Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer management apparatus, and more specifically, to efficiently use a computer itself or a network, as opposed to a computer alone or a network formed by a plurality of computers. Management device for.

[0002]

2. Description of the Related Art Conventionally, as management of a computer, for example, when an event has not occurred in the computer for a certain period of time, a screen saver, auto power off, etc. are used to save power and reduce consumption of equipment. There is something.

Further, in information transmission, communication is sequentially performed in a waiting order, or mail information is sent by designating a destination, and the receiving side indicates on screen display that information is sent from another computer. , There is one that makes it possible to recognize that there is a mail addressed to oneself and read the mail information immediately after logging in.

[0004]

However, when the computer is actually used, the operator is left absent because the computer is started up or the logged-in state is still in use and the operation is continued. It may end up. Even in such a case, in the conventional device, there is a loss because the saving state cannot be entered until a certain time has elapsed. Moreover, even if the event does not occur for a certain period of time, the operator may be sitting in front of the computer thinking about the next event to be input, and in such a case, the saving state is entered. Is not practical, and as a result, the above-mentioned fixed time for shifting to the saving state is set to be relatively long and relatively long, so that the above problem becomes more remarkable.

Also, when sending a mail, the destination
In other words, the recipient does not always exist, and even if the recipient is logged in as described above, he or she may be absent. The communication load may increase due to unnecessary communication, resulting in an overload. Moreover, if the user is absent even when logged in, it becomes unclear on the sending side when the receiving side reads the mail information.

The present invention has been made in view of the above background, and an object thereof is to be able to shift to a saving state in a relatively short time and to suppress an unnecessary increase in communication load. , To provide a computer management device capable of efficiently using a cornputer network.

[0007]

In order to achieve the above object, in a computer management apparatus according to the present invention, a man-machine for inputting data from an operator or presenting data to the operator. In a computer system having an interface section, a detection means for detecting whether or not the operator is at a position for operating the man-machine interface section, and controlling the operation content of the computer system based on the detection result of the detection means. And a control means.

[0008]

When the operator is at the operating position of the computer, that is, the man-machine interface, it is the case that the data input processing such as the specific key input is not performed (the event input is not made for a certain period of time). However, it can be determined that the operation is being performed while the input is being prepared or thinking. On the contrary, when the operator is not in the predetermined place, it can be determined that the operation is not performed. Therefore, the presence / absence of the operator is detected by the detection means, and it is determined whether or not the computer is in operation based on the detection result.
Controls what the computer does. More specifically,
As such control, for example, when it is determined that the computer is not operated, the computer is put into a power saving state, or the mail information can be read when the operator is absent, so that the mail information transmitted to the computer is transmitted. It is to stop. The time required for the above determination is relatively short because it is possible to directly know that the operation / processing is not performed by detecting the absence of the operator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of a computer management apparatus according to the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a block diagram showing the overall configuration of an embodiment of the present invention.
As shown in the figure, a host station A and a terminal (each terminal device) B are linked, and the host station A is connected to other host stations and terminals to form a communication network.

In the host station A, an input device 1 including a keyboard 1a and a mouse 1b for inputting login and other information as an external device and an output device 2 such as a display are connected via a bus. Further in the present invention,
The human body detection sensor 3 as a detection means is also connected to the bus, and can detect whether or not there is an operator in front of the host station A, that is, a computer having a man-machine interface section (operation position). As for the human body sensor 3, the operator sits on a chair or the like during a normal operation and therefore is located at a substantially fixed position, and further, the operator cannot maintain the same posture for a long time and slightly moves while sitting. Therefore, it is preferable to use a fuzzy applied human body sensor that determines the presence / absence of a human body by fuzzy inference based on comprehensive information obtained from a plurality of types of sensors such as a pyroelectric sensor and a photoelectric detector. It is not limited to.

On the other hand, in the internal device of the host station A, that is, inside the computer, a machine load condition measuring device 4, a communication load condition measuring device 5, a data registration management device 6, a save mode shift / cancel device 7 as a control means, and a process. The assignment determining device 8 and the mail information transfer time determining device 9 as the control means are connected to each other via a bus. The machine load condition measuring device 4 and the communication load condition measuring device 5 among the above devices detect the load of the machine in the host station A and the communication load due to the data communication performed between the communication networks, respectively. Since a conventionally known device is used, description of the specific configuration is omitted.

Next, the specific configurations (functions) of the respective devices 6 to 9 and their actions will be described together. * Data Registration Management Device 6 As shown in FIG. 2 (A), this device 6 controls the exchange of data with the database 10 connected to this device, and the specific processing is as follows. There is one.

The login name from the input device 1 such as the keyboard 1a, the host name input from the input device 1 or another database, and the terminal name are registered in the database 10. The “presence / absence” data of the operator sent from the human body sensor 3 is registered in the database 10. The load status data sent from the machine load status measuring device 4 is registered in the database 10. Based on the data request signal sent from another device, necessary data is taken out from the database 10 and output to the device.

These four functions are properly implemented independently of each other in relation to other devices. It should be noted that FIG. 1B shows a storage state of data in the database 10. * Save Mode Transition / Cancellation Device As shown in FIG. 3 (A), this device 7 has a timer as a basic configuration, operates according to information obtained from other devices, and operates when there is no operator for a certain period of time. The control signal is output to the device for shifting to the save mode to bring it into the saving state. The specific operation is as shown in the flowchart of FIG. 7B, and is performed by the following procedure.

That is, first, the time-up value is set by the signal received from the input device 1. When there is an "absence" signal generated when the human body presence sensor 3 detects the absence of the operator, the timer 3a starts and counts up. When the set time-up value is reached, the save mode is entered. A control signal is output so that each device can enter the saving state. However, the communication system is ready for operation.

As described above, even if the human body detection sensor 3 is not present, the save mode is not immediately changed to the save mode after a certain period of time. Even if the operator detects the absence of the operator, it may cause a false detection, and in the actual data access processing, the operator may not be in front of the computer for a short period of time for various reasons during the operation. This is because after leaving, there are many cases where they return immediately and continue processing. Therefore, the time-up value is determined in consideration of the above circumstances, but the presence / absence of the operator, which is directly connected to the determination as to whether or not the operation is possible (possible), is directly detected, and the control is performed based on that. Therefore, it is possible to set the time sufficiently shorter than the fixed time in which no event occurs, which is a factor for entering the power saving state in the related art.

When an event is input from various devices, it can be determined that the operator is present (in operation).
When the input signal is received, the timer is reset, and if it is already in the save mode, the release signal is output.
The criterion for resetting may be not only the event input described above but also the time when the human body detection sensor 3 re-detects the presence of the operator, or both may be used together.

* Processing Assignment Determining Device As shown in FIG. 4, in the present device 8, when a new process occurs, it is judged whether or not the process can be processed by the own station. It determines which of the other host stations in the network is to perform the above process. The specific process is as follows.

First, when a new process is input from the input device 1, the data management device 6 is requested to present the data of the current machine load condition of the own station and receives the data of the own station. Then, in the present device, it is determined whether the received load of the own station is equal to or less than a certain value, and when the load is less than the certain value, it is determined that the own station performs processing, and a processing determination signal is output, The above processing is performed using another device of the own station.

On the other hand, when the load exceeds a certain value, in order to determine another station (other host station, terminal, etc.) on the network to perform processing instead of the own station,
Requests and receives the data of the machine load status of another station successively from other stations that can log in. Then, it compares the received data and searches for a station that has less machine load than its own station and a small number of logins. Then, when there are a plurality of relevant stations, the station with the least machine load and the smallest number of logins is selected, and it is determined that the station should perform the above processing. If there is no station whose machine load is lower than that of the own station, the own station decides to perform the process. Then, the processing determination signal is output and the above processing is performed using a predetermined station. Incidentally, this device is not particularly an essential device of the present invention,
It is not necessary to install it.

* Mail Information Transfer Time Determining Device As shown in FIG. 5 (A), this device 9 is used when a mail transmission process occurs due to the determination of the process allocation determining device of the input device 1 or another host station. In order to efficiently transfer it to a predetermined destination, the specific processing is as shown in the flowchart of FIG. 6, and is performed according to the following procedure.

First, in this example, the processing is performed in the order in which the mail processing occurs, and when a new mail processing occurs, it is added to the end of the processing queue as shown in FIG. 5B. Then, the following processing is performed on the mail information at the head of the processing queue. That is, the destination data of the mail information, more specifically, the "presence / absence data" at the destination terminal or host station is requested and received. Then, if there is a destination (operator on the receiving side), the transfer of the mail information is determined and a determination signal is output. Based on this determination signal, the mail information is sent to the desired destination via the network according to the usual process.

On the other hand, when the other party is absent in the above process, the communication load status data between the current networks registered in the database 10 is stored in the computer management device 4.
Request and receive that data. Then, if the communication load status data is equal to or less than a certain value, transfer is determined and mail information is sent. The reason why the message is sent in this case is that even if the operator is absent in front of the computer, the operator may actually be in an operable state just by detecting the absence for the above-mentioned reason. Even if, as a result of the transmission, the mail information is not read out by the receiving side and communication is impossible, if the communication load is low, other events are less affected and practically no problem occurs.

If the received communication load status data exceeds a certain value, it is determined that the transfer has not been performed, the mail information is re-registered at the end of the above processing queue, and the next queue is waited for. The above processing is performed on the mail information. After that, the above operation is repeated.

On the side of the terminal having no internal device, the same process as the above process is performed using the external devices 1 to 3 owned by itself and the internal devices 4 to 10 of the host station connected thereto. Be seen.

[0026]

As described above, in the computer management apparatus according to the present invention, it is detected whether an operator is present in front of the computer, the operation contents of the computer system are controlled based on it, and the mail information is sent. Since the presence / absence of the transmission process is determined, it is possible to consume the equipment and save the power without loss. Also, it becomes possible to reliably transmit the mail information to the other party. Further, it is possible to prevent communication overload due to unnecessary communication, which enables efficient use of the network.
