Detailed Description
Example (b): a high-precision electronic delay ignition circuit capable of communicating is shown in figure 1 and comprises a single chip microcomputer control circuit, and an energy storage capacitor charging circuit, a projectile ignition circuit, a delay trigger detection circuit, a clock circuit and a communication circuit which are electrically connected with the single chip microcomputer control circuit.
The single chip microcomputer control circuit receives the transmitting instruction and uploads the working state information through the communication circuit. And the energy storage capacitor charging circuit starts charging after responding to the transmitting instruction and transmits a charging feedback signal to the singlechip control circuit after the charging is finished. The projectile ignition circuit projectiles and ignites after responding to the charging feedback signal. And the delay trigger detection circuit is used for transmitting a delay trigger signal to the single chip microcomputer control circuit after detecting the mechanical action triggered by ignition and throwing. And the clock circuit responds to the delay trigger signal and then carries out delay timing, and transmits a delay control signal to the single-chip microcomputer control circuit after the delay timing is finished. The delay ignition circuit responds to the delay control signal and then carries out delay ignition.
The energy storage capacitor charging circuit adopts a large-current MOS chip as a switch to control the charging of the energy storage capacitor. When the circuit is electrified, the MOS chip is in a closed state, and the energy storage capacitor is ensured to be in an electroless state after the circuit is electrified, so that the safety of the circuit is ensured.
As shown in fig. 2, in the present embodiment, the energy storage capacitor charging circuit includes a MOS transistor Q1, a MOS transistor Q3, a diode D2, a diode D6, an energy storage capacitor C1, a resistor R7, and a resistor R9. After the diode D6 and the energy storage capacitor C1 are connected in series, one end of the diode is connected with the source electrode of the MOS transistor Q1, and the other end of the diode is grounded. The gate of the MOS transistor Q1 is connected to the drain of the MOS transistor Q3 through a resistor R7, the drain of the MOS transistor Q1 is connected to a power supply, and the diode D2 is connected in parallel between the gate and the drain of the MOS transistor Q1. The source electrode of the MOS transistor Q3 is grounded, and the grid electrode of the MOS transistor Q3 is connected with the charging control end of the singlechip and is grounded through a resistor R9.
It should be noted that the energy storage capacitor charging circuit may also be replaced with other circuits whose equivalent circuit principles are consistent, for example, a circuit formed by adding or deleting electronic devices or changing the device model and parameters.
The throwing ignition circuit and the delay ignition circuit can simultaneously or independently adopt a large-current MOS chip as a switch to carry out triggering control on the resistance of the ignition head. When the circuit is electrified, the MOS chip is in a closed state, so that the ignition head can not act after the circuit is electrified, and the safety of the circuit is ensured. The current of the whole circuit loop can bear 5.8 amperes (transient state 30 amperes), and is far larger than the firing current when the resistance of the ignition head is exploded.
As shown in fig. 3, in the present embodiment, the principle of the projectile ignition circuit and the delayed ignition circuit are the same, and the projectile ignition circuit is taken as an example for explanation. The projectile firing circuit includes a MOS transistor Q2, a resistor R8, and a firing head.

The delay triggering detection circuit can conduct a switch arranged in the module through the relief action of the physical security mechanism, and converts the mechanical action into the high and low levels of the detection switch to judge the timing starting point; the single chip microcomputer realizes the triggering of delay timing by identifying the high and low levels output by the circuit, and adopts the high and low levels (0 or 1) converted by the physical switch for judgment, thereby ensuring the accuracy of the starting point of timing and ensuring the delay precision.

The ignition head F2 is the ignition head of the delay ignition circuit.
As shown in fig. 5, the clock circuit is clocked by the MCU controller clock, the clock frequency is 8 mhz, and the effective resolution is 0.125 μ s, which is much higher than the deferred accuracy requirement. When the delay trigger detection circuit detects a delay trigger signal, the internal timer of the singlechip is used for timing according to the clock model provided by the clock circuit, so that the accuracy of delay timing is ensured.
As shown in fig. 6, the single chip microcomputer control circuit mainly includes a single chip microcomputer and a resistor and a capacitor, and a control program is loaded in the single chip microcomputer, thereby implementing predetermined logic control. In this embodiment, the model of the single chip microcomputer is GD32F130F8P6, and other models capable of achieving the same function may also be adopted, which is not limited herein.
In the present embodiment, the communication circuit employs a serial communication interface circuit. The whole delay ignition circuit in the utility model can be connected with an external transmitting device through a communication circuit. Taking missile launching as an example, the whole delay ignition circuit can be integrated on a launcher (missile body) and then connected with a corresponding launcher through a communication circuit. When the delay ignition circuit is powered on, the controller in the external launching device sends out a state query command, and when the delay ignition circuit receives the command, the self-checking information is transmitted back to the controller, so that the detection of the ammunition state is realized.
As shown in fig. 7, the transmitting device is configured with a power supply circuit for supplying power to the storage capacitor charging circuit. The power circuit mainly comprises a power IC and a filter capacitor and is used for providing working voltage for the system.
The working principle is as follows: the singlechip control circuit receives the transmitting instruction and uploads working state information through the communication circuit; and the energy storage capacitor charging circuit starts charging after responding to the transmitting instruction and transmits a charging feedback signal to the singlechip control circuit after the charging is finished. The ejection ignition circuit ejects and ignites after responding to the charging feedback signal; the delay trigger detection circuit is used for transmitting a delay trigger signal to the single chip microcomputer control circuit after detecting the mechanical action triggered by ignition and ejection; the clock circuit is used for delaying and timing after responding to the delay trigger signal and transmitting a delay control signal to the single-chip microcomputer control circuit after the delay and timing are finished; the delay ignition circuit responds to the delay control signal and then carries out delay ignition; on one hand, the delay time can be flexibly set, and the application range is wide; on the other hand, the functions of real-time binding of internal parameters, uploading of state information, uploading of self-checking information, encryption triggering and the like can be realized, and the safety and the reliability are high.
