Title: Communication equipment
Inventor: HANAOKA SATOSHI
IPC: H04N1/32
Filed: 1989-04-11
Abstract: PURPOSE:To simplify the constitution of communication equipment by unnecessitating the connection of an integration circuit by detecting a call signal by setting a flag when receiving the signal from a line by the communication equipment, displaying the change of the signal, and judging that signal detection is performed correctly when the time-up of a timer is obtained. CONSTITUTION:The communication equipment is equipped with a signal detecting means 27, a flag means 29 to display the change of a detected signal, the timer for the judgement of the correctness/in-correctness of the signal detection, and a control part 29 to perform the processing of timer setting, etc., by reading data from the signal detection means 27. When ringer detection or the detection of a DC loop is performed by the communication equipment, each element can be detected by setting change point data at the flag, and checking the time-up of the timer. In such a way, it is possible to unnecessitate the integration circuit, which contributes to the reduction of a cost. Also, since the detection/non-detection of ringer can be judged by monitoring the time-up, detecting accuracy can be improved since no influence due to a waveform is given.

Abstract: PROBLEM TO BE SOLVED: To automatically adjust an AC voltage for ground detection, by judging the operating state of each DC power transmission system based on the switched state of a switch provided at the return pole DC line, and by adjusting the output voltage of an AC power supply. SOLUTION: When an AC power supply device 25 is connected only to a return line 6 on two-pole operation, the AC voltage of a capacitor 22 of the AC power supply device 25 is applied to the return line 6 via a capacitor 23 and a switch 54 and, furthermore, is applied to a return line 7 via a circuit breaker 13 and a switch 56. In this case, when a grounding accident occurs at F1 point of the return line 6, an AC current flowing to the grounding circuit of the return line 6 bypasses one part of the return-line 6, thus increasing the AC current, and hence detecting the occurrence of the grounding accident at the return line 6 by a grounding detection relay 16.  At this time, a return line protection device 80 controls AC power supplies 20 and 20 based on the state signal of switches 14, 15, 53, 54, 55, and 56 and the circuit breaker 13 and constantly controls current being allowed to flow to each return line regardless of an operating state.
