Abstract

PROBLEM TO BE SOLVED: To quickly and easily perform diagnosing and adjusting work of door opening/closing regardless of experience and knowledge by comparing respective floor door opening-closing speeds found by processing signals from noncontact type optical sensors to move a door with ideal opening/closing speed data, and displaying a door diagnosing result and an adjusting method of the respective floors. SOLUTION: Noncontact type optical sensors (12a and b) output color information of a reflector 11 which is classified by color into two colors and is stuck to a door, by pulse signals Sa and Sb. A data gathering part 13 measures the pulse signals Sa and Sb, and temporarily stores them over the whole process of the door, and measures the whole floors. The door moving direction is detected by transferring the signals Sa' and Sb to an opening/closing direction detecting part 14 as a measured result with respective floors, and an operation is performed on respective floor door speeds Va by an opening/closing speed operation part 15, and they are respectively compared with ideal opening/closing speed data Vb. Respective floor door opening/closing characteristics are diagnosed from a compared result, and an adjusting method is displayed. Therefore, respective floor doors can be easily adjusted in a short time even if experience is little.

On the third floor, the gap δ13 is larger than the normal value because the building side door 4 is shifted to the right with respect to the car side door 3 and the gap δ
23 is small. On the fourth floor, since the building-side door 4 is further shifted leftward than on the second floor, the gap δ14 is smaller than the gap δ12 on the second floor, and the gap δ24 is 2
It is assumed that it is even larger than the floor gap δ22.

When measuring the opening / closing characteristics of each floor door having such a positional relationship, the worker follows the step 1 of the flowchart and attaches the reflector 1 to the car side door 3 as shown in FIG.
1 and the non-contact type optical sensor 12 is set.
Subsequently, the door diagnostic apparatus 1 is started according to step 2, and a door opening / closing operation is performed as step 3. Thus, the non-contact optical sensors 12a and 12b output Hi and Lo pulse-like signal voltages Sa and Sb. The data collection unit 13 starts measuring the pulse signals Sa and Sb with the generation of the pulse signal as a trigger. As shown in step 5, the data collection unit 13 outputs the pulse signal S over the entire stroke of the door.
a and Sb are temporarily stored, and the measurement of the first floor door is completed. The operator performs this operation until the measurement of the pulse signals Sa and Sb of the fourth floor door shown in step 8 is completed.

After the measurement of the pulse signals Sa and Sb of the non-contact optical sensors 12a and 12b is completed on all floors, the data collecting unit 13 sends the signal Sa 'to the opening / closing direction detecting unit 14 as shown in step 9. And Sb 'are transferred as measurement results for each floor. In step 10, the opening / closing direction detecting section 14 detects the moving direction of the door from the order in which the signals Sa 'and Sb' are generated as described with reference to FIG. Fifteen
Then, the opening / closing speed Va of each floor door is calculated using the above equation (1). The opening / closing speed Va of each floor door obtained as described above is stored in the opening / closing speed storage section 16 in accordance with step S12.

Next, at step 13, the door diagnostic apparatus 1 reads out the ideal opening / closing speed data Vb from the ideal opening / closing speed data storage section 17. Next, as shown in step 14, the opening / closing speed V of each floor door calculated by the comparing unit 17 is calculated.
a and the ideal opening / closing speed data Vb, respectively, to clarify the difference between the two features and the speed difference at the same door position for each floor. The comparing unit 17 clarifies, for each floor door, two points, that is, the time from when the door is activated to when the speed drops due to engagement, and whether or not there is a door collision at the closed end and the open end.

FIG. 9 shows the opening / closing speed of each floor door measured this time, and the contents of diagnosis by the diagnosis unit 19 in step 5 will be described. After the door opening speed on the first floor operates at a low speed, the speed is reduced due to the engagement between the building-side engaging device 44 and the car-side engaging device 38 shown by B in the figure. Thereafter, the vehicle accelerates up to the rated speed, and after steady running, the opening deceleration start contact 39b operates at OSD1 in the figure to start deceleration, thereby ending the door opening operation. Also, when the door is closed, after acceleration and steady running, the closing deceleration start contact 39a operates at CSD1 in the figure to start deceleration, and the door closing operation is completed after low speed running.

Since the gap δ22 is larger than the normal state, the door opening speed on the second floor is later than the ideal opening / closing speed data Vb indicated by the dotted line in the timing chart of the engagement operation, and the speed drop due to the engagement occurs later. ing. When the door is closed, the speed rise immediately after the start of the closing operation is gentler than normal and the building-side door 4 is disengaged earlier than the ideal opening / closing speed data Vb. Collides with each other, and a phenomenon occurs in which the speed is generated in a direction opposite to the normal direction.

Based on the above diagnostic results, the door diagnostic apparatus 1 determines a method of adjusting each floor door as follows. The first floor is unadjusted, the second floor moves the car-side engaging device 44 in the direction in which the gap δ22 decreases, and the third floor moves the building-side engaging device 44 to the building in the direction in which the gap δ13 decreases. .

As a result of the diagnosis, the opening / closing characteristics of the second-floor door are such that the reduced timing of the speed becomes normal as shown by the solid line in FIG. The opening and closing characteristics have been improved. On the third floor, the gap δ13 is reduced so that the engagement timing becomes normal, and the rise of the speed when the door is opened and the fall of the speed when the door is closed are represented by solid lines, and coincide with the ideal opening / closing speed data Vb. The opening and closing characteristics have been improved. However, the opening and closing characteristics of the fourth-floor door are such that, due to the reduced gap δ24, the timing of the drop in speed when the door is opened approaches the ideal opening and closing speed data Vb, but the door-opening phenomenon still occurs at the door open end. .

Therefore, the door diagnostic apparatus 1 determines in step 16 that it is necessary to adjust the fourth-floor door in which the door stop phenomenon has occurred, and in step 162 displays the diagnostic result on the display unit 110. Then, the worker is asked for an answer as to whether the mounting position of the building-side engaging device 44 can be adjusted. If the answer is “OK”, the door diagnostic apparatus 1 reduces the gap δ24 as shown in step 172, and displays this to the display unit 110 in step 18.

Thereafter, in step 15, the door diagnostic apparatus 1 diagnoses the re-measured door opening / closing characteristics shown in FIG. 12 as follows. Regarding the opening and closing speeds of the first to third floors, since the deceleration start time has been increased from CDS1 to CDS2, the traveling time at low speed is longer than the ideal opening and closing speed, but there is no practical problem, and there is no practical problem. Since the deceleration start time of the door is earlier, the door speed at the time of the disengagement of the building side door 4 is reduced as compared with the conventional case, and it is diagnosed that the door stop phenomenon has been eliminated.
