Description

Technical Field

[0001] The utility model mainly relates to the technical field of emergency positioning, and specifically, it is a flexible portable emergency positioning and help device. Background Technique

[0002] There are already many mature positioning products on the current market, such as the positioning services of smart phones and mobile devices, vehicle-mounted solar locators, pet locators, etc. Due to different application scenarios and requirements, these products have their own emphases in terms of material size and power supply source. For example, the design of vehicle-mounted solar locators aims to extend the usage time as much as possible to adapt to long-distance travel. Polycrystalline silicon solar panels can be used, which have a relatively high photoelectric conversion efficiency but are heavy and thick, making it not conducive to portable carrying; while pet locators are designed to be small and light, and usually use button batteries or rechargeable batteries as power supply devices, with limited service life and uncertain energy depletion time. The main defects of the current existing technologies are as follows:

[0003] 1. Traditional miniature locator products usually rely on battery power supply. However, due to the limited volume space, it leads to frequent charging or battery replacement, and the service life is limited.

[0004] 2. Traditional emergency communication and rescue devices are usually designed as wrist-mounted devices or mobile phone-like devices. They have a relatively large volume and a larger battery capacity than miniature locators, but their battery life is limited and can only cope with short-distance travel or short-term outings. At the same time, due to their large volume, they are not convenient to carry.

[0005] 3. Although traditional photovoltaic batteries can use solar energy for charging, due to their single form, large mass, inconvenient portability, rigid structure and other disadvantages, their application in portable flexible wearable devices is limited. At the same time, due to their rigid characteristics, potential safety problems such as scratches are also brought. Content of the Utility Model

[0006] To solve the deficiencies of the current technology, the utility model combines the existing technology and starts from the actual application to provide a flexible portable emergency positioning and help device. This device is compatible with the functions of existing commercial emergency locators, and at the same time meets the requirements of long battery life, as well as the function of obtaining solar energy to convert it into electrical energy on the spot under emergency conditions and completing a call for help to the outside world.

[0007] To achieve the above purpose, the technical solution of the utility model is as follows:

[0008] A flexible portable emergency positioning and help device, comprising: an FPC flexible circuit board and a flexible thin-film solar panel.

[0009] The flexible thin-film solar panel is connected to a power management chip, and the power management chip is connected to a rechargeable energy storage device.

The single-chip microcomputer is connected to a Bluetooth module to send the positioning signal data to the Bluetooth module. The Bluetooth module is used to interact with a mobile phone APP to send the positioning data to the mobile phone. The GSM module interacts with the single-chip microcomputer to send a rescue signal of the location information to the outside world.

[0010] This device takes a single-chip microcomputer as the core, adopts a GPS / Beidou positioning module, uses Bluetooth communication as the conventional information transmission mode, can record travel data in real time through a cloud platform, and is also equipped with a GSM short message emergency communication module. An energy system composed of a flexible thin-film solar panel, a power management chip, and a small rechargeable energy storage device (such as a supercapacitor, a lithium battery, etc.) provides energy for the functional modules.

The Bluetooth module sends the positioning information to the mobile phone to send the positioning data, and the mobile phone or the remote cloud server receives and stores these positioning data. In an emergency state, that is, when the energy carried by the mobile phone, power bank, etc. has been exhausted, the flexible thin-film solar panel is used to charge the small rechargeable energy storage device. When the energy requirement for starting the system is met, the GSM short message emergency communication module is used to send a distress signal of the location information to the outside world. The rescue personnel implement effective rescue measures according to the recorded positioning data and the location information of the distress signal.

[0011] Further, an external antenna is installed on the FPC flexible circuit board, and the external antenna is used to receive the positioning signal from the global positioning system. By means of the external antenna, the receiving ability of the positioning signal is improved.

[0012] Further, the global positioning system is a GPS positioning system or a Beidou positioning system.

[0013] Further, the positioning signal obtained by the positioning module is longitude and latitude data. The single-chip microcomputer analyzes and processes the longitude and latitude data, only retains one format of longitude and latitude data, and then sends the data to the Bluetooth module through the serial port.

[0014] Further, in an emergency state, the GSM module uses a short message to send the longitude and latitude data and a distress short message to the mobile phone number of the emergency communication.

[0015] Further, the flexible thin-film solar panel is mounted on the FPC flexible circuit board, and the flexible thin-film solar panel is connected to the FPC flexible circuit board through conductive silver paste or a wire.

[0016] The structural design of this device enables the overall device to be in a thin-sheet structure, facilitating installation on the surfaces of close-fitting clothing, hats, bags, etc. for use. After purchasing this device, users can quickly install the device according to the designed usage scenarios and requirements.

[0017] Furthermore, a switch 1 and a switch 2 are provided on the FPC flexible circuit board. Switch 1 is used to control the power supply of the FPC flexible circuit board, and switch 2 is used to control the GSM module.

[0018] Furthermore, a plurality of LED lights for displaying the working state of the device are provided on the FPC flexible circuit board.

[0019] Through the display of the switch and the LED lights, it is convenient for users to control and operate this device.

[0020] Furthermore, the mobile phone APP interacts with the cloud platform and stores relevant data in the cloud platform.

[0021] Furthermore, the mobile phone APP is used to scroll and display the longitude and latitude data received by the device per second. At the same time, it can call the map interface for path calculation and graphic drawing to generate the user's movement trajectory map. It is connected to the cloud server through the app to transmit and record map data.

[0022] Through the interaction with the cloud platform, users can use any Internet-connected device to access the relevant data stored in the cloud platform, monitor the user's movement trajectory, and provide reliable data support for subsequent rescue.
