 120 may include a precipitation sensor. Precipitation sensors can detect that it is raining or snowing. The vehicle terminal 120 may transmit information about whether it is raining or snowing detected by the precipitation sensor to the server 110. The server 110 or the vehicle terminal 120 may determine whether it is raining or snowing based on information about whether it is raining or snowing.

However, it is not limited to this. The vehicle terminal 120 can obtain location information of the vehicle. The server 110 may obtain information about whether it is raining or snowing in a location corresponding to the location information of the vehicle from an external server. The server 110 or the vehicle terminal 120 can obtain information about whether it is raining or snowing from an external server. The external server may be a weather information providing server.

The step 1210 of obtaining the first weight change rate may include the following process. The first weight change rate may be obtained based on weight data. The server 110 may perform a step of acquiring the a-th time when the precipitation sensor indicates that it is raining or snowing. Here, a may be a natural number. Time a may refer to the time of day in a predetermined period after indicating that it is raining or snowing.

The server 110 may perform a step of obtaining the average value of the a-th precipitation weight data obtained during the second critical weight maintenance time in the past from the a-th time among the weight data as the a-th precipitation weight average value. The precipitation weight average value a may mean the average of a plurality of weight values obtained during the second critical weight maintenance time in the past from time a. However, it is not limited to this, and the server 110 measures the precipitation weight average value from (time a - second critical weight maintenance time/n) to (time a + second critical weight maintenance time/m). It can be determined by averaging the weight data. Here (1/n + 1/m) may be 1. n and m may be real numbers of predetermined quantities.

The server 110 may perform a step of acquiring the a+1-th time after the detection period from the a-th time. The server 110 may perform a step of obtaining the average value of the a+1 precipitation weight data obtained during the second critical weight maintenance time in the past from the a+1 time among the weight data as the a+1 precipitation weight average value. there is. The a+1 precipitation weight average value may mean the average of a plurality of weight values obtained during the second critical weight maintenance time in the past from the a+1 time. However, it is not limited to this, and the server 110 calculates the a+1 precipitation weight average value from (a+1 time - 2nd critical weight maintenance time/n) to (a+1 time + 2nd critical weight maintenance time). /m) can be determined as the average of the weight data measured.

The server 110 may perform a step of determining the value obtained by subtracting the a+1 precipitation weight average value from the ath precipitation weight average value as the first weight change rate. However, it is not limited to this, and the server 110 may obtain the first weight change rate based on the following equation.

The first weight change rate = (the a+1 precipitation weight average value - the a precipitation weight average value)/(the a+1 time - the a time)

The server 110 may perform step 1220 of acquiring the second weight change rate after a predetermined detection period of the first weight change rate. The second weight change rate can be obtained in the same way as the first weight change rate.

The second weight change rate may be obtained based on weight data. For example, the server 110 may obtain the b-th precipitation weight average value at the b-th time and the b+1-th precipitation weight average value at the b+1 time based on the weight data. Here b can be a natural number.

The b-th time may mean a time of day in a predetermined period after indicating that it is raining or snowing. The b-th time may be a time after the a-th time. The b-th time may be a time after a predetermined detection period from the a-th time.

The b+1th time may be a time after a predetermined period from the bth time. The b+1th time may be the ath time, the a+1th time, and the time after the bth time. The b+1 time may be a time after a predetermined detection period from the a+1 time.

The b-th precipitation weight average may mean the average of a plurality of weight values obtained during the second critical weight maintenance time in the past from the b-th time. However, it is not limited to this, and the server 110 measures the b precipitation weight average value from (b time - 2nd critical weight maintenance time/n) to (b time + 2nd critical weight maintenance time/m). It can be determined by averaging the weight data. Here (1/n + 1/m) may be 1. n and m may be real numbers of predetermined quantities.

The b+1 precipitation weight average value may mean the average of a plurality of weight values obtained during the second critical weight maintenance time in the past from the b+1 time. However, it is not limited to this, and the server 110 calculates the b+1 precipitation weight average value from (b+1 time - 2nd critical weight maintenance time/n) to (b+1 time + 2nd critical weight maintenance time). /m) can be determined as the average of the weight data measured.

The server 110 may perform a step of determining a value obtained by subtracting the b-th precipitation weight average value from the b+1 precipitation weight average value as the second weight change rate. However, it is not limited to this, and the server 110 may obtain the second weight change rate based on the following equation.

The 2nd weight change rate = (the b+1 precipitation weight average value - the b precipitation weight average value)/(the b+1 time - the b time)

If the second weight change rate and the first weight change rate are negative numbers, the server 110 may perform step 1230 of generating an illegal disposal-related alarm. If at least one of the second weight change rate and the first weight change rate is a positive number or 0, the server 110 may determine that the vehicle is in a normal state. Therefore, the server 110 may not output an alarm. When it rains or snows, the weight should increase because the waste gets wet. However, if the first and second weight change rates are negative, it means that the weight is decreasing, which can be seen as a sign of abnormality. Therefore, the illegal dumping detection system 100 of the present disclosure can accurately detect illegal dumping even in rainy weather.

According to the illegal dumping detection system 100 of the present disclosure, when the second weight change rate and the first weight change rate are 0, the server 110 multiplies the detection period by the predetermined number of detections from the time of acquiring the second weight change rate. The step of obtaining the third weight change rate after time can be performed.

Here, the case where the second weight change rate and the first weight change rate are 0 may mean that the second weight change rate and the first weight change rate are within a predetermined critical range. The critical range includes 0 and may be a range formed near 0.

The number of detections may be a natural number including 0. The third weight change rate may be the same as the second weight change rate. Additionally, the third weight change rate may be a weight change rate obtained at or after the time the second weight change rate is acquired. Since the process of obtaining the third weight change rate is the same as the process of obtaining the first weight change rate and the second weight change rate, redundant explanations will be omitted.

If the third weight change rate is not 0, the server 110 may perform the step of generating an illegal disposal-related alarm. That the first weight change rate and the second weight change rate are 0 may indicate that the waste is sufficiently wet from rain or snow and there is no change in weight. At this time, the fact that the third weight change rate is not 0 may indicate that there is an abnormality.

According to various embodiments of the present disclosure, when the third weight change rate is a negative number, the server 110 may generate an alarm related to illegal disposal. This is because illegal disposal occurs when waste is reduced from vehicles.

In addition, according to various embodiments of the present disclosure, the third weight change rate is a negative number, and the rain deduction value is obtained by subtracting the average weight value at the time of acquiring the second weight change rate from the transportation weight value at the time of obtaining the third weight change rate. If the critical weight difference is less than or equal to the negative value, an alarm related to illegal disposal can be generated. Here, the average weight value at the time of acquiring the second weight change rate may be one of the b th average precipitation weight value and the b + 1 th average precipitation weight value described above.

In this way, even when the waste is sufficiently wet due to rain or snow, the illegal dumping detection system 100 of the present disclosure can normally detect illegal dumping.

The illegal dumping detection system 100 of the present disclosure can further perform the following processes.

The server 110 may perform a step of determining the time when the precipitation sensor indicates that it is raining or snowing and then indicating that it is not raining or snowing as the third reference time. If it starts not raining or snowing, there may be more moisture leaving the waste than entering it. The vehicle terminal 120 may indicate that it is raining or snowing using a precipitation sensor, and then obtain a third reference time indicating that it is not raining or snowing. The vehicle terminal 120 may transmit the third reference time to the server 110. However, it is not limited to this, and the server 110 receives weather information corresponding to the vehicle's location information from an external server, indicates that it is raining or snowing, and then changes to a third reference time indicating that it is not raining or snowing. can be obtained.

The server 110 may perform a step of obtaining the average value of the third precipitation weight data acquired during the second critical weight maintenance time in the past from the third reference time among the weight data as the third precipitation weight average value. The third precipitation weight average may be a value related to the weight data of the waste when it was raining or snowing.

If the precipitation deduction value obtained by subtracting the third precipitation weight average value from the weight value at the time after the third reference time among the weight data is less than or equal to the negative value of the critical weight difference, the server 110 generates an alarm related to illegal disposal. You can follow the steps. The critical weight difference may be a value greater than the moisture weight of the waste. If there is no rain or snow, the moisture in the waste inevitably decreases. However, if the weight of the waste decreases excessively, it may be determined that the moisture has not disappeared and that there are signs of illegal disposal. Illegal disposal-related alarms may include the alarm creation time and the location where the alarm was generated. Therefore, managers can easily find out the location and time of illegal disposal.

The server 110 can generate an alarm related to illegal disposal even when the vehicle's gear stick is positioned in “N” or “P”. This is because it is a point that clearly indicates that the vehicle has stopped. Of course, the manager will check whether there has been illegal disposal based on the illegal disposal-related alarm, and as a result of the confirmation, it can be determined that there is no illegal disposal and transmit it to the server 110.

According to the illegal dumping detection system 100 according to an embodiment of the present disclosure, when the precipitation sensor indicates that it is raining or snowing and then indicates that it is not raining or snowing, the server 110 is based on the weight data. Thus, the step of obtaining the fourth weight change rate can be performed. The fourth weight change rate can be obtained in the same way as the first weight change rate and the second weight change rate. The fourth weight change rate can be obtained after the precipitation sensor indicates that it is raining or snowing and then indicates that it is not raining or snowing. The fourth weight change rate can be obtained after a certain period of time has passed since it is indicated that it is not raining or snowing. That is, in order to obtain the fourth weight change rate, the server 110 may use at least some of the weight data obtained after a certain period of time has passed since it was indicated that it is not raining or snowing.

The server 110 may perform a step of acquiring the fifth weight change rate after a predetermined detection period of the fourth weight change rate. The fifth weight change rate can be obtained in the same way as the first weight change rate and the second weight change rate.

If the fifth weight change rate and the fourth weight change rate are negative numbers, and the fifth weight change rate is less than or equal to the fourth weight change rate, the server 110 may perform the step of generating a constant rate drying section alarm. The fact that the 5th weight change rate and the 4th weight change rate are negative may indicate that the weight of the waste is decreasing. Additionally, the fact that the fifth weight change rate is less than or equal to the fourth weight change rate may indicate that the degree of moisture reduction increases or remains constant over time. The constant rate drying section alarm indicates that the moisture drying amount per hour of the waste is constant. In other words, it can indicate that the weight of the waste is decreasing but is in a normal state.

The server 110 may generate an illegal disposal-related alarm when the value obtained by subtracting the fourth weight change rate from the fifth weight change rate is less than a predetermined threshold change rate. This is because there is a weight loss that exceeds the amount of water evaporation. Here, the critical rate of change can be a negative real number.

If the fifth weight change rate and the fourth weight change rate are 0 or the fifth weight change rate is greater than the fourth weight change rate, the server 110 may perform the step of generating a critical moisture content section alarm. The critical moisture content section may mean that the moisture in the waste is almost dry. Therefore, if the waste decreases rapidly in the future, the server 110 may generate an alarm related to illegal disposal.

In this way, the illegal dumping detection system 100 of the present disclosure can determine whether there is illegal dumping not only when it rains or snows, but also even after it rains or snows. Therefore, the illegal dumping detection system 100 of the present disclosure can effectively prevent illegal waste dumping.

For example, the map 1300 may display the first location 1310 where illegal disposal is suspected. Additionally, although not shown in FIG. 13, the current location of the vehicle may be displayed on the map 1300. In addition, when receiving an input (EX. touch, click) about the current location of the vehicle or a location where illegal disposal is suspected, the server 110 or the manager terminal 150 provides detailed information on the waste vehicle, such as contract information or driving information. Information can be displayed.

For example, a date when there was no illegal dumping can be displayed as “ZERO illegal dumping.” In addition, the vehicle's accumulated driving distance, number of illegal alarms, and actual number of illegal cases can be displayed. The illegal disposal-related alarm of this disclosure may be generated when illegal disposal is suspected. If an alarm related to illegal disposal is generated, the number of illegal alarms may increase. When an alarm related to illegal disposal is generated, the administrator can check directly to determine whether there has been illegal disposal. If there is illegal disposal, the manager can input that there is illegal disposal on the manager terminal 150 or server 110. . At this time, the actual number of illegal cases may increase.

In addition, referring to the table at the bottom of FIG. 14, the manager terminal 150 or the server 110 records the date and time when the illegal disposal-related alarm was generated, information on the vehicle related to the alarm, the location where the illegal disposal-related alarm was generated, and the vehicle. It can display at least one of the amount of waste loaded on the vehicle and the amount of change in the waste loaded on the vehicle. When receiving an input (EX. touch, click) for one row of the table at the bottom of FIG. 14, the manager terminal 150 or server 110 displays detailed information on the waste vehicle, such as contract information or driving information. can do.

Referring to Figure 15, the information in Figures 13 and 14 may be displayed on one screen.
