The invention discloses a safety distribution board monitored based on the wireless sensor technology. The safety distribution board comprises a power supply distributor and three power distributors. Each power distributor is composed of an electric control circuit, a frequency conversion controller, a pumping unit intelligent intermittent pumping controller, a wireless sensor module, a data acquisition module, a figure testing sensor, a digital pressure sensor, a digital temperature sensor and a three-phase power acquisition module. The wireless sensor module includes an ARM microprocessor and a remote monitoring center. The ARM microprocessor is connected to a GPRS module through an RS232 interface, and the GPRS module is connected to the remote monitoring center via a GPRS network. The e ARM microprocessor is connected to an Ethernet gateway through an Ethernet interface, and the Ethernet gateway is connected to the remote monitoring center via the Internet. According to the invention, data acquisition is reliable, analysis of the working condition is accurate, frequency adjustment is scientific, and field application is stable. Energy saving is achieved, and the efficiency of the pumping system is improved. Moreover, wireless remote monitoring is realized, and the safety of underground work is ensured.
