Detailed Description
The invention discloses a barrier gate spring fault early warning method, which can indirectly acquire the lifting state of a gate rod by reading the motor operation data of a barrier gate motor and comparing the motor operation data with standard data, and after a spring fails, the lifting state of the gate rod is seriously changed, so that whether the spring fails or not can be quickly acquired by comparing the motor operation data, and the problems in the prior art are further solved.
The technical solutions in the embodiments of the present invention are described in detail and clearly with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. Referring to fig. 1, a first embodiment of a method for early warning a failure of a barrier spring according to the present invention includes:
s1: reading motor operation data of a barrier motor within the time range from gate opening to gate closing of the barrier;
first, in the barrier, a barrier motor controls a main shaft through a multi-link structure, and then drives a gate rod to rotate. Therefore, the rotation condition of the brake bar can be obtained by reading the motor operation data of the barrier motor, for example, the output torque of the barrier motor, namely the stress condition of the brake bar, can be obtained by reading the current value of the barrier motor, and the lifting speed of the brake bar can be obtained by reading the rotating speed value of the barrier motor and converting the rotating speed value into the speed value of the brake bar.
S2: generating a data chart between time and motor operation data;
the data chart may include tables, discrete point data, and curves.
S3: obtaining comparison data from the data chart for comparison with standard data;
it should be noted that not all of the data graphs are useful data, for example, when the gate detects that the vehicle is always under the gate rod and cannot drop the rod, a large segment of invalid data is generated, so data capable of reflecting the working state of the gate rod, for example, data such as the peak speed of the gate rod or the peak current value of the gate motor, needs to be extracted from the data graphs, and then the obtained valid data is compared with the standard data.
S4: reading standard data obtained when a barrier gate is in a normal state, and comparing the comparison data with the standard data to obtain a comparison result;
s5: and sending out a spring state abnormity alarm according to the comparison result.
The spring state abnormality mainly has three conditions including over-tightening of the spring, over-loosening of the spring and breakage of the spring, and the three conditions affect the operation of the barrier gate, so that a user needs to be informed in time. That is, the abnormal alarm of the spring state can comprise an over-tight alarm of the spring, an over-loose alarm of the spring and a fracture alarm of the spring; the sending of the spring state abnormality alarm may specifically include sending one or more of a visual alarm, an audio alarm and a remote alarm, wherein the visual alarm includes displaying alarm content through at least one of a card, a display screen, a display lamp or a nixie tube, the audio alarm includes alarming through a speaker and/or a buzzer, and the remote alarm includes remotely sending an alarm through a communication network and/or a wireless communication technology.
The invention provides a barrier gate spring fault early warning method, which comprises the steps of firstly reading motor operation data of a barrier gate motor in the time range from gate opening to gate closing of a barrier gate; then generating a data chart between time and motor operation data; then obtaining comparison data for comparison with standard data from the data chart; reading standard data obtained when the barrier gate is in a normal state, and then comparing the comparison data with the standard data to obtain a comparison result; and finally, sending out a spring state abnormity alarm according to the comparison result. By reading the motor operation data of the barrier gate motor and comparing the motor operation data with standard data, the barrier gate spring fault early warning method can indirectly know the lifting state of the gate rod, and the lifting state of the gate rod can be seriously changed when the spring is in the conditions of over-tightness, over-looseness or fracture, so that the state of the spring can be quickly known by comparing the motor operation data, and the problems in the prior art are further solved.
Referring to fig. 2 and 3, in the embodiment, the motor operation data is a current value, and it should be noted that the current value of the barrier motor is a parameter reflecting the output torque of the barrier motor, that is, the stress condition of the barrier rod.
Preferably, the first and second liquid crystal materials are,
the motor operation data is a current value, and the current value of the barrier gate motor in the time range from gate opening to gate closing of the barrier gate is read;
generating a data chart between time and current value;
the comparison data is a peak current value, and the peak current value of the barrier gate motor is read from the data chart;
the standard data is a standard peak current value, a standard peak current value obtained when the barrier gate is in a normal state is read, and the peak current value is compared with the standard peak current value to obtain a comparison result;
and sending out a spring state abnormity alarm according to the comparison result.
Preferably, the first and second liquid crystal materials are,
the peak current value comprises a switching-on peak current value and a switching-off peak current value;
the standard peak current value comprises a standard switching-on peak current value and a standard switching-off peak current value, the switching-on peak current value is compared with the standard switching-off peak current value to obtain a switching-on comparison result, and the switching-off peak current value is compared with the standard switching-off peak current value to obtain a switching-off comparison result;
and carrying out error deduction on the switching-off comparison result and the switching-on comparison result, if the switching-on comparison result is that the switching-on peak current value is smaller and the switching-off comparison result is that the switching-on peak current value is larger, determining that the spring is too tight, if the switching-on comparison result is that the switching-on peak current value is larger and the switching-off comparison result is that the switching-on peak current value is smaller, determining that the spring is too loose, and if the switching-on comparison result is that the switching-on peak current value reaches the breaking value of the switching-on spring and the switching-off comparison result is that the switching-off peak current value reaches the breaking value of the switching-off spring, determining that the spring is broken.
Preferably, the first and second liquid crystal materials are,
the error value range is 0-200 milliamperes.
Referring to fig. 2 and fig. 3, it can be known from an observation of fig. 2 that the current value of the barrier motor includes a gate-opening peak current value during a gate-opening process of the barrier and a gate-closing peak current value during a gate-closing process of the barrier, where the gate-opening peak current value is between 2200 ma and 2400ma, and the gate-closing peak current value is between 2700 ma and 2900 ma; after the spring is broken, because the elastic force of the spring is suddenly reduced, the barrier motor can rotate the barrier only by outputting larger torsion when the barrier is opened, namely, the opening peak current value of the barrier motor is increased, and when the barrier is closed, the barrier motor can rotate the barrier by outputting smaller torsion, namely, the closing peak current value of the barrier motor is decreased, and by observing the graph 3, the opening peak current value is 4200-4400 ma and the closing peak current value is 2300-2500 ma when the barrier is in the spring breaking state; that is, the current value, especially the opening peak current value, is greatly changed before and after the barrier is in the state of spring breakage, so the state of the spring in the barrier can be known by comparing the opening peak current values. It should be noted that the peak current value may be a data point or a value range, and is not limited herein. The above describes the judgment and comparison process of spring breakage, when the spring is in an over-loose state, the opening peak current value is larger than the opening standard peak current value and the closing peak current value is smaller than the closing standard peak current value, wherein the difference value between the opening peak current value and the opening standard peak current value depends on the tightness of the spring, and at this time, a user should be informed to tighten the spring; on the contrary, when the spring is in an over-tight state, the opening peak current value is smaller than the opening standard peak current value and the closing peak current value is larger than the closing standard peak current value, and the user should be informed to adjust the spring to be loose.
It should be noted that, due to various reasons, for example, normal wear of the multi-link structure and fluctuation of the input current of the barrier motor, even if the barrier is in a normal state, the rotation speed of the gate lever or the current value of the barrier motor will deviate from the standard data, so that the read current value of the barrier motor in the time range from opening to closing of the barrier can be subjected to error processing, for example, the current value outside the error range can be used as an effective value, and the error value range can be specifically 0 to 200 ma.
Preferably, the first and second liquid crystal materials are,
the data chart is a relation curve of time and a current value, and the relation curve is named as a relation curve A;
the comparison data are a relationship curve of effective current of the gate during the gate opening process of the gate and a relationship curve of effective current of the gate during the gate closing process of the gate in the relationship curve A;
the standard data is a standard current relation curve of the gate opening in the gate opening process of the barrier gate and a standard current relation curve of the gate closing in the gate closing process of the barrier gate;
and comparing the comparison data with the standard data to obtain a comparison result, and fitting the opening effective current relation curve and the closing effective current relation curve with the opening standard current relation curve and the closing standard current relation curve to obtain a fitting degree result.
It should be noted that, in addition to directly comparing the peak current value, a comparison result can be obtained by means of curve fitting, when the barrier gate is in a normal state, the relationship curve of the effective opening current and the relationship curve of the effective closing current of the barrier gate motor are basically consistent with the relationship curve of the standard opening current and the relationship curve of the standard closing current, and even if there is a deviation, a highly fitted result can be obtained by means of curve fitting; if the spring is in the condition of being too loose, too tight or broken, a great difference point can be found between the effective switching-on current relation curve and the effective switching-off current relation curve of the barrier gate motor and the standard switching-off current relation curve, a result with poor fitting degree can be obtained by curve fitting, and whether the barrier gate spring is broken or not can be obtained according to the fitting degree result.
Referring to fig. 4 and 5, in the embodiment, the motor operation data is a rotation speed value, and it should be noted that the rotation speed value of the barrier motor reflects the speed condition of the barrier rod, because the opening and closing speed values of the barrier rod are intuitive, the rotation speed value of the barrier motor is converted into more intuitive opening and closing speed values of the barrier rod for displaying.
Preferably, the first and second liquid crystal materials are,
the motor operation data is a rotating speed value, and the rotating speed value of the barrier gate motor in the time range from gate opening to gate closing is read;
generating a data chart between time and a rotating speed value;
the comparison data is a peak value of rotation speed, and the peak value of rotation speed of the barrier gate motor is read from the data chart;
the standard data is a standard peak value of rotation speed, the standard peak value of rotation speed obtained when the barrier gate is in a normal state is read, and the peak value of rotation speed is compared with the standard peak value of rotation speed to obtain a comparison result;
and sending out a spring state abnormity alarm according to the comparison result.
Referring to fig. 4 and 5, it can be known from the observation of fig. 4 that the bar speed values include a bar opening speed value during the bar opening process and a bar closing speed value during the bar closing process when the barrier gate is in a normal state, wherein the bar opening speed value is between 1350rpm and 1500rpm, the bar closing speed value is between 1350rpm and 1500rpm, that is, the bar opening speed and the bar closing speed are relatively uniform; by observing fig. 5, it can be known that when the barrier gate is in a spring fracture state, the brake opening speed value of the brake lever is between 1200 rpm and 1350rpm, and the brake closing speed value of the brake lever is between 1600 rpm and 1750rpm, and the situation that the speed change of the brake opening and the brake closing of the brake lever is large but shaking exists can be found; the state of the spring in the barrier can be known by directly comparing the speed change condition of the brake lever. It should be noted that the peak rotational speed value may be a data point or a numerical range, and is not limited herein. The judgment and comparison process of the spring breakage is described, and when the spring is in an over-loose state, a result similar to the spring breakage is obtained; conversely, when the spring is over-tightened, a result opposite to the spring breakage is obtained, and the user should be notified to adjust the spring loose.
Preferably, the first and second liquid crystal materials are,
the data chart is a relation curve of time and a rotating speed value, and the relation curve is named as a relation curve B;

and comparing the comparison data with the standard data to obtain a comparison result, and fitting the opening effective rotating speed relation curve and the closing effective rotating speed relation curve with the opening standard rotating speed relation curve and the closing standard rotating speed relation curve to obtain a fitting degree result.
It should be noted that, besides directly comparing the peak value of the rotation speed, the comparison result can be obtained by curve fitting, when the barrier gate is in normal state, the relationship curve of the effective opening and closing rotation speeds of the barrier gate motor is basically consistent with the relationship curve of the standard opening and closing rotation speeds, even if there is deviation, the result of high fitting can be obtained by curve fitting; if the spring is broken, a great difference point between the effective opening speed relation curve and the effective closing speed relation curve of the barrier motor and the standard opening speed relation curve and the standard closing speed relation curve can be found, a result with poor fitting degree can be obtained by curve fitting, and whether the barrier spring is broken or not can be known according to the fitting degree result.
In the embodiment, the motor operation data is a current value and a rotation speed value, and it should be noted that the rotation speed value of the barrier motor reflects the speed condition of the barrier rod, and because the opening and closing speed values of the barrier rod are intuitive, the rotation speed value of the barrier motor is converted into more intuitive opening and closing speed values of the barrier rod for displaying.
