4. Requirements to ergonomics and technical aesthetics

The shape and the way the information shall be determined by its composition and purpose.

Information about the abnormal situation in the system should be displayed on the screen in a manner that attracts the attention of the staff.

General ergonomic requirements for AWM ACSEE must meet DSTU 7299: 2013 "Design and Ergonomics. Operator. The relative position of the workplace. General requirements Ergonomics"

Design solutions and the quality of their implementation shall meet the requirements of technical aesthetics.

Ergonomic solutions should provide ease of operation, maintenance and repair of equipment.

5. Requirements for the operation, maintenance, repair and preservation of the system components

In areas where the equipment is located ACSEE SS, should be provided with the operating conditions according to the requirements that are set in the operating instructions on the device and means.

Mode ACSEE SS - continuous, non-stop with periodic maintenance.

Maintenance ACSEE SS should be two types of:

• Operational Services;

• routine maintenance.

The main type of repair should be carried out by replacing the faulty unit with spare parts. Next repair faulty units is carried out by the personnel operating the system, or at specialized repair shops.

6. Requirements for the protection of information from unauthorized access

Protection should be the organizational and technical means of limiting access to specific users. As part of protection should be provided for software data protection, which allow:

• access control system operators to tasks, reports, parameters and system resources;

• control of data integrity and system configuration;

• registration and recording of operator actions.

It must be ensured limiting user access to tasks of manual data entry. Manual data entry must have the appropriate signs and details of the manual input operator.

To protect against unauthorized access must be provided:

• organizational solutions (limiting access of unauthorized persons to the premises, which houses the equipment ACSEE);

• physical protection (lock and seal on products, special cabinets, safes);

• programming techniques (setting passwords, placing applications and data in the write-protected memory areas), creation of groups (profiles) of users in terms of access - administration, review and manual data entry, data revisions;

• Measures to protect against changes in the information in the files of data that is stored on external media.

7. Requirements for the preservation of information in case of emergencies

There must be measures that ensure the renewal or minimize data loss due to the influence of factors that caused the emergency and hardware failures. Measures to protect and restore the information shall be provided at the level of software, as well as wearing the organizational and technical nature (to use RAID arrays on the server, backup server, "hard" copies of software and data duplication while preserving information).

As part of the system of technical means shall be provided to the external memory, which ensure the safety of the software, information files and the possibility of subsequent recovery. It shall be capable of manual or automatic backup.

Safety information should be provided by ACSEE SS under the following emergency situations:

• temporary power failure;

• temporary failure of cable lines and equipment data, the duration of which does not exceed the operating time in standalone mode;

• failure of individual hardware ACSEE SS.

In emergencies system must not give out false signals and information.

In the event of failure of the main power supply, computer hardware systems must go powered by uninterruptible power supply unit and perform safe shutdown in automatic or manual mode.

Resuming after failures and accidents in the system should be carried out in automatic or automatic modes.

Electricity meters in the loss of power and / or failures of communication channels should ensure the preservation of information in non-volatile memory (the primary database) for the period in the amount of pre-fault load schedule at least 45 days with the integration period of 30 minutes. In addition, electricity meters, which have digital interface must provide safety indicators at the beginning of the day, during the day, at the beginning of the month - for the month.

Programmes meter reading should include mechanisms for monitoring the completeness of the data and their reading with safety regulations.
