Example 1
Fig. 1 is a flowchart of an elevator maintenance method according to a first embodiment of the present invention, where the present embodiment is applicable to a case where a remote monitoring maintenance state is exited with a delay according to a state of operation of an elevator, the method may be performed by an elevator maintenance device, the elevator maintenance device may be implemented in hardware and/or software, the elevator maintenance device may be configured in a remote monitoring terminal, the remote monitoring terminal is a terminal portion of a remote monitoring platform, and the remote monitoring terminal is disposed at an elevator.
The remote monitoring terminal belongs to the Internet of things, the functions of main board data acquisition and signal receiving and transmitting are added, the function is realized by adding a flow card of the Internet of things, the remote monitoring platform can remotely monitor the elevator, and faults and errors in the operation process of the elevator can be timely recorded.
Some remote monitoring terminals have the function of shielding fault report during elevator overhaul, and the implementation modes are as follows:
firstly, a shielding button is configured on a remote monitoring terminal, a maintenance person presses the shielding button on the remote monitoring terminal when preparing to overhaul the elevator, and presses the shielding button on the remote monitoring terminal when finishing overhaul the elevator.
Secondly, the remote monitoring terminal obtains an overhaul signal of the elevator as a basis for entering or exiting a shielding fault transmitting mechanism, and in fact, the elevator is not always in an overhaul state in the overhaul process, and the elevator needs to be normally operated after the elevator overhaul is completed, so that whether the fault is solved or not is confirmed, if the fault still exists, the elevator enters the overhaul again, and the operation is repeated until the fault is not repeated. By adopting the mode, the fault generated in the normal operation in the overhaul process can be transmitted to the remote monitoring platform, and the reliability of the fault transmission can not be ensured.
Therefore, the embodiment provides a more accurate method for shielding fault report during elevator overhaul according to operation guidance of maintenance personnel and operation habits of overhaul elevators of long-term collection maintenance personnel.
As shown in fig. 1, the method includes:
and 101, monitoring various overhaul signals generated by the elevator.
In a specific implementation, the elevator types and functions are different, such as passenger, freight, sightseeing, etc., and thus the elevator components are also different.
In one example, the components of the elevator include a hoisting machine, a control cabinet, a speed limiter, a door opener, a car frame, a car door, a counterweight guide rail, a car guide rail, a guide rail bracket, a travelling cable, a counterweight, a compensation chain (cable), a landing door, a guide for the compensation chain (cable), and a buffer.
In some types of elevators, the hoisting machine, the control cabinet, the speed limiter, the travelling cable, and other components may be omitted, and this embodiment is not limited thereto.
Some parts in the elevator have fault detection capability, when the elevator fails, an overhaul signal is actively generated and uploaded to the remote monitoring terminal, some parts do not have fault detection capability, various sensors can be configured to collect the operation data of the parts, the operation data of the parts are analyzed to detect whether the parts fail, and when the parts fail, a fault signal is generated and uploaded to the remote monitoring terminal.
Of course, in addition to self-detecting faults, the fault signal may be triggered manually by passengers or property personnel, which is not limited in this embodiment.
In a normal mode, if the remote monitoring terminal collects any fault signal generated by the elevator, the fault signal is reported to the server, a customer service system is deployed at the server, customer service personnel log in the customer service system, and the customer service system can analyze the fault signal when receiving the fault signal, so that the failed elevator and a failed component thereof are determined, and an maintainer is automatically ordered or notified to go to the site for rescue and overhaul of the elevator.
When the elevator fails, the elevator can continue sliding until passengers are sent out according to the failed component, or directly stop running, wait for rescue, and shield the elevator calling request of a user.
In addition, the elevators are usually maintained regularly (such as 1 month, 2 months, etc.), which is the preventive maintenance before the elevators fail, and the customer service system automatically orders or the customer service personnel is informed to the maintenance personnel to go to the site to examine the elevators.
The maintenance personnel arrive at the elevator site, press the maintenance button of elevator and trigger the maintenance signal to place the rail outside the gate of some hall of waiting for an elevator and warn, at this moment, the elevator gets into the maintenance mode. In practical application, monitor the terminal control elevator and produce various signals remotely, including monitoring whether the elevator produces the maintenance signal, arbitrary maintenance signal all is used for showing the elevator and starts the maintenance mode, overhauls the position of elevator, for example, overhauls the maintenance signal that overhauls the sedan-chair top, overhauls the maintenance signal in the sedan-chair, overhauls the maintenance signal that overhauls the computer lab, overhauls the maintenance signal that overhauls the pit.
Step 102, if any maintenance signal is acquired, a remote monitoring maintenance state is started for the elevator.
In this embodiment, a remote monitoring maintenance state may be newly added to the elevator, where the remote monitoring maintenance state is a state of whether to shield the maintenance signal in the dimension opposite to the normal mode, and not shield various maintenance signals in the normal mode, and shield various maintenance signals in the remote monitoring maintenance state, that is, if any fault signal generated by the elevator is collected outside the remote monitoring maintenance state, the fault signal is reported to the service end. If the elevator is in a normal running state and the maintenance signal is received for the first time, a remote monitoring maintenance state can be started for the elevator, namely, a flag bit representing the remote monitoring maintenance state is written in a system of the elevator.
Step 103, if any fault signal generated by the elevator is collected in the remote monitoring maintenance state, the fault signal is shielded.
When receiving any fault signal generated by the elevator, the remote monitoring terminal can detect whether the elevator is in a remote monitoring maintenance state, namely, whether a zone bit representing the remote monitoring maintenance state exists in a system of the elevator or not, and if the elevator is in the remote monitoring maintenance state, namely, the zone bit representing the remote monitoring maintenance state exists in the system of the elevator, the fault signal is shielded.
Further, the step of screening the fault signal may mean that the fault signal is prohibited from being reported to the server, and then the remote monitoring terminal may store the fault signal permanently and mark the fault signal as invalid, wait for statistics and analysis of the overhaul condition, or the remote monitoring terminal may discard (delete) the fault signal directly, which is not limited in this embodiment.
104, if the elevator exits the overhaul mode, the elevator exits the remote monitoring overhaul state according to the running state of the elevator.
In the process of maintaining the elevator by the maintenance personnel, the maintenance personnel can actively control the elevator to exit the maintenance mode, test the elevator or finish maintenance of the elevator, and at the moment, passengers can normally take the elevator.
Then, for these possible situations, the present embodiment exits the remote monitoring service state for the elevator according to the state of operation of the elevator.
In one embodiment of the present invention, step 104 may include the steps of:
step 1041, timing a first time period that can cover the test elevator.
Step 1042, if the timing reaches the first time, the elevator is exited from the remote monitoring maintenance state.
In the process of overhauling the elevator, maintenance personnel can test the elevator by exiting the overhauling mode and recovering to the normal mode, and the elevator does not represent that overhauling operation is finished after exiting the overhauling mode, so that the elevator still needs to maintain a remote monitoring overhauling state for a period of time (namely, a first time length) and maintain a shielding fault signal after exiting the overhauling mode, thereby maintaining a shielding fault transmitting state.
The remote monitoring maintenance state is automatically released after a certain time (namely, the first time length) is delayed, so that the situation that the remote monitoring terminal is always in a shielding fault transmitting state to cause fault to generate error shielding fault signals in normal use can be prevented, and the first time length of the remote monitoring maintenance state is delayed to be released, usually according to the estimated longest time length of maintenance personnel in normal operation of the test elevator, such as 2 hours, so that the maintenance personnel can be covered to test the elevator.
In one embodiment of the present invention, step 104 may further comprise the steps of:
step 1043, monitoring a first operation signal for controlling the elevator to stop running when the elevator is stationary during the first time period.
Step 1044, if any one of the maintenance signals or the first operation signal is collected in the remote monitoring maintenance state, the timing of the first time is canceled.
In practical application, maintenance personnel may find that the elevator still has a small problem when testing the elevator, and generally is used to control the elevator to stop, and the maintenance operation is continued after the emergency stop button is pressed under the static state of the elevator, and the maintenance button is not pressed again at the moment generally, so that the logic of pressing the emergency stop button during the static state is that the hardware safety loop of the elevator is triggered and the safety device is not triggered.
In this embodiment, during the countdown (i.e. counting the first time period), if any one of the maintenance signals of the elevator is triggered again or the emergency stop button is pressed when the elevator is stationary (i.e. triggering the first operation signal for controlling the elevator to stop running), the countdown will be cancelled (i.e. cancelling the first time period), and the elevator will wait again to exit the maintenance mode again, and then the countdown (i.e. counting the first time period) is performed.
In another embodiment of the present invention, step 104 may further include the steps of:
step 1045, counting the first times of normal operation of the elevator in the process of timing the first duration.
Step 1046, if the first number is greater than or equal to the first threshold and less than the second threshold, shortening the first duration.
During the countdown (i.e., counting the first time period), the first number of normal elevator operations may be counted.
In the normal operation process, the elevator responds to the elevator calling request sent by the passenger through the control panel or the client of the elevator waiting hall, controls the elevator car to slide to the floor where the passenger is located, opens the car door, closes the elevator car after the passenger enters the elevator car, controls the elevator car to slide to the destination floor, opens the car door, closes the elevator car after the passenger enters the elevator car, and during the period, each part of the elevator does not fail.
The maintenance personnel can leave after finishing the maintenance operation at least once in the elevator operation test, so that whether the elevator operates normally or not can be monitored, and the first times of normal operation of the elevator can be accumulated.
If the first number of times is greater than or equal to a first threshold value (e.g., 1) and less than a second threshold value (e.g., 10), it indicates that the elevator has a certain probability of completing maintenance, and the first time period can be shortened.
In general, the shortened proportion may exceed a preset proportion threshold (e.g., 1/2), i.e., the duration of the countdown (i.e., the first time period of the timer) is greatly shortened, e.g., from 2 hours to 45 minutes, so as to slow down or avoid the failure of the passenger during the elevator using process, which is caused by the occurrence of the failure and the shielded failure signal.
In another embodiment of the present invention, after step 1046, step 104 may further include the steps of:
step 1047, continuously counting the second times of normal operation of the elevator on the basis of the first times in the process of timing the first time.
Step 1048, if the second number of times is greater than or equal to the second threshold value, exiting the remote monitoring maintenance state for the elevator.
In the process of countdown (namely, counting the first time duration), whether the elevator runs normally or not can be continuously monitored, and the times of normal running of the elevator are continuously accumulated on the basis of the first times, so that the second times of normal running of the elevator are counted.
According to industry experience, if the second time is greater than or equal to a second threshold (e.g. 10), the elevator is basically cleared of faults, overhauled and delivered for passengers, and at the moment, the elevator can be out of a remote monitoring overhauling state, and the shielding fault transmitting state is released.
In another embodiment of the present invention, after step 1046, step 104 may further include the steps of:
step 1049, in the process of timing the first duration, if any maintenance signal is collected in the remote monitoring maintenance state, timing the second duration.
In the process of countdown (namely, the first time after the time is shortened), any fault signal which causes the elevator to stop running is collected in the remote monitoring maintenance state, and then the second time can be counted.
Typically, the second time period is much less than the first time period, e.g., the first time period is 45 minutes, and the second time period is 5 minutes.
Step 1050, during the timing of the second time period, monitoring a second operating signal of the non-passenger controlled elevator.
Step 1051, if the timing reaches the second duration and the second operation signal is not collected, the remote monitoring maintenance state is exited for the elevator.
In the process of timing the second duration, whether the elevator generates a second operation signal of the non-passenger control elevator is monitored, and the manner of controlling the elevator by the passenger mainly comprises the operation of the control panel in the lobby and the operation of the control panel in the car, so that the second operation signal of the non-passenger control elevator can refer to signals except the control panel of the lobby and the control panel in the car, for example, signals except the signal triggered by the pressing of an external call button by the passenger, the signal triggered by the pressing of an intercom button by the passenger, and the like.
If maintenance personnel find a fault in the process of testing the elevator, the emergency stop button, the maintenance button, the hall door lock and the power switch are generally operated, if a second operation signal is continuously not generated in the process of timing a second time period, the fault possibly belongs to the generation of the elevator using process in the running process, the remote monitoring maintenance state is immediately exited, the fault signal is normally responded, and the fault signal is reported to a service end to prompt the elevator to fail and wait for maintenance.
In the embodiment, the remote monitoring terminal monitors various overhaul signals generated by the elevator, and any overhaul signal is used for indicating an elevator to start an overhaul mode for overhaul; if any maintenance signal is acquired, starting a remote monitoring maintenance state for the elevator; if any fault signal generated by the elevator is collected in the remote monitoring maintenance state, the fault signal is shielded; if the elevator exits the overhaul mode, the elevator exits the remote monitoring overhaul state according to the running state of the elevator. According to the embodiment, the overhaul signal and the elevator operation state are used as conditions for controlling the start and the exit of the remote monitoring overhaul state, the automatic control of the remote monitoring overhaul state is realized, a maintenance person is not required to manually control the remote monitoring overhaul state, the operation is simple and convenient, the elevator operation state is analyzed according to the elevator overhaul experience, the remote monitoring overhaul state is timely delayed and exited, the fault signal can be shielded in the elevator testing process, the accuracy of the maintenance rescue list under the customer service system is ensured, the manual further and on-site confirmation is avoided, the working difficulty of the customer service person is reduced, the influence on the investigation and evaluation of the overhaul capacity of the maintenance person is avoided, and the normal use of the elevator by passengers is ensured.
