APPLICATION CASE 1 OK335xS-II Applied in Pro-environment Nowadays, Green Economy has become the major momentum and trend worldwide. In China, with economy globalization and the go-out state strategy, domestic pro-environment industry has also to face international competition. Through 3 decades’ development, Chinese pro-environment industry now consists of pro-environment products, cleaning product, environment service, resource recycling and ecological protection. Recent years, owing to self-R&D, import and digestion, the gap between our pro-environment technology and that of overseas has narrowed, some even reaching international level. As a professional embedded control platform manufacturer, Forlinx Embedded provides ARM development platforms for many enterprise clients. In solutions for pro-environment digitalization, OK335xS-II is adopted, which is based on TI Cortex-A8 architecture with industrial MPU—AM335X. By integrating core technology and modern communication technology, this solution could capture and monitor related data of waste water and gas, conduct automatic, instant, large-scale and 24-hour’s mark, capture, transfer and analysis of them, which guarantees efficient, high-density, elaborate and prompt environment information. It boosts fundamental reform in environment surveillance and ability by providing IT support and service for environment management, monitor and decision-making. 1. Hardware for capturing and transferring data 1.1 Chassis: wall mount, simple and easy to install 1.2 Hardware: Forlinx FET335xS-II + base board 1.3 Long-distance communication: To apply to different communication networks, data transfer terminal needs to be of following interfaces and modules: a. Dual industrial Ethernet port b. 1 GPRS module, one 3G module, 1 WIFI module. To ensure data security in wireless communication, terminal should be able to encrypt and decode all data which is realized by hardware encryption modules via USB port. c. Multiple communication types. All communication networks and WIFI in all monitor spots are available to satisfy all kinds of need. 1.4 Data capture Via monitor terminals, data capture terminal could get all status and analog surveillance data, including emission concentration and load of waste water, waste and exhaust gas, environment temperature and humidity. As a result, following data capture interfaces are necessary: a. Dual Ethernet port for intelligent monitor terminal and camera b. 4 RS232/485 adaptable interface for monitor terminal c. Ten 12-bit analog input interface d. 8 GPIO interfaces e. 4 output control interface f. 1 SD card slot 1.5 Core hardware technology: FET335xS-II CPU module a. High-performance industrial processor TI ARM Cortex-A8 AM335X b. 6 serial port, internal CAN controller c. Dual Gigabit Ethernet port d. Low power consumption e. 16-bit data bus (multiplexed with address bus) and 12-bit address bus f. working temperature: -40℃~+80℃ g. 2 USB 2.0 h. support Linux3.2 1.6 7-inch resistive LCD 1.7 Power supply Independent solar power supply in form of module 1.8 Schematics of capture & transfer terminal Note: part in orange is Forlinx FET335xS-II CPU module.

Software for capturing and transferring environment data Software for terminal is based on ARM Linux3.2, consisting of software support platform, exchange configuration management, application software and system management. 2.1 Data terminal captures and stores surveillance data collected by different monitor devices and transfer these data through different communication network and host station. In this case, terminal needs to possess following functions; a. Capture data: collect data sent by surveillance devices and integrate them together. It supports both automatic and controlled capture. b. Communication: make long distance data-transfer and surveillance according to communication network. This will not only save long-distance communication resources, but also shield traditional long-distance interferences. Data could be cached when transfer breaks off and be transferred automatically when channel comes normal. c. Specification switch: make specification switch according to configured specification library. Data collected by different devices with different brands could be disposed, stored and uploaded with unified format. d. Low power consumption: the controller will dynamically control all modules’ power consumption and working status, that is, going into sleeping mode or cut-off status. e. Others. Encryption, parameter configuration, event storage, online update and local maintenance. For more details of OK335xS-II single board computer, please visit forlinx.net/?p=26&a=view&r=110
