Embodiment 1

[0023] For the fan system, a speed sensor is installed on the shaft of the fan (or a rotating shaft that rotates synchronously with the shaft of the fan), and the speed of the fan is detected by the speed sensor. The speed sensor uses encoders, hall sensors, proximity switches and other types of equipment to count the number of rotations of the fan shaft through pulses, and then calculate the speed according to the time used. The speed sensor can directly output counting pulses.

[0024] In this embodiment, the lubricating pump is used as the lubricating equipment to implement control (as other implementations, equipment such as nozzles may also be used).

[0025] like figure 1 As shown, in the embodiment of the method of the present invention, a number of turns counter (software counter) is set with an initial value of 0, which is used to accumulate the number of turns of the fan bearing, and perform lubrication when the accumulation reaches a certain set value operate. Th...

Embodiment 2

[0035] This embodiment is an improvement on the basis of Embodiment 1, as figure 1 As shown, the control of grease injection takes a certain amount of time in the main program flow, so the figure 1 Transform the program flow of the program, and form the control of fat injection into an independent thread, process or interrupt service program, so as to avoid increasing the time of the main program process.

[0036] Specifically, such as figure 2 As described, the method steps of this embodiment are as follows:

[0037] Step 2.1, accumulating the number of turns counter according to the counting pulses output by the speed sensor, and reading the count value of the turns counter.

[0038] Step 2.2, judging whether the count value of the lap counter reaches the set value, if not, continue counting;

[0039] In step 2.3, if the set value is reached, the grease injection operation flag is set, and the lap counter is reset at the same time.

Abstract

The invention relates to a lubrication control method and device based on turn number control. The lubrication control method comprises the steps of counting a count pulse, output by a rotation speedsensor, by using a turn number counter; judging whether a count value of the turn number counter reaches a set value or not; if the count value of the turn number counter does not reach the set value,continuing to count; and if the count value of the turn number counter reaches the set value, starting lubrication operation; and resetting the turn number counter. According to the lubrication control method and device based on turn number control, the problem of poor lubrication effect of the prior art can be soled, and the lubrication effect can be greatly improved.

Description

technical field [0001] The invention relates to the field of lubrication control, in particular to a lubrication control method and device based on circle number control. Background technique [0002] In the prior art, the control strategy of the lubrication system is formulated based on time. [0003] For example, in an automatically controlled lubrication system, when a fixed time interval is reached, the lubrication equipment is automatically turned on to inject lubricant (including grease injection using a lubrication pump, lubrication nozzle, etc.) for lubrication. [0004] The disadvantage of this control method is that the time interval (hereinafter referred to as the lubrication interval) is fixed, and the operation of mechanical equipment is not necessarily regular, sometimes in a state of high-speed and heavy-load operation, and sometimes in a low-speed and small-load operation state. This makes: if the lubrication interval is too long, it will easily lead to unde...
