Abstract: A temperature measuring circuit, measuring apparatus and a measuring method thereof relating to the field of electronic circuits. The temperature measuring circuit includes control unit, wherein the control unit includes a first current output interface, a second current output interface, a first input/output interface, a second input/output interface, and a third input/output interface. Further, the first current output interface and the first input/output interface of the control unit are respectively electrically connected to a first interface of a temperature sensor; the second current output interface and the second input/output interface of the control unit are respectively electrically connected to a second interface of the temperature sensor; and the third input/output interface of the control unit is electrically connected to a third interface of the temperature sensor.

Abstract: An equipment unit state controlling method and device, and an equipment unit. After receiving control data transmitted from a state controller, a unit controller detects whether the unit controller communicates with a display panel controller, in which the state controller transmits the control data to the unit controller and the display panel controller simultaneously. If the unit controller communicates with the display panel controller, the unit controller performs an operation on the equipment unit corresponding to instruction information transmitted from the display panel controller, and if the unit controller does not communicate with the display panel controller, the unit controller parses the control data by itself to obtain the parsing result and performs the operation on the equipment unit corresponding to the parsing result.

Abstract: Systems and methods for controlling a locking device over a short-range wireless radio frequency. The system comprises an intelligent user terminal and a locking device, and authorizes access based at least upon information received at a user interface of the locking device and authorization data transmitted to the locking device by the intelligent user terminal. The methods comprise receiving an access request at a locking device, configuring the locking device to establish a connection to the intelligent user terminal, establishing the connection, and authorizing the intelligent user terminal based on authorization data.
