A kind of network built-in type robot controller
Technical field
The present invention relates to a kind of network built-in type robot controller.
Background technology
In the industrial robot, modal is manipulator and revolute robot at present.The intelligent robot motion control as shown in Figure 1, had both comprised and had controlled required various hardware systems, comprised again various software systems.Hardware system comprise host computer, slave computer (or), servo-driver, software systems comprise upper computer software, slave computer software.After the robot hardware system finishes, purposes difference according to robot is carried out functional programming to robot, the robot program who finishes is deposited among the EPROM of slave computer (or PLC), by slave computer the robot servo-driver is controlled, robot body is moved by functional requirement.Slave computer and upper machine communication are realized human-computer dialogue, and host computer is served as by ordinary PC or the special-purpose PC that touches.The shortcoming of above control technology: complex structure, the trouble point is many; The a large amount of open loop controls of control system, potential safety hazard is many; The robot control program is strongly professional, require height to controlling personnel, and tool program specificity is strong, is difficult to realize generalization; Technical resource is failed integrated use, and high-end servo-driver function is shelved, and causes the technical resource waste, and increases the robot cost, demands urgently improving.
Summary of the invention
Problem for prior art exists the object of the invention is to propose a kind of network built-in type robot controller, by enforcement of the present invention, designs simplification, uses safety, easy operating, economizes on resources, reduces cost.
For reaching this purpose, the present invention by the following technical solutions:
A kind of network built-in type robot controller comprises:
The host computer of dedicated human interface is connected with servo-driver, communicates by letter the transmit operation instruction by wired or wireless mode;
Servo-driver, according to the operational order of described host computer, innernal CPU carries out exchanges data, direct control unit device human body motion;
Robot body directly accesses host computer by I/O equipment, or sensor and I/O equipment access host computer through carrying, to the host computer feedback information.
Preferably, the host computer of described dedicated human interface is connected into wide area network, realizes the control of Internet network remote.
Preferably, be provided with fire wall between the host computer of described dedicated human interface and the described wide area network.
Preferably, described dedicated human interface uses 7 " capacitance touch screen, ARM9 core, LINUX operating system, the hardware equipment I/O interface.
Compared with prior art, the present invention has following beneficial effect:
Network built-in type of the present invention robot, structural refinement has saved the intermediate equipments such as slave computer or PLC, and the trouble point is few; Adopt the theoretical control technology of closed loop, guaranteed without potential safety hazard; Network answer drives, and prevents from disturbing bringing unpredictable misoperation, guarantees the in real time accuracy of control; Open configuration can adapt to the establishment of most of techniques, need not to change source program, and versatility is stronger; The interface is clear, and is easy to operate, can understand fast the grasp method of operating; Native system integrates control and man-machine interface, greatly reduces in equipment cost, realizes that the thing favorable rates is honest and clean; Can be used as the long-distance centralized control monitoring terminal, realize factory automation, modernization.

The specific embodiment
The embodiment of the invention 1 provides a kind of network built-in type robot controller, as shown in Figure 2, comprising: Internet Long-distance Control, host computer (using the Special artificial interface), servo-driver, robot body.Wherein, dedicated human interface (host computer) is connected with servo-driver, communicates by letter the transmit operation instruction by wired or wireless mode; Servo-driver, according to the operational order of described host computer, innernal CPU carries out exchanges data, direct control unit device human body motion; Robot body directly accesses host computer by I/O equipment, or sensor and I/O equipment access host computer through carrying, to the host computer feedback information.In addition, dedicated human interface also can be connected into wide area network by fire wall, realizes the control of Internet network remote.
Wherein, dedicated human interface adopts 7 " capacitance touch screen, take ARM9 as core, LINUX operating system, the hardware equipment I/O interface.Deeply resolve the servo-driver communications protocol, with each driver Direct Communication of robot body, understand the inner motor servo driver coding of robot body, by network servomotor is controlled.Host computer receives the feedback signals such as external switch, pulse, sound, video, presses equipment work technological requirement, and robot body is carried out closed-loop control.
System is different according to different robot work characteristics, defined robot network's configuration table, the user can be according to the robot working environment, configuration robot duty freely, and complete robot work technique is kept in the memory, can name according to technique preserving content, can also define the duty code for technique, robot can understand the duty code, extracts automatically operation process.Robot Configuration Language friendly interface, lower dress is convenient, is fit to the various robots controls such as injection machine industry, spraying industry, engraving industry, electronic circuit processing industry.
The above; only be the better specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
