Referring to FIG. 1, Fig. 1 is a kind of implementation flow chart of the method for controlling security of subway shield door in the present invention, the party
Method the following steps are included:
S101: in shield door from during starting position normal movement to stop position, acquisition shield door is moved to respectively
The corresponding current value of driving motor when a predeterminated position, and as one group of sample data.
It should be pointed out that needing to carry out the acquisition of sample data in the state that shield door operates normally.Shield door
It operates normally, refers to that shield door is run according to scheduled rate curve.It can be found in Fig. 2, showing shield door just in Fig. 2
Often door closing speed curve when operation, abscissa is move distance of the shield door in door closing procedure, namely has corresponded to shield door
The locating different location in door closing procedure.When moving to different positions, the movement velocity of shield door is likely to be at acceleration, even
The case where speed and deceleration.And it should be noted that shield door door closing speed curve usually it is different with enabling rate curve,
Therefore, when carrying out the acquisition of sample data, it usually needs be divided into enabling process and shutdown process both of these case carries out
The acquisition of corresponding sample data.Certainly, the door closing speed curve of shield door and enabling rate curve can also be according to reality
It is set.
When shield door is in enabling process, what starting position at this time referred to is the position that shield door completely closes, and is stopped
Stop bit sets the position for referring to that shield door fully opens, namely the enabling process of shield door is finished at this time.Correspondingly, when screen
When covering door and being in shutdown process, what starting position at this time referred to is the position that shield door fully opens, and stop position refers to
The position that shield door completely closes, namely the shutdown process of shield door is finished at this time.
Shield door is from starting position normal movement to stop position namely shield door according to scheduled rate curve from starting
Position is moved to stop position, for example, shield door is moved to completely according to scheduled door closing speed curve from full open position
Closed position.In this course, the corresponding current value of driving motor when acquisition shield door is moved to each predeterminated position, and
As one group of sample data.When carrying out the acquisition of current value, the current sampling circuit being arranged in driving motor can be used
It is acquired, being specifically located in many circuit structures for current sampling circuit has application, and can also be according to practical feelings

The midpoint of starting position and stop position is such as chosen as a predeterminated position.Also, the quantity of predeterminated position be arranged and
Distribution can be set and be adjusted according to the actual situation.For example, can uniformly be chosen in the moving range of shield door more
It a position, can also be in the faster position of variation of shield door movement velocity, the faster position of movement velocity as predeterminated position
The setting of the more intensive predeterminated position of equal progress, so that the conventional current curve determined in subsequent step is more accurate.
S102: data fitting is carried out after acquisition multiple groups sample data, determines the conventional current curve of driving motor.
It can be and right after acquiring multiple groups sample data, using each group sample data of acquisition as sample data set
The sample data set carries out data fitting, determines the conventional current curve of driving motor.The conventional current curve characterizes
In the case where normal movement, during shield door is moved to stop position from starting position, corresponding to locating for shield door
The normal current value of the driving motor of each position.
Data fitting can use a variety of fit approach, and inventor considers to carry out data fitting using least square method
When, the relatively simple and fitting effect of calculating is preferable, therefore, in a kind of specific embodiment of the invention, is acquiring multiple groups

The conventional current curve of driving motor out.
In practical applications, the data volume for including in how many groups of sample datas and every group of sample data is specifically acquired
It can be set and be adjusted according to the actual situation.It is easy to understand, is carried out by taking the fit approach based on least square method as an example
Illustrate, such as in one embodiment, acquire 10 groups of sample datas, predeterminated position is set as 30, i.e. every group of sample number
30 current values for corresponding to each predeterminated position are contained in.In this embodiment, position is preset for any one
It sets, which has 10 current values acquired out, can find out the average value of this 10 current values, and can be successively right
This 30 predeterminated positions take the operation, carry out data fitting using least square method later, can determine driving motor
Conventional current curve.
S103: the electric current alarm threshold value curve of driving motor is determined according to conventional current curve.
In view of the convenience of calculating, a kind of common mode is by the electricity in preset first numerical value and conventional current curve
Flow valuve superposition, the curve after being superimposed are determined as the electric current alarm threshold value curve of driving motor.Also i.e. by conventional current curve edge
Y-axis positive direction translation, the distance of translation is preset first numerical value.
S104: during shield door is run according to the direction from starting position to stop position, driving motor is detected
Current value and shield door locating for target position, when the current value detected be higher than electric current alarm threshold value curve in correspond to
When the data value of target position, shield door stop motion is controlled.
It should be pointed out that above-mentioned step S101 to step S103 is to obtain electric current alarm threshold value song by sample data
The process of line is not to be intended to execute step S101 to step S103 each time in the control to the day-to-day operation of shield door
Operation, it can tested in advance, acquire experimentation in shield door operate normally when sample data simultaneously obtain electric current
Alarm threshold value curve can pass through the corresponding control system electric current report in the day-to-day operation of subsequent shield door
Alert threshold curve.And it be emphasized that the electric current report obtained when the data for the enabling process that sampled data is shield door
Alert threshold curve namely applies the curve in the enabling process of shield door, correspondingly, when the pass that sampled data is shield door
When the data of door process, the electric current alarm threshold value curve obtained namely applies the curve in the shutdown process of shield door.
When shield door is run according to the direction from starting position to stop position, the current value and screen of driving motor are detected
Cover target position locating for door, target position can be shield door from locating any during starting position to stop position
The present position of one position, shield door can be determined by the pulse that motor encoder exports, specifically, can pass through umber of pulse
Amount increases or decreases to characterize the variation of shield door position, and then can determine target position locating for shield door.
When the current value detected is higher than the data value for corresponding to target position in electric current alarm threshold value curve, say at this time
The case where running resistance of bright shield door increases, and shield door has been likely to occur folder people or folder object, needs to control shield door at this time
Stop motion prevents shield door from continuing movement and damages to people or object.
Using technical solution provided by the embodiment of the present invention, comprising: in shield door from starting position normal movement to stopping
During stop bit is set, the corresponding current value of driving motor when acquisition shield door is moved to each predeterminated position, and as one

Direction operation during, target position locating for the current value and shield door of driving motor is detected, when the electricity detected
When flow valuve is higher than the data value for corresponding to target position in electric current alarm threshold value curve, shield door stop motion is controlled.
Applicant, since the resistance of motion increases, can make it is considered that when the case where pressing from both sides people or folder object occurs in shield door
The electric current of driving motor increases, therefore when shield door moves to a certain position, detects that the electric current of driving motor at this time is higher than pair
Should be when the normal current of the position, shield door is likely to occur the case where pressing from both sides people or folder object.Therefore, in the scheme of the application,
When sample data is shield door normal movement, it is moved to the current value of the corresponding driving motor in each position, in acquisition multiple groups
Sample data and after carrying out data fitting, can determine the conventional current curve of driving motor.According to conventional current song
After line determines electric current alarm threshold value curve, when shield door is run according to from the direction of starting position to stop position to target
When position, if the current value of the moment driving motor detected, which has exceeded, corresponds to the position in electric current alarm threshold value curve
Data value, then can determine that the electric current of driving motor is excessive, and stop the movement of shield door.The scheme detection of the application

The electric current alarm threshold value curve of driving motor.
When moving to each position in view of shield door, the size of current of driving motor is different, i.e. conventional current curve is
The curve of one variation, and when electric current is larger, compared to the lesser region of electric current, normal fluctuation range can be bigger.
Therefore, preset second value can be multiplied with the current value in conventional current curve, the curve obtained after being multiplied determines
For the electric current alarm threshold value curve of driving motor.Using this kind of embodiment, when a certain position in conventional current curve is corresponding
Current value it is larger when, the numerical value in corresponding electric current alarm threshold value curve is just larger, so that in practical application, when what is detected
