In order to solve the technical problem, the invention provides an elevator running speed measuring method and system. Because the qth time difference is calculated by utilizing the qth stopping time and the qth starting time, when Q is greater than the counting times Q, the difference value between the 2 nd to the qth time difference and the 1 st time difference and the difference value between the 2 nd to the qth floor number and the 1 st floor number are respectively calculated, the running speeds of a plurality of elevators are obtained by calculation, the average running speed of the elevators is obtained, and the error is reduced.

Fig. 1 is a schematic flow chart of an elevator running speed measuring method according to a first embodiment of the present invention. Specifically, the method for measuring the running speed of the elevator comprises the following steps:
step 1: when the elevator is started at the starting floor, recording the q-th starting time of the elevator, and when the elevator stops running at the q-th terminal floor, recording the q-th stopping time and the q-th floor number of the elevator, wherein the initial value of q is 1, and the q-th floor number is not equal to any one of the 1 st floor number to the q-1 st floor number;
and 4, if Q is larger than or equal to Q, respectively calculating the difference value between the 2 nd to Q th time difference and the 1 st time difference and the difference value between the 2 nd to Q th floor number and the 1 st floor number, calculating the running speeds of a plurality of elevators, and calculating the running average speed of the elevators.
Further, the specific steps of step 4 include:
respectively calculating the difference between the 2 nd to Q th time difference and the 1 st time difference and the difference between the 2 nd to Q th floor number and the 1 st floor number according to the following formulas, calculating the running speeds of a plurality of elevators, and solving the running average speed of the elevators:
(Tp-T1)v＝(|Np-N1|)h
wherein, TpDenotes the p-th time difference, T1Representing the 1 st time difference, v representing the running speed of the elevator, NpIndicates the p-th floor number, N1And (3) representing the number 1 of floors, and h representing the height data of the floors, wherein the value of p is any one of 2 to Q.
Further, the 1 st to Q th starting time represent the time when the display arrow of the upward movement of the elevator is lightened, or the time when the starting signal of the elevator is taken out from the elevator communication port.
Further, the 1 st to the Q th stop time represent the time when the display arrow of the upward movement of the elevator is extinguished or the time when the stop signal of the elevator is taken out from the elevator communication port.
Further, the differences between the 2 nd to the Q th terminal floors and the 1 st terminal floor are all greater than 1 floor.
It should be noted that the conventional elevator operation process includes four processes of elevator starting acceleration, uniform speed operation, braking deceleration, crawling and the like, the running time of the conventional elevator operation process is shown in fig. 2, and fig. 2 is a schematic diagram of the running time of the elevator provided by the first embodiment of the present invention. Wherein:
(1)t1to initiate the acceleration time. At the moment, the traction motor drives the elevator car to accelerate at a high acceleration.
(2)t2Is the uniform motion time. The speed is now related to the rated speed of the hoisting motor and is the running speed v of the elevator to be measured in the invention.
(3)t3Is the brake deceleration time. At this time, the traction motor decelerates with braking.
(4)t4Is the crawl time. For comfort, the elevator approaches the stopping floor at a creeping speed.
To sum up, elevator driving time T is:
T＝t1+t2+t3+t4 (1)
the running distance composition of the corresponding elevator is shown in fig. 3, and fig. 3 is a schematic diagram of the running distance of the elevator provided by the first embodiment of the invention. Wherein:
(1)h1to initiate the acceleration distance. Typically less than one floor.
(2)h2Is a uniform motion distance. This is a major part of the operation of the elevator.
(3)h3Is the braking deceleration distance. Typically less than one floor.
(4)h4Is the creep distance. Typically less than 2 meters.
To sum up, elevator driving distance H does:
H＝h1+h2+h3+h4 (2)
the change of the elevator running floor number respectively corresponds to the floor number of the elevator from starting to stopping, the floor number of the starting floor is respectively represented by N, and N1The number of floors (here, the 1 st floor) representing the terminal floor, the floor height is H, and the traveling distance of the elevator is H1＝(|N1-N |) h, corresponding to a driving time T1. The formula about the uniform speed running of the elevator can be calculated by using the formula (2) and the formula (1):
(T1-t1-t3-t4)v＝(|N1-N|)h-h1-h3-h4 (3)
wherein, t1、t3、t4Or h1、h3、h4Are difficult to measure accurately, thereby bringing great difficulty to the calculation of the running speed v of the elevator.
On this basis, the statistical number is exemplified as 2. Testing the traveling distance of the other section of the elevator, wherein the number of the corresponding initial floors is N, and the number of the corresponding stopping floors is N2(number 2 floor here), the traveling distance of the elevator is H2＝(|N2-N |) h, corresponding to a driving time T2And then:
(T2-t1-t3-t4)v＝(|N2-N|)h-h1-h3-h4 (4)
starting acceleration time t of elevator under different running distances but same environmental conditions1Braking deceleration time t3And a creep time t4And corresponding start-up acceleration distance h1Braking deceleration distance h3And a creeping distance h4Are all invariant, so equation (3) is subtracted from equation (4) to yield:
(T2-T1)v＝(|N2-N1|)h (5)
the running speed v of the elevator can be easily calculated according to the formula (5).
It should be noted that when the preset statistical number is 2, if the running speed v of the elevator is calculated by using the formula (5), the floor height data must be acquired. When the preset statistical times are more than 2 and the floor height data can be obtained, the formula (T) can be usedp-T1)v＝(|Np-N1And l) h (the principle is the same as that of the formula (5) and comprises the formula (5)), taking the value of p as any one of 2 to Q, calculating the running speeds of Q-1 elevators, removing the running speed with larger error in the running speeds of the Q-1 elevators, and calculating the running average speed of the elevator by using the rest running speed.
It should be noted that, if the floor height data cannot be directly obtained, the running speed of the elevator cannot be calculated by using the formula (5), at this time, a formula needs to be solved in a simultaneous manner, and the number of times of statistics needs to be greater than 2.
Specifically, the statistical frequency is taken as 3. On the basis of the measured formula (5), measuring the travel distance of another section of the elevator, wherein the floor number of the starting floor is N, and the floor number of the stopping floor is N3(number 3 of floors) in the elevator, the traveling distance of the elevator is H3＝(|N3-N |) h, corresponding to a driving time T3Then, there are:
(T3-t1-t3-t4)v＝(|N3-N|)h-h1-h3-h4 (6)
subtracting equation (3) from equation (6) yields:
(T3-T1)v＝(|N3-N1|)h (7)
a linear equation of two is formed by the formula (5) and the formula (7), and the floor height data h and the running speed v of the elevator can be indirectly calculated.
It should be noted that when the predetermined statistical number is greater than or equal to 3 and the floor height data cannot be obtained, the formula (T) is usedp-T1)v＝(|Np-N1And i) h, taking the value of p as any one of 2 to Q to obtain Q-1 calculation formulas, combining any two calculation formulas to obtain the running speed of the elevator by calculation, removing the running speed with larger error, and calculating the running average speed of the elevator by using the rest running speed.
In addition, in order to avoid the interference of the user taking the elevator during the elevator running, the idle time of the elevator needs to be selected for measurement. And the differences between the 2 nd to the Q th terminal floors and the 1 st terminal floor are all larger than 1 floor. The reason is that the total distance of the elevator starting, braking and crawling is between 1-2 floors, if the difference is less than or equal to 1, the elevator may not be started and the braking is started at a constant speed, and the measured running error is large. Starting the elevator, starting timing, and if the elevator is on site, indicating the lighting time of the display arrow of the upward elevator by the 1 st to the Q-th starting time and indicating the extinguishing time of the display arrow of the upward elevator by the 1 st to the Q-th stopping time; if not, the monitoring system can be utilized, the 1 st to Q th starting time is the time for sending the starting signal for taking out the elevator from the elevator communication port, and the 1 st to Q th stopping time is the time for sending the stopping signal for taking out the elevator from the elevator communication port. If the floors have the conditions similar to fire-fighting floors (namely, the heights of the floors are not consistent), the fire-fighting floors are avoided in the measurement, and the floors with the consistent heights of the floors are selected, so that the measurement result is more accurate.
Further, the invention has the following beneficial effects:
(1) the test is simple. The running speed of the elevator can be calculated by measuring the running time of the elevator without the need of parameters such as gear ratio, motor diameter, rotating speed and the like in the method given by the GB/T10059-1997 standard.
(2) The test is quick. The complex processes of starting, braking, crawling and the like in the running process of the elevator are eliminated, and the running speed of the elevator can be quickly calculated by utilizing a uniform motion formula.
(3) The long-term monitoring of the elevator is facilitated. By adopting the method of the invention, the operation of the elevator can be detected for a long time, and particularly, the operation speed of the elevator can be monitored for a long time through a monitoring system. Any kind of ageing or malfunction of the elevator can be reflected in a change of the operating speed of the elevator. If the speed change of the elevator exceeds the range of international regulations, the elevator monitoring system can give an alarm to an elevator maintenance unit to carry out maintenance, and the safe operation of the elevator is ensured.
The use safety of the elevator is closely related to the life and property safety of residents. The monitoring of the operation data of the elevator is a powerful means for improving the safe operation level of the elevator and standardizing the market, and has important social significance for improving the quality and the service level of the elevator and reducing accident potential.
