瑞士伯尔尼Hasler公司为澳大利亚国家铁路提供了12套机车用Teloc-2000D型全电子速度测量和记录系统。这些系统规定用于澳大利亚铁路AP42C型电力传动内燃机车。每套装置包括带RAM存储器的中央处理器、Servo速度指示仪、里程计数器和光学-电子脉冲传感器。这种Teloc-2000D型速度测量和记录系统,不仅记录3个模拟信号(指令速度0～180km/h,制动缸压力和制动管压力),还记录机车运行状态的14个数字信号、机车标志号和传到里程计数器的行程脉冲信号。所应用的RAM存储模件短时存储时间约15分钟,长期
Hasler, Berne, Switzerland, has provided Teloc-2000D all-electronic speed measurement and recording system for the Australian National Railways. These systems provide for the Australian Railroad AP42C electric drive diesel locomotive. Each unit includes a CPU with RAM memory, a Servo speed indicator, a speedometer and an optical-electronic pulse sensor. The Teloc-2000D speed measurement and recording system not only records three analog signals (command speed 0 ~ 180km / h, brake cylinder pressure and brake pipe pressure), but also records the 14 locomotive running state of the 14 digital signals, the locomotive Sign number and reach the mileage counter trip pulse signal. The RAM memory module used for short-term storage time of about 15 minutes, long-term
