Embodiment Construction

[0016] The ladder control system enters fingerprints through the fingerprint ladder control system. When the fingerprint acquisition unit 3 is abnormal, the CPU will switch to the fingerprint entry system, and the two ladder control systems will run alternately and are combined with the image ladder control system. In contrast, the ladder control information is entered only after the image similarity reaches the preset value, and the ladder control is diversified, effective and accurate.

[0017] The elevator control system in the present invention can also flexibly select the entry mode of the elevator control system according to the actual situation when installing and using the fingerprint acquisition unit, and when the fingerprint acquisition unit is in normal operation, it can send a prompt through the voice broadcast unit, which is convenient Used by elevator controllers.

[0018] The above descriptions are only preferred implementations of the present invention, and th...

Abstract

The invention provides an elevator control system identified by fingerprints. The elevator control system comprises a power supply, a power supply driving circuit, a fingerprint acquiring circuit, a SD card, a SD card interface circuit, a cortex A8 above ARM processor, an LCD display circuit, an LCD display screen, an audio output circuit and a horn; the power supply is connected with the cortex A8 above ARM processor through the power supply driving circuit; the fingerprint acquiring circuit is connected with the cortex A8 above ARM processor; the SD card is connected with the cortex A8 aboveARM processor through the SD card interface circuit; the cortex A8 above ARM processor transmits talkback visual information to the LCD display screen; audio prompts are sent out by the audio outputcircuit through the horn; the cortex A8 above ARM processor controls logic communication between fingerprint identification and circuits; and the cortex A8 above ARM processor is provided with a nearinfrared LED camera for visitors to perform fingerprint image extraction and digital processing.

Description

technical field [0001] The invention relates to a ladder control system using fingerprint identification, which belongs to the technical field of third-generation biometric identification. Background technique [0002] Elevators are more and more widely used in daily life. With the development of the aging population, some elevator cars are equipped with handicapped call control boxes for the disabled in addition to ordinary floor call control boxes. There are differences in some function settings between the ordinary floor call control box and the disabled call control box. For example, when there is a button call, the door opening and holding time of the disabled call control box is longer than that of the ordinary call control box. long. In addition, some cars with two doors (such as front door and rear door), there may be 4 or more control boxes inside the elevator car. [0003] In the existing technologies, most of them adopt card-type management, and more advanced on...
