The invention discloses a
monitoring system for monitoring the real-time status of damage, upwarp and theft of a pit well cover. The
monitoring system comprises the pit well cover (1), a strain thin conducting wire (2), a
voltage source (3), a triaxial acceleration sensor (4), a micro
control unit (MCU) (5), a
wireless transmitting terminal (6), a sampling
resistor (7), pit well cover monitoring instruments, an information collecting and gathering device,
general packet radio service (GPRS) far-transfer modules, pit well cover monitoring subsystems and a general control console, wherein the
voltage source (3) is connected with the strain thin conducting wire (2), the MCU (5) and the sampling
resistor (7); the strain thin conducting wire (2) is connected with the triaxial acceleration sensor (4) and the sampling
resistor (7); the triaxial acceleration sensor (4) and the sampling resistor (7) are connected with the MCU (5) connected with the
wireless transmitting terminal (6); the pit well cover monitoring instruments are connected with the information collecting and gathering device; and the information collecting and gathering device and the pit well cover monitoring subsystems are respectively connected with the GPRS far-transfer modules connected with the general control console.
