Inspection well lid condition monitoring device with ultra low power consumption

Abstract

Provided is an inspection well lid condition monitoring device with ultra low power consumption. The inspection well lid condition monitoring device comprises an inspection well lid condition detector, an MCU and an RF transceiver, wherein an output interface of the inspection well lid condition detector is electrically connected with an input interface of the MCU; a data interface of the MCU is electrically connected with a data interface of the RF transceiver. The inspection well lid condition monitoring device with ultra low power consumption is characterized in that the inspection well lid condition detector is composed of a radio signal strength detection circuit. By adopting the inspection well lid condition monitoring device with ultra low power consumption, a very high ratio of sleep time to operation time can be obtained under the condition that a zero omission ratio is guaranteed, and power consumption is very low; with the low power consumption characteristic, the inspection well lid condition monitoring device also has the advantages of being simple in circuit and low in cost, thereby opening up a novel way for automatic monitoring of conditions of an inspection well lid.

Description

technical field [0001] The invention relates to an on-line monitoring technology, in particular to an on-line monitoring of the state of a manhole cover. Background technique [0002] Electricity, communication, water supply, gas supply, cable TV underground tunnel entrance and exit inspection well cover is the key device for entering the underground tunnel for overhaul and maintenance, and these entrances and exits have become the key nodes to ensure the normal operation of these systems. Due to the complex environment of entrances and exits, harsh conditions, and sensitivity to costs, the technical difficulty of implementing monitoring management is high, the investment in research and development is large, and the results are slow, so that there has been no substantial progress in the monitoring of inspection manhole covers at the entrances and exits of underground tunnels for a long time. [0003] With the continuous advancement of science and technology, the application...
