Virtual Instrument Technology for Elevator Safety Monitoring and Alarm System

Recently, with the increase of high-rise buildings, as a convenient tool, elevator has become more and more popular. However, the cost of safety monitoring equipment is relatively high in the elevator market, and is not suitable for the promotion of small and medium-sized elevator use. This paper makes use of virtual instrument technology to monitor the operation state of elevator. Labview visual module has a large of specialized controls and function libraries, with cameras. It can monitor and warn the elevator running state efficiently and accurately. In addition, the system is easy to modify, can add some other common elevator conditions, such as calculating the number of passengers, face recognition and so on. The system will be more perfect by increasing functional models.
