The utility model provides an antenna erects control system, includes the controller, and control system adopts the PCC controller, and host computer, touch-sensitive screen or panel button issue the instruction to the controller, and the controller receives control signal, angle encoder's angle data, integration servo motor information, position calibration proximity switch and upper and lower limit proximity switch's information and handles, and output control command carries out corresponding action to upload host computer, panel pilot lamp and touch-sensitive screen display with the system state.
The upper and lower limit proximity switches and the position calibration proximity switch information are directly connected into the integrated servo motor, the upper and lower limit proximity switches are used for electrical limit protection of the electric cylinder, and the control system collects position calibration proximity switch signals to serve as the basis of position calibration.
And the data information of the high-precision angle encoder is accessed into the controller through the CAN bus, and the PCC controller calculates the current angle value of the antenna and carries out filtering processing.
And the position information, the current information and the data of the angle encoder which are fed back to the controller by the integrated servo motor are used as the input information of control software to participate in the control flow of the erecting system.
The controller is communicated with the touch screen and the upper computer and uploads the current state information of the system to the touch screen and the upper computer for display. Both the touch screen and the upper computer can issue instructions to the controller to execute corresponding actions.
The controller sends the current state information of the antenna erecting system to the panel indicator light through the digital quantity output module, and different changes of the indicator light display different states of the antenna erecting system.
The controller is communicated with the touch screen and uploads the action process of turning the antenna up and down to the touch screen for dynamic real-time display.
The controller is characterized in that a control software is designed with a erecting control algorithm, wherein the erecting control algorithm comprises an antenna shaking elimination function, and shaking of the antenna in the erecting process is avoided.
Install on the antenna base and play electronic jar of erecting, integrated servo motor installs on playing electronic jar of erecting, and base trunnion department installs high accuracy angle encoder. The controller receives antenna angle information, vertical electric cylinder state information, position calibration proximity switch B3, calibration proximity switch A2, upper limit proximity switch 4 and lower limit proximity switch 1 state information in real time. And after receiving the feedback information and processing the feedback information by an algorithm, filtering and the like, control software of the controller judges the current state of the antenna, and determines the action of the erecting electric cylinder according to the state of the erecting electric cylinder fed back by the integrated servo motor. The purpose of designing the position calibration proximity switch is to correct the position information of the vertical electric cylinder, when a position calibration proximity switch signal is received, the current position of the vertical electric cylinder is judged to be consistent with the fed back data, and if the current position of the vertical electric cylinder is not consistent with the fed back data, the fed back position information of the vertical electric cylinder is updated; the upper limit proximity switch and the lower limit proximity switch are used for electrical limit protection of the travel of the supporting leg, and when the signal of the upper limit proximity switch 4 is received, the vertical electric cylinder only can do retraction action and can not do extension action any more; after receiving the signal of the lower limit proximity switch 1, the vertical electric cylinder only can do stretching action and can not do retracting action. And state information in the erecting process is uploaded to an upper computer, a panel indicating lamp and a touch screen in real time for display.
