Automated information system for the bus / railway stations AISBRS-1061

1. Purpose and scope

Automated information system for the bus stations and railway stations AISBRS-1061, hereinafter AISBRS, automatically issues voice and musical messages, recorded in its memory according to a schedule. The messages can be various: emergency situations, arrival/departure on schedule, detection of objects, location of food corners, WCs, rooms of mother and a child, etc.

AISBRS also provides the ability to transmit the voice message from the train station dispatcher by the microphone. In this case the message transmitted from the memory automatically fades.

Additionally, AISBRS can work as the primary clock of the railway clock complex (with the clock DC-0160) (function on request).

The AISBRS does not require installation and adjustment of the clock. The time is set using the satellite system GLONASS/GPS.

AISBRS has a line output and a built-in audio power amplifier which can be used for the control monitoring. Amplifying-acoustic complex is not delivered, as usually the customer’s PA audio power amplifier is used.

The device (photo 1) consists of the automated system unit, power supply unit and a microphone. The information system has a metal housing, microphone’s housing is plastic.

The automated system unit contains a built-in clock on the basis of the GLONASS/GPS receiver with an external antenna, an SD memory card, a microcontroller, an mp3 decoder, a power amplifier, a sign-synthesizing liquid crystal indicator, an outer power supply and an interface for connection with the slave clock*.

Information is recorded on a SD card of 1 Gb or higher capacity using the PC, card reader and programme.

Audio information is issued automatically according to the schedule programmed on the flash card using a PC.

The programme for transferring information on the flash card is included in the delivery set.

The microphone is switched on by pressing the button on it. When the microphone is turned on, the volume of the message being transmitted is automatically reduced (if it was being transmitted at that time).

The volume of the microphone and volume of audio files is adjusted separately programmatically using the “Volume” button and rewind buttons. The automated system unit has a separate line output for connecting an external power amplifier.

The rear panel of the device has connectors for power supply, GLONASS/GPS antenna, line output and input, acoustics, interfaces RS-485, RS-232, SPI, microphone, external message release button.
