[Prior Art] Conventionally, when the earthquake is detected, when the earthquake is sensed, the stop is stopped on the nearest floor, and after the threshold is opened, the threshold is closed and the operation is stopped. After that, the inspection by the specialist of the elevator is resumed and the operation is resumed. Inspections by specialists are confirmation of the machine in the elevator or the equipment in the hoistway, or confirmation that the passenger is not left in the elevator, or that the elevator is traveling at a low speed. In addition, for the purpose of the early-stage repair from the stop state, there is an elevator that does not depend on the inspection by the technician of the elevator, and automatically performs the diagnosis operation, and the elevator is repaired by the stop operation (see, for example, Patent Document 1). [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. The technicians caused by the inspection before coming to walk. When the above-described automatic diagnosis operation is performed, the inspection by the expert of the elevator is not carried out, and the state of the tower of the elevator is not known, so that there is a possibility that the weight is in contact with the elevator. -5- (2) 1314132 The object of the present invention is to provide an inspection by a specialist who does not rely on an elevator. When the diagnostic operation is automatically performed, the balance weight and the lift box are prevented from contacting each other, and the lift box and the weight are damaged. Lift control unit. According to the elevator control device of the present invention, the means for stopping the operation of the elevator when the swing amount of the predetermined swing or more is sensed, and the means for automatically performing the diagnosis operation when the operation is stopped, and the means for stopping the repair are further provided: The position detecting means for the position of the lift car and the counterweight, and the speed control means for outputting the deceleration command when the distance between the position of the lift car and the counterweight is less than or equal to a predetermined value. In addition, when the elevator car or the counterweight is located on the floor of the ±1 floor from the floor where the two intersect, the output deceleration command may be used. According to the present invention, in the automatic diagnosis operation during an earthquake, if the lift car is close to the counterweight, the lift car and the counterweight are decelerated, so that the damage when the lift car and the counterweight are approached can be suppressed. [Embodiment] FIG. 1 is a block diagram showing an embodiment of the present invention. In Fig. 1, 1 is an elevator control device, 2 is a seismic sensor that transmits a situation in which a predetermined swing or more is transmitted to the elevator control device 1, 3 is a lobby button for calling the elevator car, and 4 is a detection lift. The load sensor of the load in the compartment, 5 is the elevator car that the passenger boarded, 6 is the floor detection device that detects the position of each floor, 7 is the top surface illumination in the elevator car '8 is the counterweight, 9 is the winch' 1〇 It is an encoder that detects the pulley speed or the number of revolutions mounted on the hoisting machine 9, and 20 is a cable that is wound around the pulley -6-(3) 1314132 of the hoisting machine 9 to drive the lift box 5 and the counterweight 8. Fig. 2 is a control flow chart showing the case where the elevator control device 1 according to Fig. 1 is not in an earthquake. When the seismic sensor performs the action (S 2 1 ), the traveling elevator stops at the nearest floor (S22) 'extinguishes the lighting in the elevator car (S23), and after closing the threshold, the door sill is closed (S24), It becomes a controlled operation when the earthquake is completed (S 2 5). In the case of the control operation during the completion of the earthquake, the ® elevator control unit performs the diagnostic operation (S 26). If there is no abnormality, the operation is stopped by the stop operation (S27). Fig. 3 is a flow chart showing the diagnosis operation. Check if there are passengers in the elevator car (S3 1), and if there are no passengers, perform the low speed diagnosis operation (S32). If there is no abnormality in the low speed diagnosis operation, the floor stop diagnosis operation is performed (S33). If the travel is stopped on each floor, the diagnostic operation is not abnormal, and the high-speed travel diagnosis operation is performed (S3 4). If there is no abnormality in the high-speed travel diagnosis operation, perform the threshold opening and closing diagnosis operation (S35). If there is no abnormality in the threshold opening and closing diagnosis operation, the repair will be performed by stopping the operation. In the present embodiment, at the time of the low speed diagnosis operation (S3 2), the counterweight 8 is decelerated to a target speed of less than or equal to the predetermined speed before crossing the lift box 5, and the lift box damage when the counterweight 8 comes into contact with the lift box 5 is suppressed. In addition, in the same manner, after the completion of the low-speed diagnosis operation (S3 2), the floor stop diagnosis (S33) and the high-speed travel diagnosis (S3 4) are similarly decelerated to a predetermined low speed before the counterweight 8 intersects with the lift box 5, It is possible to suppress the damage of the elevator car when the counterweight 8 comes into contact with the elevator car 5. (4) 1314132 Fig. 4 is a view showing the detailed configuration of the elevator control device 1. In Fig. 4, reference numeral 14 denotes a position detecting device for detecting the positions of the lift box 5 and the weight 8. The position detecting device 14 detects the position of the elevator car 5 from the number of revolutions or the speed (B) of the pulley detected by the encoder 10. Further, the position detecting device 14 is an intersection of the lift car 5 and the counterweight 8 in the hoistway, and the position of the lift car 5 is symmetrical with the position of the counterweight 8, and the distance from the intersection is approximately equal. The detected liters | The position of the descending compartment 5 is calculated by calculating the position of the counterweight 8 (refer to Fig. 5). Further, the position of the weight 8 may be detected after the position of the detected lift box 5 and the length of the cable 20 are calculated. Further, the position detecting device 14 calculates the distance between the elevator car 5 and the counterweight 8 from the detected position of the elevator car 5 and the counterweight 8, and outputs the distance. Further, reference numeral 11 denotes a position correcting means for calculating a phase difference component between the position data (D) of the lift car 5 from the floor detecting device 6 and the position (E) of the lift car 5 detected by the position detecting device 14, by the phase difference component (F), the distance between the lift box 5 and the counterweight 8 output from the position detecting device φ 14 is corrected. 12 is a memory device that accommodates the distance (G) between the corrected weight 8 and the lift box 5. 13 is a speed control device that reads the distance (H) of the weight 8 accommodated in the memory device 12 from the lift box 5, and outputs a deceleration command when the counterweight 8 and the lift box 5 are below a predetermined distance. ). Further, the speed control device 13 controls the hoisting machine 9 by the deceleration command (A) by the speed (B) of the pulley detected by the encoder 1 接近 being close to the predetermined low speed. Fig. 5 is a view showing an example of means for detecting the position of the weight of the position detecting device 14 of Fig. 4. The position detecting device 14 uses the intersection of the lift box 5 and the -8-(5) 1314132 counterweight 8 as the origin (〇), and the position of the lift box for the origin (〇) is detected as Α. The position of the lift car 5 and the counterweight 8 is symmetrical with respect to the intersection and the distance is equal, whereby the position of the counterweight is detected as -A. Fig. 6 is a view showing an example of the speed control means of the speed control device 13 of Fig. 4. The speed control device 13 is such that when the distance between the lift box 5 and the counterweight 8 decreases with time, that is, when the lift box 5 and the counterweight 8 travel in the intersecting direction, the distance 2x between the lift box 5 and the counterweight 8 is judged. When it is set to > 値 2 X or less, the deceleration command is output. Thereafter, the speed of the pulley is close to the predetermined low speed, and the hoisting machine 9 is controlled by the deceleration command. Here, the predetermined low speed is such that the speed of the lift box 5 and the counterweight 8 is set to be substantially no damage even if the two are in contact with each other, or a number of speeds V which are slight damages without damage to the repair. The predetermined 値 2X of the distance is a speed at which the speed of the lift box 5 and the counterweight 8 is a predetermined speed V at the time of intersection, and after the weight 8 and the lift box 5 pass the intersection point, the speed control device 13 cancels the deceleration command. And the output acceleration command. Further, instead of using the distance 2x between the φ lift box 5 and the counterweight 8, the distance X between the intersection and the lift box 5 is used, and it is understood that the control can be performed in the same manner even when compared with the predetermined 値X. Fig. 7 is a view showing an example of a speed pattern of the lift box 5 and the weight 8 of the present embodiment. Further, it is also described that the elevator car 5 is close to the counterweight 8 in the hoistway. Before the counterweight 8 intersects with the elevator car 5, the speed control device 13 outputs a deceleration command. When the counterweight 8 and the elevator car 5 travel in the direction of departure, the speed control device 13 outputs an acceleration command. It is not limited to the above-described embodiment, and various modifications can be made within the scope of the technical idea of the present invention in the range of -9-(6) 1314132. For example, it is also possible to output a deceleration command depending on the floor on which the elevator car 5 and the counterweight 8 are located. At this time, the position detecting device 1 4' of Fig. 4 is a floor that outputs the position of the elevator car 5 detected by the floor detecting device 6, and detects the position of the elevator car or the counterweight of the floor where the elevator car intersects the counterweight. floor number. The speed control device 13 outputs a deceleration command when it is determined that the number of floors of the intersecting floor detected by the position detecting device 14 is 1 floor.
