Abstract

The invention discloses a safety monitor comprising a single chip microcomputer, a gravity sensor, three-phase input voltage and a relay, wherein the three-phase input voltage is accessed into the single chip microcomputer through a filter circuit; the gravity sensor is accessed into the single chip microcomputer through an amplification circuit and the filter circuit; and the single chip microcomputer controls the action of the relay. The single chip microcomputer is used for detecting whether the three-phase input voltage is lack of phase; and the safety monitor displays a failure cause when the three-phase input voltage is lack of phase. The safety monitor is used for managing and protecting a crane, adjusting the use of the crane and preventing the crane from operating when a potential hazard condition is probably caused. The safety monitor can realize overload protection on the crane, monitor the operation of the crane, failures, phase sequence of a main power supply, phase lacking of the main power supply as well as control the voltage, achieve low-speed starting and low-speed stopping functions, record operation time, and implement relay output and tonnage display.

Description

technical field [0001] The invention relates to the monitoring field, in particular to a safety monitor. Background technique [0002] Crane equipment has a consideration of working conditions and service life at the beginning of design. At the same time, crane equipment needs protection and management during use. There is no complete control device or control element formed to complete this function at present. Contents of the invention [0003] Aiming at the above-mentioned problems existing in the prior art, the present invention provides a safety monitor. [0004] The invention provides a safety monitor, comprising: a single-chip microcomputer, a gravity sensor, a three-phase input voltage and a relay; the three-phase input voltage is connected to the single-chip computer through a filter circuit, and the gravity sensor is connected to the single-chip computer through an amplification circuit and a filter circuit; the single-chip computer controls the relay Actions....
