Rail transit electromechanical installation engineering safety supervision early warning method and monitoring system

The invention relates to a rail transit mechanical and electrical installation engineering safety supervision early warning method and monitoring system, and belongs to the technical field of rail transit mechanical and electrical installation. The method comprises the steps that during construction, first image information of the installation position of certain type of mechanical and electrical equipment is acquired; whether second image information matched with the first image information exists or not is searched in a preset non-standard type library, if yes, construction safety specification standard terms associated with the second image information in advance are obtained, and first early warning information is output. During construction, the first image information of the installation position of the electromechanical equipment can be obtained, the second image information matched with the first image information is searched in the nonstandard type library, and if the second image information matched
