The utility model can ensure that a plurality of motors are driven by the motor controller, thereby reducing the amount of motor controllers and greatly saving the cost.
Description
(1) technical field
The utility model relates to a kind of circuit board that is used to control servomotor, specifically relates to a kind of circuit board that a plurality of servomotors are controlled in timesharing step by step that is used for.
(2) background technology
In traditional motor-driven solution, generally by motor of the corresponding driving of a controller.The number of motors that drives when needs is more and require when high driving efficient, and traditional motor control schemes needs numerous servomotor and electric machine controller, but this has just caused the sharp increase of cost, has limited application.
(3) utility model content:
The purpose of this utility model is to propose a kind of circuit board that is used to control servomotor, can realize motor is controlled in higher efficiency with lower cost.
The utility model is a kind of circuit board that is used to control servomotor, and its structure comprises as shown in Figure 1:
An electric machine controller that is connected with peripheral interface;
A decoder that is connected with peripheral interface;
A plurality of transceivers,
A plurality of relays;
A plurality of binding posts;
A signal wire interface; And
A power interface;
Wherein, electric machine controller connects whole relays and whole transceiver, and decoder connects whole transceivers, and per two relays and a transceiver are connected to a connecting terminal of motor; Binding post connects peripheral controlled motor.
Wherein, the quantity of transceiver, relay and binding post depends on the quantity of the peripheral controlled servomotor of the utility model circuit board, is respectively a times, two times and a times of servomotor quantity.
Wherein, described transceiver is ternary bidirectional bus transceiver.
Wherein, described relay is the electric parameters relay, is preferably solid-state relay.
Preferably, described peripheral interface is CAN bus interface, RS232 interface, PCI-1730 industry control card, analog quantity input/output interface, digital quantity input/output interface.
And, in order to reduce the area of circuit board, guaranteeing the reasonable installing space of components and parts simultaneously, this circuit board adopts two stacked layouts of control board.
Advantage of the present utility model is: binding post connects electric machine controller by transceiver, its feedback be the state information of motor; Electric machine controller is handled the control signal of peripheral interface; Decoder is handled the gating signal of peripheral interface, determine that by gating signal a certain group of transceiver and relay are by gating, the motor feedback signals that will be come from binding post (motor) by the transceiver of gating passes to electric machine controller, the control power turn-on that will be come from electric machine controller by the relay of gating is to binding post (motor), to guarantee the pairing motor Be Controlled of this binding post (driving).Any motor be selected and be controlled to Control Software can by the control gating signal.The utility model can be realized driving several motors by an electric machine controller, thereby has reduced the quantity of electric machine controller, and bigger provides cost savings.

(5) embodiment
In order to understand the utility model better, by a preferred embodiment the utility model is elaborated below in conjunction with accompanying drawing.
Fig. 1 is the structure chart of present embodiment, comprises following components and parts: 1 electric machine controller, 1 decoder, N binding post (N DC servo motor), a N transceiver, a 2N relay, 1 RS232 interface, 1 PCI-1730 interface, 1 power interface.
Fig. 2 is the winding diagram of present embodiment.N binding post connects a peripheral N controlled DC servo motor.2N relay, a N transceiver and N binding post are divided into the N group: promptly per two relays, 1 transceiver and 1 binding post are formed one group, have 1,2 like this ..., the N group, 1,2 of corresponding periphery ..., N controlled DC servo motor.
Electric machine controller is connected to whole 2N relay and whole N transceiver, and decoder connects whole N transceiver, and per two relays and a transceiver are connected to a binding post simultaneously.
Because the quantity of relay and components and parts such as transceiver, binding post is more, for making the occupied area of entire circuit plate littler, with all components and parts cloth on two stacked planks.
Electric machine controller mainly is responsible for receiving the control signal that peripheral industrial computer provides through the RS232 interface, and be converted to the CAN bus signals, to control power supply by relay and issue binding post (promptly arriving controlled DC servo motor), controller receives the controlled DC servo motor information returned by transceiver simultaneously and it is returned to industrial computer.Here, electric machine controller also can directly be accepted the signal that the CAN bus interface of peripheral industrial computer provides.
The signal that the mainly responsible reception PCI-1730 of decoder interface provides comes the transceiver and the relay of gating appointment.
Behind the some transceivers of decoder gating, with its also conducting of relay on the same group, then controller is got through with the communication between the corresponding controlled motor, and the motion of motor is by motor controller controls.Such as, decoder gating the transceiver in the 2nd group, promptly the both-way communication of No. 2 motors and electric machine controller is got through, simultaneously, the relay conducting in the 2nd group, No. 2 motor obtains external drive voltage, then controller can be controlled the running of No. 2 motors; Controller is finished according to the instruction of industrial computer after the control to No. 2 motors, continues any another one motor of control decoder gating.So, present embodiment has been realized only finishing with a controller timesharing distribution of a plurality of DC servo motor is controlled, thereby has reduced the quantity of controller, and bigger provides cost savings.
Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example; variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection range of the present utility model.
