Abstract

A history management system for reliably managing the history of mainly the operation of equipment such as working machines, machine tools, vehicles and a variety of molds and dies, which can be installed at a low installation cost. Each piece of equipment is furnished with a terminal in which history data including at least information on the use of the equipment are stored and in/from which history data are inputted/outputted, and data are inputted in or outputted from the terminal only when required. By this method, because terminals are mounted on the equipment, left there, and used, when necessary, to retrieve the history data including information on the use of the equipment, the system configuration is simplified. Further, because the terminal is installed as a device solely used for the management of the history of equipment, there is no need to adjust the environment of other control systems, facilitating the installation work.

This embodiment employs a system configuration including a terminal unit 1, an input / output unit 2, and a computer 3, as shown in FIG.

The terminal unit 1 is capable of inputting and outputting data relating to a history including an operation history which is at least a record of use of the device D, and is attached to the device D and is normally left unattended . Terminal 1 data is sent to the input / output unit 2. In addition to input and output, input is also made from various devices.

The input / output unit 2 is connected to the terminal unit 1 and the computer 3 only when necessary, and inputs and outputs data.

The computer 3 analyzes the data of the terminal unit 1 via the input / output unit 2. Therefore, it is not necessary to provide fixed connection lines and continuous control and control, and it is possible to install the system at low installation cost and manage the history mainly of the operation history of devices.

Fig. 2 and below show an example in which the operation history, which is a record related to the use of equipment D, is grasped as the number of operations related to the operation conditions.

The terminal unit 1 is compactly assembled in the casing 11 and attached to the equipment D, and has a count structure 12 that performs a count operation in accordance with the operation of the equipment D.

As shown in detail in FIG. 4, the counting structure 12 is mounted on a counting button 12c supported by the casing 11 via spring members 12a and 12b so as to be able to protrude and retract. A magnet 12d is provided so that the magnet 12d projects into and out of a shaft hole of a ring-shaped coil 12f supported by a magnetically permeable base 12e. Therefore, in the counter structure 12, electromagnetic induction is excited between the magnet 21 cl and the coil 12 f each time the count button 12 c appears and retracts in response to the operation of the equipment D. Will be done.

CPU 13 is connected to the power structure 12. The CPU 13 is connected to the counter structure 12 via a pulse conversion circuit 14 for converting the electromagnetic induction of the counter structure 12 into a pulse signal, and counts the number of operations of the devices D from the pulse signal. . In addition, the CPU 13 is connected to the counter structure 12 via a power generation conversion circuit 15 for converting the electromagnetic induction of the counter structure 12 into power generation and a battery 16 with a charging function to secure the operation power supply. are doing.

The memory 17 is connected to the CPU 13. Memory 17 contains data It is a non-volatile memory that does not require a power supply to hold data in the evening, and can be written to and read from the CPU 13 by counting the number of operations of the device D in both directions. Also, this memory 17 is a file in which the number of times of operation of the device D is counted for the file for each operation condition of the device D input from the input / output unit 2 via the CPU 13. Evening is being remembered.

Further, a connection terminal 18 connected to the input / output unit 2 is connected to the CPU 13. Since the connection terminal 18 has a small data transmission / reception scale between the terminal unit 1 and the input / output unit 2, a wireless structure such as infrared rays can be employed in addition to a wired structure.

The input / output unit 2 includes the same CPU 21 and memory 22 as the terminal unit 1 so that data can be transmitted to and received from the terminal unit 1. The CPU 21 is connected to a wired / wireless connection terminal 23 connected to the terminal unit 1 and a wired / wireless connection terminal 24 connected to the computer 3. The operating power supply for the CPU 21 can be either a battery or an AC power supply.

The input terminal unit 25 has a structure sufficient to allow input of numerals, keys, alphabets, and the like using numeric keys and switching keys. From the input terminal 25, the identification of the device D and the operation date, repair, modification, failure, inspection, etc., the execution date, etc. can also be input. Can be supported. The contents input and supported by the CPU 21 are transmitted to the terminal unit 1 and finally written and input to the memory 17 of the terminal unit 1 or read from the memory 17. Output.

The display terminal unit 26 displays the input contents at the time of input from the input terminal unit 25 and displays the data received from the terminal unit 1 as it is. Therefore, a display of several digits and several columns by a liquid crystal is sufficient.

The output terminal unit 27 prints the input contents of the input terminal unit 25 and the data received from the terminal unit 1. Therefore, it is sufficient to print only figures, kana and alphabets.

The computer 3 can be a personal type (called a personal computer as of 1997) used for simple office work in ordinary households and businesses. The computer 3 includes a modem for transmitting and receiving data to and from a communication system such as a local area network, the Internet, or the like.

According to this embodiment, for example, as shown in FIG. 3, the terminal button 1 of the counting structure 1 is provided on the PL surface of equipment D composed of an injection molding die apparatus in which the die is frequently opened and closed. It is mounted through a suitable heat insulating structure so that 2c can appear and disappear. In this example, the number of times the mold is opened and closed by the injection molding mold apparatus is counted as the number of operations. In addition, the entire terminal unit 1 is formed in a cassette type so that it can be easily attached to and detached from the equipment D, or the memory 17 of the terminal unit 1 is formed in a force type to easily attach to the terminal unit 1. It can be configured so that it can be attached and detached and connected to and disconnected from the input / output unit 2 easily.

The terminal unit 1 attached to the equipment D does not require an external power supply, and is not required to be incorporated in other control systems or to maintain a constant connection with the input / output unit 2 and the computer 3. Therefore, it can be easily mounted on the equipment D.

Since the terminal unit 1 attached to the device D does not require an external power supply, the terminal device 1 automatically counts and stores the number of operations of the device D. And

When data stored in the terminal unit 1 is required, the input / output unit 2 can be connected to the terminal unit 1 and data can be extracted from the input / output unit 2. Further, the data extracted and stored in the input / output unit 2 is displayed and confirmed on the display terminal unit 26, and is transferred to the computer 3 for advanced analysis or communication with another system or the like by communication. It will be used between them. Therefore, the number of operations of the device D can be reliably grasped in relation to the operation conditions, and the operation history of the device D can be reliably managed.
