摘要： PURPOSE: To continue an operation for a long time by battery driving by making the transmission timing of each terminal coincide with the reception timing and supplying a power source to a transmission/reception means intermittently by providing a remote control means and a periodical transmission means. CONSTITUTION: This system is equipped with a center device 1, a public telephone network 2, housing facility equipment 16 consisting of an informing means and a control means, a transmission/reception antenna 18 and the periodical transmission means 23(constituted of a clock means 19, a response designation means 21 and a state monitoring means 22). Also, a first terminal 101 is equipped with a gas leakage sensor 26, a clock means 28, a clock correction means 29, an identifying response means 30 and an unidentifying response means 31. Also, a second terminal 102 is equipped with a flow rate sensor 36, a clock means 38, an identifying means 40 and an unidentifying means 41. In such a case, since a transmitting/receiving operation is performed between plural sensor means 26, 36 and the equipment 16 at a certain synchronized timing, bidirectional communication can be performed, and also, not only the plural sensor means but the housing facility equipment like the informing means can be battery-driven.

摘要： PURPOSE:To obtain the communication system with high reliability by using a clock signal for both a PLL and a microcomputer by a clock signal from one oscillator so as to reduce the cost. CONSTITUTION:When a frequency oscillated by an oscillation means 1 is not a frequency required for a control means 4 or a PLL means 3, the frequency is divided or multiplied by using a frequency divider function in the inside of the means 4 or 3. The means 4 sets a power supply for the means 3 and selects a clock signal for a microcomputer from a sub clock signal into a main clock signal for succeeding transmission processing before and after the PLL is locked. It is general that much time takes to obtain normal oscillation of the main clock signal. Since the clock signal for the means 3, 4 is used in common, the presence of the oscillation of the main clock signal is confirmed by the clock signal of the means 3. Since the clock time of the means 3 is confirmed, the timing when the sub clock signal is switched into the main clock signal is checked.

摘要： PURPOSE:To obtain a flow measuring device by providing a reception state monitor means monitoring a reception state and outputting the reception state to the measuring device so as to collect integration data with high reliability. CONSTITUTION:A radio wave radiating from a gas flow measuring device is received by a reception means 13 via an antenna 14 of a data collecting side. The reception means 13 provides an output of a binary code to a control means 12. Then a reception signal amplified by the reception means 13 is inputted to a detection means 17 forming a reception state monitor means 18. The detection means 17 converts the signal into a binary code in response to a reception level. A notice means 19 stores both the binary code representing the reception state sent from the gas flow measurement equipment and demodulated by the reception means 13 and the binary code in response to the level of the reception signal detected by the detection means 17. When the level of the binary code representing the stored reception level is less than a predetermined reference level, it is informed externally to inform a bad reception state.

摘要： PURPOSE:To provide the receiver for receiving a transmitted signal, to which Manchester encoding is performed, without degrading the S/N. CONSTITUTION:Since the band of a band limit filter 10 is set double as high as NRZ signal reception at the receiver for receiving the Manchester encoded signal, the S/N is degraded for 3dB rather than the time of NRZ signal reception but a signal, which S/N is improved for 3dB rather than a source signal, is provided by inputting a signal passed through the filter 10 to a data arithmetic means 11, inverting that signal at a signal inverting means 12, delaying it for one bit at a signal delay means 13 and adding the source signal and the output of the signal delay means 13 at a signal adding means 14. By detecting data from this signal, the degradation of the S/N for 3dB at the filter 10 is canceled and as a result, the degradation of the S/N is turned to 0dB.

摘要： PURPOSE:To shorten a lock-up time as much as possible and to perform FSK modulation to the oscillation frequency of a VCO directly with code strings by varying the signal transmission characteristics of an LPF at the time of lock-up and transmission. CONSTITUTION:For a reception operation, the radio waves of 429.75MHz, inputted to an antenna 1 are amplified through a transmission/reception switching means 2 in a high-frequency amplifier means 3 and then converted to 450kHz of an intermediate frequency in a frequency conversion means 4. Then, FSK demodulation is performed by a detection means 6. The signals of the VCO 8 are 34344-frequency-divided by a frequency divider means 9 and the reference signals of 12.5kHz are outputted at a reference frequency oscillation means 10. The phases of the 12.5kHz reference signals and the 34344-frequency-divided signals from the means 9 are compared and a phase difference is outputted in a phase comparator means 11 and the high-frequency components of the 12.5kHz signals are removed in the LPF 15. Then, the VCO 8 is controlled so as to make the phase difference '0' and the oscillation frequency is turned to 12.5kHzX34344=429.3MHz. The frequency dividing number 34344 of the frequency divider means 9 is set by the signals from a control means 16.

摘要： PURPOSE:To receive a signal of large frequency shift or a signal of high code change speed to reproduce the code string of transmission data without error. CONSTITUTION:A phase difference detecting means 11 which detects the phase difference between signals from first and second mixing means 3 and 8 and a frequency correcting means 15 which detects the difference between a carrier signal frequency to be received and the signal frequency from an oscillating means 6 and controls the oscillation frequency of the oscillating means 6 in the frequency error eliminating direction are provided. A multiplying means 16 is provided which multiplies the signal by the signal of a pulse signal generating means 18 which generates a pulse signal from the signal of the phase difference detecting means 11 synchronously with a bit synchronizing signal. Thus, an angular frequency error (x) between the carrier frequency to be received and the oscillation frequency of the oscillating means 6 is corrected, and the code change speed is reduced to accurately reproduce a code string p(t).

摘要： PURPOSE:To register and confirm an identification code on a transmission side without moving or coming into contact with the reception side of a commu nication equipment. CONSTITUTION:A register signal composed of a transmission side code to be newly registered and a reception side code designating a reception party to register the transmission side code is transmitted from a transmitter 1. When the received reception side code is coincident with the identification code of a receiver 2 itself, the receiver 2 receiving the register signal registers the transmission side code on a transmission side code registration part 3b and transmits a response signal to the transmitter 1. The transmitter 1 receives the response signal and confirms the registration.

摘要： PURPOSE:To reduce the influence of radio interference by normally minimizing and transmitting a transmission output, and increasing and retransmitting the transmission output only in case of a failure in transmission. CONSTITUTION:When a wireless remote controller 5 is operated, the operation contents are immediately converted into operation information, whose packet signal is generated by adding transmission control information, etc., and transmitted from a remote control transmitter 7 to a hot water supplier 1. The transmission output of the remote control transmission part 7 is switched between high and low stages; the transmission output is normally made to be low and transmitted, but the same is increased and retransmitted if there is a failure in the transmission for some reason. Namely, a retransmission control part 12 stores the packet signal transmitted from the remote transmission part 7 to the hot water supplier 1, and when an answer signal to it is not received by a remote control reception part 8 within a certain period of time, the packet signal containing the same operation contents is transmitted again to the remote control transmission part 7 and an instruction for increasing the transmission output of the remote control transmission is outputted.
