Background
In order to test the safety and reliability of the full electronic fuse, a full electronic fuse tester is developed, which is a necessary supporting work in the fuse design. In recent years, a full-electronic fuze tester taking a single chip microcomputer and an ARM chip as cores is gradually developed. Because the control function is relatively strong, automatic control and test are gradually realized, and the test result is an important basis for judging the quality of the fuze. However, as the technology of all-electronic fuzes and communication technologies continue to develop, the technology of communication of the fuzes on the bomb has also been greatly developed. Therefore, the conventional fuze tester without the data binding interface cannot meet the data binding test requirement of the all-electronic fuze.

But there is no communication interface between the tester and the fuze for binding data transmission. Therefore, the tester does not have the function of data communication with the fuze in a binding mode, and cannot bind critical data of fuze actions in real time; by section 1.1: the electronic safety system tester completes the detection of the fuze function in a one-key and indicator light mode, and can also find that the tester detects through a one-key metal key starting signal without a numeric keyboard, so that parameters needing to be bound cannot be input; meanwhile, the result display mode of the indicator light cannot display the information bound by the fuze in real time.
Therefore, novel test equipment which can bind data in real time and meet the complex requirements of a fuze test system is developed, and the test equipment can better meet various fuze test requirements of troops and the convenience of performance debugging and product inspection before products leave a factory.
And setting binding parameters by using a metal keyboard of the tester, and storing binding data by the tester after the setting is finished. Before the tester sends a release and trigger control instruction to the fuze, binding data transmission between the tester and the fuze is completed, so that the fuze receives the binding data, and the operation of binding the set parameter data of the upper computer is completed. And finally, carrying out fuse data read-back display through a display screen.
