Abstract
The invention discloses a heat battery activation time testing device, especially the device equipped on the missile ground of electricity and gas supply. The device comprises the framework, the striker trigger, the trigger electric machine and the photoelectric sensor. As testing, the laser signal launched by the photoelectric sensor passes through the through-hole on the striker trigger shell; after the trigger electric machine driving the striker trigger the striker strikes the fire cap on the grounded electricity and gas supplier and makes voltage of the inner heat battery increase rapidly and meanwhile blocks the laser signal through the hole; the point is the sampling starting point of the computer and the voltage set is the terminal point; the calculation of the computer gets the activation time. The strong points of the invention are: convenient signal collection, good repeating, agile reaction, non interference, and high precision and good reliability.
Description
Technical field:
The present invention relates to a kind of device for measuring activation time of thermal cell, especially be installed in device for measuring activation time of thermal cell in the guided missile surface power supply feeder.
Background technology:
Guided missile surface power supply feeder is made up of refrigeration source of the gas and thermobattery two parts, and the power supply air feed of this device activates back output by clashing into its igniter cap with it.When MISSILE LAUNCHING, wish the utmost point of thermobattery after percussion cap electronic circuit on refrigeration source of the gas and bullet immediately in the short time, ignitions etc. are supplied with required voltage.This utmost point short time is called activationary time, and promptly to bump against igniter cap be initial to striker, and the magnitude of voltage that sampling obtains is the time that termination continued from the magnitude of voltage that 0V progressively rises to setting.For guaranteeing the quality of guided missile surface power supply feeder, in batch process, need the thermobattery in this device is done the sampling Detection of activationary time.Existing determinator is placed the frame of surface power supply feeder and striker trigger and trigger motor by one and is formed.Measure one of activationary time method, be to adopt the mode that vibration transducer is attached to striker trigger outside surface, the vibration signal that is produced when striker percussion cap is as computer sampling starting point signal, the deficiency of this method is the signals collecting instability, and especially the cryogenic conditions lower sensor coheres difficulty; Two of method is to adopt the close striker trigger of sound meter, and the voice signal that is produced during with striker percussion cap is as computer sampling starting point signal, and its deficiency is the voice signal interference problem.Three of method is to adopt the torque sensor or change to be installed on the trigger motor apart from speed probe, and the torque changing value when rotating by the trigger motor is determined the sampling starting point, and its deficiency is that equipment volume is big, is not suitable for the test of ground power supply feeder; Four of method is the current sensors that are installed in series at the motor power place, and the electric current changing value when rotating by motor is determined the sampling starting point, and its deficiency is that current sample ripple signal is big, interference is big.
Summary of the invention:
The purpose of this invention is to provide a kind of device for measuring activation time of thermal cell, it have signals collecting convenience, good reproducibility, Installation and Debugging easily, be quick on the draw, noiseless, advantages such as correctness is high, good reliability.
For achieving the above object, the present invention includes: frame, striker trigger and the trigger motor of placing the surface power supply feeder, striker trigger one end is fixed on the end face at surface power supply feeder igniter cap place, the other end connects the trigger motor by the trigger sleeve pipe, the trigger motor is fixed on the frame, it is characterized in that: also comprise photoelectric sensor, have a through hole at the striker trigger near on the housing at surface power supply feeder igniter cap place, the laser signal that photoelectric sensor penetrates passes through hole, and the signal of photoelectric sensor is by computer A/D plate input computing machine.Before the test, make photoelectric sensor send laser signal and pass through hole; Behind trigger motor-driven striker trigger, igniter cap on the striker colliding surface power supply feeder, the voltage of thermobattery is climbed fast, striker has stopped the laser signal by through hole simultaneously, with this point is the computer sampling starting point, with the magnitude of voltage that reaches setting is terminal point, and computer just can obtain activationary time as calculated.
Above-mentioned photoelectric sensor is that PicoDot is focusing.
The present invention is owing to adopt said structure, and the precision of the starting point of compared with prior art sampling significantly improves, and has overcome former method because judging point lags behind and has caused the big disadvantage of the activationary time error of calculation.In addition, the hole is simple owing to opening on the housing, and focusing photoelectric sensor volume again is small and exquisite, so cost of the present invention is low, and the Installation and Debugging wiring is easy.Simultaneously, focusing photoelectric sensor light beam is stable, and optical signal transmission is fast, and back level output can directly be connected with computer A/D plate, thus the present invention have signals collecting convenience, good reproducibility, be quick on the draw, noiseless, correctness is high, the advantage of good reliability.
Description of drawings:
Fig. 1, be cut-away view of the present invention;
Fig. 2, for the process flow diagram of computing activation time of the present invention.
Embodiment:
By shown in Figure 1, before the sampling test, earlier surface power supply feeder 1 is installed on the base of frame 6, striker trigger 2 one ends are fixed on the end face at igniter cap 2-5 place of surface power supply feeder 1, and the other end connects trigger motors 4 by trigger sleeve pipe 3, and trigger motor 4 is fixed on the frame 6.Photoelectric sensor 5 adopts PicoDot focusing, and is shelved on the carriage of frame 6, when photoelectric sensor 5 electric after, send a branch of red laser signal and pass the through hole 2-4 that opens on the striker trigger 2 housing 2-3, promptly finishing the preliminary work before the sampling test.In test, computing machine sends instruction, makes motor 4 rotate and drive trigger sleeve pipe 3 and makes striker trigger 2 begin to pull, and this computer-chronograph begins to gather the output signal of photoelectric sensor 5.After striker trigger 2 is pulled desired location, striker 2-1 under spring 2-2 effect, bump against rapidly igniter cap 2-5 a flash that, photoelectric sensor 5 red laser beams are blocked, computer acquisition this moment to the output signal of photoelectric sensor 5 as the activationary time starting point, immediately disable motor 4, start sampling to thermobattery voltage, electric current and pressure channel data.Sampling finishes, and can calculate and obtain activationary time.Computer software is finished flow process that activationary time calculates as shown in Figure 2.
