The invention discloses a verification method for orthogonal modulation data transmitted between a baseband unit and a radio frequency unit, including: 1. Module A obtains the IQ data verification value corresponding to each carrier, and verifies each carrier and its corresponding IQ data 2. Module B sends each received carrier and its corresponding IQ data check value to module C, and calculates the corresponding IQ data check value for each received carrier, and the same The calculated value of the IQ data check value corresponding to the carrier is compared with the received value to make a judgment on the transmission between module A and module B; 3. Module C calculates the corresponding IQ data check value for each received carrier , and compare the calculated value of the IQ data check value corresponding to the same carrier with the received value to make a judgment on the transmission between module B and module C. The technical scheme of the invention realizes online verification of all IQ data.

The invention discloses an intelligent examination room monitoring robot capable of human-computer interaction, comprising a human-computer interaction module. The human-computer interaction module is provided with a casing, and a non-complete gear driven and rotated by a power mechanism is connected with a fixed axis in the casing. The teeth on the incomplete gear are meshed with a transmission gear. The transmission gear is coaxially fixed with a driving wheel that rotates on the inner wall of the casing. The surface of the transmission gear is provided with an elliptical guide groove. A drive shaft is fixedly connected to the center of the circle, the inner wall of the casing is rotatably connected to a driven wheel that cooperates with the driving wheel, and the inner wall of the elliptical guide groove is slidably connected to a lifting arm. The present invention, through the cooperative use of the above-mentioned institutions, solves the problem that in the actual use process, in the highly tense environment of the examination room, the invigilator is prone to make mistakes, and at the same time, it also consumes a lot of manpower to supervise the examination, which brings inconvenience to the use. question.
