The invention provides a multipoint real-time parallel voltage measurement system based on wireless networking. The problem that an existing wireless voltage measuring device of a low-voltage transformer area cannot achieve multi-point real-time parallel measurement and mobile measurement of voltage is solved. The system comprises N mobile wiring clamps, N voltage measurement terminal modules anda voltage data collection coordinator. The measurement system is connected with a to-be-measured line through a mobile jointing clamp. Voltage is measured in a non-fixed wiring terminal access mode, the measurement mode is more flexible, the purpose of simultaneously and parallelly measuring the voltage of different to-be-measured line nodes in a low-voltage transformer area can be achieved, comparison between the voltage of the different to-be-measured line nodes in the same transformer area by workers is facilitated, and important reference suggestions are provided for transformation of a low-voltage rural power grid. In addition, the transmission of voltage data between the voltage measurement terminal module and the voltage data collection coordinator adopts a wireless communication mode, does not depend on the limitation of network bandwidth, and improves the precision and real-time performance of voltage measurement.
