Based on the hardware structure, the embodiment of the control method for the elevator return base station is provided.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a control method of an elevator return base station, the method comprising:
step S10, after the power grid is cut off, the generator is started, and a generator working signal is output to each single-ladder control system through the generator, so that each single-ladder control system enters a generator power supply mode according to the received generator working signal;
the control method of the elevator return base station is applied to the control systems of the elevator return base stations in the office areas, the residential areas and other areas, and for convenience in description, the control system of the elevator return base station is referred to as a master control system for short. In order to improve the safety and reliability of elevators, a generator or a backup power supply is generally provided to supply power to elevators in a building, so as to prevent elevator distress from occurring when the voltage of a power grid fluctuates or the power grid is cut off. However, when the elevator is managed by the property department at present, the group control system is generally used for controlling the elevators to return to the base station one by one, and because the whole group control system is in a star-shaped topological structure and is a control center, when the group control system fails or communication failure occurs between the group control system and a single elevator, at most one elevator can not be ensured to operate at any time, so that the reliability of the system is low. In addition, there is also a power time-sharing multiplexing scheme, after the power failure of the building, each single-elevator control system is allocated a fixed time to supply power, that is, no matter whether the current single-elevator control system completes the corresponding return operation within the time, as long as the power supply time of the single-elevator control system is over, the power supply for the single-elevator control system is stopped, but this scheme cannot ensure that only one elevator at most operates at any time, resulting in low reliability of the system.
In the embodiment, in order to improve the reliability of the system, an overall control system of a ring topology is designed, and the overall control system of the ring topology is as shown in fig. 3. The master control system comprises a generator and a plurality of single-ladder Control Systems (MCBs), and each single-ladder control system at least comprises two input ports and one output port. If two input ports used by each single-ladder system are respectively an X1 port and an X2 port, and the used output port is a Y port, the output port of the generator is respectively in communication connection with the input port X2 of each single-ladder control system, the output port Y of the previous single-ladder control system is in communication connection with the input port X1 of the next single-ladder control system, wherein the X2 port of each single-ladder control system is used for receiving a generator working signal sent by the generator; the X1 port is used for receiving a return instruction sent by a previous single-elevator control system in the ring topology structure so as to inform the single-elevator control system to execute a return operation corresponding to the return instruction; the Y port is used for sending a return instruction to the next single-elevator control system.
As shown in fig. 3, if the master control system includes n single-ladder control systems, the Y port of the first single-ladder control system (MCB1) is communicatively connected to the X1 port of the second single-ladder control system (MCB2), the Y port of the second single-ladder control system is communicatively connected to the X1 port of the third single-ladder control system (MCB3), and so on, and the Y port of the last single-ladder control system (MCBn) is communicatively connected to the X1 port of the first single-ladder control system, so as to form a ring topology for the individual single-ladder control systems. Specifically, after the building is powered off, the generator is started, and a generator working signal S _0 is sent to each single-ladder control system through an output port of the generator; when the X2 port of each single-elevator control system receives the S _0 signal, each single-elevator control system enters a generator power supply mode from a normal power grid power supply mode. Because the return operation is executed by only one single-ladder control system at any time, after each single-ladder control system enters a power supply mode of the generator, the base station return process can be sequentially executed by each single-ladder control system according to the receiving time sequence of the return instruction.
Further, before the step of sequentially executing the base station return procedure by each single-ladder control system, the method further includes:
step a1, detecting whether the elevator corresponding to each single-elevator control system has operation failure within preset time;
step a2, if there is no operation fault in the corresponding elevators of each single-elevator control system, sequentially executing a base station returning process by each single-elevator control system so as to return the corresponding elevators of each single-elevator control system to the corresponding preset base station positions one by one.
In this embodiment, a detection time is preset to ensure that the total control system is in a normal working state within the detection time after the generator starts working, that is, all elevators corresponding to the single-elevator control system have no operation fault. In addition, after the power grid is powered off, the generator is not only used for returning each elevator to a preset base station position, but also needs to supply power for other service modules, and when the generator just starts to work, the voltage of the power supply is unstable, so that all elevators corresponding to the single-elevator control system are ensured to have no operation fault within the set detection time, and the reliability of the master control system can be improved.
And step S20, after each single-ladder control system enters a generator power supply mode, sequentially executing a base station returning process through each single-ladder control system so as to return the corresponding elevators of each single-ladder control system to the corresponding preset base station positions one by one.
In this embodiment, the preset base station position refers to a landing where an elevator stays when there is no call signal, and is generally a floor with the highest use frequency, but the preset base station positions corresponding to different elevators can be set according to actual application requirements. When each single-elevator control system is detected to enter a power supply mode of the generator, the return operation executed by the single-elevator control system and the sent return instruction are related to the state and the ID of the current corresponding elevator, wherein the return operation comprises a floor return operation and a base station return operation, the return instruction comprises a floor return instruction and a base station return instruction, the state of the elevator comprises a normal running state and a running obstacle state, and the ID of the elevator is increased from 1 in sequence according to the wiring sequence in the annular topological structure. For example, if the master control system includes n single-elevator control systems, and each elevator is in a normal state, the Y port of the first single-elevator control system is connected to the input port X1 of the second single-elevator control system, the Y port of the second single-elevator control system is connected to the input port X1 of the third single-elevator control system, and so on, and the Y port of the nth single-elevator control system is connected to the input port X1 of the first single-elevator control system, then the ID of the first elevator corresponding to the first single-elevator control system is 1, the ID of the second elevator corresponding to the second single-elevator control system is 2, and so on, the ID of the nth elevator corresponding to the nth single-elevator control system is n, after the return operation of the elevator with ID of 1 is completed, the corresponding return instruction can be sent to the second single-elevator control system, the elevator with ID of 2 is controlled to perform the corresponding return operation, and so on, until the elevator with ID of n completes the corresponding return operation, and sending a corresponding return command to the first single-elevator control system to control the elevator with the ID of 1 to execute the next return operation or complete the base station return process. In addition, for cost reasons, the backup power supply or generator typically provided for an elevator is not sufficient for multiple elevators to operate simultaneously, so that at any one time only one single-elevator control system is performing the return operation. When the base station returning process is executed, corresponding returning operation is executed sequentially through the single-elevator control systems according to the instruction transmission direction in the ring topology structure, so that the elevators corresponding to the single-elevator control systems are returned to the corresponding preset base station positions from the initial staying current positions one by one.
According to the control method for returning the elevator to the base station, after the power grid is powered off, the generator is started, and the generator working signals are output to each single-elevator control system through the generator, so that each single-elevator control system can enter a generator power supply mode according to the received generator working signals; and after each single-ladder control system enters a power supply mode of the generator, sequentially executing a base station returning process through each single-ladder control system so as to return the corresponding elevator of each single-ladder control system to the corresponding preset base station position from the current position one by one. The invention returns each elevator to the corresponding base station position one by one through the control system of the ring topology structure, thereby improving the reliability and the safety of the control system.
Further, based on the first embodiment of the control method of the elevator return base station of the invention, a second embodiment of the control method of the elevator return base station of the invention is provided.
The second embodiment of the control method of the elevator return base station is different from the first embodiment of the control method of the elevator return base station in that step S20 further includes:
b1, when the base station returning process is executed, the single-ladder control systems sequentially execute the leveling returning operation so as to return the elevators corresponding to the single-ladder control systems to the corresponding leveling positions one by one;
and b2, when it is detected that the single-ladder control systems finish the floor-returning operation, sequentially executing the base station-returning operation through the single-ladder control systems so as to return the elevators corresponding to the single-ladder control systems to the corresponding preset base station positions from the floor-returning positions one by one.
In this embodiment, since the power failure of a building generally belongs to an emergency, passengers generally remain in the elevator after the power failure of the power grid of the building, and therefore, in view of the safety of elevator passengers, it is necessary to sequentially perform a floor leveling return operation through each single-elevator control system, and return each elevator to a floor leveling position one by one, where the floor leveling position is a floor position closest to the current elevator stop position or a nearest floor position in the same direction as the base station; when each elevator returns to the corresponding flat floor position and opens the elevator door, the passengers trapped in the elevator can sequentially execute the operation of returning to the base station through each single elevator control system after falling behind safely during power failure, and each elevator returns to the corresponding preset base station position one by one.
Further, step b1 further includes:
step b11, sending a leveling instruction to a preset first single-ladder control system;
b12, when the first single-lift control system receives a floor-returning instruction, determining the current position of a corresponding first elevator through the first single-lift control system, and determining a first floor position corresponding to the first elevator according to the current position, so that the first single-lift control system controls the first elevator to return to the first floor position from the current position, and the floor-returning operation of the first single-lift control system is completed;
b13, when detecting that the first single-ladder control system finishes the operation of returning to the leveling floor, sending a leveling floor returning instruction to the next single-ladder control system through the first single-ladder control system, so that the leveling floor returning single-ladder control system receiving the leveling floor returning instruction executes the leveling floor returning operation;
and b14, after the single-ladder control system of the leveling return layer completes the corresponding leveling return operation, notifying the corresponding next single-ladder control system to execute the leveling return operation through the single-ladder control system of the leveling return layer until the last single-ladder control system in the ring topology structure completes the corresponding leveling return operation.
In this embodiment, since only one elevator is in operation at any time, the operation sequence of each single-elevator control system needs to be preset, and the single-elevator control systems are in communication connection in sequence according to the operation sequence, so as to construct a master control system with a ring topology structure. Specifically, if in the process of executing the procedure of returning to the base station, each elevator has no operation obstacle, the single-elevator control system which executes the procedure of returning to the base station first is the first single-elevator control system, and the elevator corresponding to the first single-elevator control system is the first elevator, then the specific procedures of sequentially executing the operation of returning to the leveling floor by each single-elevator control system are as follows: the main control system sends a leveling return instruction to the first single-elevator control system, and when the first single-elevator control system receives the leveling return instruction, the leveling return operation is executed to return the first elevator to the corresponding leveling position; after the first elevator is finished with the floor-returning operation, the first elevator stops running and sends a floor-returning command S _1 to a next single-elevator control system (MCB2) through a Y port of the MCB 1; when the MCB2 receives the floor leveling instruction, the MCB performs floor leveling operation to return the second elevator to the corresponding floor leveling position; after the MCB2 rebalancing operation is completed, sending a rebalancing instruction to the MCB3 through the MCB2 to inform the MCB3 to perform the rebalancing operation; by analogy, the MCBs 3 through MCBn repeat the above leveling operation steps in sequence until all elevators return to the corresponding leveling positions.
The flow of each single-ladder control system when performing the floor-returning operation is similar, taking the MCB1 as an example for performing the floor-returning operation. When the MCB1 receives a floor return command, the current position of the first elevator is determined, that is, the position where the first elevator stops operating after the MCB1 enters the power supply mode of the generator, and then the floor return position of the first elevator is determined according to the current position, for example, if the current position of the first elevator is a position between the 5 th floor and the 6 th floor of the building, the nearest floor position of the first elevator can be determined by comparing the distance between the first elevator and the floor 5 position and the distance between the first elevator and the floor 6 position, so that passengers can safely reach the nearest floor position at the fastest speed; the corresponding floor leveling position can also be determined according to the relative direction of the current position of the first elevator and the preset base station position, for example, the preset base station position of the first elevator is 7 floors, and if no passenger is detected in the first elevator, the floor leveling position of 6 floors can be used as the floor leveling position to be returned by the first elevator, so that the power supply is saved, and the base station returning of other elevators is guaranteed. When the MCB1 is detected to finish the floor-returning operation, a floor-returning command is sent to the next single-elevator control system through the output port of the MCB1, so that the corresponding elevators are sequentially returned to the corresponding floor-returning positions through each next single-elevator control system.
It should be noted that when passengers are detected in the elevator, the elevator can be preferentially returned to the leveling position closest to the current stopping position of the elevator, and then a leveling return instruction is sent to the next single-elevator control system through the corresponding single-elevator control system, so that the passengers in the elevator can be ensured to reach the safe leveling position most quickly.
Further, step b2 further includes:
b21, when the first single-ladder control system receives a base station returning instruction, controlling the first elevator to return to a corresponding first preset base station position from the first floor position through the first single-ladder control system according to the base station returning instruction, and completing the base station returning operation of the first single-ladder control system;
step b22, when it is detected that the operation of returning to the base station of the first single-ladder control system is completed, sending a base station returning instruction to a next single-ladder control system through the first single-ladder control system, so that the base station returning single-ladder control system receiving the base station returning instruction executes the base station returning operation;
step b23, after the base station returning single-ladder control system completes the corresponding base station returning operation, the base station returning single-ladder control system notifies the corresponding next single-ladder control system to execute the base station returning operation until the last single-ladder control system in the ring topology structure completes the corresponding base station returning operation.
In this embodiment, when it is detected that the MCBn completes the corresponding floor return operation, on one hand, the floor return instruction may be sent to the MCB1 through the MCBn, and then, when the MCB1 receives the floor return instruction sent by the MCBn, the floor return instruction received again by the first single-ladder control system is converted into the base return instruction, on the other hand, the base return instruction may also be sent to the first single-ladder control system through the general control system, and when the first single-ladder control system receives the base return instruction, the first elevator is controlled to return from the first floor position to the corresponding first preset base station position according to the base return instruction, so as to complete the base return operation of the first single-ladder control system, and then the base return operation is performed sequentially through the subsequent single-ladder control systems, so as to return the elevators from their respective floor positions to the corresponding preset base station positions, and the operation flow when the base return operation is performed through the respective single-ladder control systems and the operation flow when the respective single-ladder control systems perform the floor return operation The process is similar and will not be described herein.
According to the control method for the elevator returning base station, the single elevator control systems execute the operation of returning to the leveling layer to return the elevators to the corresponding leveling positions one by one, then the single elevator control systems sequentially execute the operation of returning to the base station to return the elevators to the corresponding preset base station positions one by one, the safety of elevator passengers is guaranteed, and meanwhile the reliability of the master control system can be improved.
Further, a third embodiment of the control method of the elevator return base station of the present invention is proposed based on the first and second embodiments of the control method of the elevator return base station of the present invention.
The third embodiment of the control method of the elevator return base station is different from the first and second embodiments of the control method of the elevator return base station in that if at least one elevator corresponding to the single-elevator control system is in an operation failure state, the step of sequentially executing the process of returning to the base station by each single-elevator control system comprises the following steps:
and c, in the process of executing the base station returning process, when a target single-elevator control system corresponding to the elevator in the operation failure state is detected to receive a return instruction sent by a previous single-elevator control system, sending the return instruction to a corresponding next single-elevator control system through the target single-elevator control system, so that the single-elevator control system receiving the return instruction sends the return instruction to the corresponding next single-elevator control system or controls the corresponding elevator to return to the leveling position/preset base station position corresponding to the return instruction.
In this embodiment, since there is a possibility that an operation obstacle of the elevator occurs when the floor return operation/base station return operation are sequentially performed by the respective single-elevator control systems, that is, the elevator having an operation obstacle during the operation of the backup power supply may not perform the floor return operation or the base station return operation, the return instruction may be a floor return instruction or a base station return instruction. When a target single-elevator control system corresponding to the elevator in the operation obstacle state receives a leveling return instruction or a base station return instruction, the received return instruction is not executed, but the target single-elevator control system can execute a completed logic according to the current instruction, and sends a corresponding return instruction to a next single-elevator control system through a Y port so as to sequentially send the return instruction to the next single-elevator control system through the previous single-elevator control system until all elevators in the normal operation state in the master control system return to corresponding preset base station positions, and then the elevator in the operation obstacle state is continuously waited to recover from the fault and return to the corresponding preset base station positions, so that the elevators in the master control system are returned to the corresponding preset base station positions one by one.
According to the control method for the elevator returning base station, when the elevator which does not return to the preset base station position is in the operation obstacle state, the single elevator control system corresponding to the elevator still sends the returning instruction to the next single elevator control system, so that the reliability of the master control system is ensured, and meanwhile, the efficiency of returning other normal operation elevators to the preset base station position is improved.
Further, based on the first, second and third embodiments of the method for controlling an elevator return base station of the present invention, a fourth embodiment of the method for controlling an elevator return base station of the present invention is provided.
The fourth embodiment of the control method of the elevator return base station is different from the first, second and third embodiments of the control method of the elevator return base station in that the step of sequentially executing the return base station flow by each single-elevator control system comprises:
step d1, when an elevator fault recovery command is received, determining a target elevator which is recovered to a normal state from an operation fault state and a to-be-determined single elevator control system which currently executes a return operation;
d2, sending a return prohibition instruction to the corresponding next single elevator control system through the single elevator control system corresponding to the target elevator, so that the single elevator control system receiving the return prohibition instruction stops the current return operation;
step d3, when the single-ladder control system receiving the instruction for prohibiting return is a preset first single-ladder control system, converting the instruction for prohibiting return received by the first single-ladder control system into a return instruction again, and sequentially sending the return instruction again to a next single-ladder control system from the first single-ladder control system;
and d4, when the single-elevator control system corresponding to the target elevator receives a return command sent by the previous single-elevator control system, returning the target elevator to the corresponding flat floor position or the preset base station position, and informing the single-elevator control system to be determined to continue to execute the corresponding return operation so as to complete the base station return process.
In this embodiment, since the elevator that has just recovered from the operation obstacle state to the normal operation state has not returned to the corresponding leveling position or the corresponding preset base station position, and there may be other single-elevator control systems currently executing the corresponding return operation, when receiving the elevator fault recovery instruction, it is necessary to determine the elevator that has recovered from the operation obstacle state to the normal operation state, that is, the target elevator, and the pending single-elevator control system that is currently executing the return operation. And then, the single-elevator control system corresponding to the target elevator sends a return prohibition instruction to a corresponding next single-elevator control system, so that each single-elevator control system sequentially receives the return prohibition instruction sent by the previous single-elevator control system, and stops the currently executed return operation to keep the elevator in a static state. For example, when the ith elevator recovers from the fault, the single-elevator control system corresponding to the ith elevator sends a return prohibition instruction to the next single-elevator control system through the Y port; when the single-elevator control system corresponding to the (i + 1) th elevator receives the return prohibition instruction, stopping the currently executed return operation, keeping the elevator in a static state, and sending the return prohibition instruction to the single-elevator control system of the (i + 2) th elevator through the Y port until the MCB1 receives the return prohibition instruction.
When the MCB1 receives the return prohibition command, ensuring that the first elevator is in a static state, and sending a return again command to the MCB2 to inform the MCB2 that the elevator which is recovered from the operation obstacle state to the normal state exists, so that the return again command is transmitted to the next single elevator control system in turn; when the MCB2 receives the return command, the elevator is kept in a static state, and the return command is sent to the MCB3 until the MCB1 receives the return command, and then the steps executed when the fault does not exist are executed again. When the single-elevator control system corresponding to the target elevator receives a re-return instruction sent by the previous single-elevator control system, the target elevator is returned to the corresponding leveling position or the preset base station position, and after the single-elevator control system corresponding to the target elevator completes the corresponding leveling operation/base station return operation, the undetermined single-elevator control system stopping executing the return operation before is informed to continue executing the corresponding return operation, so that the elevators are returned to the corresponding preset base station position from the current positions one by one.
According to the control method of the elevator returning base station, when the target elevator is detected to recover from the operation fault, the single-elevator control system corresponding to the target elevator transmits the instruction of forbidding returning to the next single-elevator control system, so that the other elevators are ensured to execute corresponding returning operation after stopping operation, and the reliability of the master control system can be further ensured; in addition, after the MCB1 receives the return prohibition instruction, the MCB1 sends a restart instruction to the next single-elevator control system, and the target elevator can be controlled to return to the corresponding flat-bed position or the preset base station position without receiving the return prohibition instruction by all the single-elevator control systems, and the undetermined single-elevator control system is notified to continue to execute the corresponding return operation, so that the overall efficiency of returning the elevator to the preset base station position can be further improved.
