Description

  The present invention relates to a method for monitoring the temperature of a server computer.

  2. Description of the Related Art Conventionally, a problem has been known that the temperature in a server room in which a server computer is installed is measured and an abnormal state such as a rapid temperature rise is monitored. At present, a system that monitors temperature by using a temperature sensor provided at intervals of several meters is widely used for this problem. In this system, even if the temperature monitoring alarm reports an abnormality, it is difficult to specify which position of the server computer has an abnormality. For this reason, for example, technical developments such as Patent Documents 1 and 2 have been performed.

Patent Document 1 discloses a technique in which a temperature sensor is provided at a predetermined position of a server rack and the temperature change of each temperature sensor is monitored. Patent Document 2 includes an imaging device that captures a visible image, a temperature sensor that measures a temperature within the field of view of the imaging device, and a display that displays the visible image. A technique is disclosed in which an image is divided and displayed in a grid pattern, and division lines are color-coded according to temperature measurement values in each division area measured by a temperature sensor.
JP 2005-309742 A Japanese Patent No. 3634845

However, in the technique disclosed in Patent Document 1, in order to detect a detailed temperature distribution for each server computer, a plurality of temperature sensors are required for each server computer, so the setting of the apparatus becomes complicated. . In the technique disclosed in Patent Document 2, when a large number of server computers are monitored, a monitoring device corresponding to the number of the server computers is required. In addition, since the data of the visible image is large, it is difficult to perform data processing in real time.
The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a technique capable of monitoring the temperature of a server computer relatively easily with less complexity.

  In order to achieve the above object, a temperature monitoring method for a server computer according to a first invention is a method for monitoring the temperature of a plurality of server computers installed in a server room, and (1) the plurality of server computers. (2) a position data storage step for storing the position of each server computer in the server room in the computer as three-dimensional position data based on the data obtained by the position measurement step; (3) a temperature measuring step of measuring each server computer with an infrared camera based on the position data and acquiring temperature data; (4) a position of the server computer when the temperature data exceeds a predetermined threshold value; And a notification step for generating a notification signal including That.

In the present invention, the position measurement step is preferably performed using a three-dimensional scanner.
The temperature measurement step is preferably performed by a movable robot that can move in the server room and is equipped with an infrared camera. Alternatively, the temperature measurement step is preferably performed by a plurality of fixed infrared cameras installed in the server room.
Moreover, it is preferable that the notification step is performed through e-mail.
According to the present invention, first, the installation positions of a plurality of server computers are measured (position measurement step). A three-dimensional scanner can be used to measure the installation position of the server computer. The three-dimensional scanner can acquire distance information to the object.

  Next, based on the data obtained in the position measurement step, the position of each server computer in the server room is stored in the computer as three-dimensional position data (position data storage step). In this location data storage step, in addition to the location information of each server computer, the internal structure of the server room (including the location information of the wall surface, the unevenness of the wall surface, and structural information such as objects other than the server computer) It is preferable to construct a virtual space and store these three-dimensional data. Since the three-dimensional position of each server computer in the server room is known by the position data storing step, it is not necessary to take a visible image of the server computer when performing the temperature measuring step, and the temperature data obtained by operating the infrared camera is eliminated. It is sufficient to perform only the process. For this reason, it is not necessary to process visible image data as compared with the technique of Patent Document 2, so that the processing speed can be improved. Once the location data is saved, it is not necessary to perform the location measurement step and location data storage step unless the installation location of the server computer or the internal structure of the server room is changed. Yes.

  Next, based on the position data, the temperature of each server computer is measured with an infrared camera to obtain temperature data (temperature measurement step). At this time, when a fixed infrared camera is used, temperature data can be taken at any time (or continuously), which is a useful embodiment particularly in an environment where the temperature change is severe. In addition, a movable robot that can move in the server room and is equipped with an infrared camera can be used. As such a movable robot, for example, a self-propelled robot including a computer that controls a travel route based on position data can be used. Specifically, a Segway robot platform can be used. By using such a movable robot, temperature measurement can be performed with a small number of infrared cameras, which is more economical than fixing a large number of infrared cameras. In addition, since it is possible to go through the path between server computers without any problems, there are fewer places that can be seen as shadows of other objects.

  Next, when the temperature data exceeds a predetermined threshold value, a notification signal including the position of the server computer is issued (notification step). Examples of the notification signal include a warning (alarm) by sound and notification by e-mail. In the present invention, the position of the server computer that has become hot is limited to a narrow range (for example, “the back side of the hard disk installation location inside the server computer installed at a certain position”, “daughter board near the server computer installed at a certain position” ”,“ Near the third slot from the bottom of the server computer installed at a certain position ”, etc., so that more detailed correspondence is possible.

A temperature monitoring device for a server computer according to a second aspect of the invention monitors the temperature of a plurality of server computers installed in a server room, the three-dimensional scanner for measuring the installation position of the server computer, An infrared camera that measures the temperature data of the server computer, and the position of each server computer in the server room is stored as three-dimensional position data based on the data acquired by the three-dimensional scanner, and the infrared camera includes the temperature data. A monitoring computer that displays an image and compares the temperature data with preset comparison data, and the position of the server computer when the temperature data is higher than the preset comparison data A notification device that generates a notification signal including Characterized in that was.
The infrared camera is preferably mounted on a movable robot that can move in the server room, and the temperature data is preferably transmitted to the monitoring computer via a wireless LAN.

  According to the present invention, it is possible to provide a method and apparatus capable of monitoring the temperature of a server computer with less complexity and relatively easily.

Next, embodiments of the present invention will be described with reference to the drawings. However, the technical scope of the present invention is not limited by these embodiments, and various forms can be made without changing the gist of the invention. Can be implemented. Further, the technical scope of the present invention extends to an equivalent range.
In FIG. 1, the outline | summary of the temperature monitoring apparatus 1 of this embodiment was shown. The temperature monitoring device 1 is for monitoring the temperature of a plurality of server computers 2 installed in the server room 3. The current server room 3 uses a very large space (for example, a space of several hundred square meters or a space provided on multiple floors of a building), and a rack having a large number of server computers 2. 4 is installed (see also FIG. 3).

The temperature monitoring device 1 includes a three-dimensional scanner 10 (hereinafter also referred to as “3D scanner”) that measures the installation position of the server computer 2 and the server room 3 based on data acquired by the 3D scanner 10. Are provided with a monitoring computer 12 that stores the position of each server computer 2 as three-dimensional position data, and an infrared camera 11 that measures temperature data of each server computer 2 based on the position data.
Further, the temperature monitoring device 1 is provided with an alarm device 21 that emits a notification signal including the position of the server computer 2 at which the abnormal temperature is reached when the temperature data becomes higher than preset comparison data. It has been. As shown in FIG. 5, the monitoring computer 12 is provided via a LAN 20 via a wireless LAN access point 19.

  The monitoring computer 12 has a general configuration (for example, a configuration provided in a normal computer such as a CPU, RAM, ROM, motherboard, daughter board, and hard disk). Among them, typical ones will be described as follows. Data (including position data and temperature data) transmitted from the 3D scanner 10 and the infrared camera 11 is input to the monitoring computer 12 via the I / O port 13. These various data are processed by the arithmetic processing unit 14 and then recorded on the recording device 15 (for example, a hard disk). The display data output from the arithmetic processing unit 14 is displayed on the display 18 through the I / O port 17 after passing through an appropriate encoder 16.

  FIG. 2 shows a movable robot 22 equipped with the infrared camera 11. As such a movable robot 22, for example, a Segway robot platform can be used. The movable robot 22 includes a pair of drive wheels 24 provided on both left and right sides of the gantry 23, a motor (not shown) for moving the drive wheels 24 in both the front and rear directions, and an auxiliary wheel 25 provided at the front end of the gantry 23. Is provided. A control computer 26 for controlling the movement of the movable robot 22 is provided on the upper surface side of the gantry 23. The control computer 26 controls the movement of the movable robot 22 along a preset monitoring route T (shown only in FIG. 4) based on the position data of the server computer 2. The motor and the control computer 26 can be driven by a battery (not shown) for a predetermined time. For this reason, the movable robot 22 can move on the monitoring route T without being connected to an electric wire or the like.

A support shaft 27 extends upward on the rear end side of the gantry 23, and a pair of upper and lower shaft bodies 28 extend from the support shaft 27 toward the front. An infrared camera 11 is installed on the upper surface side of each shaft body 28. Image data (including temperature data) captured by the infrared camera 11 is transmitted to the monitoring computer 12 via the LAN 20 via the wireless LAN device 29 and the access point 19.
FIG. 3 shows a state in which a plurality of server computers 2 are installed in a rack 4 in the server room 3. 4 shows a route T through which the movable robot 22 passes between the racks 4 in the server room 3 shown in FIG. When the movable robot 22 actually moves between the racks 4, the infrared camera 11 is set to move while appropriately changing the direction so that the server computer 2 of the rack 4 can be photographed. Yes.
The photographing route of the infrared camera 11 will be described as follows. About each server computer 2, the part which can confirm temperature by one imaging | photography and the part which becomes a shadow of another member (The other server computer 2, the rack 4, the wall surface of the server room 3, etc.) generate | occur | produce. Here, the more shadows there are, the more places (moving steps of the movable robot 22) that must actually be taken. Regarding the photographing of the temperature of the server computer 2 by the infrared camera 11, an appropriate fixed point M is used as a reference when processing by software. The fixed point M is a point that appears in the image pickup Xv when the infrared camera 11 takes a picture from a certain place X, and also appears in the image pickup Yv taken from a place Y different from the place X. Means. As the fixed point M, a point on the server computer 2 can be used, or an arbitrary point for other things (for example, the rack 4, the server room 3, an electric lamp, etc.) can be used. By taking a picture while moving the infrared camera 11 (that is, the movable robot 22) with reference to such a fixed point M, and performing a merge in the processing of electronic data using the fixed point M as a reference, a small number of infrared cameras 11 are used. The temperature data of each server computer 2 can be obtained without shadows.

  FIG. 5 shows an outline of a temperature monitoring system including the temperature monitoring device 1. Data from the infrared camera 11 of the movable robot 22 is transmitted to the monitoring computer 12 via the LAN 20 via the wireless LAN device 29 and the access point 19. Connected to the LAN 20 is an alarm device 21 (notification device) that issues a notification signal when abnormal heat is generated. In addition, the LAN 20 is connected to an external network 30 (for example, the Internet), and sends out a notification signal (including location information of the server computer 2 in which abnormal heat generation has occurred) as an e-mail through the external network 30. Can do. This e-mail is received via the external network 30 by a computer 31 of a person who should receive the signal (for example, a management company, a manager in charge, etc.) or a mobile phone 32.

Next, the flowchart of this embodiment is demonstrated, referring FIG.6 and FIG.7. FIG. 6 shows a process from measuring the installation position of the server computer 2 to storing the position data. In this step, a 3D scanner 10 (for example, manufactured by Z + F (Germany)) can be used. Initial information for operating the 3D scanner 10 (including data collection angle, data measurement speed, etc.) is input to the monitoring computer 12 and initial settings are made (S100). The position is measured (S110). In this position measuring step, in addition to the server computer 2 and the rack 4, the internal structure such as the inner wall position and the uneven position of the server room 3 is also measured. In addition, in the case of collecting data from only one place, if there is a shadow part, data is collected at a plurality of places, the internal structure of the server room 3 becomes clear, and a 3D model can be built inside the computer 12 Collect original data. Next, the collected original data is processed to calculate three-dimensional data (S120).
In this step, the position of the server computer 2 is identified from the original data, the server computer 2 is identified, the internal structure of the server room 3 is identified. The calculation of the three-dimensional data can be performed by the following method, for example. First, the surface of an object such as the server computer 2, the rack 4, or the inner wall of the server room 3 is created from the original data (point cloud). Next, modeling of each object is performed based on the surface data. About modeling, it is brought close to the real thing by performing evaluation and correction according to the actual object. Finally, a modified surface (three-dimensional data) is created from the original data.
Thus, the calculated position data is stored (S130). Through the position data storage step, a three-dimensional virtual model of the server room 3 is created inside the monitoring computer 12 (see, for example, FIG. 3). By going through the steps shown in FIG. 6, the same position data can be used until the internal structure of the server room 3 changes. For this reason, in this embodiment, when collecting temperature data, visible image data is not required.

Thus, after the step shown in FIG. 6, the step shown in FIG. 7 is performed. In this step, the temperature of each server computer 2 is actually measured, and in a predetermined state, an alarm is generated or an e-mail is notified. Based on the position data stored in the monitoring computer, the movement of the movable robot 22 along the monitoring route T along with the shooting of the infrared camera 11 is programmed (see, for example, FIG. 4). In addition, conditions for transmitting temperature data photographed by the infrared camera 11 via a wireless LAN are set (S200). At this time, before actually measuring the temperature data, by performing calibration, the temperature of the server computer 2 is determined by absolute comparison between the current room temperature and the temperature data obtained by the infrared camera 11. It can be calculated.
Thus, after completing the initial setting, temperature measurement by the movable robot 22 is started (S210). In the temperature measurement step, image data including temperature data is collected by the infrared camera 11 while the movable robot 22 moves between a large number of server computers 2 according to a predetermined time. This data is transmitted to the monitoring computer 12 via the LAN 20. In the monitoring computer 12, the temperature of the server computer 2 is continuously monitored. FIG. 8 shows the image data collected by the infrared camera 11 and processed with software to add temperature data.

  The monitoring computer 12 compares the temperature data with a preset threshold value (comparison data) (S220). Here, when the former is lower than the latter (when there is no abnormality in the temperature data), a temperature measurement step for processing the image from the infrared camera 11 is performed as it is (S210). On the other hand, when the temperature data becomes higher than the comparison data, a notification step is performed (S230). In the notification step, the alarm device 21 is uttered to notify that an abnormality has occurred, the position of the server computer 2 where the abnormality has occurred, and an e-mail including the position information of the server computer 2 where the abnormality has occurred is sent out (notification) signal). At this time, as the position information, more detailed information than before (for example, “the back side of the hard disk installation location inside the server computer installed at the specific position”, “near the daughter board of the server computer installed at the specific position”, Or, by adding information such as “near the third slot from the bottom of the server computer installed at a specific location”, the person who moves to the server room 3 is required to stop the abnormality. Since it is possible to prepare in advance such devices (for example, a specific board, a hard disk of a specific model number, etc.), a more detailed response is possible.

As described above, according to the present embodiment, it is possible to provide a technique capable of monitoring the temperature of the server computer with less complexity and relatively easily.
