DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an illustrated embodiment.

In FIG. 1 to FIG. 5, reference numeral 1 denotes a hoistway provided vertically to a building.
A secondary conductor 2 of the linear motor is provided upright in the vertical direction, and a primary coil 4 of the linear motor is provided on the rear surface of the car 3 facing the secondary conductor 2 of the linear motor. It is provided so as to move up and down by the thrust action. In addition, above and below the hoistway 1, horizontal roads 5 and 6 are provided horizontally so as to communicate with the hoistway 1. Each secondary conductor (not shown) of the linear motor is provided horizontally with the same configuration as the road 1. Further, a primary coil (not shown) of the linear motor is provided on a lower surface of the car 3 facing the secondary conductor of the linear motor so as to run by a thrust action with the secondary conductor.

Therefore, the car 3 moves up and down in the hoistway 1 by the thrust action of the primary coil 4 and the secondary conductor 2 of the linear motor, and the car 3 moves in the traversing paths 5 and 6. Is driven horizontally by the thrust between the primary coil and the secondary conductor of the linear motor.

On the other hand, the hoistway 1 and the traversing paths 5 and 6 are provided at regular intervals so that each detection sensor 7 detects the position of each car 3. Also, FIG.
As shown in FIG.
(Central processing unit) 8 is connected to the CPU.
8 is connected to a memory device 9 which stores data in an intrusion risk area range for preventing another car from entering the area of each car 3. That is, the CPU 8 includes:
Each of the detection sensors 7 is connected via an input device 10, and a signal input to the input device 10 by detecting the position of the car 3 from each of the detection sensors 7 is a memory that stores data of an intrusion risk area. The data from the device 9 and the CP
At U8, the calculation is performed so as to prevent another car from entering the area of each car 3 described above.

On the other hand, the CPU 8 includes an inverter 12 provided with an inverter control device 11 for controlling deceleration and stop and a power supply section switching device 13 and an output device 14.
And the output signal from the CPU 8 is transmitted to each inverter 12 provided with each inverter control device 11.
And each car 3 by the power supply section switching device 13
Is controlled.

That is, the CPU 8 determines whether the next area of the detected car 3 is set from the dangerous area and the other cars 3 by the information of the memory device 9 assigned to each area. If it is determined that the area is not designated as a dangerous area, a new dangerous area is set by the movement of the car 3 and information of the memory device 9 assigned to this area is written, and the inverter control devices 11 In order to supply the speed command to the primary coil 4 in the section in which the output power from each inverter 12 is moving, a command to the power supply switching section device 13 is output through the output device 14. Further, when the destination area of the car 3 is set as a dangerous area by another car, a command to decelerate or stop is output to each inverter control device 11 to supply power to the dangerous area. Does not output commands. These control processes are performed for each car 3.

Hereinafter, the operation of the present invention will be described.

Accordingly, in FIGS. 2 to 4, at least two or more cars 3 traveling on the hoistway 1 and the traversing paths 5 and 6, the car 3 traveling on the hoistway 1 and the traversing paths 5 and 6. When the traveling position of each car 3 is detected by each of the detection sensors 7, the detection sensors 7
Are input to the input device 10, and the input device 10 transmits signals from the respective detection sensors 7 to the CPU. Then, the CPU calculates the signals from the detection sensors 7 and the data from the memory device 9. When the intrusion of another car is detected in the danger area of each car 3, the output signal from the CPU 8 causes the inverter 12 to pass through each inverter control device 11.
In addition, the power supply section switching device 13 is controlled, thereby preventing a collision with the other car 3 and preventing a collision with the other car 3 to improve safety. That is, as shown in the flowchart of FIG. 3 and FIG. 4, assuming that the car 3 is located in the area 2 and ascends to the area 5, the areas 1, 2, and 3 are regarded as dangerous areas, Command the car.

Next, when the car 3 moves to the area 3,
The dangerous area also moves to areas 2, 3, and 4.

That is, the condition for moving the car 3 is based on the condition that the destination area is not designated as a dangerous area by another car 3. As shown in FIG. 1, when a pair of upper and lower traversing paths 5 and 6 are connected to both hoistways 1 to raise or lower the car 3 or to run, one hoistway 1 is dedicated to ascent and the other. By setting the hoistway 1 to get down only, the car 3 can be circulated to improve the transport capacity.

On the other hand, when the car 3 reaches the connection between the hoistway 1 and the traversing roads 5 and 6, it is confirmed that the car 3 has not been designated in the dangerous area beyond the traversing roads 5 and 6. As shown in the timing chart of FIG. 5, in order to output a command to a traversing device (not shown) provided in the car 3 and to confirm these operations by a control device (not shown), While the car 3 is in the traversing mode, a signal during traversing is output from the control device. When the lateral movement of the car 3 is completed and the car 3 enters the elevating mode, the traversing device outputs a signal indicating the completion of the traversing of the car to the control device.

As described above, according to the present invention, until the output signal is detected by the above-mentioned control device, the area of the traversing destination is designated as the dangerous area, and the entry of another car 3 is prohibited. As a result, the car 3 can be safely moved laterally.

The lateral movement of the car 3 is performed based on the flowcharts shown in FIGS.

[0022]

As described above, according to the present invention, the detection sensors of the cars are provided at regular intervals on the hoistway and the traversing path, and each detection sensor is provided within the area of each car. Connected to a CPU provided with a memory device storing data of an intrusion risk area for preventing entry of another car, and an inverter provided with an inverter control device for controlling power supply of each car to the CPU, and a power supply section. Since a switching device is connected, an input signal from each of the detection sensors and data from the memory device are calculated by the CPU, and an output signal from the CPU controls the inverter and the power supply section switching device. It has excellent effects such as not only preventing collision of other cars, but also improving the transportation power, driving efficiency and safety.
