Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an alarm device that uses a voice synthesis IC circuit and can notify maintenance personnel more accurately and quickly.

Conventional alarm circuits that use a single sound such as a bell, buzzer, or chime have the disadvantage that the location of the failure is unknown, so it takes time to discover the location of the failure, which delays initial recovery from failure.

SUMMARY OF THE INVENTION An object of the present invention is to provide a remote monitoring and control device with an alarm device that has two different alarm means for detecting that there is no operation for a certain period of time and issuing a final notification via a bell or a buzzer.

Conventionally, as shown in FIG. 1, alarms were limited to alarms such as bell 3, buzzer 4, chime, etc., so it was necessary to consolidate them into about 3m'1 category depending on the status and importance of failure detection 1. In addition, it was difficult to adjust the volume, and there was no alarm device suitable for the environment of the operator's cabin, and there was a growing demand for a new alarm device from the equipment operation JIL'. In the past, there were no problems with round-up and loud alarms, which were monitored by operators 24 hours a day. However, in recent years, automated systems that have introduced remote monitoring and control devices are increasingly monitoring newspapers, such as by taking a nap in a rest room at night, rather than constantly monitoring them.

In this way, conventional alarm circuits cannot respond to changes in the operating system, and new demands from operators are being met, such as being able to freely adjust the volume, providing as much detailed information as possible about the location of the failure, and providing initial warnings. The town's new need for redundant backup alarms in case of no operation has become stronger.

Hereinafter, one embodiment of the present invention will be explained using diagram IK2. The contents of the failure detection unit 1 are divided into small units such as 11 to 13 depending on the part of failure detection. A good signal detected as a failure within each minimum unit unit is inputted to the voice synthesis alarm circuit 14, which synthesizes a preset voice. For example, if the fault detected at 11 fault detection points is a "grounding fault", the voice will say "grounding fault has occurred", "grounding fault has occurred", etc.
... etc. will be issued. Audio volume 15
Depending on the situation in the control room, the volume can be set to f14!1, and is output from the speaker 17 via the amplifier 16. Since it is possible to create an audio alarm for many types of alarms depending on the nature of the failure, the alarm can be set according to the location of the failure.

Also, if the operator does not notice due to the voice warning, the bell 3 and buzzer 4 in the latter stage can be used to issue the warning at a louder volume, thereby creating a multiple effect.

FIG. 3 shows a detailed circuit diagram of the voice synthesis alarm circuit 14 shown in FIG.

In the figure, 21 is a circuit that synthesizes audio corresponding to the input of 11, 22.23 is a circuit that synthesizes audio corresponding to 12°13, and 24 is a circuit that ORs the outputs of 21°22.23. , 25 shows an AND circuit of the output of 24 and 31 human power, and 26.27 also shows an AND circuit. 28 is 1
1.12.13 signal OR circuit, 29 is a timer circuit that determines the time of the first stage and the second stage, 30 is a circuit that determines the bell and buzzer of the second stage, and 31 is a time signal that releases the synthesized voice of the first stage from the timer circuit. Reference numeral 32 designates a time signal for emitting a subsequent bell or buzzer, 33 a signal given to a bell or buzzer determination circuit, 34 a bell drive signal, and 35 a buzzer drive signal. The signal from 11 that detects a failure generates a sound in the voice synthesis circuit 21, passes through the OR and AND circuits 24 and 25, and generates an audio alarm within the first stage release time of 31 until the alarm is stopped. do.

If there is no alarm stop operation within the first stage release time of 31, 32
The latter stage is designed to issue a bell and buzzer alarm depending on the release time.The first stage uses a soft sound to transmit detailed failure information to the failure location, and the second stage as a backup provides a strong warning sound from the bell and buzzer to give final precautions. prompting users to perform failure recovery operations more quickly.

Note that 2 in the figure is a bell/buzzer discrimination circuit.

According to the present invention, the first stage has the advantage that the environment in the control room is softer and the location of the failure can be identified more quickly, and the final warning can be given using the bell or buzzer in the second stage, allowing for speedy response to failure recovery.
