Description

SENSOR FOR INFORMATION

ON THE NEED FOR MAINTENANCE OF THE DEVICE.

The utility model relates to the field of improving the operational reliability of electronic equipment and is intended to determine the state of a computing device or device, mainly the degree of dust, as well as to determine the tamper, etc. its internal components, and timely reporting of the need for maintenance. The device can monitor a personal computer, server equipment, information terminal.

Dust inside the device may cause it to overheat and fail.

One of the main factors determining the need for urgent prevention of the hardware of a computer is the level of dust. A computer with internal fans (coolers) draws dust from the surrounding air. This dust accumulates in the PC system unit and settles on the computing elements, which leads to their overheating, and also spoils the moving parts. Timely cleaning of the insides of the system unit significantly reduces the likelihood of breakdowns and extends the life of the computer.

The frequency of preventive maintenance is to a certain extent related to the conditions of the room and the actual time of work in which computer equipment operates, and these conditions can vary greatly. Today there is no single method by which it would be possible to determine with what frequency to service a particular device in a particular room.

A known sensor for informing about the need for maintenance of a device, mainly a computing one, containing a reading device, which is actually a dust sensor, including an emitter and an IR spectrum receiver, a board on which a controller is installed, to which a reading device is connected and which is configured to use USB for power supply and information exchange (D-Sensor manufactured by Ural Computer Engineering CJSC of computer equipment; http: // a vtomatix.ru/catalog354.htm), the reader is attached on adhesive tape to the base of the housing. However, such a mount is not reliable. In addition, the adhesive layer of the tape loses its properties over time. In this case, in case of violation of the integrity of the mount and unnoticed detachment of the sensor, the latter may begin to give indications of the state of the device area, the degree of dust of which differs from the initial installation area of the sensor. As a result, information about the need for maintenance of the device will be incorrect.

The task to which the creation of this utility model is aimed is to increase the reliability and reliability of informing about the need for maintenance of instruments and devices.

The technical result is to increase the reliability of mounting the sensor by eliminating the use of adhesive tape and a separate reliable fixing of the reader.

The technical result is achieved due to the fact that in the sensor for informing about the need for maintenance of the device, mainly a computing device, containing a reader, including an emitter and an infrared receiver, a board on which a controller is installed, to which a reader is connected, and which configured to use USB to receive power and exchange information, the board is mounted directly on a USB header, and the reader is remote with the ability to install Sheaths using a bolted connection.

The sensor uses an ATMEGA 88 controller.

In FIG. 1 shows a general view of the sensor; FIG. 2 presents a schematic diagram of the proposed sensor.

The sensor for informing about the need for maintenance of the device, mainly computing, contains a remote reading device 1 (dust sensor). The means 1 includes an emitter 1a and a receiver 16 of the IR spectrum. The sensor for informing about the need for maintenance of the device also contains a board 2 on which a controller 3 (ATMEGA 88) is installed, to which a reader is connected. The sensor for informing about the need for maintenance of the device is configured to use USB to receive power and exchange information. The board 2 is mounted directly on the USB header 4. The reader 1 is installed using a bolted connection. The sensor works on the principle of changing the reflectivity of a surface when it is dusted. The emitter 1a illuminates a small area of the analyzed surface, and the receiver 16 measures the level of reflected light. 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. }

Power is supplied from the internal USB port of a personal computer (PC) and an independent built-in power supply. It can work in the environment of MS Windows XP, MS Windows Vista, MS Windows 7, (no COM ports are created), as well as an operating system of the Linux family. No specialized drivers are required for operation (the standard USBHID driver is used). The sensor does not form and does not require any COM ports.

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 system administrator independently selects and sets the required critical dust level in whole units, for example, 58%).

Thus, the device can be used as part of a personal computer, server equipment, information terminal and monitors the state of dustiness of the surface onto which the reading element is mounted. This avoids the effects of dusty electronic equipment - overheating, the accumulation of static electricity, leading to the failure of electronics. Hover control allows you to reboot the device in the event of a freeze and thus reduces downtime when performing critical tasks with unstable equipment.

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.

Control over freezing is implemented by periodically sending heartbeat packets from the program to the sensor, and if the sensor does not receive the packet, the computer automatically reboots automatically.

2) The device monitors system hangs. In the event of a hang, the device reboots the system (starting with FW50).
