Terminal block monitoring device

A terminal block monitoring device comprising:

• a current detection unit (12) provided in a terminal block (10) connecting a wire (20), so as to detect a current flowing through the wire (20);
• a temperature detection unit (14) provided in the terminal block (10) so as to detect a temperature of the terminal block (10);
• a tube (50) made of an elastic material so as to be provided horizontally on a ground in front of the terminal block (10);
• a first pressure sensor and transmitter module (52) provided at one end of the tube (50) so as to detect a change in pressure when a specific part of the tube (50) is stepped on and pressed by an approaching person, and thus transmit a first pressure detection signal;
• a second pressure sensor and transmitter module (54) provided at an opposite end of the tube (50) so as to detect a change in pressure when a specific part of the tube (50) is stepped on and pressed by an approaching person, and thus transmit a second pressure detection signal;
• a reception unit (60) for receiving the first and second pressure detection signals;
• and
• a monitoring control unit (16) provided in the terminal block (10) so as to receive a current detection value provided from the current detection unit (12), a temperature detection value provided from the temperature detection unit (14), and the first and second pressure detection signals provided from the reception unit (60) and provide the received values to a central management center (40) through an information communication network (30), and thus the central management center (40) monitors the terminal block (10) with respect to current and temperature and monitors a person approaching the terminal block (10), and
• further comprising:
• a pressing location determination unit (70) that receives the first and second pressure detection signals provided from the reception unit (60), determines a pressing location (56) of the tube (50) based on times of receiving the first and second pressure detection signals, a difference between the times of receiving the first and second pressure detection signals, a length of the tube (50), and a pressure change transfer rate subject to a specific part pressed inside the tube (50), provides the pressing location to the monitoring control unit (16), and allows the monitoring control unit (16) to provide the pressing location (56) to the central management center (40), so that the central management center (40) monitors a location of a person approaching the terminal block (10).
