Definitions

  • the present invention relates to machine control panels providing selectively operable switches and indicators associated with a machine to be controlled.
  • Machine control panels having a fixed display of c system controlled by the panel are well-known in the art, e.g., the control panel shown in U.S. Patent No. 3,187,321. While such prior art panels are useful to enable an operator to visualize the control effects of the switches on the panel, they are severly limited in their correlation to a particular system whereby each control panel is custom made for a particular application. Thus, they are not interchangeable among different systems and are inherently incapable of providing a maximum utility from the panel components. In order to increase the adaptability of such control panels, later developments included the use of overlays providing different sets of indicia as shown in U.S. Patent No. 4,158,130 and correlated auxiliary displays with switch functions thereon as shown in U.S. Patent No.
  • An object of the oresent invention is to provide an improved machine control panel.
  • a control panel which would be economical to manufacture and purchase in small numbers must be adaptable throughout its operating life to whatever machine or system is to be controlled thereby.
  • Such a universal and adaptable control panel would yield a maximum return on the investment therein while mimmizing production cost, service cost, parts inventory and operator training time. Accordingly, it is desirable to provide a machine control oanel which is universal in its applications and which offers a maximum utilization and adaptability of its components in a simple and low cost structure.
  • the machine control panel has a matrix array of a plurality of switches and light emitting indicators, a support means for supporting the switches and indicators in a substantially coplanar relationship, an aperture layer overlvinn the support means and the switches and indicators with light transmissive apertures therein aligned with resoective ones of the indicators, aperture covers on the aperture layer for selectively blocking light transmission through the apertures and label means located on the aperture layer with light transmissive apertures being aligned with preselected ones of the apertures in the aperture layer.
  • FIG. 1 there is shown a machine control system embodying an example of the present invention for controlling a machine 2, e.g., a machine having selectively operable controls thereon.
  • a matrix of a plurality of light emitting indicators, e.g., light emitting diodes (LED's), and selectively operable switches arranged as a control panel 4 is used to provide an operator interface for producing control signals for the machine to be controlled and to provide a visible display of valid switch actuations and controlled machine operations.
  • LED's light emitting diodes
  • the machine control panel 4 is arranged as a full matrix of pressure sensitive switches and LED's residing in a protective and supportive enclosure and having a flexible cover over the matrix with light transmissive, e.g., transparent, apertures aligned with selected or valid ones of the LED's in the LED and switch array 4.
  • light transmissive e.g., transparent
  • a configurable control 6 is interposed between the switch matrix 4 and the machine to be controlled 2 to accept switch actuation signals from valid switches on the switch array 4 and to provide energizing signals for valid LED's, e.g., LED's associated with actuated valid switches and LED's signaling machine operations, while transferring the control signal from the actuated valid switch to the machine to be controlled 2 to produce a corresponding control operation.
  • the configuration control 6 is also effective to ignore actuation signals from invalid switches 10 as determined in a specific application of the switch and indicator matrix 4 and to prohibit energization of undesired LED's, e.g., those associated with invalid switches.
  • FIG 2 there is shown a pictorial illustration of a control panel suitable for use as the control panel 4 shown in Figure 1.
  • a plurality of selectively actuable pressure sensitive switches 10 and LED indicators 12 are arranged in a matrix in a first support layer 14.
  • the switches and LED's 10, 12 and layer 14 may be any suitable devices capable of providing a fixed matrix of pressure sensitive switches and indicators in a substantially coplanar array, such devices being well-known in the art.
  • An adjacent second layer 16 of a flexible material capable of transferring switch actuation pressure to the switches 10 provides a matrix of light transmissive apertures 18 surrounded by an opaque coating 20.
  • the second layer 16 may be generally of a transparent material with the apertures 18 being gaps in the opaque coating 20.
  • the apertures in the second layer 16 are aligned with the LED's 12 in the first layer 14. To correlate the second layer 16 to a specific application of the control panel 4, selected ones of the apertures 18 are retained in a light transmissive state while the other unneeded apertures in the aperture matrix 15 are selectively covered by opaque covers 19.
  • Labels 22 with indicator apertures 24 are placed on the aperture array 16 with the indicator apertures ' 24 aligned with the unblocked ones of the apertures 18 whereby light emissions from energized LED's would be transmitted through the aperture 24 in the label 22 and the aperture 18 in the aperture layer 16.
  • Other labels 25 showing unilluminated switches and system interconnectors, etc. are also selectively placed on the aperture array 16.
  • a transparent third layer 26 may be used to protect the labels 22 and the other display elements 25 appropriately placed on the aperture array to form a desired machine control panel.
  • the third layer 25 is also made cf a flexible material capable of transmitting a switch actuation motion to the switches 10 in the first layer 14.
  • a suitable enclosure not shown, may be provided for housing the machine control panel 4 while enabling electrical connections to be made thereto.
  • the housing may advantageously include door for limiting access to the machine control panel 4 while increasing the protection of the machine control panel 4 from the surrounding environment.
  • FIG 3 there is shown a block diagram for the configuraole control 6 shown in the system illustrated in Figure 1.
  • the control 6 is effective to accept switch actuation inputs from valid ones of the switches in the switch and LED array 4 and to energize corresponding ones of the LED's, e.g., to provide an indication of the switch actuation of the valid ones of the switches 10. Additionally, the control 6 is effective to energize additional ones of the LED's 12 to provide a further indication of system operation.
  • the energized LED's are arranged beneath unblocked ones of the apertures 18.
  • the presence of a complete matrix of switches 10 and LED's 12 in the first layer 14 is configured into a desired switch and LED array for a specific control panel application by the configurable control 6 which accepts inputs from desired ones of the switches 10 and ignores switch actuations which are not a part of the desired switch array.
  • the configurable control 6 energizes LED's associated with respective valid ones of the switches 10 and other desired LED's to indicate machine operation and does not provide an energization of undesired ones of the LED s 12, e.g., those associated with the invalid ones of the switches 10.
  • the presence of a complete matrix of a plurality of switches and LED's in the first layer 14 provides the maximum capability for organizing the machine control panel 4 to enhance the versatility of the machine control panel whereby the switches 10 and LED's 12 may be arranged to function in a desired control panel configuration within the matrix capabilities.
  • the control panel 4 is universal in its applicability and can be easily adapted for a multitude of applications by a simple rearrangement of opaque covers 19 and labels 22, 25 to correlate it with a specific macnine or system to be controlled.
  • the switches 10 are shown as a switch matrix 10 and the LED's 12 are shown as an LED matrix 12.
  • the selectively configurable control 6 is arranged to provide a control function for the switches 10 in a procedure which is similar though separate from that provided for the LED's 12.
  • the switch matrix 10 is connected by input lines 25 and output lines 27 while the LED matrix 12 is only connected by output lines or energizing lines 28 to an input/output (I/O) circuit 30.
  • the I/O circuit 30 is divided into separate sections for handling the switch matrix 10 and LED matrix 12.
  • the I/O circuit 30 can include a multiplexer for scanning tne rows and columns of the switch matrix 10 to detect and identify an actuated one of the switches 10.
  • a digital computer 32 which may be in the form of a microprocessor, a read-only-memory (ROM) 34 for storing computer operating programs, a random access memory (RAM) 36 for storing a table of valid switch locations, and a serial communication circuit 38 are connected to data bus 40 which is also connected to the I/0 circuit 30.
  • ROM read-only-memory
  • RAM random access memory
  • serial communication circuit 38 provides a communication interface with a two wire cable 42 interconnecting the serial communication circuit 38 with a remote serial communication circuit 44.
  • the remote serial communication circuit 44 may be part of a central controller which may also include a ROM 46, a RAM 48, a digital computer 50, a CRT and keyboard interface 52 connected to a CRT display 54 by signal cable 55, and a signal cable 56 to a keyboard 58.
  • a databus 60 is arranged to interconnect the ROM 46, the RAM 48, the digital computer 50 and tne interface 52 with the serial communication circuit 44 and with a digital input circuit 62, which is connected to a digital input terminal 63, and a digital output 64, which is connected to a digital output terminal 65.
  • the detailed operation of all of these data storing, transmitting and processing elements is conventional and well-known in the art.
  • the keyboard 58 in the central controller can be arranged to enable an operator to provide the information for selectively configuring the control panel 4 by storing in the RAM 48 a table of the valid switches and LED's in a specific control panel application. For example, in a control panel having a matrix of 32 switches and 64 LED's, the information is stored on the individual switches and LED's as 8 bit entries each representing a valid switch location and LED location in a row and column format. This table is periodically read out from the RAM 48 via a stored program in the ROM 46, and is serially communicated over the connecting link 42 to the serial communication circuit 38.
  • the selective actuation of a switch in tne switch matrix 10 is detected, identified and stored in a table in the RAM 36 under the control of a program stored in the ROM 34.
  • the actuated switch data is periodically compared with the table of valid switch data sent from the central controller to determine whether or not the actuated switch is a valid switch.
  • the transmission of the switch and LED table data and the comparison with the switch actuation data is, of course, performed at a very high electronic speed in comparison to the slow mechanical switch actuation operation.
  • the entire switch validity table is compared at least once during the time that a switch is mechanically actuated by an operator.
  • the digital computer 32 in the contrcl panel 4 after comparing the switch actuation information, stores a table of switch actuation data in the form of digital words, e.g., four words or oytes of eight bits each for thirty two switches. Upon a request from the central controller, the computer 32 sends the stored digital words back to the central controller to identify the switch status.
  • the digital computer 50 in the central controller accordingly, produces a control word for application to the digital output 64 to provide an output signal on the output terminal 65 for operating the machine to be controlled 2 in response to the actuation of a valid switch.
  • Digital inputs on the input terminal 63 which may originate at the machine to be controlled 2 are supplied to the central controller for utilization in accordance with the stored program in the ROM 46.
  • the computer controller 50 may also produce digital outputs on the digital output 64 to directly affect the machine or system being controlled by the control panel 4.
