The invention relates to electric power on-site monitoring equipment which adopts a pluggable distributed structure. The electric power on-site monitoring equipment comprises one or more chassises and chassis backboard circuit board(s) and communication connectors among the chassises, wherein each chassis comprises a communication processing board based on an ARM (Advanced RISC Machine) processor, one or more analog quantity processing boards based on a DSP ( Digital Signal Processor), one or more state quantity and switching quantity processing boards based on the DSP, one or more interface boards matched with the current signal or the voltage signal conversion and isolation of the analog quantity processing board, one or more interface boards matched with the isolation state and the switching of the state quantity and switching quantity processing board(s) and a power panel which supplies power for the chassis equipment and can charge and discharge storage batteries. According to the electric power on-site monitoring equipment, the requirements on railway construction in China are sufficiently satisfied; multi-CPU (Central Processing Unit) distributed computation and high-density acquisition satisfy the demands of the on-site capacity; the electric power on-site monitoring equipment has a fault recording function and effectively distinguishes fault properties; and multi-stage isolation access satisfies the requirements on the on-site strong electromagnetic field environment and is safe and reliable.
Description
technical field [0001] The present invention relates to the field of electric power monitoring, in particular to a field electric power monitoring equipment, which is equipped with high-precision acquisition and wave recording of electric power parameters, reliable control of electric power equipment, standard Ethernet communication and routing, remote maintenance and update, equipment Board plug and play and other functions. Background technique [0002] In order to respond to the policy needs of the country to increase domestic demand and the needs of the development of the national passenger express railway, it is necessary to carry out remote monitoring and local automatic control of the power equipment along the railway and in the railway station building. In the traditional technology, a power signal monitoring device is usually installed locally, and the device has a communication function. However, the RTU (remote terminal unit) equipment in the existing domestic an...
