ABSTRACT:
A system for remotely programming a mine includes a programming device comprising a computer having a data memory storing functions required to control the mine once laid, a code word memory and a random number generator. Stored data is displayed on an output device. A random number generator generates random numbers corresponding to respective addresses in data memory under which selected displayed functions are stored. The random numbers are stored as code words, together with corresponding data memory addresses, in the code word memory. A transmitter connected to the computer transmits the contents of the code word memory. A programmable electronic unit in the mine includes a receiver and a second computer. The second computer has a second code word memory for storing the transmitted code word memory, and a second data memory corresponding to the data memory of the programming device storing identical data. The second computer correlates a subsequently received code word with a code word previously stored in the second code word memory so that the function in the second data memory stored under the address corresponding to the subsequently received code word can be carried out.
