[0002] In the current automated terminals, unmanned driving of trailers and automatic charging of unmanned vehicles have been realized. Since the automated charging station is located in an unmanned automated yard, once the charging pile or the battery of the Intelligent Guided Vehicle (IGV) in the charging station catches fire, if the personnel cannot find it in time, the fire will spread to other guided vehicles in the charging station, causing the scope of the fire to expand.

[0003] The existing emergency plan for fires in automated charging stations is usually: off-site personnel discover the fire in the charging station through video surveillance, or discover the fire in the charging station through abnormalities in the charging pile or the charging guide transport vehicle. Then the equipment repair personnel are notified, and the repair personnel remotely take over the guide transport vehicle in the charging station, terminate its charging task, and remotely tow the vehicle to a nearby parking location. However, this method is not efficient and can only remotely control one vehicle at a time. Summary of the invention

DETAILED DESCRIPTION

[0042] The drawings of the present invention are only for illustrative purposes and should not be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; it is understandable to those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted.

[0043] The present application embodiment provides a fire emergency handling device for guiding an automated charging station 1 for a transport vehicle, such as Figure 1 , the device comprises:

[0044] An automated charging station 1, which can charge multiple guided transport vehicles 2 at the same time, and is equipped with a thermal imaging camera 4;

[0045] An automated charging station fire intelligent monitoring system 6, wherein the automated charging station fire intelligent monitoring system 6 is connected to the thermal imaging camera 4, and the parameters acquired by the thermal imaging camera 4 are transmitted to the automated charging station fire intelligent monitoring system 6, and the automated charging station fire intelligent monitoring system 6 generates an alarm according to the parameters;

[0046] The guided transport vehicle dispatching system 7 obtains information of the guided transport vehicle 2 associated with the automated charging station 1, wherein the guided transport vehicle 2 associated with the automated charging station 1 includes the IGV 22 being charged, the IGV 23 that has completed charging but has not left, and the IGV 24 on the way to charging, and triggers concurrent work tasks of the associated guided transport vehicle 2;

[0047] The equipment control interface system 8 is connected to the guide transport vehicle scheduling system 7 to receive the work tasks issued by the guide transport vehicle scheduling system 7;

[0048] The vehicle management system 9 is connected to the equipment control interface system 8 and is used for planning, issuing movement instructions and monitoring the real-time status of the transport vehicle 2 .

[0049] At the automated terminal, the guided transport vehicle 2 is mainly driven by electric energy. Since the guided transport vehicles 2 at the automated terminal are all self-driving and have high work intensity, the replenishment of electric energy is a common behavior, and an automated charging station 1 is set up at the automated terminal. In order to improve work efficiency, battery technology is updated very quickly, and most charging methods adopt fast charging mode. For example, the common lithium battery is composed of chemical components. When overcharged, a large amount of heat accumulates inside the battery, which may cause a short circuit, leading to an explosion or fire. In addition, if there is external force damage, such as squeezing or puncture, it will directly damage the battery structure, causing a short circuit and fire. Especially in the port environment, the guided transport vehicles 2 are parked densely and the wind speed at the seaside is also relatively high. If a fire occurs during the charging process, the fire will spread rapidly, and the guided transport vehicle 2 battery can be completely burned within a few minutes, which will cause great losses to the port.

[0050] In the prior art, if a fire occurs, it is usually extinguished based on fire prevention equipment at the scene, such as a dry powder fire extinguisher placed at the charging station. Then the corresponding person in charge will manually extinguish the fire, and then wait for firefighters to professionally extinguish the fire. This fire extinguishing process is inefficient, especially the spread of the fire cannot be controlled in time.

[0051] To solve the above problems, the technical solution proposed in this embodiment includes:

[0052] Automated charging station 1, in order to solve the charging problem of guided transport vehicle 2, this charging station can provide charging services for multiple guided transport vehicles 2 at the same time, and the charging process is an automated process. The guided transport vehicle 2 selects the nearest automated charging station 1 for charging according to its own power. If the power is less than 20%, it will confirm with the vehicle management system 9 whether to charge and where the charging location is. After confirmation by the vehicle management system 9, the guided transport vehicle 2 drives to the automated charging station 1 and parks at the designated charging pile 3 for charging. When charging is completed, the automated charging station 1 will automatically disconnect the guided transport vehicle 2 from the charging pile 3. In addition to automatic charging, manual intervention is also possible. The vehicle management system 9 monitors all guided transport vehicles 2, comprehensively evaluates power, work tasks, charging arrangements and other factors, and can charge in advance if the power is not less than 20%.

[0053] In the automated charging station 1, a thermal imaging camera 4 is installed, which can detect the monitoring screen in real time. The temperature, fire, and smoke in the screen can all be monitored. The thermal imaging camera 4 is installed in the best visual position and can monitor the entire charging area. In order to prevent the power and transmission link required by the thermal imaging camera 4 from being destroyed in the event of a fire, the power and transmission required by the thermal imaging camera 4 are independent of the automated charging station 1. In this way, even if the automated charging station 1 is powered off or the weak current line is destroyed, it will not affect the continued operation of the thermal imaging camera 4.

[0054] In this embodiment, the fire intelligent monitoring system 6 of the automated charging station is connected to the thermal imaging camera 4. The thermal imaging camera 4 transmits all the detected images to the fire intelligent monitoring system 6 of the automated charging station. The fire intelligent monitoring system 6 of the automated charging station determines whether a fire has occurred in the automated charging station 1 based on the monitoring data. If the temperature exceeds the set threshold or fire or smoke is detected, the fire intelligent monitoring system 6 of the automated charging station will generate an alarm event. Specifically, when the temperature exceeds 130 degrees, it is determined that a fire has been found. This embodiment also provides

[0055] Alarm module, the alarm module includes sound warning, warning message sending, and warning cancellation. Through the alarm module, a warning can be issued externally. When the detected temperature reaches the normal range and there is no fire, electricity, or smoke alarm, the warning can also be cancelled.

[0056] Specifically, the present embodiment further includes a fire extinguishing module installed in the automated charging station 1 and the dedicated fire extinguishing parking space 5. When the automated charging station fire intelligent monitoring system 6 determines that a fire has occurred, the fire extinguishing module is automatically triggered. For example, a fire extinguishing device can be suspended above the automated charging station 1, and some isolation devices can also be provided.

[0057] In this embodiment, the guided transport vehicle scheduling system 7 can schedule and manage the global guided transport vehicle 2 and allocate the guided transport vehicle 2 according to demand. At the same time, it is connected to the fire intelligent monitoring system 6 of the automated charging station, receives the fire information transmitted by the fire intelligent monitoring system 6 of the automated charging station, allocates corresponding tasks to the guided transport vehicle 2, and sends these tasks to the equipment control interface system 8. The equipment control interface system 8 is an intermediate scheduling module, which can generate corresponding tasks (ORDER) for the guided transport vehicle 2 and the rail crane according to the messages sent by other scheduling modules and interface modules, and then send the ORDER to the corresponding equipment management system. For example, when receiving the guided transport vehicle 2 task message sent by the guided transport vehicle 2 scheduling module, the equipment control interface system 8 will generate the corresponding AHT_ORDER according to the content of the message, and then send the AHT_ORDER to the vehicle management system 9. The vehicle management system 9 is a system for managing all intelligent guided vehicles in the automated terminal, which mainly plans and issues motion instructions and monitors the real-time status of all vehicles, such as the communication status between the vehicle and the system, the power of the guided transport vehicle 2, the location of the guided transport vehicle 2, and the execution status of the guided transport vehicle 2 instruction. The vehicle management system 9 also has one of the functions of implementing the instructions issued by the dispatcher and planning the path for the task.

[0058] Specifically, the present embodiment also includes a special fire-fighting parking space 5, which is only used to park the guide transport vehicle 2 affected by the fire. As mentioned above, the fire intelligent monitoring system 6 of the automated charging station detects the fire, and the guide transport vehicle dispatching system 7 allocates the associated guide transport vehicle 2 to leave the fire area. The vehicle management system 9 then plans its escape route and drives it to the designated location. Because after the battery catches fire, the fire will spread very quickly, often burning or exploding the entire battery within a few minutes. In order to avoid further spread of the fire, the guide transport vehicle 2 with the most serious fire is driven to the special fire-fighting parking space 5. After the battery catches fire, the kinetic energy of the guide transport vehicle 2 will be lost, resulting in the inability to move. A backup power supply can be set on the guide transport vehicle 2 to be used to leave the fire area after the fire.

[0059] The present application also provides a method for handling fire emergencies in an automated charging station 1 for a guided transport vehicle, such as Figure 2 , the method comprising:

[0060] S100: Monitoring fire conditions at the automated charging station 1 by means of a thermal imaging camera 4;

[0061] S102: Disconnect the power supply of the automated charging station 1;

[0062] S104: triggering a fire alarm;

[0063] S106: Acquire information of the guide transport vehicle 2 associated with the automated charging station 1;

[0064] S108: Generate a concurrent fire dispatch plan;

[0065] S110: Guide the transport vehicle 2 away from the fire location.

[0066] This method can quickly control the fire, disengage the IGV 21 that has caught fire and the guide transport vehicle 2 that may be affected by the fire, and the disengagement action is performed concurrently, that is, multiple guide transport vehicles 2 are executed to leave the fire area at the same time. Since this field belongs to an automated terminal, each guide transport vehicle 2 can move automatically and quickly. In this way, the impact range of the IGV 21 that has caught fire is reduced to a minimum, and at the same time, the risks of the guide transport vehicles 2 that may be affected are effectively avoided, such as timely disconnection and departure during charging, timely departure after charging is completed but not yet left, and immediate stop of the guide transport vehicle 2 on the way to charging. After multiple actions are executed concurrently, the fire can be effectively controlled.

[0067] In this embodiment, specifically, monitoring the fire condition of the automated charging station 1 includes:

[0068] The real-time temperature, thermal power and smoke in the area are obtained through the thermal imaging camera 4;

[0069] Rasterize the area;

[0070] Compare with normal charging in the area;

[0071] Determine the location and severity of the fire.

[0072] After the fire area is gridded, the fire position can be quickly located. Combined with the detection of the guide transport vehicle 2 itself, and the information obtained by the thermal imaging camera 4 is compared with the normal state in the area through the automatic charging station fire intelligent monitoring system 6, the specific IGV 21 on fire, the specific charging pile 3 or position on fire can be located. And the severity of the fire can also be defined by monitoring factors such as temperature or impact range. For example, taking temperature as an example, different temperature ranges are set to different levels. Taking the impact range as an example, the size of the grid area affected by the fire, the equipment is different, etc.

[0073] In this embodiment, specifically, a concurrent fire dispatching scheme is included:

[0074] Determine the guide transport vehicles 2 that need to leave the fire location, wherein the guide transport vehicles 2 that need to leave the fire location include the IGV 22 that is being charged, the IGV 23 that has completed charging but has not left, and the IGV 24 that is on the way to charging;

[0075] At the same time, the IGV 22 that is charging is disconnected from charging and leaves the fire location, the IGV 23 that has completed charging but has not left is left from the fire location, and the IGV 24 that is on the way to charging is stopped from going.

[0076] First, by monitoring the fire, determine which guided transport vehicles 2 are affected and what the affected range is, so as to determine which guided transport vehicles 2 need to leave the fire and where they are. Then, execute the affected guided transport vehicles 2 to leave, and the execution task is performed concurrently.

[0077] Furthermore, the most seriously affected guided transport vehicle 2 can be moved to a dedicated fire-extinguishing parking space 5, so that the fire source can be cut off more quickly.

[0078] In this embodiment, when the affected guide transport vehicle 2 is to be disengaged, due to the limited space of the charging station, the disengagement task is performed simultaneously without affecting each other, and the route needs to be planned in advance. Furthermore, the order of using the charging piles 3 in the automated charging station 1 is planned to avoid route conflicts when leaving the fire location.

[0079] The present application also provides an embodiment. Specifically, when a fire occurs at the automated charging station 1 for the guided transport vehicle, the thermal imaging camera 4 detects an open flame or smoke, which satisfies the conditions of the linkage event set in the fire intelligent monitoring system of the automated charging station 1, and starts to trigger an alarm event. At the same time, the system generates a message and calls the interface to send it to the dispatching module of the guided transport vehicle 2. The message content is as follows:

[0080] {

[0081] "dataid":"", / / data identifier

[0082] "rechId":"", / / Guide the transport vehicle to the automated charging station No. 1

[0083] "temperatureAlarm":"", / / Temperature alarm signal, value is 1 or 0

[0084] "fireAlarm":"", / / Fire alarm signal, value is 1 or 0

[0085] "smokeAlarm":"", / / smoke alarm signal, value is 1 or 0

[0086] "evacuate":"", / / Vehicle automatic evacuation signal, value is 1 or 0

[0087] }

[0088] After receiving the message, the Guided Transport Vehicle 2 dispatch module will first judge the content of the message. If "evacuate": is "1", it means that the Guided Transport Vehicle 2 in the charging station needs to evacuate. Then the Guided Transport Vehicle 2 dispatch module will obtain the information in the charging station, including the information of the Guided Transport Vehicle 2 that is charging, the Guided Transport Vehicle 2 that has been fully charged but has not left, and the Guided Transport Vehicle 2 that is on its way to charge.

[0089] Get the information of the guide transport vehicle 2 in the charging station and print the log as follows:

[0090] Statistics: RECH01, total: 3, vehicles: [V001, V002, V003], charging: [V001], charging going: [V002], parking: [V003]

[0091] The log shows that vehicle V001 is charging, vehicle V002 is on its way to charge, and vehicle V003 is fully charged but has not yet left the charging station.

[0092] For the guided transport vehicle 2 that is charging, a task termination message and an instruction to go to a nearby parking space are sent to the device control interface system 8; for the guided transport vehicle 2 that is fully charged but has not left, an instruction to go to a nearby parking space is sent to the device control interface system 8; for the guided transport vehicle 2 that is going to charge, a task termination message and an instruction to go to a nearby parking space are sent to the device control interface system 8. The message content is as follows:

[0093] {

[0094] "ahtFleet":"", / / Guide whether transport vehicle 2 is in the fleet

[0095] "batteryState":"", / / Battery status

[0096] "chargingStatus":"", / / Charging status

[0110] "pauseState":"", / / stop state

[0111] "technicalStatus":"", / / Fault status

[0112] "updated":"" / / Record the last updated time

[0113] }

[0114] If "status" = "CANCEL", it means that the leading transport vehicle 2 needs to cancel the current task, and "isdrive": "YES", it means that the current leading transport vehicle 2 needs to be driven away.

[0115] After receiving the message, the device control interface system 8 will perform a logical judgment based on the message content. If "status" = "CANCEL", the device control interface system 8 will cancel the current task of guiding the transport vehicle 2, and the print log is as follows:

[0116] receive AHT_ORDER_CANCEL-null message{"EVENT_TYPE":"AHT_ORDER_CANCEL"} / / Received task cancellation message

[0117] AHT_ORDER_CANCEL-:850826181698650112 / / task message id

[0118] AHT_ORDER 850826181698650112canceled. / / Task canceled

[0119] If "isdrive": "YES", it means that the current guide transport vehicle 2 needs to be driven away from the current position. The equipment control interface system 8 will find a suitable parking space in the yard and generate a task (AHT_ORDER) for the guide transport vehicle 2 to go there. The print log is as follows:

[0120] IGV:V001, Location:RECH01 needs to be driven away,

[0121] IGV V001 triggers empty vehicle dispatch.

[0123] Temporary parking lot configuration is empty

[0124] che:V001, found PK:PARK.BLOCK.CE.L

[0125] After finding the parking space, the device control interface system 8 starts to generate the corresponding AHT_ORDER, for example:

[0126] save ahtorder is:

[0168] After the device control interface system 8 generates AHT_ORDER, the vehicle management system 9 obtains the corresponding task, and then starts to generate AHT_CMD, and sends instructions to the corresponding guide transport vehicle 2, so that the guide transport vehicle 2 starts to plan a path to the destination.

[0169] In some embodiments, specifically, Figure 3 and Figure 4 , the IGV 21 that caught fire caught fire while it was charging. After the thermal imaging camera 4 detected the fire, it started to alarm and sent a related message to the guided transport vehicle 2 scheduling module. After receiving the message, the guided transport vehicle 2 scheduling module began to obtain all the guided transport vehicles 2 information in the automated charging station 1, and found that there were two charging IGVs 22 in the charging station, a guided transport vehicle 2 that had completed charging but had not left, and a guided transport vehicle 2 that was heading to the charging station.

[0170] For the IGV21 on fire and the IGV22 being charged: the guide transport vehicle 2 dispatch will send a task termination message and a drive-off message to the device control interface system 8. After receiving the message, the device control interface system 8 terminates the charging task of the guide transport vehicle 2 and generates a moving task (aht_order) to the parking space. After obtaining the aht_order, the vehicle management system 9 generates the corresponding aht_cmd and sends a command to the guide transport vehicle 2 to evacuate the charging station and go to the appropriate guide transport vehicle 2 parking space. However, the charging IGV22 still stays at the original charging position because the battery has caught fire;

[0171] For IGV23 that has completed charging but has not left: IGV23 that has completed charging but has not left is parked in the charging station and is in a no-task state. The guide transport vehicle 2 dispatcher will send a drive message to the device control interface system 8. After receiving the message, the device control interface system 8 generates a moving task (aht_order) for the guide transport vehicle 2 to go to the parking space. After obtaining the aht_order, the vehicle management system 9 generates the corresponding aht_cmd and sends a command to the guide transport vehicle 2 to evacuate the charging station and go to the appropriate guide transport vehicle 2 parking space;

[0172] For IGV24 on the way to charging: the guide transport vehicle 2 dispatch will send a task termination message and a drive-off message to the device control interface system 8. After receiving the message, the device control interface system 8 terminates the moving task of the guide transport vehicle 2 and generates a moving task (aht_order) to the parking space. After obtaining aht_order, the vehicle management system 9 generates the corresponding aht_cmd and sends a command to the guide transport vehicle 2 to re-plan the path to the appropriate guide transport vehicle 2 parking space, or stay at the original position.

[0173] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation methods of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the claims of the present invention shall be included in the protection scope of the claims of the present invention.
