Description

Technical Field

[0001] The present application relates to an intelligent early warning terminal and an intelligent early warning system. Background Art

[0002] With the rise of the new energy vehicle market and the increase in vehicle import and export (international trade) transactions, there is an increasing demand for ocean transportation of various new energy vehicles. However, due to their special requirements for batteries, new energy vehicles are more likely to suffer from thermal failure than traditional vehicles, such as fuel vehicles.

[0003] Therefore, during international transportation (including but not limited to shipping), some new energy vehicles may suffer thermal failure, that is, spontaneous combustion.

[0004] The current means of monitoring thermal failure during transportation are relatively traditional. For example, traditional smoke alarms, once triggered, mean that the ship has entered a combustion state, creating the risk of fire in the entire ship or warehouse. At this time, the risk of human intervention is high, and the overall loss of the accident is very large. Utility Model Content

[0007] Optionally, the intelligent early warning terminal further includes a temperature sensor for acquiring a temperature signal at the vehicle, and the calculation control unit is further used to process the acquired temperature signal.

[0008] Optionally, the intelligent early warning terminal also includes an indicator light.

[0009] Optionally, the intelligent early warning terminal also includes a speaker.

[0010] The present application also proposes an intelligent early warning system, comprising: a plurality of intelligent early warning terminals, wherein the intelligent early warning terminal is an intelligent early warning terminal according to any of the foregoing items; a monitoring platform; and a communication network for communicating and connecting the plurality of intelligent early warning terminals with the monitoring platform.

[0011] Optionally, the communication network is a PoE communication network and includes one or more PoE switches.

[0012] Optionally, the PoE switch can also provide power for the multiple intelligent early warning terminals.

[0013] Optionally, based on the perception radius of the intelligent early warning terminal and the size of the space for placing multiple vehicles, the multiple intelligent early warning terminals are arranged in the space.

[0019] In order to be able to timely warn of battery thermal failure that occurs when a new energy vehicle is parked (for example, during transportation, in a parking lot, or charging at a charging station), the present application embodiment proposes an intelligent warning terminal and an intelligent warning system including the intelligent warning terminal. For the convenience of explanation, the present application embodiment is an intelligent warning system set in a cargo ship cabin during ocean transportation, but the present solution is not limited to this embodiment.

[0020] In order to explain the warning effect of this application as a whole, first refer to Figure 1 The overall structure of the intelligent early warning system is described below. Figure 1It can be seen that the system includes multiple intelligent early warning terminals 101a-n, a communication network 102 and a monitoring platform 103. The intelligent early warning terminal transmits the received information to the communication network 102 to perform corresponding alarm operations. In this embodiment, the communication network 102 can be a PoE communication network, and includes one or more PoE switches, which communicate with the intelligent early warning terminal 101 and the monitoring platform 103 through PoE, can simultaneously perform Ethernet communication, and perform Ethernet power supply to the intelligent early warning terminal 101, with high safety reliability and high efficiency. It can be understood that the PoE communication network is only a preferred embodiment of the communication network 102, and any device that can be used for communication can be applied to the present application scheme, while adopting other power supply methods. The monitoring platform 103 is a visualization platform, which is set in the management room (such as the captain's room) of the parking place of the new energy vehicle, and stores a parking space management database based on the cargo ship structure. The parking space management database stores vehicle information, vehicle location information, cabin number information, intelligent early warning terminal number information bound to the cabin number information, etc., which is used to coordinate the status of all vehicles and locate them in time when the battery thermal failure occurs in the vehicle. It is understandable that the parking space management database based on the cargo ship structure can also be obtained from a remote server. The deployment of the system is completely independent and does not need to be associated with other systems, such as a fire alarm system, so the deployment of the system is very convenient.

[0021] Next reference Figure 2 The structure of the intelligent early warning terminal is described below. Figure 2 As shown, the intelligent early warning terminal includes a microphone 201, a photosensitive sensor 202, a calculation control unit 203 and a communication unit 204. Among them, the microphone 201 and the photosensitive sensor 202 are respectively used to obtain the sound signal and light signal emitted by the vehicle within the perception radius of the intelligent early warning terminal (10 meters in this embodiment). Then, the acquired sound signal and light signal are transmitted to the calculation control unit 203. In the calculation control unit 203, it is possible to identify whether the acquired sound signal and light signal are early warning signals for thermal failure of the vehicle battery according to the law of the sound alarm emitted by the vehicle and the law of the flashing lights emitted by the vehicle. The intelligent early warning terminal also includes an indicator light and / or a speaker. When it is identified as an early warning signal, the indicator light of the intelligent early warning terminal lights up, the speaker makes a sound, and the early warning information is sent to the monitoring platform through the communication unit 204. The early warning information indicates that the intelligent early warning terminal with a specific number has found a problem vehicle, and notifies the staff to find the problem vehicle in time according to the number of the intelligent early warning terminal and the indicator light and speaker. It is understandable that when no warning signal is identified, the intelligent warning terminal can also send monitoring information to the monitoring platform through the communication unit 204, so that the monitoring personnel can fully and timely grasp the monitoring status of all intelligent warning terminals.

[0022] In addition, in this embodiment, the communication unit 204 uses a PoE splitter module to separate the data signal and power transmission of the PoE switch in the intelligent early warning system to provide communication (Ethernet) and power supply (12V power supply) functions respectively. In addition, the intelligent early warning terminal also has sufficient anti-interference function, for example, copper foil shielding can be used to physically resist acoustic interference, and a filtering unit (such as an analog-to-digital converter, an amplifier, etc.) can be used to filter and remove the interference of ambient sound (such as the sound of waves, the sound of rails), thereby accurately identifying the sound signal emitted by the vehicle; a filter or a filter can also be used to filter and remove the interference of ambient light, thereby accurately identifying the light signal emitted by the vehicle. It can be understood that the intelligent early warning terminal used in the embodiment of the present application is only an example, which can include more types of signal collectors, such as a smoke sensor, which can determine whether the vehicle battery is thermally failed by detecting whether there is a smoke signal at the parking place of the vehicle; an electromagnetic sensor, which can determine whether the vehicle battery is thermally failed by detecting the electromagnetic waves generated by the active alarm of the vehicle; and a temperature sensor, which can determine whether the vehicle battery is thermally failed by detecting the temperature at the parking place of the vehicle. By combining the judgment of the above-mentioned multiple signals, a more comprehensive and accurate full-stage early warning can be provided.

[0023] Next reference Figure 3 , Figure 3 This is a schematic diagram of the layout of the system inside the hull. The hull is divided into multiple layers, and a large number of intelligent early warning terminals are evenly arranged on each layer. These intelligent early warning terminals communicate through PoE switch networking.

[0024] Specifically, for different parking spaces, the present application embodiment proposes a variety of intelligent warning terminal layout solutions, such as Figure 4a -d. Figure 4a In -d, the black dots represent the set intelligent early warning terminals, and each grid represents the corresponding distance. Since its layout topology is similar to a honeycomb, it is also called a honeycomb layout.

[0025] Figure 4a -b is the layout topology diagram of the intelligent early warning terminal for a ship with a specification of 200*38 meters.

[0026] First reference Figure 4a Schematic diagram of the dense arrangement of Figure 4a In the figure, each grid represents a length of 5 meters. The detection range of the intelligent early warning terminal used has a coverage radius of 5 meters, and a total of 273 intelligent early warning terminals are required. This dense arrangement has a higher detection accuracy, but requires more intelligent early warning terminals and has a higher cost.

[0027] Figure 4b is a schematic diagram of the sparse arrangement. Figure 4bIn the figure, each grid represents a length of 5 meters. The detection range of the intelligent early warning terminal used has a coverage radius of 10 meters, and a total of 137 intelligent early warning terminals are required. The detection accuracy of this dense arrangement method is explained, but because the detection range of the intelligent early warning terminal is large, the number required is also small, so the cost is low.

[0028] Figure 4c -d is the layout topology diagram of the intelligent early warning terminal for a ship with a specification of 141*28 meters.

[0029] First reference Figure 4c Schematic diagram of the dense arrangement of Figure 4c In the figure, each grid represents a length of 5 meters. The detection range of the intelligent early warning terminal used has a coverage radius of 5 meters, and a total of 135 intelligent early warning terminals are required. This dense arrangement has a higher detection accuracy, but requires more intelligent early warning terminals and has a higher cost.

[0030] Figure 4d is a schematic diagram of the sparse arrangement. Figure 4d In the figure, each grid represents a length of 5 meters. The detection range of the intelligent early warning terminal used has a coverage radius of 10 meters, and a total of 68 intelligent early warning terminals are required. The detection accuracy of this dense arrangement method is explained, but because the detection range of the intelligent early warning terminal is large, the number required is also small, so the cost is low.

[0031] Figure 4a -d show an evenly spaced arrangement, but it is understandable that the intelligent early warning terminals can also be arranged in an unequally spaced manner according to the needs of the actual vehicle parking position.

[0032] The intelligent early warning system proposed in this application can sound an alarm within 10 seconds of a battery thermal failure in a new energy vehicle and 30 minutes before the battery catches fire, which can effectively avoid larger accidents caused by thermal failure.
