Description

Elevator remote sensing and control system

The present invention relates to an elevator remote monitoring and control system, and in more detail, a new elevator remote monitoring and control capable of transmitting an elevator failure to a remote monitoring center and recovering the elevator failure according to a command from the remote monitoring center. It's about the system.

Conventionally, the idea to remotely monitor the failure of the elevator installed in the individual building has been proposed. The elevator remote monitoring device transmits the details of the failure to the remote monitoring center via a telephone line when a failure occurs during operation of the elevator, and the remote monitoring center recognizes the failure state of the elevator and sends maintenance personnel to the site. Sending has the advantage of being able to cope quickly. By the way, in the conventional remote monitoring system of the elevator, the signal transmission between the elevator and the remote monitoring center is mainly made in one direction, so that the signal of the abnormality of the elevator can be received at the remote monitoring center, but the abnormal recovery from the remote monitoring center It was not possible for the elevator to recover the abnormality by sending a command or control signal to the elevator. Therefore, the maintenance personnel to be dispatched to the site must always be waiting, so it was inevitable that a lot of cost and effort to maintain the elevator.

The present invention has been proposed to overcome the problems of the conventional elevator remote monitoring apparatus as described above. Specifically, the present invention is proposed by focusing on the fact that most frequently occurring elevator failures can be fully or partially recovered by electric and electronic remote operation, and the present invention detects the failure of elevators in a remote sensing center. It is an object of the present invention to provide an elevator remote monitoring and control system of a new structure that can be recovered completely or partially by remote control according to a fault.

As shown, the elevator unit 100 of the present invention is provided with a cage 110, the elevating drive mechanism 130 and the control panel 140 is installed on the upper end of the pit 112, which the cage 110 is elevated. . The control panel 140 is electrically connected to various buttons, switches, display units, and operation units of the elevator unit 100 to transmit and receive detection signals and control signals thereof. In addition, the cage 110 is provided with an indoor camera 142 and an outdoor camera 144. The indoor camera 142 transmits the video information on the passenger boarding or the operation button inside the elevator or the state of the crime or the like through the control panel 140 to the remote monitoring center 10 to be described later, specifically, the host computer. The outdoor camera 144 transmits the image information about the operating state of the elevator drive device or whether the external door 124 is open.

The control panel 140 is connected to the host computer 10 of the central remote monitoring center by a communication line, preferably a modem and a telephone line. The host computer 10 is provided with a memory unit 11 in which an error type code of an elevator is stored, and a monitor 12. Specifically, the error type of the elevator is mainly recoverable by electrical operation, so the remote recovery error code (E1), which can be recovered by remote control or by emergency action, and mainly recoverable by mechanical operation or for other reasons. Other error codes that require the operator's field work to solve are stored separately.

The error types and recovery methods belonging to the remote recovery error code (E1) are as follows.

(1) The door is opened and the mechanically closed door is detected as not electrically closed due to a failure of the outside door switch of the cage on which the floor is stopped. . After confirming that the door is closed by the outdoor camera 144 after the door closing command manually, after returning to the automatic mode if it is confirmed that there is no safety problem during the automatic operation of moving to the adjacent floor while observing the door state with the outdoor camera, Repair personnel dispatch

(2) The door is not closed due to a failure of the outside door switch on the floor other than the floor where the cage stopped, and the elevator is left open. After confirming that the passengers are rescued by moving to the adjacent adjacent floor, and then watching the hoistway with the outdoor camera 144, manually moving to the floor, checking whether there are any safety problems during the automatic operation, and returning to the automatic mode when it is determined to be safe, after which maintenance personnel are dispatched. restore

(3) Stopped with level mismatch above floor height data: Passenger check by voice or video communication in cage 110, switch to manual (low speed) mode when passengers are trapped and move to adjacent floor to rescue passengers, height Switch to measurement mode and return to automatic mode after floor height measurement.

(4) Stopped in the level mismatched state due to data deceleration at the time of deceleration: Checking whether passengers are trapped by voice or video communication in the cage 110, switching to manual (low speed) mode when checking passenger trapped, and moving to an adjacent floor. rescue. After changing the door into inoperable mode and correcting the deceleration time data, switch to the door operation mode if no abnormality is found.

(5) Door malfunction due to external button failure (stuck): If the button is pressed for more than a predetermined time, it is determined that the button is stuck, and the button is automatically operated after modifying it with a non-use button.

(6) Door inoperability due to defective safety shoe: stop operation of the door safety device and extend the automatic closing time sufficiently. Repair and recovery of maintenance personnel

(7) Detecting abnormal temperature in the machine room: Confirmation of passenger's presence by voice or video communication, and if there is a passenger, lift operation stop command and repair personnel recovery after the above-mentioned rescue operation.

(8) Abnormal operation frequency limit: After switching to manual mode, the upper limit of frequency of operation is extended, and after the maintenance personnel are dispatched, the wear level of each part is investigated and the abnormal wear parts are replaced after inspection.

(9) Input of crime occurrence signal: Police report and maintenance personnel dispatch

(10) Error in the system itself: reset the system

The error types described above are all error types that can be completely or partially recovered remotely by an electric control signal, and take a considerable weight in actual situations. In principle, all remaining errors should be sent to the rescue staff.

Referring to FIG. 2, the operation sequence of the remote monitoring and recovery of the system of the present invention will be described. First, when the elevator starts to operate (A), the remote monitoring system is activated (B), and if an error is found during operation (C), The remote monitoring center 10 is called to transmit an error code (D). Next, the error code is stored in the host computer of the remote monitoring center 10 and the audio image system is started. (E) Checking whether the passenger is trapped or not (F), if the passenger is trapped, stabilize the passenger by two-way communication. (G) Check the video system for door closure or other safety factors (H).

Next, it is determined whether the received error code is a remote recoverable error (I). If it is not a remote recoverable error, a recovery agent is dispatched to the field after the communication stops (J). If remote recovery is possible, start the remote recovery system (K). The first operation of the remote recovery system determines whether passenger rescue is necessary (L), and if passenger rescue is required, switches to the manual mode and moves to the adjacent floor to rescue the passenger (M). Subsequently, a remote recovery command for the generated error is issued to recover the error (N). The elevator is then restarted and terminated (O).

According to the present invention described above, unlike the conventional one-way remote monitoring or diagnostic apparatus, by providing a two-way communication and control system, a considerable recovery that is fully recoverable or at least partially emergency action by electro-electronic operation in the event of an elevator failure Remote errors can be recovered by remote control, and in particular, emergency passenger rescue operations can be performed quickly, which greatly improves the safety and convenience of the user while greatly reducing the effort for elevator management. It is possible to provide an elevator management system.
