Abstract
The invention discloses a fan detection system of a jacquard. The fan detection system comprises a first comparator, and an eighth antenna of the first comparator is connected with the 0.2V voltage; a first capacitor is connected to a ninth antenna of the first comparator and is connected with a ground wire; and a first resistor is connected to the positive input end of the first comparator. According to the technical scheme, whether fans rotate normally or not can be automatically detected in time, people do not need to specially inspect whether the fans fail or not one by one, and manpower and material resources are saved.
Description
Technical field
The present invention relates to the automatical control system of jacquard machine, especially relate to a kind of fan detection system of jacquard machine.
Background technique
At present, electronic jacquard machine is owing to employing a large amount of electromagnet, heating value is quite large, so all adopt fan cooling, but existing fan cooling has the following disadvantages: first fan has been broken and do not known, cause the electromagnet of jacquard machine overheated, electromagnet is generally plastic casing, when the temperature of electromagnet acquires a certain degree, plastic casing will melt.Secondly large problem is caused in order to prevent fan from damaging, the person's of sending someone running check, wasting manpower and material resources.
Summary of the invention
The object of the invention is the problem solving above-mentioned proposition, a kind of fan detection system that can detect a kind of jacquard machine of fan temperature is provided.
The object of the invention is to realize as follows: a kind of fan detection system of jacquard machine, comprise the first comparator, 8th feeler of described first comparator connects the voltage of 0.2V, 9th feeler of described first comparator connects the first electric capacity, described first electric capacity connects ground wire, and the first resistance is connected to the positive input terminal of the first comparator.
Further optimized project is, the fan detection system of above-mentioned a kind of jacquard machine, and the 14th feeler of described first comparator is connected with the 3rd resistance, is connected with pull-up resistor between the output terminal of the 14th feeler of described first comparator and described 3rd resistance.
Further optimized project is, the fan detection system of above-mentioned a kind of jacquard machine, the output terminal of described 3rd resistance is connected with the positive input terminal of the second comparator, and the second electric capacity and the 4th resistor coupled in parallel are on the branch road of the positive input terminal of described 3rd resistance and the second comparator.
Further optimized project is, the fan detection system of above-mentioned a kind of jacquard machine, and the negative input end of described second comparator connects voltage 1V.
Advantage of the present invention: not only automatically whether the moment to detect fan running normal for technological scheme of the present invention, and people need not be had to go to inspect fan in turn specially whether have fault, saved manpower and materials.
Accompanying drawing explanation
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation, wherein
Fig. 1 is electrical block diagram of the present invention.
Embodiment:
As shown in Figure 1, a kind of fan detection system of jacquard machine, comprise the first comparator, 8th feeler of described first comparator connects the voltage of 0.2V, 9th feeler of described first comparator connects the first electric capacity C1, described first electric capacity connects ground wire, and the first resistance R1 is connected to the positive input terminal of the first comparator.14th feeler of described first comparator is connected with the 3rd resistance R3, between the output terminal of the 14th feeler of described first comparator and described 3rd resistance R3, is connected with pull-up resistor R2.The output terminal of described 3rd resistance R3 is connected with the positive input terminal of the second comparator, and the second electric capacity C2 and the 4th resistance R4 is connected in parallel on the branch road of the positive input terminal of described 3rd resistance R3 and the second comparator.The negative input end of described second comparator connects voltage 1V.
Above-described specific embodiment; object of the present invention, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
