[0027] The main English aliases mentioned in the above scheme have the following meanings: MCU stands for Microcontroller Unit, also known as a single-chip microcomputer. MCU is a chip-level computer formed by integrating a central processing unit (CPU), memory (RAM and ROM), counters, timers and multiple input and output interfaces on a single chip; Open-4G communication module 4 is a module that combines 4G communication functions with open CPU technology. The OpenCPU in the attached figure description is the Open-4G communication module 4; OpenCPU is a technology that runs applications directly inside the communication module; Open Bluetooth generally refers to an open, customizable and programmable Bluetooth technology; GPIO stands for General-Purpose Input / Output, which is an interface in a microcontroller, microprocessor or other integrated circuit; UART stands for Universal Asynchronous Receiver / Transmitter, which is an asynchronous communication protocol for sending and receiving data in serial communication. In UART communication, data is transmitted bit by bit in units of bits; PWM stands for Pulse Width Modulation, which is a method of digitally encoding analog signal levels. The output average voltage or current is controlled by changing the duty cycle of the pulse signal, that is, the ratio of the high level duration to the period; in the above scheme, the operations of GPIO, UART and PWM are all existing technologies, which are controlled by existing systems. They are well known in the art and are understood by practitioners in this industry, so they will not be repeated here. The technical solution provided by the present invention is that when the vehicle alarm and rescue warning light is enabled, the installed disposable battery 5 provides power for the entire system; when the device is not needed in daily use, the device is in a latent mode, and the alarm interrupt module 8 can be configured to control how often it wakes up (one week / one month, etc.). After the device is woken up on time, it will detect the current positioning position and the status of the device, including but not limited to the status of each module. After the detection is completed, all information will be reported to the platform, and when the device is aged / abnormally damaged, it can be discovered and maintained in time. If the warning light body is not used, that is, there is no task to be processed at this time, the MCU module 1 will turn off the power of the Open-4G communication module 2 to put the system into a low-power sleep state to save power and wait for the next task to be generated to wake up the Open-4G communication module 2 again to work.

[0028] When encountering a dangerous situation, the device is in alarm mode by pressing button 6. At this time, the device will enter a tracking mode and continuously send positioning data information and the current dangerous situation to the platform. After the MCU module 1 detects that the vehicle is inoperable, it will directly call the police for rescue; and the device will enter an alarm state, that is, several groups of LED lights 9 will flash quickly, and the TTS voice broadcast module 7 will issue a warning notification to give passing vehicles / pedestrians a preview of the dangerous situation, so that they can know in advance that there is a dangerous situation ahead and take emergency measures in advance. At the same time, during use, the user can configure parameters through the mobile phone. After the device Open Bluetooth module 3 receives it, it can configure different parameters for work (such as the color of the light, the flashing frequency, the voice output of the voice broadcast, etc.).

[0029] The specific working conditions of MCU module 1 after distress are as follows: by connecting to the IO port of MCU module 1, the device is awakened and put into real-time working state. After MCU module 1 is started, the power of Open-4G communication module 2 is turned on, and tasks are given to Open-4G communication module 2 through a custom communication protocol. Open-4G communication module 2 starts external monitoring, data collection and data storage, and then passes the collected data to MCU module 1. After receiving the results, MCU module 1 analyzes the results and communicates with Open-4G communication module 2 for the next task. The owner can connect to Open Bluetooth module 3 through the mobile phone, and Open Bluetooth module 3 communicates through UART Interact with the MCU module 1, for example, inform the MCU module 1 of the parameter information that needs to be configured for configuration, and the MCU module 1 will feed back the configuration result to the Open Bluetooth module 3, and the Open Bluetooth module 3 will then pass the result to the mobile phone; in addition, the Open-4G communication module 2 can also control the power of the BDS / GPS module 4. After turning on the power, it communicates with it through UART. The BDS / GPS module 4 will transmit the acquired positioning information to the Open-4G communication module 2 in real time; the Open Bluetooth module 3 is also connected to the TTS voice broadcast module 7 through UART, and the voice to be broadcast is transmitted to the TTS voice broadcast module 7, and then broadcast through the speaker.

[0030] In general, the MCU module 1 controls the operation of each module, the BDS / GPS module 4 obtains the positioning information, which is processed by the Open-4G communication module 2 and the MCU module 1, and then transmitted to the owner's mobile phone through the Open Bluetooth module 3. At the same time, the TTS voice broadcast module 7 gives relevant voice prompts, and the LED light 9 works at a specific flashing frequency and brightness to attract the attention of others. In daily state, if there is no operation or event triggering, the warning light is in low power sleep to extend the battery life.

[0031] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
