Online monitoring node device of passenger train running preparation and overhaul power supply and protocol conversion method

Abstract

The invention relates to an online monitoring node device of a passenger train running preparation and overhaul power supply and a protocol conversion method, aiming at solving the problems in a utilization process of the air-conditioning passenger train running preparation and overhaul power supply of a railway transport enterprise of acquisition of power consumption information, power consumption time and exceptional power consumption, a plurality of types of transmission manners and protocol conversion thereof. The node device comprises a main control computer, a storage module, a time module, a multiplexer, a setting module, a 232 module and / or a 485 module; a tailorable mixed data transmission module comprises a ZigBee module, and / or an Ethernet module, and / or a GPRS (General Packet Radio Service) module; the mixed data transmission module is selected according to conditions of a power supply field and short-distance and long-distance data transmission is realized; a node can be used independently and can also be networked; the node device selects a transmission manner according to the difference of field conditions of the railway transport enterprise; and a protocol self-adaptive conversion method is adopted, the used data transmission manner is automatically selected and a related protocol is converted.

Description

technical field [0001] The invention relates to the field of energy-saving online monitoring and the application field of network technology, in particular to an online remote monitoring device and protocol adaptive conversion method for ground power consumption information, power consumption time and abnormal power consumption of air-conditioned passenger cars. Background technique [0002] Passenger cars implement regular inspection and maintenance system. When the air-conditioned buses in the depot are overhauled in the maintenance depot, different types of ground power supplies are required to ensure daily maintenance and pre-cooling and preheating in winter and summer. At present, the external power supply or ground power supply used in the maintenance of passenger cars includes two types: three-phase AC 380 volts (3AC380V) and direct current 600 volts (DC600V). According to the maintenance and maintenance regulations, the electric load of the vehicle shall not exceed ...
