Abstract

PURPOSE:To reduce the CPU load of a host computer by controlling a communication transmitter used between the host computer and an equipment so that an optional part of a main memory contained in the host computer is transferred to an optional part of a main memory contained in an intra-equipment controller and vice versa. CONSTITUTION:Each equipment is connected to a host computer 100 via communication units 107 and 207 and the information files stored in memories 106 and 206 and used for control are mapped in real time by both units 107 and 207. In other words, the computer 100 contains the information files of all equipments to be controlled within the memory 106. These information are replaced by the unit 107 which is independent of the main CPU of the computer 100. Thus, it is not required for the main CPU to perform the communication processing for transfer of information needed for the control of the group of equipments. As a result, the CPU load is reduced for the computer 100.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a device for managing and controlling one or more pieces of equipment using a host computer.

BACKGROUND ART Conventionally, when a host computer manages and controls one or more pieces of equipment via a communication transmission device, the host computer uses a CPU to send and receive data or commands for managing and controlling the equipment. A program for data transmission/reception processing and its analysis/judgment processing was provided.

Problems to be Solved by the Invention In the above-mentioned conventional devices, the host computer analyzes programs and commands for sending and receiving data or commands to and from the equipment, and then assembles the data to be sent as a result. There is a problem in that the processing requires a large number of programs, and the CPU load for the processing is large.

Means for solving the problem In order to solve the above problem, a transmission device for communication between the host computer and the equipment is used to transfer any part of the main memory in the host computer to any part of the main memory of the controller in the equipment. With the above configuration, the present invention is characterized in that it can be transferred to a part of the computer and can also be transferred in the opposite direction.
Equipment-side data can be obtained without performing transmission/reception processing that imposes a load on the PU, and management information can be sent to equipment simply by writing the management information to any memory. Therefore, the load on the CPU of the host computer required for analysis and judgment of management information when the host computer sends and receives data or commands to manage and control equipment is significantly reduced.

EXAMPLE Hereinafter, an example of the present invention will be explained using FIGS. 1 to 4.

First, FIG. 1 shows an example of equipment managed and controlled by a host computer. This example shows a process of drawing a resistor paste on a raw material substrate for circuit formation (hereinafter referred to as a substrate). Each piece of equipment, here the resistance drawing apparatus, is arranged in a line, and the substrate passes through each piece of equipment while undergoing processing, and then passes through all the pieces of equipment to complete the resistor paste drawing process. An example of the process is shown in FIG.

Each facility consists of a host computer (1oo) and a communication unit (10).

That is, as shown in FIG. 1, the host computer 100 has in its memory 106 information files for all the equipment that it manages and controls. The information is updated by a communication unit 107 independent from the main CPU of the host computer 10o. Therefore, the main CPU does not need communication processing for exchanging information necessary for managing and controlling the equipment group.

FIG. 2 is an example of information files for managing and controlling each facility in the host computer 100. As described above, this example is for a case where the host computer 100 is used to manage and control a circuit forming process using a plurality of drawing apparatuses.

FIG. 3 shows the information file that each piece of equipment has.

The information files shown in Figures 2 and 3 are communications 22 SO)
107 and 207, it is mapped in real time to the memory in the host computer and equipment.

FIG. 4 is a block diagram of the processing system on the host computer 100 side, and the controller 2oO on the drawing device side, which is each equipment.
It is a processing system block diagram of. First, the processing system on the upper computer side will be explained.

Upper computer 100 for managing and controlling equipment group
The operator can know the operating status of the equipment group to be managed and controlled via the display device 101. If the state of the equipment is abnormal with respect to the target, a control command is input via the input device 102. The man-machine interface unit 103 exchanges information with the processing system inside the host computer and the operator via the display device and input device. The equipment management section 104 searches the information file mapping memory 106 at a certain time period or when requested by an operator, and passes information such as equipment status or production results to the man-machine interface section. The equipment control unit 106 writes the operator's control command to the information file mapping memory location for the equipment.

Next, I will explain the processing system block diagram on the equipment side. The operator of the in-equipment controller 200 uses the display device 20
1, you can know the operating status of your own equipment. Further, via the input device 202, it is possible to input a command to request necessary data from the host computer or to notify the operating status of the own device. Facility management department 20
4. Provide the latest information on the operating status of own equipment, production results, etc.
The information file mapping memory 206 is updated at the timing when the information changes. The in-equipment control unit 206 controls the equipment to a certain state based on commands transferred from the host computer to the information file mapping memory, and passes the resulting information to the man-machine interface unit.

As described above, in the present invention, when a plurality of equipment is managed and controlled by one host computer 100, the CPU load on the host computer 100 can be significantly reduced.

In other words, the meaning and structure of information for managing and controlling the equipment is determined in advance, and the equipment side writes the latest information such as production results, equipment operating hours, equipment operation errors, etc. to the information file in its own memory. . The information is mapped by the transmission unit 207 to the memory 106 in the host computer 100 in real time. On the host computer 1oo side, the information mapped in its own memory 106,
Search the operating file of the equipment, and if there is a change in the information, perform processing according to the change. As a result of the processing, if it becomes necessary to send some kind of command from the host computer side to the equipment, the command is sent from the host computer 100 to the equipment controller 200 at a predetermined position in the information file in its own memory. Write the command to be executed. On the equipment side, similarly, the operating film of the equipment mapped in its own memory is searched, and the same processing as that of the host computer 100 is performed. This eliminates the need for transmission/reception processing, analysis, and judgment processing by the CPU of the host computer 100, and the load on the CPU is reduced.

Next, as a specific example of the above control method, processing when the production quantity is reached will be described.

First, it is assumed that the actual number of substrates produced in the drawing apparatus &m (1≦m≦n) matches the planned number. At that time, in the information file mapping memory 206 in the drawing device, the equipment status is RUN → STORE - 77' equipment mode is in operation → switching board production is,
Planned = Actual data changes are made. These states are transmitted in real time by the communication unit 207 to the information file mapping memo! of the host computer. Device 7! is moved to a position of 2m inside J106. On the other hand, upper computer 1
The 00 side learns of the change in the equipment status of equipment Am,
Next, we investigate the cause of the change and learn that a changeover request has been issued in equipment Am due to reaching the production quantity. Therefore, on the host computer side, the next production board name and NC data are sequentially written into the data in the device according to the production schedule. When all data for switching is sent to the drawing device side, board production is performed in the 4-information file mapping memory 106 in the host computer 100.

All 9 hours of module production and equipment errors are cleared to 0, and instructions for reset and start are sequentially written to the host computer. On the drawing device side, a reset command from the host computer 100 changes the equipment mode from Switching to Running, and the next start command changes the equipment status from Stop to Run.
The next production begins.

Effects of the Invention As described above, according to the present invention, management and control using a host computer of a group of equipment can be achieved.

Main C of host computer and equipment controller
The communication load for PU information exchange is significantly reduced.

Therefore, it becomes possible to utilize the load of the main CPU, which is handled by the communication unit, for other processing. For example, the processing speed of the man-machine interface section can be improved.
