A socket comprises a first housing, a plurality of conductive sheets and a first circuit module. The first housing is provided with a plurality of jacks. The conductive sheets are disposed inside the first housing and correspond to the first jacks respectively. At least two of the conductive sheets corresponding to the first jack side of the first housing are different in height. The first circuit module is accommodated and fixed inside the first housing and electrically connected with the conductive sheets. The conductive sheets are differently away from the corresponding first jacks, a common jack cannot be completely inserted onto the first jacks; the conductive sheets are connected with the conductive sheets corresponding to the plug, so that the common plug cannot be electrically connected with the socket, and an electric device connected with the common plug cannot be electrified. Therefore, other people cannot use the socket at will, and only the electric device with the plug matching with the socket can be fitly connected with the socket through the plug to be normally used.

The containing cavity used for containing the remote controller of the hoisting equipment is formed in the box body, the cover body is hinged to the upper end of the box body, the cover body can cover the upper end of the box body, locking management and control can be conducted on the cover body through the lock after the cover body is closed, the remote controller is prevented from being stolen, non-professionals are prevented from freely using the remote controller, and the remote controller is fixedly placed and is safe and reliable.

The present invention relates to the technical field of data collection, in particular to a user experience collection system and method for IPTV. The system includes a charging terminal and an IPTV network TV located on the top of the charging terminal. The charging terminal includes a control module, a display module, and multiple charging modules. and a plurality of button modules; the method includes S100, broadcasting advertisement information through the IPTV network TV located on the charging terminal in a place where the flow of people is concentrated; S200, when the charging terminal has a charging demand, the charging terminal displays the user experience information and obtains the filled-in information. Experience degree information. After obtaining the experience degree information, the charging terminal turns on the charging socket. The invention improves the probability of users viewing advertisement information and improves the accuracy of acquiring experience information.

The invention relates to a socket assembly, which comprises a socket and a plug. The socket comprises a first shell, a first circuit module and conducting strips. A plurality of arc-shaped first jacks are formed in the first shell. Circles where the first jacks are placed are concentric circles. The directions of the first jacks are the same. The first circuit module is arranged in the first shell. The conducting strips are arranged on the first circuit module corresponding to the first jacks and are electrically connected with the first circuit module. The plug comprises a second shell, a second circuit module and pins. A plurality of second jacks are formed in the second shell. The side surface of the second shell in which is second jacks are formed is butted with the side surface of the first shell in which the first jacks are formed. The second circuit module is arranged in the second shell. The number of the pins is multiple. Circles where the pins are placed are concentric circles. The directions of the pins are the same. The pins penetrate through the corresponding second jacks and are arranged on the second circuit module. The pins are arranged in the corresponding first jacks in a penetrating way, are butted with the conducting strips and are electrically connected with the conducting strips. The socket assembly can be prevented from being randomly used by other people.

The invention discloses an intelligent elevator safety management system and method. The system comprises user terminals and an elevator control system, wherein the user terminals are connected with the elevator control system through communication, and corresponding floor codes are configured to the user terminals. The elevator control system is provided with a car operation panel. Each user terminal is provided with an information input module and a fingerprint input module which are used for collecting identity information and fingerprint information of a user, and corresponding user information is generated according to the identity information and fingerprint information of the user and sent to the elevator control system. The car operation panel is provided with a plurality of fingerprint recognition modules, one floor code is allocated to each fingerprint recognition module, and fingerprint sensors are arranged. The fingerprint sensors are arranged on the surface of the car operation panel, and floor codes are marked. The elevator control system is arranged to transmit the user information received from the user terminals to the corresponding fingerprint recognition modules in the car operation panel according to the floor codes of the user terminals for storage. The intelligent elevator safety management system and method have the beneficial effect of being high in safety.
