| Abstract: | This paper presents a new auto inspection scheme of storage battery team voltage in ample power emergency power system. It adopts high density mounting type photocoupter (PT847) with a high isolation voltage between input and output. Combining with AT89C51 single-chip technique, main problems such as sampling from high voltage of storage battery to low voltage of control system, protection, auto-switching and itinerant testing are resolved appropriately in the circuit design. It achieves the function of automatic real-time inspection of storage battery voltage. Temperature compensation is applied effectively to restrain the influence of temperature on measurement precision. Test results demonstrate that the system has such advantages as fast inspection, high precision, intuitionist inspection results etc. |
