Description

Technical Field

[0001] The present invention relates to the technical field of construction elevator control, and in particular to an elevator intelligent driving double-cage dispatching system. Background Art

[0002] Currently, construction elevators on the market are generally double-cage, with external floor call devices. There is a floor call host in each cage and a call extension on each floor. After the floor station calls, the two call host machines respond at the same time, and drivers on both sides are likely to arrive at the floor at the same time, causing unnecessary waste of electricity. At the same time, the call response is entirely based on the driver's wishes, which can easily cause subjective delays.

[0003] There are also certain risks in using construction elevators. Because they carry a mixture of passengers and cargo, operate in open air conditions, have a harsh working environment, and have many uncertain factors, they are also one of the major sources of danger at construction sites. In view of this situation, the cage of the construction elevator must be equipped with a full-time driver to perform cage lifting operations. Generally speaking, a construction elevator must be equipped with at least three full-time drivers, one for each of the two cages, and another for shift changes. For this reason, the cost of using traditional construction elevators is relatively high. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the present invention provides an intelligent driving double-cage dispatching system for an elevator, which solves the problem that the cage of the existing construction elevator must be equipped with a full-time driver to perform the cage lifting operation. Generally speaking, a construction elevator must be equipped with at least three full-time drivers, one for each of the two cages and the other for shift adjustment. For this reason, the traditional construction elevator has a high cost of use.

[0006] (II) Technical solution

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A double-cage dispatching system for intelligent driving of an elevator comprises a base station control box, a cage, a drive controller, a floor external call box, an electric lock, a number identifier, a weighing sensor and a detection unit. The base station control box comprises a base station control mainboard and a base station wireless transceiver module connected to the base station control mainboard. An in-cage control system is arranged in the cage. The in-cage control system comprises a logic control mainboard and an in-cage wireless transceiver module connected to the logic control mainboard. The in-cage wireless transceiver module establishes a wireless connection with the base station wireless transceiver module for data exchange. The drive controller is arranged in the cage. The drive controller is connected to the logic control mainboard to control the cage to rise or fall. The floor external call box is arranged on each floor of the building. The electric lock is arranged on the floor door. The electric lock is connected to the floor external call box. The number identifier, the weighing sensor and the detection unit are all arranged in the cage. The number identifier and the weighing sensor are both connected to the detection unit.

[0009] Furthermore, the drive controller is connected to the base station control box for data exchange, which is used to call the cage to run to the floor where the floor call box is located. The floor call box can send an unlocking command or a locking command.

[0010] On the basis of the above scheme, the electric control lock is used to receive and execute the unlocking or locking instructions sent by the floor call box.

[0011] As a further solution of the present invention, the dispatching system also includes a position sensor, which is arranged in the cage and is connected to the logic control main board or the drive controller signal for automatic leveling of the cage.

[0012] Furthermore, the base station control box is arranged on the first floor, and the base station control box also includes an outbound call button connected to the base station control mainboard, and the outbound call button is used for calling the elevator on the first floor.

[0013] On the basis of the above scheme, the base station control mainboard adopts an MCU chip, and its software has a built-in elevator scheduling algorithm. The base station control mainboard has a multi-channel communication interface for connecting to the base station wireless transceiver module and the floor call box and performing data interaction. The base station control mainboard also has I / O input and output terminals for connecting the call button.

[0014] As a further solution of the present invention, the detection unit detects the weight W of the load in the cage through a weight sensor, and the detection unit detects the number of people P in the cage through a number recognition device.

[0015] Furthermore, when P=0 and W=0, the construction elevator does not respond to the floor selection in the cage, but only responds to the call outside the cage according to the scheduling principle. When Prated>P>0 and Wrated>W>0, the construction elevator responds to the floor selection in the cage and the call outside the building. When Prated=P and Wrated≥W>0 or Wrated=W and Prated≥P>0, the construction elevator does not respond to the call outside the cage, but only responds to the floor selection in the cage according to the scheduling principle.

[0016] The beneficial effects of the present invention are:

[0017] 1. The present invention is different from the traditional driver-operated mode, which completely relies on the tacit cooperation between the left and right cage drivers. Even experienced drivers cannot avoid inefficient repetitive driving. This control system uses the base station control box as a signal relay transmission link, so that the floor external call box and the cage control system in the cage can exchange data, and send instructions to the electric lock through the floor external call box to realize the intelligent unlocking and locking of the electric lock, and realize the intelligent unmanned driving of the construction elevator; the base station control mainboard registers the elevator call request after receiving the external call instruction, and optimally dispatches the elevator according to the elevator scheduling algorithm in the mainboard. Compared with traditional manual operation, it improves the rationality of elevator dispatching and greatly improves the cage transportation efficiency.

[0018] 2. In the present invention, the cage and the base station control box adopt wireless transmission to realize point-to-point and point-to-multipoint data interaction, which is well adapted to the application scenario of construction elevators. Since the construction elevator is installed on the facade of the building and the operating channel is open, when using wired transmission, the cable is easily disconnected by external objects. Unlike the traditional indoor elevator that uses a closed shaft wired cable transmission method, the elevator needs to be transferred multiple times and repeatedly installed. Therefore, it is more convenient to use wireless transmission for external call signals and data interaction between the two cages.

[0019] 3. The present invention incorporates the elevator load and the number of people in the cage into the scheduling principle, making the scheduling principle more complete. After being called from outside the cage, the elevator automatically reaches the floor, increasing the elevator operation efficiency. At the same time, compared with the traditional leveling by visual inspection, the present invention greatly reduces the labor intensity of the staff. BRIEF DESCRIPTION OF THE DRAWINGS
