Embodiment
Elaborate below in conjunction with the mode of execution of accompanying drawing to a kind of ceiling fan monitoring device of the utility model.
Referring to Fig. 1, a kind of ceiling fan monitoring device comprises casing 11 and circuit board 12, at the interior circuit board 12 that arranges of described casing 11.Described circuit board 12 comprises single-chip microcomputer 13 and storage 14.Described single-chip microcomputer 13 is electrically connected to infrared sensor 15.In the present embodiment, described single-chip microcomputer 13 is MSC-51 type single-chip microcomputer, has that reliability is high, cost is low, circuit is simple, advantage easy to use.
Described infrared sensor 15 be arranged on ceiling fan 16 directly over, near the suspension rod 17 of ceiling fan 16, and be close to body of wall, like this, can prevent that not only ceiling fan 16 from rocking the damage to infrared sensor, and can improve the degree of accuracy that judges the ceiling fan operating condition.
In the present embodiment, described ceiling fan monitoring device also comprises the warning device (not shown), and described warning device is electrically connected to single-chip microcomputer.Described warning device can be a buzzer 18, and described buzzer 18 is arranged on the outer surface of casing 11, is electrically connected to described single-chip microcomputer 13.Described warning device also can be a light emitting diode 19, and described light emitting diode 19 is arranged on the outer surface of casing 11, is electrically connected to described single-chip microcomputer 13.
Described ceiling fan monitoring device also comprises battery 20, and described battery 20 is arranged on casing 11 inner bottom parts, is electrically connected to described single-chip microcomputer 13, infrared sensor 15, buzzer 18 and light emitting diode 19 respectively.Described battery 20 adopts the battery of 6V, is convenient to the replacing of battery.
The working principle of a kind of ceiling fan monitoring device of the utility model is:
The casing 11 of a kind of ceiling fan monitoring device of the utility model can be arranged on ceiling fan 16 switches near, infrared sensor 15 be arranged on ceiling fan 16 directly over, near the suspension rod 17 of ceiling fan 16, and be close to body of wall.When ceiling fan 16 operation, after infrared sensor 15 receives the Monitoring instruction that single-chip microcomputer 13 regularly sends, the emission infrared rays, when infrared rays (for example runs into shield, suspension rod 17) time, infrared rays is folded back, so infrared sensor can record the time difference between the infrared rays sending and receiving.According to the distance between the position of the position of infrared sensor 15 and ceiling fan 16, the time in the time of can calculating ceiling fan 16 and do not rock.Suppose that this time is T second (s), in order to improve the degree of accuracy of judgement, normal error is (T+W) second (s).This time threshold is stored in storage 14.The position that is placed in different positions, ceiling fan 16 due to infrared sensor 15 is also different, and therefore, the time threshold that presets is also different, needs to adjust according to actual conditions.
Obtain the time difference of send-receive when infrared rays sensor 15 after, this time difference is sent to single-chip microcomputer 13, single-chip microcomputer 13 calls the time threshold that is stored in storage 14, compare, if the time difference that records is during greater than time threshold, single-chip microcomputer 13 can send alarm signals to buzzer 18, to do listening warning, or single-chip microcomputer 13 sends a signal to light emitting diode 19, to make visual alarm.
Shown in Figure 3, after single-chip microcomputer 13 receives the time difference that infrared senor 15 monitors, compare with the time threshold values that presets, if described time difference is greater than the time that presets during threshold values, single-chip microcomputer 13 sends an alarm signal to buzzer 18, buzzer 18 pipes after receiving alarm signal, or single-chip microcomputer 13 sends a signal to light emitting diode 19, light emitting diode 19 flickering display after receiving alarm signal.Described single-chip microcomputer 13 is connected with battery 20, and battery 20 provides electric energy to single-chip microcomputer 13.
The above is only preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model structure; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
