First, an elevator monitoring system according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5.

As shown in Figure 1, the elevator monitoring system 100 according to the present invention includes a control unit (110_1 to 110_n) and the failure information processing unit 120. In addition, the elevator monitoring system 100 further includes a remote monitoring server 130 and the manager interface 140.

Each control unit 110_1 to 110_n is connected to at least one elevator 200_1 to 200_n to receive the operation information of the elevator. Here, the driving information includes elevator identification information, opening / closing information of the car door, car stop floor information, speed, communication state with the controller, reverse driving, brake state, emergency stop, and the like.

The failure information processing unit 120 stores the operation information transmitted from each of the controllers 110_1 to 110_n, analyzes the failure status and the failure type of the elevator from the operation information, stores the failure type and the operation information related thereto, and the manager. Provides information on the type of fault and its associated operation upon request. The failure information processing unit 120 having such a function includes a failure type storage unit 121, a driving information storage unit 122, a processor 123, and a failure information storage unit 124 as shown in FIG. 2. . The failure type storage unit 121, the driving information storage unit 122, and the failure information storage unit 124 may be implemented as one memory M.

The failure type storage unit 121 stores an elevator failure type and a corresponding failure code. Table 1 below shows an example of an elevator failure type and a corresponding trouble code (TCD: Trouble Code) stored in the elevator failure type storage unit 121.

Fault code Elevator failure type  TCD 001  Communication error with the control unit  TCD 010  Reverse run detection  TCD 011  Breakoff breakdown  TCD 100  Door Open Lock Detection  TCD 101  Door Close Lock Detection  TCD 110  Emergency stop detection

The driving information storage unit 122 stores driving information transmitted from the controllers 110_1 to 110_n and preferably has a size capable of storing 128 elevator event information. The elevator event information is information about a change in the elevator running state. For example, there may be a hall call, an elevator movement, a door off, a car call, or the like. The driving information storage unit 122 sequentially stores the elevator event information transmitted from the controllers 110_1 to 110_n, and the elevator event information recorded last is output first, and the elevator event information recorded first is output last. To store the elevator operation information and event information in a stack structure.

The processor 123 analyzes whether information corresponding to the elevator failure type information stored in the failure type storage unit 121 is included in the elevator operation information transmitted from the elevator controllers 110_1 to 110_n, and there is an elevator failure occurrence. If it is determined that the failure of the elevator has occurred, and outputs a failure code corresponding to the elevator failure.

The failure information storage unit 124 stores a failure code output from the processor 123 and a plurality of elevator event information extracted from the driving information storage unit 122 corresponding thereto. For example, when a predetermined number, for example, 100 event information is extracted from the event information stored in the driving information storage 122 before the corresponding failure occurs in response to one failure code, the failure information storage unit 124 may fail. Save code and extracted 100 event information. As described above, one error information group including one fault code and 100 event information is stored in the fault information storage unit 124 in the form as shown in FIG. 4. A plurality of fault information groups having the same fault code but different event information may be stored in the fault information storage unit 124. In this manner, a predetermined number of fault information groups having the same fault code are stored in the fault information storage unit 124. In order to store the latest fault information group, it is advisable to delete the fault information groups in the order of the first stored information. It may be.

2, the remote monitoring server 130 is responsible for transmitting information between the failure information processing unit 120, the manager interface unit 140, and the maintenance center 300.

The manager interface 140 provides the manager with the fault code and elevator related event information transmitted from the fault information processor 120 through the remote monitoring server 130, and requests additional operation information and maintenance information related to the fault code from the manager. It receives the input and transmits it to the remote monitoring server 130. Meanwhile, the manager interface 140 may selectively provide a manager with a plurality of fault codes and elevator related event information transmitted from the fault information processor 120 through the remote monitoring server 130. The additional operation information request and maintenance information related to the failure code are transmitted to the failure information processing unit 120 and the maintenance center 300 through the remote monitoring server 130, respectively. The maintenance information includes the cause of the failure and the countermeasure. An example of commands input to the manager interface unit 140 is illustrated in FIG. 5.

Hereinafter, an elevator monitoring method according to an embodiment of the present invention will be described in more detail.

Referring to FIG. 6, each of the controllers 110_1 to 110_n collects driving information of at least one elevator connected thereto (S100).

The processor 123 of the failure information processing unit 120 has information corresponding to the failure type information in the elevator operation information transmitted from the controllers 110_1 to 110_n based on the failure type information stored in the failure type storage unit 121. By comparing the presence (S110), it is determined whether the elevator failure occurs (S120). At this time, it is determined whether a failure occurs according to whether the failure type stored in the failure type storage unit 121 is included in the collected elevator operation information.

If it is determined that the elevator is operating normally in step S120, the failure information processing unit 120 stores the driving information in the driving information storage unit 123 (S130).

On the other hand, if it is determined that a failure has occurred in the elevator in step S120, the processor 123 outputs a failure code corresponding to the failure type (S140). For example, when it is determined that the breakoff failure information is included in the driving information collected by the controller 110_6, the processor 123 may respond to the breakoff failure based on the stored information of the failure type storage unit 121. Outputs the TCD 011 fault code. In addition, the processor 123 extracts a predetermined number of event information stored in the driving information storage 122, for example, 100 recent event information (S150), and a fault information group including a fault code and extracted event information. The fault information storage unit 124 is stored (S160). The processor 120 transmits the failure information group to the remote monitoring server 130 (S170).

The remote monitoring server 130 transmits the received failure information group to the manager interface unit 140 (S180), and the manager interface unit 140 provides the administrator with the failure information group received from the remote monitoring server 130. (S190). This provision is in the form of a display.

The processor 123 of the failure information processing unit 120 determines whether there is a request for additional information from the manager interface unit 140 (S200). The additional information includes a failure information group (hereinafter, referred to as a similar failure information group) and a previous failure information group having the same failure code as the failure code (hereinafter referred to as current failure code) corresponding to the currently generated failure type. .

If it is determined in step S200 that there is a request for additional information, the processor 123 analyzes the requested additional information (S210). For example, when there is a request for a similar failure information group, it is searched whether a failure information group having the same failure code as the current failure code exists among the failure information groups stored in the failure information storage unit 124 and, if present, is less than or equal to a predetermined number. Similar failure information of the group is transmitted to the remote monitoring server (130) (S220). In addition, when there is a request for a previous failure information group, the failure information storage unit 124 retrieves a predetermined number of recently stored failure information groups and transmits them to the remote monitoring server 130.

The manager interface 140 receives additional information from the remote monitoring server 130 and provides the manager with the additional information (S230).

Thereafter, the manager interface 140 transmits maintenance information input from the manager to the maintenance center 300 through the remote monitoring server 130 (S240).

In this case, the failure codes and failure types shown in Table 1 are stored in the first failure type storage unit, and whether or not a failure occurs is primarily determined in the controllers 110_1 to 110_n. The failure occurrence determination method is made in the same manner as the determination method in the processor 123 of the failure information processing unit 120, and a detailed description thereof will be omitted.

When the controllers 110_1 to 110_n primarily determine whether a failure occurs, the failure information processing unit 120 secondly determines whether a failure occurs. To this end, the second failure type storage unit 121 in the failure information processing unit 120 stores additional failure types and corresponding additional failure codes as shown in Table 2.

As described above, according to another exemplary embodiment of the present invention, the controllers 110_1 to 110_n and the failure information processing unit 120 determine whether primary and secondary failures occur, respectively, thereby reducing a failure determination error.

In addition, in another embodiment of the present invention, the failure type storage unit is not provided in the controllers 110_1 to 110_n, and the failure types of the tables 1 and 2 and the corresponding failure codes are all the failure information processing unit 120. It may be stored in the failure type storage unit 121 therein. In this case, only one failure type storage unit 121 may determine whether a failure occurs based on more various types of failures.

In addition, according to another embodiment of the present invention, the failure information processing unit 120 may simultaneously provide additional information to the manager along with the current failure code and event information group. The additional information may be an additional event information group related to the same code and / or a previous nose length code and at least one event information group corresponding thereto. In this case, unlike the above-described embodiment of the present invention, additional information may be provided to the manager without receiving a request for additional driving information from the manager.
