The invention discloses a pet positioning device and a socializing method thereof. The method includes a housing body, hardware and a mobile control end cooperating therewith. The hardware includes apower supply module, a signal receiving module, a central processor registration management module, a GPS transmitting module, a start switch and an LED light. The power supply module, the signal receiving module, the central processor registration management module and the transmitting module are all disposed inside the housing body, and are mutually connected through electric wires. The start switch and the LED light are disposed on the housing body. The power supply module provides required power for the pet positioning device, the signal receiving module receives signals of an SIM card, and a central processor processes the received signals, carries out signal and position conversion calculation, and simultaneously issues an instruction to the LED light to illuminate the correspondingLED light. By employing the pet positioning device and the socializing method thereof, the pet positioning device is enabled to carry out precise positioning and distance measurement; a position wherea target is located can be accurately known; and a more direct and effective method is provided for pet socializing.

The invention relates to the field of a wiring switch, and discloses a rotary switch. When a gear needs to be rotated, a rotary shaft is only required to be rotated; the rotary shaft drives a movable contact piece, which is arranged on the rotary shaft in a sleeving manner, to rotate; a rotary positioning apparatus is used for positioning the rotation of the rotary shaft and the movable contact piece; a rotary contact is in contact with a corresponding rotary contact piece on a chassis successively so as to realize electric connection and gear regulation; when inching control is needed, an inching contact is only required to be rotated to an inching contact piece; then inching electric connection between the inching contact and the inching contact piece is realized by pressing the rotary shaft; and therefore, the rotary switch is simple in wiring, less in components, and high in electric appliance safety.

The present invention relates to the field of a wiring switch, and discloses a motor rotary switch. When shifts are needed to rotate, a rotary shaft is rotated to drive a moving contact piece sleeving the rotary shaft. A rotary positioning device positions the rotation of the rotary shaft and the moving contact piece. A rotary contact is successively touched with rotary contact pieces on a base plate, and thus the electric connection and the shift adjustment are realized. When the point control is needed to be performed, a point moving contact is only needed to be rotated a point moving contact pieces, and then the point electric connection of the point moving contact and the point moving contact pieces is realized by pressing the rotary shaft. A micro-moving contact point on a micro-moving switch is pressed by pressing the rotary shaft, and the micro-moving switch is touched to carry out motions. The motor rotary switch has simple wirings, few elements, and high electric appliance safety.

A balanced bridge comprises an input signal source, a reference impedance, an impedance to be tested, a bridge balancing module and a balance control module. The reference impedance is serially connected with the impedance to be tested and connected with the input signal source and is used for obtaining current vectors. The bridge balancing module comprises a reference impedance current extraction unit and an impedance to be tested current extraction unit and is used for providing bridge output pressure for the balance control module. The reference impedance current extraction unit is coupled to two ends of the reference impedance, the impedance to be tested current extraction unit is coupled to two ends of the impedance to be tested, and an output port of the bridge balancing module is an output port of bridge output pressure. The balance control module comprises a pressure detection module, a feedback circuit module and a single chip microcomputer, wherein one end of the pressure detection module is connected with the output port of bridge output pressure, the other end of the pressure detection module is connected with the single chip microcomputer, the other end of the single chip microcomputer is connected with the feedback circuit module, and the feedback circuit module is coupled to the impedance to be tested current extraction unit.
