Description

Elevator control system device {ELEVATOR CONTROLLING SYSTEM APPARATUS}

The present invention relates to an elevator, and in particular, by establishing a service tool control system network (hereinafter, referred to as a communication network) that connects elevators and elevator-related facilities to each other, such as maintenance or inspection of elevator cars and elevator-related facilities, etc. An elevator control system device for easily performing work in one or more places desired by at least one operator.

Elevators are longitudinal transportation means, ranging from small buildings to skyscrapers of tens of floors, depending on the purpose of the building. They are installed and operated according to the purpose of the building.

1 schematically shows the overall configuration of such an elevator system.

As shown, the elevator system consists of an elevator car 3 moving up and down along the hoistway 1 and a machine room 5 installed on the upper part of the hoistway 1 to control the movement of the elevator car 3. Although not specifically illustrated in the machine room 5, a hoist that moves the elevator car 3, a governor for detecting an abnormal speed of the elevator car 3, a power switchboard, and a movement of the elevator car 3 are controlled. A control panel (electric control system) is installed. Reference numeral 7 is a counterweight 9 is a rope.

On the other hand, the control panel is equipped with a microcomputer, the connection state made in the hoistway (1) and the machine room (5), the error inspection of the elevator car (3), the installation / maintenance of the elevator system and various input / output signal state, etc. And monitors the specifications of the building in which the elevator car 3 is installed and adjusts data applied to the elevator car 3 according to the mechanical system.

In other words, specification changes and adjustments for efficient control of elevators, and maintenance by inspection or various failures are performed through the control panel. This means that the operator must have access to the machine room 5 with the control panel for a series of actions. In order to check and repair the current elevator system, the operator works by connecting a service tool such as a laptop or console to the control panel in the machine room 5 by serial or parallel communication.

For this reason, the following problems are caused in the act of inspecting and repairing a conventional elevator system.

First, since the worker has to work only inside the machine room 5, it is impossible to know the various situations which take place outside the machine room 5 properly. That is, problems such as vibration, starting-up impact, abnormal noise, and the like, which are found only inside the elevator car 2, cannot be known, and an abnormality of the boarding indicator indicator, an abnormal problem in calling the hall, and a device which can be confirmed from the upper part of the elevator car 3 are known. It was not possible to adjust while checking the operation status of the field in real time.

In addition, when the elevator car 3 stopped, the operator had to go directly to the machine room 5 and check and repair. Therefore, if there are passengers inside the elevator car 3, the elevator should be operated normally as soon as possible to reassure the passengers, but the current maintenance process takes a lot of time to restart the elevator car (3). .

In addition, when the elevator car 3 is stopped at present, the level of the current situation is recognized by talking to the manager through an interphone installed inside the elevator car 3. However, the manager is not able to know the failure check state of the elevator car 3 in real time, and does not provide accurate information to the passengers. As a result, passengers do not hide their anxiety, and if the elevator suddenly restarts, passengers may be surprised or injured.

Therefore, an object of the present invention is to solve the above problems, to allow the at least one or more operators to perform multiple adjustments, maintenance and inspection activities for the operation of the elevator at any place connected to the elevator and the elevator-related equipment will be.

Another object of the present invention is to enable the operator to visually check the operation, such as adjustment, maintenance and inspection of the elevator directly at the location.

Still another object of the present invention is to remotely control an elevator car stopped by a failure so as to restart the elevator car in the shortest time.

Still another object of the present invention is to enable passengers inside an elevator car to accurately recognize in real time the failure check state of the elevator.

According to a feature of the present invention for achieving the above object, a connection connector connected to the control panel of the machine room through a communication line and installed in the interior and exterior of the elevator car, and the platform, respectively; And a service tool for connecting to the connection connector, wherein the service tool is connected to a connection connector installed in at least one of the inside and the outside of the elevator car and a platform for an elevator car according to a remote control with the control panel. Characterized in that it can perform the inspection and repair acts on the elevator-related equipment.

In addition, when the elevator car is stopped, the service tool may perform a reset operation on an error held in the control main board of the control panel while connected to the connection connector.

In addition, when the elevator car is stopped by the safety switch operation, the service tool can check the position of the safety switch, bypass the safety switch (By-Pass) and drive the elevator car at a speed lower than the normal speed. have.

In this case, a step-by-step authentication procedure is performed through the service tool.

In addition, the present invention, when the service tool is connected to the connecting connector for adjustment, inspection and maintenance of the elevator system, the service tool notifies the progress information inside the elevator car.

According to the elevator control system device of the present invention configured as described above provides the following effects.

 First, the inspection, adjustment, and repair operations of the elevator are not limited to the conventional machine room, and the operator can perform various tasks while checking the state of the elevator car directly at the site where the work is to be performed, thus enabling accurate and rapid measures.

In addition, even if the elevator car is stopped due to a malfunction, the operator can use the service tool to reset the failure error at the nearest location or bypass the operated safety switch to restart the elevator car in the shortest time. Can promote passenger safety.

Hereinafter, preferred embodiments of an elevator multiple control apparatus and method according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram of an elevator multiple control apparatus according to a preferred embodiment of the present invention.

As shown, the present invention extends the communication network established in the existing elevator system to build a communication network from the control panel of the machine room to the interior and exterior of the elevator car, platform. Specifically, the control panel 100, the internal operation panel 112 and the LCD 114 installed inside the elevator car 110, the platform operation panel (lift button) 120 is installed on the platform of each floor, and the elevator car 110 Connection box 130 installed on the upper portion of the interconnection network configuration. The connection box 130 is a configuration installed to connect the communication network. Of course, if the configuration that can be directly connected to the communication line directly on top of the elevator car 110, the configuration of the connection box 130 is not necessary.

The connection box 130 and the control panel 100, the internal control panel 112, and the platform operating panel 120 described above are service tools (laptop or console equipment, etc.) capable of maintenance, inspection, adjustment, and specification change (200). Connection connector 150 should be further configured. The connection connector 150 may be formed with one or more terminals. That is, connection terminals are formed to correspond to the types of cables connected to the various terminals formed in the service tool 200, so that they are not limited to a specific cable. The connection connector 150 may be protected by a mechanical locking device to be disconnected from the outside.

The control panel 100 performs an operation according to a remote control request of the service tool 200. That is, when the service tool 200 connected to the control panel 100 and the communication network generates a request for restarting the elevator or starting the elevator car in a stopped state at a predetermined speed or less, the control panel performs a reset operation or Performs BY-PASS function that bypasses the active safety switch. Accordingly, the control panel 100 is equipped with a hardware device having a specific function for performing the bypass function so that the above-described operation can be performed, and the corresponding function should be programmed. Therefore, the control panel 100 should be provided with a program and an apparatus for performing the above functions. Of course, the control panel 100 stores the driving information or failure information of the elevator car 110, and when a request is generated from the service tool 200, the control panel 100 is various information to the service tool 200. Will be provided.

Meanwhile, the service tool 200 displays progress or other information currently being performed by the operator on the LCD 114. This indicates the fact that maintenance work is being performed to minimize the impatience for passengers inside the elevator car 110 stopped by a failure or information that the passengers can prepare in advance when the elevator car 110 is restarted.

3 and 4 are exemplary diagrams in which a communication network for the elevator control system device of the present invention is constructed. Of these drawings, FIG. 3 is an example in which a communication network is constructed in a hoistway and a machine room, and FIG. 4 is an example in which a communication network is constructed in an elevator car.

3, in the control panel 100 of the machine room, a communication line is installed along the hoistway A, and the communication line 300 is connected to various devices installed in the hoist of each floor of the building. That is, the hole call button, the vertical display device, the horizontal display device, and the like can be referred to. These devices are formed with a connection connector 150 for connecting the service tool 200. In this case, an interface means 310 such as a coupling bracket may be used between the communication lines 300 to extend the communication lines 300. In the drawing, the interface means 310 is fixedly installed on the wall surface of the hoistway A.

Referring to FIG. 4, a connection box 130 is installed to connect the service tool 200 from the upper part of the elevator car 110 to perform inspection, adjustment, and maintenance. The connection connector 150 is also formed in the connection box 130.

 Referring to the operation of the elevator control system apparatus according to an embodiment of the present invention configured as described above are as follows. At this time, the description will be made in two ways according to the control target.

Specification change and adjustment control

This is the case when it is necessary to adjust the data values necessary to start the elevator car according to the specification change and mechanical system according to the information of the building in which the elevator is installed. In this case, in the related art, the operator necessarily connected the service tool 200 to the control panel only in the machine room to adjust or change data values.

However, in this embodiment, the operator can work by connecting the service tool 200 directly to the connection connector at a location where the operator is easy to work, such as the interior and exterior of the elevator car 110, the platform without access to the machine room. do.

Inspection and Repair

Inspection related to the elevator is not limited to any particular site.

In connection with the operation of the elevator car 110, an inspection factor occurs in the interior or the upper part of the elevator car 110, and also in the platform.

That is, it is preferable to check the vibration of the elevator car 110, the impact at the start, the noise, etc. in the interior of the elevator car 110. In addition, a variety of devices are installed on the upper portion of the elevator car 110, it is preferable to check the operating state of these devices directly from the upper portion of the car (110). Also, it is advisable to check the platform at the platform because problems such as an indicator failure or a hall call malfunction may occur.

In the past, these inspections were performed by the operator going to the machine room and connecting the service tool 200 to the control panel 100. However, as described above, such a check has a problem that the operator cannot check while checking in real time.

However, according to the present embodiment, the operator may check and inspect while directly checking the part to be checked. That is, the operator checks the service tool 200 by connecting the service tool 200 to each of the connection connectors 150 installed in the interior, the upper part of the elevator car 100, and the platform according to the object to be inspected, and performs the inspection through communication with the control panel 100. You can check the items yourself.

This can be more clearly seen with reference to the illustrated drawings. For example, as shown in FIG. 5, an operator connects the service tool 200 to the control panel 100 in the machine room as in the related art. The operator uses the service tool 200 and the control panel 100 by connecting the cables.

Another example is when the operator makes a control action on the platform. This is shown in Figure 6, the operator connects the service tool 200 with a cable to the connection connector 150 formed on the platform operating panel 120 of the platform.

As another example, a worker may use the service tool 200 inside the elevator car 110. This may be done by connecting the service tool 200 to the connection connector 150 formed in the internal control panel 112 inside the car 110 as shown in FIG. 7. In addition, as shown in FIG. 4, the service tool 200 is connected to the connection connector 150 of the connection box 130 on the upper portion of the elevator car 110 to directly service the upper portion of the elevator car 110. Tool 200 can be used.

As such, since the service tool 200 connected to the connection connector 150 is connected to the control panel 100 through a communication network, the service tool 200 has an effect of remotely controlling the control panel 100 at a long distance.

Next, an example in which the elevator car 110 is operated again by using the service tool 200 when the elevator car 110 is stopped due to a failure is described.

When the elevator car 110 is stopped during operation, the elevator car must be driven again to rescue passengers trapped inside in the shortest time. The following two methods are proposed.

Firstly, the elevator car 110 is reset.

When the elevator car 110 stops at a predetermined position of the hoistway A due to a failure during operation, the control panel 100 detects this and notifies the manager or the worker of the failure state through various channels.

The worker has to drive the elevator car 100 again in the shortest time. Therefore, the worker connects the service tool 200 to the connection connector 150 in the closest place to the place where he is located. This example will be referred to FIG. 6. That is, the operator should check the cause when a failure occurs, and if the service tool 200 is connected to the connection connector 150 of the platform operating panel 120 on the first floor or the reference floor without performing a series of user authentication, The control panel 100 transmits current failure occurrence cause information to the service tool 200 so that an operator can check. The cause of the failure at this time is possible because the control panel 100 is recognized through the communication network.

Therefore, when the operator checks the cause of the failure, the service tool 200 is remotely connected to the control panel 100 without holding and restoring the main power of the elevator car 110 to be held on the control main board of the control panel 100 ( The elevator can be restarted by performing a reset operation on the held error. At this time, the information on the cause of the failure is the state that the control panel 100 temporarily stored.

The reason why the elevator can be restarted by only a reset operation is that more than 70% of elevator failures can be solved by simply shutting off and restoring the main power.

In this way, the operator can quickly determine the cause of the failure, as well as enable the elevator to run again with a reset operation by remote operation.

Second, the elevator car 110 is stopped at a certain speed due to a failure.

During the operation of the elevator car 110, the operation of the elevator car 110 may be stopped due to a breakdown or a safety accident. At this time, most of the safety switch associated with the driving of the elevator car 110 is operated so that the elevator car 110 is stopped.

Therefore, the worker connects the service tool 200 to the connection connector 150 located closest to him. The connected service tool 200 may remotely control the control panel 100, whereby the control panel 100 may know in which position the safety switch currently operated is installed. This information is transmitted to the service tool 200, so that the operator can determine the position of the operated safety switch. Therefore, the operator performs a function of bypassing the currently operated safety switch by remotely controlling the control panel 100, and allows the elevator car 110 to run only below a certain speed. At this time, the operator must perform step-by-step authentication procedure for user authentication or function performance. This is because there is a close relationship with the passenger safety in the elevator car (110). Of course, when the safety switch is operated, it is obvious that the elevator system 110 has to be set in advance in the elevator system so that the elevator car 110 operates only at a predetermined speed or less through the above-described authentication procedure. Here, the constant speed refers to a speed slower than the speed at which the elevator car 110 normally operates, and the value is determined by an initial setting value such as 50%, 30%, 10%, etc., compared to the normal speed. Can be.

As such, even when the elevator car 110 is stopped, the worker may temporarily drive the elevator car 110 below a predetermined speed even before the elevator car 110 is normally operated using the service tool 200. Passengers inside the car can be pulled out quickly.

On the other hand, the service tool 200 notifies the passengers step by step the whole process from the time when the service tool 200 is connected to the connecting connector 150 due to the failure of the elevator car 110 to check or repair the failure can do. This action may cause a series of programmed data to be notified via an output means such as LCD 114 or simply connect the service tool 200 to the connection connector 150 or the connected state of the service tool 200. The control panel 100 may recognize the control panel 100 to display related information on the LCD 114. When the breakdown is completed and the elevator car 110 restarts, the passengers are provided with a function of notifying the passengers that the repair is completed and the elevator car 110 is restarted, so that when the elevator car 110 is suddenly restarted. Allow passengers to prepare for impacts, etc.

As described above, it can be seen that the present invention enables the operator to quickly perform an operation such as checking, adjusting, and repairing the elevator car 110 and related facilities, even in an elevator car and a boarding station. In addition, the elevator car can be restarted in the shortest time by using the reset operation in case of failure of the elevator car or the bypass function of the circuit.

On the other hand, in the embodiment of the present invention has been described that one worker performs the inspection, adjustment and maintenance of the elevator system, but a plurality of workers can work in multiple by connecting the service tool to each connection connector have.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be apparent that modifications, variations and equivalents of other embodiments are possible. Therefore, the true scope of the present invention should be determined by the technical idea of the appended claims.
