[0005] The existing rain detection device, if it detects rainfall, it will cause loss to the lubrication of the mechanical system, which will cause unnecessary lubrication operations (for example, the light rain season in the Jiangnan area of our country will not actually cause loss to the lubrication system), and will cause damage to the lubrication system. Indirectly increase the maintenance cost of outdoor escalators
[0006] The existing rain detection device only detects whether there is rain before implementing the compensation lubrication action, which may affect the subsequent compensation lubrication effect under certain circumstances

Embodiment 1
[0038] like figure 1 As shown, the open-air passenger conveying equipment lubrication system includes a rainfall detecting device, a control device and a lubricating device:
[0039] The rainfall detecting device outputs a rainwater pressure detection signal to the control device according to the rainwater pressure X currently landed to the detecting plate;
[0040] The detection plate of the rainfall detecting device is open;
[0041] The control device, such as figure 2 As shown, control the lubricating device as follows:
[0042] Step one .i = 0;
[0043] Step 2. If the rain water pressure X in the rain water pressure detection signal reaches the first rainfall intensity threshold, proceed to step three; if the rain water pressure X in the rainpress pressure detection signal continues to be less than the first rainfall intensity threshold, press the default lubrication mode Control the work of lubrication device;
[0044] Step 3. If cases 1, then control the lubrication device ...
Embodiment 2
[0048] The open-air passenger conveying equipment lubrication system based on the first example, the control device controls the work of the lubrication device. In step three, if the case 2 is satisfied, the lubricating device is controlled according to the water lubrication mode, and step one;
[0049] The case 2 refers to: In the sampling period T, the rainwater pressure X in the rainwater pressure detection signal reaches the sampling period T after the first rainfall intensity threshold, does not satisfy the case 1, and the accumulated rainfall K is greater than or equal to the single time period Rainstorm threshold, The rainwater pressure X in the rain water pressure detection signal is equal to 0 times at a time equal to the first rainfall intensity threshold.
Embodiment 3
[0051] The open-air passenger conveying equipment lubrication system is based on the second embodiment, the control device controls the work of the lubrication device, in step three:
[0052] If case 1 is satisfied, the lubrication device is controlled by the heavy rain lubrication mode, then clear the recorded single accumulated rainfall Ks, proceed to step one;
[0053] If case 2, the lubricating device is controlled according to the water lubrication mode, and then clear the single cumulative rainfall Ks of the record, step one;
[0054] If case 3 is satisfied, the lubricating device is controlled according to the water lubrication mode, and then clear the recorded single accumulated rainfall Ks, proceed to step one;
[0055] The case 3 refers to: case 1 and the case 2 is not satisfied, and the rainwater pressure X in the rain water pressure detection signal reaches the first rainfall intensity threshold, the current rainwater pressure detection signal X is smaller than the fir...

Abstract
The invention discloses a lubricationsystem for open-air passenger conveying equipment, which includes a rainfall detection device, a control device and a lubrication device; the rain detection device outputs a rainwater pressure detectionsignal to the control device according to the current rainwater pressure falling on its detection plate; The control device, within the sampling period after the rainwater pressure X in the rainwater pressure detectionsignal reaches the first rainfall intensity threshold for the first time, if the rainwater pressure in the rainwater pressure detectionsignal reaches the second higher rainfall intensity threshold, or the rainwater pressure If the variation reaches the rainfall intensity variation threshold, or the rainwater pressure change rate reaches the rainfall intensity variation rate threshold, the lubricating device is controlled to work in the rainstorm lubrication mode. The invention can avoid the misjudgment of the system caused by the rain signal attached to the detection surface of the detection device by the rainwater, can improve the lubrication accuracy, and can ensure the lubrication of the mechanical system of the open-air passenger conveying equipment when it is strongly impacted by the rainwater.
Description
Technical field [0001] The present invention relates to elevator techniques, and more particularly to an open-air passenger conveying equipment lubrication system. Background technique [0002] The escalator is typically obliquely, and the pedestrians automatically walk on one end of the escalator, they will be automatically taken to the other end of the escalator. At present, more and more escalators are installed outdoors, which are maintained for regular lubrication by the weather. The traditional escalator uses a manner that initiates lubrication and interval lubrication, starting lubrication is to control the chain by the start signal of the escalator to control the oil pump to lubricate the chain, and the interval lubrication is a time relay or program software to set a time, when an escalator The control oil pump lubricates the chain when running to set time. Starting lubrication does not consider the weather influence during maintenance, the chain of the conveyor belt no ...
