Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fireworks ignition circuit and a simultaneous ignition circuit that is connected to an ignition operating circuit device and facilitates the launching of fireworks, created by the present inventor.

[Prior art]

As shown in Figure 5, conventional fireworks of this type are ignited by connecting and extending the positive and negative wires to a fireworks ignition device called an igniter loaded in a launcher tube A, and connecting these wires to a switch board. This is done by closing this switch after connecting to.

Now, to explain the launch of fireworks, as shown in Figure 6A, the fireworks launch sites are the central site a, which has the largest number of fireworks, and the fireworks launch site is located several tens of meters away on the left and right of central site a, in line with the launches at central site a. It is divided into several locations: the left site B and the right site C, where simultaneous launches take place, and the device site d, which is several 10 meters apart, with a launch tube installed at each site. For example, central site a has 60 lines, and other sites have 60 lines.
There were 10 pieces each. After that, the electric wire connected to the ignition ball B of each launch tube A is extended to the ignition command center E, and connected to the switch board C at each site. At this time, since there are many launch tubes at central site a, the number of electric wires is also large (for 60 launch tubes).
120 electric wires are required), so they are connected to several switch panels separately, and at remote sites such as rigging site d, they are connected to the switch panel C at that site.

After that, the fireworks will be launched at the central site a, and several people will work together to synchronize the ignition timing so that the fireworks will be launched or ignited at the same time from the left site b, right site c, and device site d.
The ignition timing is controlled by communicating with remote sites via radio, adjusting the ignition timing, and operating numerous switch panels.

As described above, launching fireworks requires a large number of people, and when launching fireworks at the same time from distant locations, communication must be made by radio, which is often inconvenient.

On the other hand, the inventor of the present invention proposed a practical method for use at sites where a large number of launch tubes are planted, such as the central site.
Fireworks ignition circuit related to No. 59-54686 and patent application 1986-
By creating the ignition operating circuit device according to No. 94553, the above-mentioned inconvenience could be alleviated to some extent.

That is _{, the} fireworks ignition circuit α _shown in _FIG . The ignition ball terminal that connects to the ignition ball terminal can also be energized; conventionally, the number of wires required to connect 60 ignition balls to the power source is 60.
×2 = 120 lines, but with this fireworks ignition circuit α, only 16 lines are needed from the central site a to the ignition command center e.
On the other hand, the ignition operation circuit device β shown in FIG. ₁ ~L′ ₁₀
and the negative lines L′ _A to L′ _F , the positive lines L″ ₁ to L″ ₁₀ of the ignition operating circuit device β, and the negative lines
If L″ _A to L″ _F are connected correspondingly, any ignition ball connected to the fireworks ignition circuit α can be energized by closing the ignition switch. Launches from the central site a, which used to be carried out using several switchboards, can now be carried out using a single ignition operating circuit device β by adopting the fireworks ignition circuit α. FIG. 6B shows this state.

However, even though the number of switchboards has been reduced and fireworks have become easier to set off, there is still a need for several switchboards, and there is also a need to communicate with distant sites, which can be said to be easy enough. It wasn't.

[Problem that the invention attempts to solve]

Therefore, in this case, after connecting the groups of ignition balls at the left site, right site, and setting site, etc., if the fireworks ignition circuit is relayed or directly connected to the ignition operation circuit device, the ignition operation circuit device can be connected to the ignition operation circuit device. The aim is to provide a simultaneous ignition circuit that allows simultaneous launches from each site in conjunction with launches from the central site using only one launcher.

[Means for solving problems]

An embodiment of the present invention will be described with reference to FIGS. 1 and 2. In the simultaneous ignition circuit γ of the present invention, the positive terminals 2 of a group of ignition ball terminals arranged in 10 horizontal rows are connected to 10 positive lines L ₁ to L ₁₀ through diodes 3 in the forward direction, while the negative terminals 4 is connected to a common negative line 8 which is connected to a common terminal 7 of a rotary switch 6 which has six negative lines LA to _{L F} connected to a group of selection contact terminals 5.

FIG. 2 shows a simple and portable terminal box 10 in which a terminal panel 9 containing a built-in simultaneous ignition circuit γ of the present invention is partitioned.
, 11 and 12 are 10 brass lines L ₁
~L ₁₀ and the six negative lines L _A ~ L _F are connected individually to the external positive connection terminal group and external negative connection terminal group for conventional electric wires, and 13 is the 10 positive lines L ₁ ~ _{L 10} and 6 negative lines L _A ~
A connection joint consisting of a group of external positive connection terminals 11' and a group of external negative connection terminals 12' for a 16-core cable that converges and connects L _F at once, 14 is a switching knob of the rotary switch 6.

[Effect]

Since the present invention is configured as described above, the fireworks ignition circuit α connected to the ignition operation circuit device β is connected to the 10 positive lines L ₁ to L ₁₀ and the six negative lines L _A to L _F of the simultaneous ignition circuit γ. 10 positive lines L′ ₁
〜L′ ₁₀ and six negative lines L′ _A to L′ _F corresponding to each other individually or all at once, and operate the switching knob 14 of the rotary switch 6 to switch and connect them to the desired position. For example, the rotary switch 6 is connected to the negative line L _D , the closing of the D'' stage ignition switch of the ignition operating circuit device β simultaneously energizes the D' stage ignition ball B of the fireworks ignition circuit α. The ignition ball 1' is energized.

Now, to explain the case where the simultaneous ignition circuit γ is used at an actual fireworks launch site, as shown in FIG. After connecting ignition ball 1' to 1, 10 positive lines L ₁ of simultaneous ignition circuits γ ₁ and γ ₂ of left site b and right site c
~L ₁₀ and the 6 negative lines L _A ~L _F are connected to the 10 positive lines L' _{1 ~} of the fireworks ignition circuit α at the central site a.
L' ₁₀ and six negative lines L' _A to L' _F are connected individually or collectively, and the simultaneous ignition circuit γ ₃ of the remote work site d is connected to the 10 simultaneous ignition circuit γ ₂ of the nearest right site c. Plus lines L ₁ to L ₁₀ and 6 minus lines
After connecting L _A to L _F individually or collectively, the switching knobs 14 of the rotary switches 6 are respectively switched to desired positions. For example, fireworks ignition circuit α
When launching fireworks from the left site b at the same time as the ignition ball of the A' tier, and simultaneously launching fireworks from the right site c and the setting site d at the same time as the ignition ball of the B' tier,
Switch and connect the rotary switch 6 of the simultaneous ignition circuit γ ₁ of the left site b to the negative line L _A , and also connect the rotary switch 6 of the simultaneous ignition circuit γ 1 of the left site b
The rotary switches 6 of the simultaneous ignition circuits γ ₂ and γ ₃ at the setting site d may be switched and connected to the negative line L _B , respectively. FIG. 4 is a circuit diagram at this time. (However, to simplify the explanation, the number of ignition balls at each site is reduced.) To explain the operation of the simultaneous ignition circuit γ based on this Fig. 4, first, the A″ ₁ of the ignition operation circuit device β. When the ignition switch is closed, the ignition ball _A'1 connected to the fireworks ignition circuit α at the central site a is energized.At the same time, the positive line L' ₁ of the fireworks ignition circuit α is energized.
, the ignition ball 1' of A ₁ of the simultaneous ignition circuit γ ₁ at the left site b is also energized. At this time, the ignition ball 1' of A ₂ is released by the action of the diode 3 interposed in the forward direction, so the current flows through the ignition ball 1' of A ₂ in the opposite direction and follows the positive line L ₂ to the fireworks ignition circuit. There is no possibility that the ignition ball B of A′ ₂ of α will be energized.
On the other hand, the simultaneous ignition circuits γ ₂ and γ ₃ installed at the right site c and the trick site d are fireworks ignition circuits α since the rotary switch 6 is connected to the negative line L _B.
Even if the positive line L′ ₁ is followed, a closed circuit is not formed, and no fireworks are ignited at the right site c and the setting site d. That is, the ignition operation circuit device β
When the switch _A''1 is closed, only the ignition ball _1' of A'1 at the center site a and the ignition ball ₁ ' of A1 at the left site b are energized at the same time, and fireworks are launched from two locations.

Next, when the ignition switch A'' ₁ of the ignition operation circuit device β is opened and the switch B'' ₁ is closed, the fireworks ignition circuit α of the central site a and the ignition ball B′ ₁ of the fireworks ignition circuit α are simultaneously fired at the right site c and the setting site. Simultaneous ignition circuits γ ₂ and γ ₃ of d
The ignition balls 1' of B ₁ and B ₁ are energized, but at this time, due to the action of the diode 3 interposed in the forward direction, the other ignition balls 1' are not energized, and the simultaneous ignition circuit of the left site b At γ ₁ , the rotary switch 6 is connected to the negative line _LA , so it is not energized.

That is, the ignition ball b of B′ ₁ at the center site a and the right site c.
Then, only the ignition balls 1' of B ₁ and B ₁ at the setting site d are energized, and fireworks are launched from three locations at the same time.

In this Fig. 4, the fireworks ignition circuit γ is connected to the ignition operating circuit device β via the fireworks ignition circuit α, but as shown in Fig. 3 B or C, depending on the topographical conditions of the launch site, It is sufficient to connect them in an appropriate manner, and in any case, simultaneous launches from each site will be performed by the ignition operating circuit device β.

〔effect〕

As mentioned above, the proposed simultaneous ignition circuit allows fireworks to be launched from each site at the same time as the central site by simply operating the ignition device by switching the rotary switch in advance according to the fireworks launch program. , only one worker is required for the launch operation, there is no need to synchronize the ignition timing with each site as in the past, and even if the site is far away, it can be connected to the same ignition circuit at the nearest site. Similarly, the ignition control circuit device β of the ignition control center
Since the fireworks are ignited by the fireworks, there is no need for wireless communication, which is extremely effective in saving labor, making fireworks easier, and centralizing and remote control.
