Description

Technical Field

[0001] The present invention relates to the technical field of fireworks and firecrackers, and in particular to a fireworks and firecrackers setting-off control system and method based on geographic fencing and optical communication. Background Art

[0002] Fireworks and firecrackers can explode and produce a certain amount of open flames during the burning process, so the safe burning of fireworks and firecrackers is an important issue involving public safety, environmental protection and traditional cultural protection. In recent years, with the acceleration of urbanization and the increase in environmental awareness, China has gradually strengthened the regulation of the burning of fireworks and firecrackers.

[0003] Although the setting off of fireworks and firecrackers is somewhat dangerous, some people believe that setting off fireworks and firecrackers is an important part of the Spring Festival culture. Therefore, there is a certain flexibility in the supervision of the setting off of fireworks and firecrackers. Many cities (especially first- and second-tier cities) have designated prohibited or restricted areas. For example, setting off of fireworks and firecrackers is prohibited in core urban areas, transportation hubs, cultural relics protection sites and other areas throughout the year, but can be set off in non-prohibited areas.

[0004] There are certain difficulties in supervising the discharge of fireworks and firecrackers, mainly including: ① The discharge behavior is scattered and concentrated in time, manual supervision is inefficient, and it is difficult for law enforcement departments to monitor comprehensively; ② The existing management measures lack linkage control with geographic information, and law enforcement efficiency is low when the discharge location is manually defined; ③ There is a lack of a traceable discharge behavior record system. If an accident occurs due to random discharge, it will be difficult to hold people accountable later; ④ Traditional open flame fuses are discharged randomly and are difficult to control.

[0005] Therefore, there is a lack of a fireworks and firecrackers discharge control system based on safe and compliant discharge. Summary of the invention

[0006] The purpose of the present invention is to propose a fireworks and firecrackers control system and method based on geographic fencing and optical communication, which ensures the safe discharge and supervision of fireworks and firecrackers through satellite positioning, optical communication technology and image recognition technology, and is particularly suitable for supervision scenarios in government-designated no-burning areas.

[0009] As a preferred solution, the information image further includes an appearance image. The image acquisition module captures the appearance image of the fireworks terminal and compares it with the appearance image in the product filing database to determine whether the fireworks terminal is refitted.

[0010] As a preferred solution, the electronic fuse module and the signal processing circuit are enclosed inside the fireworks terminal.

[0011] As a preferred solution, the image acquisition module is further used to obtain the environmental information image of the fireworks terminal, analyze the scene characteristics of the environmental information image according to the image recognition algorithm. If the fireworks terminal to be set off is in a dangerous setting-off scene, the mobile terminal cannot obtain the permission of the product key library; if the fireworks terminal to be set off is in a safe scene, the mobile terminal can obtain the communication protocol and product key of the product key library.

[0012] As a preferred solution, the electronic fuse module includes a pre-charging circuit, an electrothermal element, and a switching element; The pre-charging circuit is used to boost the voltage for the electrothermal element; The switching element is used to control the on-off of the circuit of the electrothermal element; The electric heating element is used to ignite the firecracker body.

[0013] As a preferred solution, the firecracker terminal optical communication module includes a power indicator and an optical communication transmitting tube and an optical communication receiving photosensitive tube; The power indicator and the optical communication transmitting tube are used to transmit the circuit state before the fireworks and firecrackers terminal is set off to the image acquisition module; The optical communication receiving photosensitive tube is used to receive the ignition signal from the mobile terminal optical communication module.

[0014] As a preferred solution, the fireworks and firecrackers terminal has a voltage feedback module for feeding back the circuit state of the electronic fuse module, and sends the obtained circuit state to the mobile terminal.

[0015] A method for controlling the setting off of fireworks and firecrackers based on a geographical fence and optical communication includes the following steps: Step 1: The person setting off the fireworks uses the built-in program of the mobile terminal to connect to the cloud server based on the network and complete identity authentication; Step 2: Use the satellite positioning module of the mobile terminal to obtain the real-time geographical coordinates of the mobile terminal and the fireworks and firecrackers terminal; With the help of the processor of the mobile terminal, compare the obtained real-time geographical coordinates with the geographical fence database of the cloud server to determine whether the geographical coordinates where the fireworks and firecrackers terminal is located are in a no-set-off area; if the geographical coordinates where the fireworks and firecrackers terminal is located are within the no-set-off area, then remind the person setting off the fireworks through the mobile terminal that they cannot set off or try again; Step 3: If the geographical coordinates where the fireworks and firecrackers terminal is located are outside the no-set-off area, the person setting off the fireworks uses the image acquisition module of the mobile terminal to capture the fireworks and firecrackers terminal to be set off to obtain an information image, and compare the information image with the information image in the product record database of the cloud server to match the product information of the fireworks and firecrackers terminal; Step 4: If the mobile terminal can accurately match the product information of the fireworks and firecrackers terminal, authorize the mobile terminal to retrieve the product key library of the cloud server to obtain the communication protocol for connecting the fireworks and firecrackers terminal and the mobile terminal, and the product key corresponding to the product information of the corresponding fireworks and firecrackers terminal under this communication protocol; Step 5: The person setting off the fireworks makes the mobile terminal optical communication module establish an optical communication connection with the corresponding firecracker terminal optical communication module based on the obtained communication protocol and product key, and can send an ignition signal to the fireworks and firecrackers terminal through the mobile terminal after being ready; Step 6: The signal processing circuit processes the ignition signal received by the firecracker terminal optical communication module and controls the electronic fuse module to start to ignite the firecracker body.

[0016] As a preferred solution, a discharge record database is built in the cloud server. After the firecracker body is ignited, the identity information of the discharger, the model of the fireworks and firecrackers terminal, and the geographical coordinate information of the discharge location are encapsulated and uploaded to the discharge record database.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

The words "one", "an" or "the" and the like used in the patent application specification and claims of the present invention do not express quantity restrictions, but indicate the existence of at least one; the words "first", "second" and "third" used in this document shall not be regarded as restrictions on the order of components, but are only used to distinguish different components; words such as "include" or "comprise" and the like indicate that the elements or objects appearing before "include" or "comprise" include the elements or objects listed after "include" or "comprise" and their equivalents, but do not exclude other elements or objects with the same function.

[0027] In order to more clearly describe the fireworks and firecrackers control system and method based on geographic fence and optical communication, Figures 1-3 Describe this embodiment: like Figures 1-3 As shown, a fireworks and firecrackers control system based on geographic fencing and optical communication includes a mobile terminal A, a fireworks and firecrackers terminal B and a cloud server C; The cloud server C is constructed with a geographic fence database 10, a product filing database 12 and a product key library 11; the geographic fence database 10 stores geographic area data, which is divided into regions and forms an electronic fence according to the government's fireworks and firecrackers management policy, and the geographic area data is updated in real time; the product filing database 12 stores barcode information images and appearance images declared by the manufacturer when filing the fireworks and firecrackers terminal B; the product key library 11 stores communication protocols and product keys, and the product keys correspond one-to-one to the information image data in the product filing database 12; The fireworks and firecracker terminal B includes a firecracker body B1, an electronic fuse module for igniting the firecracker body B1, a firecracker terminal optical communication module for receiving an ignition signal, and a signal processing circuit 4 for processing the ignition signal and controlling the start of the electronic fuse module; The mobile terminal A (including but not limited to smart phones, tablets) at least has a satellite positioning module (GPS / Beidou) for determining the real-time geographical coordinates of the mobile terminal A, an image acquisition module 8 for capturing the information images of the fireworks terminal B to be set off (including bar code information images and appearance images), and a mobile terminal optical communication module 9 for sending an ignition signal to the optical communication module of the firecracker terminal; The mobile terminal A is used to connect to and retrieve the geographical fence database 10 and the product record-filing database 12 of the cloud server C; compare the real-time geographical coordinates with the data in the geographical fence database 10 to determine whether the geographical coordinates where the fireworks terminal B is located are in a no-set-off area; compare the captured information images of the fireworks terminal B with the information images in the product record-filing database 12 to match the product information (product "identity") of the corresponding fireworks terminal B; If the mobile terminal A can accurately match the product information of the fireworks terminal B, and the geographical coordinates where the fireworks terminal B is located are outside the no-set-off area, then the mobile terminal A is authorized to retrieve the product key library 11 to obtain the communication protocol that can connect the fireworks terminal B and the mobile terminal A (this communication protocol is common to this product) and the product key corresponding to the product information of the corresponding fireworks terminal B under this communication protocol (this product key corresponds one-to-one with the product information, and one product key is used to detonate one firework); The mobile terminal A can establish an optical communication connection between the mobile terminal optical communication module 9 and the corresponding optical communication module of the firecracker terminal based on the obtained communication protocol and product key (by establishing a two-way optical communication link (wavelength range 380 - 780nm), and for improving security, dynamic key verification can be performed), so as to send an ignition signal to the fireworks terminal B through the mobile terminal A.

[0028] In the above embodiment, the information images include bar code information images and appearance images. A product information bar code 13 (the bar code includes bar code and two-dimensional code) uniquely corresponding to the product information is provided on the fireworks terminal B. The image acquisition module 8 obtains the bar code information image by capturing the product information bar code 13, and determines the uniquely corresponding product by comparing the bar code information images; the image acquisition module 8 captures the appearance image of the fireworks terminal B and compares it with the appearance image in the product record-filing database 12 to determine whether the fireworks terminal B is refitted. After the product is refitted, since its appearance changes, the corresponding product key cannot be matched.

[0029] In the above embodiment, the optical communication module of the firecracker terminal needs to perform optical communication in the visible light mode, so it is arranged on the outer side of the firecracker body; in order to avoid traditional open flame ignition and improve security, the electronic fuse module and the signal processing circuit 4 are enclosed inside the fireworks terminal B. Such a design can also prevent the electronic fuse module and the signal processing circuit 4 from being privately refitted.

[0030] The optical communication module of the mobile terminal 9 and the optical communication module of the firecracker terminal achieve data transmission through PWM dimming technology; In the above embodiment, the optical communication module of the firecracker terminal includes a power indicator and an optical communication transmitting tube 2 and an optical communication receiving photosensitive tube 3; the power indicator and the optical communication transmitting tube 2 are used to transmit the circuit state before the fireworks and firecrackers terminal B is set off to the image acquisition module 8; the optical communication receiving photosensitive tube 3 is used to receive the ignition signal from the optical communication module 9 of the mobile terminal.

[0031] The optical communication module 9 of the mobile terminal can specifically be a flashlight, and transmits the ignition signal to the optical communication receiving photosensitive tube 3 through the flashing of the flashlight at a specific frequency.

[0032] Using light-emitting diodes and photosensitive tubes as optical communication components on fireworks and firecrackers has a relatively low cost, while on the mobile terminal, using the flashlight and camera carried by the mobile terminal itself as communication devices does not require modification or addition; during the optical communication process, the visible light frequency band (380 - 780 nanometers) is adopted, and pwm modulation is used for transmission during communication (that is, bright and dark changes, and data is represented by adjusting the ratio of the interval time of bright and dark), and visually, the light is flashing and changing during communication, and the working state can be perceived by the naked eye; Since optical communication is naturally vulnerable to interference from external light sources, and this solution is an open system (such as fiber optic communication is a closed system), the distance between the intelligent mobile terminal device and the fireworks and firecrackers cannot be too far apart (about 1 - 5 meters) during specific applications. This ensures that the relative positions of the intelligent device and the fireworks and firecrackers are limited (to prevent remote operation by the igniter), and indirectly ensures the correlation between the positioning of the intelligent mobile terminal and the position of the fireworks and firecrackers (so that the spatial positions of mobile terminal A and fireworks and firecrackers terminal B can be regarded as equivalent); currently, mainstream short-distance wireless communications (4G, Bluetooth, wifi, other RF radio frequency communications) are basically radio frequency wireless communications, which require specific devices or circuits and have a relatively high cost. At the same time, due to the characteristics of radio frequency signals, they can transmit over relatively long distances (even through walls), and if the transmission power is artificially increased, the communication distance can easily exceed several kilometers. And combined with their working mechanisms, the above communication methods are easily controlled maliciously and are not easily detected.

[0033] In the above embodiment, a power supply battery 1 is further provided inside the fireworks and firecrackers terminal B, which is used to provide power for the electronic fuse module, the optical communication module of the firecracker terminal, and the signal processing circuit 4; The electronic fuse module includes a pre-charging circuit 5, an electro-thermal element 6, and a switching element 7; the pre-charging circuit 5 is used to boost the voltage for the electro-thermal element 6 (prepare the corresponding amount of electricity); the switching element 7 is used to control the on-off of the circuit of the electro-thermal element 6; the electro-thermal element 6 is placed in the gunpowder of the firecracker. After the pre-charging circuit 5 boosts the voltage, the electro-thermal element 6 (which can be a resistance wire) generates heat to a sufficient temperature to ignite the gunpowder of the firecracker body B1 or the built-in fuse.

[0034] The image acquisition module 8 can specifically be a camera.

[0035] Furthermore, to improve the safety of setting off and not affect the surrounding buildings; While the image acquisition module 8 acquires the appearance image of the fireworks and firecrackers terminal B, it simultaneously acquires the environmental information image of the fireworks and firecrackers terminal B. According to the image recognition algorithm, it analyzes the scene characteristics of the environmental information image. If the fireworks and firecrackers terminal B to be set off is in a dangerous setting-off scene, the mobile terminal A cannot obtain the permission of the product key library 11; if the fireworks and firecrackers terminal B to be set off is in a safe scene, the mobile terminal A can obtain the communication protocol and product key of the product key library 11. The above-mentioned scene characteristics include but are not limited to vegetation coverage rate, high-risk places (such as gas stations, inflammable and explosive warehouses, etc.), densely populated areas, etc.; the vegetation coverage rate mainly judges the number of shrubs or arbors in the scene, and the densely populated area mainly judges the number of people in the scene. If the number is too large and the distance is relatively close, the person setting off is reminded to change the setting-off position. If not transferred, setting off cannot be carried out. After transferring the setting-off position, the scene characteristics are recognized again until the requirements are met; high-risk places can be identified relying on danger signs.

[0036] In the above embodiment, the fireworks and firecrackers terminal B has a voltage feedback module 15 for feeding back the circuit state of the electronic fuse module, and sends the obtained circuit state to the mobile terminal A. If the voltage is normal, the person setting off is prompted to enter the preparation state.

[0037] The present invention also provides a method for controlling the setting off of fireworks and firecrackers based on a geographical fence and optical communication, including the following steps: Step 1: The person setting off uses the built-in program (or APP) of the mobile terminal A to connect to the cloud server C based on the network 14 and complete the identity authentication; Specifically, during identity authentication, fingerprint recognition can be carried out with the help of the fingerprint recognition module of the mobile terminal A, face and environment recognition can be carried out with the help of the image acquisition module 8, and a permit is issued to a person who meets the identity characteristics (such as a person over 18 years old or the manager of a fireworks performance organized by the government). After passing the permit, setting off can be carried out; Step 2: Use the satellite positioning module of the mobile terminal A to obtain the real-time geographical coordinates of the mobile terminal A and the fireworks and firecrackers terminal B; The processor of the mobile terminal A compares the obtained real-time geographical coordinates with the geographical fence database 10 of the cloud server C to determine whether the geographical coordinates where the fireworks terminal B is located are in the no-fireworks zone; if the geographical coordinates where the fireworks terminal B is located are within the no-fireworks zone, the mobile terminal A is used to remind the igniter not to set off fireworks or to try again; Step 3: If the geographical coordinates where the fireworks terminal B is located are outside the no-fireworks zone, the igniter uses the image acquisition module 8 of the mobile terminal A to capture the information image of the fireworks terminal B to be set off, and compares the information image with the information image in the product record database 12 of the cloud server C to match the product information of the fireworks terminal B; if it cannot be recognized, the igniter is reminded not to set off fireworks or to try again; The information image includes a barcode information image and an appearance image. When capturing the appearance image of the fireworks terminal B to be set off, a dynamic method can be used to perform multi-angle image verification to improve the accuracy of verification; In this step, the environmental information image of the fireworks terminal B is simultaneously obtained, the scene features of the environmental information image are analyzed according to the image recognition algorithm, and it is analyzed whether it is in a dangerous fireworks setting or location. Classification early warnings are carried out according to the geographical coordinates and scene features and the early warning information is transmitted to the igniter, which can be divided into: early warning (distance from the no-fireworks zone < 100m), first-level control (entering the no-fireworks zone), second-level control (environmental risk exceeding the standard); Step 4: If the mobile terminal A can accurately match the product information of the fireworks terminal B, the mobile terminal A is authorized to retrieve the product key library 11 of the cloud server C to obtain the communication protocol for connecting the fireworks terminal B and the mobile terminal A and the product key corresponding to the product information of the fireworks terminal B under this communication protocol; Step 5: The igniter uses the obtained communication protocol and product key to establish an optical communication connection between the optical communication module 9 of the mobile terminal and the corresponding optical communication module of the firecracker terminal (for improved security, dynamic key verification can be performed), and after being ready, the igniter can send an ignition signal to the fireworks terminal B through the mobile terminal A; Step 6: The signal processing circuit 4 processes the ignition signal received by the optical communication module of the firecracker terminal and controls the electronic fuse module to start to ignite the firecracker body B1; The electronic fuse module can be started with a fixed-time delay to ensure that the igniter moves to a safe area and improve safety; the delay time can also be freely set by the igniter through the mobile terminal A to achieve effects such as countdown fireworks and programmed fireworks, increasing the fun; Step 7: A fireworks setting record database is constructed in the cloud server C. After the firecracker body B1 is ignited, the igniter's identity information, the model of the fireworks terminal B, and the geographical coordinate information of the setting location are encapsulated and uploaded to the fireworks setting record database.
