Technical Field
The utility model belongs to the technical field of ammunition dynamic measurement, and particularly relates to a sensor line detector and a dynamic measurement device.
Background
The existing sensor line detection method is characterized in that a shock wave overpressure data acquisition system is connected with a sensor and a sensor transmission line during a test, then the sensor is knocked, whether the data acquisition system receives data or not is observed, and whether the connection of the line is normal or not is judged. When the shock wave overpressure data acquisition system is used, a 220V power supply is needed for power supply, and a general shock wave overpressure test is field operation, so that power is often needed to be supplied by a generator, and the detection of a sensor line is certainly influenced if the generator can normally supply power. Therefore, the sensor detection method is time-consuming and labor-consuming in operation, has a plurality of external influence factors, and increases the time cost and labor waste of the projectile overpressure test.
The second existing sensor line detection method is to form a loop with the sensor line and use a multimeter to detect the on-off condition of the line. The detection method can only carry out line detection when the sensor is not connected, and the operation needs cooperation of a plurality of persons, so that the detection time is long. In case sensor line connects the problem, then the universal meter can't detect out the problem, need to change line connection during the experiment to the debugging time and the work load of sensor line have been increaseed.
The power adapter produced by Qishile company can detect whether the sensor loop is normal, but needs 220V power supply, the field operation is inconvenient, and the instrument is large in size and inconvenient to carry.

FIG. 2 is a schematic diagram of the detector circuit of the present invention.
Detailed Description
In order to make the objects, contents, and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention will be made in conjunction with the accompanying drawings and examples.
As shown in fig. 1 and 2, the sensor line detector provided by the utility model mainly comprises a detection button, a triode, a light emitting diode LED1, a light emitting diode LED2, a digital display microammeter, a 1.5V rechargeable battery, a 3V rechargeable battery and a power switch, and is an auxiliary device for detecting whether a sensor line arranged before overpressure of a shot shock wave has faults.
The positive electrode of the 1.5V rechargeable battery is connected with one end of a power switch, the other end of the power switch is connected with the positive electrode of a light emitting diode LED1, the negative electrode of an LED1 is connected with the base electrode of a triode, the collector electrode of the triode is connected with the negative electrode of a light emitting diode LED2, the positive electrode of an LED2 is connected with one end of a digital display microampere meter, the emitter electrode of the triode is connected with the negative electrode of the 1.5V rechargeable battery and one end of a detection button, the other end of the detection button is connected with the negative electrode of a 3V rechargeable battery, and the other end of the digital display microampere meter and the positive electrode of the 3V rechargeable battery are wiring terminals of a sensor circuit to be detected.
When the detector is used, a power switch is turned on to form a circuit loop, the 1.5V rechargeable battery supplies power, and the LED1 of the light-emitting electrode tube displays green, which indicates that the detector can work normally; connecting a sensor circuit, pressing down a detection button, conducting a c-e end to the sensor circuit when current passes through a b-e end of a triode to form a positive pulse signal, conducting a sensor loop, and changing the problem that the sensor loop cannot be measured into a measurable state; the LED2 shows the on, off and short circuit states of the sensor circuit by displaying different colors and emitting light or not, the green shows the sensor circuit is on, namely normal, the red shows the sensor circuit is short-circuited, the non-light shows the sensor circuit is open-circuited, meanwhile, the digital display microammeter connected in series displays the current value of the sensor circuit, and whether the sensor circuit is normal or not can be judged by the current measuring range of the measured value.
The detector of the utility model can be seen in that the c-e end is conducted to give a positive pulse signal to the sensor when the current passes through the b-e end of the triode by utilizing the three-level switch circuit, and the sensor loop is conducted to change the unmeasurable problem of the sensor loop into a measurable state. The LED is used for displaying a color red to indicate short circuit, the color green indicates normal, and the sensor circuit is disconnected if the LED does not emit light. Meanwhile, the digital display microammeter is connected in series to display the current of the sensor loop and provide a pulse signal for the sensor loop, but the current passing through the sensor loop is very small due to the weak conductivity of the sensor, and cannot be measured by using a common ammeter. Whether the sensor loop is normal is judged through three ranges of the measured values.
The device is small in size (100mm 50mm 20mm), convenient to carry and use, adopts 1.5 and 3V direct current rechargeable batteries as a power supply (once per month charging), saves energy, and solves the problem that no generator is arranged in a field test circuit.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
