Here, the normal operation mode NOR is an operation mode in which the car 6 can be driven at high speed according to call registration. The inspection operation mode INS is an operation mode in which the car 6 travels at an inspection speed under the manual operation of maintenance personnel. The buzzer 13 is sounded, for example, when the car 6 switches from the inspection operation mode to the normal operation mode.

  Further, the car 6 and the elevator control panel 3 are connected by a tail cord 14 for supplying power from the elevator control panel 3 to the car 6 and exchanging necessary information with each other.

  The elevator control panel 3 includes a wireless transmission / reception unit 31 that receives data necessary for start of inspection wirelessly transmitted from the car remote operation terminal 16 possessed by the maintenance staff 15, and the content received by the wireless transmission / reception unit 31. It is comprised by the operation control process part 32 which performs a required process, and the memory | storage part 33 with which it attaches internally or detachably.

  The storage unit 33 stores at least a normal operation control program related to the normal operation mode and an inspection operation control program related to the inspection operation mode, and further includes a maintenance management table 33a (see FIG. 2). The maintenance management table 33a includes data for authenticating as a genuine maintenance person {maintenance person identification data, terminal identification data (for example, equipment number) possessed by the maintenance person, and other data to be authenticated (for example, maintenance person name, maintenance area) Data, etc.)} is stored.

  The operation control processing unit 32 controls the operation of the car 6 according to the normal operation mode based on the normal operation control program, and also authenticates maintenance personnel based on the authentication data transmitted from the car remote operation terminal 16. Upon receipt of the inspection operation mode selection data transmitted from the car remote operation terminal 16 and the means for performing acceptance registration, etc., the mode is switched to the inspection operation mode, and the maintenance personnel get on the floor (standby floor). Means for moving and stopping the car 6, and when the car 6 is stopped on the floor, the maintenance staff stops at a position that is easy to get on the top of the car and opens the elevator door. And means for setting the safety switch and the inspection switch so that the inspection operation can be started.

  As shown in FIG. 3, the car remote operation terminal 16 is provided with a data input key section 16a and a liquid crystal display section 16b. In the data input key portion 16a, in addition to the data key 16aa for inputting data such as numbers and characters, an operation mode selection key 16ab for selectively inputting the inspection operation mode INS and the normal operation mode NOR, the selected operation mode is turned on.

  On the liquid crystal display unit 16b, for example, the operation contents and procedures of the maintenance staff 15 are displayed. For example, when the operation state of the normal operation mode NOR, the boarding floor (3F) waiting for inspection is instructed by the data key 16aa, predetermined information 3FFF including the boarding floor, authentication data A0126 representing the maintenance personnel 15, etc. Is displayed.

  Next, an operation of the car operation system configured as described above by remote operation and an operation procedure of the car operation method will be described with reference to FIG.

  First, the maintenance staff 15 possesses a car remote operation terminal 16 and goes to an appropriate boarding floor or machine room 2 as an elevator installation location of a building where inspection work is to be performed, and starts operation of the car remote operation terminal 16. Let

  The maintenance staff 15 operates the data input key part 16a of the car remote operation terminal 16 to input and transmit authentication data (for example, maintenance staff identification data A0126) indicating that the car is a genuine maintenance staff 15 (S1). .

  At this time, the elevator control panel 3 performs normal operation control under the normal operation mode NOR (S11). Here, when the wireless transmission / reception unit 31 of the elevator control panel 3 receives the authentication data transmitted from the car remote operation terminal 16, it passes it to the operation control processing unit 32.

  The operation control processing unit 32 temporarily stores the received authentication data in the storage unit 33, and then refers to the maintenance management table 33 a, and determines that the data is a genuine maintenance person 15 if there is matching authentication data. Then, authentic maintenance personnel identification data A0126 is registered together with the reception date / time in the reception registration area required in the storage unit 33 (S12). In this case, the operation control processing unit 32 may notify the car remote operation terminal 16 of the completion of reception if it is a genuine maintenance person 15.

  The maintenance personnel 15 sends an operation instruction to the inspection operation mode INS on the operation mode selection key 16ab of the car remote operation terminal 16 at least on the car boarding floor 17 where the inspection work is performed at least first after transmitting the authentication data, and then turns on. -The off key 16ac is set to ON and an instruction for selecting the inspection operation mode INS is input (S2).

  Subsequently, when the maintenance staff 15 inputs inspection required data including floor information indicating that the current car boarding floor 17 is, for example, the third floor, the operation state: INS is displayed on the liquid crystal display unit 16b of the car remote operation terminal 16. , Pulse value: 3FFF, Maintenance personnel: A0126 are displayed (S3). After confirming the display contents, the maintenance staff 15 transmits the data to the elevator control panel 3 as data necessary for starting the inspection (S4).

  The operation control processing unit 32 receives data necessary for the start of inspection via the wireless transmission / reception unit 31, confirms that it is a genuine maintenance person registered in the reception registration area, and then additionally checks the reception registration area. After registering the data necessary for the start, the mode is automatically switched to the inspection operation mode INS based on the selection instruction data of the inspection operation mode INS (S13).

  Further, the operation control processing unit 32 determines the pulse arrival value from the current position of the car 6 to the inspection start position of the car boarding floor 17 based on the pulse value of the car boarding floor 17: 3FFF (for example, the third floor): 3618. Is transmitted to the car remote operation terminal 16 via the wireless transmission / reception unit 31 (S14).

  As shown in FIG. 5, the car remote operation terminal 16 displays the received pulse arrival value: 3618 together with the inspection operation mode INS and inspection personnel identification data (S5).

  The operation control processing unit 32 transmits the pulse arrival value related to the inspection start position of the car boarding floor 17, and then transfers the car 6 to the car boarding floor (based on the pulse value 3FFF registered in the acceptance registration area of the storage unit 33. The position of the car 6 is lowered to 17). At this time, the pulse is counted up according to the moving distance, and the pulse count value is transmitted to the car remote operation terminal 16 (S15).

  As a result, the car entry pulse is updated in the liquid crystal display unit 16b of the car remote operation terminal 16 as shown in FIG. When the car entry pulse reaches the pulse arrival value (S6), for example, the operation control processing unit 32 sounds the buzzer 13 above the car 6, or the car remote operation terminal 16 sounds the built-in buzzer. Here, the maintenance staff operates the OFF button and transmits an OFF operation signal to the elevator control panel 3 (S6).

  After the operation control processing unit 32 receives the OFF operation signal and stops the car 6, or after the car arrival pulse and the pulse arrival value coincide with each other and the buzzer 13 is sounded, the car 6 is stopped. Then, the elevator door is opened (S16).

  At this time, the car safety switch 11 and the car inspection switch 12 at the upper part of the car 6 are lowered to the landing position where the maintenance personnel 15 on the car boarding floor 17 can reach.

  Accordingly, the maintenance person 15 cuts the car safety switch 11 to make the car 6 movable and turns on the car inspection switch 12 to run at the inspection speed under the manual operation of the maintenance person 17. After setting as described above (S17, S18), board the upper portion of the car 6.

  The maintenance staff 15 rides on the upper part of the car 6 and then checks the equipment, operates the UP button or the DN button of the car remote operation terminal 16, and transmits it to the operation control processing unit 32 of the elevator control panel 3. Meanwhile, the car 6 is moved up and down at the inspection speed, and the various equipment and components in the hoistway 1 are inspected.

  When performing the inspection work, the work procedure mounted on the car remote operation terminal 16 and the items of each work procedure are displayed on the liquid crystal display unit 16b, and a check is made after the work item is finished to check the inspection work state. Remember.

  Therefore, according to the embodiment as described above, it is necessary to start the inspection by operating the car remote operation terminal 16 on the car boarding floor 17 after registering as a genuine maintenance person in the elevator control panel 3. Since the car 6 is transmitted and the car 6 is switched to the inspection operation mode, the car 6 can be promptly moved to the car boarding floor 17 of the maintenance staff and stopped.

  Further, when the car 6 stops at the car boarding floor 17, the car safety switch 11 and the car inspection switch 12 above the car 6 are within the reach of the maintenance personnel 15, so these switches 11, 12 The necessary preparations for starting the inspection can be set by operating.

  In addition, since the elevator can be moved up and down freely at the inspection speed under the operation of the car remote operation terminal 16, the inspection work can be carried out smoothly and greatly contributes to shortening the inspection time. To do.

  Further, by enabling the work procedure to be displayed on the liquid crystal display unit 16b of the car remote operation terminal 16, it is possible to prevent omission of inspection and to check and store the inspection work state after completion of the work item.
