India - Mumbai Metro Line 3

Currently, India's Mumbai Metro Line 3 is under full construction. This 33.5-kilometer-long line will be Mumbai's first underground metro line, featuring 27 underground stations and 1 ground-level station. Its successful completion will connect other metro lines, monorail, suburban railways, intercity railways, and Mumbai Airport, among others, significantly reducing traffic congestion on Mumbai's urban roads and alleviating the overload on other lines. Traditional manual ticketing cannot meet today's massive and efficient travel demands, therefore, the need for Automatic Fare Collection (AFC) systems is particularly urgent and important.

Automatic Fare Collection (AFC) System

The Automatic Fare Collection (AFC) system primarily consists of two major parts: the application management system (clearing center system, central computer system, station computer system) and fare collection equipment (automatic ticket vending machines, entry/exit gates, etc.). It is an automated network system based on various high-end technologies such as computer technology, internet technology, and mechatronics, utilizing centralized computer control for automatic ticketing, automatic fare inspection, and automatic fare collection and statistics. This system is characterized by intelligence, high efficiency, and safety and reliability. It is widely used in urban rail transit both domestically and internationally, significantly improving travel efficiency.

Automatic Fare Gate

The Automatic Fare Gate (AFG, or simply 'Gate') is a crucial component of the automatic fare collection system. It is installed at the boundary between the non-paid and paid areas of a station, serving as the verification gate for passengers entering and exiting the metro station. The entry/exit gates automatically and accurately calculate passengers' travel fares, while effectively managing the flow of passengers.

Application Requirements

The client approached us, hoping we could provide stable and efficient fanless industrial computers for their automatic fare gates. Each automatic fare gate requires a dedicated industrial computer. Based on the operating principles and characteristics of automatic fare gates, the following requirements were put forth:

Performance capable of meeting basic control, analysis, and data transmission needs.
Multiple I/O interfaces to connect all access control modules and their sub-components, with convenient wiring.
Compact overall design, easy to disassemble and assemble.
Excellent stability, reliability, and maintainability.

Product Solution

The client ultimately chose a solution that provides robust and stable support for their application. It utilizes an Intel J1900 CPU, a quad-core, quad-thread processor, capable of basic control, data analysis, and transmission. Rich I/O interfaces, including 6*COM ports, meet the connection requirements for devices such as automatic ticket dispensers, contactless IC card readers, gates, and alarms. Multiple network ports and USB interfaces enable communication with system terminals, and all interfaces are distributed on the front and rear panels, facilitating convenient device wiring. The model is small and compact, adopting a cable-free direct-docking architecture, making it robust and stable, capable of long-term stable operation, 24/7 uninterrupted. The isolated top-and-bottom heat dissipation design allows it to operate within a temperature range of -20°C to 65°C, better adapting to harsh working environments.
