The invention provides a kind of trace input device, it comprises an induction module and an operational module.Trace input device can be as a computer peripheral equipment, and computing machine can have a display.The user can operate operational module, with control, is shown in the vernier on display and computing machine is operated.
Please first with reference to Fig. 1, the block diagram of its trace input device that is an enforcement example.
It comprises induction module 20 and operational module 30 trace input device.For example, induction module 20 can be electromagnetic digital board or electromagnetic type plotting sheet, and operational module 30 can be the electromagnetic type digital pen.Because induction module 20 and operational module 30 adopts the locator meams of electromagnetic types, so the user is while operating operational module 30, and operational module 30 can touch induction module 20.But the user also can be resisted against operational module 30 surface of induction module 20 and slide, and the pen that operational module 30 can the sensing user applies is pressed.
Induction module 20 comprises an inductive coil 21, one first communication unit 22 and one first control module 23; And operational module 30 comprises a set winding 31, one second communication unit 32, one second control module 33 and a plurality of motor unit 34.Wherein inductive coil 21 and the first communication unit 22 are connected with the first control module 23; Set winding 31, the second communication unit 32 and each motor unit 34 can be connected with the second control module 33.
For the position of precise assembly module 30 with respect to induction module 20, set winding 31 sends a location signal, and inductive coil 21 utilizes the principle of electromagentic resonance (electromagnetic vibration) receive positioning signal and export according to this trajectory signal.And the track that the corresponding user of trajectory signal draws with operational module 30.
Between the first control module 23 and the second control module 33, can carry out two-way communication by the first communication unit 22 and the second communication unit 32.In order to carry out two-way communication, the first communication unit 22 output one first control signals also receive one second control signal, and the second communication unit 32 is in order to receive the first control signal and to export the second control signal.Wherein the first communication unit 22 and the second communication unit 32 can be a radio frequency integrated circuit (Radio frequency integrated circuit, RFIC).Yet the communication modes that the first communication unit 22 and the second communication unit 32 also can adopt other low-power consumption and can produce not disturb with positioning signal, such as RF2.4G etc.
Each motor unit 34 can produce an actuating signal.Motor unit 34 can be one and press sensor, a button, a roller or a resistance-type adjuster.For example, the outward appearance of operational module 30 can be pen type, configurable at least one button in the penholder outside, and at nib and configurable of pen core place pressure detecting device.And the resistance-type adjuster can be variohm (variable resistor), but for example implementation becomes a knob (knob) or a slide bar (sliding bar).Button, roller or resistance-type adjuster can be performed according to computing machine application program different definition is arranged.For example, when the application program in using is mapping software, operational module 30 can imitate various paintbrushes; And the user can by the resistance-type adjuster adjust paintbrush kind, thickness, color or and drawing paper between contact angle.
Again for example, when motor unit 34 is pen pressure sensor, it can detect the pen pressure that the user applies, and the actuating signal of an output representative Compressive Strength.When motor unit 34 is button, it can send the actuating signal that represents that whether button is pressed.When motor unit 34 is roller, it can send the actuating signal that represents roller rotating direction and rolling distance.When motor unit 34 is turn-knob or slide bar, it can send the actuating signal that represents current resistance value, also can send the actuating signal that represents moving direction and displacement.
Please refer to Fig. 2, the two-way communication process flow diagram of its first control module that is an enforcement example and the second control module.
At first, the first control module 23 produces the first control signal (step S110), and makes the first communication unit 22 that the first control signal is sent to the second communication unit 32.The second control module 33 receives the first control signal (step S120) from the second communication unit 32.Then the second control module 33 can receive at least one actuating signal from least one motor unit 34 according to the first control signal, and produces the second control signal (step S130) according to the actuating signal received.
Among step S130, the first control signal can be specified at least one motor unit 34; The second control module 33 receives at least one actuating signal from appointed motor unit 34 again, and produces the second control signal according to the actuating signal received.For example, the first control module 23 may need regularly to obtain a Compressive Strength, and therefore can regularly send content is the first control signal that requires current Compressive Strength.After the second control module 33 is received this one first control signal, just go to read an actuating signal that the pressure detecting device produces, then the actuating signal read is returned to the first control module 23 as the second control signal.
Again for example, when the application program in using only needs a Compressive Strength and button whether to be pressed, the actuating signal that the first control module 23 can only require a pressure detecting device and button to produce to the second control module 33.Thus, can make particular action unit 34 anergies (disable), with avoid should the generation effect because of user's false touch particular action unit 34 generating programs process wrong or other expect outer error result.
After producing the second control signal, the second control module 33 makes the second communication unit 32 that the second control signal is sent to the first communication unit 22.The first control module 23 receives the second control signals from the first communication unit 22, and can be from inductive coil 21 receiving locus signals, then produces an output signal (step S140) according to trajectory signal or the second control signal.
Thus, utilize the two-way communication mechanism between induction module 20 and operational module 30, can heavily send positioning signal, the first control signal and the second control signal simultaneously, and then induction module 20 is synchronizeed with the information between operational module 30.Although the content of the first control signal and the second control signal can, as described in the enforcement example of Fig. 2, also can have other guide.For example operational module 30 can initiatively send to induction module 20 using actuating signal as the second control signal by the first communication unit 22 and the second communication unit 32 according to default scheduling (scheduling), communication module 30 can be replied acknowledgement (acknowledgement, ACK) as the first control signal by the first communication unit 22 and the second communication unit 32 again.
According to an enforcement example, inductive coil 21 can send a charging signals; And set winding 31 can receive charging signals and produce an electric power signal, as the power source for operational module 30 runnings.Please refer to Fig. 3, the block diagram of its operational module that is an enforcement example.

According to an enforcement example, operational module 30 also can comprise a built-in battery, to keep in electric power signal.Please refer to Fig. 4, the block diagram of its operational module that is an enforcement example.Battery 38 can connect rectification unit 37 and the second control module 33, and to store the electric power signal of rectification, and the electric power signal of output rectification is given the second control module 33.Rectification unit 37 can be connected with the second control module 33 by battery 38.
The second control module 33 can judge whether according to the dump energy of battery 38 to be charged, and can utilize the first communication unit 22 and the second communication unit 32 and the first control module 23 to be linked up, to control the flow process of charging.
Please refer to Fig. 5, the process flow diagram of its charging flow that is an enforcement example.
At first the second control module 33 can judge whether the dump energy of battery 38 is less than one first threshold value (step S210), and when the dump energy of battery 38 is less than the first threshold value, trace input device is carried out following steps S220 to step S240.When the dump energy of battery 38 is less than the first threshold value and need to be charged, the second control module 33 can produce a charging commencing signal and one the 3rd control signal (step S220).The commencing signal that wherein charges sends to switch 35, and the 3rd control signal sends to the first control module 23.The first control module 23 can receive the 3rd control signal by the first communication unit 22 and the second communication unit 32.When the first control module 23 is received the 3rd control signal, can make inductive coil 21 start to send charging signals (step S230).And, when switch 35 receives the charging commencing signal, switch 35 can make set winding 31 be connected to rectification unit 37(step S240).Therefore set winding 31 can receive charging signals, and sends charging signals to rectification unit 37 and carry out rectification, and then to battery 38 chargings.
When the dump energy of battery 38 is not less than the first threshold value, the second control module 33 can judge whether the dump energy of battery 38 is greater than one second threshold value (step S250).When the dump energy of battery 38 is greater than the second threshold value, trace input device is carried out following steps S260 to step S280.When the dump energy of battery 38 is greater than the second threshold value and can stops charging, the second control module 33 can produce a charging end signal and one the 4th control signal (step S260).The end signal that wherein charges sends to switch 35, and the 4th control signal sends to the first control module 23.The first control module 23 can receive the 4th control signal by the first communication unit 22 and the second communication unit 32.When the first control module 23 is received the 3rd control signal, can make inductive coil 21 stop sending charging signals (step S270).And, when switch 35 receives the charging end signal, switch 35 can be switched and be made set winding 31 to be connected to oscillatory circuit 36(step S280).Therefore set winding 31 can continue to send positioning signal, with precise assembly module 30.
In addition, actuation means 30 also can also comprise a charge coil, to receive charging signals and to send positioning signal simultaneously.Please refer to Fig. 6 and Fig. 7, it is respectively the different block diagrams of implementing the operational module of example.
Operational module can also comprise charge coil 39, and charge coil 39 can be in order to receive charging signals and to produce electric power signal.Rectification unit 37 can connect charge coil 39 and the second control module 33, in order to the rectification electric power signal, exports to the second control module 33 again.Yet battery 38 also can be arranged to keep in the electric power signal of rectification between rectification unit 37 and the second control module 33.Preferably, positioning signal that the charging signals that induction module 20 sends and operational module 30 send adopts different frequency, between signal, interferes with each other avoiding.
Similarly, induction module 20 also can comprise that a power supply coil is to receive positioning signal and to send charging signals simultaneously.And be similar to the described charging flow of Fig. 5, the first control module 23 can just make inductive coil 21 or power supply coil send charging signals after receiving the 3rd control signal, and after receiving the 4th control signal, make inductive coil 21 or power supply coil stop sending charging signals, constantly send charging signals with the coil of avoiding powering and cause energy dissipation.
According to also one implementing example, in operational module 30, battery 38 can be arranged, but there is no charge coil 39 and rectification unit 37, as Fig. 8.Battery 38 can be detachable dry cell, button cell or rechargeable battery, and only in order to power to operational module 30.
In sum, induction module can utilize set winding and inductive coil operational module to be positioned and obtains trajectory signal, also can utilize the first communication unit and the second communication unit and operational module to carry out two-way communication.And utilize the mechanism of two-way communication, sensing unit can obtain required actuating signal, also can learn the opportunity that need to be charged to operational module.And the first communication unit and the second communication unit can adopt the shorter but communication modes of low-power consumption of communication distance, and can provide for a long time and two-way communication continually.In addition, the communication of the first communication unit and the second communication unit can be in digital communication, and the electromagnetic wave (positioning signal) that therefore can not send with set winding produces and disturbs.
