Then, the installation and operation principle when installing the multi-purpose radio alarm device using a radio transceiver of the present invention in a railway vehicle will be described.

First, the transmitter is installed at a certain distance ahead of the point where the alarm is required. At this time, the installation distance is set in consideration of the time required for the engineer's action.

The transmitter is divided into ascending and descending when the number is set, and includes data for distinguishing the up / down line from the outgoing radio signal.

The time required for one transmission is about 100m Sec (0.1 sec), and this signal consists of 2 words of equipment identification code, 1 word of up and down identification code, and 1 word of alarm number after the initial stabilization period.

One receiver is installed in each cab, and the switch is divided up and down, and when the power is supplied from the THR, only the receiver in the cab where the engineer works is operated.

At this time, the receiver identifies the up / down separation signal included in the radio signal and operates only on the signal coming from the corresponding transmitter.

Therefore, it prevents the case where it is installed adjacent to both up / down tracks, and operates in a position other than an alarm point even if a reception range is far.

If the up / down position is changed, the up / down division of the transmitter or receiver should be changed.

The transmitter and receiver do not need to be operated separately after installation. However, after the alarm is issued, the engineer can stop the alarm sound and the alarm by using the switch on the receiver.
