Security and protection keyboard code element matching method and device

The invention belongs to the field of safety monitoring and controlling and provides a security and protection keyboard code element matching method and a device. The method comprises the following steps of firstly, coding buttons of a keyboard; building a first two-dimensional table, wherein the first two-dimensional table comprises codes, button names and code elements corresponding to the button names in each ball control protocol; building a plurality of chain tables according to the first two-dimensional table, wherein the chain tables are in one-to-one correspondence to the ball control protocols; acquiring a target protocol of a current keyboard from the ball control protocols according to protocol selecting operation sent by a user, wherein the target protocol corresponds to one target chain table; feeding back target codes according to button operation sent by the user; finally, when the target codes and elements in the target chain table are matched, acquiring target code elements corresponding to the target codes from the target chain table, and carrying out keyboard commands corresponding to the target code elements. Through the security and protection keyboard code element matching method and the device, the matching efficiency of the security and protection keyboard code elements is improved.
