The invention discloses a method for locking and unlocking a display screen. The method includes the following steps: when the display screen is in a power-off state, receiving a key operation corresponding to the display screen; if the key operation is a target key operation , then in response to the target button operation, the display screen enters the pre-unlock mode, and when the display screen is in the pre-unlock mode, the status information of the display screen is confirmed; if the status information is confirmed according to the status information If the display screen is in a screen-locked state, the display screen is controlled to enter a screen-locking and unlocking mode, and a screen-locking and unlocking operation is performed on the display screen. The invention also discloses a display terminal and a readable storage medium. The pre-unlocking mode can be started by simple button operation, and when the display screen is in the screen-locked state, the screen-locking and unlocking operation can be performed independently, which improves the convenience of screen-locking and unlocking of the organic light-emitting diode display screen.

The invention discloses a quick release for a current-limiting circuit breaker, which includes a casing, a drive system, a lock, a pull rod, a lock shaft, a lock torsion spring, a pin shaft and screws, and the drive system is fixed inside the casing through screws. The pin shaft and the lock shaft are fixedly installed in the shell, the lock is installed on the lock shaft, the lock torsion spring is installed on the lock shaft and the pin shaft, and provides rotation force for the lock, and the pull rod is installed on the shell through the guide boss It is connected to the lock hinge through the pull rod boss on the pull rod. Driven by the lock, it can move in a straight line and drive the tripping shaft of the circuit breaker to realize opening. The patent of the invention adopts the piezoelectric stack as the power source, which has fast response, can realize tripping and opening in time, improves the current limiting level of the current-limiting circuit breaker, prevents the contacts from falling back and welding after being repelled, and enhances the breaking of the circuit breaker Capability; use the triangular amplification principle to directly amplify the micro-displacement of the piezoelectric stack to an appropriate multiple, without the need for an intermediate conversion mechanism, small size, and compact structure.

The invention discloses a calibration method and device for receiving signal strength, which receives a detection signal transmitted by a calibration signal transmitting coil; the detection signal includes the first distance between a low-frequency signal receiving entity and the calibration signal transmitting coil, and the first drive of the calibration signal transmitting coil current and the first low-frequency signal; measure the first low-frequency signal to obtain the first actual received signal strength; query the preset calibration table according to the first distance and the first driving current to obtain the first field strength compensation value; according to the first field strength compensation The value is calibrated to the first actual received signal strength to obtain the calibrated first actual received signal strength. The present invention calibrates the first actual received signal strength by pre-establishing a calibration table, and realizes accurate positioning according to the calibrated first actual received signal strength. For example, when applied to the PEPS system, the vehicle can calculate the low-frequency signal received The exact distance between the entity and the vehicle it belongs to, unlocking the door in time.

The invention discloses an electronic system for an ATM (automated teller machine) protection cabin door and an implementing method of the electronic system. The electronic system is characterized in that a cabin door controller unit is connected with a human body sensor, an acoustic input circuit and an acoustic output circuit, wherein the sensitivity of the human body sensor is controlled by a mode I and a mode II of the human body sensor; a microphone of the acoustic input circuit is arranged in a cabin, and a loudspeaker of the acoustic output circuit is arranged outside the cabin; the height of detection space away from the ground in the cabin when the human body sensor is in the mode I is smaller than that of the detection space away from the ground in the cabin when the human body sensor is in the mode II, and a step is arranged in front of an ATM. According to the method, during a period that an entry button unlocking function keeps shielded, the human body sensor working in the mode I and the mode II alternately performs following settings: the condition that a child gets trapped is determined and unlocking is performed when the following conditions are met: (1) the condition that duration when an input acoustic signal amplitude with the interval smaller than a set value is larger than a set threshold value reaches a specified value is detected and recognized; (2) during the duration, the condition that nobody faints and falls to the ground is determined, and the cumulative time when a human body is detected by the human body sensor in the mode II accounts for lower than 30% of the total working time of the sensor in the mode II.

The present disclosure relates to a wheelchair lift and a method and a vehicle applied to the wheelchair lift. The wheelchair lift includes a lifting platform, abutting parts and a driving mechanism. Two space-limiting long grooves are oppositely arranged on the upper surface of the lifting platform, and the two space-limiting long grooves are respectively used to accommodate two space-limiting wheelchairs. Wheelchair wheels, the drive mechanism can drive the abutting member to move in the long space-limiting groove in the vertical direction, so that the wheels of the wheelchair can withdraw from the long space-limiting groove, and the lifting platform is also provided with There is an inclined surface for the wheelchair to enter and exit the lifting platform, and the inclined surface extends obliquely downward from the upper surface. By setting the long limit slot, the wheelchair can be locked to prevent the wheelchair from shifting during the lifting process, and the safety is high. Moreover, by providing the abutting member and the driving mechanism, the wheelchair can be unlocked in a timely and convenient manner after the lifting platform is raised and lowered to a certain position, and an inclined surface is provided to facilitate the removal of the wheelchair from the lifting platform, which improves convenience.
