  In each group communication monitoring means 211 and each group communication monitoring means 311, for example, data for confirming the communication state is periodically transmitted from the elevator group management device 100 to each car control device, and each group communication means 210 and each group Whether each communication of the group is normal (can be received regularly) or abnormal (cannot be received regularly) is determined by whether or not the communication means 310 periodically receives confirmation data. To do.

  Further, in each car control device communication monitoring means 216 and each car control device communication monitoring means 316, for example, each car control device periodically transmits data for checking the communication state, and each car control device. Whether each group communication is in a normal state (can be received regularly) or abnormal state (periodic) depending on whether the inter-communication unit 213 and each car control unit communication unit 313 regularly receive the confirmation data. Is not received automatically). Here, the abnormal state of the second communication state refers to interruption of the communication network between the car control devices, failure of at least one of the car control devices, and the like.

  The landing destination floor registration devices 400-1 to 400-n are installed at or near the landing on each floor, and accept input from a user who wants to get on the elevator. The floor that the user uses for the destination destination floor registration device is registered as the landing floor (registering the landing floor), and the floor that the user entered as the destination of the car (the floor that the user wants to go to) is the destination floor. Registered (destination floor registration).

  The landing destination floor registration devices 400-1 to 400-n are connected to the elevator group management device 100. Moreover, it is connected to one group of car control devices (for example, one group consisting of the car control device 201-1 and the car control device 301-1) that controls each car in the same hoistway. In the following description, the hall destination floor registration device 400-1 will be described in particular.

<Operation>
<Operation in normal state>
First, the operation of the multi-car elevator control system according to the present embodiment when the communication state between the elevator group management device 100 and each car control device is normal will be described.

  The elevator group management device 100 receives the landing floor and the destination floor registered in the landing destination floor registration device 400-1 installed on each floor, and the call assignment means 101 determines the assigned car. Here, the “assigned car” is a car assigned to a registered landing floor and destination floor among a plurality of cars in the hoistway, and is it possible to reach the landing floor and the destination floor? It is determined in consideration of whether the arrival is efficient.

  The elevator group management apparatus 100 assigns allocation information to each car control device among the car control devices 201-1 and 301-1 corresponding to the determined allocation car through the group communication means 102. Send. Here, the “assignment information” is information indicating an assigned car and a landing floor and a destination floor to which the car should go.

  Each car control device that controls the assigned car is from the installation floor (the landing floor) of the registered landing destination floor registration device 400-1 to the registered destination floor in the car operation control means provided in each car control device. Is registered, and operation control of the corresponding car (that is, the assigned car) is performed. Here, the “destination destination call” is a command that requests that the assigned car be operated from the landing floor to the destination floor.

  At this time, the distance between other cars in the same hoistway is always managed by the elevator group management device 100, and when the distance falls below a predetermined distance, the operation of the car is stopped.

  The call assigning means 101 transmits the assigned car number to the landing destination floor registration device 400-1 in which the landing floor and the destination floor are registered, and the landing destination floor registration device 400-1 registers in the display unit in the device. The destination floor (for example, “5”) and the assigned car number (for example, “A”) are displayed.

<Operation in abnormal state>
Next, an operation when any one of the communication monitoring units in the group detects that the first communication state is an abnormal state will be described. Here, in particular, a case will be described in which each communication monitoring unit 211 detects that the first communication state is an abnormal state, but the other communication monitoring units in each group detect that the first communication state is an abnormal state. Even in this case, the same operation can be performed.

  When each group communication monitoring unit 211 detects an abnormal state of the first communication state, communication abnormality information is transmitted from each group communication abnormality information transmitting unit 212. The communication abnormality information is information indicating that the first communication state between each car control device 201-1 and the elevator group management device 100 is an abnormal state.

  Then, the communication abnormality information is transmitted to each car control device communication means 313 in each car control device 301-1 via each car control device communication means 213. In this way, in each car control device in the same hoistway, it is possible to grasp that any group communication monitoring means in the same hoistway has detected an abnormal state of the first communication state.

  When the communication abnormality information is shared by each car control device 201-1 and each car control device 301-1, each car control device 201-1 and each car control device 301-1 transmit information from the elevator group management device 100. The operation management of the car 200-1 and the car 300-1 can be carried out without using it. The operation management can be performed in the same hoistway operation management means 214 or the same hoistway operation management means 314. Below, the case where operation management is performed by the operation management means 214 in the same hoistway is demonstrated.

  The operation management means 214 in the same hoistway can manage the operation of all the cars in the target hoistway, that is, in response to the landing destination call by the operation management means 214 in the same hoistway, Set in advance so that the car will respond.

  In the same hoistway operation management means 214, the distance at which the upper and lower cars (the car 201-1 and the car 300-1) can operate safely without contacting each other, that is, the distance between the upper and lower cars is the respective stopping condition. The operation of the upper and lower cars is controlled so that the distance is not less than the predetermined distance derived from.

  Specifically, first, the same hoistway operation management means 214 causes the car 200-1 and the car 300-1 to respond to the registered landing destination calls respectively.

  Next, the operation management means 214 in the same hoistway selects the car 200-1 that is the upper car after the car 200-1 and the car 300-1 have appropriately completed all responses to the registered landing destination calls. Move to the top of the hoistway, that is, the top floor and stop. Note that the stop position is not limited to the top floor, and may include a stop position (such as a car position at the time when an abnormal state of the first communication state is detected) in the middle of the hoistway.

  Next, for further landing floor registration and destination floor registration from the landing destination floor registration device 400-1, the same hoistway operation management means 214 selects the car 300-1 as an assigned car, and the landing destination floor registration device 400-1 is displayed.

  Further, the same hoistway operation management means 214 instructs the car operation control means 215 to respond to the registered landing destination call. The car operation control means 215 that is instructed to respond controls the car 300-1 based on the landing destination call. The same hoistway operation management means 214 sends a response to the registered landing destination call to the car operation control means 315 which is a car operation control means in each other car control device in the same hoistway. You may instruct. In that case, the car operation control means 315 instructed to respond controls the car 300-1 based on the landing destination call.

  Further, the operation management means 214 in the same hoistway grasps the position of the car 300-1 via each car control device communication means 213, and even if the car 300-1 travels, the operation management means 214 communicates with the car 200-1 that is stopped. It is always checked whether the distance between them is less than the above-mentioned predetermined distance. When the distance from the stopped car 200-1 is equal to or less than the predetermined distance, the car operation control means 215 is instructed to immediately stop the operation of the car 300-1.

  In addition, when the first communication state is an abnormal state, in other hoistways, the operation can be continued for cars having different arrangements in the hoistway. That is, for example, in one hoistway, the uppermost car in the hoistway (upper car) is continuously operated, and in the other hoistway, the lowermost car (lower car) in the hoistway is operated. Can continue.

  The operation in the hoistway where the upper car is the car 200-2 and the lower car is the car 300-2 will be specifically described.

  When an abnormal state of the first communication state is detected, the operation management means 214 in the same hoistway appropriately responds to the landing destination calls registered in the upper and lower cars, and then raises and lowers the car 300-2 as the lower car Move to the bottom of the road, that is, the lowest floor and stop. The stop position is not limited to the lowest floor, and may be a case where a stop position (the position of the car at the time when the abnormal state of the first communication state is detected) is provided in the middle of the hoistway.

  Next, for further landing floor registration and destination floor registration from the landing destination floor registration apparatus 400-2, the same hoistway operation management means 214 selects the car 200-2 as an assigned car, and the landing destination floor registration apparatus 400-2 is displayed.

  Further, the same hoistway operation management means 214 instructs the car operation control means 215 to respond to the registered landing destination call. The car operation control means 215 instructed to respond controls the car 200-2 based on the landing destination call. The same hoistway operation management means 214 sends a response to the registered landing destination call to the car operation control means 315 which is a car operation control means in each other car control device in the same hoistway. You may instruct. In that case, the car operation control means 315 instructed to respond controls the car 200-2 based on the landing destination call.

  In the landing destination floor registration device 400-1, a landing floor or a destination floor that cannot be accessed by the car 300-1 that is continuing to operate, that is, a floor corresponding to a stop position where the car 200-1 is stopped is registered. In such a case, the operation management means 214 in the same hoistway may enter the destination floor registration device 400-1, such as "Please enter the destination floor with another registration device" or "Please enter the destination floor with the right registration device". Then, message display or voice guidance for performing the landing floor registration and the destination floor registration with the other landing destination floor registration devices 400-2 to 400-n is performed.

  As another landing destination floor registration device, when a hoistway is further provided, in the landing destination floor registration device (for example, landing destination floor registration device 400-3 not shown) in the hoistway, the landing floor registration is performed. In addition, it may be guided to perform destination floor registration. In addition, you may specify the landing destination floor registration device of the destination, in which case it is installed on the same floor as the floor where the landing destination floor registration device that currently performs the landing floor registration and destination floor registration is installed Specifying a landing destination floor registration device is desirable from the viewpoint of travel distance and the like.

  In addition, by connecting via a network to a landing destination floor registration device in another hoistway, the hoistway that is accessible to both the registered landing floor and the destination floor is searched, and the landing floor in the hoistway is searched. Registration and destination floor registration can be set automatically. For example, if the destination floor registered by the landing destination floor registration device 400-1 is the top floor that is not accessible because the car 300-1 is stopped, the landing floor is registered from the landing destination floor registration device 400-2. Registration and destination floor registration can be automatically performed and the car 300-2 can respond.

  Here, when an abnormal state of the first communication state is detected, and further, an abnormal state of the second communication state in each inter-car control device communication unit 213 is detected in each inter-car control device communication monitoring unit 216. First, the operation of all the cars in the hoistway where the abnormal state of the second communication state is detected is urgently stopped. Note that each car control device communication monitoring means for detecting an abnormal state of the second communication state is another car control device communication monitoring means (for example, each car control device communication monitoring means 316) in the same hoistway. It may be.

  Next, the above operation will be described in detail with reference to FIGS.

  FIG. 2 shows an example in which two cars respond to a landing destination call in the same hoistway in an abnormal state of the first communication state.

  As shown in FIG. 2, the car 300-1 receives a destination call 321 to the 9th floor and is moving in the uphill direction, and the car 200-1 receives the destination call 222 to the 4th floor and goes down the road. Assume that you are moving.

  Since it is an abnormal state of the first communication state, the elevator group management device 100 cannot manage the cars, and each car operates without grasping the position of each other's car.

  When the distance between the cars is below a predetermined distance, it is necessary to stop the operation in order to avoid a collision. As a result, each car cannot travel in the direction of travel and must stop before reaching the destination floor. This is called a deadlock state.

  Next, the operation of the multicar elevator control system according to the present embodiment will be described using the flowchart of FIG. In particular, the case where the lower car (car 300-1) continues to operate will be described.

  First, in step S101, when the first communication state is a normal state, the assigned car determined by the elevator group management device 100 operates according to the landing destination call.

  Next, in step S102, each car control device periodically checks whether an abnormal state of the first communication state is detected in each communication monitoring unit.

  If the abnormal state of the first communication state is not detected (NO), the process returns to step S101 and the normal elevator operation is continued. If an abnormal state of the first communication state is detected (YES), the process proceeds to step S103.

  Next, in step S103, the group communication abnormality information transmitting means transmits the communication abnormality information to each other car control device in the same hoistway.

  Next, in step S104, each car control device 301-1 in the same hoistway starts operation management of all the cars in the same hoistway. That is, it is set so that all the cars in the same hoistway respond to the landing destination call by the operation management means 214 in the same hoistway.

  Next, in step S105, the same hoistway operation management means 214 appropriately responds to the landing destination call registered in the upper and lower cars. Here, if the registered landing destination call is registered at the time when the first communication state is normal, the elevator group management device 100 manages the distance between the cars and the like. It is possible to respond appropriately. However, if it is registered after the time when the first communication state becomes an abnormal state, there is a possibility that the above-mentioned “deadlock state” or the like may occur, and it may not be possible to appropriately respond. In such a case, only those that can be performed among registered landing destination calls may be implemented.

  Next, in step S106, the operation management means 214 in the same hoistway stops the upper car (the car 200-1) on the uppermost floor after the upper and lower cars respond to all registered landing destination calls.

  Next, in step S107, each car control device 301-1 of the lower car (car 300-1) performs operation management of the same hoistway, processes the registered landing destination call, and continues the operation management.

  Next, in step S108, each car control device communication monitoring means periodically checks whether an abnormal state of the second communication state is detected. If an abnormal state of the second communication state is detected (YES), all the cars in the same hoistway are urgently stopped in step S110.

  On the other hand, if an abnormal state of the second communication state is not detected in step 108 (NO), it is checked in step S109 whether or not the first communication state is a normal state in each group communication monitoring means. . Here, whether or not the first communication state is in a normal state is determined by whether or not the communication status confirmation data from the elevator group management device 100 can be received periodically in each group communication means. Can do.

  If it is not detected in step S109 that the first communication state is normal (NO), the process returns to step S107. If it is detected in step S109 that the first communication state is normal (YES), the process returns to step S101 and returns to normal operation.

<Modification>
When an abnormal condition of the first communication state is detected, the lower car continues to respond to the landing destination call in one hoistway, and the upper car continues to respond to the landing destination call in the other hoistway However, the present invention is not limited to the above combination.

  Further, the landing destination floor registration devices 400-1 to 400-n are installed and connected to all the hoistways. However, in some hoistways, the landing destination floor registration devices 400-1 to 400n are installed and connected. It does not have to be.

  At this time, in the hoistway to which the landing destination floor registration devices 400-1 to 400-n are not connected, when an abnormal state of the first communication state is detected, all the cars in the hoistway can be stopped. .

  In the present embodiment, a case has been described in which the abnormal state of the first communication state is detected in the communication monitoring means 211 of each group of the car control devices 201-1 to 201-n. Even when each group communication monitoring unit 311 detects an abnormal state of the first communication state, the same operation can be performed.

  In this embodiment, each group communication monitoring means monitors the first communication state of each group communication means, and if an abnormal state of the first communication state is detected, operation management is performed by the same hoistway operation management means. It was decided to do.

  However, in an abnormal state due to the failure of the elevator group management device 100, group management failure information indicating that the elevator group management device 100 has failed is transmitted to each car control device, and each group communication means transmits group management failure information. When each of the groups is received, each communication monitoring unit may determine the abnormal state of the first communication state and transmit the communication abnormality information from each group of communication abnormality information transmitting unit.

  In this embodiment, when an abnormal state of the first communication state is detected by each communication monitoring means, any one of the same hoistway operation management means in each car control device in the same hoistway will continue operation. Is determined to be the assigned car, but it is also possible that the preset operation management means in the same hoistway determines the assigned car.

  Although two cars are traveling independently on the same hoistway, it may be a case where three or more cars are traveling independently on the same hoistway.

  In this case, communication between the car control devices is formed so that communication can be made between the car control devices of all the cars in the same hoistway. When an abnormal state of the first communication state is detected, at least one hoistway causes the uppermost car to continue operation, and at least one hoistway causes the lowermost car to continue operation. Can be.

  By continuing the operation of the car located at the top or bottom, the stop position of the car that has been stopped can be gathered up or down in the hoistway, allowing the range of operation of the car to continue operation It can be secured as widely as possible. However, the stop position is not limited, and the operation of the car located between the upper and lower cars in the hoistway (for example, the second car in the case of having three cars) is continued, The upper car may be stopped on the top floor and the lowest car may be stopped on the bottom floor.

  It should be noted that although a plurality of cars travel independently on all hoistways, only a single car may travel on some hoistways. That is, the number of cars in each hoistway in the multi-car elevator system need not be unified, and a hoistway in which one car travels may be included.

  In this case, when an abnormal state of the first communication state is detected in the hoistway on which one car travels, each car control device manages the operation of the only car and continues the operation.

  In addition, when each group communication monitoring means 211 of each car control device 201-1 to n detects an abnormality, only one of the upper car and the lower car continues to operate. When a backup function equivalent to 100 call assignment means 101 is provided in each car control device 201-1 to 201-n, and when each group communication monitoring means 211 of each car control device 201-1 to 20-n detects an abnormality, A backup function equivalent to the call assignment means 101 provided in each car control device 201-1 to 201-n determines the assigned car, and when an abnormality is detected in each communication monitoring means 211, the upper and lower cars continue to operate. Also good.

  In this case, the position / speed information of other cars in the same hoistway is acquired through the communication means 213 between the car control devices, the assigned car is determined, and the operation management is performed for each other car from the communication means 213 between the car control devices. I do.

<Effect>
According to the embodiment of the present invention, in the multi-car elevator control system in which the car 200-1 and the car 300-1 travel independently in the same hoistway, each car control device that controls the car operation. And an elevator group management device 100 that adjusts the operation between the car 200-1 and the car 300-1.

  Each car control device 201-1 includes a group communication monitoring unit 211 that monitors a first communication state that is a communication state between each car control device 201-1 and the elevator group management device 100, and each group communication monitoring unit. In 211, when it is determined that the first communication state is an abnormal state, the communication abnormality information transmitting unit 212 that transmits the communication abnormality information to each car control device in the hoistway and the communication abnormality information are received. The same hoistway operation management means 214 that can operate only one car in the hoistway.

  According to such a multi-car elevator control system, even when the first communication state becomes an abnormal state, communication with the elevator group management device 100 is not required, and within the same hoistway provided in each car control device The operation of the car can be continued by the operation management means 214.

  In other words, because the number of cars that continue to operate is limited to one, grasping the position of each car and adjusting the distance between the cars that are operating when multiple cars are operated simultaneously, etc. There is no need to carry out the operation, and the operation of the car can be continued.

  Further, according to the embodiment of the present invention, in the multi-car elevator control system, the same hoistway operation management means 214 stops other cars other than one car that can be operated at a predetermined stop position. Let
