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.

摘要： PURPOSE:To reduce current consumption by allowing a receiver to intermittently monitor a control signal transmitted from a transmitter and intermittently turned on after receiving the control signal. CONSTITUTION:Since the transmitter transmits an intermittent signal S12 to be turned on for X sec and turned off for Y sec to the receiver at the time of receiving an abnormal state detecting signal sent from a gas detector, the current consumption of the transmitter can be suppressed to a low level. On the other hand, the receiver monitors the signal S12 sent from the transmitter at the interval of time T2, and when the signal S12 is ON at received input check timing, monitors the signal S12 continuously for regulated time T3. When the signal S12 is transmitted during the period of the time T3, the receiver sends a control signal S15 to a microcomputer meter. At the time of receiving the signal S15, the microcomputer meter executes processing such as the interruption of gas. Since the signal S12 is intermittently monitored for (X + Y) sec, the current consumption of the receiver can be suppressed to a low level.

摘要： PROBLEM TO BE SOLVED: To provide an automatic metering radio equipment in an automatic metering system that can set an ID at installation of the automatic metering radio equipment with a highly reliable and simple method. SOLUTION: When a storage section 56 stores no slave unit information and only a 1st operation setting is accepted, a control section 53 of a radio master unit 5 newly registers the slave unit information, and when the storage section 56 is already stored, the control section 53 controls the storage section 56 to overwrite the slave unit information only when a 2nd operation setting is accepted. Thus, so long as a 2nd operation is not applied to the radio master unit 5, accidental erasure of the slave unit information already registered can be prevented and the job reliability can be enhanced.

摘要： PROBLEM TO BE SOLVED: To provide a communication system, where an intermittent drive time interval for a PHS terminal is switched so as to enhance customer service and reduce a PHS terminal maintenance cost. SOLUTION: As soon as a gas plug closing command is sent, an intermittent drive time interval of a PHS terminal is switched from a time t1 (e.g., 6 hours) to a time t2 (e.g., 15 minutes), to reduce the waiting time. When receiving a gas plug open command, the plug opening processing is conducted in a comparatively short time to enhance the customer service performance. In a normal waiting state, the intermittent drive time interval is selected to be the time t1, so as to reduce the PHS terminal maintenance cost. When the intermittent drive time interval is selected to be the time t2 and no gas plug open command comes, even after the lapse of a prescribed time t4 (e.g., 3 days), the intermittent drive time interval is restored again to the time t1, to save power consumption of the PHS terminal.

摘要： PROBLEM TO BE SOLVED: To improve a communication success rate even at a condition that received power becomes low by controlling the maxim number of times of retransmission of data when the initial transmission from a slave machine to a master machine is failed. SOLUTION: When a carrier detection means 41a detects a start message from a master machine to a slave machine 40, a return means 41b returns a response message to the master machine. A setting operation part 48 sets whether the return means 41b transmits data that a gas meter 20 measures once by the response message or consecutively transmits them three times. Namely, a setting operation part 48 is controlled at a site in accordance with received power level from the slave machine 40 to the master machine. When received power is low, it is considered that a communication success rate is deteriorated. Thus, data are set to consecutive three times transmission when the measured value of received power, which is measured at the time of site execution, is less than a prescribed value. When received power exceeds the prescribed value, data are set so that they are transmitted only once.

摘要： PROBLEM TO BE SOLVED: To provide a radio communication system capable of simply and easily testing the propagation of radio waves. SOLUTION: When starting a radio wave propagation test, the test switch of a wireless base unit 6 is turned on (step 30). Thus, the wireless base unit 6 is turned into signal transmission inhibit mode. A wireless hand set 7 transmits a test signal to the wireless base unit 6 (step 31). When the signal is received, the wireless base unit 6 turns on an indicator for reception confirmation or sounds a buzzer but does not send the test signal to a center 2 (step 32). At the time of test end, by turning off a test switch 10 of the wireless base unit 6, the signal transmission inhibit mode is canceled.

摘要： PROBLEM TO BE SOLVED: To provide a radio communications system for efficiently executing safe measures as a fail safe function in the case of emergency report. SOLUTION: Any abnormality such as gas leakage occurs and a detector 8 transmits a detecting signal to a wireless hand set 7-1 (step 30). The wireless hand set 7-1 transmits a signal containing detection information to a wireless base unit 6 (step 31). The wireless base unit 6 transmits the detection information through a telephone line 5 to a center 2 (step 32). When any line abnormality occurs on the line with the center 2 and there is no response from the center 2 (step 33), the wireless base unit 6 transmits the break instruction of a meter 6 to a wireless hand set 7-2 connected to the meter 9 (step 34) and breaks the meter 9 (step 35).

摘要： PROBLEM TO BE SOLVED: To easily perform the exchange of a network controller which accompanies the change of a telephone line without affecting a radio equipment master unit and also to reduce the installation space for a network controller and the radio equipment master unit by forming a signaling channel between the network controller and the radio equipment when a connecting and disconnecting means connects both the devices and integrates them into one body. SOLUTION: A network controller 3 where a projecting part 1 is formed on one plane constructing the connection plane of a telephone line use terminal system is a different body from a radio equipment main unit 7 where a recessed part 5 is formed on one plane constructing a connection plane. The network controller 3 and the radio equipment master unit 7 are integrated into one body by mutually interfitting the projecting part 1 and the recessed part 5 and sliding them. And, the projecting part 1 and the recessed part 5 are respectively provided with electrodes 9 and 11 at prescribed positions so that a signaling channel can automatically be formed between the network controller 3 and the radio equipment master unit 7 at the time of integrating them into one body.
