The emotional state change trend of the cloud server can be accurately collected and displayed, the emotional change of the user is purposefully guided, and the effective guide of the emotional of the actor is realized.

The invention discloses a SIM card and its anti-cloning method and device. The main content includes: using the clock signal provided by an external clock to record the cycle value, and according to the recorded cycle value, the data received in the cycle that needs to be compared The number of authentication requests of the SIM card is compared with the threshold, and after the comparison result satisfies the card locking condition, the SIM card is locked. Since the threshold can be flexibly set according to actual experience, the legitimacy of the authentication can be judged according to the number of authentications received in the period that needs to be compared, thereby ensuring that the attacker cannot obtain valid authentication data in a short period of time , improving the security of the SIM card.

The embodiment of the invention provides a driving distance correction method and device, belonging to the technical field of car accessories. The driving distance correction device comprises image collectors, an image processor, a central controller, a memory and a display. The image collectors are used for collecting image information of obstacles around a car, and sending the image information of the obstacles to the image processor; the image processor is used for synthesizing the image information of the obstacles and reference image information pre-stored in the memory so as to obtain corrected image information, and sending the corrected image information to the central controller; and the central controller is used for controlling the display to display the corrected image information. The reference image information comprises image information that is acquired by the image collectors for use as a distortion reference when a plurality of reference objects are arranged around the car. The invention effectively reduces implementation costs, and increases the accuracy with which drivers can judge changes in distance.

The invention relates to the field of communication, in particular to a method for accessing a mobile phone to a cloud video conference system, which comprises the following steps of: S1, connecting a cloud video conference system terminal with a conference system in the mobile phone; s2, registering a mobile terminal of the cloud video conference system in a server through a protocol, and calling the mobile terminal by the server to realize the access of the mobile terminal to the equipment; s3, when a conference link is generated and sent to the participants, the central control module carries out secondary detection on the sound definition; and S4, when the central control module completes the judgment of the access of the host, the central control module judges whether to carry out noise reduction adjustment on the conference noise according to the type of the sound receiving equipment used by the conference participants, and when the central control module completes the adjustment of the conference system parameters, the central control module carries out noise reduction adjustment on the conference system parameters. And the central control module controls the conference system to carry out formal start operation on the accessed cloud video conference. According to the invention, the accuracy and effectiveness of accessing the mobile phone to the cloud video system are improved.
