Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earthquake monitoring device, and more particularly to an earthquake monitoring device capable of remotely performing a complete operation test of an earthquake monitoring terminal device from a monitoring center.

[0002]

2. Description of the Related Art An earthquake monitoring terminal device equipped with a vibration sensor and an earthquake control device is installed in a building in which equipment such as an elevator is installed, and this earthquake monitoring terminal device is connected to a monitoring center via a communication line. The seismic monitoring device that has been used is conventionally used. In this earthquake monitoring device, the displacement of the pendulum of the vibration sensor due to the occurrence of an earthquake is converted into an earthquake detection signal by the earthquake monitoring terminal device and transmitted to the monitoring center via the communication line. As a result, the seismic control device operates to safely seismically control the equipment installed in the building, thereby preventing the occurrence of a secondary disaster associated with the occurrence of an earthquake. As this type of earthquake monitoring device, for example, Japanese Patent Application Laid-Open No. 58-157685 discloses an elevator seismic control operation device. When an earthquake occurs in the disclosed device, the seismic control operation device causes the elevator to seismic control. The car is switched to the driving mode, the car is guided to the evacuation floor and stopped, and at the same time, the earthquake detection signal is transmitted to the monitoring center via the communication line. Upon receiving this earthquake detection signal, the monitoring center confirms that the elevator has entered the seismic control operation state due to the occurrence of the earthquake, and takes measures for early restoration to normal operation.

By the way, in an earthquake monitoring device of a kind, when an earthquake of a specified seismic intensity or more occurs, the vibration sensor correctly detects the earthquake, and the earthquake monitoring terminal device transmits an earthquake detection signal to the monitoring center via the communication line. It is necessary for the equipment to be transmitted and the seismic control equipment be operated to safely control the equipment. For this reason, conventionally, an operation test for disturbing the normal operation of the earthquake monitoring device has been regularly performed, and the case of the device disclosed above will be described. A simulated signal equivalent to the earthquake detection signal generated by displacement is sent from the monitoring center to the seismic control operation device, and it is confirmed that the seismic control operation device operates normally with this simulated signal and the elevator can be switched to seismic control operation. is doing.

[0004]

In the operation test of the above-mentioned conventional earthquake monitoring device, when the earthquake detection signal is normally output due to the displacement of the pendulum of the vibration sensor when an earthquake occurs, the seismic control operation device operates normally. You can check if it works. However, it is impossible to confirm whether the pendulum of the vibration sensor is normally displaced when an earthquake occurs and whether the earthquake detection signal is normally output due to this displacement.

For this reason, even if an earthquake of a specified seismic intensity or more occurs, the pendulum of the vibration sensor does not undergo a predetermined displacement, so an earthquake detection signal is not output and the elevator control operation is not performed. In some cases, the pendulum of the vibration sensor caused a predetermined displacement due to vibrations below the specified seismic intensity, and the elevator control operation was performed before the earthquake occurred.

The present invention has been made in view of the current state of the operation test of the conventional earthquake monitoring device as described above, and an object thereof is to perform a comprehensive and complete operation test of the earthquake monitoring terminal device. To provide a possible earthquake monitoring device.

[0007]

The object is to provide an earthquake monitoring terminal device equipped with a vibration sensor and an earthquake control device in a building in which facility equipment is installed, and the earthquake monitoring terminal device is connected via a communication line. Connected to a monitoring center, the displacement of the pendulum of the vibration sensor due to the occurrence of an earthquake is converted into an earthquake detection signal by the earthquake monitoring terminal device and transmitted to the monitoring center,
The seismic control device, the seismic monitoring device for controlling the equipment equipment based on the seismic detection signal, a switch for switching the vibration sensor to a test mode by a command signal from the monitoring center, and the command signal And a test electric signal generating means for generating a test electric signal to be applied to the pendulum.

[0008]

With such a configuration, when conducting an operation test for confirming that the earthquake monitoring terminal device provided in the building in which the facility equipment is installed operates normally in the event of an earthquake, communication from the monitoring center is performed. A command signal is transmitted to the earthquake monitoring terminal device via the line. The command signal causes the switching device to switch the vibration sensor of the seismic monitoring terminal device to the test mode, and at the same time, the test electric signal from the test electric signal generating means is applied to the pendulum of the vibration sensor. Is displaced, and an earthquake detection test signal is output corresponding to this displacement. This seismic detection test signal is transmitted to the monitoring center via the communication line, and the monitoring center confirms that the seismic detection test signal is within the allowable range, and the seismic monitoring terminal device including the reaction operation of the vibration sensor to the earthquake. The complete operation test of is performed accurately.
