The invention provides torrential flood debris flow tap flow velocity electromagnetic wave monitoring equipment and a torrential flood debris flow tap flow velocity electromagnetic wave monitoring system. The equipment comprises an electromagnetic wave velocity measurement probe, an analog-digital conversion module, an external clock, a main control module, a monitoring data processing module and a Zigbee module, wherein the electromagnetic wave velocity measurement probe is used for sending collected electromagnetic wave signals; the analog-digital conversion module is used for conducting analog-digital conversion on received electromagnetic wave signals to form digital signals and sending the digital signals; the external clock is used for providing time information for the main control module; the main control module is used for integrating received digital signals and acquired time information and then sending the received digital signals and the acquired time information to the monitoring data processing module; the monitoring data processing module is used for sending integrated data to the Zigbee module; and the Zigbee module is used for uploading the integrated data through a Zigbee network. The torrential flood debris flow tap flow velocity electromagnetic wave monitoring equipment and the torrential flood debris flow tap flow velocity electromagnetic wave monitoring system can monitor a situation that whether a torrential flood debris flow happens or not, measure the torrential flood debris flow tap flow velocity in real time and send the data to a data receiving terminal without being affected by the external environment, are low in mounting accuracy requirement and networking cost, and are not limited by mobile communication networks, the volume of a short message server and the volume of a terminal subscriber identity module (SIM) cards.
