Description

Pit covers damage, tilt, stolen real-time status monitoring system

FIELD

[0001] The present invention relates to a monitoring system, in particular to a breakage pit covers, tilt, real-time condition monitoring system stolen.

Background technique

[0002] At present, the city is not a real-time status monitoring of its large number of pit covers, causing a lot of damage because the pit covers, tilt, can not be stolen, find and correct the occurrence of serious accidents, to the community and the people of life and property caused significant losses.

SUMMARY

[0003] The object of the present invention: breakage discloses a pit covers, tilt, real-time condition monitoring system stolen.

[0004] To achieve the object of the present invention, a technique to be adopted: There manhole cover, strain thin wire, a voltage source, a triaxial acceleration sensor, MCU, wireless transmitter, the sampling resistor, the manhole cover further comprising a monitor, information collection set exchange devices, GPRS remote module, the monitoring subsystem manhole cover, total console. Strain wherein the voltage source is connected thin wires, and the MCU sampling resistor, thin wires connecting the strain triaxial acceleration sensor and sampling resistor, the triaxial acceleration sensor and a sampling resistor MCU, MCU connected to the wireless transmitter. Manhole monitor connected to the information collection sinks, spider sinks GPRS remote connection module, a GPRS connection manhole cover remote monitoring sub-module, a GPRS module connected to the main remote console.

[0005] The present invention covers damaged pit, tilt, real-time status monitoring system is stolen, you can use the new, the old pit covers and use them to transform the city-the city actually used, monitored by computer platforms. Whether using the detected lay cables damaged manhole cover, as judged by real-time detection of the inclination angle of the manhole cover or reveal whether it is stolen and read in real time the pitch angle, the transmission of data between a wireless transmission system to the total console, when the manhole cover damaged, stolen or being turned up the system issues a warning. Covers for damage to the analog monitoring, we simulated covers soft strain spread in a thin wire, a thin wire connecting the voltage source strain, damage to the covers, strain flexible thin wire is disconnected, the wires are not current, the wire by monitoring in determining whether a current can simulate covers is damaged, if the test system to work properly, we can switch to connect several lines laying process, as analog break point, when the switch is turned off, to see whether the system can be monitored in real time change in the current conductor, and also to test the alarm module and the wireless transmission module is active; in order to monitor whether the covers are turned up, we installed a triaxial acceleration sensor by measuring the change in static acceleration of gravity, it is converted into a change in the tilt angle covers. Measuring the output of the sensor and inclined with respect to the horizontal pitch angle, MCU reads the pitch angle can be determined whether the covers turned up. Data transmission using a wireless transmission technology, changes in the angles of inclination of the wire current and analog covers MCU transmits information read by the wireless transmitter imputation sinks, and then transmitted to the console using the total mobile communication network through GPRS remote module , remote console module receiving data through the GPRS, the information read and make a judgment, if the breakage occurs or is found to reveal the analog covers, a warning is issued.

[0006] The invention enables rapid, real-time and accurate monitoring of the manhole cover, and long life, good waterproof, anti-vibration performance.
