智能交通是当今智慧城市的支柱。全球各地的智慧城市通过采用不同的技术发展智能交通系统，引领着交通网络管理、机场和车站管理、桥梁和水路管理的未来发展。
瑞传科技(Portwell, inc.)在智能交通相关产品线方面拥有丰富的经验，我们有专门的团队为交通开发商提供定制化的产品和服务。我们不断努力为全球智能交通和智慧城市的发展做出贡献。
瑞传科技在智能交通應用上，深知铁路管理的复杂性和特殊规定，長達30年的客戶服務經驗，我们可以根据不同的应用需求設計產品，來遵循相关的规定。
瑞传科技的铁路解决方案包括户外、室内和列车内应用。对于户外解决方案，我们除了满足环境温度和高湿度的要求外，并支持多种无线通信系统以确保信息流动；对于列车内解决方案，机车的供电规定与其他应用非常不同，我们的產品必须滿足防振动的設計，以確保系统運作穩定。也因為如此，所有瑞传科技的铁路解决方案，都必须根据客户的智能交通应用需求具备以下特点。
我们的铁路解决方案需要符合EN50155标准，该标准涵盖了用于铁路应用的滚动设备上使用的电子设备，以及符合EN50121标准的电磁兼容性。根据客户的要求，我们还需要遵循日本的JIS E 5006标准和美国的ARIMA第11节要求。
因为用户在产品的应用环境各不相同，例如户外和海滨地区。瑞传科技的智能交通铁路解决方案，均具备防水和防腐蚀设计，甚至使用PCB涂覆材料来防止损坏。
瑞传科技可为客户提供12V-36V和72V-110V的电源输入系统。电源设计需要满足并遵守铁路规定。在设计阶段，我们必须与客户进行讨论，并严格控制每一种材料的使用。
在火车行驶过程中，机车系统会产生振动，瑞传科技的铁路解决方案中，抗震和抗振动是标准配置。我们从连接器、电缆、存储器、存储设备到整个系统层面都进行了抗冲击和振动的设计。
瑞传科技的铁路解决方案采用广泛的温度范围设计，可在-40至70摄氏度的室外温差条件下运行，以满足系统对温度的要求。我们致力于确保系统的稳定性，以保障一切的安全性。
为确保连接设备的安全性，我们在原理图和PCB布局中隔离了每个IO，并采用M12连接器设计，以确保电线连接紧密而稳固。
There are infotainment systems to communicate with passengers in the modern transportation, the basic function is the broadcast system to show bus information and current location. In the bus infotainment system, how to maintain the stability of the bus power supply system and integrated power ignition signal status are the key in the design. In this case, infotainment system connected with bus battery directly, after discuss with customer… [Read more]
When there is a critical railway accident, a locomotive data recorder is the key to find out the reason why the accident happened, then analyzed all the data within to get the conclusive result.
In the development of railway systems, we incorporate the CHMM(Crash-Hardened memory module) within the system with high speed I/O and manage all information concurrently to make sure all critical information can pass into the data recorder in a correct sequence with no latency…[Read more]
Safety has always been the most important topic in railway transportation, how to reduce railway level crossing accidents is very important. In the past, level crossing alarm only when the locomotive is coming, now the railway transportation system develop surveillance control system, however, more intelligence is needed in the upcoming future railway systems… [Read more]
Airport managements all over the world are developing digital systems. In tradition, there are a lot of customs officers to keep passengers passing customs fast. With labor costs rising, automated border control systems become more and more valuable. When passengers pass through customs, the automatic gate control system(eGate) identifies passengers’ personal biometric features and then open the gate to allow passengers to pass quickly and safely. After COVID-19… [Read more]
