Flow field measuring device and flow field measuring system

The embodiment of the invention provides a flow field measurement device and a flow field measurement system, and the device comprises an acquisition module which is used for sensing to-be-collected information in a flow field, and converting the sensed to-be-collected information into an electric signal; and a wireless transmitting module which comprises a wireless data transmitting module, a single chip microcomputer and an antenna system, wherein the wireless data transmitting module is connected with the acquisition module to obtain an electric signal and transmit the electric signal to the antenna system, the single-chip microcomputer is connected with the antenna system so as to control the antenna system to establish point-to-point data transmission connection with the target device, and the antenna system sends an electrical signal to the target device. Therefore, wireless transmission from the acquisition module to the target equipment is realized, a line between the flow field measurement device and
