Most of markets of the C3 communication modules on the train are occupied by foreign manufacturers such as Funkwerk and the like, and faults such as disconnection and overtime of wireless communication often occur. And the signaling and log recording analysis functions of the communication module are incomplete, so that the fault can not be effectively positioned and checked, the operation of a passenger line on the line is seriously influenced, and the CTCS-3 faults occur for 3975 times in the first half of 2016. And the domestic market is always blank in the aspect of communication modules on trains. Therefore, the existing signaling and logging system of the vehicle-mounted communication equipment has the following problems:

For example, although the overtime fault occurs frequently, the number of vehicles capable of recording fault logs is limited, effective comparison test cannot be performed, and the overtime fault cannot be eliminated completely all the time.
2. The failure log analysis efficiency is low, because the signaling analysis system of the existing communication module is controlled by foreign manufacturers, each electric service section of each route cannot independently analyze the failure log, the captured log must be sent to a specified agent company, the agent company analyzes the result, and the analyzed file can be checked only on a specific computer by using a specified authorization code. Therefore, the fault analysis time period is long, the operation process of each link is long, and the degree of understanding of technicians of the agent company on the special railway network is limited, so that the existing fault log analysis efficiency is low.
3. The existing signaling log system has incomplete information and cannot accurately point out a fault point.

This requires the cooperation of ground communication equipment, air interface signal transmitting/receiving equipment, vehicle-mounted communication equipment, and Automatic Train Protection (ATP) equipment. The method comprises the following steps that vehicle-mounted communication equipment on a train communicates with vehicle-mounted ATP equipment, the vehicle-mounted ATP equipment can send a degradation instruction to the train for control when communication is abnormal, the vehicle-mounted communication equipment further communicates with ground communication equipment of the ground equipment through air interface communication, and outputs an AT instruction, an AT instruction reply, an ATP control instruction, service data and the like which are interacted with the vehicle-mounted ATP equipment and the ground communication equipment; however, although the existing vehicle-mounted communication device can provide Igsmr monitoring signaling (service data received and transmitted), and AT commands and replies, it can only prove whether the communication module is in normal air interface communication with the ATP device and the ground device or ATP interaction is normal, but cannot acquire complete bottom layer information (such as module state, partial air interface state information, and the like), for example, the caused ATP fault may also be an ATP equipment abnormality, an ATP-sent control information abnormality, an ATP-radio connection abnormality, a radio station state abnormality, a radio station failure to execute an ATP command, and the like. And because ATP, communication radio station, ground side equipment relate to a plurality of technical fields such as signal, communication respectively, belong to a plurality of departments, fuzzy fault signaling has brought very big inconvenience to troubleshooting.

The service data comprises uplink service data and downlink service data, and the service data comprises an Igsmr monitoring signaling, air interface information and the like.
Specifically, the vehicle-mounted communication station is a communication junction between the ATP device and a radio block center RBC. When the train runs, the ATP equipment provides uplink service data for a Radio Block Center (RBC) through a vehicle-mounted communication radio station, and the RBC schedules the train according to the uplink service data provided by the ATP equipment. If the train has a wireless communication overtime fault, namely the ATP equipment judges that the network state is abnormal from the received data, the ATP equipment interrupts the communication with a Radio Block Center (RBC), and simultaneously sends a degradation instruction to the train to achieve the aim of decelerating or stopping the train.
