FIELD: information technologies.
SUBSTANCE: automated equipment monitoring device for electrical substation comprises a computer connected to a sensor for metering the parameters of substation equipment. The computer is designed as a microprocessor-based data acquisition and processing unit. The sensors themselves are installed outside the sensors and connected with them using one or two fiber-optic cables. The cables are respectively connected to optical signal generator and receiver, either integrated or separated. The microprocessor and sensors are arranged in a single housing, which is fitted with a power supply, a display and an interface module. The sensors are connected to the personal computer by means of electrical or fiber optic connection. The sensors can be formed as current, voltage and temperature sensors. The microprocessor comprises a microcontroller connected with a Profinet and / or Ethernet communication module, ROM and RAM-1 memory as well as with a data controller to which RAM-2 with the ring buffer and the switching board with input sensor signals are connected. The microprocessor unit output is connected via Profinet and / or Ethernet network with the operator station.
EFFECT: improvement of reliability and versatility of monitoring devices.
