The ivnention makes multi-group of motors and sensors receive and transport the needed information by use of the same circuit so as to save consumption of circuit, reduce designed complexity and low cost.
Description
The present invention relates to the device and method of a kind of gated sweep device multiple sets of motors and sensor.
General scanner is with movable image sensor or contact image sensor the file that is seated on the scanner to be scanned, and therefore just must have motor to drive moving of image sensor.In addition, some has the scanner of last light shield, and carry out of fluorescent tube in order to scanning can be set in last light shield.In this case, moving of last light shield interior lamp pipe also need be driven by motor.And if dispose automatic paper feeder, then the mechanism of paper feed also need be driven by motor automatically.Therefore, having more than one motor usually is arranged in the scanner.
Except motor, the situation of various sensors with checkout scanner also must be arranged in scanner, and will detect the parameter supply handling procedure of gained.For example, in the place of automatic paper feeder, generally have a sensor and be used for detecting whether the paper existence is arranged; And in the part of fluorescent tube or image sensor, also have sensor and be used for detecting the positions at these device places or mobile situation.
Therefore, in a scanner, can have the motor and the sensor of many groups usually.And prior art is used to control the motor control information of multiple sets of motors (serial or parallel) in processing, and during by the measured sensor status information of sensor, all adopts the separately method of control.Therefore, just need to use different signals for motor and sensor, and then cause the increase of signal wire quantity.Yet,, can increase the complicacy of system, the number of signal wire and the cost of manufacturing though this technology is the solution of intuition very.
Fundamental purpose of the present invention be to provide a kind of gated sweep device multiple sets of motors and sensor device and, switch the information of input as the control information of motor or the status information of sensor with one group of multiplexer; Multiple sets of motors can receive or transmit required information with sensor by identical circuit.Thereby save expending of circuit, reduce numerous and diverse in the design, reduce production costs.
The objective of the invention is to realize by the following technical solutions:
The device of a kind of gated sweep device multiple sets of motors and sensor comprises:
One shift register group, it comprises and is used to more than one to receive and the shift register of output information;
One bolt-lock registers group, it comprises the bolt-lock register that is used to keep respective shift register institute output information more than;
One multiplexer group, it comprises the multiplexer that is used for switching input shift register information more than between motor control information and sensor status information.
Described shift register is a reverser.
The information that the bolt-lock register is kept outputs to correspondingly on the motor.
The method of a kind of gated sweep device multiple sets of motors and sensor, it comprises the steps:
At least import the control information of a motor by more than one register;
Control information according to this motor drives corresponding motor;
At least import the status information of a sensor by this register;
Export this sensor status information.
The corresponding motor of described driving is: the operation that the control information of this motor is outputed to this motor when a detection signal produces.
Sensor status information is input in the register when this detection signal produces.
The present invention makes multiple sets of motors and sensor be received by identical circuit or transmits required information, has therefore saved expending of circuit, and has reduced design numerous and diverse, and then reduced production cost.
The present invention is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the structural drawing of a preferred embodiment of the present invention.
Fig. 2 is the signal timing diagram of a preferred embodiment of the present invention.
As shown in Figure 1, the device 10 of gated sweep device multiple sets of motors and sensor comprises: a shift register group 100, a bolt-lock registers group 120 and a multiplexer group 140.
In the present embodiment, comprise shift register 102,104,106 and 108 in the shift register group 100; Bolt-lock registers group 120 comprises bolt-lock register 122,124,126 and 128; Multiplexer group 140 comprises multiplexer 142,144 and 146.Wherein, shift register 102,104,106 and 108 can be respectively a reverser.
As shown in Figure 2, at first, motor control information DM1 is sent in the shift register 102 through signal wire Din, along with the change of Dclk signal (in the present embodiment, the Dclk signal is that rising edge triggers), motor control information DM1 can be sent among the bolt-lock register 122 when signal Dclk triggers.Simultaneously, motor control information DM1 also can be sent among the multiplexer 142.Because multiplexer group 140 is switched the information that it is sent by signal Dstrobe, when signal Dstrobe is low level, is respectively by input end 152,154 and 156 information of being imported by multiplexer 142,144 and 146 information of being exported; And when signal Dstrobe is high level, then be respectively by input end 162,164 and 166 information of being imported by multiplexer 142,144 and 146 information of being exported.Therefore, when signal Dstrobe was low level, the motor control signal DM1 that is sent to multiplexer 142 will be continued to be sent among the shift register 104.
Then, motor control information DM2 is among signal wire Din is sent to shift register 102.Equally, when next signal Dclk triggered, motor control signal DM1 can be sent among bolt-lock register 124 and the shift register 106, and motor control signal DM2 then can be sent among bolt-lock register 122 and the shift register 104.So repeat, among motor control information DM1, DM2, DM3 and DM4 are sent to bolt-lock register 128,126,124 and 122 respectively till.At this moment.It is flat that signal Dstrobe changes noble potential into by low level, and trigger bolt-lock registers group 120.Make motor control information DM1, DM2, DM3 and the DM4 be stored in bolt-lock register 128,126,124 and 122 outwards output among the motor control integrated circuit (not shown) by output terminal MOUT0, MOUT1, MOUT2 and MOUT3 respectively.
After motor control information output, sensor status information S1, S2 that is recorded by a plurality of sensors and S3 just can be input to respectively among multiplexer 146,144 and 142; This sensor status information S1, S2 and S3 can import or not input simultaneously simultaneously, because the signal Dstrobe of this moment still is a high level, so only can outwards be transmitted through multiplexer 142,144 and 146 respectively by input end 162,164 and 166 information of being imported.Therefore, sensor status information S1, S2 and S3 will be sent to respectively among shift register 108,106 and 104.Then, along with the triggering of signal Dclk, sensor status information S1 will be transmitted outward by shift register.Therefore, sensor status information S1 just can be continued to transmit outward by signal wire Sout again; Sensor status information S2 and the S3 of this moment then are sent to respectively among the input end 156,154; Along with the current potential of signal Dstrobe reduces, multiplexer 146,144 and 142 output just change into by input end 156,154 and 152 information of being imported.Therefore, sensor status information S2 and S3 be the mode to export in proper order just, and Sout outwards transmits through signal wire.
