Portable elevator safety performance monitoring system based on CAN bus

The invention discloses a portable elevator safety performance monitoring system based on a CAN bus. The system comprises an acceleration detection module, a noise detection module, a power detection module, a man-machine interaction module, an MCU master control module, a gateway module, a power supply module and other parts, wherein all the functional modules are provided with CAN bus interfaces; through CAN bus configuration, the functional modules can be configured according to the requirement of a field test and realize plug and play, and the structure of the detection system is more reliable and flexible; a CAN communication protocol is set up, and detection results are encrypted with MD5, so that the authenticity and traceability of information are ensured; and a remote server can supervise schedules of maintenance personnel and allocate tasks in real time, and thus is conductive to quickening the elevator detection process and improving the efficiency.
