Signal wire is crossed with ignition system logical gate (2) to be connected, ignition system logical gate (2) by cable respectively with high pressure or high energy
Igniter (3), igniter fuel air valve (4), altar lamp fuel air valve (5) are connected, control high pressure or high-energy igniter (3) igniting
And igniter fuel air valve (4), the switch of altar lamp fuel air valve (5), the ignition system logical gate (2) is PLC controls
System processed, with fault-tolerant, self-checking function, whole Iganition control system is configured by certain logical construction.
In above-mentioned technical proposal, it is preferable that igniter fuel air valve (4) outlet passes through pipeline and high pressure or high energy point
Firearm (3) is connected, and altar lamp fuel air valve (5) outlet is connected by pipeline with altar lamp (6).
In above-mentioned technical proposal, it is preferable that the logical construction is：Ignition signal takes release pipe network temperature, pressure, key
These three signals of safety valve jumping up, logical relation selects two 2oo3 for three, i.e., the pipe network temperature that ought release, pressure and key safety valve rise
Jumping has any two to provide when releasing signal in these three signals, be considered as occurring in that operating mode of releasing；Ignition system logical gate
(2) 1oo2, i.e. logical gate is taken to have the parallel section of two groups of independence for two, any part provides firing action signal can
To start follow-up firing action；High pressure or high-energy igniter (3) set redundancy；Igniter fuel air valve (4), altar lamp fuel gas
Valve (5) is all provided with bypass in parallel.
The present invention can effectively improve igniting system using the executable portion of various ignition signal, high reliability PLC and redundancy
The reliability of system, reduces torch operation risk, achieves preferable technique effect.

Embodiment
【Embodiment 1】
A kind of ignition controlling system as shown in Figure 1, including ignition signal sensor (1), ignition system logic section
Divide (2), high pressure or high-energy igniter (3), igniter fuel air valve (4), altar lamp fuel air valve (5), ignition signal sensor
(1) release pipe network temperature, pressure, key safety valve take-off signal are received, and passes through signal wire and ignition system logical gate (2)
Be connected, ignition system logical gate (2) by cable respectively with high pressure or high-energy igniter (3), igniter fuel air valve (4),
Altar lamp fuel air valve (5) is connected, control high pressure or high-energy igniter (3) igniting and igniter fuel air valve (4), altar lamp
The switch of fuel air valve (5), the ignition system logical gate (2) is PLC control system, with fault-tolerant, self-checking function, entirely
Iganition control system is configured by certain logical construction.Igniter fuel air valve (4) outlet passes through pipeline and high pressure
Or high-energy igniter (3) is connected, altar lamp fuel air valve (5) outlet is connected by pipeline with altar lamp (6).The logical construction
For：Ignition signal takes pipe network temperature of releasing, pressure, key safety valve take-off these three signals, and logical relation is 2oo3；Igniting system
Logical gate (2) of uniting is 1oo2；High pressure or high-energy igniter (3) set redundancy；Igniter fuel air valve (4), altar lamp fuel gas
Valve (5) is all provided with bypass in parallel.
When device is released, safety valve jumping up, gas of releasing enters torch after point flow container (7), water sealed tank (8)
(12).When releasing, release line pressure and temperature is to rise, ignition signal sensor (1) uses 2oo3 modes, provides device
The signal discharged, and pass to ignition system logical gate (2).
Ignition system logical gate (2) is using with redundancy, the technical grade PLC of self-diagnostic function, it is ensured that signal transacting
Accuracy.
The igniting model that ignition system logical gate (2) is provided passes to high pressure or high-energy igniter (3), igniter fuel
Air valve (4) and altar lamp fuel air valve (5), start high-energy ignition, and high pressure or high-energy igniter (3) light altar lamp (6) afterwards,
Complete whole firing action.
【Comparative example 1】
According to the condition described in embodiment 1, ignition signal only has a kind of mode of pressure sensor.Torch gas contains a large amount of
Graininess component such as carbon granules or crystallization, the impulse mouthful of easy retaining pressure sensor.When device is released, due to pressure sensing
Device impulse mouthful is blocked, it is impossible to monitor that pressure relief system changes in time, also just the process of releasing can not be timely responded to,
Ultimately result in can not the system of starting ignition in time light altar lamp and torch.
【Comparative example 2】
According to the condition described in embodiment 1, logical gate uses general PLC, without redundancy and self-diagnostic function.Work as biography
Feel part detection to the process of releasing simultaneously output alarm signal is to logical gate when, logical gate should be according to the alarm of transducing part
Signal makes firing command, but due to logical gate itself fail, sensing is reported without standby logical calculated part again
Alert signal is handled, and causes firing command not provide in time, influences firing action.
【Comparative example 3】
According to the condition described in embodiment 1, high pressure or high-energy igniter do not set redundancy, or igniter fuel air valve, length
Bright lamp fuel air valve does not set bypass.When logical gate provides firing command, because high pressure or high-energy igniter break down,
High-tension electricity can not be produced or high energy electricity is lighted a fire, cause loss of ignition；Or due to igniter or the event of altar lamp fuel air valve
Barrier, causes gas circuit to open in time, can also cause loss of ignition.
