  • the controller When dusting the surface, the reflected light changes and changes are recorded. Upon reaching the critical value of the surface state change, the controller generates a signal about the need for maintenance. Additionally, the use of the ATMEGA 88 controller allows you to expand the functionality of the sensor to inform by performing the following functions (which were not in the prototype):
  • Registration ⁇ Hourly account - after the power appears on the Vporta or upon receipt of the start command (depending on the settings), the sensor starts to count the time elapsed since the start.
  • the data is stored in the non-volatile memory of controller 3 and cannot be changed without interfering with the sensor construct; the time of each next session is added to the existing value.
  • Watchdog timer - provides automatic computer restart in the event of an operating system freeze. This is ensured by periodically sending a software package for maintaining life to the sensor. If the operating system stops sending packets, it means it is frozen and the sensor reboots the computer hardware.
  • Tamper sensor with support for the counter freezes - when you open the cover of the computer, a mechanical contact is activated and the sensor detects the operation.
  • the sensor collects information about the autopsy and the total number of autopsies. This allows not only to detect the fact of opening the case, but also to understand whether all openings were authorized. ⁇

  • conditional scale - dust state The interaction of the PC operating system (OS) with the device connected to it via the USB interface is provided by the program on the PC, which conducts a cyclic poll and displays the dust level according to the conditional scale (conditional scale - dust state, expressed as a percentage: from 0% (no dust) to 100% (full dust)).

  • the hours worked counter allows you to carry out equipment maintenance on time, to find out the real time of the system for controlling bodies.
  • Opening control allows you to instantly notify the system administrator of an unauthorized opening of the case and take timely action. Automatic reboot in case of unauthorized opening of the case allows you to reset the current OS session and prevent information leakage.
  • the tamper-evident counter allows the system administrator to find out if the case was opened unauthorized.
  • Dust control is based on a change in the reflective ability of a surface when it is dusted.

Le résultat technique consiste en une plus grande fiabilité de fixation du capteur grâce à l'exclusion d'un film collant et une fixation indépendante fiable du capteur de poussière. Le capteur servant à indiquer la nécessité d'effectuer l'entretien d'un dispositif, notamment informatique, comprend un moyen de détection distant. Ce moyen comprend un émetteur et un récepteur de rayonnement IR. Le capteur capteur servant à indiquer la nécessité d'effectuer l'entretien d'un dispositif comprend également une carte sur laquelle est disposée une unité de commande (ATMEGA 88) à laquelle est connecté le moyen de détection. Le capteur peut utiliser une connexion USB afin de recevoir une alimentation et d'échanger des informations. La carte est fixée sur le connecteur USB. Le moyen de détection est installé à l'aide d'une connexion à boulon.
