A fault detection module is used to detect in real time whether a fault occurs during the operation of the elevator, and a fault signal is issued when the elevator fails. The signal is transmitted by the signal transmission module to the blockchain network for signal analysis. The present invention simultaneously establishes a topological structure through the blockchain network, and the parsed word segmentation features correspond to the fault points in the topological structure. The corresponding fault points are marked with features, and then connected to the blockchain network through a multi-channel signal connection module to realize signal fault sharing, and the alarm of the corresponding position is completed synchronously. Compared with the existing technology, the present invention realizes effective grasp of the fault through real-time detection of components, and can stably issue alarm signals. At the same time, since the signal is directly connected to the blockchain, the shared connection of multiple signals is realized, which solves the problem of the property management department's failure to make an emergency response in time.

Description

Technical Field

[0001] The present invention relates to the technical field of elevator safety, and in particular to an elevator safety operation system based on a blockchain network. Background Art

[0002] Elevators, a common means of transport for people going up and down stairs in shopping malls and office buildings, are located within the building's elevator shaft and are driven by a lifting drive mechanism and guide rails. Elevators experience wear and tear over time, and severely worn elevators can easily cause accidents during high-speed up and down travel. Therefore, improving elevator safety is a critical priority for the elevator industry.

[0003] When an elevator malfunctions during operation, trapping people inside, existing safety measures typically involve installing an alarm button at the elevator keypad. Pressing the button by the trapped person triggers an alarm signal. However, the manual communication technology used in this technology cannot guarantee a stable alarm signal. Furthermore, because the alarm signal is typically only transmitted directly to the property management department, there is a risk of delayed emergency response due to management oversight. Summary of the Invention

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0006] Therefore, the technical problem solved by the present invention is: to solve the problem that the human communication technology used in the existing elevator safety protection technology cannot guarantee the stable issuance of alarm signals on the one hand, and on the other hand, since the alarm signals are generally only directly transmitted to the property management department, there is a problem of not making emergency responses in time due to management negligence.

[0008] As a preferred solution of the elevator safety operation system based on the blockchain network described in the present invention, the fault detection module detects in real time whether a fault occurs during the operation of the elevator through a single-layer operation rate calculation unit embedded in the center of the top of the elevator car, specifically including the following steps: S1: A signal transmitter is configured at the top of each floor of the elevator shaft; S2: A signal receiver that receives the signal sent by the signal transmitter is embedded in the single-layer operation rate calculation unit; S3: When the elevator runs to the corresponding floor, the signal receiver receives the corresponding signal in real time; S4: The built-in processor of the single-layer operation rate calculation unit obtains the interval time of signal reception on each floor in real time, and obtains the single-layer rate change ratio based on the uninterrupted interval time; S5: It is defined that when the single-layer rate change ratio reaches a threshold, the elevator fails and sends a fault signal.

[0009] As a preferred solution of the elevator safety operation system based on the blockchain network described in the present invention, the threshold value of the single-layer rate change ratio is 0.1.

[0010] As a preferred solution of the elevator safety operation system based on the blockchain network described in the present invention, the fault signal contains three layers of segmentation, namely: fault elevator segmentation, fault floor segmentation and warning segmentation.

[0011] As a preferred solution of the elevator safety operation system based on the blockchain network of the present invention, the blockchain network receives the fault signal, which includes the following steps: S1: using Scrapy cloud to crawl the fault signal; S2: temporarily storing the fault signal in each small sub-crawler file; S3: using Flume to aggregate the temporarily stored fault signals into the master node; S4: when the aggregation is completed, storing them in the corresponding HDFS directory, waiting for the blockchain network access end to analyze and collect them;

[0012] When storing in a corresponding HDFS directory, the storage directory is defined as the word segmentation feature.

[0013] As a preferred solution of the elevator safety operation system based on the blockchain network described in the present invention, the blockchain network analyzes the fault signal including the following steps: based on a preset algorithm, performing a feature summary on the fault signal, wherein the summary is defined as the word segmentation feature; accessing the blockchain network through the multi-channel signal connection module to realize data sharing; sending the summary to the blockchain network for evidence storage, and receiving the returned transaction address of the current summary evidence; forming a data packet with the transaction address, the summary and the fault signal, and generating each data node on the blockchain network.

[0014] As a preferred solution of the elevator safety operation system based on the blockchain network described in the present invention, the blockchain network is Ethereum or Hyperledger.

[0015] As a preferred solution of the elevator safety operation system based on the blockchain network described in the present invention, the process of saving data acquisition requests is saved on the blockchain network nodes.

[0016] Beneficial effects of the present invention: The present invention provides an elevator safety operation system based on a blockchain network, which detects in real time whether a fault occurs during the operation of the elevator through a fault detection module, and sends a fault signal when the elevator fails.

Compared with the existing technology, the present invention achieves effective grasp of the fault through real-time detection of components, and can stably send out alarm signals.

[0023] When an elevator malfunctions during operation, trapping people inside, existing safety measures typically involve installing an alarm button at the elevator keypad. Pressing the button by the trapped person triggers an alarm signal. However, the manual communication technology used in this technology cannot guarantee a stable alarm signal. Furthermore, because the alarm signal is typically only transmitted directly to the property management department, there is a risk of delayed emergency response due to management oversight.

[0025] The fault detection module 100 detects in real time whether a fault occurs during the operation of the elevator and sends a fault signal when a fault occurs;

[0026] The signal transmission module 200 is signal-connected to the fault detection module 100, receives the fault signal, and transmits the fault signal to the blockchain network 300;

[0027] The blockchain network 300 establishes a topological structure based on the elevator floor layout, connects to the signal transmission module 200, receives the fault signal, parses the fault signal, extracts the word segmentation features in the fault signal, and simultaneously matches the fault point in the topological structure based on the word segmentation features, and features the corresponding fault point;

[0028] The multi-channel signal connection module 400 is provided with multiple signal channels, all of which are connected to the blockchain network 300 signal, obtain the feature tags in real time, and send the feature tags to multiple terminals;

[0029] The alarm module 500 is connected to the multi-channel signal communication module 400, receives the characteristic mark at the multi-channel terminal, and issues an alarm for the elevator operation according to the fault point corresponding to the characteristic mark.

[0030] For further information, see Figure 2 The fault detection module 100 detects whether a fault occurs during the operation of the elevator in real time through a single-layer running rate calculation unit embedded in the center of the top of the elevator car. Specifically, the following steps are included:

[0031] S1: A signal transmitter is installed at the top of each floor of the elevator shaft;

[0032] S2: The single-layer operation rate calculation unit is internally embedded with a signal receiver that receives the signal sent by the signal transmitter;

[0033] S3: When the elevator reaches the corresponding floor, the signal receiver receives the corresponding signal in real time;

[0034] S4: The processor built into the single-layer operation rate calculation unit obtains the interval time between signal receptions at each layer in real time, and obtains the single-layer rate change ratio based on the uninterrupted interval time;

[0035] S5: When the rate change ratio of a single floor reaches a threshold, the elevator fails and sends a fault signal.

[0036] Specifically, the threshold value of the single-layer rate change ratio is 0.1.

[0037] Specifically, the fault signal contains three levels of segmentation words, namely: faulty elevator segmentation words, faulty floor segmentation words and warning segmentation words.

[0038] For further information, see Figure 3 , the blockchain network 300 receives the fault signal including the following steps:

[0039] S1: Use Scrapy cloud to crawl the fault signal;

[0040] S2: Temporarily store the fault signal in each small sub-crawler file;

[0041] S3: Use Flume to aggregate temporarily stored fault signals to the master node;

[0042] S4: When the aggregation is completed, it is stored in the corresponding HDFS directory and waits for the blockchain network 300 access terminal to analyze and collect;

[0043] When storing in the corresponding HDFS directory, the storage directory is defined as the word segmentation feature.

[0044] For further information, see Figure 4 , the blockchain network 300 analyzes the fault signal including the following steps:

[0045] Based on the preset algorithm, the fault signal is summarized, and the summary is defined as the word segmentation feature;

[0046] Accessing the blockchain network 300 via the multi-channel signal connection module 400 enables data sharing;

[0047] Send the summary to the blockchain network 300 for storage, and receive the returned transaction address of the current summary storage;

[0048] The transaction address, summary and fault signal thereof are combined into a data packet and each data node is generated on the blockchain network 300.

[0049] It should be noted that the preset algorithm is specifically a hash algorithm. This is merely an example and not a limitation. For example, user A uses a hash algorithm to calculate a digital digest for each piece of information in a shared dataset. Common hash algorithms include MD5 and the SHA series.

[0050] Additionally, the blockchain network is Ethereum or Hyperledger.

[0051] Additionally, the process of data acquisition request is saved on the blockchain network nodes.

[0052] The present invention provides an elevator safety operation system based on a blockchain network. A fault detection module is used to detect in real time whether a fault occurs during the operation of the elevator, and a fault signal is issued when the elevator fails. The signal is transmitted by the signal transmission module to the blockchain network for signal analysis. The present invention simultaneously establishes a topological structure through the blockchain network, and the parsed word segmentation features correspond to the fault points in the topological structure. The corresponding fault points are marked with features, and then connected to the blockchain network through a multi-channel signal connection module to realize signal fault sharing, and synchronously complete the alarm of the corresponding position. Compared with the existing technology, the present invention achieves effective grasp of the fault through real-time detection of components, and can stably issue alarm signals. At the same time, since the signal is directly connected to the blockchain, the shared connection of multiple signals is realized, which solves the problem of the property management department's failure to respond to emergencies in a timely manner.
