[Technical Field]

[0001] The present invention relates to an abnormality warning system, and more particularly to a vehicle temperature abnormality warning system. [Background technology]

[0002] Motor vehicles are a common means of transportation for users, and whether they are cars or motorcycles, users park their motor vehicles in parking spaces and then leave them. However, because the parking space where a user parks a motor vehicle may be outdoors, or even if the parking space is inside the user's home, if an abnormality occurs in the motor vehicle, particularly a combustion due to an abnormal temperature, the user may not be able to immediately detect it. Summary of the Invention [Problem to be solved by the invention]

[0003] This has led to the current need to research how to provide a vehicle temperature abnormality warning system. [Means for solving the problem]

[0005] As described above, the vehicle temperature abnormality warning system of the present invention uses a non-contact temperature sensor to detect the temperature of the chassis of an electric vehicle, and if the temperature is too high, it activates an early warning function to notify the monitoring center or the vehicle owner, and also activates the cooling equipment to prevent the vehicle from catching fire or burning.

[0007] Referring to FIG. 1, FIG. 1 is a block diagram illustrating a first embodiment of a vehicle temperature alarm system according to the present invention. The vehicle temperature alarm system 1 is installed in a parking space and includes a housing 11, a first temperature sensing module 12, a signal processing module 13, and a signal transmission module 14. The first temperature sensing module 12 is located within the housing 11 and senses the temperature of the vehicle chassis to generate a first temperature signal. The signal processing module 13 and the signal transmission module 14 are both located within the housing 11. The signal processing module 13 is connected to the first temperature sensing module 12 to receive the first temperature signal and determine whether the first temperature value of the first temperature signal exceeds a predetermined value. The signal transmission module 14 is connected to the signal processing module 13 and transmits an alarm signal. When the first temperature value exceeds the predetermined value, the signal processing module 13 generates a trigger signal and sends it to the signal transmission module 14, causing the signal transmission module 14 to transmit the alarm signal.

[0008] In one embodiment of the present invention, the housing 11 is made of a metal material. In another embodiment of the present invention, the housing is made of a waterproof material. Alternatively, in one embodiment of the present invention, the housing may be made of both a metal material and a waterproof material. In one embodiment of the present invention, the housing includes a base and a top cover, and the base and the top cover form storage spaces for installing the modules. The base and the top cover are fastened together to the parking space by fasteners, such as screws or adhesive. In addition, the surface of the top cover includes a circular chamfer to prevent excessive vibration when the device is run over by a vehicle.

[0009] Referring to FIG. 2, FIG. 2 is a block diagram illustrating a second embodiment of a vehicle temperature warning system according to the present invention. In this embodiment, the vehicle temperature warning system 1 further includes a second temperature sensing module 15, which is mounted on the housing 11 opposite the first temperature sensing module 12 and connected to the signal processing module 13. The second temperature sensing module 15 senses the temperature of the vehicle chassis, generates a second temperature signal, and transmits the second temperature signal to the signal processing module 13. The signal processing module 13 determines whether the second temperature value of the second temperature signal exceeds a predetermined value. If the second temperature value exceeds the predetermined value, the signal processing module 13 generates a trigger signal and transmits it to the signal transmission module 14. In this embodiment, the vehicle temperature warning system 1 further includes the second temperature sensing module 15 because the vehicle is long from front to back but short from side to side. Therefore, to minimize temperature detection errors due to variations in the installation position of the first temperature sensing module 12, the second temperature sensing module 15 is further provided to sense the temperature of the vehicle chassis. The first temperature sensing module 12 and the second temperature sensing module 15 are installed longitudinally along the vehicle. Preferably, the first temperature sensing module 12 and the second temperature sensing module 15 are spaced apart by 1 m or more.

[0010] 2, the vehicle temperature warning system 1 further includes a distance sensing module 16 mounted in the housing 11 and connected to the signal processing module 13, which generates a distance sensing signal and transmits it to the signal processing module 13. The signal processing module 13 adjusts the predetermined value according to the distance value of the distance sensing signal. As described above, variations in the installation positions of the temperature sensing modules 12 and 15 can result in large temperature sensing errors. Therefore, in this embodiment, the vehicle temperature warning system 1 further adjusts the predetermined value based on the distance value generated by the distance sensing module 16. For example, if the distance sensing module 16 detects that the chassis height of vehicle A is high, the first and second temperature sensing modules 12 and 15 will be insensitive to temperature sensing. Therefore, the signal processing module 13 is adjusted accordingly to set a smaller predetermined value so as to increase the temperature sensitivity of the first and second temperature sensing modules 12 and 15. If the distance sensing module 16 senses that the chassis height of vehicle B is low, the temperature sensing of the first temperature sensing module 12 and the second temperature sensing module 15 will be sensitive, so the signal processing module 13 will adjust accordingly and set a large predetermined value to reduce the temperature sensitivity of the first temperature sensing module 12 or the second temperature sensing module 15. In this embodiment of the present invention, the distance sensing module 16 is an infrared sensor or a microwave radar.

[0011] In the embodiment of FIG. 2, the vehicle temperature alarm system 1 further includes an environmental temperature sensing module 17, which is connected to the signal processing module 13 and mounted on the housing 11, for generating an environmental temperature sensing signal and transmitting it to the signal processing module 13. The signal processing module 13 adjusts the predetermined value according to the magnitude of the environmental temperature value of the environmental temperature sensing signal. Because variations in temperature detection can occur depending on the environmental temperature around the parking space where the vehicle is parked, in this embodiment, the vehicle temperature alarm system 1 further adjusts the predetermined value based on the magnitude of the environmental temperature value generated by the environmental temperature sensing module 17. For example, if the environmental temperature sensing module 17 detects that the environmental temperature around the parking space where Car A is parked is low, such as when Car A is parked in an indoor parking lot in winter, the first and second temperature sensing modules 12 and 15 will be insensitive to temperature detection. Therefore, the signal processing module 13 adjusts accordingly to set a smaller predetermined value to increase the temperature sensitivity of the first and second temperature sensing modules 12 and 15. When the ambient temperature sensing module 17 senses that the ambient temperature at the parking position of car B is high, for example when car B is parked in an outdoor parking lot in summer, the first temperature sensing module 12 and the second temperature sensing module 15 will be sensitive to temperature, so the signal processing module 13 will adjust accordingly and set a large predetermined value to reduce the temperature sensitivity of the first temperature sensing module 12 or the second temperature sensing module 15. In this embodiment of the present invention, the ambient temperature sensing module 17 is a temperature sensor.

[0012] 2, the vehicle temperature abnormality warning system 1 further includes a storage module 18 connected to the signal processing module 13 and configured to store the first temperature signal or the second temperature signal. In the embodiment of the present invention, the storage module 18 is a memory card such as an SD card.

[0013] The signal transmission module 14 may be any of various wired or wireless transmission modules, including a Bluetooth transmission module, a WIFI transmission module, a 4G / 5G signal transmission module, and a network transmission path. The first temperature sensing module 12, the second temperature sensing module 15, and the environmental temperature sensing module 17 are connected to the signal processing module 13 via an I2C (Inter-Integrated Circuit) to transmit temperature sensing signals to the signal processing module 13. The distance sensing module 16 is connected to the signal processing module 13 via a Universal Asynchronous Receiver / Transmitter (UART) to transmit distance sensing signals to the signal processing module 13.

[0014] In the embodiment of FIG. 2, the vehicle temperature alarm system 1 further includes an operation module 19, which can be installed on any wall (not shown) around the parking space or directly on the housing 11 of the vehicle temperature alarm system 1. When the operation module 19 is installed on the wall, it is connected to the signal transmission module 14 and is connected to the wireless transmission module via wireless transmission technology, so that operation signals can be transmitted. When the operation module 19 is installed in the housing 11 of the vehicle temperature alarm system 1, it is connected to the signal processing module 13 via the signal transmission module 14 by wire, so that operation signals can be transmitted. The operation module 19 provides an input interface, through which the user can set default values ​​and destinations for the alarm signal.

[0015] In an embodiment of the present invention, the destinations of the alarm signal include the vehicle owner's mobile phone, a monitoring center, a building manager, police and fire departments, and cooling equipment around the parking space, such as a sprinkler system; the transmission methods include telephone, message, and email; and the modes of the alarm signal include a flashing light and an alarm sound.

[0016] 3, which is a step flowchart of the vehicle temperature abnormality warning method of the present invention. The vehicle temperature abnormality warning method includes the following steps: In step S11, the first temperature sensing module senses the temperature of the vehicle chassis and generates a first temperature signal. In step S12, the signal processing module receives the first temperature signal and determines whether the first temperature value of the first temperature signal exceeds a predetermined value. In step S13, if the first temperature value exceeds the predetermined value, the signal processing module generates a trigger signal and sends it to the signal transmission module, causing the signal transmission module to transmit an alarm signal. If the first temperature value does not exceed the predetermined value, the process returns to step S11, and the first temperature sensing module continues to sense the temperature of the vehicle chassis and generate the first temperature signal.

The vehicle temperature warning system 1 is installed in an appropriate position depending on the size of the parking stall P, or in the parking stall P depending on the location of the rechargeable battery in the electric vehicle. As described above, the upper cover surface of the housing 11 of the vehicle temperature warning system 1 includes an arc-chamfered edge to prevent excessive vibrations when run over by a vehicle C. Furthermore, the first temperature sensing module 12, the second temperature sensing module 15, the distance sensing module 16, the ambient temperature sensing module 17, and the memory module 18 of the vehicle temperature warning system 1 are provided in the housing 11, and the signal processing module 13 and the signal transmission module 14 are provided in the accommodation space 111 included in the housing 11.
