Description

Elevator monitoring system and elevator monitoring method

Technical Field

The invention relates to the field of elevators, in particular to an elevator monitoring system and an elevator monitoring method.

Background

The existing elevator is usually equipped with an elevator remote monitoring system, a data acquisition device on an elevator site is used for acquiring relevant data of the elevator, the acquired relevant data of the elevator is uploaded to a remote monitoring center far away from the elevator site in a wired or wireless mode through certain network equipment, and the remote monitoring center analyzes and processes the received elevator data to realize functions of omnibearing monitoring of the elevator, maintenance of the elevator according to needs, failure prediction and the like. For example, chinese patent application CN104176613B proposes an abnormality diagnosis system for a passenger conveyor, which includes a sensor terminal capable of wireless communication provided at a predetermined position of the passenger conveyor, a data collection device for collecting data detected by the sensor terminal, and a remote monitoring device connected to the data collection device via a communication line and acquiring measurement data of the sensor terminal from the data collection device, wherein the remote monitoring device stores the measurement data, performs frequency analysis on the measurement data, and determines a change in state of the passenger conveyor based on the analysis result.

In order to monitor the elevator in all directions and achieve as many functions as possible, elevator data of a great number of types need to be collected, and the collection frequency is very high, so that the data volume needing to be uploaded to a remote monitoring center is very large. In this case, very high requirements are placed on network bandwidth for data uploading and real-time uploading, and at the same time, severe challenges are also created on the data storage capacity and data processing capacity of the remote monitoring center, and the challenges become more and more severe as the number of elevators to be monitored continuously increases. On the other hand, there is often a large redundancy in the data uploaded to the remote monitoring center, wherein much of the data contains the same information, and therefore the necessary data is often much smaller than the data actually collected and uploaded from the functional point of view of the desired implementation.

In addition, in the prior art, since data processing and analysis are all completed in the remote monitoring center, each event is completed by the relevant processing algorithm once, but for the data processing and analysis of the event, the correctness is usually verified only in the algorithm design stage, and is not usually verified in the subsequent algorithm application. However, in the verification process of the algorithm design stage, since the test case cannot completely cover all scenarios in the actual application, there is a possibility that the processing result is biased or even wrong due to scenarios not considered by the algorithm in the actual application. Therefore, how to implement verification of the algorithm is also a technical problem to be solved.

In view of the above, how to reduce the data uploading amount as much as possible and reduce the requirements on data uploading, storing and processing on the premise of ensuring the function implementation is a technical problem to be solved.

Example two

On the basis of the first embodiment, the present embodiment adds a local processing and storage function to the object elevator side, so that the amount of data to be uploaded can be further reduced.

Specifically, in the elevator monitoring system of the present embodiment, as shown in fig. 4, the remote monitoring center further includes:

an analysis assigning unit that determines an executor of the event to be monitored, which is one of the data processing unit of the remote monitoring center and the device-side processing unit of the elevator monitoring device, that is, the analysis assigning unit determines whether each event to be monitored is monitored by the data processing unit of the remote monitoring center or the device-side processing unit of the elevator monitoring device, based on the minimum basic data set of any one of the subject elevators output by the data determining unit and the event to be monitored corresponding to the subject elevator;

the elevator monitoring device further includes:

an apparatus-side processing means for monitoring the apparatus-side event of the target elevator by obtaining first apparatus-side event monitoring result data for an apparatus-side event to be monitored (the event to be monitored by the apparatus-side processing means of the elevator monitoring apparatus) from the apparatus-side sample data collected by the data collecting means, based on the event monitoring command received by the command receiving means;

In this embodiment, the data uploading unit may upload only the device-side sample data corresponding to the event to be monitored, which is monitored by the remote monitoring center, to the remote monitoring center, so that uploading the device-side sample data corresponding to the event to be monitored at the device side may be omitted.

The device-side storage unit may further store all device-side sample data, or may further store only the device-side sample data corresponding to the event to be monitored on the device side, so that the amount of locally stored data may be reduced.

The device-side storage unit also holds the device-side event to be monitored with the device-side processing unit as an executor and first device-side event monitoring result data for the device-side event to be monitored.

Wherein the storage unit of the remote monitoring center further holds executor information of all events to be monitored related to elevators, which records that each event to be monitored is monitored by the device-side processing unit or by the data processing unit of the remote monitoring center, and the analysis allocation unit determines the executors of all events to be monitored according to the executor information held in the storage unit.

Preferably, the data processing unit determines, according to preset attributes of the event to be monitored (such as an importance level of the event to be monitored, a processing difficulty, and a data amount required to be processed for judgment), the first device side event monitoring result data (all or part) required to be uploaded and an uploading mode (such as real-time uploading, opportunistic selection uploading), so as to reduce the data amount required to be stored by the remote monitoring center and the data amount required to be uploaded by the data uploading unit.

As shown in fig. 5, the elevator monitoring method implemented based on the elevator monitoring system includes the following steps:

The embodiment can divide the events to be monitored into events to be monitored at the device side and events to be monitored at the remote end, and simultaneously adds a device side storage unit and a device side processing unit in the elevator monitoring device, so that the events to be monitored at the device side can be locally processed at the object elevator side, and the sampling data corresponding to the events to be monitored at the remote end is uploaded to the remote monitoring center, thereby further reducing the data volume which needs to be uploaded by the elevator monitoring device and the data volume which needs to be stored and processed by the remote monitoring center.

In addition, the embodiment can upload and store the processing result and the sampling data of the event to be monitored on the device side of the local processing according to the requirement, thereby reducing the local data storage amount on the device side and the data storage amount on the remote end.

EXAMPLE III

On the basis of the second embodiment, the present embodiment adds a verification function for the local processing result of the event to be monitored on the device side.

Specifically, the device-side processing unit uploads the device-side sampling data corresponding to the device-side event to be monitored to the data receiving unit through the data uploading unit.

The data processing unit processes the device side sample data corresponding to the device side event to be monitored received by the data receiving unit to obtain second device side event monitoring result data for the device side event to be monitored, and verifies the first device side event monitoring result data received by the data receiving unit according to the second device side event monitoring result data.

And when the first device side event monitoring result data and the second device side event monitoring result data for the same device side event to be monitored are not consistent, the remote monitoring center judges whether the device side event to be monitored occurs or not according to the second device side event monitoring result, and the data processing unit modifies the model and/or algorithm stored in the device side storage unit.

As shown in fig. 6, the elevator monitoring method implemented based on the elevator monitoring system includes the following steps:

a step S7 in which the elevator monitoring device uploads the determination result obtained in the step S6 and all the device-side sample data (including device-side sample data corresponding to a remote event to be monitored that is an executor of the remote monitoring center and the device-side sample data corresponding to the device-side event to be monitored) to the remote monitoring center;

step S8, the remote monitoring center processes the device side sampling data corresponding to the remote end event to be monitored uploaded by the elevator monitoring device, and determines whether the remote end event to be monitored occurs;

The elevator monitoring device of the embodiment can upload the device side event monitoring result data obtained after local processing and the sampling data corresponding to the device side event to be monitored to the remote monitoring center, and the remote monitoring center verifies the processing result of the device side event to be monitored by the elevator monitoring device at the object elevator side, thereby ensuring the monitoring accuracy of the event to be monitored.

The present invention has been described in detail with reference to the specific embodiments, which are merely preferred embodiments of the present invention, and the present invention is not limited to the above embodiments. Equivalent alterations and modifications made by those skilled in the art without departing from the principle of the invention should be considered to be within the technical scope of the invention.
