The model design of hardware voter

The voter, as the key component in either multi-model group system in the field of industry control or in the group decision support system, is the guarantee of efficiency of whole work and reliability. In the common situation, the voter can be realized by the pure-software. However, in the comparatives rigid industry-control field, especially in the group control or decision in distance under internet environment, the voter is easy to be interfered by the electromagnetism, even computer virus or hacker program and system has some degree of patient danger. On the other hand, in some situations of high requirement of responsible time, such as instant control system in the electronic net, prediction of short time charge in electronic system and adjustable decision system, software voter model is hard to meet the requirement of system velocity. Hardware voter, however, based on the hardware logic model, has much more advantage in the velocity and reliability than software one.
