Abstract
Description
Technical Field
[0001] This invention relates to the field of engineering blasting safety technology, and in particular to a blasting site warning and safety interlocking system and method based on a smart terminal. Background Technology
[0002] In blasting operations, safety is the primary consideration. Traditional blasting safety management relies mainly on manual experience and simple communication equipment (such as traditional walkie-talkies). Core safety aspects such as the proper deployment of warning points, the clearing of personnel from within the safe distance, and the presence of key personnel all depend on manual reporting and visual judgment. This approach has inherent flaws, including: 1. Inaccurate spatial location assessment, making precise electronic verification impossible and posing serious safety hazards; 2. Lack of personnel identity verification, making it impossible to effectively verify the presence of key personnel and posing risks of impersonation or dereliction of duty; 3. A disconnect between safety procedures and detonation control, with the detonation operation and the confirmation of the aforementioned safety conditions operating independently, lacking a mandatory technical interlocking mechanism, allowing safety procedures to be circumvented; 4. A lack of visualization and remote emergency command and dispatch tools, preventing the command center from having real-time access to the precise location distribution of personnel and on-site visuals, hindering efficient and accurate remote command in emergency situations.
[0003] In the prior art, CN112212751A discloses a blasting accident prevention system, a blasting accident prevention method, and a storage medium. This blasting accident prevention system includes a positioning system, an accident prevention device, and a warning zone, as well as a decision-making device for sending a permission to detonate. The positioning system includes multiple positioning devices, and the location of the detonation point is determined by one of these devices. The warning zone is defined as an area extending outwards from the detonation point at a predetermined distance. The accident prevention device monitors the positions of the multiple positioning devices and the alarm signals they send. If the accident prevention device detects that a positioning device is within the warning zone or receives an alarm signal from a positioning device, it controls the detonation circuit to disconnect, thus prohibiting detonation. This effectively monitors key processes involved in the blasting process and the users of the positioning devices, reducing the incidence of blasting accidents.
[0004] However, this existing technology still has some shortcomings, such as: 1. It relies on a centralized backend system, and the anti-misoperation device needs to continuously communicate with the positioning system and decision-making device. It cannot operate independently in a network-free environment, resulting in low reliability; 2. It lacks a personnel authentication mechanism: it cannot confirm whether key personnel are present in person, posing a risk of impersonation or dereliction of duty; 3. The interlocking mechanism is weak. The detonation control and safety condition confirmation processes are relatively independent, lacking mandatory dynamic interlocking, and safety procedures may be bypassed; 4. The remote command capability is insufficient, as it cannot visualize the location of on-site personnel and the scene in real time, resulting in low emergency command efficiency.
[0005] Therefore, a new technical solution needs to be researched to address the above problems. Summary of the Invention
[0006] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a blasting site early warning and safety interlocking system and method based on intelligent terminals. This system achieves independent operation without relying on a back-end management system, forming a closed-loop safety interlocking system in a network-free environment. At the same time, when the network permits, the intelligent terminal cluster can seamlessly access the back-end management system to enhance the visual command capability and form a dual guarantee of on-site autonomy and remote support.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: A blasting site early warning and safety interlocking system based on an integrated intelligent terminal includes an intelligent terminal cluster, a detonation controller, and a back-end management system. The intelligent terminal cluster includes multiple intelligent terminals, and each intelligent terminal includes: The main control unit has a computing module; The positioning module is used to collect and report the coordinates of the smart terminal in real time; Digital intercom module, used to realize voice communication in clusters of smart terminals; The biometric module is used to collect facial information and verify identity. The wireless self-organizing network module is used to build an independent local area network among smart terminals; The wireless communication module is used for data interaction with the back-end management system; A short-range wireless communication module is used to establish a near-field connection with the detonation controller; Audio and video acquisition module, used to acquire on-site images and videos; The main control unit is connected to the positioning module, digital intercom module, biometric identification module, wireless self-organizing network module, wireless communication module, short-range wireless communication module, and audio / video acquisition module, respectively. The detonation controller includes a detonation controller body, which is equipped with a short-range wireless communication interface for establishing a near-field connection with a designated smart terminal and receiving authorized control signals. The back-end management system is wirelessly connected to each smart terminal; the back-end management system includes: The map engine module is used to load and display an electronic map of the blasting site; The warning and early warning location analysis engine is used for safety distance warning rules and receives location information from smart terminals to calculate the distance between them and the blasting point for safety comparison; the personnel identity authentication and timeliness management module is used to maintain the on-duty status of key personnel. The dynamic authorization and interlocking control module is used to comprehensively judge safety conditions and generate detonation enable tokens; The visual emergency dispatch module is used to enable remote visual intercom and command.
[0008] As a preferred embodiment, the biometric module supports liveness detection by calling the camera API to acquire images and comparing them with local or remote biometric recognition algorithm libraries.
[0009] As a preferred option, the conditions for the dynamic authorization and interlocking control module to generate the detonation enable token include: all alert point locations continuously meet the standards and the key personnel's identity authentication status is valid.
[0010] As a preferred embodiment, the detonation enable token is an encrypted string generated based on the current timestamp, terminal ID, and random number.
[0011] As a preferred option, a remote command center is also included; The remote command center establishes two-way audio and video communication with the smart terminal through the back-end management system to conduct global monitoring and remote visual intervention of the blasting operation site.
[0012] A method for managing blasting site early warning and safety interlocking based on a smart terminal, implemented through the blasting site early warning and safety interlocking system based on an integrated smart terminal as described above, the method comprising the following steps: Step S201: Localization of project presets and security rules; Step S202: On-site self-organizing network construction and distributed location determination; Step S203: Smart terminal side identity authentication and dynamic on-duty status maintenance; Step S204: Safety status aggregation and interlocking judgment; Step S205: Query-based dynamic authorization and near-field detonation.
[0013] As a preferred embodiment, step S205 includes: The demolition commander issued the order to prepare for detonation; The smart terminal connected in the near field to the detonation controller initiates an authorization query request; The smart terminal connected to the detonator in the near field checks all current safety conditions. If the conditions are met, a detonation enable token is generated. When the network allows, the smart terminal that has established a near field connection with the detonator actively submits an authorization log to the back-end management system to record the authorization for detonation. The electronic safety lock is released after the detonation controller verifies the validity of the detonation enable token.
[0014] As a preferred option, when the network permits, the backend management system participates in the authorization verification. If the backend management system returns an activation token, the smart terminal stops its own verification action.
[0015] As a preferred embodiment, in step S201, a blasting project is created and blasting project parameters are set in the background management system. Setting the blasting project parameters includes at least calibrating the coordinates of the blasting center point, setting the safety warning distance, and the theoretical location of the warning point. The blasting project parameters are then synchronously configured to the intelligent terminal cluster, so that the intelligent terminal cluster has all the data for independent operation. In step S202, a self-organizing network is established between the smart terminals; personnel at each alert point carry smart terminals to the designated area, and each smart terminal autonomously and continuously judges whether its own location meets the security alert requirements based on local computing, and shares the status information within the smart terminal cluster. In step S203, key personnel verify their identity through the biometric module of their smart terminal. The verification is completed locally on the smart terminal, and the successful authentication status serves as a valid credential for the personnel to be on duty, and it is time-sensitive. In step S204, the location security status and personnel authentication status of all smart terminals are collected within the smart terminal cluster. The smart terminal cluster is logically ready only when all statuses meet the preset security conditions. Furthermore, after entering the detonation preparation stage, the smart terminal cluster automatically checks whether the authentication status of all key personnel is still valid. If it has expired, it requires re-verification.
[0016] Compared with existing technologies, this invention has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly constructs an intelligent terminal cluster using multiple intelligent terminals. These intelligent terminals can be assigned to the blasting commander, personnel at various warning points, and other on-site workers. The intelligent terminals are mobile devices with multiple capabilities, including computing power, wireless communication capabilities, and DMR digital intercom capabilities. The intelligent terminals are used to achieve monitoring of the blasting site warning area, personnel identification verification, dynamic interlocking of detonation control, and remote visual command. Each intelligent terminal includes a main control unit and, respectively, a power module, positioning module, digital intercom module, biometric module, wireless self-organizing network module, wireless communication module, short-range wireless communication module, audio / video acquisition module, speaker, display unit, storage unit, and microphone connected to the main control unit. Thus, even in a network-free environment (e.g., mobile internet), it can achieve independent operation and form a closed-loop safety interlocking system without relying on a backend management system. When network access (such as mobile internet) permits, the smart terminal cluster can also be seamlessly connected to the back-end management system. The back-end management system can be used to calculate warning positions, perform biometric authentication, dynamic authorization and interlocking control, etc. Furthermore, by utilizing the visual emergency dispatch module, the remote command center can conduct global monitoring and remote visual intervention on site through the back-end management system. When the back-end management system generates an early warning or the blasting command personnel initiate it, the back-end management system can initiate a video call to any smart terminal to establish two-way audio and video communication, realize visual remote command and decision support for blasting operations, and form a dual guarantee of on-site autonomy and remote support.
[0017] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description
[0018] Figure 1 This is a schematic diagram of the overall architecture of the blasting site warning and safety interlocking system based on an integrated intelligent terminal of the present invention; Figure 2 This is a flowchart of the blasting site warning and safety interlocking management method based on intelligent terminals according to the present invention; Figure 3 This is a flowchart of dynamic authorization and detonation interlock control. Figure 4 This is a schematic diagram of the components of a smart terminal; Figure 5 This is a schematic diagram of the back-end management system functions; Detailed Implementation Please refer to Figures 1 to 5 As shown, it illustrates a specific embodiment of the present invention.
[0019] A blasting site early warning and safety interlocking system based on an integrated intelligent terminal includes an intelligent terminal cluster, a detonation controller, and a back-end management system.
[0020] The intelligent terminal cluster comprises multiple integrated intelligent terminals, which are distributed to the blasting commander, personnel at various warning points (and other on-site workers). These intelligent terminals are mobile devices with computing power, wireless communication capabilities, and DMR digital intercom capabilities, enabling monitoring of the blasting site's warning area, personnel identification, dynamic interlocking of detonation control, and remote visual command. Each intelligent terminal includes a main body, a main control unit mounted on the main body, and power modules, positioning modules, digital intercom modules, biometric modules, wireless self-organizing network modules, wireless communication modules, short-range wireless communication modules, audio / video acquisition modules, speakers, display units, storage units, and microphones connected to the main control unit.
[0021] The main control unit has a computing module that is specifically programmed to perform local security judgment functions.
[0022] The power module supplies power to each power-consuming part of the smart terminal; The positioning module is used to collect and report the precise latitude and longitude coordinates of the smart terminal holder in real time. The location service obtains the location by calling the smart terminal operating system API, and shares it in the smart terminal group network and transmits it to the backend management system through a custom application layer data protocol; The digital intercom module is used to realize trunked voice communication; The biometric module is used to collect facial information of personnel, verify personnel identity, and confirm personnel positions. During the facial recognition process, liveness detection is required to prevent photo and video deception. When verifying personnel identity, the smart terminal calls the camera API to collect images (liveness detection is required before collection) and calls a local or remote biometric recognition algorithm library for comparison. The wireless ad hoc network module is used to build an independent local area network among all smart terminals, enabling data communication in environments without internet access. The module is a hardware device based on wireless ad hoc network technology, supporting autonomous node networking, dynamic routing, and low-power communication. It is suitable for temporary or long-term network construction in scenarios without infrastructure. The module is a hardware unit that implements wireless ad hoc network functionality, integrating radio frequency communication, protocol processing, and network management capabilities. Its core functions include: 1. Autonomous networking: Nodes automatically discover neighbors and form multi-hop networks after power-on, eliminating the need for centralized devices; 2. Dynamic routing: Real-time adjustment of data transmission paths via protocols (such as WaveMesh) to adapt to node movement or failures; 3. Low-power optimization: Support for sleep modes (such as asynchronous / synchronous sleep) to extend the battery life of battery-powered devices. The wireless communication module is used to interact with the background management system. The short-range wireless communication module is used to establish a near-field connection with the detonation controller, and typically uses Bluetooth. The audio and video acquisition module is used to acquire on-site images and videos and support remote visual scheduling. Remote visual scheduling is based on existing streaming media technologies (such as H.264 / WebRTC encoding and transmission) to achieve the acquisition, encoding, transmission, and playback of audio and video data. In practical applications, existing streaming media technologies include, but are not limited to, the following: MMS protocol, RTSP protocol, RTMP protocol, HLS protocol, SRT protocol, and WebRTC. The detonation controller, based on existing blasting initiation devices that comply with industry safety standards, adds a short-range wireless communication interface (such as Bluetooth). This allows for short-range communication with a designated smart terminal via Bluetooth to receive authorized control signals from the smart terminal. Only upon receiving a valid encrypted authorization token does it unlock its internal electronic safety lock, allowing physical detonation. The detonation controller typically includes a control circuit board fixed within a housing, and the control circuit board is equipped with control circuitry for generating the detonation current. The back-end management system, deployed in the cloud or on a server, is the control core of the system and includes: a map engine module, a warning and early warning location analysis engine, a personnel identity authentication and timeliness management module, an early warning decision module, a dynamic authorization and interlocking control module, and a visual emergency dispatch module. The map engine module is configured to load and display an electronic map of the blasting site, and to provide real-time visualization of the blasting point, preset warning area, and the location of each smart terminal. The warning and early warning location analysis engine is configured to receive the location information of all smart terminals in real time, automatically calculate the distance between them and the blasting point, and compare it with the preset safety warning distance; the personnel identity authentication and timeliness management module is configured to receive the biometric information uploaded by the terminal for comparison, and timestamp each successful verification behavior to maintain the on-site check-in status of key personnel within the preset validity period. The early warning decision module is configured to automatically generate early warning messages based on the results of location analysis, personnel authentication, and audio analysis. The dynamic authorization and interlocking control module is the core logic of this management system. It is configured to comprehensively judge all safety conditions (all safety conditions include at least condition 1 and condition 2, where condition 1 refers to the continuous compliance of all warning point locations and condition 2 refers to the valid identity authentication status of key personnel). When all conditions are met, a detonation enable token is generated and dynamically sent to a selected smart terminal on site that has established a short-range wireless communication connection with the detonation controller. The visualization emergency dispatch module is configured to receive real-time audio and video streams uploaded by one or more smart terminals, allowing commanders to actively call any smart terminal on site to establish a two-way audio and video communication channel, enabling remote visual intercom and command.
[0023] The above describes the communication between the intelligent terminal cluster, detonation controller, and back-end management system. The communication between these components adopts a custom application layer protocol based on the standard transmission protocol, defining the data structure for various business instructions.
[0024] Furthermore, the system also includes a remote command center. The computer in the remote command center monitors the site globally and provides remote visual intervention through the background management system (cloud server). When the background management system generates an early warning or the blasting command personnel initiate the action, the remote command center can make a video call to any smart terminal to establish two-way audio and video communication, thereby realizing visualized remote command and decision support for the blasting operation site and forming a dual guarantee of on-site autonomy and remote support.
[0025] Next, a method for managing blasting site early warning and safety interlocking based on a smart terminal is provided, which is implemented through the aforementioned blasting site early warning and safety interlocking system based on an integrated smart terminal. The method includes the following steps: Step S201, Project Preset and Safety Rule Localization: Create a blasting project in the backend management system and set the blasting project parameters. The blasting project parameters should include at least the coordinates of the blasting center point, the setting of the safety warning distance, and the theoretical location of the warning point. Synchronize the blasting project parameters to the intelligent terminal cluster so that the intelligent terminal cluster has all the data for independent operation. Step S202, On-site self-organizing network construction and distributed location judgment: A self-organizing network is established among the smart terminals; personnel at each warning point carry smart terminals to the designated area. Each smart terminal, based on local calculation, autonomously and continuously judges whether its own location meets the safety warning requirements and shares the status information within the smart terminal cluster; when the network (mobile Internet) allows, the background management system will also receive the location information of all smart terminals in real time. If the actual distance between the smart terminal and the blasting operation point does not reach the preset safety warning distance, the location warning will be automatically pushed to the background management system. Step S203, Smart Terminal Side Identity Authentication and Dynamic On-Duty Status Maintenance: Key personnel verify their identity through the biometric module of their smart terminals. The verification is completed locally on the smart terminal. The successful authentication status serves as valid proof of the personnel's on-duty status and has a time limit (e.g., after successful verification, the time of successful authentication is recorded, and the personnel's valid authentication status is maintained within a preset validity period, such as 30 minutes). When the network (mobile internet) permits, the backend management system will also record the time of successful authentication in real time and maintain the personnel's valid authentication status within a preset validity period, such as 30 minutes. Step S204, Security Status Aggregation and Interlock Judgment: The location security status and personnel authentication status of all smart terminals are aggregated within the smart terminal cluster; the smart terminal cluster is logically ready only when all statuses meet the preset security conditions; furthermore, after entering the detonation preparation phase, the smart terminal cluster automatically checks whether the authentication status of all key personnel is still within the "valid" period. If it has expired, re-verification is required; when the network (mobile Internet) permits, the dynamic authorization and interlock control module of the backend management system will also automatically check whether the authentication status of all key personnel is still within the "valid" period. If it has expired, re-verification is required. Step S205, Query-based Dynamic Authorization and Near-Field Detonation: First, the smart terminal held by the blasting commander issues a detonation preparation command. Then, the smart terminal, which has established a near-field connection with the detonation controller, checks all current safety conditions. If these conditions are consistently met, the smart terminal returns a "detonation enable token" signal to the detonation controller. When the network (e.g., mobile internet) allows, the smart terminal proactively sends an authorization query request to the backend management system. The backend management system determines if there are any new negative conditions. If so, it returns a detonation disallowed command. Simultaneously, the backend management system saves the authorized detonation enable token and authorization verification log records. Note: The detonation enable token is a dynamically generated encrypted data packet that may contain: command code, timestamp, smart terminal serial number, digital signature, random number, etc. The detonation controller verifies the validity of the timestamp, the legality of the serial number, and the correctness of the digital signature.
[0026] Thus, in a network-free environment (such as mobile internet), a distributed security network with smart terminals at its core and edge computing capabilities can achieve closed-loop security interlocking by using smart terminals to calculate alert locations locally, perform biometric authentication, maintain communication through wireless self-organizing networks, and adopt a dynamic token authorization mechanism with active querying. This allows the network to operate independently in a network-free environment without relying on a backend management system.
[0027] When the network (such as mobile Internet) permits, the smart terminal cluster can also seamlessly access the back-end management system to obtain the latest verification rules and send authorization verification results and authorization verification log records. At the same time, by further utilizing the visual emergency dispatch module, the remote command center can conduct global monitoring and remote visual intervention on site through the back-end management system.
[0028] The key design focus of this invention is: 1. A smart terminal cluster is constructed using multiple smart terminals. These smart terminals can be assigned to the blasting commander, personnel at various warning points, and other on-site workers. The smart terminals are mobile devices with multiple capabilities, including computing power, wireless communication, and DMR digital intercom. They enable monitoring of the blasting site's warning area, personnel identification, dynamic interlocking of detonation control, and remote visual command. Each smart terminal includes a main control unit and connected to it a power module, positioning module, digital intercom module, biometric module, wireless self-organizing network module, wireless communication module, short-range wireless communication module, audio / video acquisition module, speaker, display unit, storage unit, and microphone. This constructs a decentralized security architecture. With the smart terminal cluster at its core, and through edge computing and self-organizing networks, the system achieves highly reliable and autonomous operation in a network-free environment, completely eliminating dependence on a centralized backend.
[0029] 2. It achieves inherently safe interlocking logic: The innovative "query-response" dynamic token mechanism ensures that the detonation controller must obtain the latest security status of the system before each operation, preventing permissions from being tampered with or reused. Its security is far higher than the traditional "issue-execute" mode.
[0030] 3. Achieved precise intelligent management: Through localized terminal calculations, it achieved automatic and accurate judgment of the warning location; through the binding of biometrics with job positions, it ensured the authenticity of key personnel on duty.
[0031] 4. Near-field detonation control: Utilizing the characteristics of short-range wireless communication, the physical distance for detonation control is limited to a safe range.
[0032] 5. Visualization and remote control of command and decision-making have been achieved: Through the enhancement of the back-end management system, the command center can transform from the traditional "listening to reports" to "viewing the scene", realizing transparent and panoramic management of the blasting site, which greatly improves the efficiency of emergency command and the accuracy of decision-making in complex situations.
[0033] 6. A dual guarantee system combining "on-site autonomy" and "remote support" has been constructed: the system can not only ensure independent and safe operation in the most demanding offline environment, but also obtain powerful remote command capabilities when there is a network, forming a flexible, reliable and highly adaptable integrated solution.
[0034] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
