Therefore, a safe refuge direction is instantly displayed regardless of the judgment and action of a disaster manager and refuge guide can be smoothly performed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applied to a disaster prevention system. The present invention relates to an emergency information display device installed in hotenope inns, public facilities, and the like.

[Summary] The present invention provides an emergency guidance display device that displays guidance when an abnormality occurs, and includes means for identifying an electric signal from an abnormality detection sensor to determine and display an evacuation direction. This makes it possible to clearly indicate the

[Conventional technology]

Conventionally, in order to notify of abnormalities at hotenope inns, public facilities, etc., a sensor detects smoke or temperature, takes the output of this sensor, converts it into a predetermined electrical signal, and sends it to a terminal device.
A device is used in which a terminal device operates an alarm device to sound a buzzer or turn on an emergency light to notify the user.

In addition, the emergency lights on the central control panel that are lit in each building or room installed at the front desk or in the central control room will notify you as to which room the abnormality has occurred in. Evacuation guidance is in progress.

One way to connect each sensor and terminal device of such a disaster prevention notification system to each emergency light of a central control panel is to connect two communication lines into branches and identify each building or each room using digital codes. Although it exists, it is only used to identify the position and not to indicate the evacuation direction.

[Problem that the invention seeks to solve]

With the conventional disaster prevention reporting system described above, it is possible to know when an abnormality has occurred by sounding a buzzer or turning on emergency lights, but it is difficult to immediately determine where the abnormality has occurred and in what direction to evacuate. Therefore, evacuation actions must be taken after the disaster prevention manager broadcasts the message or the staff who receives the instructions guides the person.

In this way, conventional methods require appropriate judgment and action by the disaster prevention manager, but in actual situations, the disaster prevention manager himself or herself may not be able to take appropriate action, and it may be difficult to do so due to lack of time. In emergency situations where disaster prevention managers have made appropriate judgments and actions, it may be difficult to fully implement their instructions. Therefore, it is desirable that evacuation guidance in a safe direction be performed immediately and automatically, regardless of the judgment or actions of the disaster prevention manager.

In addition, in terms of equipment, the main device, relay device, and terminal device are manufactured to different specifications, and the lines between these devices and the central control room are individually wired, resulting in high costs.

The present invention eliminates these problems and provides an emergency guide that immediately indicates the evacuation direction in the event of an abnormality, allows equipment to be manufactured at low cost, and reduces wiring costs. The purpose is to provide a display device.

[Means for solving problems]

The first invention includes a sensor that detects an abnormality, a terminal device that takes in the sensor output, converts it into a predetermined electrical signal, and sends it to a line, and a display device that is connected to the terminal device and displays the evacuation direction. In the emergency information display device, the line is a two-line communication line, and the terminal device includes a means for adding an identification code unique to the terminal device to an electric signal transmitted to the line and transmitting the electric signal, and a means for transmitting an electric signal unique to the terminal device, and a means for transmitting the electrical signal to the electric signal transmitted to the line. and means for identifying the electrical signal and determining the retreat direction.

In a second invention, in addition to the above, the - part of the terminal device is a relay device comprising means for mutually relaying and connecting signals between the two-wire communication line and another two-wire communication line. , a main device connected to the two-wire communication line or the two-wire communication line on the side, the main device comprising means for transmitting a reset signal to the connected two-wire communication line, and the main device includes means for transmitting a reset signal to the connected two-wire communication line, The device and the relay device are characterized in that they include means for receiving and identifying this reset signal and means for resetting the operating state to the initial state in accordance with the output of this means.

The terminal device, the relay device, and the main device are devices with the same specifications, and each includes a program control means and a multi-digit digital switch, and the program control means controls the terminal device, the relay device, and the main device. It is possible to include any control logic of the main device in advance and to include means for selecting and executing any of the control logics according to the code set in the digital switch.

[Effect]

When a sensor connected to a terminal device detects an abnormality due to smoke or temperature rise, the terminal device takes in this sensor output, converts it into a predetermined electrical signal, adds a unique identification code, and sends it to the main device and each device via a line. It is sent to relay devices installed in the building and on each floor.

The relay devices on each building and each floor relay this signal to the main device or to multiple terminal devices under its control. is identified using pre-stored data, a safe evacuation direction corresponding to the abnormal location is determined, and each is displayed on the display device. Furthermore, the main device can receive this abnormality occurrence information signal and display the room number where the abnormality has occurred on a display panel in a central control room or the like.

When the notification process is completed and the reset button is pressed, a reset signal is sent to each terminal device via the relay device, and each relay device and each terminal device resets the display device using this signal. Further, when an abnormality signal is received from the existing system, the signal can be sent to each terminal device via each relay device, and the evacuation direction can be similarly displayed.

If the terminal device, relay device, and main device have the same specifications, they can be used as either device by the code assigned by the digital switch.
