In operational process, the dc bus controller is collected the work state information of each on and off switch that matches with each escalator in each staircase and the dc bus controller (as being many gravity flow bus controllers, then collect the work state information of on and off switch in the bus controller that respectively flows automatically), and judge whether each dc bus and the connection of dc bus bus according to collected information; With respect to prior art, dc bus in the time of can moving multiple escalator according to the running condition of each escalator carries out team control, control the break-make of dc bus in each escalator according to the running condition of each escalator and shunt to realize the best, good energy-conserving effect, safety is higher; Particularly, the control process of dc bus can be for following several:
1, if one of them staircase is out of service, then described dc bus controller disconnects the dc bus of described dc bus bus and this escalator;
2, in multiple escalator, if the part escalator is up, the part escalator is descending, the dc bus of then described dc bus controller escalator that this row is up, descending escalator all with described dc bus bus connection; When escalator is descending, motor inverted running and generating electricity, this electric current exports the dc bus bus to by dc bus, and to up escalator power supply; Energy is transmitted, to improve energy-conservation effect to up escalator by descending escalator;
3, in multiple escalator, if each escalator is all descending, then described dc bus controller disconnects the dc bus of described dc bus bus and each escalator;
4, if the described dc bus controller of one of them escalator damages, then this dc bus controller disconnects the described dc bus and the dc bus bus of this escalator.
The further structure of system of the present invention is that the quantity of described dc bus controller is identical with the quantity of described escalator, is equipped with a described on and off switch on each dc bus controller.Can escalator dc bus controller be arranged respectively all, in order to avoid when controlling, have influence on the control of total system if this dc bus controller is damaged, to improve its safety by a total dc bus controller.
Described each dc bus controller is electrically connected mutually.Also realize communication between the dc bus controller of each escalator, obtain the running state of each frequency converter, and the information such as voltage of each dc bus.
Described dc bus controller is electrically connected with described staircase controller.Each dc bus controller obtains the information of the running condition of each escalator from each staircase controller.
The two ends of each described frequency converter DC side are equipped with braking resistor.When each escalator all was in downstream state, the descending electric current that produces of each escalator flows through this braking resistor reduced voltage.
