Radio frequency source locator

Abstract

The invention discloses a radio frequency source locator. The radio frequency source locator comprises a tablet personal computer, wherein a signal processing device is arranged on the rear side of the tablet personal computer, and the signal processing device comprises a signal acquisition module, a signal processing unit module, a signal amplification module, a data analysis module, a data storage module, a control panel and a power supply device. The radio frequency source locator is advantaged in that whether functions of a train tail safety protection device, plane shunting lamp display equipment, a GMS-R communication system, other private network communication equipment and a contact interphone are good or not is detected, close correlation between railway productivity and transportation safety is improved, intangible signals are converted into data to be presented, and the equipment is portable, is carried by a worker to work, can check a state of external radio frequency activity in real time, judges whether an external electromagnetic environment is good or not, can track, position and search an interference source, can accurately and quickly find the interference source,eliminates hidden dangers, and guarantees high efficiency of railway transportation and production safety.

Description

technical field [0001] The invention relates to the technical field of radio frequency inspection equipment, in particular to a radio frequency source locator. Background technique [0002] When the radio communication equipment works well, it also has extremely high requirements on the external electromagnetic environment. With today's development, the use of radio frequency resources in many countries is also very tight, and the occupancy rate of radio frequency resources is high. This has caused the problem that the radio frequency used in our railway production is occupied or interfered, which affects the efficiency of our railway transportation and Safety has laid a great hidden danger. Most of the communication abnormalities in field operations are found by the "replacement method" of replacing equipment, that is, replacing the equipment one by one until the fault is eliminated. If it is not resolved, replace the on-board equipment. Generally, this kind of failure o...

Problems solved by technology

Generally, this kind of failure occurs before driving, so this method is time-consuming and wastes manpower and material resources, but it may not be able to find the root cause, because it may not be a device failure, it is very likely that the radio signal encountered interference during propagation, causing The bit error rate of the receiver is high, and the failure caused by the inability to fully identify it, resulting in poor on-site communication, leads to accidents
