Problems solved by technology

[0004] However, in the method described above, when the group management control is performed using the average waiting time as an index, there is actually a problem that it is impossible to know exactly how much power saving effect is obtained.
Moreover, even when the target value of power consumption is used as an index, it will become an unclear index such as operating with 80% of the current power, and it is difficult to grasp the actual power saving effect.

no. 1 Embodiment

[0036] figure 1 It is a block diagram showing the configuration of the elevator group supervisory control system according to the first embodiment of the present invention.

[0037] The group management control system of the elevator in the present embodiment comprises: target power setting device 11, group management control device 12, power consumption measurement device 13, single control device 14a, 14b, 14c..., passenger car 15a , 15b, 15c..., call buttons 16a, 16b... at the elevator place, and display devices 17a, 17b... for the number of working tables.

[0038] The target power amount setting device 11 is installed in a building monitoring room or an elevator machine room, and is connected to a group supervisory control device 12 . The target power amount setting device 11 includes, for example, a personal computer, etc., and various target values ​​(power consumption, power saving period) related to electrification can be arbitrarily set by a building manager (includ...

no. 2 Embodiment

[0093] Next, a second embodiment of the present invention will be described.

[0094] Its basic structure is the same as that of the above-mentioned first embodiment figure 1 same. In the second embodiment, the items that can be set by the target power amount setting device 11 are different.

[0095] that is, if Figure 8 As shown, in the setting item 51 provided on the setting screen 50, as the target value, in addition to the period during which power saving is implemented and the amount of use-permitted power allowed to be consumed during this period, the limit of the average waiting time can also be set arbitrarily. value and which of the limit value of the permitted power amount and the average waiting time should be prioritized for power saving.

[0096] In addition, in the display item 52 provided on the setting screen 50 , the current daily power consumption acquired from the power consumption statistics unit 21 via the number of operating machines control unit 23 a...

no. 3 Embodiment

[0109] Next, a third embodiment of the present invention will be described.

[0110] In the third embodiment, when there is a difference of more than a certain amount between the planned power consumption amount and the actual power consumption amount during the power saving implementation period, the number of operating machines is replanned and implemented during the remaining period.

[0111] Furthermore, the basic structure is the same as that of the first embodiment, as figure 1 structure shown in. In the third embodiment, when the actual power consumption during the power-saving implementation period is different from the plan, the number of workstations control unit 23 in the third embodiment may reconsider the planning of the number of workstations so as to satisfy the use-permitted power amount during the remaining power-saving implementation period. .

[0112] Here, use Figure 10 The processing flow when the planning of the number of tables is reconsidered in the...

Abstract

The invention provides a group control system of elevators. Target value of electric power consumption in the appointed period of time is set by a target electric power setting apparatus. An electric power consumption statistical section is arranged on a group management control apparatus, and records each elevator consumed electric power and average latency according to every preset time period in a statistical mode. A working number control section, is equipped for planning working number of elevator in every time period for obtaining target value according to target value of consumed electric power set by the target electric power setting apparatus as well as consumed electric power and average latency in every time period obtained by the electric power consumption statistical section.A group management control section is arranged for controlling operation of each elevator called at the elevator riding point according to working number in every time period planned by the working number control section.

Description

technical field [0001] The invention relates to an elevator group management control system for group management control of multiple elevators, in particular to an elevator group management control system for saving power by controlling the number of working elevators. Background technique [0002] In buildings such as offices, a plurality of elevators are generally provided. When a call is registered at a certain floor, the most suitable elevator is selected to respond to the registered floor of the call at the elevator. In this case, although other elevators sometimes stop due to waiting for a call, they are usually in an operating state during this period, and thus consume power. If the number of operating platforms of the elevator increases, the amount of power consumption will increase significantly accordingly, so countermeasures are required. [0003] In the conventional technology, as a method of reducing the power consumption of the whole elevator, for example, in ...
