Abstract
The utility model relates to a current-controlled lodging mechanism control system used for controlling folding and unfolding of an antenna part in a military or civilian communication vehicle. The system comprises a motor used for driving a lodging mechanism to motion through forward rotation and backward rotation and a motor driving circuit capable of driving the motor to forwards rotate and backwards rotate. The output end of the driving circuit is connected with a current sensing resistor in series. The voltage signal of the input end of the current sensing resistor is connected to a control module through an amplifying circuit. The control module is capable of controlling power on-off of the motor driving circuit. The control system determines whether the antenna is in place by detecting current change of the motor driving circuit in running process in order to achieve a stable antenna platform without gaps and prevent shaking of the antenna. A large number of travel switches are not required to be arranged in the current-controlled lodging mechanism control system with simple circuit structure and high reliability.
Description
Technical field
The utility model relates to a kind of current-control type lodging mechanism control system for the folding and unfolding of military or civilian communication automobile antenna element is controlled.
Background technology
Existing most onboard wireless communication devices need column or the whip antenna of the large and need vertical operation of car outside supporting height dimension, but consider the requirement of vehicle highway limit for height, during Vehicle Driving Cycle, need the antenna lodging is placed on compartment or pilothouse top, this just needs to install a cover lodging mechanism.The built-in reducing motor of lodging mechanism, the general simple circuit control mode that adopts travel switch to add relay, adopt this control mode, the antenna rear triggering travel switch that puts in place, motor namely cuts off the power supply, because there is angular clearances naturally in the worm-gear speed reducer output terminal, cause having necessarily under the vertical state of antenna and rock, normal operation has certain influence to communication apparatus, and the travel switch circuit-line is complicated, system reliability is low, and failure rate is higher.
Summary of the invention
Technical problem to be solved in the utility model is that the antenna that provides a kind of gap of eliminating drive disk assembly to cause rocks, and the current-control type that circuit structure is simple, reliability is high lodging mechanism control system.
Current-control type of the present utility model lodging mechanism control system includes one by rotating and reverse the motor that drives the lodging mechanism action, but also includes the motor-drive circuit that drive motor rotates and reverse; The output terminal of described driving circuit is serially connected with the inspection leakage resistance, and the voltage signal of inspection leakage resistance input end is through amplifying circuit Access Control module, and control module can be controlled the switching of motor-drive circuit.
Pass through to detect the curent change of motor-drive circuit in the utility model course of work, whether antenna put in place judge, its principle is: after antenna platform arrives the vertical operation position, mechanical stop limiter stops antenna platform and motor rotation, " stall " state appears in motor, its internal current increases at once, when current value arrives the setting value of control module, control module is cut off power supply immediately, this moment, whole gear train was in " chucking " state, antenna platform is stablized gapless, has avoided antenna to rock; The utility model need not to arrange a large amount of travel switches, and circuit structure is simple, reliability is high.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Embodiment
As shown in Figure 1, this current-control type lodging mechanism control system includes one by rotating and reverse the motor M that drives the lodging mechanism action, but also includes the motor-drive circuit that drive motor rotates and reverse; The output terminal of driving circuit is serially connected with inspection leakage resistance 1, and the voltage signal sampling point A of inspection leakage resistance input end is through control module 3 of an amplifying circuit 2 accesses, and control module can be controlled the switching of motor-drive circuit.
The driving circuit of motor M described in the illustrated embodiment includes the full-bridge circuit that is made of triode Q1, Q2, Q3, Q4, the rotating band dead band function of full-bridge circuit, and conducting causes large electric current to damage circuit when preventing Q1, Q2 or Q3, Q4.Full bridge driving circuit can be controlled by the duty cycle of switching that Q1～Q4 is controlled in pulse-length modulation the electric current of motor in addition, and then the rotating speed of control motor.Usually when running well 3～10 times of the electric current of motor when stall, lodging mechanism rise put in place and lodge put in place after since the effect motor of mechanical position limitation with stall, just can detect and lodge whether open and close put in place in mechanism by detecting current of electric.To ground, the voltage that A is ordered on the inspection leakage resistance has embodied the electric current of motor to the electric current of full-bridge circuit as shown in Figure 1 by the inspection leakage resistance, and the larger A point voltage of electric current is higher.Usually all smaller for reducing the impact inspection leakage resistance of circuit, the level that A is ordered is usually lower, needs could be used by control module through behind the amplifying circuit.Control module Real-Time Monitoring circuital current, when find that current continuity a period of time increases suddenly or think when surpassing limit value lodging mechanism switch put in place, control circuit cuts out full-bridge circuit.
