The invention relates to an intelligent instrument based on the IOT (
Internet of Things), and the instrument comprises a housing, a display interface disposed on the housing, a status indication interface, a voice
alarm device, a work power supply button and an
information storage interface, wherein the display interface, the status indication interface, the voice
alarm device, the work power supply button and the
information storage interface are disposed on the housing. The interior of the housing is provided with a central control device, and the central control device is a PLC. The display interface, the status indication interface, the voice
alarm device, the work power supply button and the
information storage interface are respectively in
electrical connection with the central control device. The instrument provided by the invention carries out
remote communication with a background terminal through a
wireless communication module, guarantees that a worker carries out the real-time monitoring of the instrument, and improves the practicality of the instrument. The rotation of a drive gear is controlled through a
drive shaft, and four driven gears are driven to rotate at the same time. A guide sliding block is controlled to push a fixed rod out, thereby achieving the fixing of the instrument on a power distribution cabinet. Moreover, in a voice alarm circuit, a
diode is used for absorbing a backward
voltage generated by a
buzzer in a switching process, thereby improving the reliability of the instrument.
