DETAILED DESCRIPTION OF THE INVENTION

In the following detailed description of the implementation of the invention, numerous implementation details are provided to provide a clear understanding of the present invention. However, qualified in the subject area a person skilled in the art, it will be obvious how the present invention can be used, both with and without these implementation details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to unduly obscure the features of the present invention.

Moreover, it will be clear from the foregoing that the invention is not limited to the present implementation. Numerous possible modifications, changes, variations and substitutions that retain the spirit and form of the present invention will be apparent to those skilled in the subject area.

The proposed method for automatic assessment of the reliability, completeness and quality of the performance of the work by the performers (100) is shown in Fig.1.

Each service unit (103) is marked with a digital identifier.

The service unit (103), in the materials of this application, refers to any equipment, premises that need to be serviced, for example, but not limited to, industrial equipment.

Under the digital identifier, in the materials of this application, is understood any digital label known from the prior art, which can be read by hardware, for example, but not limited to RFID - tag, QR code, geolocation position.

For each service unit (103), a work list is created containing operations and the order in which operations are performed on the service unit.

Each work is strictly regulated by the list of works, which determines which operations and in what order must be carried out to achieve the proper quality of work. The list of work is formed on the basis of a typical technical card with the addition of operations on the history of equipment operation.

The performer (101), before starting work, performs identification in the application on the fixation device (102), entering his personal login and password. From the moment of identification, the executor's working time is recorded (101), the beginning and end of the executor's working time (101), as well as the beginning and end of the work of each operation according to the list of works, is recorded. The fixing device (102) is automatically sent a list of works assigned to be performed directly by the performer (101) for the current day, or the performer (101) selects works from the list of available ones (works are offered for equipment at technical places to which the performer is admitted and has relevant qualifications). Each job in the job list contains the ID of the equipment for which the job was created.

Under the fixation device (102), in the materials of this application, is understood, but not limited to, a mobile phone, tablet, HMI - panel.

The executor (101) selects the job and reads, by the fixation device (102), the digital identifier on the service unit (103) for which the job is intended.

When the service item ID specified in the selected job and the service item ID (103) match, the performer (101) performs it, sequentially marking each operation. Thus, work is carried out only on the necessary equipment. The work operations describe the actions that must be performed during the execution of the work and the actions to confirm the reliability and quality of the work execution: reading the digital identifier, photographing, making comments, etc. When the work is performed, the fixation device fixes: the start / end time of the entire work as a whole and each operation separately, the geolocation position at the beginning and end of the work (if available on the fixation device).

Additionally, it is possible to set the fixing of weather conditions for a given area (ambient temperature, atmospheric pressure, wind speed, relative humidity) three times a day. Data on weather conditions are also a criterion for determining the reliability of work, for example, the pouring of a pipe piston installation (oil equipment) is carried out outdoors and only with water, that is, the ambient temperature must be positive, and to ensure quality (metrology requirements) not lower than +15 °C, if this work is marked as carried out at a negative temperature, then such work can be considered unreliable and of poor quality.

In the proposed solution, it is also possible to record data from the performer’s life control devices in order to obtain data to assess the reliability of the work performed, for example, if the intended work is associated with physical activity, then the performer’s pulse should increase, if the performer imitates the performance of work, then the pulse will remain the same. In addition, recording data from the life control devices of the performer is aimed at determining the safety of the work, for example, automatic algorithms can assess the state of the employee and prohibit dangerous work (at height, under voltage, etc.). All recorded data for each job, as well as files and documents created in the process of performing the job, are transferred in real time to a reliable event registration database with blockchain technology (U4).

In a private implementation, in the absence of a network, all recorded data is stored on the fixation device (102), and the accumulation of recorded data is ongoing, and data is exchanged with a reliable event registration database (104) at the time of network availability.

The recorded data for each job from the fixation device (102) is stored in a reliable event logging database with blockchain technology (104), which completely excludes the possibility of editing and deleting data, providing a mechanism for checking the integrity. All events are interconnected by a chain of hash sums and copies of the database are formed by all interested parties (it is possible to form an arbitration escrow copy on an independent storage source). As a reliable event registration database (104), the event registration database disclosed in RU patent No. 2704532 published on October 29, 2019 can be used.

Additionally, data from related information systems (for example, a system for recording equipment operation, a weather data system, a system for automated admission of personnel to an object, a traffic control system, and others) are recorded in a reliable event registration database (104). Data from information systems are used in the assessment of reliability.

After receiving a message from a valid event logging database (104) about the completion of work and the presence of recorded data, the algorithms for evaluating the reliability are automatically launched. For the assessment, criteria are predetermined, the fulfillment of which means that the work has been completed in full and at the appropriate level of quality. The algorithms are executed on a computing device or in the cloud (105).

As criteria for the completeness and quality of work performance, for example, but not limited to, the following criteria can be set: compliance of the digital identifier with the one required in the work; time of execution of work or a separate operation; compliance with the state of the equipment (disabled, in operation, etc.); the nature of the work being done (under load, on disconnected equipment); the presence of facts of photo-video fixation; compliance of weather conditions with the nature of the work; compliance with the geographic position during the work.

Criteria are set in advance and in any quantity.

Each criterion has a reduction factor that is predetermined. For example, if a photo is not taken, then you can set the reduction factor to 10% (perhaps the performer forgot to take a photo), and if there was no voltage on the equipment, then the reliability is 0%, because. the contacts were not exactly checked (do not touch them under voltage). And so for each criterion. By applying the coefficients consistently, a final confidence score is obtained.

As a result of applying the method, the end user receives an assessment of the reliability of the completeness and quality of work performance and events accumulated as a result of execution (106).

Based on the data received, the work can be recognized as completed or not completed (when the reliability of the completeness and quality of the specified value is reached) in automatic mode with further processing. Examples of further processing may include, but are not limited to: re-appointment for execution with unsatisfactory reliability; inclusion of reliable works in various reports; formation of the cost of performance of work, construction of a picture of the working day of the performer, etc.

Access to the results of the assessment of reliability and the accumulated data is carried out through the web interface or export/import using software protocols (106).

Next will be described an example of selecting criteria for the work associated with removing the casing of the device and performing actions with the contacts of the device, which must be turned off the voltage.

The criteria for evaluating the reliability in this case will be the following.

1. Reading the digital identifier of the device (it is determined whether the performer is located next to the device, and does not simulate work in the "utility room").

2. Checking the geolocation position (if the device is serviced locally, the geolocation of the place must be checked, and if it must be removed and transported, for example, to the laboratory, then the geolocation of the laboratory).

3. Time of execution of the operation "Removing the casing". The time cannot be short (for example, at least 1 minute). 4. The presence of a photo taken after removing the casing (i.e., an open casing is fixed, and the performer understands that if the manager sees the photo later, then it must be with the casing removed. That is, if the work is carried out with simulation, then the photo will not be made).

5. Obtaining information from a third-party system (APCS) about the presence of voltage on the device. This criterion is important since it is impossible to touch the contacts under voltage, which means that work was not performed in the presence of voltage.

6. If special equipment is used (for example, a voltage indicator), then this may also be marked with a digital identifier and the operation may require reading this digital identifier. Criteria - the read digital identifier of the special equipment.

After fixing the data on the work associated with removing the casing of the device and performing actions with the contacts of the device, an automatic algorithm for checking the reliability is launched, and the assessment is made according to the above criteria.
