The invention relates to a method of forming fuses by improving the structure and redistribution of functions between the circuit elements of the fuse.
Ammunition equipped with fuses in accordance with the required actions. However, there are a large number of identical fuses different a small number of design parameters. Numerous attempts were made to reduce the number of types of fuses to an optimal number, but a simple reduction (simplicities) the problem has no solution.
The main reason for the ineffectiveness of this approach is that it is necessary to organize various kinds of technical devices, which is the result of many random solutions of this creative process as design.
In addition, improving the efficiency of the use of ammunition can be achieved through the use of a broader set of programs functioning fuses, adequate conditions of use, that is impossible with a simple reduction in the number of types.

The disadvantages of this method are the lack of taking into account the parameters of the external environment, the lack of selection of sensor and output actuators in the fuse depending on the actions of ammunition, and the use of elements with a common data format.
The proposed method of forming fuses eliminates these drawbacks.

The system consists of a constant core system and a variable set of the periphery of the system.
eriteria system includes:
- a set of sensors (contact, non-contact, remote)that has output parameters, built to severely limited parametric range;
device for measuring the influence of parameters of the environment;
- energy elements, the principle of operation of which is coordinated with the type of ammunition and energy parameters are determined by the needs of the system's core and peripherals;
device weekend Executive, providing direct control of the action of ammunition.
The core of the system is a processor that transforms the input touch devices, measuring devices influencing parameters of the external environment, the installed program functioning in the output controlling peripheral devices through the use of resource and energy elements.
Formatting data are exchanged between the system core and the periphery.
This approach allows for a limited set of peripheral devices due to their combination and use of various data processing programs to obtain the necessary diversity of species management action ammunition.
Should not be imposed significant restrictions on the design of peripheral devices, except those specified in the above.
