Description

Technical Field

[0001] This invention belongs to the technical field of shared charging equipment, specifically relating to an integrated outdoor alarm mobile power supply and alarm system. Background Technology

[0002] With the increasing prevalence of outdoor activities such as hiking, sightseeing, and mining, safety accidents involving outdoor personnel, including getting lost, injuries, and other incidents, are becoming more frequent, leading to a continuous increase in demand for personnel location tracking, emergency calls, and rapid rescue. Currently, the mainstream devices on the market are mainly divided into two categories: traditional shared power banks and ordinary outdoor positioning devices, both of which have significant shortcomings.

[0003] Traditional shared power banks only offer basic functions like QR code rental and regular phone charging. Their limited functionality lacks integrated safety modules such as emergency calls, satellite positioning, and location tracking, rendering them incapable of providing location information in case of distress and completely lacking outdoor emergency rescue capabilities. Furthermore, existing shared power bank interfaces are only compatible with ordinary digital products and cannot power specialized outdoor clothing such as air-conditioned or heated garments, thus limiting their application scenarios.

[0004] Conventional outdoor positioning devices are mostly sold independently as dedicated equipment, resulting in high purchase and usage costs and hindering large-scale deployment through a sharing model. Furthermore, these devices report positioning data at fixed frequencies, failing to differentiate between normal travel and emergency situations, and their signal transmission strategies are inadequate. In mountainous, dense forest, and canyon environments, satellite signals are easily blocked, frequently leading to issues such as lost positioning points, coordinate drift, and distorted or broken tracks. Existing products lack automated data correction and point completion algorithms, making it impossible to reconstruct complete travel routes and significantly hindering search and rescue operations.

[0005] At the management platform level, existing location monitoring systems have simple permission designs, mostly using a single management account model, which cannot achieve data isolation and hierarchical management between operating brands, local emergency management departments, fire departments, and merchants at the locations. When an emergency occurs, alarm information cannot be pushed to all responsible parties simultaneously, and the government-enterprise joint rescue process is cumbersome and the response is delayed, making it difficult to meet the requirements of rapid search and rescue in outdoor scenarios. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated outdoor alarm mobile power supply and alarm system, which solves the problems of existing shared power banks and outdoor positioning devices, such as limited functionality, distorted positioning data, imperfect management system, and low emergency rescue efficiency.

[0007] On the one hand, to achieve the above objectives, the present invention provides the following technical solution: A power supply casing is included, inside which a printed circuit board is installed. The printed circuit board is equipped with a main control MCU, a multimodal satellite positioning module, and an SOS emergency button. A SIM cellular communication module is also installed on one side of the printed circuit board. The SIM cellular communication module is connected to a three-tiered decentralized SaaS cloud data platform. Every 15 minutes, the main control MCU retrieves location information generated by the multimodal satellite positioning module, combines the device number, latitude and longitude, timestamp, scenic spot location code, and remaining battery power of the built-in lithium battery to form a data packet, and uploads it to the three-tiered decentralized SaaS cloud data platform via the bound SIM card cellular network. The multimodal satellite positioning module outputs NMEA 0183 protocol ASCII messages with communication parameters of: baud rate 4800bps, 8 data bits, 1 stop bit, and no parity. When the user presses the SOS emergency button, the main control MCU receives the trigger signal, immediately prioritizes sending an emergency alarm message, and adjusts the location reporting frequency to once per minute, continuously uploading location data at a high frequency until the emergency is lifted.

[0008] Preferably, a cylindrical DC interface and a Type-C interface are also provided on one side of the power supply casing, and a built-in lithium battery is also provided inside the power supply casing.

[0009] Preferably, the multimodal satellite positioning module supports GPS, BeiDou, and GLONASS multimodal positioning and can identify NMEA0183 protocol Talker IDs: GP, BD, and GL. The SIM cellular communication module includes an independent SIM card slot, compatible with SIM cards from the three major domestic operators and overseas operators. Each device is hardware-bound to a unique SIM information, and the device can only be used after the system is flashed and calibrated when the SIM card is replaced.

[0010] On the other hand, it also includes an alarm system for an integrated outdoor alarm power bank, which is applied to the aforementioned power bank. It includes a three-level decentralized SaaS cloud data platform and a cloud trajectory algorithm module, which is used for...

[0011] Preferably, the three-tiered decentralized SaaS cloud data platform includes a brand terminal, an agent terminal, and a merchant terminal. The brand terminal is used for overall control of all devices, hazards, and trajectories, and for configuring device operating parameters. The agent terminal is used to view devices and hazards in its jurisdiction and to conduct on-site rescue based on trajectories. The merchant terminal is used to manage its own location devices and to verify emergency situations on-site. SOS alarm information is pushed synchronously to all three parties for tiered and collaborative handling and rescue.

[0012] Preferably, the specific data processing steps of the cloud trajectory algorithm module are as follows: S0. Obtain the raw coordinate data output by the positioning source, and parse the raw coordinate data into WGS-84 decimal latitude and longitude. NMEA 0183 message verification and data format conversion; The following checksum calculation formula is used: ; In the formula: In an NMEA message, each ASCII character after the start character $ and before the checksum leader *; Data format conversion: Convert NMEA 0183 degree format latitude and longitude to decimal degrees using the following formula: ; ; middle, , Latitude and longitude in decimal system; , For integer degree parts; , For fractions, divide them into parts; take positive values ​​for North latitude and East longitude, and negative values ​​for South latitude and West longitude. S1. The device uploads data packets to the cloud trajectory algorithm module. The data includes five fields: device ID, decimal longitude, etc. Decimal latitude UTC timestamp Scenic spot code S, remaining battery power Valid location identifier Positioning quality level Number of available satellites Ground travel speed Ground heading angle The parsing results are validated and distortion suppressed to obtain a normalized WGS-84 coordinate sequence. S2. Construct a geographic grid partition index, group the WGS-84 coordinate sequence by partition key, and maintain an offset correction cache at the partition granularity. S3. For the coordinates within each group, selectively perform WGS-84 to GCJ-02 nonlinear offset calculation and GCJ-02 to BD-09 quadratic offset calculation based on the offset correction cache, and output the BD-09 coordinates. S4. Synchronously write the BD-09 coordinates into the map rendering pipeline or persistent storage subsystem; S5, GIS layered rendering trajectory; S6. Data archiving and storage.

[0013] Preferably, the GIS layered rendering trajectory is as follows: regular travel trajectory: 15-minute point connection line, ordinary solid line layer; SOS distress pre-arrival trajectory: yellow line; SOS real-time trajectory: red dynamically refreshed line; distress start point highlighted.

[0014] Preferably, the data archiving and storage includes full trajectory binding device ID, rental start and end time, scenic spot number, original NMEA message classification archiving, and historical trajectory.

[0015] Preferably, the trajectories are divided into two categories: conventional historical trajectories are used for passenger flow statistics and post-incident tracing; SOS rescue trajectories integrate historical locations before the incident and high-frequency locations after the incident to provide emergency and fire departments with search and rescue routes.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) This solution retains the traditional rental and charging functions, and adds SOS one-click emergency call, Beidou / GPS multi-mode positioning and trajectory recording functions. It also adds a dedicated DC interface and Type-C interface to adapt to the power supply of air-conditioned clothing and heating clothing respectively, so as to realize the multi-purpose use of one machine and extend to the power supply scenario of outdoor special clothing.

[0017] (2) This solution is designed with a two-level differentiated reporting mechanism: during normal use, the location data is reported once every 15 minutes. After the SOS emergency state is triggered, it automatically switches to high-frequency reporting every minute, taking into account both the needs of low power consumption during daily operation and real-time location tracking in case of danger.

[0018] (3) This solution is equipped with a cloud-based trajectory algorithm module, which can complete message verification, coordinate format conversion, point distortion suppression, and coordinate offset conversion, solve the problems of positioning drift and trajectory breakage in complex outdoor environments, restore the complete travel route, and ensure accurate and reliable positioning data.

[0021] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-3 This invention provides a technical solution: an integrated outdoor alarm mobile power supply. The device is protected by an integrated rigid power supply shell 1, making it suitable for complex outdoor environments such as sun exposure, rain, and minor impacts. The internal components of the power supply shell 1 are assembled in a partitioned layout. The entire printed circuit board 7 serves as the core control carrier, integrating a main control MCU, a multi-modal satellite positioning module 8, and a physical SOS emergency button 2. The side of the board has reserved mounting positions for an independent SIM cellular communication module 6. The device features a high-capacity built-in lithium battery 9 as its core power source. The power supply casing 1 integrates two types of output interfaces: a cylindrical DC interface 4 and a Type-C interface 3, catering to the power needs of outdoor air conditioning clothing and conventional digital devices, respectively. It also comes with an integrated external output cable 5 to charge mobile phones, tablets, and other devices. The SIM cellular communication module 6 has an independent standard card slot, fully compatible with cards from the three major domestic operators and mainstream overseas telecommunications operators. To ensure device data security and management order, the device hardware is bound to the corresponding SIM card information. If the communication card needs to be replaced later, the parameters must be recalibrated through a system flash before normal network connectivity can be restored. Under normal rental and usage conditions, the main control MCU actively wakes up the multi-modal satellite positioning module 8 every 15 minutes according to preset logic to collect location data. It then integrates information such as the terminal's original NMEA 0183 message, the device's unique serial number, real-time latitude and longitude, UTC timestamp, the corresponding scenic area location code, and remaining battery power into a standard communication data packet. Relying on the bound SIM card's cellular network, this data is stably uploaded to the remote three-tiered decentralized SaaS cloud data platform. When a user encounters situations such as getting lost, being injured, or facing sudden danger outdoors, pressing and holding the SOS emergency button 2 on the device will trigger the emergency mechanism. The main control MCU will prioritize pushing alarm messages with an emergency indicator and simultaneously increase the location data upload frequency to once per minute, continuously transmitting location information until the emergency status is manually deactivated.

[0024] The multimodal satellite positioning module 8 supports GPS, BeiDou, and GLONASS multimodal positioning and can identify NMEA 0183 protocol Talker IDs: GP, BD, and GL. Please see Figure 4 The integrated outdoor alarm power bank alarm system includes a three-level hierarchical SaaS cloud data platform and a cloud trajectory algorithm module. The cloud trajectory algorithm module is used to receive terminal positioning data, complete message verification, coordinate transformation, point correction, trajectory completion and smoothing, generate hierarchical visual trajectory and archive it, providing complete route data for platform viewing and emergency search and rescue, and realizing terminal device data reception, analysis, visualization display and hierarchical management.

[0025] Please see Figure 6 The three-tiered decentralized SaaS cloud data platform includes a brand end, an agent end, and a merchant end. The brand end is used for overall control of all devices, hazards, and trajectories, and for configuring device operating parameters. The agent end is used to view devices and hazards in the area under its jurisdiction and to carry out on-site rescue based on the trajectories. The merchant end is used to manage its own site devices and verify emergency situations on-site. SOS alarm information is pushed to all three parties simultaneously, and hierarchical collaborative handling and rescue are carried out.

[0026] Please see Figure 5The specific data processing steps of the cloud-based trajectory algorithm module are as follows: Step 0: NMEA 0183 Message Verification and Data Format Conversion; This step completes message validity verification, coordinate format conversion, and speed unit conversion, filtering out erroneous data at the source and unifying the algorithm's calculation units; The following checksum calculation formula is used: ; In the formula: In an NMEA message, each ASCII character after the start character $ and before the checksum leader *; Data format conversion: Converting NMEA 0183 degree format latitude and longitude to decimal degrees is done using the following formula: ; ; middle, , Latitude and longitude in decimal system; , For integer degree parts; , For fractions, divide them into parts; take positive values ​​for North latitude and East longitude, and negative values ​​for South latitude and West longitude. Step 1: The device uploads a data packet to the cloud trajectory algorithm module. The data includes five fields: Device ID, Decimal Longitude, etc. Decimal latitude UTC timestamp Scenic spot code S, remaining battery power Valid location identifier Positioning quality level Number of available satellites Ground travel speed Ground heading angle The parsed results are validated and distortion suppressed to obtain a normalized WGS-84 coordinate sequence: Single data entry: ; Normal rental without SOS: Reporting cycle =900s (15min), the main control MCU collects location data every 15 minutes and uploads it to the cloud via the bound SIM card. The reporting interval remains constant regardless of whether the device is stationary or moving. SOS Emergency: Upon button press, the device prioritizes sending an emergency alarm message, triggering multi-level pop-up alerts in the background; reporting cycle switching... =60s (1min), upload a set of location data every minute, and continue to report at high frequency until the SOS status is lifted; Using the 3σ anomaly removal model, distortion / drift suppression is applied to the continuous WGS-84 coordinate sequence, and a normalized coordinate sequence is output. Step 2: Construct a geographic grid partition index, group the WGS-84 coordinate sequence by partition key, and maintain an offset correction cache at the partition granularity; Specifically, an equidistant latitude and longitude grid is used to divide the global geographic plane into regular rectangular grids, with each grid being a partition. Offset correction caches are maintained on a partition-by-partition basis to reduce redundant calculations. Step 3: For the coordinates within each group, selectively perform WGS-84 to GCJ-02 nonlinear offset calculation and GCJ-02 to BD-09 quadratic offset calculation based on the offset correction cache, and output the BD-09 coordinates; Step 4: Synchronously write the BD-09 coordinates into the map rendering pipeline or persistent storage subsystem; Step 5: GIS layered rendering of the trajectory; Layering rules: Standard travel trajectory: 15-minute point connection, plain solid line layer; SOS distress trajectory before arrival: yellow line; SOS real-time trajectory: red dynamically updated line; distress start point is highlighted. Step 6: Data archiving and storage.

[0027] Basic archiving: Binding device ID, rental start and end time, scenic area code, and complete trajectory data; NMEA message archiving: Stores raw RMC, GGA, and GSV messages, and abnormal messages are separately categorized and retained for fault tracing; Track classification: Regular historical tracks are used for passenger flow statistics and accident tracing; SOS rescue tracks integrate all locations before and after an emergency, providing emergency and fire departments with search and rescue routes.

[0028] In this application, the built-in lithium battery reserves 10% of its capacity to power the modal satellite positioning module 8.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
