Abstract

The invention provides a health detection method and for a fan. The method comprises the following steps of: S01, setting the normal cycle, the abnormal detection cycle and the lower limit of the highest speed of the fan; S02, entering the normal cycle in which the fan rotates at a normal speed; S03, detecting the time of the normal operation of the fan; S04, determining whether the normal cycle of the rotation of the fan expires, and if so, entering S05, otherwise, entering S03; S05, entering the abnormal detection cycle in which the fan rotates at the highest speed; S06, determining whether the highest speed of the fan is higher than the set lower limit of the highest speed, and if not, entering S07, otherwise, ending the process; and S07, generating an alarm so that the rotating speed of the fan is restored to a normal speed. The device comprises a setting module, a control module, a detection module, a determination module and an alarm module. With the method and the device disclosed by the invention, the health conditions of the fan can be obtained regularly, so that the satiability of operation of the device is improved.

Description

The health detecting method of fan and device

[technical field]

The invention provides a kind of health detecting method and device, refer to a kind of health detecting method and device of fan especially.

[background technique]

At present, in the equipment such as electronics, communication,, fan generally all is installed, so that equipment can be operated in the normal working temperature scope owing to reasons such as the heating of equipment itself and ambient temperatures.

The fan state direct relation the reliable operation of entire equipment, because the factors such as oxidation, loss and fan self bearing wear of fan, the life-span of fan shortens possibly, and then can cause that temperature raises in the equipment, the life-span of Device element descends, even can cause serious consequence such as equipment operation interruption.

At present, generally equipment fan is adopted two kinds of strategies:

1. when detecting device temperature and exceed normal range (NR), just fan is detected;

2. fan is carried out regular replacing.

In above-mentioned two kinds of strategies,, may cause to cause equipment normally not move, even can cause heavy losses for first kind of strategy; And for second kind of strategy, because not will consider the actual operating state of fan, this can cause two kinds of results: the one, and fan is operational excellence still, changes fan and has just caused the wasting of resources; The 2nd, fan is less than the time limit and just breaks down, and this has just brought hidden danger to device security.

Therefore, the health status of fan is regularly detected and in time make early warning, the reliable operation that improves equipment is just seemed very important.

In view of this, the object of the present invention is to provide a kind of health detecting method and device of fan, utilize this method and apparatus, just can regularly learn the health status of fan, thereby improve operation stability of equipment.

[summary of the invention]

In order to achieve the above object, the invention provides a kind of health detecting method and device of fan, utilize this method and apparatus, just can regularly learn the health status of fan, thereby improve operation stability of equipment.

The health detecting method of fan provided by the invention is characterized in that, this method comprises:

S01, the normal cycle of setting fan, abnormality detection cycle and lower limit the most at a high speed;

S02, enter normal cycle, fan rotates with normal speed;

The uptime of S03, detection fan;

S04, judge whether the normal cycle of fan rotation is full, if, then enter step S05, if not, then enter step S03;

S05, enter the abnormality detection cycle, fan is with high speed rotating;

S06, judge and the lower limit the most at a high speed that the most whether is higher than setting of fan if not, then enter step S07, if then finish;

S07, generation are reported to the police, and rotation speed of the fan reverts to normal speed.

The health detection device of fan provided by the invention, this installs based on said method, it is characterized in that, and this device comprises:

Setting module is used for setting normal cycle, abnormality detection cycle and the lower limit the most at a high speed of the fan of above-mentioned steps S01;

Control module, being used for according to fan is that the different situations that enter normal cycle or enter the abnormality detection cycle are controlled fan with the normal speed rotation or with high speed rotating;

Testing module is used to receive normal cycle and abnormality detection cycle that above-mentioned setting module is set, and the control that receives above-mentioned control module detects fan uptime or misoperation time, and testing result is fed back to above-mentioned control module;

Judge module is used to receive the lower limit the most at a high speed that above-mentioned setting module is set, and receive fan in abnormality detection cycle that runs on of above-mentioned control module output the most at a high speed, and will be above-mentioned the most at a high speed lower limit and the above-mentioned high speed of fan make comparisons;

Alarm module is used for sending alarm signal to remind the user when fan above-mentioned is lower than the most at a high speed above-mentioned the most at a high speed lower limit.

Preferably, the alarm signal that sends of described alarm module can be one or more in voice, the tinkle of bells, short message and the flashing light.

Compared to prior art, utilize the health detecting method and the device of fan of the present invention, just can regularly learn the health status of fan, thereby improve operation stability of equipment.

For purpose of the present invention, structure characteristics and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:

[description of drawings]

Fig. 1 illustrates the flow chart into a preferred embodiment of the health detecting method of fan of the present invention.

Fig. 2 illustrates and is the structured flowchart based on the health detection device of the fan of method among Fig. 1.

[embodiment]

Seeing also Fig. 1, is the flow chart of health monitor method one preferred embodiment of fan of the present invention, and this method comprises:

Step S01, the normal cycle of setting fan, abnormality detection cycle and lower limit the most at a high speed;

Step S02, enter normal cycle, fan rotates with normal speed;

The uptime of step S03, detection fan;

Step S04, judge whether the normal cycle of fan rotation is full, if, then enter step S05, if not, then enter step S03;

Step S05, enter the abnormality detection cycle, fan is with high speed rotating;

Step S06, judge and the lower limit the most at a high speed that the most whether is higher than setting of fan if not, then enter step S07, if then finish;

Step S07, generation are reported to the police, and rotation speed of the fan reverts to normal speed.

One of fan is taken turns health detection and is finished.

The next round of fan detects and can carry out automatically according to above-mentioned testing process, and this next round detects and can detect according to the abnormality detection cycle shorter than the above-mentioned abnormality detection cycle.

Seeing also Fig. 2, is the structured flowchart that the present invention is based on flow chart shown in Figure 1.The main composition module of the health measuring function part of this block representation fan comprises: setting module 1, control module 2, testing module 3, judge module 4 and alarm module 5.
