Description

Technical Field

[0001] This invention relates to a control system for preventing fires. Background Technology

[0002] In recent years, various battery-powered devices, such as smartphones, laptops (Personal Computers), drones, motorcycles, household batteries, and motor vehicles, have become increasingly common. With this proliferation, the risk of fires caused by batteries has become more apparent. In the event of a battery fire, the battery will initially generate continuous heat. When the battery temperature reaches a predetermined level, thermal runaway occurs, leading to a fire. A battery that has caught fire due to thermal runaway becomes difficult to extinguish.

[0003] As described above, in the cargo hold of a motor vehicle transport vessel, thousands of vehicles carrying potentially flammable, high-capacity batteries are positioned at intervals of several tens of centimeters in all directions. Therefore, if a fire breaks out in any one vehicle due to a battery fire, it is extremely difficult to extinguish. Consequently, when a fire starts in one vehicle, it can quickly spread to surrounding vehicles. Thus, if a fire originates in a vehicle within the cargo hold, extinguishing it becomes exceptionally difficult.

[0004] Therefore, in the past, automatic fire reporting equipment for detecting fires has been installed in motor vehicle transport vessels. This automatic fire reporting equipment mainly consists of a sensor that activates by detecting smoke, fire, heat, etc., generated by a fire, and a receiver that reports the fire to the crew based on the activation of the sensor.

[0005] However, automatic fire reporting devices constructed in this way report fires only after they have occurred. Therefore, even if they detect a fire after the smoke, flames, or heat have become apparent, they are sometimes unable to cope with fires that spread rapidly as described above.

[0006] To address this problem, for example, Japanese Patent Application Publication No. 2005-312642 (Patent Document 1) discloses a fire detection and notification system for a motor vehicle transport vessel. This system includes: multiple sensor units, mainly including fire detection temperature sensors that detect the presence of a fire based on information such as the surface temperature of the motor vehicle, distributed in the ceiling of the cargo hold; multiple control units that receive detection signals from the fire detection temperature sensors and the position information of the sensor units; and a central monitoring device connected to these multiple control units via a communication bus.

[0007] According to such a fire detection and notification system for a motor vehicle transport vessel, a temperature sensor for fire detection can quickly detect signs of fire before it ignites, and the control unit transmits the detection signal to a central monitoring device. Therefore, according to the fire detection and notification system disclosed in Patent Document 1, it is expected that fires can be prevented from occurring in the first place.

[0008] Existing technical documents Patent documents Patent document 1: Japanese Patent Application Publication No. 2005-312642. Summary of the Invention

[0009] The problem that the invention aims to solve To implement the fire detection and notification system for a motor vehicle transport vessel disclosed in Patent Document 1, a control unit that receives detection signals generated by sensor units needs to be connected via a communication unit to a central monitoring device located in the steering room or similar space. Furthermore, the central monitoring device needs to be optimized to accommodate this fire detection information system. Therefore, implementing this fire detection and notification system requires considerable effort and cost.

[0010] The present invention has been made in view of the above aspects, and its object is to provide a control system that can reduce the risk of fire occurrence by using existing automatic fire reporting equipment.

[0011] Solution for solving the problem The control system according to the present invention comprises: a sensor separately disposed from a sensor in a space where an automatic fire reporting device is provided, and detecting the state of an item that may be on fire; an actuating device that performs processing to actuate the sensor; and a control device that causes the actuating device to perform the processing when the state of the item detected by the sensor meets predetermined conditions. The state of the item is at least one of the following: the temperature of the item, a pressure change in the internal pressure of the item, an intensity change in infrared radiation emitted by the item, an intensity change in ultraviolet radiation emitted by the item, and deformation of the item.

[0012] Invention Effects According to the present invention, a control system is provided that can reduce the risk of fire by using existing automatic fire reporting equipment. Attached Figure Description

[0014] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments shown below illustrate a control system used in a motor vehicle transport vessel, where a motor vehicle, as an example of an article, is loaded in a cargo hold, as an example of a space. Furthermore, in the embodiments shown below, the same or common parts are labeled with the same symbols in the drawings, and their descriptions are not repeated.

[0015] [Implementation Method 1] Figure 1 This diagram illustrates the internal equipment configuration of a motor vehicle transport vessel employing the control system and fire hazard reporting system of this embodiment. Figure 2 This is a schematic diagram of a motor vehicle equipped with the control system of this embodiment, viewed from the front side. Figure 3 This is a schematic diagram of a motor vehicle equipped with the control system of this embodiment, viewed from the side. First, before describing the control system 101 and the fire hazard reporting system of this embodiment, refer to... Figures 1 to 3 The structure of the motor vehicle handling vessel 900, which employs the control system 101, is described in general.

[0016] like Figures 1 to 3 As shown, the motor vehicle handling vessel 900 mainly comprises a steering room 901 and a cargo hold 902. Multiple crew members CR1 are stationed in the steering room 901, who are responsible for steering the vessel and monitoring the interior of the ship. Additionally, in... Figure 1 The image shows one of the multiple flight attendants, CR1 (described later). Figure 4 and Figure 19 The same applies to Naka.

[0017] Cargo holds 902 are located on multiple floors within the motor vehicle handling vessel 900. In each cargo hold 902, multiple motor vehicles 200 are closely arranged in a manner that positions them relative to each other at approximately 20cm intervals in all four directions. Furthermore, the ceiling 902a of the cargo hold 902 is configured to be raised and lowered according to the height of the motor vehicles 200. As an example, the distance between the floor 902b and the ceiling 902a of the cargo hold 902 (i.e., the ceiling height) is approximately 2m.

[0018] Additionally, in cargo hold 902, crew member CR2 conducts patrols and monitoring of cargo hold 902. Figure 1 The image shows one of the multiple flight attendants, CR2 (described later). Figure 4 , Figures 6 to 8 , Figure 11 , Figures 18 to 20 The same applies to Naka.

[0019] On the motor vehicle handling vessel 900, an automatic fire reporting device 300 is installed to enable rapid firefighting operations in the event of a fire on the motor vehicle handling vessel 900. The automatic fire reporting device 300 includes multiple sensors 301 and a receiver 302.

[0020] Multiple sensors 301 are positioned relative to each other at predetermined intervals on the ceiling 902a of the cargo compartment 902. Thus, the crew member CR1 can receive a predetermined signal P (refer to...) from the activated sensor 301 and transmit it to the receiver 302. Figure 4 This can be used to identify the approximate location of a fire.

[0021] In this example, each sensor 301 is a so-called photoelectric point sensor for sensing smoke. The photoelectric point sensor has a light-emitting part and a light-receiving part inside. Light emitted from the light-emitting part collides with smoke particles entering the sensor and is diffusely reflected. The diffusely reflected light is then sensed by the light-receiving part. By sensing the light through the light-receiving part, the sensor activates.

[0022] Furthermore, smoke-sensing sensors are not limited to photoelectric point sensors. Smoke-sensing sensors can also be photoelectric discrete sensors, etc.

[0023] When sensor 301 is activated, receiver 302 reports a fire to crew members CR1, etc., by receiving signal P transmitted from sensor 301. Receiver 302 is typically located in the control room 901. Receiver 302 mainly includes a monitor 302a, a speaker 302b, and an operating unit 302c. The monitor 302a displays the alarm and the location of the activated sensor 301, and the speaker 302b reports the alarm at least audibly (see below). Figure 4 ).

[0024] Sensor 301 and receiver 302 are connected by wiring (see reference). Figure 1 (The dotted line in the diagram). The signal P emitted by the sensor 301 in detecting smoke and taking action is transmitted to the receiver 302 via this wiring. The receiver 302 receives the signal P emitted by the sensor 301 and reports the fire to the crew member CR1 in the control room 901.

[0025] like Figure 2 and Figure 3 As shown, each motor vehicle 200 disposed in the cargo compartment 902 has a built-in battery 201 for supplying power to the electric motor that serves as the drive source. Lithium-ion batteries are preferably used as the battery 201, for example. Furthermore, in Figures 1 to 3In the example of "motor vehicle 200", a private car is shown, but it is not limited to this. Motor vehicle 200 only needs to have an internal combustion engine as a drive source, an electric motor as a drive source, or a combination of an internal combustion engine and an electric motor as a drive source, and it needs to have wheels. For example, motor vehicle 200 can be a motorcycle, bus, truck, etc.

[0026] Battery 201 is a potentially flammable item. Specifically, when battery 201 deteriorates, flammable gases may be produced due to the oxidation of the internal electrolyte. When battery 201 is subjected to an impact while flammable gases are present, it may sometimes ignite. Sometimes, problems during the manufacturing process of battery 201 can cause it to catch fire. Sometimes, battery 201 may catch fire due to overcharging.

[0027] As known as the "tracking phenomenon," battery-powered vehicles can sometimes catch fire even when the power is off. Specifically, even when the power is off, leakage can occur when moisture and foreign objects such as dust are present in the wiring connected to the battery. As a result, the battery can sometimes catch fire.

[0028] Figure 4 It is used to explain the composition Figure 1 The diagram shows the hardware structure of each device in the control system. (Refer to...) Figures 2 to 4 The structure of the control system 101 will be described.

[0029] like Figures 2 to 4 As shown, the control system 101 includes a sensor 10, an actuation device 20, a control device 30, an alarm device 40, and a power supply 50. In the control system 101, the sensor 10, actuation device 20, control device 30, alarm device 40, and power supply 50 are built into a housing 70. That is, in this embodiment, the control system 101 is configured as a single unit.

[0030] Sensor 10 and sensor 301 of automatic fire reporting device 300 are separately provided. In this embodiment, sensor 10 detects the temperature of vehicle 200 as the state of vehicle 200. Specifically, sensor 10 detects the surface temperature of bottom surface 200a of vehicle 200. More specifically, sensor 10 detects the surface temperature of the portion of bottom surface 200a located near (more specifically, directly below) battery 201.

[0031] As sensor 10, a temperature sensor is used. Temperature sensors can be of two types: contact and non-contact. Examples of contact temperature sensors include thermocouples, platinum resistance thermometers, thermistors, bimetallic thermometers, liquid-filled thermometers, and mercury thermometers. Non-contact temperature sensors determine temperature by measuring infrared radiation emitted from an object. Non-contact temperature sensors may be thermal (uncooled) or quantum (cooled) types.

[0032] In this embodiment, a non-contact temperature sensor is used as sensor 10. Since it is a non-contact temperature sensor, the surface temperature of the bottom surface 200a can be detected regardless of its shape.

[0033] From the viewpoint of partial or overall redundancy, it is preferable to provide multiple sensors 10. Thus, even if one sensor 10 fails, the other sensors 10 can take over the function.

[0034] When the battery 201 heats up, heat is transferred from the battery 201 to the bottom surface 200a. Therefore, by detecting the surface temperature of the bottom surface 200a by the sensor 10, abnormal heating of the battery 201 can be detected.

[0035] The actuation device 20 performs a process to activate the sensor 301. The content of this process varies depending on the type of sensor 301 installed in the cargo hold 902; in this embodiment, the actuation device 20 only needs to emit either smoke or heat. In this example, since the sensor 301 detects smoke, the actuation device 20 emits smoke as described above. Therefore, in this embodiment, the actuation device 20 includes a smoke generator. The smoke generator can use a smoke-generating agent composed of gunpowder or the like, or it can use compressed gas composed of powdered extinguishing agents or nano-zeolites.

[0036] The control device 30 acquires temperature information from the sensor 10, indicating the temperature detected by the sensor 10, according to a predetermined control cycle T (e.g., every 1 second). When the temperature of the vehicle 200 detected by the sensor 10 meets a predetermined condition, the control device 30 causes the actuation device 20 to perform a warning process. Specifically, when the surface temperature of the bottom surface 200a of the vehicle 200 detected by the sensor 10 is above a set temperature V1, the control device 30 generates smoke from the actuation device 20.

[0037] In the event of abnormal heating within the battery 201, the temperature of the battery 201 gradually rises from its normal state, eventually reaching a predetermined temperature where thermal runaway occurs and the battery ignites. Therefore, the surface temperature of the bottom surface 200a of the battery 201 when it reaches a predetermined temperature lower than the ignition temperature is preset as a set temperature V1. Thus, the control device 30 can generate smoke from the actuation device 20 in the stage before the battery 201 ignites. In this example, the set temperature V1 is 80°C. However, the set temperature V1 is not limited to 80°C and can be set appropriately.

[0038] As key components, the control device 30 includes a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), and flash memory for executing programs. The CPU executes programs to perform various processes as described in this embodiment.

[0039] Specifically, the CPU (Arithmetic Unit) performs prescribed calculations based on the temperature information obtained from the sensor 10. ROM and flash memory store data non-volatilely. Flash memory stores the aforementioned program. RAM volatilely stores data generated by the CPU executing the program. The various components of the control device 30 are interconnected via a data bus.

[0040] The alarm device 40 provides an alarm to the area around the frame 70 via sound and / or light. In this embodiment, the alarm device 40 uses a buzzer that continuously emits sound and light (typically a flash). However, the alarm device 40 is not limited to this; it can be any structure that provides an alarm to the area around the frame 70 via at least one of sound and light.

[0041] Power is supplied to the actuation device 20, control device 30, and alarm device 40 via a power supply 50 built into the housing 70. In this example, the power supply 50 is a primary battery. Primary batteries are inexpensive and readily available worldwide. Alternatively, the power supply 50 can be a primary battery, a secondary battery, or any power source supplied from the ship's power supply via an AC / DC (Alternating Current / Direct Current) converter that converts AC voltage to DC voltage, or a USB (Universal Serial Bus) cable.

[0042] The frame 70 has a generally cuboid shape. The frame 70 is configured to abut against a portion of the bottom surface 200a of the vehicle 200 near the battery 201. Specifically, a magnet (not shown) is provided on the portion of the outer surface of the frame 70 opposite to the bottom surface 200a. The frame 70 is mounted on the bottom surface 200a by the magnetic force of the magnet.

[0043] Furthermore, the frame 70 is not limited to a roughly rectangular shape and can be modified appropriately. Regarding the mounting method of the frame 70 to the bottom surface 200a, it is not limited to the magnetic force of a magnet. For example, the frame 70 can also be mounted to the bottom surface 200a by the adhesive force of an adhesive applied to the portion of the outer surface of the frame 70 opposite to the bottom surface 200a.

[0044] After the vehicle 200 is loaded onto the vehicle transport vessel 900, the vehicle 200 is secured in position using lashing straps to prevent movement during navigation. The installation of the frame 70 onto the bottom surface 200a is typically performed simultaneously with the installation of the lashing straps onto the vehicle 200. The removal of the frame 70 from the bottom surface 200a occurs before the vehicle 200 is unloaded from the vehicle transport vessel 900. The removal of the frame 70 from the bottom surface 200a is performed simultaneously with the release of the vehicle 200 from its position secured using the lashing straps.

[0045] A fire hazard reporting system, comprising a control system 101 configured as described above and an automatic fire reporting device 300 having a sensor 301 and a receiver 302, is capable of reporting fire hazards caused by a motor vehicle 200 located in a cargo compartment 902 equipped with a sensor 301. This will be discussed in detail later.

[0046] Figure 5 It is used to explain in Figure 4 A flowchart illustrating the processing flow performed in the control system shown. (Refer to...) Figure 5 This will explain the processing performed in the control system 101.

[0047] In this example, the following processes performed by the control system 101 begin after a predetermined time (e.g., 30 minutes) has elapsed since the loading of the vehicle 200 onto the vehicle transport vessel 900 has been completed. Specifically, the following processes are performed after a predetermined time has elapsed since the housing 70 has been installed onto the bottom surface 200a of the vehicle 200. More specifically, the following processes are performed after a predetermined time has elapsed since a switch (e.g., a power switch or a switch that initiates operation) located on the housing 70 has been turned on by the user.

[0048] The reason for delaying the processing time is as follows. After the vehicle 200 is loaded onto the vehicle transport vessel 900, the battery 201 becomes considerably hot due to the operation performed for loading. It is necessary to prevent the control system 101 from performing the following processing based on the increased surface temperature of the bottom surface 200a caused by this heat. Therefore, the processing is delayed for the specified time as described above. Furthermore, from the viewpoint of preventing misoperation, the switch is preferably configured not to protrude from the outer surface of the housing 70.

[0049] like Figure 5 As shown, in step S1, the control device 30 determines whether the predetermined control period T has arrived. If it is determined that the control period T has arrived (the case is "yes" in step S1), the control device 30 causes the process to proceed to step S2. If it is determined that the control period T has not arrived (the case is "no" in step S1), the control device 30 causes the process to proceed to step S1.

[0050] In step S2, the control device 30 obtains temperature information from the sensor 10, showing the surface temperature of the bottom surface 200a of the vehicle 200 detected by the sensor 10. After step S2, in step S3, the control device 30 determines whether the surface temperature of the bottom surface 200a of the vehicle 200 is above a set temperature V1, which is a first temperature.

[0051] If the surface temperature of the bottom surface 200a is determined to be above the set temperature V1 (if "Yes" is selected in step S3), the control device 30 activates the alarm device 40 in step S4, continuously generating sound and light (typically flashing). This reports the occurrence of an anomaly to the surrounding area. After a certain period of time following the activation of the alarm device 40, the actuation device 20 is activated in step S5 to emit smoke.

[0052] If the surface temperature of the bottom surface 200a is determined to be lower than the set temperature V1 (the case where "No" is indicated in step S3), the control device 30 causes the process to proceed to step S1. Alternatively, the control device 30 may execute the process of step S5 before the process of step S4. Or, the control device 30 may execute the processes of step S4 and step S5 simultaneously.

[0053] Figure 6 It is used for explanation Figure 4 A schematic diagram of the cargo hold showing the operational state of the actuators. (Refer to...) Figure 4 and Figure 6 This will explain the processing performed by the control system 101 and the processing performed by the fire symptom reporting system equipped with the control system 101.

[0054] As described above, the control device 30 causes the actuation device 20 to operate, thereby, as Figure 4 and Figure 6 As shown, smoke 800 is emitted from a smoke generator included in the actuation device 20. The smoke 800 diffuses around the frame 70. The diffused smoke 800 is detected by a sensor 301 installed on the ceiling 902a. The diffused smoke 800 is typically detected by the sensor 301 installed on the ceiling 902a near the vehicle 200, which is equipped with a control system 101 that has the actuation device 20 actuated.

[0055] Smoke 800 is detected by sensor 301, causing sensor 301 to activate. When sensor 301 activates, it sends a signal P to receiver 302. Upon receiving signal P, receiver 302 displays an alarm on monitor 302a or generates an alarm on speaker 302b. Thus, the crew member CR1, located in the control room 901, can be aware that battery 201 is in an abnormal temperature state. That is, the crew member CR1 can be aware of signs of a fire caused by battery 201.

[0056] Thus, according to the control system 101, the automatic fire reporting device 300 can be activated before the battery 201 catches fire. Therefore, crew members CR1, CR2, etc., can quickly take appropriate pre-planned actions before the battery 201 catches fire. As a result, according to the control system 101, the risk of a fire caused by the motor vehicle 200 in the cargo compartment 902 can be reduced.

[0057] The control system 101 uses the automatic fire reporting device 300, which is an existing device of the motor vehicle transport vessel 900, to report signs of a fire caused by the motor vehicle 200. Therefore, the work required to implement the control system 101 is essentially just to install the control system 101 on the motor vehicle 200.

[0058] As described above, the control system 101 allows for the use of existing automatic fire reporting equipment to reduce the risk of fire. Furthermore, the control system 101 can be easily integrated into the motor vehicle transport vessel 900.

[0059] When the control system 101 is used, smoke 800 generated by the actuation device 20 is emitted from below the vehicle 200, which carries a battery 201 at an abnormal temperature. As a result, the crew member CR2, located in the cargo hold 902, can instantly determine the position of the vehicle 200 equipped with the smoke-emitting control system 101 by visually observing the emitted smoke. Therefore, the crew member CR2 and others can quickly take appropriate action before the battery 201 catches fire. Thus, the risk of a fire caused by the vehicle 200 in the cargo hold 902 can be further reduced.

[0060] Furthermore, in the control system 101, while the actuating device 20 emits smoke 800, the alarm device 40 continuously emits sound and light below the vehicle 200. Therefore, the crew member CR2 can also instantly determine the location of the vehicle 200 through the sound and light emitted by the alarm device 40. Thus, the risk of a fire caused by the vehicle 200 in the cargo hold 902 can be further reduced.

[0061] Furthermore, in this embodiment, the configuration of the housing 70 can be appropriately modified within the range where the sensor 10 can detect the occurrence of anomalies in the vehicle 200. For example, as described above, the housing 70 can be configured to abut against the bottom surface 200a of the vehicle 200. Thus, according to this example, the sensor 10 can be installed at a location where anomalies in the vehicle 200 can be reliably detected. That is, according to this example, the position of the sensor 10 can be appropriately modified so that the object to be detected (a potentially flammable item) is not located in the blind spot of the sensor 10. Therefore, according to this example, it is possible to prevent the sensor 10 from missing the occurrence (manifestation) of anomalies and the delay in the discovery of anomalies caused by such missed detections. According to this example, initial actions against anomalies in the vehicle 200 can be performed quickly.

[0062] Furthermore, in this embodiment, the following example is used: when the surface temperature of the bottom surface 200a of the vehicle 200 detected by the sensor 10 becomes a set temperature V1 (80°C in this example) or higher, the control device 30 causes the actuation device 20 to perform processing. However, the condition that the surface temperature should meet for the control device 30 to cause the actuation device 20 to perform processing is not limited to this. For example, the condition could also be that the change in surface temperature per unit time becomes a predetermined threshold or higher.

[0063] Furthermore, in this embodiment, the following example is provided: the control system 101 is configured to generate smoke from the actuating device 20 before the battery 201 located inside the vehicle 200 catches fire. However, the control system 101 may also be configured to generate smoke from the actuating device 20 after the battery 201 has caught fire. That is, the control system 101 may also be configured to generate smoke from the actuating device 20 before the outer surface of a potentially flammable item ignites due to the fire, in the event of a fire inside the item. In this case, by employing the control system 101, the risk of fire can also be reduced by using existing automatic fire reporting equipment.

[0064] In this embodiment, the following example is used: a motor vehicle transport vessel 900 in which a motor vehicle 200, including a battery 201, is disposed in a cargo hold 902 equipped with a sensor 301 and an automatic fire reporting device 300. However, the control system 101 is not limited to this; it can also be used in motor vehicle transport vessels other than those where a motor vehicle is disposed in a cargo hold.

[0065] As an example, the control system 101 can also be used in a cargo warehouse equipped with sensors for automatic fire reporting devices and a cargo hold (space) containing a large-capacity battery system (item) such as a household storage battery.

[0066] As another example, the control system 101 can also be used in aircraft equipped with sensors for automatic fire reporting devices and a cargo hold (space) containing containers (items) such as spray cans.

[0067] As yet another example, the control system 101 can also be used for freight trains equipped with sensors for automatic fire reporting devices and containers (spaces) containing smartphones (items) with batteries inside.

[0068] As yet another example, the control system 101 can also be used in ships equipped with sensors that have automatic fire reporting devices and cargo holds (spaces) configured with battery-powered unmanned or manned drones (items).

[0069] Thus, items that could potentially catch fire could be various goods transported by ships, airplanes, or freight trains, or various goods stored in warehouses.

[0070] Furthermore, items that may catch fire are not limited to cargo; they can also include equipment (machinery) located in spaces equipped with sensors for automatic fire reporting. For example, items that may catch fire could be engines, generators, or purifiers located in the engine room of a ship.

[0071] <Variation Example> (First variation) Figure 7 This is a schematic diagram of the cargo hold used to illustrate the operational state of the actuating device in the first modified example. Referring below... Figure 7 The control system 101A of the first modified embodiment 1 will be described.

[0072] like Figure 7 As shown, in this modified example, the control system 101A has a housing 70A instead of a housing 70. The configuration of the housing 70A is different between the control system 101A and the control system 101.

[0073] Specifically, in the control system 101, the frame 70 and the portion of the bottom surface 200a of the vehicle 200 located near (more specifically, directly below) the battery 201 are configured to abut (see reference). Figure 2 On the other hand, in the control system 101A, the frame 70A is disposed near the vehicle 200 without contacting it. More specifically, in the control system 101A, the frame 70A is mounted on a portion of the floor 902b of the cargo compartment 902, which is located directly below the battery 201 in the bottom surface 200a of the vehicle 200.

[0074] With the control system 101A configured in this way, the effects corresponding to those described in the above embodiments can be obtained. Therefore, according to the control system 101A, the risk of fire can be reduced by using existing automatic fire reporting equipment.

[0075] (Second variation) In this modified example, it is described that the automatic fire reporting device has a structure in which a sensor that at least senses ultraviolet light is used instead of a sensor 301 that senses smoke. Figure 8 This is a schematic diagram of the cargo hold used to illustrate the operational state of the actuating device in the second modification example. The following refers to... Figure 8 The control system 101B of the second variation of Embodiment 1 will be described.

[0076] like Figure 8 As shown, in this modified example, the automatic fire reporting device 300 has multiple sensors 301A and a receiver 302. Specifically, sensors 301A are provided in the cargo compartment 902 instead of sensors 301.

[0077] Sensor 301A is an ultraviolet-based point sensor that senses the intensity of ultraviolet light and activates when the change in ultraviolet light intensity exceeds a predetermined change W1. Thus, in this modified example, the difference from the aforementioned structure of sensor 301 that uses a smoke sensor 800 is the use of sensor 301A that senses the intensity of ultraviolet light. Simultaneously, the structure of the actuation device in control system 101B also differs from the structure of actuation device 20 in control system 101.

[0078] More specifically, in the control system 101 of the above embodiment, the actuation device 20 emits smoke 800 as a process for actuating the sensor 301 (see [reference]). Figure 6 On the other hand, in the control system 101B of this modified example, the actuation device generates ultraviolet light as a process for activating the sensor 301A. More specifically, in this modified example, an ultraviolet LED (Light Emitting Diode) lamp that irradiates light including ultraviolet light is used as the actuation device. Specifically, ultraviolet light including ultraviolet light is irradiated from the ultraviolet LED lamp so that the change in intensity of the ultraviolet light sensed by the sensor 301A becomes a predetermined change amount W1 or more, which is a second change amount.

[0079] According to the control system 101B, ultraviolet light is emitted from the actuation device via the control device 30. Since ultraviolet light travels in a straight line, the emitted ultraviolet light is repeatedly reflected between itself and surrounding objects as it enters the sensing range of the sensor 301A. As a result, the change in the intensity of the ultraviolet light sensed by the sensor 301A becomes a change of W1 or more. Consequently, the sensor 301A can be activated. Thus, in this modified example, the sensor 301A can be activated without generating a flame via the actuation device.

[0080] With the control system 101B configured in this way, the effects corresponding to those described in the above embodiments can also be obtained. Therefore, according to the control system 101B, existing automatic fire reporting equipment can be used to reduce the risk of fire.

[0081] In this modified example, the control system 101B differs from the control system 101 of the above-described embodiment in the configuration of the housing 70. Specifically, in the control system 101B, the housing 70 is configured such that a portion of the housing 70 protrudes outward from the periphery of the bottom surface 200a of the vehicle 200. Therefore, compared to a configuration where the housing is in contact with the portion of the bottom surface 200a located directly below the battery 201, the sensor 301A can more reliably detect ultraviolet light emitted from the actuating device.

[0082] Furthermore, in the above description, the sensor 301A was illustrated using an example of a structure where an ultraviolet-type point sensor is mounted on the ceiling 902a. However, it is not limited to this. The sensor 301A can also be an infrared-type point sensor that senses the intensity of infrared light and activates when the change in the intensity of the infrared light becomes a predetermined second change amount W2 or higher. In this case, the activation device can be configured to emit infrared light instead of ultraviolet light. Specifically, light including infrared light is irradiated from an infrared LED or laser diode to cause the change in the intensity of the infrared light sensed by the sensor 301A to become a predetermined change amount W2 or higher. Even with such a structure, the sensor 301A can be activated by the activation device without generating a flame.

[0083] (Third variation) In this modified example, a structure is described in which a sensor constituting the control system detects the internal pressure of the vehicle 200 instead of detecting the temperature of the vehicle 200 as its state. In this configuration, a known pressure sensor can be used as the sensor.

[0084] When the battery 201 heats up, the air inside the vehicle 200 is heated due to the heat from the battery 201. When the air is heated, the internal pressure of the vehicle 200 increases. In this modified example, by using a sensor to detect the increase in internal pressure of the vehicle 200, abnormal heating of the battery 201 can be detected.

[0085] In this modified example, the control device determines whether the pressure change of the internal pressure of the vehicle 200 is greater than or equal to a predetermined first change amount W3. If the pressure change of the internal pressure of the vehicle 200 is determined to be greater than or equal to W3, the control device, as in the above embodiment, activates the alarm device 40 to continuously generate sound and light. Furthermore, the control device activates the actuation device 20 at the aforementioned timing (a certain period of time elapsed after the activation of the alarm device 40), thereby emitting smoke from the actuation device 20.

[0086] With this control system configuration, the effects corresponding to those described in the above embodiments can be obtained. Therefore, the control system according to this modification can reduce the risk of fire by using existing automatic fire reporting equipment.

[0087] (Fourth variation) In this modified example, a structure is described in which a sensor constituting the control system detects infrared radiation emitted from the vehicle 200 instead of detecting the temperature of the vehicle 200 as a state of the vehicle 200. In this configuration, a known infrared sensor can be used as the sensor.

[0088] When the battery 201 heats up, heat is transferred from the battery 201 to the vehicle body 200, thereby heating the bottom surface 200a of a designated portion of the vehicle body. Due to the heating of the bottom surface 200a, the intensity of the infrared radiation emitted from the bottom surface 200a increases. In this modified example, abnormal heating of the battery 201 can be detected by detecting the intensity of this infrared radiation using a sensor.

[0089] In this modified example, the control device determines whether the intensity change of the infrared radiation generated from the vehicle 200 is a predetermined change amount W4 or more, which is considered a first change amount. If it is determined that the intensity change of the infrared radiation generated from the vehicle 200 is W4 or more, the alarm device 40 is activated to continuously generate sound and light, similar to the embodiment described above. Furthermore, the control device activates the actuation device 20 at the aforementioned timing, causing smoke to be emitted from the actuation device 20.

[0090] With this control system configuration, the effects corresponding to those described in the above embodiments can be obtained. Therefore, the control system according to this modification can reduce the risk of fire by using existing automatic fire reporting equipment.

[0091] Furthermore, in the above description, an infrared sensor was used as an example. However, it is not limited to this. A sensor that detects the intensity of ultraviolet radiation emitted from the vehicle 200 can also be used. In this case, the control device determines whether the change in intensity of the ultraviolet radiation emitted from the vehicle 200 is a predetermined change amount W5 or more. If it is determined that the change in intensity of the ultraviolet radiation emitted from the vehicle 200 is W5 or more, the alarm device 40 is activated to continuously generate sound and light, as described above. Furthermore, the control device activates the actuation device 20 at the aforementioned timing, causing smoke to be emitted from the actuation device 20. Even with this structure, the effects corresponding to those described in the above embodiment can be obtained.

[0092] Alternatively, a sensor combining an infrared detector and an ultraviolet detector can be used. In this case, the two parts can complement each other while detecting the state of the vehicle 200. Therefore, it is possible to prevent the detection of changes in the state of the vehicle 200 from being missed.

[0093] (Fifth variation) In this modified example, a structure is described in which a sensor constituting the control system detects the deformation of the vehicle 200 instead of detecting the temperature of the vehicle 200 as its state. Specifically, the sensor in this modified example detects the deformation of the bottom surface 200a of the vehicle 200. In this configuration, a known strain sensor can be used as the sensor.

[0094] When the battery 201 heats up, heat is transferred from the battery 201 to the vehicle body 200, thereby causing thermal deformation on the bottom surface 200a of a designated part of the vehicle body. In this modification, abnormal heating of the battery 201 can be detected by detecting the increased deformation of the bottom surface 200a due to the heating of the battery 201 using a sensor.

[0095] In this modified example, the control device determines whether the deformation change of the motor vehicle 200 is greater than or equal to a predetermined first deformation change W6. If the deformation change of the motor vehicle 200 is determined to be greater than or equal to W6, the alarm device 40 is activated to continuously generate sound and light, similar to the embodiment described above. Furthermore, the control device activates the actuation device 20 at the aforementioned timing, thereby emitting smoke from the actuation device 20.

[0096] With this control system configuration, the effects corresponding to those described in the above embodiments can be obtained. Therefore, the control system according to this modification can reduce the risk of fire by using existing automatic fire reporting equipment.

[0097] (Sixth variation) In this modified example, a structure is described in which a sensor constituting the control system detects the appearance of the vehicle 200 as image data instead of detecting the temperature of the vehicle 200 as its state. Here, the appearance of the vehicle 200 refers not only to the appearance of the vehicle 200 itself, but also to the appearance of the vehicle 200 and its surrounding space.

[0098] The sensor in this modified example detects the appearance of the bottom surface 200a of the motor vehicle 200 and its surrounding space as image data. A known camera can be used as the sensor structure for this purpose.

[0099] Furthermore, in the control system of this modified example, similar to the control system 101A of the first modified example of Embodiment 1 described above, the frame 70A is placed on the floor 902b of the cargo compartment 902, which is located directly below the battery 201 in the bottom surface 200a of the motor vehicle 200.

[0100] When smoke is generated from battery 201 due to heat, the smoke diffuses into the space surrounding bottom surface 200a. In this modified example, the control device sets a predetermined condition that smoke is reflected in an image represented by image data. The control device determines whether smoke is reflected in the image. If smoke is determined to be reflected, as in the above embodiment, the control device activates alarm device 40 to continuously generate sound and light. Furthermore, the control device activates actuation device 20 at the aforementioned timing, causing smoke to be emitted from actuation device 20.

[0101] With this control system configuration, the effects corresponding to those described in the above embodiments can be obtained. Therefore, the control system according to this modification can reduce the risk of fire by using existing automatic fire reporting equipment.

[0102] Furthermore, in the above description, an example of a sensor that detects the appearance of the bottom surface 200a of the vehicle 200 and its surrounding space as image data was used. However, this is not the only limitation. For example, a sensor that detects the appearance of the top surface of the vehicle 200 and its surrounding space can also be used as the sensor.

[0103] Alternatively, a sensor combining the portion that detects the appearance of the vehicle 200 as image data, the portion that detects infrared light, and / or the portion that detects ultraviolet light, as described above, can be used as a sensor. In this case, these portions can detect the state of the vehicle 200 while complementing each other. Therefore, it is possible to prevent the detection of changes in the state of the vehicle 200 from being missed.

[0104] [Implementation Method 2] Figure 9This is a diagram illustrating the hardware structure of each device constituting the control system of Embodiment 2. Figure 10 It is used to explain in Figure 9 The flowchart shows the processing flow executed in the control system. Figure 11 This is a schematic diagram of the cargo hold used to illustrate the operating state of the actuation device in this embodiment.

[0105] The following is for reference Figures 9 to 11 The control system 102, the fire hazard reporting system equipped with the control system 102, and the control method of this embodiment will be described. In this embodiment, the control system 102 is used instead of the control system 101.

[0106] In the control system 101 of embodiment 1, such as Figure 4 As shown, various devices are housed within a housing 70. In contrast, in the control system 102 of this embodiment, as... Figures 9 to 11 As shown, the devices are distributed and built into the first frame 71 and the second frame 72. Thus, in this embodiment, the control system 102 is constituted by the first device (first unit) and the second device (second unit). In this respect, the control system 102 of this embodiment differs from the control system 101 of Embodiment 1.

[0107] Specifically, in this embodiment, a sensor 10, a control device 30, an alarm device 40, a power supply 50, and a first communication interface 61 are built into a first frame 71, which is approximately cuboid in shape. An actuating device 20, a power supply 50A, and a second communication interface 62 are built into a second frame 72, which is also approximately cuboid in shape. The first interface 61 and the second interface 62 are configured to transmit and receive signals wirelessly. The power supply 50A supplies power to the actuating device 20 and the second interface 62. Furthermore, the communication between the first interface 61 and the second interface 62 is not limited to wireless communication; it can also be wired communication.

[0108] The first frame 71, like the frame 70 in Embodiment 1, is disposed in contact with the portion of the bottom surface 200a of the vehicle 200 located near (more specifically, directly below) the battery 201. The second frame 72 is disposed around the sensor 301. Specifically, the second frame 72 is placed on the floor 902b located below the sensor 301.

[0109] like Figure 10 As shown, the processing flow executed in control system 102 is the same as the processing flow executed in control system 101 of Embodiment 1 (see reference). Figure 5 The difference is that there are steps S11 and S12 between steps S3 and S4.

[0110] Specifically, if in step S3 it is determined that the surface temperature is above the set temperature V1 (the case where "yes" is indicated in step S3), the control device 30 activates the alarm device 40 in step S4, continuously generating sound and light (typically flashing). This reports the occurrence of an anomaly to the surrounding environment. After a certain period of time has elapsed since the alarm device 40 was activated, in step 11, a control command Q is sent to the actuation device 20 via the first interface 61. The actuation device 20 receives the control command Q via the second interface 62 in step S12.

[0111] In step S5, based on the control command Q received by the actuating device 20, the actuating device 20 emits smoke 800. Thus, in step S5, the control device 30 actuates the actuating device 20 according to the remote command, emitting smoke 800 from the actuating device 20 (specifically, the smoke generator). Furthermore, the processing in step S4 can be performed simultaneously with the processing in step S5, or it can be performed after the processing in step S5.

[0112] With the control system 102 configured in this way, the effects corresponding to those described in Embodiment 1 above can also be obtained. Therefore, according to the control system 102, the risk of fire can be reduced by using existing automatic fire reporting equipment.

[0113] In the control system 102, smoke 800 generated by the actuation device 20 is ejected below the sensor 301. Therefore, by using the control system 102, the sensor 301 can more reliably detect the smoke 800 ejected from the actuation device 20.

[0114] Furthermore, in this embodiment, the case where the first frame 71 is arranged in contact with the bottom surface 200a of the vehicle 200 is illustrated. However, the first frame 71 may also be arranged nearby without contacting the vehicle 200, similar to the frame 70A in the control system 101A of the first variant of Embodiment 1. That is, the first frame 71 may also be placed on the floor 902b of the cargo compartment 902, which is located directly below the battery 201 on the bottom surface 200a of the vehicle 200.

[0115] In this embodiment, the control device 30 is described as being built into the first frame 71, but the control device 30 can also be built into the second frame 72. That is, in the control system 102, the sensor 10, the power supply 50, and the first interface 61 can be built into the first frame 71, and the control device 30, the actuation device 20, the power supply 50A, and the second interface 62 can be built into the second frame 72.

[0116] In this configuration, sensor 10 sends temperature information R, indicating the surface temperature of the bottom surface 200a detected by sensor 10, to control device 30 via first interface 61. Control device 30 receives temperature information R via second interface 62, and if it determines that the surface temperature indicated by temperature information R is above a set temperature V1, it activates actuation device 20 to emit smoke 800. Even with this configuration, the same effect as with a configuration where control device 30 is integrated into the first frame 71 can be achieved.

[0117] <Variation Example> (First variation) In this modified example, it is described that the automatic fire reporting device 300 has a structure in which a heat sensor 301B is configured to replace the smoke sensor 301. Figure 12 This is a schematic diagram of a motor vehicle with a control system of the first modified example of this embodiment, viewed from the front side. Figure 13 This is a schematic front view of the operating device of this modified example. Figure 14 This is a schematic bottom view of the operating device of this modified example. Hereinafter, refer to these... Figures 12 to 14 The control system 102A of the first modified example of Embodiment 2 will be described.

[0118] like Figures 12 to 14 As shown, in this modified example, the control system 102A includes a second housing 72A instead of the second housing 72. Within the second housing 72A, an actuating device 20A is built in place of the actuating device 20. Furthermore, in the following example, it is assumed that the control device 30 is built into the first housing 71.

[0119] The automatic fire reporting device 300 has multiple sensors 301B and a receiver 302. Specifically, sensors 301B are provided in the cargo compartment 902 instead of sensors 301.

[0120] Sensor 301B is a so-called differential point-type sensor that activates when the internal pressure of its air chamber exceeds a set pressure. An air chamber is located inside the differential point-type sensor. A diaphragm and a contact are located within this air chamber. In sensor 301B, as the internal pressure of the air chamber increases, the diaphragm deforms. Due to this deformation, the contact closes. When the contact closes, sensor 301B activates.

[0121] Thus, in this modified example, the difference from the structure of the sensor 301 for sensing smoke 800 described in the embodiment and the ultraviolet or infrared dot type sensor 301A described in the modified example of embodiment 1 is that a differential dot type sensor 301B is used.

[0122] As described above, since the sensor 301B is different from the sensor 301, the structure of the actuator 20A and the configuration of the second frame 72A in the control system 102A are different from the structure of the actuator 20 and the configuration of the second frame 72 in the control system 102.

[0123] More specifically, in the control system 102 of the above-described embodiment 2, the actuation device 20 emits smoke 800 as a process for activating the sensor 301 (see [reference]). Figure 11 On the other hand, in the control system 102A of this modified example, the actuation device 20A applies pressure to the air chamber of the sensor 301B from the outside as a process for actuating the sensor 301B. In this modified example, the actuation device 20A is an actuation device having an actuator 21 configured to reciprocate in the up-down direction.

[0124] The second frame 72A, including the built-in motion device 20A, has a gripping part 72a consisting of a pair of arm-shaped portions. The gripping part 72a grips the sensor 301B. Thus, the second frame 72A and the sensor 301B are arranged in contact.

[0125] In the control system 102A configured in this way, the actuation device 20A drives the actuator 21 based on the control command Q received via the second interface 62. Driven by the actuator 21, the outer wall of the sensor 301B, which defines a portion of the air chamber, is pressed by the actuator 21. When the outer wall is pressed, the internal pressure of the air chamber increases. Specifically, the actuation device 20A actuates the actuator 21 to raise the internal pressure of the air chamber to a set pressure or higher. As a result, the sensor 301B actuates. Even with this structure, the sensor 301B can be actuated by the actuation device 20A without generating heat.

[0126] With the control system 102A configured in this way, the effects corresponding to those described in embodiments 1 and 2 above can also be obtained. Therefore, according to the control system 102A, the risk of fire can be reduced by using existing automatic fire reporting equipment.

[0127] In this modified example, the case where the actuation device 20A has an actuator 21 has been described, but the actuation device 20A is not limited to having an actuator 21. For example, the actuation device 20A may also have a servo motor and an elastic component such as a spring. In this case, the elastic component can be pressed against the outer wall of the sensor 301B by the driving force of the servo motor. Alternatively, the actuation device 20A may also have a gas generator. In this case, by operating the gas generator directly below the sensor 301B, the internal pressure of the air chamber can be increased. Alternatively, the actuation device 20A may also have gunpowder. In this case, by detonating the gunpowder directly below the sensor 301B, the internal pressure of the air chamber can be increased.

[0128] (Second variation) In this modified example, it is also shown that the automatic fire reporting device 300 has a structure configured as a heat sensor. Figure 15 This is a schematic front view of the operating device of the second variation of this embodiment. Figure 16 This is a schematic bottom view of the operating device in this modified example. Hereinafter, refer to... Figure 15 and Figure 16 The control system 102B of this modified example will be described.

[0129] like Figure 15 and Figure 16 As shown, in this modified example, the control system 102B includes a second housing 72B instead of the second housing 72. Within the second housing 72B, an actuating device 20B is built in place of the actuating device 20. Furthermore, in the following example, it is assumed that the control device 30 is built into the first housing 71.

[0130] The automatic fire reporting device 300 has multiple sensors 301C and a receiver 302. Specifically, sensors 301C are provided in the cargo compartment 902 instead of sensors 301.

[0131] Sensor 301C is a thermostatic point-type sensor that operates when the ambient temperature of sensor 301C reaches or exceeds a set temperature V2, which serves as a second temperature. The thermostatic point-type sensor includes a heating plate, a circular bimetallic element, and contacts. In sensor 301C, due to the rise in temperature of the heating plate, the circular bimetallic element deforms or reverses. This deformation or reversal closes the contacts. When the contacts are closed, the sensor operates.

[0132] As described above, since the sensor 301C differs from the sensor 301, the structure of the actuator 20B and the configuration of the second frame 72B in the control system 102B differ from the structure of the actuator 20 and the configuration of the second frame 72 in the control system 102. Furthermore, since the configuration of the second frame 72B is the same as that of the second frame 72A in the first variant of this embodiment, its description will not be repeated.

[0133] More specifically, in the control system 102 of Embodiment 2, the actuation device 20 emits smoke 800 as a process for actuating the sensor 301 (see [reference]). Figure 11 On the other hand, in the control system 102B of this modified example, the actuation device 20B generates heat as a process for activating the sensor 301C. More specifically, the actuation device 20B has a nickel-chromium alloy wire 22. The actuation device 20B generates heat by heating the nickel-chromium alloy wire 22 to red-hot, thereby raising the ambient temperature of the sensor 301C to a set temperature V2 or higher.

[0134] In the control system 102B configured in this way, the actuation device 20B, upon receiving a control command Q via the second interface 62, heats the nickel-chromium alloy wire 22 to a red-hot state. When the ambient temperature of the sensor 301C reaches or exceeds a set temperature V2 due to the red-hot nickel-chromium alloy wire 22, the temperature of the heated plate rises. As the temperature of the heated plate rises, the circular bimetallic element reverses, etc. Due to this reversal, the sensor 301C actuates. Even with this structure, the actuation device 20B can actuate the sensor 301C without generating heat caused by the flame.

[0135] With the control system 102B configured in this way, the effects corresponding to those described in embodiments 1 and 2 can also be obtained. Therefore, according to the control system 102B, the risk of fire can be reduced by using existing automatic fire reporting equipment.

[0136] Furthermore, in this modified example, the case where the actuating device 20B has a nickel-chromium alloy wire 22 has been described as an example, but the actuating device 20B is not limited to having a nickel-chromium alloy wire 22. For example, the actuating device 20B may also have a Peltier element or gunpowder. In this case, heating by the Peltier element or gunpowder can activate the sensor 301C.

[0137] (Third variation) In this modified example, the automatic fire reporting device 300 is described to have a structure in which a sensor 301D configured as a detection signal replaces the sensor 301 that detects smoke. Figure 17 This is a diagram illustrating the hardware structure of each device in the control system 102C constituting the third variation of this embodiment. Figure 18This is a schematic diagram of the cargo hold used to illustrate the operational state of the actuating device in this modification example. Hereinafter, reference will be made to these... Figure 17 and Figure 18 The control system 102C of the third variation of Embodiment 2 will be described.

[0138] like Figure 17 and Figure 18 As shown, in this modified example, the control system 102C includes a first frame 71C instead of the first frame 71. A sensor 10C and a first interface 61 are built into the first frame 71C. The first frame 71C, the sensor 10C, and the first interface 61 constitute an RFID (Radio Frequency Identification) tag equipped with a temperature sensor.

[0139] Sensor 10C corresponds to the temperature detection portion of the RFID tag. For example, a contact temperature sensor may be used as sensor 10C. First interface 61 corresponds to the portion of the RFID tag that transmits the temperature information detected by sensor 10C as a signal via wireless communication or receives control commands Q1 sent from the control device 30C (described later) via wireless communication. First housing 71 corresponds to a protective component in the RFID tag that protects sensor 10C and first interface 61.

[0140] The RFID tag thus constructed is installed on the bottom surface 200a of the vehicle 200. The sensor 10C can then detect the surface temperature of the bottom surface 200a. Furthermore, multiple RFID tags can be installed on the bottom surface 200a as needed.

[0141] Additionally, the RFID tag can be placed near the vehicle body of the motor vehicle 200 or near the part housing the battery 201. Considering ease of installation, the RFID tag is more preferably placed on the fastening straps that secure the floor 902b of the cargo compartment 902 and the motor vehicle 200 together. Furthermore, in these cases, a non-contact temperature sensor is preferably used as the sensor 10C, for example.

[0142] The control system 102C has a second housing 72C instead of the second housing 72. The second housing 72C houses the actuating device 20C, the control device 30C, the power supply 50C, and the second interface 62. The second housing 72C is configured adjacent to the third interface 63, which will be described later.

[0143] The control system 102C also includes a third interface 63 for communication. The third interface 63 is a repeater that relays the transmission and reception of signals between the first interface 61 and the second interface 62, or relays the transmission of signals from the second interface 62 to the sensor 301D. The third interface 63 is, for example, installed on the ceiling 902a of the cargo hold 902. However, the configuration of the third interface 63 is not particularly limited to this; it can also be installed on the wall of the cargo hold 902, or on the floor 902b of the cargo hold 902.

[0144] The automatic fire reporting device 300 has multiple sensors 301D and a receiver 302. Specifically, sensors 301D are provided in the cargo compartment 902 instead of sensors 301.

[0145] The sensor 301D operates by receiving a predetermined signal. With the use of this sensor 301D, the structure of the actuator 20C in the control system 102C differs from the structure of the actuator 20 in the control system 102.

[0146] More specifically, in the control system 102 of the above-described embodiment 2, the actuation device 20 emits smoke 800 as a process for activating the sensor 301 (see [reference]). Figure 11 On the other hand, in the control system 102C of this modified example, the actuation device 20C sends a predetermined signal P1 to the sensor 301D as a process for activating the sensor 301D. In this modified example, the actuation device 20C uses a transmitter configured to send the signal P1 to the sensor 301D via wireless or wired communication.

[0147] In the control system 102C configured in this way, the control device 30C acquires temperature information detected by the sensor 10C from the sensor 10C according to a predetermined first cycle (e.g., every 30 seconds). When the surface temperature of the bottom surface 200a of the vehicle 200 detected by the sensor 10C becomes higher than or equal to a set temperature V11, the control device 30C sends a control command Q1 to the sensor 10C to change the aforementioned first cycle to a predetermined second cycle (e.g., every 10 seconds) that is shorter. Thereafter, the control device 30C acquires the temperature information detected by the sensor 10C from the sensor 10C according to each second cycle. Furthermore, the set temperature V11 is set to a predetermined temperature lower than the aforementioned set temperature V1.

[0148] When the surface temperature of the bottom surface 200a of the vehicle 200, as detected by the sensor 10C, becomes higher than the set temperature V1, the control device 30C sends a signal P1 from the actuation device 20C to the sensor 301D. As a result, the sensor 301D is activated.

[0149] With the control system 102C configured in this way, the effects corresponding to those described in embodiments 1 and 2 above can be obtained. Therefore, according to the control system 102C, the risk of fire can be reduced by using existing automatic fire reporting equipment.

[0150] Furthermore, as described above, the control system 102 is configured such that, when the state of the vehicle 200 detected by the sensor 10C meets predetermined conditions, the control device 30C can change the period at which it obtains information from the sensor 10C from a first period to a shorter second period. This allows for more focused monitoring of the vehicle 200's state in situations where the risk of fire is relatively high.

[0151] In this modified example, the control system 102C is described with the third interface 63 as an example. However, if the control system 102C can communicate directly between the first interface 61 and the second interface 62 and can send signals directly from the second interface 62 to the sensor 301D, the control system 102C may not necessarily have the third interface 63.

[0152] [Implementation Method 3] Figure 19 This is a diagram illustrating the hardware structure of each device constituting the control system of Embodiment 3. Figure 20 This is a schematic diagram of the cargo hold used to illustrate the state of operation of the actuation device in Embodiment 3.

[0153] The following is for reference Figure 19 and Figure 20 The control system 103, the fire hazard reporting system equipped with the control system 103, and the control method of this embodiment will be described. In this embodiment, the control system 103 is used instead of the control system 101. In addition, in this embodiment, the sensor 13 is used instead of the sensor 10.

[0154] In the control system 101 of embodiment 1, such as Figure 6 As shown, sensor 10 detects the state of a motor vehicle 200. In contrast, in the control system 103 of this embodiment, as... Figure 19 and Figure 20 As shown, sensor 13 is configured to detect the state of multiple motor vehicles 200. In this respect, the control system 103 of this embodiment differs from the control system 101 of embodiment 1.

[0155] Specifically, in this embodiment, the frame 70 is disposed on the surface of the column 903 provided in the cargo compartment 902, on the side of the floor 902b. In addition, the position of the frame 70 is not particularly limited to this, and it can be disposed on the surface of the wall of the cargo compartment 902, or on the floor 902b on the portion opposite to the bottom surface 200a of a specific vehicle 200.

[0156] The sensor 13 built into the housing 70 is configured to detect the status of multiple motor vehicles 200. In this embodiment, such a sensor 13 is, for example, a non-contact multi-eye sensor with a built-in non-contact temperature sensor.

[0157] Non-contact multi-eye sensors mainly consist of an array of multiple non-contact temperature sensors (such as thermopile sensors) or a CMOS image sensor, a lens, and a lens holder to hold the lens. Non-contact temperature sensors determine temperature by measuring the infrared radiation emitted from an object.

[0158] As an example, in this embodiment, a non-contact multi-eye sensor is used, comprising an array of 64 non-contact temperature sensors arranged in 8 rows and 8 columns. However, the number and arrangement of the sensors in the non-contact multi-eye sensor are not particularly limited thereto and can be appropriately varied depending on desired viewing angles and other conditions. A wider viewing angle of the non-contact multi-eye sensor allows for a wider measurement range. Therefore, by selecting sensors with a large viewing angle, it is expected that the number of monitorable vehicles 200 per set number can be increased, and the monitoring area can be expanded.

[0159] By using a non-contact multi-eye sensor configured in this way, the surface temperature of the vehicle 200 can be detected separately within the field of view corresponding to each of the multiple non-contact temperature sensors.

[0160] The control device 30 acquires temperature information from the sensor 13, indicating the temperature detected by the sensor 13, according to a predetermined control cycle T. If the temperatures of the multiple motor vehicles 200 detected by the sensor 13 meet predetermined conditions, the control device 30 causes the actuation device 20 to perform a warning process.

[0161] Specifically, when the number of surface temperatures that are above a set temperature V1 among the total 64 surface temperatures of the motor vehicle 200 detected by the sensor 13 becomes a predetermined number or more, the control device 30 generates smoke from the actuation device 20.

[0162] With the control system 103 configured in this way, the effects corresponding to those described in Embodiment 1 above can also be obtained. Therefore, according to the control system 103, the risk of fire can be reduced by using existing automatic fire reporting equipment.

[0163] Furthermore, as described above, when the control system 103 is configured to detect the state of multiple motor vehicles 200 by means of the sensor 13, the setup work of the control system 103 can be saved compared to the case where the state of only one motor vehicle 200 is detected by means of the sensor.

[0164] In addition, in the above embodiment, the following case is used as an example: when the surface temperature of the motor vehicle 200 detected by the sensor 13 becomes above the set temperature V1, the control device 30 generates smoke from the actuation device 20; however, it is not limited to this.

[0165] As an example, the control device 30 may also generate smoke from the actuation device 20 when the temperature difference between the surface temperature of the vehicle 200 detected by the sensor 13 and the ambient temperature (more specifically, the ambient temperature of the cargo compartment 902 on which the vehicle 200 is loaded) becomes above a set temperature.

[0166] Specifically, the surface temperatures of a total of 64 locations on the vehicle 200 detected by sensor 13 can be compared with the ambient temperature. If the number of surface temperatures whose temperature difference with the ambient temperature exceeds a set temperature becomes a predetermined number or more, smoke is generated from the actuation device 20. In this case, the control system 103 needs to include a temperature sensor for measuring the ambient temperature in addition to sensor 13. Alternatively, instead of comparing the surface temperature of the vehicle 200 with the ambient temperature as described above, the surface temperature of the vehicle 200 can be compared with a predetermined temperature.

[0167] Additionally, as another example, the control device 30 may also generate smoke from the actuation device 20 when the change in the surface temperature of the motor vehicle 200 detected by the sensor 13 becomes greater than a predetermined change.

[0168] Specifically, firstly, the control device 30 acquires and stores the surface temperatures of a total of 64 locations on the vehicle 200 detected by the sensor 13 at a certain moment. This "certain moment" could be, for example, the moment after a predetermined time (e.g., 30 minutes) has elapsed since the vehicle 200 was loaded onto the vehicle transport vessel 900.

[0169] Next, the control device 30 acquires temperature information from the sensor 13, showing the surface temperatures of a total of 64 locations on the vehicle 200 detected by the sensor 13, according to a predetermined control cycle T. Then, the control device 30 calculates the change in each of these surface temperatures compared to the change in the surface temperatures of the total 64 locations on the vehicle 200 at a given time. If the number of changes among these 64 calculated changes that are greater than or equal to a predetermined number becomes more than a predetermined number, smoke may be generated from the actuation device 20.
