Abstract

1468062 Multi-car systems WESTINGHOUSE ELECTRIC CORP 12 March 1974 [12 March 1973] 10981/74 Heading G3N The disclosure is the same as that of Specification 1468061 but the claims are concerned with strategies for assigning the highest call amongst a group of down floor calls, for clearing the system and re-allocating all floor calls, and for periodic verification that "demand" floor calls, {i.e. those which could not be allocated by subprogram (ACL) Fig. 4 (not shown) to a car already having a floor call service requirement } have an available car assigned to them. If a new, highest down floor call is received, that car which was assigned to the previous highest call has its allocation transferred to the new highest call only if there is no other car without service demands on it to take the new highest call. This strategy is stated to save needless running of cars in comparison with schemes in which a car allocated to a highest down call will automatically be allocated a new highest down call. Whenever, during operation, all cars become free of service demands, car assignment, call, and call change, records are all cleared, any unanswered call being registered as a new call. As a verification any floor call which has had an available car assigned to it { by sub-program (ACR) Fig. 4 (not shown) is periodically treated as a new call and reprocessed as a new "demand".
