Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a measuring instrument having a timekeeping function, a counting function, and an arithmetic function.

[Prior Art] Conventionally, there are many single-function tt measuring instruments that have only a timekeeping function or only a counting mechanism, but there are currently no ttill instruments that have both a timekeeping function and a counting function.

Therefore, conventionally, for example, when trying to find out the number of products manufactured by a certain manufacturing machine per unit time in order to check the manufacturing capacity of the manufacturing machine, a measurer would hold a stopwatch in one hand and hold a stopwatch in the other hand. The work is complicated, as each person has to hold a counter in his hand and visually count the number of products while looking at both the stopwatch and the products coming out of the machine. There was a problem that this method was prone to occur and lacked accuracy.

In addition, especially when accurate tt measurement was required, two people were assigned to measure time and the counting was carried out by different people, but in this case, 11t11
Although the accuracy of the 111 value is maintained, it must be said that it is extremely inefficient.

(Object of the Invention) In view of the problems of conventional measuring instruments as described above, the present invention
The purpose of this invention is to provide an IT-side device that allows a single measurer to perform reliable 1t1' measurements from the front.

(Structure of the Invention) The mortuary of the present invention includes a counting/timekeeping circuit that receives input signals from various sensors and input signals from a key to perform counting and counting, and a counting/timekeeping circuit that receives input signals from a key. an arithmetic circuit that performs a predetermined arithmetic operation, and a counting or IU of the counting/timekeeping circuit;
The present invention is characterized in that it includes a display unit that displays the time M result and the calculation result of the previous wdM calculation circuit.

(Embodiment) FIGS. 1 and 2 show a Vt side device Z according to an embodiment of the present invention.
tJX, 7< has been done. This IF measurement device is a so-called pocket calculator with counting and timing functions added, and has a measurement calculation section, a keyboard section, and a display section 3.

As shown in the block diagram of FIG. 3, the IT measurement calculation section/is equipped with a sensor amplifier t2 that adjusts the input levels from various sensors that are selectively connected to the sensor jack 10 (FIG. 2);
an input selector q3 that selects a trigger pulse according to the connected sensor; a counting/timekeeping circuit ++ that performs counting and timing in response to sensor input and key input from the keyboard section λ;
an arithmetic circuit tS that receives key human power and performs a predetermined arithmetic operation;
B is a control unit that controls the input selector 3, the counting/timekeeping circuit ≠t, and the arithmetic circuit S according to key human power; and a register t that temporarily stores counting/timekeeping results and calculation results. Furthermore, it has an audio circuit 50 that outputs the control step signal in the counting/timekeeping circuit llq as sound.

The keyboard 2 is composed of a group of function keys ≠ and a group of operation keys 5, as shown in the first factor.

Further, the display section 3 displays the counting/timekeeping results and the calculation results.

In FIGS. 1 and 2, the reference numeral 10 indicates the input section 2/ of the cup-type tachometer, and the optical fiber-type photoelectric sensor 22.
, omnidirectional microphone 23, high directional photoelectric sensor with built-in laser diode, high directional microphone, contact input terminal 2 O, slit scan input sensor + 27, vibration sensor 2 I! This is a sensor jack for selectively connecting various sensors such as i' and pinpoint input sensor 29. Also, the symbol l/ is an earphone jack for connecting 20, /2 is a counting push button, /3 is a power switch, /≠
is an rqm microphone, /S is a built-in photoelectric sensor, and /A is an 8 for adjusting the input level of the sensor amplifier t2.
The M dial /7 is an indicator light that detects the input state of the sensor amplifier Ko2.

Next, the functions and usage of section key group 1, calculation key group S, and push button /2 will be briefly explained.

First, the calculation function is performed by appropriately operating the calculation key group S, as is conventionally known.

In addition, the clock function and alarm function are as conventionally known (TM
This is performed using ME key llb and operation key group j.

When using it as a stopwatch, operate the LAP key≠C and the TIME key in the function key group t. At this time, the time is displayed on the display section 3.

Next, when using it as a counter, in this case, the function keys are operated according to the connected sensor. That is, first, C0UNTE of the function key group
Press R key d. Next, input selection is performed. That is, when using the push button 12 for counter input, press the MANUAL key llb, when using the photoelectric sensor, press the 0PTICAL key 4i, and when using the microphone, press the MIC key II.
When using j as a contact input, set the SW key tk, and when using it as a vibration sensor, set the G key g.

If you set the MANUAL key IIh, it will now count only when push button /2 is pressed, but if you set other function keys, the count will start from when push button /2 is pressed, and when push button 12 is pressed again. Counting ends when the count is reached. Also, normally it counts when the input is ON, but
If you want to count when the input is OFF, press the INV key l17
! Just press .

When used as a tachometer, after setting the function to TACHO%-μe, input selection is performed in the same manner as when using the counter.

In this case, the input is obtained and the result is immediately displayed on the display section 3, but since the display mode is normally set to H, if you want to display Vpm, press the MODE key jiff.
Press. Thereafter, each time the MODE key IIf is pressed, the display mode is alternately switched between town and rpIll.

Furthermore, as an application example of this VTTM device 2, for example, the omnidirectional microphone 23 is used to measure the pulse rate, the high directional microphone 211 is used to monitor the exhaust sound of a running motorcycle, From now on, we will measure the engine speed, count the number of birds using the slit scan 27, count the number of stars using the highly directional photoelectric sensor 21I, and use the vibration sensor 2 to measure the number of birds, for example on the knee. You can attach it to your device and walk, and measure the number of steps you take based on the number of vibrations.

Next, we will calculate the operation of the measurement calculation section using a photoelectric sensor.
Taking as an example the case of measuring the number of products produced in 10 minutes, first, the 0PTICAL key 4Zi is set by key operation, so the input selector Hiro 3 switches the control unit to the photoelectric sensor amplifier according to the command from Party B. A predetermined pulse signal is output to the counting/timekeeping circuit II side. Also, set the timer to one minute by key operation.

In this state, press the button l,! When is pressed, counting and timing start simultaneously, and the counting results are displayed on the display section for each count based on the output of the counting/timekeeping circuit tII. When - minutes have elapsed, a count stop signal is output from the timer to the counting/timekeeping circuit to stop the counting operation, and the control section <2+ is returned to the input mode from the keyboard section -.

At this time, the display section 3 is displaying the final count value.

This value is the count value (number of products) for one minute.

Furthermore, the register lIr is shared for counting/timekeeping and calculation, so if you want to know the number of products per second, for example, press the calculation key again.
When 9 is pressed, the calculation is performed and the result (ie, the number of products per second) is displayed on the display section 3.

Note that since signals such as counting start, counting end, and trigger pulse are output from the counting/timekeeping circuit Ill to the audio circuit 50, by connecting the earphone 20 to the audio circuit 50, these signals can be transmitted from the earphone 20. It is possible to hear it as a sound.

[Effects of the Invention] The measuring instrument of the present invention has a counting/timekeeping circuit that performs counting and timekeeping by receiving input signals from each blood sensor and an input signal from a key. It is possible to perform counting and timing at the same time with simple operation, and it is possible for one person to use two measuring instruments at the same time, such as an instrument that only has a counting function, and an instrument that only has a timing function. Moreover, compared to the case where two measurement operators work as a pair and each operate a measuring instrument, there is an effect that the reliability of measurement results and the efficiency of measurement work can be improved at the same time.

In addition, since it is equipped with an arithmetic circuit in addition to the counting/timekeeping circuit, it is possible to perform predetermined operations on counting/timekeeping results on the spot and display them as counting/timekeeping results of different dimensions, making it possible to display more diverse results. Another effect is that accurate measurement data can be obtained.
