Unmanned diagnostic communications system for computer controlled machine tools.

* This invention relates to a machine-controlled machine, and in particular an unmanned diagnostic apparatus, to automatically analyze computer-controlled, machine-operated, or machine-operated operations.

With the progress of the computer controlled machinery and the machining operations eternally carried out by a skilled engineer, the machine can now be automatically operated by the machine operator, in accordance with the manual system. In addition to reducing the direct costs of the project, or the use of the computer-controlled machine tools, it ensures uniformity of the pieces because, as long as the computer is the controller of each project piece so produced.

Due to their great complexity, computer controlled tools are often very sought after. If great care is taken in the design to safeguard an error-free operation of the machine-controlled machine for extended periods of time, if it occurs.

The anomaly, or the complexity of the machine tool, often forces specialized repair personnel to make an effort and lose a lot of time to diagnose;

due to anomaly of the machine tool. Because the time or cost involved in repairing these skilled personnel is often inaccurate and because the stoppage time of the machines often results in production delays, they are also very expensive, so it is difficult or difficult to diagnose or repair them. machine tool as fast as possible.

To facilitate rapid diagnostics of anomalies in the machine tool, I developed the diagnostic communication system described and valued in U.S. Patent No. 3882305. issued to me on May 6, 1975, which has been assigned to the carriers of the present invention. The diagnostic communications system described in my diploma comprises modems (modulators), that is, modulators-de-modulators, for generating a long-textured machine-readable computer-controlled program. an analysis of the operation of the long text and the computer controlled machine. In operation, a connection between the long text and the computer controlled machine and the centrally installed diagnostic computer is restored by a voice communication between the machine operator and the machine operator. Subsequently, both the Hypnosis Analyst-

Af digitally kodikopoiimenai pliroforiai constituted by instructions transmitted in the diagnostic calcd tissue to the controlled by the accounting istin ergaleiomichanin and from characteristics of the power tool, detected during the period of operation of the machine unto this in response to previously received instructions from the central diagnostic processing means, Haitian Instructions for are transmitted from the machine to the diagnostic computer.

One of the disadvantages of the communications diagnostic system in my patent number 3882305 is that an Analyst must be present at the diagnostic computing position to facilitate remote control of the machine. diagnostic calculus; If there was a possible or automatic repair of the diagnostic computer communication after the long text and the computer controlled machine, it responded to a test command; " presented during the operation of the machine, It would be impossible to avoid either the Analyst needing the position of a diagnostic calculator, or this Analyst would be unlikely to be free to perform other tasks, so the costs would be substantial.

In addition to its memory blocks 20a to 20d, the processor 16 is coupled to a disk drive system 22 and a magnetic tape drive system 24 to an assisted I / O interface 26.

Disk actuator system 22 serves as the primary means for storing information causally related to each CNC machining center, which can interfere with the computer's diagnostic system for diagnostic analysis. Information on disc 22, which relates to each CNC machining center, includes indications of machine type as well as parameters of engine design limits and indications of machine operating characteristics obtained in the past, any items listed in sequence numbers at the CNC machining center. Magnetic tape drive system 24 serves as a buffer for disk drive system 22 and may also be used for entry-. earth initially, and thereafter updated, the stored pro / letters in each of the memory blocks 20a, 20b,.

20c, 20d. Although the computer-based diagnostic system 10 is designed for non-regulated operation, it may be advantageous to configure the diagnostic system via a computer-based computer 10 with one or more output-output devices 28, e.g., a CR device. a high-speed printer or a keyboard printer, all of which will be able to be connected via the I / O interface 26 to the processor 16. I / O devices no. 28 enable an analyzer, if present, to monitor diagnostic computer 15 and the operation of the CNC machining center 14.

Each of the numerically controlled machining centers, which is interfered with by the computer diagnostic system, takes the form of a 14 numerically controlled machining center, including a numerically controlled computer under a machine tool control system 30. If the machine tool control system 30 can take the form of any well-known machine tool control system, in today's preferred embodiment, the machine tool control system 30 is comprised of a control system and contains a processor 32, which is coupled through an intermediate I / O device No.34 to the machine tool 28. The processor 32 is coupled to four memory blocks 36a to 36d, each storing a permanent consumer receiver, a temporary (diagnostic) program, a communication program, and a machine program, respectively. : V * Input-Output Interface (I / O) 34 also conjugates the processor to 3% each. six elements: the data display unit 42, the movie reader 44. and the control manuals 46. '0 The tape reader 44 serves as the means through which each of the four stored programs in the memory blocks 36a to 36d, respectively, enters first and then updates. Radial output elements produced during the operation of the machine are shown on the display unit 42, or which typically consists of a cathode ray tube or a plasma-type display, on a machine tool operator. * In response to the data shown on display unit 42, commands coming from the controller may be accessed by the processor 32 via the manual controls 46, so that the manual controllers 32 initiate or intermediate process with the diagnostic communications system 10.

To repair a communication link between the CNC drummer 14 and the telecommunications diagnostic system 10, via a communications channel 48, e.g., via a long-distance telephone line or through one _;microwave channel connected at each end following a local telephone connection in response. to a test command derived from manual controls 46, an automatic selector 50 and a communications modem 52 are each coupled to one end of each other 48 No. 26 of the Diagnostic Calculator (5^X \ » ' - - \

In response to an embodiment of the processor 32, as it is transmitted to the automatic selector via the intermediate I / O device 34, the selector 50 automatically reaches 40 automatically through the Modem 54 following the transmission of a unique identification code (the automatic answering machine modem telephone number 54) through the communications channel 48. The automatic answering modem 54 automatically responds to the identification code which is transmitted by the automatic selector 50 and, after transmitting the identifying code, the computer automatically responds to the incoming code 15 by inserting it automatically. these between the diagnostic communications system 10 and the CNC of the machine tool 14.

The diagnostic communications system of the present invention operates in the following manner: It is first assumed that the processor 32 of the machine control system 14 executes the machine operating program at the beginning, whichever is or is not stored. of the machine tool 28. If a malfunction occurs during the execution of the machine operating program, either on the machine or on the control system of this machine, the machine operator will cause the controller to enter the control unit 46
