DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Reference Figure 1 The present application embodiment provides a method for monitoring battery thermal management of sanitation new energy vehicles based on the Internet of Things, including: S1, obtain the real-time temperature of the battery pack built into the sanitation new energy vehicle; S2, when the real-time temperature of the battery pack exceeds the preset temperature, a high temperature warning of the battery pack 1 is issued to the vehicle owner terminal and the fire control center through the Internet of Things, the clamping assembly installed on the sanitation new energy vehicle is controlled to release the battery pack 1, and the flip plate 32 installed on the sanitation new energy vehicle is controlled to rotate downward, so that the released battery pack 1 gradually moves downward from the flip plate 32 to the ground under the action of gravity; S3, after determining that the battery pack 1 has moved to the ground, wirelessly controlling the battery pack 1 to move away from the sanitation new energy vehicle.

[0020] In step S1, the battery pack 1 itself is detected in real time by the temperature sensor above the battery pack 1 placement area, and the detected information is transmitted to the controller. The temperature sensor is installed inside the battery pack shell, and the temperature sensor can be arranged at one or more positions of the battery pack shell. The battery core temperature sensed by multiple temperature sensors is used as the temperature judgment of the battery pack 1 for more accurate judgment.

[0021] When there is one temperature sensor, if the real-time battery pack temperature collected by the temperature sensor exceeds the preset temperature, it is considered that battery pack 1 has a high temperature; when there are two or more temperature sensors, as long as the real-time battery pack temperature collected by one of the temperature sensors exceeds the preset temperature, it is considered that battery pack 1 has a high temperature.

[0022] Among them, the preset temperature set in the embodiment of the present application is a temperature close to combustion.

[0023] In step S2, when it is determined that the battery pack 1 is close to high temperature, the controller of the sanitation new energy vehicle will transmit this information to the owner's mobile phone and the fire control center through the Internet of Things, so that firefighters can rescue in time to avoid causing greater damage. At the same time, transmitting the information to the owner can let the owner know this information and make timely processing. For example, when the owner is driving, he will receive this information, so the owner can make timely preparations to park and quickly leave the sanitation new energy vehicle, thereby ensuring the owner's own life safety.

[0024] For the car owner, when the car owner terminal (such as a mobile phone) receives a high temperature warning message, the car owner can control the third hydraulic device provided on the battery pack 1 which is in the off state and in a high temperature environment to drive the rotating wheel 11 to rotate by operating the terminal, thereby making the battery pack 1 leave the sanitation new energy vehicle.

[0025] Reference Figure 4 In step S2, when it is determined that the battery pack 1 is close to high temperature, the controller controls the hydraulic cylinder of the first hydraulic control device to move and reset through the hydraulic cylinder. When resetting, the hydraulic cylinder can drive the mounting plate 21 to move horizontally. When the mounting plate 21 moves, it can drive the two clamping blocks 22 to move, so that the two clamping blocks 22 can leave the clamping groove 14 provided on the battery pack shell, thereby releasing the battery pack 1. That is, the controller outputs the first hydraulic control instruction to the first hydraulic drive device installed on the sanitation new energy vehicle, and the first hydraulic drive device drives the clamping assembly to move away from the battery pack 1, and the clamping assembly is released from the battery pack 1, thereby releasing the battery pack 1.

[0026] Further, refer to Figure 4 When the clamping mechanism releases the battery pack 1, the controller of the sanitation new energy vehicle can control the rotating rod 31 connected to the second hydraulic control device to rotate, thereby driving the flip plate 32 at the bottom of the battery pack shell to rotate, so that the battery pack 1 can slowly move downward under its own gravity, thereby leaving the battery pack placement cavity inside the sanitation new energy vehicle and contacting the ground. That is, the controller outputs a second hydraulic control instruction to the second hydraulic drive device installed on the sanitation new energy vehicle, and the second hydraulic drive device drives the flip plate 32 to flip downward to form an exit for the battery pack 1 to move out, and the released battery pack 1 gradually moves downward from the flip plate 32 to the ground under the action of gravity.

[0027] In step S3 of the embodiment of the present application, the camera 12 mounted on the battery pack 1 collects images of the surrounding environment of the battery pack 1 in real time to identify whether the battery pack 1 is moved from the battery pack placement cavity to the ground. The camera 12 may be a wide-angle camera.

[0028] In step S3, the rotating wheel 11 is rotated for a certain period of time by remote control, and the battery pack 1 can be separated from the new energy sanitation vehicle at this time, thereby ensuring that the new energy sanitation vehicle will not catch fire.

[0029] Reference Figure 1 In an embodiment of the present application, the method further includes: S4, after determining that the battery pack 1 has moved to the ground, the real-time position of the battery pack 1 acquired by the GPS positioning module on the battery pack 1 and the real-time environment image acquired by the camera 12 on the battery pack 1 are sent to the vehicle owner terminal and the fire control center; S5, according to the position control instruction sent by the vehicle owner terminal, controlling the battery pack 1 to move along the direction specified by the vehicle owner.

[0030] In step S4, the processor 13 on the battery pack 1 uses the Internet of Things to send the real-time position and real-time environmental image of the battery pack 1 to the vehicle owner terminal and the fire control center. Similarly, the position control instruction issued by the vehicle owner terminal is also sent to the processor 13 on the battery pack 1 using the Internet of Things.

[0031] Reference Figure 3 For the car owner, the car owner logs in to the car control APP through the mobile phone, enters the location information inside to view the real-time location of the battery pack 1 (that is, the GPS location information of the battery pack 1), and checks the surrounding environment where the battery pack 1 is moving at this time through the live display to see whether it is in an open state. The user can operate the virtual operation buttons on the car control APP to control the steering and driving of the battery pack 1 to ensure that the battery pack 1 moves to an open area.

[0032] The above method of this embodiment uses the temperature sensor above the battery pack 1 placement area to perform real-time detection of the placed battery pack 1 itself, and transmits the detection information to the controller of the sanitation new energy vehicle itself, and analyzes the detected real-time temperature of the battery pack through the processing unit in the controller to determine whether it is in a high temperature situation; when the processing unit analyzes that the temperature of the battery pack 1 is close to the combustion temperature, it is determined to be in a high temperature situation; when it is determined that the battery pack 1 is in a situation close to high temperature, the controller of the sanitation new energy vehicle will transmit this information to the owner's terminal and the fire control center through the Internet of Things, so that firefighters can rescue in time to avoid causing greater damage. At the same time, transmitting the information to the owner can let the owner know this information and do timely processing; when it is detected that the battery pack 1 is in a high temperature, the controller of the sanitation new energy vehicle will be able to control the hydraulic cylinder of the first hydraulic drive device to move, and reset it through the hydraulic cylinder. When resetting, the hydraulic cylinder will be able to drive the mounting plate 21 to Horizontal movement, when the mounting plate 21 moves, it will be able to drive the two clamping blocks 22 to move, so that the two clamping blocks 22 can leave the clamping grooves 14 provided on the battery pack shell, thereby realizing the release of the battery pack 1; when the clamping mechanism is released, the controller of the sanitation new energy vehicle can control the rotating rod 31 connected to the second hydraulic drive device to rotate, thereby driving the flip plate 32 at the bottom of the battery pack shell to rotate, so that the battery pack shell will be able to slowly move downward under its own gravity, thereby leaving the inner cavity of the sanitation new energy vehicle and contacting the ground; when the battery pack 1 contacts the ground, the rotating wheel 11 installed at the bottom of the battery pack 1 contacts the ground, and at this time the battery pack placement cavity of the sanitation new energy vehicle will be able to detect that the battery pack 1 leaves the sanitation new energy vehicle, and at this time it can transmit this information to the controller, so that the rotating wheel 11 is remotely controlled by the controller to rotate for a certain period of time, and at this time the battery pack 1 will be able to leave the sanitation new energy vehicle, thereby ensuring that the sanitation new energy vehicle will not have a fire.

[0033] Reference Figure 2 , the embodiment of the present application also provides a battery thermal management monitoring system for sanitation new energy vehicles based on the Internet of Things, including: a controller, a chassis, a first hydraulic drive device, a second hydraulic drive device, a battery pack 1, a flip plate 32 and a clamping assembly; The controller is connected to the vehicle owner terminal and the fire control center through the Internet of Things; The battery pack 1 is equipped with a processor 13, a third hydraulic drive device and a rotating wheel 11, and the processor 13 is wirelessly connected to the controller; The first hydraulic drive device and the second hydraulic drive device are fixed on the chassis, and the first hydraulic drive device and the second hydraulic drive device are connected to the controller; The flip plate 32 is arranged at the bottom of the vehicle body and can form a battery pack placement cavity between the flip plate 32 and the chassis; The clamping assembly and the battery pack 1 are both arranged in the battery pack placement cavity; The clamping assembly can be driven by the first hydraulic drive device to move horizontally to a first state of clamping with the battery pack 1 or a second state of releasing the battery pack 1; The flip plate 32 can be driven by the second hydraulic drive device to rotate up and down to protect the clamped battery pack 1 or to move the released battery pack 1 out of the battery pack placement cavity to the ground; Under the control of the controller, the processor 13 can control the third hydraulic drive device to drive the rotating wheel 11 to rotate, so that the battery pack 1 moves away from the sanitation new energy vehicle.

[0034] When the clamping mechanism releases the battery pack 1, the controller controls the second hydraulic drive device to drive the rotating rod 31 to rotate. When the rotating rod 31 rotates, it will drive the flip plate 32 arranged at the bottom of the battery pack 1 to rotate, so that the battery pack 1 will be able to slowly move downward under its own gravity, thereby leaving the battery pack placement cavity of the sanitation new energy vehicle and contacting the ground; when the battery pack 1 is in contact with the ground, the rotating wheel 11 installed at the bottom of the battery pack shell is in contact with the ground, and the camera 12 carried on the battery pack 1 can be used to capture images to identify whether the battery pack 1 has left the battery pack placement cavity; when the camera 12 captures images to determine that the battery pack 1 has left the battery pack placement cavity, the processor 13 installed on the battery pack 1 transmits this information to the controller; the controller remotely controls the rotating wheel 11 to rotate for a certain period of time, so that the battery pack 1 can leave the sanitation new energy vehicle, thereby ensuring that the sanitation new energy vehicle will not have a fire.

[0035] Reference Figure 4 There are two groups of the clamping components, which are symmetrically arranged on both sides of the battery pack 1. Each group of the clamping components includes: a mounting plate 21 connected to the first hydraulic drive device and a clamping block 22 connected to the mounting plate 21, and the clamping block 22 is used to be inserted into the clamping slot 14 set on the battery pack 1.

[0036] Reference Figure 4 One end of the flip plate 32 is fixedly connected to the rotating rod 31, and the rotating rod 31 is connected to the output end of the second hydraulic driving device. The second hydraulic driving device drives the rotating rod 31 to rotate, thereby driving the flip plate 32 to rotate up and down.

[0037] In an embodiment of the present application, the battery pack 1 includes: a battery pack shell, on which a power supply, a GPS positioning module, a camera 12, the processor 13, the rotating wheel 11 and a third hydraulic drive device for driving the rotating wheel 11 to rotate are installed, and the processor 13 is wirelessly connected to the controller; the processor 13 is connected to the camera 12, and the controller recognizes whether the battery pack 1 is moved from the battery pack placement cavity to the ground based on the image captured by the camera 12.

[0038] Reference Figure 2 After the battery pack 1 in the embodiment of the present application leaves the sanitation new energy vehicle, in order to ensure that the sanitation new energy vehicle continues to drive normally, the controller will start the backup battery on the sanitation new energy vehicle and provide the sanitation new energy vehicle with the energy required for its operation through the backup battery.
