Wherein the terminal 11 communicates with the server 12 through a network, and the server 12 communicates with the target blockchain platform 13 through the network. The server 12 receives an evaluation result acquisition request transmitted by the terminal 11; the evaluation result acquisition request carries an account identifier corresponding to the maintenance personnel; the server 12 generates an evaluation information acquisition instruction according to the evaluation result acquisition request, sends the evaluation information acquisition instruction to the target blockchain platform 13, and triggers the target blockchain platform 13 to return evaluation information corresponding to the account identifier; the target blockchain platform 13 is used for acquiring a request according to an evaluation result, tracing from the blockchain network according to an account identifier, and acquiring prestored evaluation information corresponding to the account identifier; the block chain network is pre-stored with elevator operation data, fault information and the like acquired from a main control system, historical maintenance information and the like acquired from a maintenance terminal carried by a maintenance person, qualification information and the like related to the maintenance person; the server 12 carries out corresponding evaluation information processing according to the evaluation information to obtain an evaluation result of the maintenance personnel; the server 12 sends the evaluation result of the maintenance person to 11. The terminal 11 may be, but not limited to, various personal computers, notebook computers, smartphones, tablet computers, and portable wearable devices, and the server 12 may be implemented as a stand-alone server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, a method for obtaining a maintenance personnel evaluation result based on a blockchain is provided, and the method is applied to the server 12 in fig. 1 for illustration, and includes the following steps:
The account identification is identification information of the maintenance personnel in the blockchain network and corresponds to the identity information of the maintenance personnel one by one. The server may associate the account identifier with the identity information of the maintenance person, e.g. the terminal may query the server for the account identifier associated with the identity card number by the identity card number of the maintenance person.
Specifically, after establishing communication between the terminal and the server, sending an evaluation result acquisition request to the server, detecting the evaluation result acquisition request by the server, judging whether the evaluation result acquisition request contains an account identifier capable of identifying the maintenance personnel, and if the evaluation result acquisition request does not contain the account identifier, returning result information that the evaluation result acquisition request is invalid to the terminal.
If the evaluation result acquisition request sent by the terminal does not contain the account identifier capable of identifying the maintenance personnel, but contains other identifier information capable of identifying the maintenance personnel, and the other identifier information has an association relationship with the account identifier, the server can determine the corresponding account identifier according to the other identifier information, or the server can directly replace the other identifier information in the evaluation result acquisition request with the account identifier.
The method comprises the steps that a server determines a target object to be subjected to evaluation result acquisition through an evaluation result acquisition request which is sent by a receiving terminal and contains account identification; meanwhile, the account identifier is associated with other identifier information, so that the terminal can generate and send an evaluation result acquisition request to the server only by knowing at least one identifier information capable of identifying maintenance personnel, the difficulty in acquiring the evaluation result is reduced, and the accuracy of the evaluation result is improved.
The block chain is a distributed shared account book and database, and has the characteristics of decentralization, non-tampering, whole trace, traceability, collective maintenance, disclosure transparency and the like; the blockchain network comprises a series of blocks (blocks) which are connected with each other according to the generated sequence time, new blocks can not be removed once the new blocks are added into the blockchain, and record data submitted by nodes in the blockchain system are recorded in the blocks. The target blockchain platform is a service platform capable of accessing the blockchain network, and can create blockchain accounts according to different applicable objects and allocate account identifications corresponding to the blockchain accounts.

Because the blockchain network has the characteristics of tamper resistance, disclosure transparency and the like, the data obtained by the server from the blockchain network are true and reliable, and the obtained evaluation result is also accurate and can reflect the true maintenance level of the maintenance personnel.
Specifically, after the server generates a corresponding evaluation information acquisition instruction according to an evaluation result acquisition request sent by the terminal, the server can encrypt and sign the evaluation information acquisition instruction and send the processed evaluation information acquisition instruction to the target blockchain platform; and the target blockchain platform performs consensus verification and decryption through relevant nodes in the blockchain network according to the evaluation information acquisition instruction so as to store the information acquisition operation through the blockchain network and acquire the evaluation information corresponding to the account identifier from the blockchain network.

Specifically, the evaluation information processing may include various processing modes such as classifying, weighting, calculating score, classifying and the like of the evaluation information, and may be set according to actual needs.
For example, a preset evaluation item list may be obtained, where the list includes multiple items of evaluation information that are required for each evaluation item; and obtaining corresponding item scores according to the multiple items of evaluation information, and carrying out weighted summation on the scores of all the items according to the weights corresponding to the items to obtain total scores which are used as evaluation results of maintenance personnel.
The item score may be obtained by calculating a standard score, which is the quotient of the difference between the original and average scores divided by the standard deviation. For example, the raw scores form a set { x } 1 ，x 2 ，…，x n Average score of }
Standard deviation of
Then for any one of the original scores x i Let the name->
Is x i Standard components of (2); weighting the standard and the corresponding weight of each itemAnd obtaining the total score of each maintenance person;
after the score of a certain project of the maintenance personnel is calculated, the total score of the maintenance personnel can be calculated as an evaluation result of the maintenance personnel by the following method:
T all ＝W 1 ·T 1 +W 2 ·T 2 +…+W n ·T n +W n+1 ·T n+1 ；
Wherein T is all To maintain the total score of personnel, W 1 -W n+1 For each item, corresponding weight, T 1 -T n+1 A score for each item; the corresponding weights of the respective items can be adjusted according to the evaluation period.
Further, the ranking of the total score of a certain maintenance person among a plurality of maintenance persons can be used as the evaluation result. The grades can be further classified according to the scores of the maintenance personnel, and the grades are used as evaluation results.
The step is to process the evaluation information to obtain the evaluation result of the maintenance personnel; acquiring unmodified maintenance information in a blockchain network with the maintenance information stored in advance, so as to evaluate maintenance personnel and obtain an evaluation result; the data obtained through the block chain network is true and reliable, and the accuracy of the obtained evaluation result is high.
And step 24, sending the evaluation result of the maintenance personnel to the terminal.
Specifically, after acquiring the evaluation result of the maintenance personnel, the server transmits the evaluation result of the maintenance personnel to the terminal corresponding to the transmission evaluation result acquisition request. When the server sends the evaluation result of this time, the server can also send the historical evaluation result data to the terminal together, or generate an evaluation result report according to the evaluation result of this time and the historical evaluation result, and the report records the change condition of the evaluation result of the maintenance personnel in the past, so that the change condition of the maintenance level of the maintenance personnel can be reflected.
According to the maintenance personnel assessment result acquisition method based on the block chain, the assessment result acquisition request sent by the receiving terminal is received; the evaluation result acquisition request carries an account identifier corresponding to the maintenance personnel; generating an evaluation information acquisition instruction in response to the evaluation result acquisition request, sending the evaluation information acquisition instruction to a target blockchain platform, and triggering the target blockchain platform to return evaluation information corresponding to the account identifier; the target blockchain platform is used for acquiring the evaluation information corresponding to the account identifier from the blockchain network according to the evaluation information acquisition instruction; performing corresponding evaluation information processing according to the evaluation information to obtain an evaluation result of the maintenance personnel; and sending the evaluation result of the maintenance personnel to the terminal. According to the method, through account identification, unmodified maintenance information is obtained from a blockchain network in which the maintenance information is stored in advance, so that maintenance personnel can be evaluated, and an evaluation result is obtained; the data obtained through the block chain network is true and reliable, and the accuracy of the obtained evaluation result is high.

According to the embodiment, the block corresponding to the evaluation information is positioned, so that the evaluation information corresponding to the account identifier can be quickly acquired, and the efficiency of acquiring the evaluation information is improved.
In one embodiment, as shown in fig. 4, the step 23 performs corresponding evaluation information processing according to the evaluation information to obtain an evaluation result of the maintenance personnel, and includes:
and 43, carrying out operation processing on the characteristic information according to the characteristic weight to obtain an evaluation value corresponding to the account identifier, and taking the evaluation value as an evaluation result of the maintenance personnel.

In one embodiment, as shown in fig. 5, the step 21, before receiving the evaluation result acquisition request sent by the terminal, further includes:
and 52, collecting maintenance personnel information, maintenance record information and elevator operation information corresponding to the account identification, taking the maintenance personnel information, the maintenance record information and the elevator operation information as evaluation information, and adding the evaluation information to the maintenance information account through the target blockchain platform.
