| PROBLEM TO BE SOLVED: To provide an oscillation detector applied to a radio repeater capable of automatically detecting whether or not the radio repeater is oscillated. SOLUTION: In the case of performing communication by TDMA(time division multiplex communication system), the level of DC components included in the output signals of this radio repeater is judged in a judgement circuit 16 and supplied to a monitoring circuit 17. Also, the level of AC components included in the output signals is judged in the judgement circuit 15 and supplied to the monitoring circuit 17. In the TDMA, a frame to which plural channels are allocated is turned to a communication unit. In the meantime, the input levels of the respective channels are normally different. Thus, normally, the AC components are included in the output signals. On the other hand, when the radio repeater is oscillated, since the level of the output signals is fixed at all times, the AC components are not included. In the monitoring circuit 17, when a DC level reaches a stipulated level equivalent to an upper limit and an AC level is less than a reference level, it is judged that the radio repeater is oscillated. | ||||||

| PURPOSE:To prevent previously the breakdown of a battery within a solar battery power supply device by providing a confirmation signal send-back function which works in a stop control mode to a repeater station device and therefore attaining an assured repeating stop action. CONSTITUTION:A receiver 5, a transmitter 6, a control signal check circuit 10, a stop signal check circuit 9, a logical circuit 14, a power supply control circuit 13, etc. are provided to a repeater station device which relays the control signal given from a control station device of a remote monitor controller to a device of a station to be controlled. In addition, a power supply state confirming circuit 17 containing a timer circuit 18, an oscillator 19, a switch SW6, etc. is added to the repeater station device. When a stop signal is received by the receiver 5, a power supply cut-off command is delivered to the circuit 17 from the circuit 13. The oscillator 19 is started when the time set to the circuit 18 elapses according to said power supply cut-off command. Thus the power supply to a modulator 7 and the transmitter 6 is cut off, and therefore the transmission of a tone signal to a device of a control station is stopped. When a start signal is received, switches SW3, 4 and 6 are started by the circuit 13. Then the tone signal given from the circuit 17 is transferred to the device of the control station. | ||||||

| PURPOSE:To reduce the disturbance to a receiving image and to prevent malfunction of a monitoring signal, by applying phase-modulation to a video or a sound signal without intermitting the video signal, and superimposing the monitor signal. CONSTITUTION:The equalization is applied to a comparator 14 so as to make the ratio of the level of the video and sound signals 4:1. Then, a phase modulator is inserted to a main line of a video signal system or that of a sound signal system of a VA equalizer. A phase modulator 16 is inserted to an output of the video signal, and the monitoring signal comparising an on/off signal in a low frequency or a pulse signal is superimposed on a broadcast wave by applying the phase modulation on the video signal in response to the monitoring signal. Thus, the monitoring signal is detected in the monitoring station by extracting the phase modulation component in the video signal in a receiving signal. | ||||||

| PURPOSE:To use a unit of radio transmitter and receiver each at a repeater station and then use a wave for the radio frequency, by adding a delay element to the repeater of the repeater station. CONSTITUTION:The control signal 211 supplied from the monitor controlling device 1 of the control station A is modulated to the radio frequency by the radio transmitter 21 and then demodulated by the radio receiver 31 of the repeater station C to be turned into the signal 312'. The signal 312' is delayed by the delay element 7 to be turned into the transmission signal 212', modulated again to the radio frequency by the radio transmitter 21 to be transmitted to the station B to be controlled, and demodulated by the receiver 31 to be turned into the reception signal 213'. The signal 213' is transmitted to the monitor controlling device 5. The state displaying signal 311 sent from the device 5 is modulated by the transmitter 21 and then transmitted to the station C. The signal 311 is then demodulated by the receiver 31, delayed by the element 7, modulated by the transmitter 21 to be transmitted to the station A, and demodulated by the receiver 31 to be turned into the reception signal 313'. The signal 313' is then transmitted to the device 1. | ||||||

| PURPOSE:To make easy the detection of signal at the lower rank station, by making easy for the insertion of pilot signal at the relay station, through the phase modulation with the second pilot signal having slight frequency difference with the radio pilot frequency for the signal inserted at the direct relay station. CONSTITUTION:The output of the transmitter T is made from the antenna A1 modulated with the radio pilot signal P1. The reception signal from the antenna A2 is added with the phase modulation with the second pilot signal P2 fed to the phase modulator PM, amplified at the amplifier AMP and outputted from the antenna Ao. The electromagnetic waves are inputted from the antenna A4 of the reception station, demodulated at the receiver R, and the signals P1, P2 in the demodulation signal passes through the same BPF, detected with the detector D1 with the envelope detection, and outputted from the output terminal 1. When the level of the signal P2 is made smaller than the signal P1, the disappearence of the signal P1 changes the output from the terminal 1 and the presence of the signal P1 can be detected. Further, the output of the detector D1 is detected with the detector D2 of LPF, allowing to detect the beat of the signals P1 and P2. | ||||||

| PROBLEM TO BE SOLVED: To avoid duplication in the transmission system by allowing the transmission system management equipment to decide an identification number with respect to all transmission devices, sending the number to each transmission device and allowing all the transmission devices to set internally the identification number provided to each equipment. SOLUTION: A transmission system management equipment 30 sends an 'dajacent station information request' to all transmission devices for a prescribed period in multiple address. Each transmission device receiving the multiple access transmission of the 'adjacent station information request' provides an 'device manufacturer's name + device name + device manufacture number' specific to its own device and 'adjacent station information' as to an adjacent station to an 'adjacent station information request reception confirmation' and replies to the equipment 30. For example, a repeater 22 receiving the multiple address transmission of the 'adjacent station information request' adds the 'equipment manufacture's name + device name + device manufacture number' specific to its own device 22 and the 'device manufacture's name + device name + device manufacture number' of adjacent repeaters 21, 23 to the 'adjacent station information request reception confirmation' to reply to the equipment 30. | ||||||

| 58 | Automatic return tester | JP7862983 | 1983-05-04 | JPS59204333A | 1984-11-19 | TERUI KOUKI |
| PURPOSE:To suppress the time of circuit disconnection as much as possible and to improve the reliability of a circuit by conducting a return test only when an abnormal state continues for a specific time after abnormality of a receiver is detected. CONSTITUTION:An automatic return tester 2 is set normally in a stand-by state. When the receiver 1 becomes abnromal and its detection signal is applied to a logical circuit 3, the circuit 3 drives an oscillator 4 when the detection signal is in the same state continuously for longer than the specific time. A shifter 6 generates a signal of the same frequency with a receiving signal by a signal from the side of a transmitter 5 and a signal from the oscillator 4 and sends out the signal to the receiver 1 through a BPF7 and a coupler 8. When this signal is outputted to the output terminal of the receiver 1, the circuit 3 decides that the receiver 1 is normal, and when no, it is decided that the receiver 1 is faulty. The circuit 3 does not conduct the return test when the abnromality detection signal is ceased within the specific time. | ||||||

| PURPOSE:To reduce the disturbance to a receiving image and to prevent erroneous operation of a monitoring signal, by applying amplitude modulation to sound FM signal without intermitting a video signal for superimposing the monitoring signal. CONSTITUTION:A comparator 14 compares the output level of amplifiers 13, 14 to attain equalization so that the ratio of the level of video and sound signals is 4:1. A switch 16 is inserted to a main line of a wound signal system in a VA equalizer 10. The switch 16 consists of a diode switch and the like and inserted to a sound signal output, closed normally and when a monitoring signal input exists, the switch 16 is controlled with the input to intermit the sound signal output amplitude-limited at the amplifier 13 or to decrease the output level so as to superimpose the monitoring signal on a broadcast wave by applying amplitude modulation to sound signal output. Thus, the monitoring signal is detected by monitoring the sound signal level in a receiving signal in the monitoring station. | ||||||
| 60 | Automatic folding tester | JP7094582 | 1982-04-27 | JPS58187038A | 1983-11-01 | TERUI KOUKI |
| PURPOSE:To minimize the frequency of line interruption, by stopping the folding test for a prescribed time, after a failure in a reception signal is detected and the folding test is executed once. CONSTITUTION:When a receiver 1 is failed and its detection signal is applied to a logical circuit 7, an oscillator 3 is driven and a shifter 5 generates the same frequency as that of the reception signal with a transmission signal from a transmitter 4 and a signal of the oscillator 3. The generated signal is transmitted to the receiver 1 via a filter 6 and a coupler 8. When this signal is outputted to an output terminal of the receiver 1, the circuit 7 discriminates that the receiver 1 is normal, and when the signal is not outputted, the circuit 7 discriminates it as in failure. The circuit 7 stops the folding test for a prescribed time when the receiver 1 is normal. If fading takes place frequently in a short time, since the failure is detected because of the 1st fading, the folding test is stopped for a prescribed time and no folding test is exercised even if the fading takes place during the time. | ||||||
