PURPOSE:To avoid system down by dividing the group management control function into the control processes which can be executed independently and in which rearrangement is permitted and carrying out each process load allotment independently in autonomy by the scheduling function. CONSTITUTION:The unit body control parts 11a-11n corresponding to the respective machines and the group management control parts 10a-10m for the scheduling management by an operation system are connected by a high speed transmission system 1 having the uniform transmission/receiving priority, and a data field in the hierarchy structure consisting of two systems is constructed. The group management control parts 10a-10m connects the low speed transmission system 2 in each getting-on floor calling transmission control part 4 and process-divides the group management control function into the machine unit group management control function in n-series, and each control part judges the partial charge of process in autonomy by the scheduling management function, and each machine unit group management control function allows each process to judge in autonomy the answer for the getting-on floor call in cooperation under the real time operating system management. Thus, system down can be avoided. |
