A preferred embodiments of the present utility model relates to a kind of range sensor calibrating installation of portable terminal, comprises: the portable terminal, portable terminal anchor clamps, vernier caliper, the test card that have range sensor.
Specifically, as shown in Figure 1, portable terminal anchor clamps 201 clamp portable terminal 204, vernier caliper 202 and portable terminal anchor clamps 201 vertical fixing.Test card 203 flexibly connects with vernier caliper 202, and this test card 203 is positioned at portable terminal anchor clamps 201 tops, and is parallel with the portable terminal anchor clamps, and can move along the above-below direction of vernier caliper 202.Vernier caliper 202 is used for measuring test card 203 from the accurate distance of portable terminal 204, range sensor in the portable terminal is with the standard shelter of test card 203 as range sensor, the infrared energy that detecting is returned by infrared lamp emission infrared energy back reflection carries out the threshold values of range sensor apart from the calibration of energy value for portable terminal according to the described infrared energy that reflects.Wherein, range sensor comprises infrared discharge lamps 206 and infrared remote receiver 205.
Below will describe the utility model with the example that is applied as of intelligent mobile terminal D9001, certainly, the utility model is not limited thereto, and going for arbitrarily, other adopt the portable terminal of range sensor.
As shown in Figure 1, portable terminal anchor clamps 201 are fixed together vernier caliper 202, test card 203 and portable terminal 204, and test card 203 can move along the above-below direction of vernier caliper 202.Test card 203 generally selects for use the card of white or photography to block with white balance verification ash.The reflectivity of the outer 850NM of general white carminum is 90%, and the reflectivity of the outer 850NM of grey carminum is 18%, so when using different object of reference, the standard of distance is also different.Normal accepted standard: 90% white card 5CM display screen dark (is that test card is when being the card of white, described threshold values is 5 centimetres apart from the threshold values distance of the screen lamp deepening of energy value correspondence), 18% ash card 2CM display screen dark (being that test card is that described threshold values is 2 centimetres apart from the threshold values distance of the screen lamp deepening of energy value correspondence when photographing with white balance verification ash card).The utility model adopts 18% ash card.
The portable terminal 204 of calibration to be tested is D9001, range sensor receiver 205 adopt CAPELLA companies CM3623, range sensor infrared lamp 206 adopts the CM3650 of CAPELLA companies.
The operation principle of present embodiment is as follows: CM3623 can detect the infrared energy that is reflected by the infrared lamp emission.Many height of energy by reflection come judging distance, and generally speaking energy is more high, and distance is more near.Mobile terminal processor can read 8 (binary system) energy output valves of CM3623 range sensor by the I2C bus.
Particularly, the adjust the distance unobstructed energy value of transducer and threshold values of portable terminal composed an empirical value apart from energy value, and is kept at the storage area that can not wipe on the portable terminal.Wherein, unobstructed energy value is that the range sensor top does not have test card to block under the situation, the energy value that receiver receives, the energy value that receiver receives when testing many distance of mobile terminal transducers and not having shelter is up got wherein maximum as the empirical value of unobstructed energy value.Threshold values is that a certain threshold values in range sensor top blocks under the situation energy value that receiver receives apart from adding test card apart from energy value.

Wherein, the unobstructed calibration of range sensor realizes in the following manner: under the situation that does not have test card to block, repeatedly read the energy value that the range sensor receiver receives, the energy value that reads is averaged, if mean value less than the empirical value of the unobstructed energy value of initialization module, shows successfully; Otherwise, showing failure, the unobstructed calibration failure of prompting user please its inspection.
The successful portable terminal of unobstructed calibration is carried out the threshold values of range sensor apart from the calibration of energy value.May further comprise the steps particularly: test card is placed on the threshold values distance of the top of portable terminal, repeatedly reads the energy value that the range sensor receiver receives.The energy value that reads is averaged, this mean value is substituted the threshold values set in advance apart from energy value, with test card along vernier caliper near the portable terminal certain distance, repeatedly read energy value, the energy value that reads is averaged, if mean value apart from energy value, is closed screen lamp greater than threshold values.Then, test card is surpassed the threshold values distance along vernier caliper away from portable terminal, repeatedly read energy value, the energy value that reads is averaged, if mean value is opened screen lamp less than the difference of threshold values apart from energy value and marginal error, show and calibrate successfully; Otherwise, show the calibration failure.Wherein, marginal error be used for preventing test card threshold values apart from the time screen phenomenon appears dodging.
Specifically, the unobstructed calibration of range sensor is fixed on portable terminal D9000, vernier caliper on the portable terminal anchor clamps 201 shown in Figure 1 as shown in Figure 3.Then, start portable terminal D9000, enter range sensor calibration interface, carrying out unobstructed calibration by human-computer interaction interface prompting user is current.Then, read the energy value that the receiver of N (as 10 times) range sensor receives, and calculate its mean value.If mean value is less than the empirical value of default unobstructed energy value, then screen display " unobstructed calibration success " enters the threshold values of range sensor then automatically apart from the calibration flow process of energy value; If the mean value that calculates, then shows " unobstructed calibration failure please check " more than or equal to the empirical value of default unobstructed energy value.
The threshold values of range sensor apart from the calibration flow process of energy value as shown in Figure 4.At first, by human-computer interaction interface prompting user test card is moved to 2cm place, screen top.Then, read the energy value that the receiver of N (as 10 times) range sensor receives, and calculate its mean value, this mean value is substituted default threshold values apart from energy value.Then, with test card along vernier caliper near portable terminal 1cm, read energy value, the energy value that reads averaged for 10 times.If mean value is less than or equal to threshold values apart from energy value, then show " calibration failure "; If mean value apart from energy value, is then closed screen lamp greater than threshold values, test card is moved to distance B 9000 screen 3cm places, read energy value, the energy value that reads is averaged for 10 times.If mean value is 2 less than threshold values apart from marginal error in energy value-2(present embodiment), then open screen lamp, show " calibrating successfully ", otherwise show " calibration failure ".
Be not difficult to find, in the present embodiment, owing to utilized test card mock standard shelter, make range sensor in the portable terminal can actual measurement test card from the distance of screen be the screen lamp deepening threshold values apart from the time, the infrared energy that reflects, and carry out threshold values on this basis apart from effective calibration of energy value.Namely have when different slightly when the relative position of infrared lamp and receiver and angle have different slightly, touch-screen material, for same shelter, even if the energy that receiver receives is different, but can under a certain identical critical distance, make the screen deepening.For manufacturer, can improve the consistency of portable terminal volume production middle distance sensor performance, for the user, can make the range sensor of portable terminal be operated in a relatively reasonable state.
