The invention discloses an automatic locking control system and method based on a stepping motor, and the automatic locking control system comprises a control panel and a locking mechanism. The locking mechanism comprises a position sensor, a stepping motor and a locking assembly connected with the stepping motor; the position sensor is used for converting the position information of the locking assembly into voltage information; the control panel is used for receiving a locking instruction sent by an external upper computer and generating a first driving signal according to the locking instruction; the first driving signal is used for driving the stepping motor to rotate so as to drive the locking assembly to operate in a direction close to the external swing mechanism until the real-timevoltage value acquired from the position sensor reaches a preset locking state threshold value; and according to the automatic locking control system and method based on the stepping motor, the position information of the locking mechanism is converted into voltage information through the position sensor, and whether the locking mechanism is locked in place is judged by acquiring the real-time voltage value of the position sensor, so that the control precision of the locking device can be improved, and the reliability of the system is enhanced.
Description
technical field [0001] The invention belongs to the technical field of automatic control and electric drive, and more specifically relates to an automatic locking control system and method based on a stepping motor. Background technique [0002] In some rotary mechanisms such as test automatic turntables, leveling mechanisms, and automatic rotation measuring instruments that are used daily, due to test requirements, it is necessary to lock the rotating shaft of the instrument, which is generally fixed by manual use of pins. But sometimes in order to meet the automation requirements in the test and measurement process, it is necessary to automatically lock the rotary shaft in the rotary mechanism. [0003] At present, the commonly used automatic locking methods include shaft-holding type, bolt type and electromagnetic clutch, etc. Among them, the bolt type uses a motor instead of manually pushing the bolt into the lock hole of the rotating part. The advantage of this method i...
