23. MICROPROCESSOR GROUP SUPERVISORY CONTROL:

23.1 Microprocessor Group Automatic Control: The microprocessor dispatching shall be based on an advanced 16 bit microprocessor computer system that continuously scans and analyzes every elevator's changing position, condition and workload. It shall compute the potential arrival of every car in REAL TIME; it shall assign and reassign hall calls to the car that can arrive there the quickest. Supervisory and individual controllers shall be of the floor mounted, free-standing type with NEMA 1 enclosures, with locking cabinet doors.

23.2 REAL TIME Management” REAL TIME management of the dispatching shall permit the microprocessor to forecast the requirements for elevator service. The following elevator system information shall be taken into account to calculate the time required for each of the cars to travel to a hall call. The car with the MINIMUM RESPONSE TIME is dispatched to the hall call.

ETA System Information:

A. Elevator in or out of service

ELECTRIC ELEVATORS 14210 - 21

B. Elevator in bypass mode

C. Elevator at lobby in NEXT mode

D. Direction and position of each elevator

E. Condition of the car doors: open, closed, opening, or closing.

F. Condition of each elevator: accelerating, full speed, decelerating.

G. Number of stops required due to car calls

H. Coincident car calls

I. System conditions: up peak, down peak

J. Predictive car and hall call assignments. For example, in most instances, an up-hall call causes a consequential car call to be registered. Forecasting future call movement in this manner gives the processor a more accurate "picture" of the developing traffic.

23.3 All of the above data shall be continuously scanned and hall calls shall be reassigned if the conditions change and another car can respond faster.

Assignments shall be made at a rate f up to 16 times per second thus reflecting changes in the traffic on a REAL TIME basis.

23.4 Operation:

A. Heavy Up Incoming Traffic Conditions: The microprocessor shall automatically recognize heavy incoming traffic in the morning, as well as other times during the day, by monitoring changes in car passenger loads, the number of car calls registered, and the frequency of cars departing the lobby.

The incoming traffic intensity shall determine the number of cars assigned to the lobby. The system shall recognize the increasing incoming traffic early and react in a controlled manner.

23.5 Once a car completes its up trip after it has answered its car calls and any up-hall calls assigned to it, it shall then reverse and proceed to the lobby floor, provided the system is still in heavy up. The assignment of these up and down hall calls is described in the following paragraph.

23.6 When the incoming traffic becomes lighter, the microprocessor shall allocate cars from the lobby accordingly. The other cars park with their doors closed at the landing they last served.

23.7 Select Hall Waiting Time (Up Peak): The up and down hall call response time

ELECTRIC ELEVATORS 14210 - 22

shall be preset so that these calls can be answered in an adjustable minimum/maximum time interval, permitting better service to the incoming traffic.

When this feature is enabled, the microprocessor shall calculate the potential arrival of each car and assign or reassign the up and down hall calls (with the exception of the lobby floor) to the car that meets the selected service requirements, and not necessarily to the car with the best potential arrival time. If the calculated ETA's do not satisfy the minimum/maximum time interval, microprocessor shall assign the call to the car having its ETA closest to the minimum selected service. This feature shall be implemented on a per floor basis.

A. Heavy Down Traffic Conditions. The microprocessor shall automatically recognize heavy ongoing or down traffic by monitoring the number of down hall calls, their ETA, and the actual waiting time. During this mode, the down hall calls shall be given preferential service to handle the traffic which can occur in the evening or other time during the day. All cars assigned to the lobby floor shall be released. Cars arriving at the lower dispatching terminal shall light their lantern and remain at the terminal for the same length of time as for any other floor. all down hall calls are assigned based on which car has the best potential arrival time. The assignment of the up-hall calls is described in the following paragraph. Down peak traffic mode shall have priority over up peak.

23.8 Select Hall Waiting Time (Down Peak): The up hall call response time shall be preset so that these calls can be answered in an adjustable minimum/maximum time interval permitting better service to the outgoing traffic. The assignments shall be made the same way as under "Select Hall Waiting Time (Up Peak)" but for the up hall calls only.

23.9 Two-way Traffic…
