Technical field
The utility model relates to a kind of Radar Servo control system.
Background technology
The stepping motor servo-control system of weather radar, the rotation mode that tradition Radar Servo rotation field adopts is servo control system, comprehensive radar antenna with 360 °, control radar orientation, 90 ° of pitching rotates, this system control realizes single, but this servo control system use cost and costliness thereof, and bulky etc., for some low-cost miniaturization radar systems, be undoubtedly the use bottleneck of.
The utility model content
For above-mentioned deficiency, the purpose of this utility model is to provide the low Radar Servo control system of the high and production cost of a kind of control motor precision.
The technical solution of the utility model is achieved in that a kind of Radar Servo control system, comprise and control servo card, driver, stepping motor, host computer, described control servo card is connected with stepping motor by driver, described control servo card is connected with host computer, and described control servo card is provided with the FPGA data processing module.
Further, described host computer is connected with control code check module and demonstration corner brace module respectively.
Further, on described control servo card, also be provided with network control module, be connected with on this network control module and generate the corner brace module.
Further, between described network control module and host computer, by the RJ-45 interface, be connected.
Compared with prior art, the beneficial effects of the utility model are: after adopting said structure, with general servo system, compare, the SERVO CONTROL action of stepping motor can meet the needs of normal radar fully, reliability is high, can realize that the speed of stepping motor is adjustable by changing FPGA data processing module inner parameter, control motor speed and the precision space that has greatly improved, production cost is decrease also.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment technical scheme, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only that this practicality is in order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
