Abstract

PURPOSE:To automatically perform the time management by providing a time counting means which measures the time of input operation at intervals of a prescribed time and giving a warning to the user of a computer system by an output device if the counted time exceeds a preliminarily determined time. CONSTITUTION:The operation of an input monitoring device 2 is controlled by an input monitoring device enable signal 40 from a processor 3, and normally, the processor 3 sets the input monitoring device 2 to the operating state simultaneously with the rise of power of the computer system. Input information inputted from an input device 1 is sent to not only the processor 3 but also the input monitoring device 2. The input monitoring device 2 measures the time of continuous input of the input device 1 and compares it with a value preliminarily set by the processor 3, and a warning interrupt signal 20 is used to interrupt the processor when the measured time exceeds this value. The interrupted processor 3 sends the continuous use time as a message to an output device 4 through an output information signal 30. Thus, the work management of the computer system is automatically performed.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to all computer systems equipped with an input device and an output device that are directly accessed by a user, and is particularly suitable for managing the continuous work of a user. input monitoring device.

[Conventional technology]

VDT workers' stress and visual acuity deterioration are 11! It has been attracting close attention as an industrial disease. As a VDT work environment, desks, chairs, lighting, etc. that take human factors into consideration are becoming more important. There, V
Limits have been added to DT's working hours, and the number of consecutive working hours per day has been set.

[Problem that the invention seeks to solve]

In many cases, time management in such a VDT work environment involves self-management such as writing notes. but,
If you manage it yourself, you have to be mindful of your time while working, which is very annoying.

The purpose of the present invention is to measure the continuous use time of work.

To automatically manage the work of a computer system by giving a warning to one worker at a certain fixed time.

[Means for solving problems]

The above purpose is to monitor continuous working time in a computer system consisting of an input device, an output device, and a processing device that processes information input by the input device and outputs output information. A system that calculates the time of continuous input, adds an input monitoring device that generates an interrupt to the processing device when the time exceeds a certain value, and outputs warning information to the worker to the output device when this interrupt occurs. This is achieved by doing so.

[Effect]

The input monitoring device uses a timer to calculate the amount of time that continuous input is being performed.

Also, if there is a break in the middle, the continuous use time is cleared, and when the continuous use time exceeds a certain time, it operates to generate an interrupt to the processing device. Thereby, the processing device
Since information indicating a warning can be output to the output device, work management of the computer system can be performed automatically.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 is a schematic block diagram of a computer system according to an embodiment of the present invention. In the configuration shown in Figure 1.

Input device! 1. Output information signal 10. Processing device 3. Output information signal 30. And output bags! ! Part 4 is the configuration of a conventional computer system. The input information input by the input device 1 is processed through the input information signal 10! ! 3
and sent to the input monitoring bag W12. Processing device! In 3,
Processes according to the received input information and outputs the output information signal 3
The present invention further includes:
The purpose is to add an input monitoring device 2. Input monitoring bag [2
The operation of the input monitoring device 2 is controlled by the input monitoring device enable signal 40 from the processing device 3. Normally, the processing device 3 makes the input monitoring device 2 operational when the computer system is powered on. Input information input from the input device 1 is sent to the input monitoring device 2 together with the processing device 3. The input monitoring device 2 measures the time during which input is continuously made using the input device. This value is compared with the value set in advance by the processing device 3, and the continuous input time is determined.
When the time becomes too large, the processing device 13 generates an interrupt using the warning interrupt signal 20 in the processing device 3. The processing device 13 that received the zero interrupt outputs a message via the output information signal 30 indicating that the continuous usage time has reached. Send to device 4.

FIG. 2 is a block diagram of the input monitoring device 2. As shown in FIG.

The input monitoring control device 21 controls the input monitoring device 2. The timer register 22 consists of a register which, when accessed by the timer and input supervisory controller 21, returns the current time and at the same time the value of the register is reset to zero. In the input register 23, the instantaneous time when input is continuously performed is set every time an input is made. Further, the no-input register 24 is set at a certain timing during which no input is performed. This operation will be explained using FIG. Furthermore, when input information is input from the input device 1 via the input information signal 10, the input information register 25 is set to 1.

FIG. 3 is an algorithm showing the operation of the input monitoring bag R2. First, when the power is turned on, the processing bag N3 sends out an enable signal and initial values to be set in the register with input 23 and the register without input 24 via the input monitoring device enable signal 40. The input monitoring control device 21 receives it.

In the "internal storage of initial values of registers with/without input" 100, initial values of registers with input and initial values of registers without input are stored inside the input monitoring control device 21.

Then, the timer register 22 is cleared to zero by the "input presence/absence initialize timer register clearer" 200, and the initial values of the input presence register 23 and the input no input register 24 are set. If there is an input, that is, if the value of the input information register 25 is 1, the process advances to 'input register countdown/no input register initialization 400. Here, the timer register 22 and the input register 2
3 is read, the former value is subtracted from the latter value, and the result is set in the input register 23.

The timer register 22 and the input information register 25.

It is automatically cleared when the value is read. Further, the initial value of the no-input register is set in the no-input register 24. These are done in parallel. Next “register with input <O”
At 600, the value of the input register 24 is determined. If YES, a 2-interrupt signal is sent to the processing device 3 and the process ends. Further, if the value of the register with input is a positive value at 600 for ``register without input'', the value returns to 300 for ``with input?''.
If there is no input at “Input present” 300, that is, if the input information register 25 is zero, the countdown proceeds to “1 input no register countdown” 500, and the timer and register 22
The value of the no-input register 24 is read, and the value obtained by subtracting the former value from the latter value is set in the no-input register 24. In this case as well, the timer register 22 and input information register 25 are cleared. and “no input register <O” 7
At 00, the no-input register 24 is determined. If it is less than zero, the process returns to "Is there an input?" 300. If the value is positive, the process returns to "initialize register with/without input/clear timer register" 200.

According to this embodiment, by using the register 23 with input and the register 24 without input, if there is a break in the middle, it is not considered as continuous work, and the actual continuous work time is measured. , it becomes possible to issue a warning to the worker. Furthermore, since the initial values of registers with input and registers without input are not fixed, they can be programmable according to the content of one work.

Also, as another embodiment, an input information register 25 and an input monitoring control device! 21 can also be substituted by a processing device.

In this embodiment, only the warning output for continuous work has been described, but the procedure is to predetermine the user number of one worker and the register for each user number, and input the user number at the time of starting one work (login). When one work is completed (logoff), by adding the value of the input register to the register of that user number, it is possible to manage work time for one day or one month.

〔Effect of the invention〕

According to the present invention, since the usage time of the computer system can be automatically measured, the VDT environment, especially the time management, can be automatically performed, which is effective for accurate management.
