Abstract

The invention provides a Bluetooth communication control circuit of an electric actuating mechanism, comprising a DC-DC power supply conversion circuit, a master control CPU unit circuit, a serial port level conversion circuit, a Bluetooth emitting and receiving module and a driving signal circuit thereof; wherein the DC-DC power supply conversion circuit uses a switching power supply chip and a low-dropout linear regulator chip, the switching power supply chip is connected with an inductance coil through a voltage output end to supply power for the serial port conversion circuit and the master control CPU unit circuit, and a voltage output end of the low-dropout linear regulator chip is connected with power supply input ends of the Bluetooth emitting and receiving module and the driving signal circuit thereof; and the Bluetooth emitting and receiving module and the driving signal circuit thereof converse level by a level conversion chip to implement communication with a CPU unit. In the Bluetooth communication control circuit of the electric actuating mechanism, with a Bluetooth module added in an SND product and connected with an external CPU, the short-distance wireless programming and the diagnosis for the SND product are implemented, and the Bluetooth communication control circuit can be generalized and used in large scale.

Description

technical field [0001] The invention relates to a bluetooth communication control circuit of an electric actuator. Background technique [0002] With the development of modern industry, SND series electric actuators, as industry-leading products, are widely used in electric power, metallurgy, petrochemical and water treatment industries, and are actually used in a wide area, and some are even exported. However, it is extremely cumbersome to diagnose and deal with problems with SND products at present, and how to perform short-distance wireless programming and diagnosis on them also needs to be solved. Contents of the invention [0003] In order to solve the above problems, the present invention provides a bluetooth communication control circuit of an electric actuator, which can perform short-distance wireless programming and diagnosis on SND products, that is, bluetooth communication control. [0004] In order to achieve the above object, the technical solution adopted i...
