| Abstract: | Introduces an intelligent apparatus, which realizes to protect motor by the tachometric survey. This apparatus takes the AT89S51 as a core, applies the hall switch and utilizes fully the inherent resources of single chip microcomputer system to realize fast the tachometric survey of motor each minute through the simple ef- fective survey algorithm. The appliance has excellent characteristics, such as the high reliability, the strong antijamming ability, the quick survey speed, the measuring accuracy, the simple circuit, the low cost, easy to install and ooerate and so on. |
