In addition, the technical features involved in the respective embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1:
as shown in fig. 1, the ignition device capable of automatic repair in the embodiment comprises an ignition circuit and a shell, and is characterized by further comprising a control circuit; the control circuit consists of a control switch 2, a control processor 1 and an electric energy pulse detection sensor 3; the functional modules of the ignition circuit are all configured in duplicate, and the same functional modules are connected in parallel and then connected in series with other functional modules, wherein the parallel input ends of the same functional modules are respectively provided with a control switch 2, and the control switch 2 is used for switching one of the two same functional modules to a working channel of the ignition circuit according to a control signal of a control processor 1; the tail end of the ignition circuit is provided with an electric energy pulse detection sensor 3 which is used for detecting the high-voltage electric energy pulse output by the ignition circuit and transmitting the detection information to the control processor 1; the control processor 1 is configured to periodically receive the detection information, determine whether the ignition device is normal according to the detection information, control the control switches 2 to sequentially switch when the ignition device is determined to be abnormal, and control the control switches 2 to keep the current state when the ignition device is determined to be normal.
In this embodiment, the functional modules of the ignition circuit are backed up by both sides, which means that two sets of identical functional modules are used to form the ignition circuit on the basis of the existing modular ignition device; and the same functional modules are connected in parallel and then connected in series to form an ignition circuit, so that each functional module in the ignition circuit has dual redundancy, and the ignition circuit integrally meets the crossed redundancy design. The control switches 2 are installed at the parallel input ends of the same functional modules, which means how many functional modules are in the ignition circuit, i.e. how many control switches 2 need to be configured. The control switch 2 is a controllable gating switch device, the function of which can be similar to that of a controlled single-pole double-throw switch, and the control switch is connected with the control processor, receives a control instruction of the control processor 1, realizes gating switching, and enables one of two same functional modules to be switched into a working channel of the ignition circuit. The working path of the ignition circuit refers to a circuit formed by connecting all the gated working modules, and the composition of the circuit is the same as that of the existing one-way ignition circuit. In the ignition circuit, when a certain functional module breaks down, the high-voltage electric energy pulse at the tail end of the ignition circuit is abnormal, so that the electric energy pulse detection sensor 3 is arranged at the tail end of the ignition circuit, whether a module fault exists in the ignition circuit can be detected by matching with the judgment of the control processor 1, when the high-voltage electric energy pulse is judged to be abnormal, the fact that more than one functional module breaks down is indicated, at the moment, the control processor 1 can send out a control instruction, the corresponding control switch 2 is switched, the backup functional module is switched into a working circuit, the functional module with the fault is isolated, and the automatic restoration of the ignition device is realized. The principle of the control switch 2 for switching in sequence is as follows: because the control processor 1 receives the detection information periodically, when the high-voltage pulse is detected to be abnormal for the first time, the control processor 1 controls one of the control switches 2 to switch, when the high-voltage pulse is detected to be abnormal for the next period, the next control switch 2 is controlled to switch until a certain period is detected to be normal, the state of the control switch 2 is kept, and the switching is stopped, and on a time axis, the switching of different control switches 2 has a sequence which is preset when the sequence is initialized, so when the ignition circuit is abnormal, the switching of the control switches 2 is performed in sequence. It should be noted that, due to different damage conditions of the functional modules, sometimes, one or more control switches 2 may not need to be switched, and the ignition circuit is normal; sometimes, one or more control switches 2 may need to be switched many times before the ignition circuit can be restored to normal. The redundancy access and the sequential switching of the function modules are respectively controlled, so that a working channel meeting the function requirement of the ignition circuit can be always formed as long as the extreme condition that certain function modules are completely damaged does not exist.
The principle is that after the current of the power supply is connected into the ignition device, the current is filtered, inverted, rectified, stored and discharged through the control switches 2 and the functional modules to form high-voltage electric energy pulses, and then the high-voltage electric energy pulses are transmitted to the ignition electric nozzle through the ignition cable. When the circuit works normally, the electric energy pulse detection sensor 3 transmits the detected high-voltage electric energy pulse signal to the control processor 1. After the control processor 1 judges that the signal is normal, the control processor does not send a control signal to the control switch 2, and the control switch 2 is kept to be connected to one of the two same functional modules by default, so that the circuit is kept working. When a functional module has a fault, the high-voltage electric energy pulse at the tail end of the ignition circuit is abnormal or absent, and when the electric energy pulse detection sensor 3 detects that the high-voltage electric energy pulse is abnormal or absent, the information is transmitted to the control processor 1. The control processor 1 determines the signal, and sends out a control signal to the control switch 2 after finding that the signal is abnormal. The control switch 2 switches each stage of input of the ignition circuit to the other one of the two same functional modules according to a fixed sequence until the normal high-voltage electric energy pulse is detected, and no control signal is generated, so that the automatic repair function is realized.
In the embodiment, redundancy design of each functional module is carried out in the ignition device, and an independent control switch 2 is arranged at the input end of each functional module, so that one functional module is selected from each functional module to be connected into a working channel; the detection sensor is arranged at the tail end of the ignition circuit, the state of the working module of the ignition device is automatically analyzed, and the control switch 2 is automatically controlled to switch the functional modules, so that when the internal functional module of the ignition device breaks down, the automatic switching of the functional modules can be realized, the fault functional module is isolated, the normal functional module is switched on, the automatic repair of the ignition device is realized, the reliability of the ignition device is improved, the maintenance time and the maintenance cost in the whole life cycle are saved, and the service life of the ignition device can be prolonged; through the one-by-one and sequential switching of the control switches 2 at all levels, when a plurality of functional modules of the ignition device are damaged, a complete working channel can still be formed, the function of the ignition device is realized, and the reliability of the ignition device is further improved.

And when the electric energy pulse detection sensor 3 has a fault or an automatic control logic fault, the cover does not need to be dismounted and the electric energy pulse detection sensor can be returned to a factory, the gating control is directly carried out by utilizing an external control signal, the quick repair of the ignition device is manually realized, and the maintenance time and the maintenance cost of the ignition device are further reduced.
