Description

[Technical Field]

[0001] The present invention relates to a detection processing system, a detection processing device, and a detection processing method for detecting smoke or fire in a garbage pit. [Background technology]

[0002] Conventionally, fire detection and extinguishing systems have been used to detect and extinguish fires in pits storing combustible materials, such as garbage pits. Patent Document 1 describes a fire detection and extinguishing system that can detect and extinguish fires in conjunction with an automatic garbage crane installed in a garbage pit. More specifically, Patent Document 1 discloses that a threshold value for determining whether or not a fire has occurred is set to an appropriate temperature (e.g., 50°C) that is lower than the temperature of the crane body, so that even if a temperature higher than the threshold value is measured at the location where the crane body is located, it is not determined that a fire has occurred.

[Brief explanation of the drawings]

[Figure 3] 1 is a flowchart of a detection processing method according to an embodiment of the present invention. [Figure 4] FIG. 1 is an image of the top surface of garbage stored in a garbage pit recognized by the detection and processing system. [Figure 5] 1 is an example image showing bounding boxes indicating smoke or fire detection. DETAILED DESCRIPTION OF THE INVENTION

[0022] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. A detection processing device according to an embodiment of the present invention is a device for detecting smoke or fire occurring in a garbage pit installed in a garbage disposal facility. Specifically, the detection processing device is a device that prevents erroneous detection by masking the detection results of a detection means that detects smoke or fire according to the status of equipment such as a garbage crane or a garbage input gate.

[0023] First, we will explain the garbage pit to which the detection and processing device is applied. As shown in Figure 1, the garbage pit 50 is a space for storing garbage (waste) transported by collection trucks, and has a substantially rectangular floor 50A. Burnable garbage, earth and sand, combustible residues separated from non-burnable garbage, etc. are thrown into the garbage pit 50.

[0024] A garbage crane 51 capable of transporting garbage W stored in the garbage pit 50 is installed on the ceiling of the garbage pit 50. The garbage crane 51 is a transport device that uses a bucket 52 to lift the garbage W and supply it to the incinerator. A monitoring room 53 that monitors the inside of the garbage pit 50 is installed in the garbage pit 50. Workers can operate the garbage crane 51 from the monitoring room 53. The garbage crane 51 may be controlled by automatic operation. The garbage pit 50 is provided with a plurality of garbage input gates 54 for inputting garbage transported by collection vehicles into the garbage pit 50. The plurality of garbage input gates 54 are provided in a direction perpendicular to the plane of the paper in FIG.

[0025] The garbage pit 50 is also provided with a water cannon 56 that sprays water in the event of a fire occurring in the stored garbage W. The water cannon 56 can spray water at a specific location on the garbage W in the garbage pit 50. The water cannon 56 may be a system that identifies the location of a fire using a sensor such as an infrared camera and automatically sprays water.

[0026] The detection processing device 100 includes a camera 57 that captures captured image data corresponding to a captured image whose subject is the garbage pit 50, and a notification unit 60 that notifies of the occurrence of smoke or fire in the garbage pit 50. An ITV camera, for example, can be used as the camera 57, which is capable of capturing image data that can be processed by a computer. The camera 57 can be placed in a position where it can capture an image of the entire top surface of the waste stored in the waste pit 50, for example, in the monitoring room 53.

[0027] The notification unit 60 includes a display unit 61 and an alarm unit 62. The display unit 61 is a device that displays characters, figures, images, videos, etc., such as a display. The alarm unit 62 is a traffic light that is more visible from a distance than the display unit 61, such as a PATLITE (registered trademark, patrol lamp), a rotating light, or a signal tower.

[0028] Next, the detection processing system 1 and the detection processing method will be described. As shown in Fig. 2, the detection processing system 1 includes an input means 2, a detection means 3, a calculation means 4, a determination means 5, and a notification control means 6. The detection processing system 1 includes a computer that has a processor such as a CPU (Central Processing Unit), a storage device, a communication device, an input / output means, etc., and executes various calculations according to a program, and the input means 2, the detection means 3, the calculation means 4, the determination means 5, the notification control means 6, etc. are implemented by the processor operating according to the program. The detection processing system 1 is also electrically connected to the bucket 52, the garbage disposal gate 54, and the water cannon 56 shown in Fig. 1, and can control these.

[0029] The detection processing system 1 also has a receiving means 8 that receives any instruction from an operator. The detection processing system 1 can process the instruction received via the receiving means 8. The reception via the receiving means 8 may be performed via a software button (icon) or a physical button.

[0030] As shown in Figure 3, the detection processing method using the detection processing system 1 includes a detection process P1 for detecting smoke or fire in the garbage pit 50 based on captured image data corresponding to an image whose subject is the garbage pit 50, a calculation process P2 for calculating the range of the top surface of the garbage W stored in the garbage pit 50 that includes external disturbances as a predetermined range, a determination process P3 for determining whether the position of the smoke or fire detected in the detection process P1 is included in the predetermined range calculated in the calculation process P2, and a notification control process P4 for causing the notification unit 60 to notify the occurrence of smoke or fire depending on the determination result of the determination process P3.

[0031] Fig. 4 is an image diagram of the top surface of the garbage in the garbage pit recognized by the detection processing system 1. As shown in Fig. 4, the top surface of the garbage in the garbage pit recognized by the detection processing system 1 is divided into a grid (a lattice). That is, the detection processing system 1 recognizes the position by dividing the top surface of the garbage in the rectangular garbage pit into multiple rectangles. In the following explanation, an example will be given in which the top surface of the garbage in the garbage pit is divided into a 10 x 6 grid. The detection processing system 1 does not need to recognize the top surface of the garbage in the garbage pit as being divided into a grid as shown in FIG. 4, and may recognize it at a higher resolution depending on the performance of the computer, etc.

[0032] The input means 2 receives, via the camera 57, captured image data corresponding to a captured image in which the subject is a garbage pit.

[0033] In the detection step P1, the detection means 3 detects smoke or fire and its position in the garbage pit 50 based on the captured image data input to the input means 2. The detection means 3 performs object recognition on the captured image data and detects the position of the smoke or fire contained in the captured image data. AI (artificial intelligence), machine learning, deep learning, etc. can be used for object recognition.

[0034] The detection processing system 1 further includes an acquisition means 9 that acquires reliability data (a score indicating the probability of smoke or fire being included) corresponding to the reliability (certainty) of the smoke or fire detected by the detection means 3.

[0035] FIG. 5 is an example of an image processed by the detection means 3, in which a bounding box B indicating that smoke has been detected is displayed. As shown in FIG. 5, the captured image data captures the entire top surface of the garbage W stored in the garbage pit 50. The detection means 3 detects smoke or fire along with reliability data R. For example, if the detection means 3 detects smoke and the reliability is 70%, it displays "SMOKE 70%". If the detection means 3 detects fire and the reliability is 30%, it displays "FIRE 30%".

[0036] The detection and treatment system 1 constantly acquires information (equipment information) about the bucket 52 that constitutes the garbage pit 50, the garbage input gate 54, the water cannon 56, the properties of the garbage input through the garbage input gate 54, and the like.

[0037] For the bucket 52 (garbage crane), operation information of the bucket 52, the position (horizontal position) of the bucket 52, height data corresponding to the height of the bucket 52 (height from the floor 50A), and orientation data corresponding to the direction of light hitting the bucket 52 are acquired. For the garbage input gate 54, information on whether the garbage input gate is open or closed is acquired. Regarding the water cannon 56, the direction of the water cannon 56 (the position of the garbage that is hit by the water sprayed from the water cannon 56) and operation information of the water cannon 56 are acquired. Property data corresponding to the properties of the waste put in through the waste input gate 54 can be obtained based on information that can be obtained from a collection vehicle, for example.

[0038] The detection processing system 1 further includes a discrimination means 10 that discriminates whether or not the bucket 52 has released the debris. Operation information of the bucket 52 is input to the discrimination means 10 at all times, and when the bucket 52 is in the open state, it determines that the bucket 52 has released the debris, and when the bucket 52 is in the closed state, it determines that the bucket 52 is holding the debris without releasing it, and outputs the discrimination result.

[0039] In the calculation step P2, the calculation means 4 calculates, based on the above-mentioned facility information, the range of the upper surface of the waste W stored in the waste pit 50 that includes disturbances as a predetermined range. A disturbance is an event that can be detected as smoke or fire by the detection means 3, in other words, an event that can cause the detection means to erroneously detect it as smoke or fire. The calculation means 4 calculates the following as the disturbance: (1) Shadow of garbage bucket 52 of garbage crane 51 (2) Soil and sand dumped into the garbage pit 50 from the garbage dump gate 54 (3) Garbage hit by water sprayed from water cannon 56 The processing of the calculation means 4 in response to the above three disturbances will be described below.

[0040] [1] Processing of garbage reflected by the garbage crane bucket as a disturbance First, a process will be described in which the waste W on which the shadow of the bucket 52 of the waste crane 51 is cast is treated as a disturbance. Garbage in which the shadow of the bucket 52 of the garbage crane 51 is cast may be detected as black smoke by the detection means 3, and may therefore be a disturbance to the detection means 3. The diagram shown in Figure 5 is an example in which garbage in which the shadow of the bucket 52 is cast is erroneously detected as smoke.

[0041] The calculation means 4 calculates the range of the top surface of the waste W stored in the waste pit 50 that includes disturbances (waste on which the shadow of the bucket 52 of the waste crane 51 is cast) as the predetermined range. Specifically, position information of the bucket 52 of the waste crane 51 is acquired, and the range within a predetermined distance from the position of the bucket 52 is calculated as the predetermined range. For example, if the position of the bucket 52 is the square at the "fifth row, fourth column" indicated by reference character C1 in FIG. 4, the predetermined range is calculated as "two squares" including the square C1, in other words, the squares adjacent in the row direction and the squares adjacent in the column direction with the square C1 at the center, and the range indicated by reference character D1 in FIG. 4 is calculated as the predetermined range.

[0042] The predetermined distance when the disturbance is garbage cast by the shadow of the bucket 52 of the garbage crane 51, the predetermined distance when the disturbance is earth and sand dumped into the garbage pit 50 from the garbage dump gate 54, and the predetermined distance when the disturbance is the portion of the garbage that is hit by water sprayed from the water cannon 56 may be the same. A memory control means (not shown) stores distance data corresponding to the predetermined distances in a memory device.

[0043] The calculation means 4 can also calculate the predetermined range based on height data corresponding to the height information of the bucket 52. Since the position of the shadow of the bucket 52 changes depending on the height of the bucket 52, the calculation means 4 calculates the specified range based on the height data as well, making it possible to more reliably calculate the range that includes the garbage that is reflected by the changing shadow.

[0044] The calculation means 4 can also calculate the predetermined range based on direction data corresponding to the direction of light hitting the bucket 52. Since the position of the shadow of the bucket 52 changes depending on the direction of the light that hits the bucket 52, the calculation means 4 calculates the specified range based on the direction data corresponding to the direction of the light, thereby making it possible to more reliably calculate the range that includes the garbage that is reflected by the changing shadow.

[0045] In the judgment step P3, the judgment means 5 determines the position of the smoke or fire based on the captured image data processed by the detection means 3 as shown in Figure 5, and judges whether the position of the smoke or fire is included in a predetermined range calculated by the calculation means 4. For example, if the position indicated by S1 in Figure 4 is detected as the position of smoke or fire based on the captured image data processed by the detection means 3, and the calculation means 4 calculates the range of D1 in Figure 4 as the predetermined range, it is determined that the position of smoke or fire is not included in the predetermined range. On the other hand, if the detection means detects the position indicated by S2 in Fig. 4 as the position of smoke or fire, and the calculation means 4 calculates the range D1 in Fig. 4 as the predetermined range, it is determined that the position of smoke or fire is included in the predetermined range. In other words, if any of the multiple squares that make up the predetermined range matches the square that is determined to be the position of smoke or fire, it is determined that the position of smoke or fire is included in the predetermined range.

[0046] In a notification control step P4, the notification control means 6 notifies the notification unit 60 of the occurrence of smoke or fire according to the determination result of the determination means 5. Specifically, when it is determined that the location of the smoke or fire is not within a predetermined range (the detection result of the detection means 3 is correct), it activates the alarm unit 62 (such as a patrol lamp) constituting the notification unit 60 and causes the display unit 61 (such as a display) to display that smoke or fire has occurred.

[0047] On the other hand, if it is determined that the position of the smoke or fire is within a predetermined range (the detection result of the detection means 3 is a false detection), the alarm unit 62 constituting the notification unit 60 is not activated, and a message is displayed on the display unit 61 indicating that notification by the notification unit 60 is being suppressed (that smoke or fire has been detected by the detection means 3, but notification by the determination means 5 is being suppressed). In other words, if smoke or fire is detected near the disturbance, the output of the alarm unit 62, which has better visibility from a distance than the display unit 61, is masked to prevent false alarms.

[0048] Here, when the receiving means 8 receives any instruction from the worker, the notification control means 6 causes the alarm unit 62 to issue an alert. In other words, when the worker can visually recognize a fire but the alarm unit 62 does not operate and an image indicating that notification of the occurrence of smoke or fire is being suppressed is displayed on the display unit 61, the notification control means 6 can instruct the receiving means 8 to cause the alarm unit 62 to issue an alert.

[0049] The notification control means 6 can also cause the notification unit 60 to notify the occurrence of smoke or fire in accordance with the determination result of the determination means 10 that determines whether the bucket 52 has released the garbage. When the bucket 52 is in the open state and releases the garbage, smoke is generated by the falling garbage, and this smoke may be erroneously detected by the detection means 3. In response to this, by referring to the determination result of the discrimination means 10, for example, by lowering the reliability of the smoke detected by the detection means 3 when the bucket 52 releases the garbage, it is possible to reduce the impact of erroneously detecting smoke or fire.

[0050] Furthermore, the notification control means 6 has a function of notifying the notification unit 60 of the occurrence of smoke or fire based on the determination result of the determination means 5 and the reliability data obtained by the acquisition means 9. If the reliability is equal to or greater than a predetermined threshold (e.g., 90%), the notification control means 6 causes the notification unit 60 to notify the occurrence of smoke or fire even if the determination means 5 determines that the location of the smoke or fire is within a predetermined range. The above-mentioned predetermined reliability threshold can be set as appropriate. This makes it possible to prioritize the reliability data from the acquisition means 9 over the judgment results from the judgment means 5, thereby preventing the occurrence of smoke or fire from being overlooked due to an incorrect judgment result from the judgment means 5.

[0051] In addition, the notification control means 6 also has the function of notifying the notification unit 60 of the occurrence of smoke or fire when the location of smoke or fire detected by the detection means 3 is determined to be within a predetermined range and the garbage crane 51 remains stopped for a predetermined period of time (e.g., 10 minutes). If the location of detected smoke or fire is within a specified range and the garbage crane 51 continues to stop, there is a risk that when smoke or fire actually occurs, it will be late in noticing the occurrence of smoke or fire, which could lead to the smoke or fire spreading. This function reduces the delay in noticing the occurrence of smoke or fire caused by the garbage crane 51 continuing to stop and concealing the smoke or fire.

[0052] In addition, the notification control means 6 also has the function of causing the notification unit 60 to notify the occurrence of smoke or fire when the detection means 3 determines that the location of the smoke or fire detected is not within a predetermined range, and then the determination means 5 determines that the smoke or fire is within a predetermined range. For example, if the garbage crane 51 moves close to a location where smoke or a fire has already occurred, the determination means 5 may determine that the location of the smoke or fire is within a predetermined range, which may result in the occurrence of smoke or a fire not being notified. This function can prevent the occurrence of smoke or a fire from being notified.

[0053] As described above, according to the above process, it is possible to have the notification unit 60 notify the occurrence of smoke or fire depending on whether the location of the detected smoke or fire is within a predetermined range that includes external disturbances, thereby reducing the impact of such erroneous detection. In addition, by treating the garbage in which the shadow of the bucket 52 of the garbage crane 51 is cast as a disturbance, the effects of false detection of smoke or fire can be more reliably reduced.

[0054] [2] Processing of soil and sand dumped into the garbage pit from the garbage dump gate as a disturbance Next, a process will be described in which the soil and sand dumped into the garbage pit 50 from the garbage dump gate 54 is treated as a disturbance. The black soil and sand dumped into the garbage pit 50 from the garbage dump gate 54 may be detected as black smoke by the detection means 3, and may therefore become a disturbance to the detection means 3. The calculation means 4 calculates the range of the upper surface of the waste W stored in the waste pit 50 that includes disturbances (black soil and sand dumped into the waste pit 50) as the predetermined range. Specifically, information on the opening and closing of the waste input gate 54 is acquired, and the calculation means 4 calculates the range that includes the soil and sand dumped into the waste pit 50 from the waste input gate 54 as the predetermined range. For example, if the position of the waste input gate 54 is the square at "row 8, column 1" indicated by reference character C2 in FIG. 4, the calculation means 4 calculates the predetermined distance as "two squares" including the square C2, in other words, the range indicated by reference character D2 is calculated as the predetermined range, with the square C2 at the center, including the squares adjacent in the row direction and the squares adjacent in the column direction.

[0055] The determination method by the determination means 5 and the notification method by the notification control means 6 are the same as the process of [1] treating garbage that casts a shadow of the garbage crane bucket as a disturbance.

[0056] The notification control means 6 has the function of causing the notification unit 60 to notify the occurrence of smoke or fire when the determination means 5 determines that the location of smoke or fire is within a predetermined range and the garbage disposal gate 54 closes. If the garbage input gate 54 is not open, garbage will not be input from the garbage input gate 54 into the garbage pit 50. This function can cause the notification unit 62 to issue a notification by canceling the predetermined range calculated by the calculation means 4, for example.

[0057] In addition, the notification control means 6 has the function of notifying the notification unit 60 of the occurrence when the garbage input gate 54 is opened after the garbage input gate 54 is closed and the location of smoke or fire is determined to be within a predetermined range.

[0058] For example, if the garbage input gate 54 near a location where smoke or a fire has already occurred opens, the determination means 5 may determine that the location of the smoke or fire is within a predetermined range, which may result in the occurrence of smoke or a fire not being notified. This function can prevent the occurrence of smoke or a fire from being notified.

[0059] Furthermore, the notification control means 6 has a function of causing the notification unit 60 to notify the occurrence based on property data corresponding to the properties of the waste thrown in through the waste throw-in gate 54. Depending on the nature of the waste, false detection of smoke or fire may be unlikely even when the waste is dumped through the waste dump gate. For example, if pruning branches, wood, etc. are dumped into the waste pit 50, false detection of smoke or fire is unlikely. This function allows for more reliable notification of the occurrence of smoke or fire.

[0060] As described above, according to the above processing, by treating the soil and sand dumped into the garbage pit 50 from the garbage dump gate 54 as a disturbance, the effects of false detection of smoke or fire can be more reliably reduced.

[0061] [3] Processing of debris hit by water sprayed from a water cannon as a disturbance Next, a process will be described in which dust hit by water sprayed from the water gun 56 is treated as a disturbance. The dust that is hit by the water sprayed from the water cannon 56 may cause droplets to be detected as white smoke by the detection means, and may therefore become a disturbance to the detection means 3.

[0062] The calculation means 4 calculates the range of the upper surface of the waste W stored in the waste pit 50 that includes disturbances (waste that will be hit by water sprayed from the water cannon 56) as the predetermined range. Specifically, it acquires positional information of the waste that will be hit by water sprayed from the water cannon 56, and calculates the range within a predetermined distance from the position of the waste that will be hit by water sprayed from the water cannon 56 as the predetermined range. The method of calculating the predetermined range is the same as the process in [1] where waste that reflects the shadow of the bucket of the waste crane is treated as a disturbance.

[0063] The calculation means 4 can also calculate the predetermined range based on the direction information of the water cannon 56. This makes it possible to more reliably include trash that is hit by water sprayed from the water cannon 56 within the predetermined range.

[0064] The determination method by the determination means 5 and the notification method by the notification control means 6 are the same as the process of [1] treating garbage that casts the shadow of the garbage crane bucket as a disturbance.

[0065] The notification control means 6 has a function of notifying the notification unit of the occurrence of smoke or fire when the determination means 5 determines that the position of smoke or fire detected by the detection means 3 is within a predetermined range and, by referring to the operation information of the water cannon 56, recognizes that the water cannon 56 will stop spraying water. When the water discharge from the water cannon 56 is stopped, the water discharged from the water cannon 56 does not hit the garbage. Therefore, the influence of erroneous detection of smoke or fire can be more reliably reduced.

[0066] In addition, the notification control means 6 has a function of notifying the notification unit of the occurrence when water discharge from the water cannon 56 is stopped and water discharge from the water cannon 56 is started after the determination means determines that it is within the predetermined range. This function can prevent the occurrence of smoke or a fire from going unnoticed, for example, when the water cannon 56 starts spraying water when the smoke or fire has already occurred.

[0067] As described above, according to the above process, the influence of erroneous detection of smoke or fire can be more reliably reduced by treating the debris that hits the water sprayed from the water cannon 56 as a disturbance. In addition to the above-described processing, even if the water cannon 56 is activated in response to a fire that has occurred and the notification unit 60 notifies the fire department, the alarm unit 62 can be prevented from activating again due to a false detection after the fire has been extinguished.
