Abstract

PURPOSE:To execute the emergency communication without fail by communicating usually from a mobile station through a receiving amplifier and a radio fixed station with a wire paging main device, but executing the automatic dialling of a private telephone set with a telephone adapter when the emergency button of the moving station is depressed. CONSTITUTION:Usually, a mobile station 1 is communicated through a receiving amplifier 2 and a radio fixed station 3 with a manned private paging main device 10. When the emergency button is depressed at the mobile station at the time of the impossibility of the communication due to some emergency state, a switch 4 is closed, a telephone adapter 5 executes the automatic dialling of a private telephone set 6 and calls out. Thus, even when the wire paging main device 10 is unmanned and the person in charge of the mobile station cannot speak, the emergency information is secured.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an abnormality notification system. Specifically, the present invention is intended to quickly and reliably report to a predetermined location in the event of an emergency, such as when a patroller working in a factory or the like becomes unable to move due to injury from mechanical equipment or sudden illness. It is related to a system that makes it possible.

[Conventional technology]

Conventional notification methods include a method in which a local telephone or wired paging terminal station is installed, and a method in which a wireless paging device is used to conduct a call between a master station and a slave station or between a slave station and the same landline.

[Problem that the invention seeks to solve]

In such a system, there are problems with the abnormality reporting system at night or on holidays, when there are few maintenance personnel, the monitoring room where the wireless fixed station is installed is unattended, and the patrollers are on duty. There is. In other words, if a patroller were to be injured by mechanical equipment or suddenly become ill while patrolling the premises, he would not be able to contact the terminal station because he would not be able to travel to the terminal station. If the person is absent, we cannot contact you. Furthermore, in wireless baging, the communication area is limited to a fixed area, so if the recipient is not within the area to which the patroller belongs, contact cannot be made.

[Means for solving problems]

The present invention solves the above-mentioned problems. For example, by using existing wireless paging, a button signal from a mobile station carried by a patroller activates a telephone adapter via a fixed wireless station, and connects to other areas. At the same time, an automatic dialing device is activated, a specific subscriber telephone is called via a telephone exchange, and a prerecorded message is sent out.

That is, the gist of the present invention is to provide a portable mobile station that transmits radio waves, a reception amplifier that receives and amplifies the radio waves transmitted from the mobile station, and transmits the amplified radio waves to a fixed wireless station; A wireless fixed station that sends a call signal to a telephone adapter, a telephone adapter that is activated by a calling signal from the wireless fixed station, sends the calling signal to a dedicated telephone, and sends a starting signal to an automatic dialing device, and a starting signal from the telephone adapter. An abnormality reporting system characterized by comprising an automatic dialing device that automatically dials a preset dial number, calls a desired telephone subscriber via an automatic telephone exchange, and sends a prerecorded message. Exists.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to drawings showing embodiments of the invention.

FIG. 1 shows a preliminary system configuration for implementing abnormality notification according to the method of the present invention.

In Fig. 1, / is a mobile station carried by a patroller and capable of transmitting radio waves, / is a receiving amplifier (booster) for receiving radio waves, and 3 is a fixed wireless station. Normal communication is /, 2.3
and 10. IO is the main device for wired paging.

This is a switch that turns on and off the connection with the abnormality reporting telephone circuit.It is ON when configuring the abnormality reporting system.
shall be. ! is a telephone adapter which is activated by a call signal from 3 and sends it to 6 and 7. Party B is a telephone exclusively for abnormality reporting, and! The built-in bell will ring with a signal from (for example, /4Hz signal). 7 is an automatic dialing device with a built-in message recording device, and! A preset dial number is automatically dialed in response to an activation signal from the telephone exchanger, and the subscriber telephone set 2 is called through the automatic telephone exchange.

Next, the operation of the system shown in FIG. 1 will be explained based on the flowchart shown in FIG.

In the event of an emergency, when a patroller presses a button on a mobile station, a carrier (radio wave) is emitted from the mobile station. The carrier is received by antennas arranged at appropriate intervals, amplified by a booster (receiving amplifier) 2, and input to a fixed station 3. 3 is activated by the carrier and sends an ON signal to the telephone adapter j via the adapter.

j is activated by the ON signal received from 3, for example /
At the same time as a 6 Hz calling signal is sent to the dedicated telephone 6, an activation signal is sent to the automatic dialing device 2. The automatic dialing device 7 is! Automatic dialing based on the activation signal from the automatic telephone exchange! and calls a predetermined subscriber telephone set 9.

The dedicated telephone set 6 and the subscriber telephone set are installed in a room where a supervisor is always present. If the dedicated telephone B answers, it becomes possible to talk to the patroller. Furthermore, when the user picks up the handset of the subscriber telephone, a prerecorded emergency message is sent from the automatic dialing device 7.

〔Effect of the invention〕

The abnormality reporting system of the present invention achieves the following effects.

■ It is possible for the pigeon roller to report an abnormality from any position in one click.

■ As long as there is a room where a supervisor is stationed at all times, emergency communications can be made even when seven people are working.

■ Even if the patroller becomes unable to speak for some reason, it is possible to report an abnormal situation by simply pressing a button.
