DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a circuit configuration of a door opening / closing abnormality inspection apparatus 10 according to the present embodiment. Note that the door opening / closing abnormality inspection apparatus 10 described in the present embodiment also has a function as a door opening / closing control device that controls the opening / closing operation of the door in a normal use state.

The door opening / closing abnormality inspection apparatus 10 includes a CPU (Central Processing Unit) that performs a central function of door opening / closing control. The CPU 20 has a ROM (Read Only Memory) 31 and a RAM (Random Access Memory).
Memory) 32 is connected. In the ROM 31, fixed data such as a program indicating a control procedure and initial values of various operations are stored in advance.

The RAM 32 is a work memory for temporarily storing various information when the CPU 20 executes the program. For example, at the time of inspection, a door opening / closing stroke, a door moving speed during opening / closing, etc. Is used as an area for storing.

The CPU 20 is connected to a detection switch 33 for detecting the passage of a person who triggers the opening of the door, and a motor control circuit 35 for controlling the rotation of a motor 34 which is a driving source for opening and closing the door. . The detection switch 33 is
It is an infrared sensor for detecting the approach of a pedestrian, and is arranged near an entrance where a door is installed.

In both the normal operation and the inspection, the door opening / closing abnormality inspection apparatus 10 opens the door in the closed state to the fully open position when the detection switch 33 detects the approach of a person, and thereafter, for a certain period of time. When the time has elapsed, the movement of the door is controlled so as to close the door. Here, the door to be inspected is a hanging slide door, and a guide rail for guiding the lower end of the door and regulating the position is arranged on the floor surface side.

The motor 34 is provided with a Hall sensor 36 for detecting its rotation angle. The Hall sensor 36 outputs a pulse signal every time the rotating shaft of the motor 34 rotates by a predetermined angle, and functions as a speed detecting means. The CPU 20 is connected to a rotation speed detection circuit 37 that counts a pulse signal output from the Hall sensor 36.

The F / V conversion circuit 38 is a circuit for converting the period of the pulse signal output from the Hall sensor 36 into a voltage, and the A / D conversion circuit 39 quantizes the output voltage of the F / V conversion circuit 38. This is a circuit for converting to an 8-bit digital signal. Therefore, the output value of the A / D conversion circuit 39 indicates a value corresponding to the number of pulse signals per unit time, that is, a value corresponding to the moving speed of the door.

The CPU 20 recognizes the moving distance (stroke) of the door based on the number of pulse signals counted by the rotation speed detecting circuit 37. In addition,
The CPU 20 is connected to a full-open detection switch (not shown) that is turned on when the door is fully opened.
U20 determines that the door has reached the fully open position by turning on the switch.

The timer 41 performs a function such as counting the open holding time from when the door is fully opened to when the door is shifted to the closing operation. The error notification means 42
It reports the occurrence of various abnormal conditions in addition to the inspection result, and has a display unit for displaying error symbols and the like. In addition, the error notification unit 42 can output an abnormal signal to a centralized management device or the like.

The CPU 20 has, in addition to the function of controlling the opening and closing operation of the door in the normal state, a function as a judging means 21 for judging whether or not the load caused by the opening and closing of the door is within a normal range.

Next, the operation will be described. FIG. 2 shows a flow of inspection performed by the door opening / closing abnormality inspection apparatus 10 at the time of installation or the like. First, after turning on the power of the door opening / closing abnormality inspection apparatus 10 (step S101), it is confirmed that the door is at the fully closed position (step S102). Thereafter, the motor 34 is driven to open the door, and the CPU 20 reads the travel distance (open stroke) in the opening direction based on the output value of the rotation speed detection circuit 37 (step S103). Next, the motor 34 is driven to close the door, and the travel distance (closing stroke) at that time is read (step S104).

The CPU 20 constantly monitors the moving speed of the door while the door is being opened and closed, and stores the value in the RAM 32. That is, the output value of the A / D conversion circuit 39 is stored, for example, every one second.

After completing the opening and closing of the door, the CPU 20
It is determined whether or not the opening stroke and the closing stroke match (step S105). If they do not match (step S105; N), a stroke abnormality is displayed on the error display means 42 (step S108). Then, the operation of opening and closing the door is stopped (step S110). The stroke abnormality is, for example, a case where an obstacle or the like is erroneously placed on the path of the door during the opening and closing operation of the door. Therefore, after the obstacle is removed, the inspection is performed again.

When the opening stroke and the closing stroke match (step S105; Y), the value stored in the RAM 32, that is, the number of pulse signals per unit time is read out, and this is determined by a predetermined reference. It is determined whether the value is equal to or less than the value (step S106). If the number of pulses per unit time is equal to or higher than the reference value, that is, if the moving speed of the door is equal to or higher than a certain reference speed (Step S106; Y), it is determined that the load accompanying opening and closing of the door is within the normal range. The determination is made, and a normal operation possible display is performed on the error notification means 42 (step S107).

If the number of pulse signals per unit time is equal to or less than the reference value (step S106; N), it is determined that the load caused by opening and closing the door is excessive, and the error notification means 42 is provided.
Is displayed (step S109). In this case, once the power supply of the door opening / closing abnormality inspection device 10 is turned on,
Cutting (step S110), door weight and rail,
An inspection of a mechanism such as a runner is performed (step S112). Then, after repairing the cause of the abnormality or confirming that there is no abnormality, the power of the door opening / closing abnormality inspection apparatus 10 is turned on again to perform the inspection.

As described above, since it is checked whether the load caused by opening and closing the door is normal based on the moving speed of the door, it is easy to check whether the weight of the door is excessive or whether the mechanisms such as rails and runners are normal. Can be done. In addition, since the above-described inspection can be performed together with the operation of confirming that the opening stroke and the closing stroke match, the inspection can be completed in a short time without increasing the number of inspection steps.

When the stroke is 30 cm or less, even if the opening stroke and the closing stroke match, it is handled as if there is an abnormality in opening and closing the door. Further, the speed immediately after the start of the movement of the door is not determined. Immediately before stopping the movement of the door, the brake is controlled so as to reduce the moving speed of the door, so that the period is also excluded from the determination target.

In the embodiment described above, the inspection of the load abnormality is performed in addition to the inspection of the opening / closing stroke. However, these inspections may be performed independently. Further, in the embodiment, the moving speed immediately after the door movement is started or immediately before the stop is excluded from the load determination target. If it is changed according to the speed, it is possible to determine whether or not there is a load abnormality during the entire stroke.

[0031]

According to the door opening / closing abnormality inspection apparatus and the inspection method according to the present invention, whether or not the load accompanying the opening / closing of the door is normal based on the moving speed of the door is inspected. It is possible to easily inspect whether the mechanisms such as the rail and the runner are normal.
