Description
Technical field
The present invention relates to a kind of device that is used for the control gate driver, this device comprises path measurements device and control device, this path measurements device is used for detecting gate position and/or gate driver position and is used to launch corresponding door position signal, and this control device is used to depend on absolute value and at least one reference point of this door position signal and controls this gate driver.
Background technology
From the DE 19522622 C2 such gate driver of cicada, its utilization can reproduce a position the path measurements signal absolute value and utilize reference point to come work.One path measurements device is associated with the gate driver of wherein describing, and this path measurements device has the rotating potentiometer that can rotate according to moving of gate driver.Send the periodicity door position signal that moves according to door by potentiometer, but because the periodicity of signal, the absolute value of this signal can not clearly show this position.Yet in order clearly to measure this position, to the maximum value of potentiometer signal with minimum value is counted and it is considered as actual reference point.Then, use the absolute value of the reference point counted and the potentiometer signal after the corresponding reference point to carry out the mensuration of a position.Yet,, need the assessment to the potentiometer signal of relative complex for this known gate driver.On the one hand, minimum value must be measured and maximum value is counted it then.In addition, the accuracy of position finding and therefore the control accuracy of gate driver will be restricted, this is because except reference point, only just can carry out accurate position finding at the potentiometer signal that uses simulation.
Determine that for fear of such reference point WO 02/04775 A1 provides a kind of absolute value encoder that is used for detecting gate position or gate driver position, its signal always clearly reproduces the door position.Its use be a kind of absolute value encoder of inductive operation, this absolute value encoder reproduced constant dull increase or the constant dull door position signal that reduces in door position or gate driver position.Except this absolute value encoder, according to WO 02/04775 A1 can use itself be the known encoder that increases progressively also, this increases progressively encoder and produce the pulse of corresponding path when door moves, then these path pulses is counted correspondingly to control this gate driver.Stipulate that in this process this control procedure will use absolute value signal or increment signal to control this driver.Between absolute value signal and increment signal, be provided with switch with time division multiplexing (time multiplex) process work.Especially, when door is static, should use the absolute value signal of absolute value encoder, and when gate driver moved, described controller used the signal that increases progressively encoder.Yet in this process, use to increase progressively control and common operational issue can occur, for example the mistake in signal-count and the data volume etc.
Summary of the invention
Therefore, main purpose of the present invention is to provide improved gate driver control, and it is avoided the shortcoming of prior art and has further improved described prior art in an advantageous manner.Preferably can carry out inerrancy and sensitive control to gate driver with simple signal processing.
This purpose is that device by claim 1 solves according to the present invention.Preferred aspect of the present invention forms the theme of dependent claims.
Form contrast with known common prior art, the prior art---as according to teaching of the present invention---had not only been used the absolute value of door position signal but also had been used reference point to carry out control to gate driver, and the present invention has exempted the complexity of the signal maximum of absolute door position signalling and signal minimum is measured and to the counting of this maximum value and minimum value.In order to replace the invention provides two kinds of independently signals with the actual reference point on the complex way mensuration absolute door position signalling, promptly on the one hand, a kind of absolute door position signalling and a kind of reference point signal that is preferably data signal.This path measurements device is made by at least two passages, and comprises absolute value encoder and reference point encoder, and this absolute value encoder is used for launching absolute value signal on first passage, and the reference point encoder is used for launching a plurality of reference point signals at second channel.This control device is measured this control signal, so that by two kinds of signals gate driver is controlled coequally.Use the absolute value signal of relevant synchronous detection that corresponding reference point signal and other reference point signaling zone are separated.Then, this control device begins to control this gate driver from this corresponding definite reference point.Various possibilities have been caused by uniting the reference point signal that uses absolute value signal and produce respectively.On the one hand, also may use the absolute value signal of the non-constant dullness different with WO 02/04775A1.The clearly mensuration of opposite house position only need guarantee that to corresponding reference point signal and the combination of the absolute door position signalling of detection synchronously be clear and definite.For this purpose, it is contemplated that at least two kinds of different reference point signal types are provided.On the other hand, also may only come work with a kind of reference point signal type, promptly always when the different reference point of scanning and produce, at this moment absolute value encoder is launched the absolute value signal that clearly disperses on whole mobile route for identical reference point signal itself.With DE 19522622C2 relatively, might save the signal evaluation of effort by associating absolute value signal and the reference point signal that separates, promptly to the mensuration and the counting thereof of maximum value and minimum value.
In further improvement of the present invention, the path measurements device is by three passage manufacturings.Except absolute value signal and reference point signal, the path pulse produces on third channel when door or gate driver move by increasing progressively sensor.This control device begins to count the path pulse that these increase progressively from specified reference point, and the path umber of pulse that dependence is counted is come the control gate driver.By the path measurements signal that adopts these three kinds to mutually combine, promptly absolute value signal, reference point signal and increase progressively the path pulse can keep the advantage of single control system, and its shortcoming can be eliminated.Use absolute value signal to can be described as coarse adjustment control, promptly most reference points can be distinguished mutually with plain mode.In addition, when the manual operation of uncoupled axle of power-fail or door, reference point control and the FAQs that increases progressively control no longer play a role.This control device is always known, knows the residing position of door at least roughly.On the other hand, meticulous control becomes possibility by the path pulse that increases progressively encoder, and this point is impossible realize when using separately the always limited absolute value signal of resolution ratio.In this process, the processing that increases progressively code device signal is simplified by using reference point.
According to a particularly advantageous embodiment of the present invention, absolute value encoder and reference point encoder are combined in the single-sensor.Two channel-type path sensor particularly can be provided, wherein can integrated described absolute value encoder and reference point encoder.Except this two channel-types path sensor, can provide one itself to be the path signal encoder that increases progressively separately.
In further improvement of the present invention, potentiometer can be used as absolute value encoder, and it preferably launches clearly discrete absolute value signal at the whole mobile route of door and/or gate driver.Voltage switch can be used as the reference point encoder.Potentiometer is become possibility to voltage switch to these two unit constructions as making with reference to the design of putting encoder with plain mode as absolute value encoder in single-sensor.
Advantageously path sensor has the signal coder element, and it can be according to moving of door and/or moving of gate driver, and handle (actuate) absolute value encoder and reference point encoder by this.The signal coder element can particularly load two pick-ups, and one of them handles potentiometer circuit, another steering voltage switch.
In the favourable further improvement of the present invention, the circuit of potentiometer circuit and formation voltage switch is arranged in on-chip concentric circles form, and described signal coder element is rotatably supported with respect to this substrate.Described signal coder element rotates according to mobile or the moving of gate driver of door on substrate, and in this process, handle potentiometer circuit, make this absolute value signal to use, and handle this and form voltage switch and be the circuit of the corresponding mobile transmitted-reference point of door.
