Abstract

The monitor is configured to detect its malfunction by deviating the value of its internal temperature from the set value. In this case, automatic control of the temperature of the screen unit 1 is provided in case the temperature value determined by the sensor 2 installed on the screen unit 1 is found outside the specified range of temperature values. The processor unit, based on a comparison of the temperature value obtained from the sensor 2 with the limit values located in the memory 5, changes the power supply mode of the backlight 3 of the screen unit 1.

Description

The technical field to which the utility model relates.

The utility model relates to the diagnosis of monitors (displays).

State of the art

Currently, the widespread use of monitors (displays) in payment and information terminals, also called self-service terminals, to display on-screen information of interest to the client. Self-service terminals are a means of remote access to the server network of self-service terminals, which acts as a payment or information system. The lack of information on the monitor screen makes it impossible to use the services of these systems through the appropriate terminal.

At the same time, the monitor described in the utility model RU 58278 dated November 10, 2006 is known that is configured to detect a malfunction of the screen unit by deviating its temperature values from the set value and including a temperature sensor mounted on the screen unit and connected directly to the monitor processor unit, made with the possibility of transmitting information about the temperature of the screen unit to an external device with respect to the monitor. The disadvantage of this known device is that although it provides for the transfer of information about the temperature of the screen unit, it does not provide adjustment of the temperature of the screen unit to be within specified limits, guaranteeing operability

screen block. And the identification at a distance from the self-service terminal of the temperature of the screen unit beyond the permissible limits without the possibility of adjusting the temperature makes the arrival of operators (repairmen) pointless.

Utility Model Disclosure

For those who operate a network of self-service terminals, it is important to immediately learn about the termination of the display of information on the monitor screen installed in the self-service terminal. Therefore, it is important to timely detect the lack of information display by the monitor, requiring the intervention of maintenance personnel. In this case, it is advisable to exclude from the number of reasons leading to a violation of the display of information on the monitor screen that the temperature of the screen unit is outside the permissible limits.

The technical results achieved in the claimed utility model consist in obtaining information about the monitor’s operability, taking into account that the temperature values of the screen unit are within the limit values, and if the temperature value is outside the limits in the automatic restoration of the temperature value of the screen unit.

An important circumstance is that the processor unit, designed to control other units (nodes) of the monitor, receives information about the temperatures of these units, which makes it possible to judge their serviceability and serviceability of the monitor as a means of displaying information in general. However, it is necessary to take into account external conditions for the monitor, for example, weather, essential for the screen unit. It is also important to exclude the influence of external temperature conditions on the performance of the monitor when ensuring

monitoring the health of its blocks by temperature values. This is precisely what is achieved in the claimed utility model.

The indicated technical results are provided in a monitor configured to detect a malfunction of the screen unit by deviating its temperature values from the set value and including a screen unit, a power unit, a processor unit, at least one temperature sensor mounted on the screen unit and connected directly to the unit monitor processor, which is configured to transmit information about the temperature of the screen unit to an external device with respect to the monitor, a memory for storing temperature values of the screen block and made with the possibility of adjusting the temperature of the screen block according to the instructions of the processor block, made with the possibility of comparing the temperature values of the screen block with the limit temperature values stored in the memory.

The monitor may include several temperature sensors installed on several blocks of the monitor, the termination of each of which will lead to the termination of the display of the information received by the monitor, and connected to the processor unit, configured to transmit information about temperatures measured by temperature sensors. The number of temperature sensors may exceed the number of monitor units on which they are installed. In particular, on a screen unit having a different surface temperature value. In addition, more than one sensor on one block can be installed to increase the reliability of determining the deviation of the current temperature of the block from the set. In particular, temperature sensors can be installed on the monitor screen unit and power supply.

In the monitor, the screen unit may include a liquid crystal screen and backlight connected to the power unit, while the power unit is connected to the processor unit to switch the power modes of the backlight unit of the screen unit.

The processor unit can be configured to block its video input, through which information from the computer enters it, if it is detected that the temperature limit of the screen unit is exceeded. When the temperature of the screen block is outside the limit values, it is advisable to automatically restore the temperature value of the block within the limit values. And since it is impossible to display information with a monitor, it is also advisable to block the video input until the temperature of the screen unit is restored to the limit values.

A memory for storing the temperature limits of the screen unit may be included in the processor unit. In this case, the processor unit may be configured to compare the temperature values received therein. The memory of the processor unit can provide storage of the results of comparison of current temperatures, including with the given values. Then, when connected to a computer, the monitor can provide the transfer of the results of comparing current temperatures to it. The transfer of the comparison results will indicate the operability of the monitor processor unit. The processor unit may include a central processor that controls other monitor units, and a video processor that commutes and converts the video signals.

The monitor can include a video processor made in a separate unit, and temperature sensors can be installed on the screen unit, power supply, and video processor unit.

Brief Description of the Drawings

Figure 1 shows a block diagram of a monitor.

Utility Model Implementation

Figure 1 shows the monitor screen unit 1 with a temperature sensor 2 and backlight 3, a processor unit 4, a memory 5, a power supply 6, a power supply for the backlight 3 of the screen unit 1, and a temperature sensor 7. If any of these blocks fails, the information on the monitor screen will not be displayed. Temperature sensors 2 and 7 are connected directly to the processor unit and are installed, respectively, on the screen unit 1 and the power supply unit 6.

To process data coming directly from temperature sensors 2 and 7, a “standard” processor unit 4 of the monitor is used, reprogrammed accordingly. The processor unit 4 is equipped with a memory 5 and can, for example, transmit data on the results of comparing temperature values to the computer of the self-service terminal, which in turn reports them to the server of the self-service terminal network to notify the service operation of the network of self-service terminals.

The processor unit 4, having determined that the temperature of the screen unit 1 is negative, blocks the video input of the monitor and gives a command to the power supply unit 6 to heat the screen unit by increasing the radiation power of the backlight. You can use other means of adjusting the temperature of the screen unit, for example, means of blowing the screen unit with hot air or strip heating elements mounted on the housing of the screen unit.

After a certain time or after receipt of positive temperature values from the temperature sensor 2 from the temperature sensor 2, the block

the processor unlocks the video input and the monitor starts working normally.

If the temperature of the screen block is higher than the limit (50 ° C for the liquid crystal matrix), the processor block turns on the energy saving mode (reduces the incandescent lamps by 30-40%, or reduces the frequency of the processor, or gives a command to lower the temperature of the blower, or turns on the fan.

When automatically restoring the temperature of the screen unit within the limit values, for example, due to a change in the operating mode of the power supply, changes in the temperature of the screen unit will not be a consequence of its malfunction, and this is important to consider when analyzing information received by the device external to the monitor.
