摘　　要：针对智轨电车的传统制动控制系统集成度不高、调压精度低、网络通信性能差和可维护性不足等现状,文章提出一种新一代电空制动控制技术。在电子控制部分,其将传统的制动控制和压力调节模块合二为一,形成集成电控单元;在调压集成模块部分,其将压力调节阀、应急电磁阀、远程缓解阀等多个功能阀集成到一个模块中,简化了气路布局,优化了安装空间,集中了控制功能。该电空制动控制系统采用在轨道交通领域充分验证过的压力调节阀,联合电控单元新型调压算法,使得压力调节更稳定、精度更高且调节阀动作次数更少;同时,采用双以太网架构,较传统CAN通信,数据传输数量和效率提升了数十倍,网络通信能力和可维护性水平得到了较大提升。目前,该制动控制系统已完成地面联合测试和第三方的整车测试,并在最新的氢能源智轨电车上装车运用,综合性能优异。Considering the current issues such as low integration,imprecise pressure adjustment,poor network communication performance,and lack of maintainability in traditional braking control system of autonomous-rail rapid tram,the paper introduces a new generation of electro-pneumatic braking control technology.In the electronic control section,the traditional braking control and pressure regulation modules are combined into an integrated electronic control unit.In the pressure regulation integrated module section,multiple functional valves such as pressure regulating valve,emergency solenoid valve,and remote relief valve are integrated into one module.This simplification of the air circuit layout optimizes space use and centralizes control functions.This electro-pneumatic braking control system employs a pressure regulating valve that has been fully verified by rail transit,coupled with a new pressure regulating algorithm of the electronic control unit,making pressure regulation more stable,with higher accuracy and fewer actions.Additionally,the application of dual Ethernet architecture enhances data transmission quantity and efficiency by several times compared to traditional CAN communication,considerably improving network communication capabilities and maintainability levels.The braking control system has completed ground combined test and third-party vehicle test,and has been installed and applied in the latest hydrogen energy autonomous-rail rapid tram,demonstrating excellent overall performance.
