摘要： PROBLEM TO BE SOLVED: To provide an estimating method and device for an insulator dirt amount by dynamic adjustment, utilizing a measured value of a pilot insulator, rationally correcting an estimation value of the insulator stain amount, and dynamically rechecking this estimation value in each measurement, so that high accurate measurement can be performed. SOLUTION: A stain dirt estimation value on an actual insulator 10 obtained by calculation of a meteorological data is corrected by using a pilot insulator 5, a dirt amount on the actual insulator is estimated. Correction is performed by a formula, (actual insulator stain amount) = (actual insulator dirt amount estimation value obtained by calculation from meteorological data) + (pilot insulator dirt amount measured value) - (pilot insulator dirt amount estimation value obtained by calculation from meteorological data). Here, from an obtained measured data, a regression formula is obtained in each correction, this operation is repeated to be used in dynamic adjustment of an estimation value of a stain amount in the actual insulator in the next time, reliability is automatically improved.

摘要： PURPOSE:To prevent the stoppage or divergence of the vibration of a piezoelectric vibrator and suppress measurement errors by directly obtaining the quantity of a contaminant stuck to an outdoor structure as an aging change, continuously measuring the quantity of the stuck contaminant, and obtaining continuous data. CONSTITUTION:A piezoelectric vibrator 4 is fitted on the surface of an outdoor structure 1, and the resonance frequency of an oscillating circuit 11 connected to the piezoelectric vibrator 4 is detected by a frequency counter 12. When a contaminant is stuck to the detection face 4a of the piezoelectric vibrator 4 and a load is applied, the resonance frequency of the oscillating circuit 11 is changed in response to the quantity of the contaminant. The quantity of the stuck contaminant is obtained by an arithmetic section 13 based on the change of the resonance frequency. The center section and outer periphery section of the vibrator 4 are covered with a shielding body, and the quantity of the contaminant is accurately measured.

摘要： PURPOSE:To save power consumption, by providing a transmission-period setting timer circuit having minute capacity, which issues a transmitting command at every specified period, in a temperature observing apparatus forming a unitary body together with an inserting tube including a temperature sensor, which is inserted into a piled material such as coal, and cutting a current during the period except for the time of transmission. CONSTITUTION:An inserting tube 2 incorporating a temperature sensor 3 is inserted into a piled material such as coal. The output is sent to an amplifier circuit 8 compris ing an amplifier part 6 and a data conversion part 7. The temperature data signal S3 from the circuit 8 is sent to an antenna 14 through a transmitting circuit 10 in a transceiver circuit 9, a transmitting part 12b of a radio 12 and a distributer 13. The signal is transmitted to a temperature receiver device 21 from an temperature observing apparatus 1. A call signal S1 from the device 21 is received by the radio 12 in a case 4. A signal S2 from a call detection timer circuit 15 is outputted. A transmitting-period setting timer circuit 16 having minute capacity receives the signal S2 and sends a current to the circuit 8 through a control circuit 17. The current supply from a power source part 18 to the sensor 3, the data conversion part 7 and the trans mitting part 12b is cut except for the transmitting period. Thus the power consumption is saved and maintenance and control are facilitated.
