The invention discloses a prototype display method. According to the method, the characteristic that a current intelligent terminal is generally provided with a distance sensor and a face recognition function is utilized; when the prototype judges that no person is in the set range, the screen can be automatically turned off, so that the invalid working time of the prototype is reduced, and the service life of the prototype is prolonged; when someone exists, the gender and age characteristics of the current customer can be recognized through the face recognition function, proper advertisement film resources are played, and the publicity effect is improved. Besides, when it is judged that a new customer appears according to the facial features recognized by the human face, the prototype automatically clears all use traces of the previous customer, and the prototype use experience of each customer is improved.

The invention discloses a sewing machine thread cutting mechanism which comprises a right thread cutting drive rod, a left thread cutting drive rod, a left thread cutting drive cylinder and a switching switch. The right thread cutting drive rod is used for driving a right movable cutter shaft to rotate, the left thread cutting drive rod is used for driving a left movable cutter shaft to rotate, two ends of the left thread cutting drive cylinder are hinged to the right thread cutting drive rod and the left thread cutting drive rod, and the switching switch is used for switching contacting states between a piston rod of the left thread cutting drive cylinder and a cylinder barrel. The switching switch is adjusted, the piston rod and the cylinder barrel are relatively fixed, the right threadcutting drive rod drives the left thread cutting drive rod to synchronously act, double sewing threads are cut off, the switching switch is adjusted again, the piston rod and the cylinder barrel are relatively slide, right thread cutting drive rod drives the cylinder barrel to slide relative to the piston rod, the right thread cutting drive rod separately acts relative to the left thread cutting drive rod, and a single sewing thread is cut off. When the right thread cutting drive rod acts, the left thread cutting drive rod can be static, and falling-off of the sewing thread is effectively prevented, so that working reliability is improved. The invention further discloses a sewing machine with the sewing machine thread cutting mechanism.

The invention relates to the technical field of networks for monitoring a spatial dynamic element, in particular to a multi-network cooperative work method for monitoring the spatial dynamic element. The method comprises the following steps that a plurality of wireless sensor networks are sequentially arranged on the moving path of the dynamic element; a server serves as a center of a whole monitoring system; the server carries out analysis and judgment on information collected by the wireless sensor networks, and assigns tasks or sleep instructions to the wireless sensor networks, and the monitoring task is completed in a relay mode. According to the multi-network cooperative work method for monitoring the spatial dynamic element, due to the facts that the wireless sensor networks sequentially carry out monitoring work according to the position of the monitored element, and the whole monitoring task is completed in the relay mode, the ineffective working time of each network is greatly reduced, resource utilization efficiency is improved, and the service life of the networks is prolonged.

The invention discloses a device for removing siloxane in biomass gas, which includes a refrigeration cycle unit, a refrigerant cycle unit and a biomass gas siloxane removal unit; a cold storage tank is provided for cold storage of the refrigerant, and two The heat exchanger for removing siloxane works alternately, and the incoming biomass gas is precooled by the refrigerant after heat exchange with the biomass gas and the biomass gas after removing siloxane. The invention can adapt to different working conditions, and is suitable for removing siloxane gases in biomass gas in actual operation, so as to ensure efficient application of biomass gas.

The invention discloses an anti-deviating energy-saving type microwave vulcanization device achieving stable vulcanization and a using method thereof. The anti-deviating energy-saving type microwave vulcanization device achieving stable vulcanization comprises a support which is provided with a conveying belt, vulcanization tanks are arranged above the conveying belt, a dehumidification device is arranged above each vulcanization tank, a master control device is arranged at the head end of the conveying belt, and a power device is arranged at the tail end of the conveying belt. The master control device comprises a driven shaft, a deviation rectifying device is arranged beside the driven shaft, and an encoder is arranged on the driven shaft. A driving shaft is connected with the driven shaft through the conveying belt. A material sensor is further arranged at the head end of the conveying belt. Magnetrons are distributed in the vulcanization tanks, and temperature sensors are arranged between the magnetrons. Spray nozzles are further arranged above the magnetrons. The deviation rectifying device comprises a deviation rectifying motor which is connected with a sliding block, the sliding block is connected with an adjusting roller, and travel switches are further arranged on the two sides of the conveying belt correspondingly. The anti-deviating energy-saving type microwave vulcanization device achieving stable vulcanization and the using method thereof have the characteristics that energy consumption is reduced, the service life is prolonged, the equipment utilization rate is increased, and transportation is stable.
