Embodiment
The utility model PC with the course of work of sight protectio monitoring device is: as depicted in figs. 1 and 2; at first this PC is arranged on the display of PC with the range cells 1 that is used to measure distance between the display of PC and the people's face of sight protectio monitoring device; range cells 1 is sent to signal processing unit 2 with distance measuring signal; if record the display of PC and the distance between people's face when setting threshold values; signal processing unit 2 sends alerting signal to alarm unit 3; alarm unit 3 receives the report for police service and sounds behind the signal or light is reported to the police; the prompting operator notes the distance between face and the PC display, thereby effectively protects operator's eyesight.
As shown in Figure 2, described signal processing unit 2 comprises A/D modular converter 2-1, CPU control module 2-2 and I/O communication module 2-3; Described A/D modular converter 2-1 is connected with range cells 1, and the ranging information that described range cells 1 is sent is carried out the A/D conversion; Described CPU control module 2-2 is connected with I/O communication module 2-3 with A/D modular converter 2-1 respectively, reception will output to described alarm unit 3 by I/O communication module 2-3 according to the alarm command that ranging information produces through the ranging information of A/D modular converter 2-1 conversion process.
Described alarm unit 3 is hummer or LED light.
Embodiment 1
As shown in Figure 3, PC display 4 left and right sides all are equipped with scalable rigid rod 1 and the scalable rigid rod 27 that has scale by stator 5, the end of described scalable rigid rod 1 is equipped with infrared transmitting device 8, described scalable rigid rod 27 ends are equipped with infrared receiver 9, described infrared receiver 9 is connected with controller 10 by data line, and described controller 10 inside are integrated with acoustic-optic alarm.
