产品详情：TMU4交通轴信号处理器

        The HI-TRAC® TMU4 is a high speed trafficdata collection system recording vehicle classifiation and axle load data without interruption to traffi flow.The HI-TRAC® TMU4 incorporates embedded Ethernet with TCP/IP stack, VPN and FTP as well as extensive 8 Gb data storage and thus provides high-end functionality at a reasonable cost.The standard configurationof two Class 1 piezo electric sensors and one inductive loop installed in the highway per lane provides axle weight data to COST 323 Class B(10) accuracy in addition to inter-axle spacing and vehicle speed data.The system can be used as a statistical data device to record highway trafficloading or it can also be used as a screening weighbridge to identify overloaded vehicles in the traffic steam.The HI-TRAC® TMU4 can be interfaced to trafficsignals or diversion signs to intercept overloaded vehicles and to ANPR or CCTV camera systems.The HI-TRAC® TMU4 uses TDC Systems advanced loop profilig techniques to improve vehicle classificationaccuracy and weight data is significantl improved with advanced automatic temperature compensation algorithms incorporated as standard.
