Information display panel of the stop shelter IDPSS-0743

Purpose.

The display panel of the stop shelter (photo 1) is intended to display information about the estimated arrival time of the transport vehicles to the bus stop. The table is intended for the passengers, standing at the stop waiting for the transport vehicle arrival.

Principle of operation and brief characteristics

The display panel has 3 and ⅓ information LED lines.

The upper ⅓ line shows alternating information: date / time / temperature.

The three lines below show information about the arrival of a transport vehicle at the stop. Each line contains the following information:

- route No. (displayed statically);

- name of the final stop (displayed dynamically by the scrolling text or statically depending on the number of characters in the name);

- estimated time of arrival / how much time (in minutes) is left until arrival (displayed statically).

Furthermore, the lower line can be used for displaying service, advertising information.

If the number of vehicles arriving at the bus stop is more than three, the information regarding them is displayed alternating (scrolling) with an interval of 10 – 15 sec.

The display panel can be single-sided or double-sided (1/2) with red or yellow LEDs with the in-built or outer power supply unit with the accumulator (see supplement 1).

The display panel can be installed either of the roof of the bus stop shelter or on the pole standing near the stop.

The panel is fixed to the pole with special brackets.

Principle of work Purpose and scope Contents of delivery Basic technical characteristics Basic functions

The display panels are one of the components of the Automated Dispatch Management System of the urban public transport (please refer to pic. 1).

The principle of the system is as follows:

Transport vehicles, equipped with the satellite subscriber terminals, transmit their location coordinates in real time to the Automated Management System server. The Automated Management System server processes the data received from the transport vehicle, determines the estimated arrival time of the vehicle at each stop and transfers data to the display panel server. The display panel server transmits the data received from the Automated Management System server to the display panels upon requests from them with a period of about 1 min. The received data is displayed in the lines of the panel.

The panel communicates with the server via the GSM/GPRS cellular channel.

Pic. 1. Functional scheme of the IDPSS Automated Management System

The display panel has an anti-vandal design: the metal case and the glass made form the monolithic shockproof polycarbonate.

If the voltage on the ~220 V electrical network may periodically be absent, it is recommended to power the panel from the uninterruptible power supply.

IDPSS (photo 1, pic. 2) is made in the form of the information field consisting of red LEDs. Information, transmitted to the display panel, is displayed on four lines from two sides. Change of information in each line is possible both in the form of instant replacement and in the form of the scrolling line.

The upper line periodically displays current date / time / air temperature.

The route information is displayed on the 2^nd and 3^rd lines. The scrolling line for each vehicle includes information about the route number, time until arrival at the stop (in minutes).

The 4^th line is intended for displaying various text information: information from the transport company, information about emergency situations, advertisements.

Note: if the vehicles passing through the stop are not equipped with the navigation equipment, the arrival time of these vehicles is not automatically displayed.

The number of the displayed routes is not limited. If there are more than 2 routes at the stop, the routes are displayed cyclically with the given period depending on the number of routes passing through the stop.

IDPSS is made in the metal protective case. Both sides of IDPSS are protected by the impact resistant plastic.

An SD card and a SIM card are located on the bottom panel of the display under the cover.

IDPSS is mounted on the structural elements of the stop shelter. An electric cable with the voltage 220 V designed for power consumption up to 200 W is supplied to the display panel.

Operating mode of the IDPSS-0743 – around-the-clock.
