Description

Technical Field

[0001] This invention relates to the field of chemical personnel positioning technology, and in particular to a chemical personnel positioning system based on safe production. Background Technology

[0002] Chemical production is inherently dangerous. In the event of a leak, fire, or explosion, quickly and accurately ascertaining the real-time location and safety status of every person in the plant area is a crucial prerequisite for developing effective emergency evacuation and rescue plans and minimizing casualties.

[0003] To improve personnel safety management, the chemical industry has widely adopted positioning systems based on personnel positioning cards or smart terminals. These systems mainly rely on the Global Positioning System (GPS), BeiDou Navigation Satellite System (BDS), or the wireless positioning network within the plant to track the location of individuals wearing the devices. Under normal circumstances, such systems can effectively serve daily attendance, inspection management, and area access control.

[0004] In emergency situations involving sudden accidents, existing technology for positioning information is often disconnected from the actual status of personnel. When personnel are fleeing in panic, their personal positioning devices are easily lost, damaged, or shut down due to strong impacts. At this time, the device location displayed by the monitoring center can no longer accurately reflect the actual location and safety status of the personnel. Rescue commanders making decisions based on this erroneous positioning information in dangerous areas can easily lead to misjudgment and misallocation of rescue forces, or futilely heading to abandoned equipment locations, wasting precious rescue time and causing irreparable consequences. Therefore, existing technology cannot provide reliable information for assessing personnel status in extreme emergency scenarios and cannot meet the urgent need for precise, dynamic, and interference-resistant management of personnel, the most core element in chemical safety production.

[0005] Therefore, we propose a positioning system for chemical personnel based on safe production. Summary of the Invention

[0006] The main objective of this invention is to provide a chemical personnel positioning system based on safe production.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A chemical personnel positioning system based on safe production includes a remote terminal, an information storage module, several personal positioning modules, and several information input units. The information input units are respectively built into the information modules of the personal positioning modules. Personnel information is stored in the information storage module after being processed by the information input unit. The remote terminal grants the information input unit the permission to supplement information. The remote terminal collects location information from several of the personal positioning modules multiple times and analyzes the matching personnel information entered by the information input unit to obtain the location of the matching personnel. The lost personnel can re-enter their information through the fixed personal positioning module set in a designated safe location in the factory area, or through the information entry unit built into the personal positioning module carried by other personnel. The remote terminal collects the location information of the personal positioning module, the matching personnel and supplementary personnel information entered by the information input unit, and obtains the location of the matching personnel; The remote terminal compares the information of the personnel to be supplemented with the information stored in the information storage module; The remote terminal obtains the location of the personnel being added to the register; The remote terminal removes the location information of the personnel information that was originally matched by the personal positioning module.

[0008] A further improvement of the present invention is that the personal positioning module includes a satellite positioning unit, a fingerprint acquisition unit, a touch screen, a processor, a data transmission unit, and a power supply unit; The power supply unit provides power to the satellite positioning unit, the fingerprint acquisition unit, the touch screen, the processor, the data transmission unit, and the information input unit. Personnel input their identity information through the touch screen and verify their identity information through the fingerprint collection unit; The processor writes personnel information into the information input unit; The data transmission unit transmits the location information of the satellite positioning unit and the personnel information supplemented by the information entry unit to the remote terminal.

[0009] A further improvement of the present invention is that the satellite positioning unit includes at least one satellite positioning chip.

[0010] A further improvement of the present invention is that at least one of the personal positioning modules is installed at the factory gate or in the emergency shelter area.

[0011] A further improvement of the present invention is that the remote terminal also includes an early warning unit. When the remote terminal analyzes and finds that the location of any supplementary personnel information does not match the original location information, the early warning module sends an early warning signal to the personal positioning module carried by the security personnel.

[0012] A further improvement of the present invention is that a housing is installed on the outside of the personal positioning module.

[0013] A further improvement of the present invention is that a connecting strap or support frame is fixedly connected to the side wall of the outer shell.

[0014] A further improvement of the present invention is that it includes the following steps: S1: Configure and match a personal positioning module for each person, and store the initial information in the information storage module; S2: The remote terminal collects the positioning information of each module and the matching personnel information at multiple frequencies to achieve normal positioning; S3: When a person loses their own module, they go to the nearest personal positioning module; S4: The missing person can undergo fingerprint verification and identity information supplementation through the information entry unit of the fixed module; S5: The remote terminal receives the supplementary information and location, compares it with the stored information, confirms the new location of the personnel, and removes the old location from the original module. S6: The remote terminal performs security monitoring and emergency dispatch based on the updated location map of all personnel.

[0015] Compared with existing technologies, by updating and removing the location information of personnel who have left the danger zone but whose personal positioning modules are left behind in the danger zone, it is possible to accurately know the actual personnel information in the danger zone. This makes it easier for rescuers to formulate more accurate rescue plans and avoids the ineffective deployment of rescue personnel due to incorrect information. In this way, it can avoid the additional dangerous workload of rescuers caused by incorrect information. Attached Figure Description

[0021] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. In order to better illustrate the specific embodiments of the present invention, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1 Please see Figure 1-5 A chemical personnel positioning system based on safe production includes a remote terminal 1, an information storage module 2, several personal positioning modules 3, and an information input unit 4 built into each personal positioning module 3.

[0023] In one embodiment, remote terminal 1 is deployed in the factory's central control room or security center. It can be a computing cluster consisting of one or more high-performance servers and monitoring displays. Its core task is to aggregate, analyze, display, and issue commands.

[0024] The information storage module 2 can be integrated into the server of the remote terminal 1, or it can be a separate database server, used to store the identity information, fingerprint templates and unique device codes of the personal positioning module 3 bound to all authorized personnel.

[0025] The personal positioning module 3 is the end-point sensing and execution unit of the system. It is divided into two types: personal and fixed. The personal type is worn by every person entering the production area, while the fixed type is installed in key hub locations, such as factory entrances and emergency shelters.

[0026] In one embodiment, the personal positioning module 3 includes a satellite positioning unit 31, a fingerprint acquisition unit 32, a touch screen display 33, a processor 34, a data transmission unit 35, and a power supply unit 36.

[0027] The satellite positioning unit 31 uses a multi-mode satellite positioning chip, such as a chipset that supports China's BeiDou BDS and the United States' GPS, to improve the availability and accuracy of positioning in complex environments.

[0028] The fingerprint acquisition unit 32 uses optical or capacitive fingerprint recognition technology to collect and verify the biometric characteristics of operators.

[0029] The touch display screen 33 uses a small LCD touch screen to display the operation menu and allow personnel to input their employee ID and other identification information.

[0030] Processor 34, as the core controller of the module, is responsible for coordinating the work of each unit and running positioning data encapsulation, fingerprint comparison algorithms, communication protocols, etc.

[0031] The data transmission unit 35 adopts long-distance radio communication technology as the main communication method and can integrate a 4G / 5G cellular mobile communication module as a backup.

[0032] The power supply unit 36 ​​uses a rechargeable lithium polymer battery.

[0033] The information input unit 4 is not an independent component in terms of hardware, but a functional unit jointly implemented by the fingerprint acquisition unit 32, the touch screen 33 and the processor 34 with specific software logic.

[0034] In a real-time example, the early warning unit 11 is a software program within the remote terminal 1. It has preset analysis rules. For example, when the platform analysis finds that a person logs in on a new device through the supplementary recording mechanism, but the location information of the original bound device is still being reported and is located in a different area, it is determined to be an "one person, multiple devices" anomaly. The early warning unit 11 immediately sends an early warning signal containing personnel information, information that the location information has been changed, and the locations of the two places to the preset safety management personnel's personal positioning module 3 or mobile phone. The safety management personnel can then further verify the information to ensure that the old location information in the dangerous area is incorrect.

[0035] The outer shell 5 serves as a physical protective structure. The outer shell 5 is worn on the wrist or neck via a connecting strap, or fixedly installed on the wall or ground via a support frame at the factory entrance or in a safe area.

[0036] In one embodiment, the working method of this system specifically includes the following steps: S1: Initial matching. Before a person joins the company or enters the factory area, a personal positioning module 3 is assigned to them. The administrator binds the person's identity information with the module's unique code on the remote terminal 1 platform. At the same time, the person's fingerprint information is entered into the system and sent to the designated module. When the person uses the module for the first time, they verify their fingerprint on their own module to complete the activation matching.

[0037] S2: Routine positioning monitoring. When personnel enter the production area wearing the module, the module's satellite positioning unit 31 continuously acquires the location. The processor 34 periodically sends data packets containing location and time to the remote terminal 1 through the data transmission unit 35. After receiving the data, the platform matches the corresponding personnel according to the unique code and updates and displays their location on the electronic map in real time.

[0038] S3: Trigger emergency data recording. If a person loses or damages their personal positioning module during an escape due to an accident, the system will lose its accurate positioning. In this case, the lost person can go to the nearest fixed personal positioning module, such as in an emergency shelter, or use the personal positioning module 2 of another person who has been safely rescued to record information. During the trial, a reward and punishment mechanism can be used to encourage people to record information in a timely manner after being safe, providing convenience for rescuers.

[0039] S4: Perform identity supplementation. When the lost person arrives at the fixed module, or through the operation of the personal positioning module 2 carried by other personnel who are already safe, the information supplementation function is selected through the touch screen 33. The identity information is entered in sequence and verified on the fingerprint collection unit 32. The processor 34 packages the supplementation information of this operation, the positioning information of the personal positioning module 2, the unique code information, and the fingerprint feature code of successful verification.

[0040] S5: Remote comparison and update. The personal positioning module 2 sends the supplementary information packet and its own location information to the remote terminal 1 through the data transmission unit 35. After receiving the data, the platform executes the core logic: 1. Information comparison: Using the received employee ID and fingerprint feature code, quickly retrieve the information in information storage module 2 to confirm the operator's identity.

[0041] 2. Location Update: Immediately update the icon of the confirmed person to the location of the fixed module that sent this supplementary information.

[0042] 3. Removal of old location: At the same time, the platform automatically removes or marks the location information of the lost module that was originally bound to the person, so as to avoid confusion of "one person, two locations" on the monitoring map.

[0043] S6: Emergency Monitoring and Dispatch. After completing the above updates, the emergency command center will be able to clearly and accurately see all personnel who have safely arrived at the shelter and those still moving on the platform map. The platform can generate statistical reports and dispatch rescue forces based on this precise information.

[0044] In one embodiment, when no danger occurs, the remote terminal 1 only grants information supplementation permissions to the information input unit built into the personal positioning module that is fixedly installed at the factory entrance or in the refuge area, so as to avoid personnel arbitrarily supplementing information and causing chaos in the recording of positioning information during the safe period.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
