Description
Technical field
The invention belongs to parking lot banister technical fields, more particularly to a kind of frequency conversion barrier equipment based on DDS.
Background technology
As the improvement of people's living standards, automobile enters huge numbers of families.Especially in recent years, develop more rapid.
Traffic congestion, vehicle exhaust, parking difficulty are at metropolitan pain.Automobile is passing through parking lot entrance and turn pike bayonet
When, traditional banister at a slow speed cannot meet the needs of people are to traffic efficiency.Traditional banister speed is slow, ETC, remote
The efficient performance of the advanced toll collection system such as Card Reader, Car license recognition can not be played effectively, more cause the safety problems such as lance.Tradition
After banister improves speed by force, due to mechanical structure problem, easily cause that low, serious, short life of fever of transmission efficiency etc. is a variety of to ask
Topic.
Invention content
To be solved by this invention is that traditional banister speed is slow, the nonadjustable problem of speed, provides a kind of change based on DDS
Channel brake apparatus, to solve the above problems, the present invention is achieved by the following technical solutions.
A kind of frequency conversion barrier equipment based on DDS, the frequency conversion barrier equipment are sensed by man-machine input module, position and speed
Device, STM32 controllers, DDS frequency-variable modules, three-phase inverter and three phase alternating current motor composition.Man-machine input module, position and speed
Sensor is unidirectionally connect with STM32 controllers, and STM32 controllers are unidirectionally connect with DDS frequency-variable modules.DDS frequency-variable modules export
Direct current be transported to three-phase inverter, be converted into three-phase alternating current, for drive three phase alternating current motor rotating forward and hair turn；People
Machine input module is used for being arranged the time that the banister rod of frequency conversion banister rises and falls, angle banister rod rise and fallen.Position
Set the real-time angular that velocity sensor is used for monitoring the real-time rotating speed and banister rod of three phase alternating current motor.
Compared with prior art, good human-computer interaction interface and microcontroller high speed data processing and position and speed pass
Sensor detects in real time, has the characteristics that the lifting time of banister rod is controllable, lifting angle is adjustable.
