(1) In order to enable the ignition pulse acquisition adapter to work independently without an external power supply in an external field environment, a power supply mode with a built-in lithium battery is adopted. Meanwhile, in order to effectively master the state of the lithium battery and the safe and reliable work of the ignition pulse acquisition adapter, a power management unit is designed.
(2) The ignition pulse signal detection unit takes a low-power-consumption microprocessor STM32 as a core, a built-in timer and an ADC module of the ignition pulse signal detection unit are used for quickly and accurately measuring the characteristic parameters of the ignition pulse signal, and a pulse signal detection circuit is divided into an optical coupling isolation circuit, a signal conditioning circuit and a pulse signal acquisition circuit.
a. A photoelectric coupling circuit. The signal to be detected is a direct current 28V ignition pulse, and the on-load detection is carried out on the signal to be detected through a high-power resistor in the signal acquisition device. In order to avoid the influence of the ignition pulse sequence on a post-stage circuit, the ignition pulse is firstly isolated and shaped by photoelectric coupling and then input into an external interrupt I/O port of a microprocessor.
b. A signal conditioning circuit. The ignition pulse signal passes through the front end load resistor and the photoelectric coupler, is amplified by the signal amplifying circuit and then is sent to the A/D conversion module of the microprocessor. The amplifying circuit is selected from OP291 type low noise, low temperature drift and single power supply operational amplifier. The operational amplifier has a wide input voltage range of 2.7-12V and a wide working temperature of-40-125 DEG C
c. Pulse signal acquisition circuit. The ignition pulse signal detection circuit takes a low-power consumption microprocessor STM32F103VCT6 as a core, 8 timing/counters and a real-time clock RTC are arranged in the ignition pulse signal detection circuit, and an STM32 has 5I/O ports: each port is provided with 16 pins, all the ports have external interrupt capacity, 18 12-bit A/D converters are integrated, each parameter of the pulse signal can be detected at high speed, the pins of the ports are distributed to GPIO or analog input through configuration, the requirement of pulse characteristic acquisition can be completely met, and the requirement of rapid and precise measurement of ignition pulse signal characteristic parameters can be met. The signals to be collected by each ignition pulse signal collecting adapter in real time are as follows: 12 ignition pulse signals and 1 bullet type identification signal. The 6 ignition pulse acquisition adapters count 72 ignition pulse signals and 6 bullet type identification signals. Because the pulse width and the interval of the ignition pulse signal are at the minimum of millisecond level, the firing ignition pulse of 12 electrodes adopts interrupt response (12-way independent GPIO), and the interrupt processing program is utilized to complete the analog-to-digital conversion work of the waveform characteristic parameters of the ignition pulse and the amplitude of the ignition pulse, so as to ensure that the real-time requirements of the interrupt response and the data acquisition are met.
(3) The filter code receiving unit sets filter codes for the ignition pulse signal acquisition adapter receiving host, stores the filter codes in the E2PROM, and reads the filter codes from the wireless transmission unit when the wireless transmission unit is electrified every time, so that the corresponding Zigbee network is added, and the collision of the ignition pulse signal acquisition adapters among a plurality of in-situ detection systems in a certain area is avoided.
The specific working process comprises the following steps:
before the airplane takes off, the ignition pulse adapter is connected into the emitter and locked, and the power supply is switched on; the ignition adapter is close to the portable display and control terminal, the microprocessor transmits the infrared ray carrying the filter code through the infrared transceiver to communicate with the portable display and control terminal, after the check interface receives and stores the filter code, the check interface returns confirmation information in an infrared mode, and at the moment, the buzzer in the handheld intelligent terminal sounds to inform the user of successful setting. Thus, it is ensured that the checking interface is conditionally selected to join the network, rather than all checking interfaces that are active are all joined to the network. Then the display control subsystem sends a signal to the transmitter through the controller, the signal is a 28V direct current signal at the moment, in order to ensure normal operation of all equipment of the system, the input signal needs to be connected with a load resistor for voltage reduction, the signal is transmitted to the microprocessor after isolation shaping and operational amplification through photoelectric coupling, the rapid and accurate measurement of ignition pulse signal characteristic parameters is completed by utilizing a timer and an ADC module which are arranged in the microprocessor, and a signal measurement result is displayed on the portable display control terminal through ZigBee communication. Therefore, the acquisition, the digitization and the characteristic parameter extraction of the input ignition pulse signal are completed, whether the circuit is smooth or not is obtained through analysis, and the result is timely fed back to the display control subsystem, so that whether the foil strips and the infrared interference bullets can be normally launched or not is known in real time.

The position-snapping signal converter 6 comprises a power management unit, a wireless transmission unit, a filtering code receiving unit, an ARM7 signal detection unit, a signal conditioning unit and a signal shaping unit; the power management unit, the wireless transmission unit and the filter code receiving unit are the same as the related modules in the ignition pulse acquisition adapter 5 in structure and principle.
(1) The ARM7 signal detection unit and the emitter 7 are respectively connected with the CFDS controller 3 through a three-way connector, and the CFDS controller 3 and the emitter 7 form a loop so that the detection unit realizes signal sampling.
(2) The signal conditioning unit amplifies and filters the signals and converts the signals into digital quantity signals which can be accepted by the ARM7 signal detection unit through optical coupling isolation, and the signals can be mainly classified into three types: switching value signals, analog quantity signals and Ethernet signals;
a. and after the on-off signal is subjected to level through an optical coupler, the on-off signal is buffered by an input chip and then is input into a GPIO of a TMS570 microprocessor for collection.
b. The analog quantity signal is output by the electronic switch through resistance voltage division by using a foil strip infrared throwing system interface power supply.
c. The Ethernet signals are interacted with the Ethernet protocol chip through the SPI interface, and the Ethernet communication is realized. Because the sampled signal is a weak signal of millivolt level and is in a positive state value and a negative state value, the signal is amplified firstly, and the structure function is adopted.
(3) During the bullet quantity inspection, a signal is output to the photoelectric coupler through the RC filter circuit, and the signal is shaped by the signal shaping unit and then transmitted to the ARM7 signal detection unit for collection. During bullet type identification, the + 5V/suspension signals are distinguished through the shaping of the reverser, and the signals are sent to a post-stage acquisition circuit for inspection and identification.
The specific working process comprises the following steps:
the aircraft takes the bullet to take off the back, the switch-on plays a position signal converter power, play a position signal adapter and lie in between machine-carried foil strip/infrared interference bullet input system controller and the transmitter, it is close to portable demonstration accuse terminal to play a position signal converter, microprocessor carries the infrared ray and the portable demonstration accuse terminal that filter the sign indicating number through infrared transceiver transmission and communicates, after the inspection interface accepts and stores the filter sign indicating number, can return the affirmation information through infrared mode, bee calling organ in the hand-held type intelligent terminal this moment rings and tells the user to set for successfully. Thus, it is ensured that the checking interface is conditionally selected to join the network, rather than all checking interfaces that are active are all joined to the network.
Then the display control subsystem sends a signal to the emitter through the controller, the ignition contact signal is a weak direct current voltage signal, when in a position detection mode, the ignition contact signal of the emitter is a ground signal of (-10 to-24) mV when being normal, therefore, the ignition contact signal needs to be amplified, then the signal is converted into a digital quantity signal (comprising a switching quantity signal, an analog quantity signal and an Ethernet signal) acceptable by ARM7 through photoelectric coupling and switching quantity conversion, and the acquisition of different position signals is realized according to different position conditions (the type of the bullet, the number of the non-bullet, the success of the bullet, the failure of the bullet, and the like) in the emitter. And the signal measurement result is displayed on a portable display control terminal through ZigBee communication, the acquisition, the digitization and the characteristic parameter extraction of the input spring position signal are completed, and the result is timely fed back to a display control subsystem, so that the switching of an ignition contact signal and a spring type identification signal in the transmitter is completed on the premise of not damaging the original connection relation.
The portable display control terminal needs to perform a large amount of data interaction with the distributed ignition pulse signal acquisition adapter, display pulse waveforms in real time or count pulse characteristic parameters through a table. Due to the high requirements on real-time performance and rapidity, an object program design idea is adopted in the design process. In an application program, a multithreading technology is adopted to realize the working logic of the in-situ detector and process, display and store data in real time.
