Multi-screen interface information synchronization method and device

An embodiment of the invention discloses a multi-screen interface information synchronization method and a multi-screen interface information synchronization device. The method includes steps of sending an initial image display command to a main screen interface so that the main screen interface displays the initial image according to the initial image command; using a real-time image signal of amain screen interface display zone; sending the real-time image signal of the main screen interface display zone to a screen interface so that the display zone of the screen interface displays the real-time image which is the same as the main screen interface display zone. The multi-screen interface information synchronization method provided by the embodiment has the advantages of realizing the synchronous display of the multi-screen local interface information and further realizing the purpose of facilitating workers to record detecting data through arranging multiple slave screens at different positions, and improv
