Pantograph catenary system monitoring method and system

The invention discloses a pantograph catenary system monitoring method and system, and is applied to a data terminal, and the data terminal is connected with various types of monitoring devices. In the pantograph catenary system monitoring method, the data terminal obtains monitoring information transmitted by the various types of monitoring devices connected with the data terminal first, then the monitoring information is parsed, and therefore whether defects exist in each acquisition place of the pantograph catenary system or not can be determined. Compared with the prior art, the pantograph catenary system monitoring method is advantaged in that workers do not need to go to different installation sites, parameters acquired by the monitoring devices can be obtained through the data terminal, and whether defects exist in each acquisition place of the pantograph catenary system or not can be determined. Thus, the monitoring speed is increased, the monitoring time is saved, and manpower can be saved.
