Description of drawings
Fig. 1 is the structural representation of the display of a kind of integrated with distance measurement function provided by the invention.
Embodiment
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
Fig. 1 is the structural representation of the display of a kind of integrated with distance measurement function provided by the invention.
Referring to Fig. 1, the invention provides a kind of display of integrated with distance measurement function, be connected with host computer, this display includes the sight protectio distance unit 101, range cells 102 and comparing unit 103 is set, wherein:
The sight protectio distance is provided with unit 101, is used to set in advance the sight protectio distance of display and store;
Comparing unit 103; with sight protectio distance unit 101 is set respectively, range cells 102 is connected; being used in real time described sight protectio distance being provided with the distance that the sight protectio distance of storing unit 101 and range cells 102 detect between acquisition user and the display compares; sight protectio distance greater than between user and the display apart from the time, the outside host computer that links to each other of trigger scope enters holding state.
In the present invention, described sight protectio distance is provided with unit 101 and is preferably nonvolatile random access memory NVRAM.
On specific implementation of the present invention, the user can be by preestablishing the sight protectio distance of described display among the menu MENU.
In the present invention, described range cells 102 is preferably distance measuring sensor.It is several that described distance measuring sensor includes ultrasonic ranging sensor, laser range sensor, infrared distance sensor etc.
In the present invention, described range cells 102 is preferably the employing infrared distance sensor.The present invention reaches the purpose of the distance between real-time detection user and the display by infrared distance sensor is installed on display.
In the present invention, described comparing unit 103 is the central processor CPU of display.
Need to prove that infrared distance sensor is an obstacle distance difference of utilizing infrared signal to run into, the principle that reflection strength is also different is carried out the detection of barrier distance.Infrared distance sensor has a pair of infrared signal emission and reception diode; the infrared signal of power valve emission characteristic frequency; receiving tube receives the infrared signal of this frequency; when infrared detection side is before the people is sitting in computer the time to barrier is arranged; infrared signal reflects and is received the pipe reception; after treatment; turn back to the central processor CPU of display by digital sensor interface; CPU can utilize infrared return signal to judge that relatively whether this distance is less than default sight protectio distance; if less than the sight protectio distance; trigger the PC PC main frame that is connected with display and enter holding state, thereby prevented that the user from closely using display.
In addition, need to prove also that above-mentioned infrared distance sensor is far and near according to the distance of institute's inspected object, in real time aanalogvoltage U of output
SurveyThe distance of object to be detected is far away more, the analog voltage of output that this infrared distance sensor produces is just more little, otherwise, the distance of object to be detected is near more, the analog voltage of output that this infrared distance sensor produces is just big more, and promptly the distance of object to be detected is inversely proportional to the analog voltage size of output that infrared distance sensor produces.
In the present invention, based on as mentioned above,, can obtain at the pairing protection aanalogvoltage of the object to be detected of guard space U by infrared distance sensor
0, at this moment, above-mentioned sight protectio distance is provided with unit 101 and is used to set in advance the sight protectio distance of display and the protection aanalogvoltage U of the pairing infrared distance sensor output of this sight protectio distance
0And store;
Based on as mentioned above, when infrared distance measuring sensor the aanalogvoltage U of output in real time
SurveyProtection aanalogvoltage U greater than the pairing infrared distance sensor output of sight protectio distance
0The time, the distance of its inspected object is less than the sight protectio distance of display, and can enter holding state by the outside host computer that links to each other of trigger scope this moment.
Therefore, when described range cells 102 was preferably infrared distance sensor, described comparing unit 103 was preferably voltage comparator, and this voltage comparator is used in real time with the protection aanalogvoltage U of sight protectio apart from pairing infrared distance sensor output
0With infrared distance sensor the real-time aanalogvoltage U of output
SurveyCompare, at protection aanalogvoltage U
0Less than infrared distance sensor the real-time aanalogvoltage U of output
SurveyThe time, the outside host computer that links to each other of trigger scope enters holding state.
On the specific implementation; with 22 cun displays is example, and in view of when using computer, the optimum distance of user and display should remain on 50-60cm; preestablish the sight protectio distance so and be 50cm, the aanalogvoltage of the pairing infrared distance sensor output of this sight protectio distance is U
0, the aanalogvoltage U that exports in real time of infrared distance sensor institute relatively
SurveyAnd U
0, judge U
SurveyWhether greater than U
0, if greater than U
0, the then PC standby of entering; If less than U
0, distance between user and the display is described greater than the sight protectio distance, then continue the normal display that uses.
In sum; compared with prior art; the display of a kind of integrated with distance measurement function provided by the invention; it can be the user who uses computer during too near display; trigger computer and enter holding state, thereby prevent that computer user from closely using display, the eyesight of protection computer user; safeguard their healthy, be of great practical significance.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
