Hereinafter, described in detail by the accompanying drawings as follows.

The activation time measuring device 3, the life time measuring device 4, and the voltage detecting device 5 are provided on the input side of the computer 2, which is operated by the keyboard 1 and stores a program capable of controlling all devices and reading data. And the A / D converter 6 and the reset device 7 are connected to enable data transmission and exchange, and at the output of the computer 2, the counter circuit 12-14, the relay driver 15, and the load The controller 17 is in contact with each other for data transmission, and an AND circuit (AND ₁ -AND ₂ ) is connected to an output signal of the reference time generator 11 and a start terminal of the counter circuit 12. An output is applied to the activation time measuring device 3, the life time measuring device 4, and the voltage detecting device 5, while each counter circuit 12-14 has an indicator for indicating the quantity, light, and determination (8). -10) is connected to the relay drive unit 15, and each device, measuring device and measurement conditions Capable of providing a relay and to apply a signal to the (RL ₁ -RL _7), the load control unit 17 is controlling the relay (RL ₅ -RL ₆₎ sikimyeo connected to a load 19, 20, the battery 18 input to the amplifier (OP _1), the voltage output and at the same time applied to the voltmeter 21 via the relay switch (SW ₁₎ via a relay switch _{(SW 4) (SW 3)} (SW '4) from and to its output It is connected to the A / D converter 6, and the relay switch SW ₃ is connected to the band pass filter 26 through the amplifier OP ₂ so that the indicators 27 and 28 light up according to the output situation. It is.

The following description will be made for each measurement item by the configuration as described above.

When the system is operated by operating the keyboard 1, all the devices connected to the data bus of the computer 2 are enabled (enable) and wait for the voltage from the battery 18 to be output.

At this time, when the battery 18 is fired from the launching device 16 to give the same conditions as when the shell is fired, the liquid bottle containing the electrolyte is destroyed by the impact and the battery 18 is operated due to the rotational force. Voltage is applied to various circuit devices in the fuse.

Therefore, immediately after the battery 18 is fired, the relay driver 15 sends a signal to make the relays RL _1- RL ₄ (RL ₇ ) operational, so that the conditions necessary for the measurement, that is, the relay switch SW ₁ (SW ₂ ). ) (SW ₃ ) (SW ' ₄ ) is connected to the appropriate contact point, and the relay switch (SW ₇ ) is connected to the on (on) state to operate the oscilloscope device (24).

Therefore, the voltage output from the battery 18 is applied to the voltmeter 21 through the relay switch SW ₁ so that the voltage output from the battery 18 is expressed numerically and the relay switch SW ₄ (SW ₃ ). It is input to the amplifier OP ₁ via SW ' ₄ and is appropriately attenuated by the output voltage of the battery 18 and applied to the A / D converter 6.

That is, the A / D converter 6 converts an analog signal, which is a voltage output from the amplifier OP ₁ , into a data signal that can be read by the computer 2, and is transmitted to the data bus to be transmitted to the data bus. It is delivered to the internal CPU.

The CPU compares the signal transmitted according to the program with the data set inside the ROM, and sequentially checks the loop of the active time measurement item, the lifetime measurement item, and the maximum voltage measurement item. The CPU sends a signal to the load control unit 17 every 5 seconds, 10 seconds, and 135 seconds by the self-time counter while the test loop rotates.

First, the clock signal is generated from the reference time generator 11 by the AND circuit (AND ₁ -AND ₃ ) and the counter circuit after the activation time, that is, the time from the launch of the fuse to the operation of the battery 18 until the prescribed output voltage occurs. (12) When the activation time measuring device 3 starts to operate by applying to the start terminal ST of 13 and a prescribed voltage is generated from the battery 18, the output data of the A / D converter 6 and the ROM ( When the data stored in the ROM is compared with each other and the specified voltage is reached, the computer stop signal is sent from the output terminal of the computer 2 to the counter circuit 12, and thus the activation time measuring device 3 is stopped at the stop terminal SP of the counter circuit 12. The counter stops the counter by outputting an interrupt signal so that the time until the prescribed voltage is output after the battery 18 is operated is displayed.

At this time, when the displayed time is out of the data range set in the computer 2, the indicator 8 lights up to visually determine that it is bad.

The following is the time until the output voltage of the battery 18 goes below the specified voltage when the current is flowed to the load connected to the battery 18 after the activation time, that is, the life time measurement item. Commands the load control unit 17 at the output of the computer 2 to drive the relays RL _5- RL ₆ so that the output 18 and the voltage from the battery 18 pass through the loads 19 and 20 for a period of time. .

Accordingly, the voltage through the loads 19 and 20 passes through the relay switches SW ₄ , SW ₃ , and SW ′ ₄ in the same manner as described above, and then attenuates at a predetermined ratio in the amplifier OP ₁ , thereby providing an A / D converter. It is input to (6), converted into a data signal, and applied to the computer (2).

At this time, the computer 2 compares and judges the signals of the A / D converter 6, and when the voltage is lowered after the activation time, that is, below the specified voltage, the signal is applied to the counter circuit 13 from the output terminal of the computer 2. As a signal thereof, an interrupt signal is sent from the stop terminal SP of the counter circuit 13 to the life time measurement window 4, and the time counter is stopped.

Therefore, the time held by the life time measuring device 4 falls below the specified voltage after activation, and the measurement result must be 150 sec or more to supply stable power to all circuit devices in the fuse. If the condition is not satisfied, the indicator 9 lights up to indicate that it is bad.

The following is an item that measures the maximum voltage and time until the output voltage of the battery 18 is output above the specified voltage at a constant load 19, 20 value, and load 19, 20 as in the above measurement item. As described above, the voltage of the battery 18 passing through) is transmitted to the A / D converter 6 via the amplifier OP ₁ , but when the output voltage of the battery 18 increases, the A / D converter ( The digital signal of 6) also increases.

Therefore, the computer 2 continuously measures the changing digital signal, and the counter stop signal from the CPU when the data set in the ROM, that is, the maximum voltage (36 V) is matched with the counter circuit 14. By applying the interrupt signal to the voltage detecting device 5 at the stop terminal SP, the maximum voltage (36V) output from the battery 18 and the time until the maximum voltage is displayed are displayed. If the maximum voltage set in is not output, the indicator 10 is turned on to indicate that the battery 18 of the measurement target is defective.

The following is an item that detects noise included in the output voltage of the battery 18 and checks whether or not it is defective.Regardless of a program during a test loop to measure the item in the computer 2, The output voltage of the battery 18 is appropriately attenuated by the amplifier OP ₂ via the relay switch SW ₄ (SW ₃ ), and then input to the bandpass filter 26 to determine the noise component contained in the battery 18. The noise is detected by setting up the band and passing or attenuating the noise. At this time, when the detected noise voltage reaches the highest and minimum 200 mV or more, the indicators 27 and 28 turn on to determine that there is a lot of noise. Will be determined.

On the other hand, the voltage of the battery 18 appropriately attenuated by the amplifier OP ₁ is applied to the current converter 25 to convert the voltage into a corresponding current, and is input to the oscillator graph device 24 and the oscilloscope device 24. ) Can be printed to the outside by recording the measurement data by converting the voltage of the battery 18 into a graph using photosensitive paper, the discharge time of the battery 18 has passed or the signal of the reset device 7 during the measurement The computer 2 stops all running programs and returns to the initial state.

All of the measurement items, namely, active time, life time, peak voltage and time, and noise component detection, must be within the reference setting range to determine that the battery 18 is of good quality.

As described above, the present invention imparts the same conditions as when the shell is fired by the launcher 16 in order to select only the high quality battery 18 used for the shell proximity fuse, and various items, that is, the battery 18 operate. The time until the specified output voltage occurs (activation time measurement item) and the resistance (ie, the loads 19 and 20) having a constant value after the specified voltage output until the current falls for less than the specified voltage for a predetermined time. The time (life time measurement item) and the voltage and time (maximum voltage and time measurement item) and noise detection item when the maximum voltage of the battery 18 is outputted by the program using the one-chip computer 2. It is a device capable of selecting a good quality battery 18 by quickly and accurately inspecting a large amount of battery 18 by allowing it to be measured.
