The outline of the character information display system of the present embodiment shown in FIGS. 1 and 2 is as follows. In FIG. 1, a pager 4 (16) is transmitted from a higher-level terminal 1 via a general public line 2 via a pager base station 3. ), Display information such as a message (referred to as “message”) is transmitted. Then, the message transmitted from the upper terminal 1 is received by the pager 4 (16) shown in FIG. 2, and the message is processed into display data by the data converter 15 and displayed on the display 5.

The power supply system of the character information display device shown in FIG. 2 is composed of two systems, that is, an external power supply 10 such as a commercial power supply and a storage battery 13.
And so on when the external power supply 11 is normal.
When the power supply from the external power supply 11 is cut off due to a disaster or the like, the power is supplied from the storage battery 13. That is, a power supply configuration having a buffer-up capacitor is employed.

Next, details of the function of each unit in the present embodiment are as follows. The pager 16 accommodated in the data conversion device 15 of the reception display unit is
And the like as a message signal, and outputs it to the data conversion device 15. Here, the message signal transmitted from the upper terminal 1 or the like includes one of a normal message not including emergency information and an emergency message including emergency information such as disaster information. An emergency message is transmitted with a control code added so that the transmitted message can be identified as an emergency message.

The data converter 15 is connected to the external power supply 10
Alternatively, electric power is supplied from the storage battery 13, and in principle, it is always operated, and the message signal input from the pager 16 is converted into a character signal or the like and output to the display 17. Control the mode.

The display 17 has a function of switching between a sleep mode in which the normal message is not displayed except for an emergency message and a non-sleep mode in which all messages and various displays are displayed. The switching control between the sleep mode and the non-sleep mode includes:
Control command from upper terminal 1 and external power supply 10
Is controlled by a control signal from the cubicle unit 18 based on the supply state of

In the cubicle section 18, when the AC voltage from the external power supply 10 is normally supplied, the DC stabilized power supply 11 rectifies the AC voltage to output a stabilized DC voltage, and The storage battery 13 is charged via a, and a DC voltage is supplied to the display 17 via a power supply line b. The power supply control device 12 monitors the output voltage of the DC stabilized power supply 11 and the charging voltage of the storage battery 13 to control charging, and when the external power supply 1 fails, outputs the output of the storage battery 13 to the DC stabilized power supply 11. The supply is switched. The power supply control device 12 supplies the power from the DC stabilized power supply 11 to the inverter 14, and sends the sleep mode to the data conversion device 15 depending on whether the power is supplied from the external supply power supply 10 or the storage battery 13. Alternatively, a control signal for controlling to either the non-sleep mode is output via the signal line c. The inverter 14 converts the DC power supplied from the power supply control device 12 into power and supplies the DC power to the data conversion device 15.

When the external power supply 10 is cut off in an emergency such as a disaster and the operation is switched to the operation of the storage battery 13, the power flow is as follows: the storage battery 13 → the stabilized DC power supply 11 → the display 1
7, and the storage battery 13 → the stabilized DC power supply 11 → the power supply control device 12 → the inverter 14 → the data conversion device 15, and the character information display system is operated by the power supply of the backup storage battery. When the pager 16 is installed and connected to the data converter 15, it receives power from the data converter 18.

As can be understood from the above, when the external power supply 10 is cut off and normal power supply is not performed, the storage battery 13 is switched to supply power.
The stabilized DC power supply 11 outputs a stabilized DC voltage from the storage battery 13 to drive the display 17, and the power supply control device 12 supplies power to the data conversion device 15 via the inverter 14. Reference numeral 12 outputs a control signal to the data converter 15 to set the display 17 in the sleep mode. In addition, the upper terminal 1 can control the display 17 to a non-sleep mode by a control command in a normal state, and to the sleep mode at night or when the display 17 is not used.

In the present embodiment, the upper terminal 1 transmits a control command relating to display control of the character information display device and switching of the power supply to be used, and switches the power supply to be used to the external power supply 11.
Or the storage battery 13 can be switched, and the display operation can be switched to either the sleep mode or the non-sleep mode, and it depends on whether the transmission message is a normal message or an emergency message. Switching can be performed to perform a display operation.

(Description of Operation) Next, the operation of the character information display system of this embodiment shown in FIG. 2 will be described in detail.

The transmitted emergency information is displayed at any time, and the transmission of information such as a disaster and the response to the disaster can be performed quickly and smoothly.

In order to release the sleep mode as required, the host terminal 1 transmits a sleep mode OFF control command for releasing the sleep mode. The data conversion device 15 that has received the control command displays the display 17.
Wake up from sleep. The display 17 whose sleep has been released can be operated normally by the storage battery 13. In this case, the display 17 can be configured to display a message or the like received up to that point.

In the above-described embodiment, the control is performed so that the sleep mode is switched to the sleep mode when the external power supply 10 is switched to the storage battery 13 in the event of a disaster. By transmitting a sleep mode ON control command for switching to the mode to the pager 16, the power supply source can be switched from the external power supply to the storage battery 13, and the character information display system can be switched to an emergency operation. is there. Further, as a display form in an emergency, it is possible to arbitrarily suppress the brightness or display the sound by voice display or the like in addition to the visible display. As the external power supply, a solar cell power supply can be used instead of the commercial power supply.

Further, the field of application of the present invention includes a display for transmitting and displaying disaster prevention emergency information used by a public organization, an emergency display in a vehicle (for example, in an emergency state or an emergency stop in a vehicle).
In addition, an indicator or the like at the time of an incident or accident in a factory can be considered.
