摘要： PROBLEM TO BE SOLVED: To prolong service life by connecting a layer 1 monitor circuit to a digital line so as to make intermitted operation and activating a layer 2 processing circuit when a signal is detected on a line thereby reducing power consumption. SOLUTION: A battery 37 supplies power to a layer 1 monitor circuit 23 intermittently and the circuit 23 confirms the presence of a signal on a line. When a signal S1 making a call from a center to a meter 15 and the circuit 23 detects the signal S1 at a prescribed time, a layer 2 processing circuit 27 is arisen to interrupt power supply to the circuit 23 and the battery 37 supplies power to a monitor circuit 25. Then the circuit 25 compares a voltage resulting from dividing a voltage of the signal S1 by resistors 43, 45 with a reference voltage at a comparator 49 and when the divided voltage is the reference voltage or over, the signal is fed to a CPU 29. Then the CPU 29 regards there is a margin in the supplied power and discriminates local feeding to be available. The local feeding is tused and power is supplied to each circuit in an I-NCU to reduce the load of the battery 37.

摘要： PROBLEM TO BE SOLVED: To provide a load survey meter system which obtains load survey information of high precision and is simple in data processing. SOLUTION: When gas equipments 13 (13-1 to 13-n) start or stop operating, radio equipments 17 (17-1 to 17-n) on the sides of the gas equipments 13 send operation state information to a radio equipment 15 on the side of a microcomputer meter 3. The radio equipment 15 on the side of the microcomputer meter 3 receives the operation state information sent from the radio equipments 17 and sends it to the microcomputer meter 3. The microcomputer meter 3 generates gas consumption information from the amount of used gas passing through the microcomputer meter 3 and records the operation state information and gas consumption information at previously set intervals of time. The recorded operation state information and gas consumption information are sent to a center 11.

摘要： PURPOSE: To revise a direction of a supervisory equipment in a way that an intruder cannot predict by moving the supervisory equipment in a chaos way based on a chaos signal. CONSTITUTION: A chaos signal outputted from chaos signal generating circuits 2, 3 of a supervisory equipment driving device 1 is fed to a driver 8 via corresponding A/D converter and BPFs 4, 6 and 5, 7 and the supervisory equipment 10 is moved in terms of chaos via a servo motor 9 and its direction is revised. Through the revision of its direction in a chaos way, an intruder cannot predict the direction of the supervisory equipment and the intruder cannot get through against the supervisory equipment. Furthermore, the chaos signal generating circuit is easily configured by using nonlinearity of the circuit and the direction change of the supervisory equipment is moved smoothly and continuously by the control of the chaos signal and a load imposing onto the drive system is reduced.

摘要： PURPOSE: To eliminate the necessity of a built-in battery and to attain miniaturization and long service life by converting a signal transmitted from an alarm into prescribed voltage and using the voltage as a power supply for a transmitting part. CONSTITUTION: At the time of detecting gas leakage or the like, an alarm 1 transmits an alarm signal to a transmitter 3. At normal (monitoring) time, the alarm 1 transmits a 6V voltage signal to the transmitter 3, but at the time of detecting gas leakage or the like, transmits a 12V voltage signal to the transmitter 3. A step down converter 5 converts the signal sent from the alarm 1 into 3V voltage e.g. and always supplies the converted voltage to a transmitting part 7 as power supply voltage. A signal detecting circuit 9 detects an alarm signal sent from the alarm 1 and transmits the detected result to a telegraphic message information setting circuit 11. The circuit 11 prepares a telegraphic message for transmitting the generation of an abnormal state (gas leakage) and a modulating/sending circuit 13 modulates the message and sends an alarm signal from an antenna 15 as a radio wave.
