Description of the Invention: [Technical Field] The present invention relates to a prompting technique, and more particularly to a prompting system applied to a projector. [Prior Art] When the projector is in use, the projector will have an abnormal state inside for a long time. If the temperature inside the projector is too high, the fan speed inside the projector is low or the lamp usage time has reached or exceeded, which affects the projector. normal work. Generally, a display light is set on the projector to light up to remind the user (viewer) when an abnormality occurs inside the projector, so as to be processed accordingly. However, the display light is generally disposed on the side of the projector casing, and the user cannot ensure that the state of the display lamp is noticed at any time during use, and when the projector is set at a higher position for projection, the projector and the user and the viewer The distance between the people is far away, and the user cannot see the status of the indicator light. Therefore, when an abnormality occurs in the projector, the user cannot perform corresponding processing in time, resulting in damage to the projector. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a projector prompting system capable of displaying prompt information in advance when an abnormality occurs in a projector. A projector prompt system for displaying prompt information on a projection screen. The projector prompting system includes a detecting unit and an early warning unit, and the detecting unit is electrically connected to the early warning unit. The detecting unit is configured to detect the projector and obtain at least one detected value, and the early warning unit 1373683^ presets at least one comparison threshold corresponding to the at least one detected value. The early warning unit includes an adjustment unit that adjusts the at least one comparison threshold to obtain at least one adjustment threshold. The warning unit compares the at least one adjustment threshold with the at least one detection value to determine whether the at least one detection value exceeds a detection value range when the projector is in normal operation, when the at least one detection value exceeds the projector When the range of detection values during normal operation is displayed, the information is displayed on the projection screen. Compared with the prior art, the projector prompting system uses the adjustment unit to adjust the preset comparison threshold in the early warning unit and obtain a corresponding adjustment threshold, and simultaneously adjusts the detection value of the detection unit and the corresponding adjustment. The threshold is compared to determine whether the detected value exceeds the detection range of the projector during normal operation. When the detected value exceeds the detection range of the projector during normal operation, the prompt information is displayed on the screen. The projector prompting system can display the prompt information on the projection screen in advance when the projector is abnormal, so that the user can know the abnormal situation of the projector in advance in order to take corresponding measures. ® [Embodiment] Hereinafter, embodiments of the present invention will be further described in detail with reference to the accompanying drawings.

The early warning unit 12 includes a storage unit 14, a comparison unit 16, and an adjustment unit 18. The temperature detecting unit 10, the comparing unit 16, and the storage unit 14 are electrically connected in sequence. The adjusting unit 18 is electrically connected to the storage unit 14 and the comparing unit 16, respectively. The storage unit 14 internally presets a comparison threshold of the temperature in the projector and stores a prompt information. In this embodiment, the preset comparison threshold is T2. The comparison threshold T2 is the maximum (high) temperature value at which the projector is allowed to operate, and is generally set in the storage unit 14 of the early warning unit 12 at the time of shipment. In this embodiment, the adjusting unit 18 adjusts the comparison threshold Τ2 of the temperature in the projector stored in the storage unit 14 to obtain an adjustment threshold Τ3, and the adjustment threshold Τ3 is smaller than the comparison threshold Τ2, and the general adjustment range is about 3 °C. For example, T2=5 (TC, T3=47° C. • The comparison unit 16 of the early warning unit 12 receives the detection value of the detection unit 10 and the adjustment threshold T3 of the adjustment unit 18. At the same time, the detection value is compared with the adjustment threshold Τ3, when When the detection value L is greater than the adjustment threshold Τ3, the detection value is beyond the detection range of the temperature during normal operation of the projector, that is, when TpTg, the prompt information is displayed on the projection screen to the user, so as to promptly remind the corresponding measures to prevent the cause If the internal temperature of the projector is too high, the projector will automatically shut down and damage the projector. Please refer to FIG. 2, which is a projector prompting system 200 according to a second embodiment of the present invention. The projector prompting system 200 and the projector 137368.3 of the first embodiment are shown.

The fan rotation speed detecting unit The comparison unit 26 and the storage unit 24 are electrically connected in sequence. The adjustment unit 28 is electrically connected to the storage unit 24 and the comparison unit 26. The internal fan of the projector is preset in the storage unit 24. In the present embodiment, the comparison threshold value is N2. The comparison threshold value N2 is the minimum rotation speed value of the fan when the projector is allowed to operate, and is generally set in the storage unit 24 of the early warning unit 22 at the time of shipment. In this embodiment, the adjustment unit 28 adjusts the comparison threshold N2 of the fan speed in the projector stored in the storage unit 24 to obtain an adjustment threshold N3. The adjustment threshold N3 is greater than the comparison threshold N2, and the adjustment range is generally 20 rpm. For example, N2=500 rpm, then N3=520 rpm. The comparison unit 26 of the warning unit 22 receives the detection value ratio and the adjustment. The threshold value N3 is compared with the detection value A and the adjustment threshold value N3. When the detection value A is smaller than the adjustment threshold value N3, the detection value K exceeds the detection value range of the fan rotation speed when the fan is working normally, that is, when the ΝγΑ is on the projection screen. The prompt information is displayed. 9 1373683 _ The projection prompt system 200 of the embodiment has the same basic functions as the projection prompt system 100 of the first embodiment, except that the detected object is different. When detecting the speed value of the fan in the projector When less than the adjustment threshold in the early warning unit, the prompt information is displayed on the projection screen. Please refer to FIG. 3, which is a projector prompting system 300 according to a third embodiment of the present invention. The projector prompting system 300 is basically the same as the projector prompting system 100 of the first embodiment, except that the detecting unit and the early warning unit are different. The projector prompting system 300 includes a bulb usage time detecting unit 40 and an early warning unit 42. In the present embodiment, the bulb use time detecting unit 40 is for detecting the use time of the projector bulb. The bulb use time detecting unit 40 detects the use time of the bulb in the projector and obtains a detected value. In this embodiment, the detection value is Μ:. The detecting unit 40 is a device that can detect Μ! The lamp in the projector is used for the cumulative usage time of the lamp from its inception to its current use. The early warning unit 42 includes a storage unit 44, a comparison unit 46, and an adjustment unit 48. The bulb use time detecting unit 40, the comparison unit 46, and the storage unit 44 are electrically connected in sequence. The adjusting unit 48 is electrically connected to the storage unit 44 and the comparing unit 46, respectively. The storage unit 44 of the warning unit 42 stores a comparison threshold of the usage time of the bulb in the projector and a prompt information. In this embodiment, the comparison threshold is M2. The adjustment unit 48 adjusts the comparison threshold M2 stored in the storage unit 44 and obtains an adjustment threshold M3. The adjustment threshold M3 is smaller than the comparison threshold M2, and the general adjustment range is about 10 hours. For example, M2 = 2000 hours and M3 = 1990 hours. The comparing unit 46 of the early warning unit 42 receives the detected value Μ: and adjusts the threshold M3 and compares the detected value M: and the adjusted 1373683 threshold M3. When the detected value Mi is greater than the adjustment threshold M3, the detected value Μ! exceeds the range of the detected value of the lamp use time during normal operation of the projector. That is, when ΜΘΜ3, the prompt information is displayed on the projection screen. The projection prompting system 300 of the present embodiment has the same basic functions as the projection prompting system 100 of the first embodiment, except that the detected objects are different. When the detection time of the bulb in the projector is greater than the adjustment threshold in the warning unit, the prompt information is displayed on the projection screen. • Please refer to FIG. 4, which is a projector prompt system 400 according to a fourth embodiment of the present invention. It is basically the same as the principle of the projector prompting system of the above embodiments, except that the functions of the detecting unit and the early warning unit are different. The projector prompt system 400 includes a detection unit 80 and an early warning unit 82. Preferably, the detecting unit comprises a temperature detecting unit 10, a fan rotation speed detecting unit 20, and a bulb use time detecting unit 40, which are respectively used for detecting the temperature in the projector, the fan rotation speed and the bulb usage time, and obtaining three corresponding detections. value. The early warning unit 82 includes a storage unit 84, a comparison unit «.86, and an adjustment unit 88. The temperature detecting unit 10, the fan rotational speed detecting unit 20, and the bulb use time detecting unit 40 are electrically connected to the comparing unit 86, respectively, and the comparing unit 86, the storage unit 84, and the adjusting unit 88 are electrically connected in sequence. The storage unit 84 of the warning unit 82 stores three comparison thresholds and prompt information corresponding to the temperature in the projector, the fan rotation speed, and the lamp usage time. The adjusting unit adjusts the comparison thresholds to obtain three adjustment thresholds respectively corresponding to the temperature in the projector, the fan rotation speed, and the time taken by the bulb to make 11 1373683. The comparison unit 86 compares the detection value corresponding to any one of the temperature, the fan rotation speed, and the lamp usage time with the adjustment threshold to determine whether each detection value exceeds each detection value range when the projector is in normal operation, when any detection value When the corresponding detection value range of the projector is working normally, the corresponding prompt information is displayed on the projection screen. The projection presentation system 400 of the present embodiment can achieve the effects of the projection presentation system 100 of the first embodiment, the projection presentation system 200 of the second embodiment, and the projection presentation system 300 of the third embodiment. The projection prompt system can detect and display the prompt information to the user for three different abnormal conditions appearing on the projector, further enhancing the sensitivity of the projector prompt system. It can be understood that the detecting unit of the projection prompting system 400 may only include any two detecting units of the temperature detecting unit 10, the fan rotation speed detecting unit 20, and the bulb use time detecting unit 40. Thereby, the effects of the projection presentation system of any two of the projection presentation system 100 of the first embodiment, the projection presentation system 200 of the second embodiment, and the projection presentation system 300 of the third embodiment can be realized. Compared with the prior art, the projector prompting system uses the adjusting unit to adjust the preset comparison threshold in the early warning unit and obtain a corresponding adjustment threshold, and simultaneously perform the detection value of the detecting unit and the corresponding adjustment threshold. The comparison is to determine whether the detected value exceeds the detection range of the projector during normal operation, and when the detected value exceeds the detection range of the projector during normal operation, the prompt information is displayed on the screen. The projector prompting system can display the warning 3683 in advance on the projection screen when the projector is abnormal, so that the latter can know in advance the corresponding measures of the abnormal situation of the projection machine. In summary, the present invention has indeed been applied in accordance with the law. However, the above description is only the preferred embodiment of the present invention, and the equivalent modifications or variations made by the person in the present invention in the spirit of the present invention should be included in the following patent application.
