Description

Technical Field

[0001] The present invention relates to the technical field of fireworks ignition, and in particular to a wireless fireworks ignition method and system. Background Art

[0002] Fireworks displays require fireworks to be ignited at a predetermined time and location, creating a designed pattern in the air. Existing fireworks ignition systems are master-slave systems that utilize RS485 wired communication. A control host connects to several ignition slaves via the RS485 bus, each capable of independently igniting the fireworks. Due to the limited communication range and number of devices on a single RS485 network, RS485 relays are often required to expand the network size and communication range.

[0003] During the fireworks show preparation phase, staff members create a pyrotechnics plan, essentially creating a firing schedule. This schedule primarily includes three fields: "position," "slave number," and "delay time." Once the schedule is complete, the delay time is written to the slaves, saved, and placed in their designated locations.

[0004] During ignition, the master device broadcasts the ignition command to the slave devices via the RS485 network. Upon receiving the ignition command, the slave devices delay the specified time according to their respective ignition schedules before igniting the fireworks. A single fireworks display requires hundreds of ignition slave devices deployed over a radius of several kilometers. Staff operate the master device from a safe area. The current system has the following main shortcomings:

[0005] 1. RS485 networking is inconvenient, and its communication distance and number of devices are limited. An RS485 network has a communication distance of approximately 1 kilometer and can accommodate approximately 100 devices. For a fireworks display, both the communication distance and the number of devices are insufficient, necessitating the use of repeater expansion. Laying RS485 communication cables over dozens of kilometers for a fireworks display is labor-intensive and prone to errors.

[0006] 2. Ignition timing consistency is not high. RS485 network communication has transmission delays, especially when using relays. The master's ignition command is forwarded through the relay, with a delay of about ten milliseconds. After the command is forwarded through multiple relays, the delay can reach tens of milliseconds. This causes ignition timing to be out of sync between the ignition slaves, affecting the performance.

[0007] 3. Slave ignition units cannot be positioned, making deployment and management inconvenient. During on-site deployment, ignition units with corresponding numbers must be placed in designated locations. In practice, this can easily lead to misplaced units or incorrectly numbered units. A fireworks show takes about a week to prepare, and during this time, there's a risk that the deployed ignition units could be accidentally moved or lost.

[0008] 4. The control host has limited functionality and a low level of informationization and intelligence. It cannot perform functions such as performance planning, performance project management, inventory management, slave positioning preview, and monitoring and alarming. Therefore, we propose a wireless fireworks ignition method and system to address these issues. Summary of the Invention

[0023] Furthermore, when performing on-site arrangement in S3, it is only necessary to place the wireless fireworks ignition slave at a designated location, and the wireless fireworks ignition slave uploads its own positioning information to the wireless fireworks cloud platform.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] Example

[0042] like Figure 1-5 As shown, a wireless fireworks ignition method proposed in one embodiment of the present invention includes the following steps:

[0043] S1: Create a new fireworks show project on the Wireless Fireworks Cloud Platform and fill in basic information.

[0044] S2: Design a fireworks show plan on the wireless fireworks cloud platform and generate a fireworks ignition schedule. The fireworks ignition schedule includes the location and delay time, eliminating the need for traditional slave numbering.

[0045] S3: Pick up the wireless fireworks ignition slaves and fireworks required for the performance from the Wireless Fireworks Cloud Platform, then arrange the wireless fireworks ignition slaves and fireworks on site and place them in the designated location; when arranging on site, you only need to place the wireless fireworks ignition slaves in the designated location, and the wireless fireworks ignition slaves will upload their own positioning information to the Wireless Fireworks Cloud Platform.

[0046] S4: The Wireless Fireworks Cloud Platform uses the slave positioning preview function to verify whether each wireless fireworks ignition slave is placed in place; the Wireless Fireworks Cloud Platform will monitor the location and operating status of the wireless fireworks ignition slave. When the wireless fireworks ignition slave is accidentally moved or the operating status is abnormal, an alarm will be issued.

[0047] S5: The wireless fireworks cloud platform sends an ignition schedule for each wireless fireworks ignition slave; the wireless fireworks cloud platform will send a delay time to each wireless fireworks ignition slave according to the correspondence between the position and delay time in the ignition schedule, and send time T1 to the wireless fireworks ignition slave arranged at location A, send time T2 to the wireless fireworks ignition slave arranged at location B, send time T3 to the wireless fireworks ignition slave arranged at location C, and so on. In this way, when arranging on site, you only need to place each wireless fireworks ignition slave in place, and there is no need to place wireless fireworks ignition slaves with fixed numbers in fixed positions, which reduces the workload.

[0048] S6: The wireless fireworks ignition slave receives the standard wireless clock to achieve clock synchronization.

[0049] S7: The wireless fireworks cloud platform issues a start command, and the wireless fireworks ignition slaves ignite fireworks according to their respective ignition schedules. At the start of the performance, the wireless fireworks cloud platform sends an ignition command to the wireless fireworks ignition slaves. The ignition command includes the ignition start time. Upon receiving the ignition command, the wireless fireworks ignition slaves start counting from the ignition start time and ignite the fireworks after a specified delay. For example, if the ignition start time included in the ignition command is 9:15 Beijing time, all wireless fireworks ignition slaves will start counting from 9:15 and ignite the fireworks after their respective delays. Because each wireless fireworks ignition slave receives a standard wireless clock, even if they receive the ignition command at different times, they can still guarantee the same ignition start time. Ignition timing accuracy can be controlled to within 0.01 milliseconds.

[0053] The wireless fireworks cloud platform includes a performance project management module, a performance project scheduling module, an inventory management module, a monitoring and alarm module, a slave positioning preview module, a slave ignition control module, and a database module. The database module signals connect the performance project management module, the performance project scheduling module, the inventory management module, the monitoring and alarm module, the slave positioning preview module, and the slave ignition control module. Users log in to the wireless fireworks cloud platform via an app or a web browser to remotely manage fireworks performances. This achieves a closed-loop management system for performance project management, performance plan scheduling, inventory management, slave positioning preview, and ignition control. When the wireless fireworks ignition system is in use, each wireless fireworks ignition slave communicates with the cloud platform via a 4G network. The ignition slave receives location signals from the satellite positioning system to obtain its current location. The ignition slave receives a wireless standard clock to obtain accurate time.
