场强是保证无线列调电话畅通的必要条件。由于经济及技术条件的制约,多年来我国铁路无线列调的场强测试均采用人工测试的方法,给电务部门在人力、物力、财力上造成很大困难和浪费。此外,有时由于地面发信人员对测试要求不清楚,造成错发、漏发、长发等现象,使在该区间的测试失败。特别是在边远地区和交通不方便的铁路地区,搞一次场强测试,繁杂的数据处理及表格生成等工作,使得测试结果的汇总需较长时间才能完成。近年来,铁路各单位在改进场强测试方法、提高效率与精度方面做了大量工作,但全自动测试一直未能实现。针对以上情况,乌鲁木齐铁路局电务处与北方交通大学通信与 Field strength is to ensure that the wireless dial phone calls the necessary conditions. Due to the constraints of economy and technical conditions, the test of field strength of railway wireless alignment in our country for many years has adopted the manual test method, which has caused great difficulties and waste in manpower, material and financial resources for the electricity service department. In addition, sometimes the sender of the ground does not know the test requirements, causing errors, missing hair, long hair and other phenomena, thus failing the test in this interval. Especially in the remote areas and the transportation is not convenient rail areas, engage in a field test, complicated data processing and form generation work, making the summary of the test results take a long time to complete. In recent years, various railway units have done a great deal of work in improving field strength testing methods and improving efficiency and accuracy, but fully automated testing has not been realized. In response to the above, Urumqi Railway Bureau Department of Communications and North Jiaotong University communications
