| Abstract: | Overload limiter is an apparatus for hoists in operation with functions of automatic monitoring, alarm and power outage protection. Hardware and software design are introduced. The circuit of hardware includes the devices of load sensor and surveying instrument. The pressure signal is changed into electric signal by sensor. AT89c51 is the core of surveying instrument which is used to deal with data and judgment. Software design model is self-adaptive surveying system which can realize dynamic load filtering and zero correction. |
