Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display system having multiple character stations, in which characters are created by applying a set of binary signals at each row or other character station. Concerning a system for displaying alphanumeric messages, more specifically, a system for displaying alphanumeric messages, in which each display message is either wholly or partially derived from the memory with which it is associated.
fragments and messages emitted by a detector or other device that in part represent real-time conditions and provide real-time output;
Concerning a display system that can be either a fragment or a force-1 message.

The multi-character station display device used in the system of the present invention is such that each character station is switchable between visible and invisible states, and each character station can be switched between visible and invisible states to display any of a set of alphanumeric characters by visibly different combinations of segments. It may be any one of many different types of devices having multiple segments designed to perform a single generation. Examples of such devices include Nixie tube displays, light emitting diode (LED) displays, liquid crystal (LCD) displays, and vacuum fluorescent tube displays.

It is known to multiplex input signals from character stations in order to accommodate a reasonably large number of character stations in a display device. In such a multiplexing scheme, time is divided into repeating time frames each having a number of time slots equal to 7 times the number of character stations,
Each time slot is assigned to a respective one of the display stations. During each time frame, sets of binary signals representing the characters to be displayed at the various display stations are applied one after the other to the character bus, and the signals designated for a particular character station are applied during that station's tie L slot. given to the bus. The character stations are then synchronously enabled to receive the set of binary signals assigned to them from the carrier bus during those time slots. In the past, the source of the binary signals applied to the character bus to produce the displayed messages was generally a memory or other message storage device, so that the displayed messages were It is limited to messages that are somehow artificially crafted prior to the display of real-time variables such as time of day, pressure, temperature, flow rate, RPM, or the like (4) that exist at any point in an industrial process. It is well known to use multi-character display devices to display instantaneous values, but in such cases the display device is usually permanently associated with a single variable, or if many variables It does not include any identifying or informational characters other than the characters representing the instantaneous value of the selected variable, even if it is possible to switch to any one of them.

A single multi-character display device for selectively displaying either a message originating solely from memory or a message consisting partly of stored message fragments and partly of message fragments originating from a real-time device. It is an object of the present invention to provide a display device that can be used for.

Thus, for example, the display system of the invention can be used with a self-help regulation system for industrial processes,
A full set of stored messages can then be displayed advising the operator of the status of various aspects of the process monitored and controlled in response to different conditions by the control system.

Such a message will probably give the operator a warning of the power being out of order, or bring the process back to normal or otherwise maintain proper operation, so that the operator may or may not be advised of the action to be taken on the part of the operator. At other appropriate times, the display device may show the instantaneous values of various real-time variables during the controlled process, and each displayed value may be used as a legend or other support to convey information related to it. Contains multi-character message fragments. In such applications, automatic control systems for complex processes select the messages displayed by the display device; however, the display system of the present invention can be used in a variety of different It can be used with other types of message selection devices.

Other objects and advantages of the present invention will become apparent from the following detailed description of the preferred embodiments and the drawings.

The present invention allows any one of a set of characters given at each character station to be displayed by providing a set of binary signals to the station: FJ1. The message display system includes a number of caplays, an LED display, an LCD display, etc. as a display device. Memory is associated with the display device and real time signal devices such as multiple detectors are associated with multiple real time conditions. The memory stores a number of multi-character stored message fragments, and the real-time signaling device selects real-time message fragments that respectively correspond to a respective one of the real-time conditions. The message selector selects one of the stored message fragments and one of the real-time message fragments, and the associated routing device selects the two selected message fragments, partially stored message fragments and partially real-time message fragments. and to a display device to display the complete message made with.

The invention also resides in a memory for storing one or more complete messages thereon and a message selector and routing device operable such that the complete stored messages are selected and displayed by a display device.

More particularly, the present invention provides a real-time signaling device for transmitting selected real-time message fragments in the form of one or more binary coded decimal digits and for transmitting the binary coded decimal digits in the same manner as other character outputs from memory. 2 encoded with code
A single message that serves as a code for a communication signal
Located in memory with an address.

In Figure 81, the message display of the present invention
The system basically has a multi-character display 1o and a memo IJ-1' that stores various Rona messages.
2. A real-time signaling device 14 for selection of real-time message fragments comprises a clock device 16 and a message selector 18.

The unique display device used in aspects of the invention may vary and may be, for example, an LFtD display, a Nixie tube display, an LCD display, or a vacuum fluorescent tube display.

In any case, the display device emits various segments that can be switched between illuminated and non-illuminated states, or otherwise visible and invisible states. The character display station has a plurality of character display stations each having a number of display segments or display elements configured to display or make visible different alphanumeric characters. The number of character display stations and the number of display segments in each station may be varied without departing from the invention. However, by way of example, with the illustrated display Ltfat 10 Fil 6 character display stations 20.2'0, each display station 20 is a vacuum fluorescent tube display having 19 display segments 22.22. As shown in the two display stations on the left, the 16 segments 22, 22
is made to accommodate any one generation of a relatively large set of alphanumeric characters, and three other elements (not shown) accommodate the generations of commas, apostrophes, and periods. Each display station is used to accommodate.

According to a broad aspect of the invention, each character display station 20 of the display device has a set of input terminals or equivalent, indicated at 24, having a number of bits equal to the number of display segments 22.22 at each station. 2 communication signals can be provided to the display station via it, and a set of input terminals 2
4.24 are all connected to or part of the character bus 26,
Each display station 20 also, when provided with an enable signal, connects the display segments 22 to the display station in order to cause the display segments 22 to emit light or become visible in combinations commanded by the input binary signals. Set of input terminals 2
4 has an associated enable terminal 28 for gating the then present binary signal. In the case of the illustrated true fluorescent tube display 1'0, each display segment 22 is an anode segment and the corresponding anode segments of all display stations are electrically connected together such that each display segment 22 is an anode segment. 19, which is the number of display segments in the station.
As a result, the 19 anode terminals form the character bus 26 shown. Each display station then has its own grid of terminals comprising the enable terminals 28 shown.

Memory 12 can take various forms and stores a number of messages, each given a number of character storage locations equal in number to the number of character display stations of display device ff10.

Thus, in the illustrated case, memory 12 has 16 character storage locations for each stored message. The stored message is selected by a binary message address signal applied to multi-conductor address line 60 and applied to the address terminal of memory 12. Individual character locations of the selected message are selected in sequence by character address signals provided by four conductor character address lines 62 connected to four corresponding address terminals of the memory. Therefore, the message address signal 1 (
The MS G, ADD,) selects a given message stored in memory 12, and the character address signal (CHAR, ADD-) supplied on line 32 specifies the special address of the 16 character storage locations of the selected message. Choose one. The information 1-t so stored in the character storage location so selected is transferred from the memory in the form of a 19-bit binary signal to the multiconductor output line 3.
4 and its output signal is provided to the character bus 26 through a tri-state buffer 66 when the buffer is enabled by an enable signal as described below.

The message stored in memory 12 is stored in memory 16.
All of the associated character locations of the memory contain at least one message storing information to be displayed by the display device 10, and some of the associated character locations of the memory include at least one message storing information to be displayed by the display device 10. contains at least one message that does not remember the character to be displayed by. Messages with display information in all of those 16 character storage locations are defined as "Complete Memory Messages" (compl).
Messages that have display information in all or fewer of their 16 character storage locations are called "stored message fragments".
fragments) J.

The 16 character display stations 20° 20 of the display 10 in the first '19 are numbered from 1 to 16 from left to right, and the 16 character storage locations of each of the memories stored in memory correspond thereto. They are numbered from 1 to 16. The length of the stored message fragment may vary in other embodiments, but may be 16 characters long or 10 characters long in the embodiment of FIG. More particularly, for each stored message three or more display stations of display 10 can be reserved for the display of real-time information and when such a station is reserved the corresponding character of the memory is displayed. No meaningful information is stored in the storage location. Such reservations are indicated by reservation signals appearing on lines 68 and 40 and directed by message selector 18. The ES'1l-13J signal reserves display stations 11.12 and 13 for the display of real-time data and rREs1 when appearing on line 40.
The 4-j6J signal reserves display stations 14, 15 and 16 for displaying real-time data. When both reservation signals appear simultaneously, all six display stations 11-16 are reserved for displaying real-time data.

Message selector 18 selects a message to be displayed by display device 10. This applies a binary message address signal (M S G
.

ADD, ).

The message selector also sends reservation signals to lines 68 and 40 (c and binary real-time address signals (R,,'l ADD,) to four conductor real-time address lines 42, if requested.

When the message selector addresses all stored messages in memory 12, the message selector does not issue a reservation signal to reservation signal lines 38 and 4o. When the message selector addresses a stored message fragment in memory 12, a reservation signal appears on line 68 or line 40 or both lines 38 and 4o, depending on the particular character station to be reserved, on power 5 and simultaneously on the message selector. sends a binary real-time address signal () to the real-time line 42 to select the real-time data to be provided to the reserved display station of display device 1D, as detailed below.
+ 'r, ADD-) is supplied.

Message selector 1B can be constructed in many different ways without departing from the scope of the invention. For example, it may be part of an automatic control system or monitor equipment for manufacturing, processing, chemical, or other industrial processes. Depending on another condition monitored by the control system, the control system selects a message from the memory 12 which, when displayed by the display device 10, advises the operator of the state of the monitored condition, issues a reminder, gives instructions, etc. Alternatively, the control system can also select message fragments from memory 12 that is provided with real-time data from real-time signaling device 14.

Real-time signaling device 14 includes a number of devices that provide real-time data representing the values of real-time variables or other associated real-time conditions. In FIG. 1, sixteen such real-time screens are shown at 44°44. Those real-time devices 4°
4,44 doj, or 4f'J, a clock which gives a time signal, a counter which gives a signal representing a cumulative count which varies somewhat, a pressure detector which gives a signal representing the value of the detected pressure, a detection It may be any one of a number of such detectors, such as a temperature sensor or other similar device that provides a signal representative of the measured temperature value.

The signals sent out from the devices 44.44, even if they are analog signals, are binary coded decimal signals and are connected to a real time selector and an analog to binary coded decimal converter module 46. Real-time address signal (R,
,T.ADD. ) is sent to module 46, which in response selects one of the real-time devices 44, 44 and sends its output signal to output line 48. The cuffed signal sent to output line 48 is in the form of binary coded digits, and if the signal provided by the selected real-time device 44 is in analog form, module 46 binarizes it before sending it to all lines. Convert to decimal format. Line 48 has two
It consists of 6 sets of 4 conductors that send evolved decimal digits, and the 6 that is sent by
The individual numbers are shown in FIG. 1 as Dn to D+a. The number of digits sent is determined by the selected real-time device 44 and may be 3 or 6 digits. If 3
When a number is sent, it is the number D1□'+D12 and DI3.

It appears as Ihari, , D, and Dl. If six numbers are sent, they are the numbers DI+
Appears as Dl6 from.

It is connected to a binary coded decimal system 1ifX4]dBcD digit selection module 50. Also, in response to enable signals C11 to C, .theta. supplied to module 1-50, this module selects one of the numbers D11 to D16 as appropriate and sends it to module 52. To explain in more detail, the digit D11 is sent while the enable signal C11 is present, the digit □ is sent while the CI □ is present, and the same applies to 4 below.
:ft. Module 52 in turn converts the n binary decimal digits sent thereto into a 19-bit binary signal. The latter signal is in turn sent to output line 54 and applied to character bus 26 when the associated tri-state buffer 56 is ready for use.

The clock 16 has four output terminals connected to the four conductors of the character address line 62.
It includes an oscillator 58 that drives a 6-state counter 60 such that the output of the counter continuously shifts accordingly through its 16 different states or addresses.

ADD, ) signal. Therefore, each cycle through 16 different states or addresses of the character address signal forms a time frame with 16 time slots, and between each slot there is a layered character.
The address appears on the line. The character address signal read directly at the output terminal of the counter 60 is decoded into one of the sixteen enable signals C1 to CI6 supplied to the enable terminals 28, 28 of the associated display device 10, respectively. This is a one-man powered 4 output 16 decoder 62.

The enable signal ct''-016 is of course generated in synchronization with the ordering of the character address signals, so that when the character address signal addresses memory location 1 of the selected message, the enable signal C1 is simultaneously asserted and the character display station of the display device is activated. When number 1 is enabled and the character address signal addresses memory location 2 of the selected message, enable signal C2 is simultaneously present to enable character display station number 2, and so on.

The RDRT signal is generated in the circuit 76 when I2 or UC,3 occurs simultaneously with the reservation signal RES11-13, and the enable signal c14+cIs or CI6 generates the reservation signal RES11-13.
It functions to cause circuit 76 to generate the same RDRT signal when occurring simultaneously with 14-16. When the RDRT signal occurs, it enables tri-state buffer 56 and disables tri-state buffer 36 via enabler 78.

Therefore, when the message selector 18 selects one message fragment from the memory 12 and generates the R,E811-13 signal school 1 to indicate the reservation of display station numbers 11, 1.2, and 13, the enable signal C11r is activated. Each time CI2 and CI3 appear in a time frame, tristate buffer 36 is disabled to disconnect memory 12 from character bus 26, and tristate buffer 56 instead connects module 56 to character bus 26.

0 is also conditioned to select the number D1□ by the enable signal C11, and the buffer 56 is enabled by the enable signal C11.
It will be appreciated that when enabled while 12 appears, digit selection module 50 is conditioned by enable signal C12 to select digit DI2, and so on. As a result, when a stored message fragment is selected from memory 12 by a message address signal, display stations number 1-10 display information issued from memory.
Will. If the reservation signals 1tBs 11-13 are combined with the message address signals, display station numbers 11, 12 and 16 will display real-time data coming from one of the selected real-time devices 44.44. Signals RES14-17S are messages
Display station numbers 14, 15 and 16, together with address signals, indicate the selected real-time device 44.
will display real-time data issued by the . In the absence of both reservation signals during message fragment selection, the display stations reserved separately by that signal can be used to display information from memory 12. A complete display message therefore consists of up to 10 or 13 characters issued from the memory and up to 6 or 3 corresponding characters issued from the real-time device 44.44. When all stored messages are selected from memory 12, neither reservation signal is present, thereby causing all 16 display stations of the display device to display the information available from the message during each time slot of each frame. Therefore, buffer 66 is enabled and buffer 56 is disabled.

The system shown in the figure also outputs a character address signal to the ant line 42 and an enable signal ct-CI'6,
The character address and enable signals command the synchronous K IIih through 16 states during repeated time frames in the same manner as described with respect to FIG. A message selector similar to the selector 18 in FIG. 1 is also provided in the system in FIG. 2, and outputs a message address number (MSG-ADD) to line 60, indicating that the selected message is a stored message fragment. At some point, the RE811-13 signal or the RE814-
A character display station of display device 10 must be reserved for displaying real-time characters by either or both of the H.161 languages.

The message selector also provides real-time address signals (not shown in FIG. 2) that control the selection of real-time signals applied to circuit 48.

The message storage memory is shown in more detail and is additionally added to convert the binary coded decimal digits from line 48 into a 19-bit binary form so that the message storage memory is provided in character /2 space 26. FIG. 2 differs from FIG. 1 in that it is used.

It should be noted that a "blank" character can be stored, but that "blank" character is still a "character" when that term is used in this FJA specification.

During the time slot formed by C10 and C10, the RDR,T signal is generated and the corresponding enable signals "Dl 4 +RDts and RDl" are generated.

When the RDR,T signal appears on switch 8B, the switch causes all address terminals At-A+o to be grounded in order to recall stored message number 0000000. The message stored in this message address is address terminal A. This is a decoding message for converting the number given to -A3 in binary coded decimal form to the same number in the 6-bit alphanumeric code appearing at output terminals OD and -OD5. Therefore, the special binary coded decimal number is A. The same number given to terminal -A3 appears in 6-bit alphanumeric form on output terminal ODo-OD.

The RDRT signal also opens latch 92 to prevent character address signals on line 42 from going to address terminals Ao-A. RD, during the nine time slots formed by the pull signal CI4, the signal is the number DI4.

The digits are then routed through the character bus 26 to display station number 14 of the display device by the enable signal C14 present. .

Similarly, during the time slot formed by enable signals C15 and C1, the numbers D+s and Dl6 are PR
The characters are converted from BCD to 6-bit alphanumeric form by OM, converted to 16-segment form by converter 84, and provided to character path 26 to produce their display on display station numbers 15 and 16 of the display device. Thus, ultimately display 10 will display the memory message fragments appearing on display station numbers 1-16.
It will display messages consisting of real-time message fragments appearing at stations 14, 15 and 16.

If the reservation signal R is used instead of the reservation signal RES14-16,
Even if ESi 1-13 appears together with the message address signals, the operations are performed using the reservation signals RES14-16, except that the real-time fragment of the displayed message appears on display station numbers 11.12 and 13.
