Metro, light rail, urban rail, and fast rail are collectively referred to as rail transit. How to use advanced electronic means to improve the efficiency of rail transit systems, obtain the benefits of urban traffic passenger flow information services and system operations, and guarantee the return of investors are becoming the focus of attention for rail transit system operators and investors. 2.1 Automatic ticketing system The automatic ticketing system is mainly composed of a central system, a station system, terminal equipment and a ticket. The terminal equipment includes on-site equipment such as exit/inspection ticket gates, automatic ticket machines, station ticketing systems, automatic recharge machines, and automatic ticket machines. Tickets include one-way tickets, stored-value tickets, and special tickets. Automatic ticketing system (afc) is an automated system based on network, calculator, automation control, communication, and completing the entire process of railway network ticketing, ticket checking, billing, charging, statistics, and management. Allows passengers to enjoy automatic ticket purchase, automatic ticket checking, automatic recharge, and automatic inquiry when traveling on the subway. The system block diagram is shown in Figure 1. Figure 1 Auto ticketing system block diagram 2.2 Automatic ticketing terminal The terminal of automatic ticket counting and time-based charging mode adopts a fully-closed operation mode. The non-contact IC card is used as the ticket medium. The computer network system for automatic fare collection with high security, reliability and confidentiality is used to complete the operation of the subway/light rail system. Ticketing, ticketing, billing, billing, statistics, etc. ticketing operation of the entire process, multi-task automation management. Based on the arbor company arpex-1600 computer automatic ticket machine shown in Figure 2. Figure 2 arpex-1600 automatic ticket vending machine 2.3 arpex-1600 host (1) The apex-1600 control calculator in the automatic ticketing system of this case is applied to the automatic metering and ticketing system (AFC) of the Panyi Metro. The arbor-developed integrated fanless design arpex-1600 industrial computer, with a high reliability of the fanless design to ensure long-term operation of the system, compact and ultra-thin dust design, ensure the stability of the system and easy to install a variety of strict Harsh use environment. (2) arpex-1600 control calculator uses exclusive patented message go! The function can directly monitor the operating status of each function in the arpex-1600 directly from the arpex-1600 on-board text display. No additional external display is required to improve the convenience of the back-end maintenance, as shown in Figure 3. image 3 (3) arpex-1600 ticket control computer-rich 4 rs232 serial port (of which 2 support rs422/rs485) and 2 usb port, can be connected to the surrounding, such as banknote recognizer, coin recognizer, coin changer , led billboards, and touch screens, while arpex-1600 built-in exclusive sdr (smart data recovery) technology to ensure that important data is not lost, and with the data back to the function. 3.1 Subway Streaming Media The urban subway project includes a variety of construction projects and complex processes. In addition to ensuring the safe and high-speed normal operation of subway vehicles, it also requires the improvement and follow-up of related supporting facilities. In this way, we can improve the entire subway traffic network. The media playing system is one of the projects in this area. It not only needs the wireless alarm and alarm information of the emergency broadcast system command department, but also broadcasts general subway arrival videos. It can be said that the subway streaming media carries the entire activities of the humanization of the subway. Compared with subway metrology and control systems, they can adapt to the special environment of the subway for a long time and they must also shoulder the heavy workload of video processing. This means that the machine itself needs a higher performance CPU and overall performance. 3.2 Fanless IPC Development After the experiment of the engineers of the subway project team found that: The task of designing a fanless cooling system and video playback is very contradictory. The power of high-performance CPUs that can be purchased on the market is between 50w and 120w, plus other yuan. The energy loss of the device, the power of the machine can be normal operation around 200w. This undoubtedly gave the project engineer a big problem: In such a large power consumption, passive cooling fins should be used for heat treatment of the machine. The size of the heat conducting iron sheet should be at least 0.5 square meters. Table-sized heat sinks are not acceptable to customers anyway. The project team through the measurement and control system and arbor company's cooperation, hoping arbor's hmi department can help solve this problem. Arbor's R&D engineers have been researched and certified several times. Combined with the advantages of intel's partners, they chose the intel atom n270 high-performance and low-power cpu processor, which enabled the power consumption to be around 36w, and then added arbor's special patented process. , Successfully developed the subway media player-arpex-2610. Similarly, after the rigorous testing and actual operation of the machine by the subway project team, arpex-2610's trouble-free operation time is stable at 50,000 hours, can support windows and linux multiple operating systems, and through ce, fcc, ul and many other international Certification. 3.3 arpex-2610 features (1) intel atomtm n270 1.6ghz 32-bit x86 cpu core; (2) Supports maximum 1600 & TImes; 120 (4:3) dvi output; (3) Built-in symbol lcm module; (4) Isolated serial port (rs-232/422/485); (5) Built-in free opc driver (only wince system version); (6) Passive cooling system (fanless); (7) Support wireless function (optional); (8) Memory backup can restore data indefinitely; (9) Easy installation/replacement of storage devices; (10) 2d/3d graphics accelerator. 3.4 Arpex-2610 based streaming media system Dedicated host model: arpex-2610; operating system: winxp; cpu processor: intel atomtm n270; system memory: 2g; storage medium: 160g hdd; network: dual gigabit + wlan. The streaming media playback system based on Acer arpex-2610 host is shown in Figure 4. Figure 4 streaming media system Rail transit is the only way for large and medium-sized modern cities in developed countries to solve public transportation. Rail transit is characterized by safety, comfort, convenience, and efficiency as the best solution for large cities to solve traffic structures, build a three-dimensional transportation network, solve traffic problems, and improve the urban environment. The efficient and safe operation of rail transit is a vast engineering area of ​​industrial computer ipc and embedded automation systems.

1. Size: Usually the size is the size of a mobile phone.
2. Battery life: It is required to have at least 1-2 hours or more of battery life without power connection. In addition, its general weight will not exceed 0.2Kg, and some do not even need fan cooling or ultra-small silent fan cooling. Can be carried with you (it can be put into a pocket, the screen can be projected to 40-50 inches or more, so sometimes we also call it a pico projector or a pocket projector.)
