摘要：【中文】本发明公开了一种矿用无轨胶轮车防爆车载计价器，包含计价器主机、转速传感器、红外测距传感器、便携式打印机、红外遥控器、IC卡读写器和IC卡。计价器主机安装在无轨胶轮车的驾驶室内，转速传感器安装在发动机风扇旁和轮毂旁，红外测距传感器安装在车辆尾部，便携式打印机和IC卡由驾驶员随身携带，红外遥控器和IC卡读写器由地面管理员管理。计价器主机通过两个转速传感器来判断车辆的状态，并根据不同的状态进行计价。计价器主机通过四个红外测距传感器实现倒车报警功能，计价结束后可通过便携式打印机打印本次行程票据。该发明考虑了矿用无轨胶轮车的计价特殊性，能够实现分状态计价、计价信息实时显示、时间显示、数据存储、倒车报警等功能。 【EN】The invention discloses an explosion-proof vehicle-mounted taximeter for a mining trackless rubber-tyred vehicle, which comprises a taximeter host, a rotating speed sensor, an infrared distance measuring sensor, a portable printer, an infrared remote controller, an IC card reader-writer and an IC card. The main machine of the taximeter is installed in the cab of the trackless rubber-tyred vehicle, the rotating speed sensor is installed beside the engine fan and the hub, the infrared distance measuring sensor is installed at the tail of the vehicle, the portable printer and the IC card are carried by the driver, and the infrared remote controller and the IC card reader-writer are managed by a ground administrator. The main machine of the taximeter judges the state of the vehicle through two rotating speed sensors and carries out pricing according to different states. The meter host machine realizes the function of backing alarm through four infrared distance measuring sensors, and the travel bill can be printed through the portable printer after the metering is finished. The invention considers the pricing particularity of the mining trackless rubber-tyred vehicle and can realize functions of state-based pricing, pricing information real-time display, data storage, backing alarm and the like.
