Deformation monitoring device, method and deformation monitoring deformation monitoring system granary

The present invention relates to the object of the present invention is to provide a monitoring device deformation, deformation monitoring methods and granary deformation monitoring system for monitoring low address existing silos deformation degree of automation, the cost is high. One kind of deformation monitoring device, characterized in that the deformation monitoring device, comprising at least a set of laser communication devices, each device is composed of a laser active communication module and a corresponding response module, in response to the active module and the modules are provided for emitting laser light laser and a photoelectric conversion signal for receiving the laser signal. Due to its linear transmission principle using a laser, so that the cartridge granary structure deformation monitoring problem is solved difficult to monitor; can be achieved without the actual data transmission between the monitoring line and a position control circuit, to avoid the fire safety line brought dispatched risks.
