析することができる。Next, the effect of the above configuration will be explained. In order to determine the function of the rotary melon detection device including the electromagnetic pickup 3, first the diesel power generation equipment is started, and the start signal As the clock circuit starts, the frequency signals from the electromagnetic pickup 3 and lO are transmitted to the cable 4.
and 11 are input to the rotational speed detector 5 and the determination section 12, respectively. While the rotational speed of the diesel generator 1 gradually increases and reaches the rated speed, for example, 11000 rpm, the rotational speed detection rA5 inputs the frequency signal of the electromagnetic pickup 3 and sets the rotational speed to a set value 5etl (5096). When the value 5et2 (95%) is reached, the auxiliary relays 6 and 7 are activated to output the arrival signal S1 and the arrival signal S2, respectively.
is issued to the determination unit 12. Next, in the determination section 12, the rotational speed is detected by a separate electromagnetic pickup 10 using a separate system from the same detection gear 2 as the electromagnetic pickup 3, and the frequency signal is manually input. The rotational speed and time measured by this frequency signal are stored in memory and displayed on the rotational speed trend graph section 16 of the display section (3) as required by the operator. Also, the rotation speed reaches the rated speed,
For example, when a startup completion signal X2, which is a turn-on signal for a diesel generator power breaker on a startup control panel (not shown), is input, the clock circuit stops, and the measured time is displayed on the startup time display section 17c. In this process, the arrival signals Sl, S2 (
Set value 5 etl (50%) and set value S e t 2
(95 sweetfish) ) is manually input to the judgment unit 12,
The rotation speeds measured by the determination section I2 are displayed on rotation speed display sections 17a and 17b, respectively. At this time, the determination unit 1
If the error between the rotational speed measured in step 2 and that measured by the rotational speed detector 5 exceeds a predetermined range, it is determined that there is an abnormality in the function of the rotational speed detection device, and the υ information display section An abnormality is displayed on 18. Thereby, the operator can immediately determine whether the function of the rotational speed detecting device including the electromagnetic pickup 3 is functioning well, and can also easily know the start-up time of the diesel power generating equipment and the progress of the rotational speed until the start-up is completed. This makes it easy to check the functions of the rotational speed detection device and the diesel power generation equipment, and from this result, maintenance work can be carried out immediately if necessary. In addition, the outputs from the determining section I2 are as follows: iJ) section 1
4, and can be retrieved and analyzed at any time as needed.

転速度検出装置の判定装置。A speed detection means for detecting the rotational speed of the rotating body; and a speed detection means for inputting this output and outputting a rotational speed signal of the rotating body, as well as a starting and starting completion signal of the rotating body, and a rotational speed to be determined separately installed on the rotating body. A signal emitted by the detection device when the rotational speed of the rotating body reaches a preset setting value is input to determine the starting time of the rotating body and the rotational speed and setting value when the rotational speed reaches the setting value in the rotational speed detection device to be determined. A rotation speed characterized by comprising a determination means for outputting an alarm signal when the rotation speed at the time of arrival exceeds a predetermined range with respect to a set value, and a display means and a recording means for displaying the output of this determination means. Determination device for detection device.
