Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1, fig. 1 shows a system wiring diagram for detecting the door lock of a hoistway door in the power-on state in the safety loop of the current elevator control system. In the detection of the elevator hall door lock shown in fig. 1, the landing door locks of all the floors are sequentially connected in series and then connected into the detection loop of the car door lock and the hall door lock. When the switch of the hall door lock on a certain floor is disconnected, the elevator controller or the main control board can only identify the disconnection of the hall door lock and can not identify the floor position of the disconnected hall door lock, the condition of the switch of the hall door lock needs to be checked layer by layer, and the position of a fault point can not be positioned quickly and accurately.
Referring to fig. 2, fig. 2 is a schematic diagram of an exemplary system architecture to which an embodiment of the elevator safety loop-based door lock detection method of the present application may be applied.
As shown in fig. 2, in the embodiment applied to the door lock detection method based on the elevator safety loop, the elevator safety loop includes: the system comprises a main controller, a plurality of outbound controllers and a plurality of door lock switches corresponding to the outbound controllers respectively.
The main controller is used for controlling the operation of the elevator, so that the elevator can normally operate, and the operation of the elevator is stopped when various faults affecting the safety occur in the operation of the elevator, such as the fault of an elevator door lock; the main controller is the main controller of the elevator running loop and the safety loop. The master controller can be a master command device which controls the starting, speed regulation, braking and reversing of the motor by changing the wiring of the main circuit or the control circuit and changing the resistance value in the circuit according to a preset sequence. The computer system also can be an operating device which is composed of a program counter, an instruction register, an instruction decoder, a time sequence generator and an operation controller and is used for coordinating and commanding the whole computer system. Specifically, the controller may be a control system having a microprocessor, such as a single chip microcomputer control system, a PLC control system, or the like.
The calling controller is used for acquiring floor calling information and displaying the floor and the running information of the elevator. For example, the current floor of the elevator, the up-down direction of the elevator, overload maintenance signals, up-down button information and the like can be displayed, and fault information can also be displayed.
The door lock is arranged at each floor of the elevator operation and used for controlling the opening or closing of the hall door and the car door. The elevator door lock forms a loop through the door lock switch on the elevator door lock for control, so that the door lock is prevented from failing, the elevator is prevented from running accidents under the condition that the car door or the hall door is not closed, and the personnel safety is ensured. In the elevator safety loop, a door lock switch of a door lock is connected into the safety loop, the opening and closing of a car door are detected, the elevator safety loop is conducted after a hoistway door and a car door are completely closed, and a door lock relay is actuated. When any one of the doors is opened, the corresponding door lock switch is disconnected, so that the safety loop is disconnected, and the door lock relay is released, thereby directly controlling the stop and the operation of the elevator.
In the elevator safety loop, the door lock switches of each layer are connected in series, and the head end and the tail end of the door lock switches connected in series are connected to the master controller to form a door lock loop; here, each of the outbound controllers is communicatively connected to the master; and each layer of outbound controllers are respectively connected with the door lock switches corresponding to the outbound controllers.
Here, the respective floor door lock switches are connected in series, and as the series door lock switch, as shown in fig. 2, the door lock switches of the respective floor door lock devices are connected in series, and the respective floor door lock switches sequentially connected in series are used as the series door lock switch. As can be appreciated. The door lock switches connected in series in the elevator safety loop are normally closed switches, and when the elevator runs to the floor, the door lock switches corresponding to the floor are disconnected, so that the elevator safety loop is disconnected, and the elevator stops running.
Here, the outbound controllers provided on the respective floors may be communicatively connected to the master controller by a wired or wireless communication link, an optical fiber cable, or the like. Specifically, the master controller and the outbound controllers on each floor perform data communication through a CAN bus or RS 485.
The outbound controller is also connected with the door lock on the same floor. Specifically, the door lock switches of the door locks on the same floor of the outbound controller are connected, and information of the door lock switches can be collected.
Further, the door lock switches connected in series are the normally closed contacts of the door lock switches connected in series in sequence. It can be understood that when the elevator runs to a certain floor and the door is opened, the normally closed contact of the door lock switch of the floor is opened, namely the safety loop of the elevator is opened, and the running of the elevator up and down is stopped.
The head end of the series door lock switch is connected to the master controller, and the tail end of the series door lock switch can be connected to the signal acquisition end of the master controller; the series door lock switch and the master controller form a door lock loop for detecting the safety of a door lock in the elevator safety loop.
The second end of the normally closed contact of each door lock switch is connected to the outbound controller corresponding to each door lock switch, wherein the end, close to the master controller, of the normally closed contact of each door lock switch is the first end of the normally closed contact of each door lock switch. Here, the correspondence relationship in the "outbound controller corresponding to each door lock switch" means: the door lock switch arranged on the same floor and the outbound controller have a corresponding relation, and the address of the outbound controller on the same floor can be determined through the serial number of the door lock switch, or the address is opposite to the address of the outbound controller on the same floor. As an example, the number of the door lock switch on the same floor and the address of the outbound controller may be assigned to the same numerical value.
With continuing reference to fig. 3, fig. 3 shows the detection step of door lock disconnection in the door lock detection method based on the point-unified safety circuit, as shown in fig. 3, in the present embodiment, the door lock detection method based on the elevator safety circuit includes the detection step of door lock disconnection. The method specifically comprises the following steps:
and step 11, receiving the door lock information of each door lock switch.
In this embodiment, the master controller receives the door lock information of the door lock switch. The door lock information comprises door lock state information related to the connection or closing state of the door lock switch and door lock number information of the number of the floor where the door lock switch is located.
Here, the master controller receives the door lock information sent by each floor outbound controller through a CAN bus or an RS485 bus, and each outbound controller CAN also actively report the door lock information. The outbound controller of each floor collects the state information of the door lock switch of the same floor connected with the outbound controller. The door lock state information indicates information of an on state or an off state of the door lock switch.
The door lock number information can be information set according to the floor number of the door lock device; and the door lock number information is correspondingly set with the address information of the outbound controller on the same floor. Specifically, the number of the door lock device may be set according to the physical floor number. For example, the door lock devices of the floors of-3-18 are numbered 1-21, and the numerical values of 1-21 are assigned as the outbound controller addresses to the outbound controllers located on the floors of-3-18. In a specific application, the position of the door lock or the door lock switch can be determined through the door lock number information.
Before the door lock is disconnected and detected, the elevator can be stopped at a preset position, such as an overhauling position; therefore, the door lock state information acquired by the outbound controllers of each layer when the door lock switches are normal is in a connection state.
And step 12, determining the door lock switch with the disconnection fault according to the door lock state shown in the door lock state information and the door lock number size shown in the door lock number information.
In this embodiment, the master controller determines the failed door lock switch to be turned off according to the state of the door lock indicated in the door lock state information and the size of the door lock number in the door lock number information. In a specific implementation, the number of the door lock may be the number of the physical floor, and the door lock number at the bottommost floor is set to 1. When a door lock switch on a certain floor is disconnected, the door lock state information detected or collected by the outbound controllers on the corresponding floor and the floors below is in a disconnected state; and the door lock switch with the largest number is determined as the door lock switch with the disconnection fault. As shown in fig. 4, the step of door lock open fault confirmation in step 12 above may be broken down into multiple step implementation processes.
Further, the determining the door lock switch having the disconnection fault according to the door lock state indicated in the door lock state information and the size of the door lock number indicated in the door lock number information includes the following steps, as shown in fig. 4:
and step 121, determining the door lock switch with the disconnected door lock state as an abnormal disconnected door lock switch according to the door lock state shown in the door lock state information.
In this embodiment, when the master controller receives the state information of each layer of the door lock, the master controller may determine the door lock switch in the off state, and turn off the door lock switch in the off state as an abnormal off door lock switch. According to the relation that the door lock switches of all floors are connected in series, as long as the door lock switch of a certain floor before is disconnected, the states of the door lock switches collected by the outbound controllers of all floors after the floor are disconnected. Therefore, the abnormally-opened door lock switches in the opened state are not all the opened failed door lock switches.
And step 122, determining that the abnormal disconnection door lock switch with the minimum/large door lock number in the door lock number information is in disconnection fault.
In this embodiment, from the normally open door lock switches, the door lock switch with the largest serial number is determined to be an open fault, and the door lock corresponding to the door lock switch is determined to be a short-circuit fault door lock. For example, among floors from 1 to 40 in the physical floor, the door lock switch on the 10 th floor has an off failure, and the door lock state information detected by the outbound controllers on the 10 th floor and the following floors is in an off state. The door lock in the open state is the most numbered door lock switch at the 10 th layer, and the 10 th layer door lock switch is determined to be in the open fault. Further, after the 10 th floor door lock switch disconnection fault is cleared, disconnection fault detection of the door lock switches below the 10 th floor may be continued. It can be understood that if the control box (controller, driving device, etc.) of the elevator is installed at the bottommost floor of the floor, and the number of the door lock or door lock switch at the bottommost floor is 1, the door lock switch with the smallest number is determined as the open failure from the normally open door lock switches, and the door lock is the open failure door lock.
Further, the door lock detection method also comprises the step of sending the information of the disconnected failed door lock to the outbound controller of which the information is sent to the corresponding number. Here, the information for opening the faulty door lock includes a door lock opening fault flag and a number of the door lock. The outbound controller can display the serial number information or floor information of the disconnected faulty door lock, or adopt acousto-optic alarm to prompt maintenance personnel to quickly find the disconnected faulty door lock.
Further, the fault door lock switch can be determined to be turned off by the following scheme: the main controller sends the corresponding number of the initial floor in the abnormal disconnection door lock switch to each floor calling controller, each floor calling controller judges whether the number is consistent with the number of the floor where the number is located, and if the number is consistent, the door lock switch of the floor is determined to be a disconnection fault door lock switch. The floor call-out controller can display fault information or prompt maintenance personnel through sound and light alarm.
With continued reference to fig. 5, fig. 5 illustrates the steps of door lock short detection in an elevator safety loop based door lock detection method. As shown in fig. 5, the door lock short circuit detection step includes:
and step 21, moving the elevator upwards/downwards along the direction of the floor to stop the elevator at the floor where the door lock device to be detected is located.
In this embodiment, in the short circuit detection of the door lock device, it is possible to sequentially detect whether or not there is a short circuit failure in the door lock switches of the door lock devices on the respective floors from the direction of the maximum floor or the minimum floor. Specifically, the main controller controls the operation of the elevator, and the elevator is moved upwards from the bottommost floor along the floor direction, so that the elevator stops at the floor where the door lock switch to be detected is located, and the landing door of the floor is opened.
And step 22, receiving the door lock state information of the door lock switch.
The master controller receives the door lock state information of the door lock switch. The door lock state information is information related to the opening and closing state of the door lock.
And step 23, judging whether the state of the door lock switch is a closed state or not according to the door lock state information.
In this embodiment, the master controller obtains or receives the door lock state information of the door lock device of the floor where the elevator stops from the outbound controller in communication connection with the master controller, and determines whether the door lock switch of the door lock device is in a closed state or not according to the value of the door lock state information.
And 24, if the state of the door lock device is a closed state, determining that the door lock switch is in a short circuit fault.
In this embodiment, according to the judgment of the state of the door lock switch in step 23, if the door lock switch of the door lock device is closed, it may be determined that the door lock switch is in a short-circuit fault, and it is determined that the door lock is in a short-circuit fault. Based on the elevator safety circuit shown in fig. 2, when the elevator stops at a floor and opens the door, the door lock open/close state of the floor door lock device and the door lock open/close state of the following floor door lock device detected by each hall call controller should be in the off state. And if the floor call-out controller detects that the door lock switch of the door lock device is closed, the floor door lock switch can be determined to be in short circuit fault.
As an example, in the door lock short circuit detection, each outbound controller actively reports the door lock switch state information of each door lock device to the master controller in real time, and when the master controller detects that the information reported by the outbound controllers on the floor where the door is opened is inconsistent with the actually due information, the master controller actively reports the door lock short circuit fault number of the corresponding floor, and prompts maintenance personnel to maintain quickly.
Further, the master controller gives the floor position number of the floor of the door lock device in the closed state to all outbound controllers; after each outbound controller obtains the floor position number sent by the master controller, whether the received floor position number is consistent with the position of the floor where the controller is located is judged, if so, the corresponding floor outbound controller can display fault number prompt, and can also adopt sound and light form alarm prompt. The floor position number can be the physical floor number of the floor, and corresponds to the serial number of the door lock device and the address of the outbound controller. For example, the number of the floor position is 10, the number of the door lock device of the floor corresponds to the address of the outbound controller, that is, the number of the door lock device of the floor is 10, and the address of the outbound controller of the floor is 10.
It can be understood that after determining a certain layer of door lock short circuit fault, the elevator can continue to go up or down, and the short circuit fault detection of the next door lock is carried out until all door locks are detected.
Compared with the prior art, the door lock detection method based on the elevator safety loop has the following technical effects:
when a certain layer of door lock is disconnected, the door lock disconnection fault can be automatically identified, and meanwhile, the position of the fault door lock can be accurately positioned without manual successive arrangement of the door lock devices.
The door lock short circuit fault can be timely and accurately detected, and the floor where the short circuit fault is located can be accurately located.
An auxiliary contact switch is not required to be additionally arranged, and the outbound controller directly acquires the state information of the door lock; the loop door where the door lock is located is directly detected, a fault source is fed back truly, and misjudgment risks do not exist.
Therefore, the door lock detection method based on the safety loop can correctly detect the short circuit or disconnection fault of the door lock, and display the fault source through the outbound controller, thereby providing convenience for maintenance personnel.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
