Description

SYSTEM AND METHOD OF PRESS PRODUCTION MONITORING BACKGROUND OF THE INVENTION 1. Field of the Invention. The present invention relates to a press monitoring system and, more particularly, to a press monitoring system that can transmit and receive commands from a remote site communication network. 2. Description of the related art. At present, press manufacturers have a need to understand how their machines, for example punching and stretching presses, and the like, operate in a production environment. Normally, there is no specialized test press dedicated exclusively to research and development, while the press or machine tool manufacturers typically build a machine and then sell and ship it immediately. Said commercial practices do not allow the acquisition of data related to the long-term operation of the machines. Additionally, periodic visits by the machine manufacturer are not sufficient to obtain information on how it is operating daily. In addition, it would be beneficial to have detailed information on how a prototype of the machine is operating in the field. There is interest and the need to use more information about the use of the machine or the press by the customer or the manufacturer for other reasons.

Sometimes excessive warranty repair should be made for the misuse of the machines. It would be beneficial to monitor the misuse of the machine, and additionally identify problems before they lead to an effect on production efficiency. In addition, there is a need for information on what new features and systems of the machine are being used, for example, how often a particular option is turned on or off or when it is operated with the machine in general, or both. There is a need to provide additional service to customers, for example, by identifying particular uses of the machine and identifying conditions when particular elements may be degraded without the customer knowing that the item is about to fail. In a perfect world, issues such as bearing failure, valves not working properly, or individual systems operating too hot or too cold, too high or too low would be monitored. By having more information, it would be possible to send service personnel to identify the problem and reduce the production downtime by immediately resolving the problems in a controlled manner. In addition, preventive maintenance could be monitored and controlled. What is required in the technique is a machine monitoring system, for example a press, which constantly monitors the press during production, particularly would monitor the press twenty-four hours a day, seven days a week, and transmit the data to a remote site. SUMMARY OF THE INVENTION The present invention provides a system and method of monitoring a machine, for example, a punch press or stretching during production, twenty-four hours a day, seven days a week. Additionally, monitoring can be done at a remote site through a communications network, such as a telephone system or the Internet. The new system monitors functions and parameters of the press separate from the actual controls of the press, therefore, the system can be adapted to presses of many different manufacturers. The present invention incorporates a philosophy of strictly monitoring the press and controlling the data obtained from it, in such a way that there is no link with the operation of the machine, either mechanically or electrically. Therefore, the current system does not disturb the disposition of the machine or its control. One advantage of the current system is that the data collected from the press during production can be sent to a remote site for analysis. The system also incorporates the functionality that the remote site can reconfigure both the hardware and the monitoring device software, located adjacent to the press or machine, through the communication network. Additionally, the remote site is able to reconfigure the monitor to modify the measurement criteria and also modify the particular limits and programmed variables. Additionally, the system is capable of capturing and controlling any and all specimen failures (that is, a measurement out of range from a previously determined limit condition), hardware failures and software failures. Another advantage of the present invention is that the local monitoring system can place a signal to the service personnel of the machine on the site via fax, personal pager, or other mobile or off-site communication mechanism. It is anticipated that particular personal locators, even vibrators, may be activated by the signal sent from the local monitoring platform. Another advantage of the present invention is that it incorporates several monitoring criteria, which are selectable by the user in different input-output cards (I / O cards). Some of the sensors used are connected to the monitoring system box and are attached to particular portions of the press. These I / O cards condition the signal from the sensors to create a signal in a format that is acceptable for recording in the processor of the computer of the invention. Another advantage of the present invention is that it allows to use variable data recording systems, depending on an order of the users. This includes the ability to reconfigure the data record depending on particular time periods desired, selectable alarms, record monitoring only when requested, or several different parameters as shown in the software configuration file. Another advantage of the present invention is that it uses a communication network between the local monitoring system and the remote unit. The communication system may include a telecommunications network, for example, a telephone line, cell phone, internet access, ATM transfer, and other protocols for transmitting data to and from the remote site. In addition, and more simply, a serial cable can be connected between the local site and remote site, or other protocols, such as local area networks, or wide area networks, known in the art for transferring data to through this. The invention, in one of its forms, provides an electronic processor, together with a mechanism for accessing a communication network connected to the processor. A sensor for measuring a desired amount of the press is connected to the electronic processor and is capable of sending a signal to it. An electronic processor is adapted to send a signal or through the communication network corresponding to the measured quality. The remote unit is connected to the communication network, adapted to the remote unit to accept the signal coming from the electronic processor and to visualize the measured quality of the press, by means of which the press can be remotely monitored during the production of one of the the presses. In one form of the invention, the electronic processor includes memory mechanisms for storing the value of the signals received from the sensor for a period greater than 24 hours. The invention, in another form thereof, comprises a method of monitoring a press during production, the method includes the steps of providing an electronic processor and a sensor to respectively acquire data and measure a desired quality of a press; provide access to a communication network, connected to the remote unit to display an indication of the measured quality of the press. The method also includes the steps of measuring the desired quality of the press, then operating the electronic processor to send a signal through the communication network representative of the measured quality of the press, whereby the remote unit receives the signal .

Additionally, the electronic processor 20 may include programmable logic controllers configured of hardware or software (PLC's) and numerous different types of computer equipment and electronic processing. The sensor 12 is connected to the local unit 16 via a signal line 22 which passes the signals created by the sensor 12 to a subsystem or input / output board 24. The input / output board 24 may comprise a system of signal conditioning or amplification system to use the sensor output received on line 22 and modify that signal to a format useful for processing by the processor 20. For example, sensor 12 turns out to be a temperature sensor, the line output step 22 may comprise a local DC signal. The 1/0 board can then be, for example, a 32-channel multiplexer SCXI-1001 from National Instruments to condition this received CD-level voltage signal to a digital signal for use by the processor 20. Communications between the boards 1/024 and processor 24 can be organized, for example, by a National Instruments SCXI-1001 main unit, which acts as a central communication between one or more I / O boards 24 and a typical ISA bus used with processor 20. The local unit 16 further includes a clock or timer 26 to create time signals for both I / O boards 24, together with the processor 20. The processor is functionally connected to a memory mechanism, for example a memory unit 28. memory unit 28 may be one of several types of memory systems conventionally available today or in the future, for example a particular RAM memory, hard disk memory, tape, CD ROM act ivo, or another memory unit in which signals can be stored and retrieved. Additionally, the processor 20 further has a comparator mechanism, for example a comparator circuit 30, either connected to or functionally arranged within the electronic processor 20. The comparator 30 is used to make comparisons between two values or signals and generate an output signal. based on the comparison. The local unit 16 further includes a mechanism for accessing a communication network 32, for example, a modem 34. Although in the preferred embodiment of the invention, the mechanism for accessing the communication network 32 is a modem functionally connected to the processor 20, other types of mechanisms can be used to access a communication network 32, depending on the communication network 32. Various types of communication networks 32 can be used, for example, a specialized telephone line. a telephone call line, a cellular telephone system, wireless network system, internet access system, ATM transfer system, together with other types of protocols for transmitting data to and from the remote site 18. Depending on the type of communication network 32 used, that may modify the type or mechanism to access the communication network 32. In addition, the communication network 32 can be that of a local area network, wide area network, or simply a serial cable, or all of these. The mechanism for accessing the communication network 34 may, therefore, be a simple serial bus, or another type of computer communication card for communicating with the communication network 32. As shown in Figure 2, the communication network 32 is connected to the remote unit 18. The remote unit 18 is adapted to accept a signal communicated by the electronic processor 20 through the communication network 32 and to display the measured quality of the press measured by the sensor 12, such that the press 14 can be monitored remotely during a production run of the press 14. As shown in Figure 2, the remote unit 18 includes a processor 40 connected to a display mechanism 42. remote unit may include a printer 44, together with some kind of alternate indicator 46. The alternate indicator may be a warning light, siren, bell, or any other type of indicator to indicate which a signal has been received from the local unit 16. The present invention of remote unit 18 may comprise a personal computer, for example a programmable computer compatible with IBM 46 or PENTIUM brand. Additionally, the remote unit 18 can be a fax machine in which the signal sent by the processor 20 through the communication network 32 is accepted by the fax device of the remote unit 18 and printed using its printer 44. In another form, the remote unit 18 may be a personal locator in which the signal generated by the processor 20 can be displayed in the electronic personal locator 18 in the form of an LCD or LED 42 to indicate to the service personnel the reading of the sensor particular 12 created. Additionally, the information communicated by the processor 20 to the remote unit 18 can include the location of the press 14, along with other data regarding the conditions that caused the processor 20 to send the signal to the communication network 32. In the In the case where the remote unit is a personal locator, additionally, there may be a vibrator 48 coupled thereto to indicate that a signal has been received from the local unit 16. In most industrial applications the service personnel of the area do not would be able to hear type of audio signal generated by a remote unit 18, but would be able to sense the activation of the unit 48. As shown in Figure 1, the system 10 may include several qualities or monitoring functions that can be selected . For each function shown, a different I / O card 24 is normally used to condition the signal sent by a particular related sensor 12. Among the monitoring functions are: 1. Production speed - this function would include a sensor 12, for example a travel counter to count the number of press cycles per day or according to a certain period of time. System 10 could also count the number of pieces. The system could also use a time measurement and calculate the speed of the press. In a preferred embodiment, an infrared sensor applied to the portion of the press to enable counting of each stroke of the press. 2. Compression / traction load factors - this function uses a coupled accelerometer and the 1/0 functions on the board 24 to measure the acceleration signal to obtain a compressive load and peak traction measurement. That information would help monitor the press at low speeds. 3. Monitoring of vibration severity - acceleration signals can be used to determine the severity of the vibration of the press application as known in the art. 4. Monitoring of critical discrete component vibration - in this measurement capacity, the user of the press can apply an accelerometer to a portion of the press in which it is desired to collect data; 5. Critical temperature monitor - this function is used to monitor: a. bearing areas; b. oil temperatures; c. the temperature of the plate in comparison with that of the car; and d. temperature stability of the press -temperature through the press with time and use. Temperature measurements are useful for evaluating the production condition of the press. If the temperatures go outside the limits, the operation of the press can be stopped to investigate that condition that goes beyond the limits. 6. Critical pressure monitoring - this function would employ a pressure transducer, or similar, to generate a pressure signal for the oil or other pressures, or all of these that must be within certain ranges. 7. Motor load monitoring - this function would measure the current stretch of the press motor or can be applied to any other motor used, ie, press feed motor and auxiliary equipment motor. If the current stretch increases, for example, compared to historical levels in the machine, the engine is running more for some reason and that event can be investigated. 8. Dynamic closing height control - in this function, the system 10 would detect the change of the closing height with a non-contact sensor 12 for example, an inductive type zone. The height changes of closure can then be investigated. The ability to maintain a constant closing height during press operation creates more accurate work pieces. 9. Parallelism Monitoring - This function, similar to 8, uses two or more preferably inductive probes to determine the parallelism of the press studs, the connecting rods, and between the carriage and the die of the press, etc. 10. Tilt Moment Monitoring - This function would monitor the load on one side of the press compared to another. A voltage meter would be the preferred sensor used for this function. 11. Piston charge monitoring - This function would measure the total load of the press or some fraction of it. 12. Monitoring of the thermal control system - These functions would measure the effect and efficiency of the press heaters and coolers and possibly on the workpieces of the press. 13. Monitoring the use of the percentage of the press - This function would enable the monitoring of the use and effective operation of the press. A limit switch or other sensor that would be used to determine that the press was being used. By comparing, or more exactly, dividing, the time spent or the pieces produced, or both, a percentage of the use number could be calculated. 14. Measurement of characteristics - This function would measure the characteristics of the prototypes in the prototype machine and determine how often or when the characteristic is used. The sensor 12 used could be of almost any type depending on the characteristic of the press to be monitored. The current system 10 is preferably promed through a C ++ object oriented language and works on an IBM compatible personal computer, such as a 486 microprocessor or PENTIUM. Other types of electronic processors and computer languages can be used in an equivalent way. Normal proming and electronic organizational procedures would enable someone with normal skill in the art to create software to communicate the hardware used. In the preferred embodiment of the invention, all limits on measurement, device control, routing, alarm limits, preferably any constant or variable are encoded by the software, so that the system can be used with different hardware and 1/0 cards, for example. In one example, a temperature sensor with a CD level output is connected to a 32-channel multiplexer card SCXI-1001 from National Instruments, to translate the sensor output on line 22 to a numeric sign. A National Instruments SCXI-1001 Main Unit (connected to the previous card and other I / O cards 24) is used to condition the output signals of the I / O cards 24 to the ISA bus of the processor 20. As would be clear to someone skilled in the art, other I / O cards, central communication cards, structures and bus processors can be used in an equivalent manner. The selection of the programming language and operating system would also be selectable for the user depending on the total desired functionality. Figure 3 shows an example of a typical possible set of commands and lists the goal or function, to allow someone skilled in object-oriented programming to build the current system. Subsequently a list of a sample configuration file for the system 10 is shown in this application, which presents several variables with programmable coding, therefore configurable in software. Said software configuration capability of these indicated system variables allow commands or signals from the remote unit to reconfigure the local unit 16 depending on the wishes or requirements of the user now or in the future. In the preferred embodiment of the invention, a personal computer using a Windows 95 operating system allows organized control objects to be used. In addition, the software created for use in a remote unit 18 could analyze the measurement signals sent through the communication network 32 and conclusions could be drawn from the state of the press 12. Figure 4 presents a design of a control program of object-oriented software for use with the present invention. Depending on the particular functions selected by the design for monitoring, different data acquisition objects may be created, as is known in the art. Figure 4 shows that almost any type of data, from the protocol and IEEE format, limit switch counter, multimedia, DC voltage, AC voltage, waveforms, temperature, voltage and others can be captured in the local unit. for storage in the memory 28 or transmission through the communication network 32. Depending on the type and amount of data that will be sent, the software design may use different data transmission protocols known in the art. Figure 5 shows an example of an input / output object-oriented software hierarchy that would allow a user to configure the system 10 using the software configuration file (an example of which is provided below). Depending on whether the user designer wants to store data in memory (Cio_file) or transmit it to the modem (Cio_Modem), a device that complies with the IEEE protocol (Cio_IEEE) or to and through a Windows 95 DDE application, the functionality is possible. In addition, as shown, it is also possible to record data on a screen and a printer. Figures 6 and 7 present a programmed object found in the software that controls the processor 20 of a fault filter. This object, using normal constructions to object-oriented programming, would allow to catch the conditions of failure and to register (saving in the memory) or transmission (through the communication network 32) of the conditions for the current and later study and use. The system and method further include the functions described as advantages mentioned above. By using the object-oriented design and the local software configuration file presented below, the local unit 16 can sometimes be reconfigured by the use of signals from the remote unit 18. The system 10 then has an electronic processor that includes a mechanism to verify failures and thus create a status code. As shown in the software configuration file, and known in the art, therefore, the processor has several reconfigurable settings previously determined. The processor 20 can access the communication network 32 and send a signal to the remote unit 18 when the status code is outside a predetermined limit. At that time, or in any other, the remote unit 18 is adapted to communicate through the communication network 32 and alter the previously determined settings related to the electronic processor 20 and the system 10. The reconfiguration can eliminate the failure condition Found The reconfiguration by the remote unit 18 can also modify the data acquisition characteristics of the system 10 by turning on or off certain sensors, 1/0 boards, or other units. Although this invention is described with a preferred design, it may be further modified within the spirit and scope of this presentation. Therefore, this application is intended to cover any variation, use or adaptation of the invention using its general principles. Furthermore, this application is intended to cover any element that moves away from the current presentation that falls within the practice known or accustomed in the art to which this invention relates and which falls within the limits of the appended claims.
