摘　　要：在工程车辆制动距离测试中,传统的目测法存在精确度不高、随意性大、过于依赖测试经验等缺点。随着实时动态(Real Time Kinematic-RTK)测量技术的不断发展,当前RTK GPS接收机的定位精度与数据输出速度已经可以满足工程车辆制动距离的测试要求。构建基于ARM9处理器的GPS测试系统,并引入RTK测量技术对制动距离进行测量,取得了稳定、精确的测试效果。During the brake distance test on construction vehicles,there are some defects in the traditional visual check such as low precision, high randomness, and over-reliance on test experience. With the continuous development of RTK (Real Time Kinematic) measurement technology, the RTK GPS receiver's allocation accuracy and data output speed could satisfy the requirements of brake distance test for the construction vehicles. Construction of a GPS test system based on the ARM9 processor together with introduction of RTK measurement techniques to measure the brake distance has got a stable and precise test effect.
