Abstract
The invention provides a processing method for position Hall switches. The processing method comprises the steps that signals of Hall sensors are sampled and analyzed, and the running position of a sunroof is acquired. The processing method is characterized in that the number of the adopted Hall sensors is two, the signals of the Hall sensors are sampled in the mode that the signals of the two Hall sensors are sampled at the same time, one Hall sensor serves as a main sensor and is used for calculation of the position of the sunroof, and the other Hall sensor serves as an auxiliary sensor and is used for calculation of the running direction of the sunroof. By the adoption of the processing method for the position Hall switches, both position judgment and direction judgment can be realized as long as one Hall sensor is additionally installed nearby a rotor of a sunroof motor, and the structure of the sunroof is simplified; besides, the auxiliary sensor can also be used as a standby sensor to realize redundant replacement of the sensors, and the stability and the safety of the sunroof in the running process are improved.
Description
Technical field
The invention belongs to auto parts machinery field, relate in particular to a kind of disposal route of the position Hall switch for skylight.
Background technology
The current judgement to skylight run location is by a Hall element being installed near the coil the rotor of skylight, being counted by the pulse signal to Hall element, further obtaining speed parameter, then binding time amount obtains location parameter.But the defect of prior art is, the location parameter calculating can not be distinguished and rotate and reverse, and therefore the judgement for position also needs other supplementary means to realize, and makes skylight structure become complicated.In addition, if this Hall element breaks down, the operation in skylight will be subject to irremediable impact so, even occur security incident.
Summary of the invention
The present invention has adopted a kind of disposal route of novel position Hall switch to solve the problems referred to above.The technical solution adopted in the present invention is as follows:
The disposal route of a kind of position Hall switch, comprise the signal of Hall element is carried out to sampling analysis, obtain the run location in skylight, it is characterized in that, the disposal route of described position Hall switch has adopted two Hall elements, the signal sampling of Hall element is comprised the signal of two Hall elements is sampled simultaneously, and one of them Hall element is used for calculating a day window position as master reference, and another Hall element is used for calculating skylight traffic direction as aiding sensors.
In said method, preferably, when master reference is working properly, according to the calculated signals location parameter of master reference, and by the calculated signals direction parameter of aiding sensors, when master reference operation irregularity, by the signal of aiding sensors, replaced the signal of master reference for calculating location parameter, and judge traffic direction according to key-press status and motor operating state.
When there is the abnormal situation of master reference, preferably further comprise and make skylight run to the step of not reruning in off-position and skylight.
Beneficial effect: the present invention is by adopting two Hall elements, by cooperating of main hall position sensor and auxiliary Hall element, accurately locates the position of skylight glass.In addition, by adopting redundant sensor, prevent the expansion of fault, improved security.Adopt method of the present invention, only need near the rotor of skylight motor, install again the dual judgement that a Hall element just can be realized position and direction additional, simplified the structure in skylight, and the redundancy that aiding sensors can also be realized sensor as backup sensors substitutes, and has improved stability and the security of skylight operation.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of the disposal route of position of the present invention Hall switch.
Embodiment
Below in conjunction with accompanying drawing, describe the present invention in detail.
Referring to Fig. 1, the disposal route of position of the present invention Hall switch has adopted two Hall elements, the signal sampling of Hall element is comprised the signal of two Hall elements is sampled simultaneously, signals collecting is after MCU, one of them Hall element is used for calculating a day window position as master reference, and another Hall element is used for calculating skylight traffic direction as aiding sensors.In this process, the signal that MCU generally also gathers motor and button is as auxiliary signal.
When master reference is working properly, according to the calculated signals location parameter of master reference, and by the calculated signals direction parameter of aiding sensors, so skylight can realize the normal function in skylight, such as softly opening, the position such as standard-sized sheet, perk.
And when master reference operation irregularity, by the signal of aiding sensors, replaced the signal of master reference for calculating location parameter, and judge traffic direction according to the signal of the key-press status of collecting and motor operating state simultaneously, thus realized redundancy location.In this case, MCU controls skylight and runs to off-position and control skylight and do not rerun, thereby has guaranteed security and do not make fault further expand.
By reference to the accompanying drawings embodiments of the present invention are described in detail above, but the invention is not restricted to above-mentioned embodiment, in the ken possessing at affiliated technical field those of ordinary skill, can also under the prerequisite that does not depart from aim of the present invention, make a variety of changes.
