METHOD OF CONTROLLING THE LIFT SYSTEM - FÖRFARANDE FÖR STYRNING AV ETT HISSYSTEM

The present invention relates to a method for controlling an elevator system according to the preamble of claim 1.

Today, elevator control systems act as a queuing selection or aggregation function. In queuing selection, the elevator is routed to the level specified by the call without serving other calls in between. 10 The use of queuing option significantly reduces the performance of the elevator system and is therefore not good enough to apply to houses where moderate transport capacity and access control are required. In the aggregation function, on the other hand, the elevator serves calls from intermediate levels 15 without access control, thus maximizing the transport capacity of the elevators, but at the same time reducing the level of security as people joining the stops are offered access to potentially locked floors.

The purpose of the method according to the invention is to increase the performance of the elevator control system when using the elevator access control functions. The increase in performance is based on the layer-by-layer and bypassing of locks based on the access rights of different persons or groups of persons stored in the elevator control system and the utilization of access control rights as set out in the claims.

30 The stopping of an elevator on floors equipped with different categories of access, such as those owned or operated by an undertaking, can be decided on the basis of the categories of access for passengers currently in the elevator car. Various commercial personal identification devices, such as card readers or code keypads, can be utilized to identify current elevator users 2 85259 in relation to people in the elevator car and / or floor levels. Based on this information, the operation of the elevator control system can be optimized so that performance increases compared to control principles based on normal queuing selection. However, the security level of the house can be maintained high enough.

The importance of access control is constantly increasing, and the elevator cannot be ignored in connection with access control, because it 10 forms the main passage of the building. If it is not possible to implement an access control function for the elevator that does not reduce the transport capacity unreasonably, the elevators will be excluded from the building's shell protection to a certain extent in the future. This in turn leads to an increase in the other security costs of the building. Properly implemented, elevator access control functions can reduce the security costs required for building security, e.g. reducing the size of elevator lobbies and removing otherwise necessary door access controls in lobbies.

In the following, the invention will be described in more detail by means of examples with reference to the accompanying drawing, in which

Figure 1 shows a selective assembly control according to the invention.

Figure 2 shows a selective assembly control system.

The selective aggregation function is based on the fact that the elevator system-30 always knows the location of each elevator and the floor-specific locking level or group of access rights set for each locked floor.

In Fig. 1, a person 2 enters the elevator car 4 of the elevator 35 in the building 1 for the purpose of driving from floor A to floor F. It is assumed that floors B to E fall along the road. In this case, those who are allowed to walk to floor A are also allowed to walk to floor B. If now, when the elevator is walking towards floor F, there is a parallel call waiting in floor B, the elevator can serve the call of that floor.

If the queuing option according to the prior art were used when running from layer A to layer F, the call between layers 10 would be left unserved, because the queuing selection would first run to layer f, and then take a new call from the call queue to be served.

In the starting floor A, commercially available card readers 3a to 3i or other similar systems can be used to identify the elevator passenger. Personal identification is not necessarily required, but a separate code keypad can be used to enter an identification code that defines the next lock class or access group of the elevator. In addition to the identification at level ta-20, a separate card reader 5 for the identification of a person or a group of passengers in the elevator car 4 can be used.

The stopping of the elevator on different floors can also be allowed when knowing the access categories of people waiting. These categories of access rights can be ascertained by using identification devices for persons on the floor, such as card readers 3a to 3i or code keypads. If people with access rights 30 or higher than those in the car are waiting on the floor deck, the lift can be allowed to stop on that floor.

Figure 2 further shows a control system for selective assembly control according to the invention, in which the group control computer 6 of the elevator system handles the control of the elevator group, and each elevator (ELEVATOR1, ELEVATOR2, ELEVATOR3) has its own control computer 7-9. For access control, the building has an access control system comprising a computer 10 and the card readers 3a to 3i, 5 described above in the elevator car and on the levels for each elevator group and elevator group elevator 5 (shown in Fig. 2 only for elevator ELEVI3). You don't have to place a card reader or code keyboard on every floor.

A card reader or similar device can be connected directly to the elevator 10 or the device may be connected to a separate access control system. Information on the access control classes in the elevator car and the floor lane is transmitted from the access control system to the elevator system using a data transmission connection.

15 The elevator system performs logical data aggregation, in which case the access rights of the people in the elevator car and the service requests of the passengers waiting on the floor are known.

It will be apparent to those skilled in the art that the various embodiments of the invention are not limited to the examples set forth above, but may vary within the scope of the claims set forth below.

Claims (4)

A method for full collective control of a lift system provided with passage control and comprising one or more elevators (7-9) by means of calls from the plan (AJ) and the lift basket (4), which passage control system comprises passenger terminals (3a-3i) , 5) for checking the access of passengers (2) and in which the passenger control system the passengers are divided into access categories, characterized in that the full collective control is done selectively according to authorization category sA, that the elevator is allowed to stop at a piano called while the elevator executes the previous request for elevator pass as high as or higher than the called plane's. 15 Method according to claim 1, characterized in that the selective full-collective control is time-controlled. 3. A method according to claim 1 or 2, characterized in that the passage terminals are located in the plane (A-1) above and / or below the entrance plane and in the elevator car (4) and / or in the entrance plane. Method according to any one of the preceding claims, characterized in that the passage terminals are card readers, code keypads or the like.
