Abstract
The present invention proposes a kind of braking protection method of non balance weight antenna; increasing antenna braking protection module between the motor driver and motor of antenna, when antenna is powered normal, relay normally open contact is connected; motor driver is connected with motor; the driving moment of motor makes antenna normally work, and when disconnection powered by antenna, relay normally open contact disconnects; motor driver is disconnected with motor; relay normally-closed contact is connected simultaneously, and by armature winding short circuit, suppression antenna falls rapidly.Different from existing employing brake Method And Principle; the present invention uses simple switching circuit; antenna whereabouts drive motor own rotation is utilized to produce counter electromotive force; thus suppress antenna to fall rapidly; antenna therein braking protection module is made up of relay; circuit is simple and reliability is high, but also than existing brake method low cost.
Description
Technical field
The present invention relates to antenna servo and control technical field, be specially a kind of braking protection method of non balance weight antenna.
Background technology
The most common antenna system has orientation/pitching and X/Y mounting structures form.For orientation/pitching mounting, bow
Face upward axle and be typically easy trim, but X/Y mounting antenna trim is difficult to.For the mounting of non-trim, work as equipment
When powering up, due to the driving moment of motor, antenna can be maintained at a certain position；But when equipment lower electricity suddenly,
Motor power down, without output torque, due to action of gravity, antenna can fall rapidly, time serious, damages antenna structure；
Meanwhile, this is a kind of unsafe factor, dangerous to operator or neighbouring other staff's personal safety.
At present for the mounting of non-trim, it is typically employed on antenna axis increase brake method and solves sky during motor power down
The problem that line can fall rapidly.Antenna axis increases brake, when power was lost, brake action, makes antenna keep
Do not fall.But in this method, need to increase brake, relatively costly, and also brake is outside easily at antenna
By the environmental effects such as greasy dirt, hydraulic performance decline, fault rate is high.
Summary of the invention
Solve the technical problem that
For the antenna mount of solution trim by no means, during the unexpected power down of equipment, antenna can fall rapidly the equipment brought and personnel
Security protection problem, and conventionally employed brake method is relatively costly, and also brake is easily subject to outside antenna
The environmental effects such as greasy dirt, hydraulic performance decline, the problem that fault rate is high, the present invention proposes the system of a kind of non balance weight antenna
Dynamic guard method.
Technical scheme
The technical scheme is that
Described a kind of braking protection method of non balance weight antenna, it is characterised in that: at motor driver and the electricity of antenna
Increasing antenna braking protection module between machine, described antenna braking protection module is made up of relay；When antenna is just powered
Chang Shi, relay normally open contact connection, motor driver and motor connection, the driving moment of motor makes the normal work of antenna
Making, when disconnection powered by antenna, relay normally open contact disconnects, and motor driver is disconnected with motor, relay simultaneously
Device normally-closed contact is connected, and by armature winding short circuit, suppression antenna falls rapidly.
Beneficial effect
Different from existing employing brake Method And Principle, the present invention uses simple switching circuit, utilizes antenna to fall to carrying
Galvanic electricity machine own rotation produces counter electromotive force, thus suppresses antenna to fall rapidly, antenna therein braking protection module by
Relay forms, and circuit is simple and reliability is high, but also than existing brake method low cost.
Accompanying drawing explanation
Fig. 1: have the electrical connection of antenna braking protection circuit；
Fig. 2: antenna braking protection circuit module implementing circuit figure；
(a): wiring diagram between antenna braking protection circuit module and motor；
(b): wiring diagram between antenna braking protection circuit module and motor driver；
(c): antenna braking protection circuit module circuit diagram.
Detailed description of the invention
Antenna in the present embodiment has two kinematic axiss, X-axis and Y-axis, X-axis motor driver drive X-axis electricity
Machine, y-axis motor driver drives y-axis motor；Motor is five phase composite stepper motors.
Owing to this antenna uses the mounting of non-trim, when device power-on, owing to motor exports driving moment, antenna energy
Enough it is maintained at the position of requirement；But when equipment lower electricity suddenly, motor power down, without output torque, owing to gravity is made
With, antenna can fall rapidly, time serious, damages antenna structure；Meanwhile, this is a kind of unsafe factor, to operation
Personnel or neighbouring other staff's personal safety are dangerous.
So as it is shown in figure 1, the present embodiment increasing between the motor driver and motor of antenna antenna braking protection
Module, referring to the drawings 2, antenna braking protection module by one group of four relay form (be labeled as KX1, KX2, KY1,
KY2)；Antenna braking protection module one end is connected with motor driver DX, DY, such as Fig. 2 (b), the other end and stepping
Motor MX, MY are connected, such as Fig. 2 (a).
Antenna braking protection circuit modular circuit such as Fig. 2 (c), completes cutting of motor winding connection by the actuating of relay
Change.When antenna is powered normal, relay normally open contact is connected, and motor driver is connected with motor, the driving of motor
Moment makes antenna normally work；When disconnection powered by antenna, relay normally open contact disconnects, motor driver and motor
Disconnecting, relay normally-closed contact is connected simultaneously, by armature winding short circuit, after motor winding is received together, by
Disconnecting with motor in motor driver, antenna can be fallen by action of gravity, and drive motor rotates, so that motor produces
Raw counter electromotive force, stops antenna structure to continue falling motion.By such process, it is achieved the power down protection of antenna.
