BACKGROUND OF THE INVENTION
The present invention relates to a monitor display system for a wireless communication apparatus for displaying data transmitted via a bus between communication devices on a monitor screen.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there are various types of monitoring display systems for wireless communication devices that display data transmitted / received via a communication device bus on a monitor screen. Usually, the communication method of data to be transmitted / received is determined by a protocol or the like, and the meaning of data assigned to each bit of the data to be transmitted / received is determined at any time. Therefore, the monitoring display system only displays the transmitted / received data itself on the monitor screen, and the meaning of the data allocated for each bit of the data is not displayed. For this reason, refer to the interface / specifications and documents such as ICD (Insider's Computer Dictionary) published on the Internet, and send and receive data while comparing with the monitored data. The data being read is being decrypted. The ICD is a terminology dictionary that is acquired via a communication line in order to correlate transmitted / received data and the meaning of the data, and normally cannot be written in the data displayed on the monitor screen. The contents are written.
[0003]
Such a monitoring display system is disclosed in, for example, Japanese Patent Laid-Open No. 10-78376. According to this technique, monitor items necessary for searching for the cause of a vehicle failure are associated with the failure symptom, allocated and set for each bit of the byte string, and stored in a ROM or the like in advance. As a result, by selecting the item of the symptom that best matches the failure symptom, the monitor items necessary for searching for the cause of the failure are automatically selected. Then, by referring to specifications, repair manuals, etc. recorded as documents for each selected monitor item, necessary replacement parts are determined or necessary repairs are performed.
[0004]
[Problems to be solved by the invention]
However, in the conventional monitor display system as described above, data to be transmitted / received and monitor items are only displayed on the monitor screen, and the displayed data and monitor items mean specifications, ICDs, repairs. You can't understand without referring to documents such as manuals. For this reason, the data to be transmitted and received is decoded while comparing the monitored data and monitor items with the detailed contents written in the document. However, in order to read the data displayed on the monitor screen while referring to the document, a specification sheet in which detailed contents are recorded for each data or a thick ICD printed out is brought out and displayed on the monitor screen. Since the data contents must be decoded while comparing with the data, the work efficiency becomes very poor. In addition, it is difficult to understand which bits of monitor data that are actually displayed correspond to which bits of ICD, and the written contents described in ICD and the like may be difficult, and for those who have not read the data Is difficult to read and misreads.
[0005]
The present invention has been made in view of such circumstances, and an object of the present invention is to associate data contents with each monitor-displayed data in data in which the format of communication data is assigned to each bit. An object of the present invention is to provide a monitor display system for a wireless communication apparatus that can display complicated data only from a monitor-displayed screen.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the present invention is a monitoring display system of a wireless communication device, a bit array display unit that displays received data in a plurality of bits, a name of data corresponding to each bit, A data display unit for displaying data converted corresponding to the value of each bit, the content of the data corresponding to the value of each bit, a plurality of bits displayed on the bit array display unit, and the data display And a corresponding display unit that displays the content of the data displayed on the unit in association with the connection .
[0007]
According to such a configuration, in the data in which the format of the communication data has a meaning assigned to each bit, by displaying the data contents in association with each data displayed on the monitor, only the screen displayed on the monitor is displayed. Complex data can be read.
[0008]
In the embodiment, as a data display method, in the data display method for displaying the data assigned the meaning of the data for each bit on the monitor screen, the data transmitted via the bus between the communication devices is addressed. Corresponds to the step of displaying the bit array based on the table, the step of displaying the table in which the meaning of each data is individually recorded, and the data of each bit arranged in the bit sequence and the meaning of each data recorded in the table There is also shown a data display method in which data transmitted via a bus is displayed on a monitor screen through a step of displaying a line to be attached.
[0009]
According to the data display method of the present invention, the data transmitted / received via the bus is displayed, and the meaning of the data allocated for each bit of the data is also displayed. The display method at this time is such that the received data and a portion that the data corresponding to the received data mean are connected by a line. As a result, it can be seen at a glance which bit of transmitted / received data indicates the meaning of which data. Furthermore, in order to make it easy to read the data value itself even in the middle of continuous data, the content of the description is such that it can cope with irregular assignments. For example, a thick line is drawn for each bit constituting one data, and a line is connected to a portion that means the data. As a result, the meaning of the corresponding data can be acquired by following the line from the desired bit regardless of the bit allocation. It is also possible to provide an input device that allows input from a screen similar to the monitor screen so that it can cope with arbitrarily determined data, and each user can input desired data from this input device. it can.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an example of a display screen of a monitoring display system applied to the present invention. Examples of the display screen shown in FIG. 1 are a display screen for test diagnosis in a wireless device mounted on a ship or an aircraft, or a display screen of a monitoring display system used for a ship or an aircraft using the wireless device. The contents are shown. In such a monitoring display system, it is possible to display a failure status such as whether the transmission device is faulty or whether the radio wave status during communication is bad due to the influence of noise, etc., and transmission (Tx: Transmit) and reception ( Rx: Receive) can be switched and displayed as separate pages. Further, the data content used for transmission / reception is set as hexadecimal data, and this monitoring and display system converts the data contents into binary data, thereby assigning each bit.
[0011]
Data transmitted and received by the bus is of a type managed by an address. In the example of the monitor screen 1 in FIG. 1, the data part 3 has one word fixed to binary 16 bits, and the address part 2 is added as a header before that, which is also fixed. The received data is displayed as a binary 16-bit numerical value, and specification contents such as ICD are also displayed in association with each other.
[0012]
The features of the monitor screen 1 in FIG. 1 will be described in more detail. The display items in the uppermost address section 2 are generally displayed items such as band (for example, HF (High Frequency)), monitor bus name ABCDEFG, RTNo. (RadioTelephony No .: radio telephone number). , Tx (Transmit: transmission content), SB (Synchronization Bit), WBNo. (Wide Band: wideband No.), and the like are displayed. An example of this monitor screen is the case of Tx (transmission), but in the case of reception, the item of Tx changes to Rx (Receive: received content).
[0013]
In the display item of the data section 3 below it, the monitored received data is arranged for each bit. In this case, in order to make the data easy to see, the hexadecimal display of the received data is converted into a binary display and arranged side by side so that it can be easily read. In the example shown in the figure, under the hexadecimal data “0000”, the byte sequence of the binary data is arranged in 16-bit arrangements every 4 bits. That is, the data content used for transmission / reception is set as hexadecimal data, and is converted into binary data by the monitoring display system, and then assigned to each bit. Furthermore, in binary display, the data arranged for each bit may be one data composed of one bit, and one data may be composed of two bits or three bits. The data length is indicated by a single thick line. Therefore, as shown in the figure, the data composed of 3 bits is displayed with a bold line having a length of 3 bits, and the data composed of 2 bits is displayed with a thick line having a length of 2 bits. The data constituted by is displayed with a thick line having a length of 1 bit.
[0014]
In addition, on the right side of the screen, the data names and specifications of each data in the running status of a ship or an aircraft are displayed as a table 4. Such a table 4 corresponds to an ICD for associating bit-by-bit data with specification contents (so-called specifications) indicating the meaning of the data. Therefore, as shown in FIG. 1, the received data for each bit of the binary display of the data portion 3 and the meaning of the data corresponding to the received data displayed in the table 4 are connected by a line. As a result, it can be understood at a glance which bit of the received data indicates the meaning of which data. The table 4 displays “data name (title)”, “data”, and “content (spec)” of the received data. That is, the table 4 displays the detailed contents of data that has been conventionally displayed on the ICD or the like. The item “data” in the table 4 can be displayed by converting received data according to specifications.
[0015]
By displaying the monitor screen 1 in this way, it can be seen that 3 bits from the left of the binary display data of the data part 3 are displaying “radio mode” in the “data name” of the table 4. . Also, what is represented when the 3 bits of the data is “000” is the “content (spec)” part on the far right side of the table 4 without referring to the ICD as in the prior art. It can be seen that “T / R” (Transmit / Receive: transmission / reception) is indicated. Similarly, when 3 bits from the left are “001”, “T / R + G” (transmission), “010” is “DATA” (reception), and “011” is “DATA + G” (transmission / reception switching). ), “111” indicates the “initial state”.
[0016]
The 4th, 5th and 6th bits from the left of the binary display data in the data section 3 represent 1 data by 1 bit, and indicate data contents connected to the table 4 by lines. Further, the meanings of “1” and “0” in the binary data are also shown in the “content (spec)” item of Table 4. Similarly, the 7th and 8th bits from the left of the binary display data of the data part 3 represent 1 data with 2 bits, and the data connected to the table 4 with “data name”, “data”, “content ( Spec) ”. Hereinafter, in the same manner, regarding the data for each bit of the binary display data in the data section 3, the meaning of each data may be read from the position connected by the line of the table 4. Note that 3 bits from the right end of the binary data in the data portion 3 indicate the unused state of the data, and each item column of the table 4 is blank.
[0017]
Next, each part in the display screen of the monitoring display system shown in FIG. 1 will be described in detail. FIG. 2 is a detailed drawing of the data section 3 at the upper left of the display screen shown in FIG. In FIG. 2, the data portion of received data displays word data in hexadecimal and binary. The upper part shows the word data in hexadecimal display, the middle white box shows the word data in binary display, and the binary display shows one bit in one box. In addition, 4 bits of binary display are included for every 1 bit of hexadecimal display. Furthermore, bit groups for each data are collected with a thick line at the bottom. Therefore, each bold line represents the meaning of each data. In the example of the figure, 3 bits from the left of the binary data are collected by a thick line, and the content of one data is shown. Further, since the fourth bit from the left is a thick line for one bit, one bit indicates the contents of one data. Similarly, one data is grouped for each bit grouped in bold lines. Further, 3 bits from the right end are represented as a data unused area by a box of a color different from the color of the thick line.
[0018]
FIG. 3 is a detailed drawing showing the data names and specifications of each data in the table 4 on the right side of the display screen shown in FIG. In the table of FIG. 3, in order from the right side of the screen, “data name” indicating the data name described in the ICD, “data” indicating the data name, and “content (spec)” indicating the meaning of the data described in the ICD. Each is displayed. For each data item, the meaning of one data is shown in one horizontal row of “data name”, “data”, and “content”, and each data item is binary-displayed as shown in FIG. The corresponding bit data is connected with a line and displayed.
[0019]
At this time, the “data name” column and the “content” column are displayed in the table of FIG. 3 based on the recorded content of the ICD. In the “data” column, received data is converted and displayed in accordance with the contents described in the ICD. For example, when the “data name” in the table is “equipment state 2”, when the bit data in binary display in the “content” column is “0”, “GO” is displayed in the “data” column, When “1”, “subsystem failure” is displayed. When one data is displayed with 2 bits as in the case of “data name” “equipment test”, as shown in the “content” column, when “00”, “test result invalid”, “ “01” is displayed in the “Data” column, such as “Testing”, “10”, “Test completed (result valid)”, and so on. Note that unused data items are dark gray and blank.
[0020]
In addition, the present invention provides an input device capable of inputting from a screen similar to the display screen of the monitoring display system shown in FIG. 1 so as to cope with arbitrarily determined data. Each can input desired data. FIG. 4 is a diagram showing an initial screen of the input device for inputting arbitrary data to the display screen of the monitoring display system shown in FIG. FIG. 5 is a diagram showing an example of a screen in which certain data is input to the input device shown in FIG.
[0021]
First, an initial screen of an input device as a jig as shown in FIG. 4 is displayed. This initial screen is a screen similar to the display screen (monitor screen) of the monitoring display system shown in FIG. 1, and arbitrary data can be input. Here, the input data is dropped into a file, and the monitoring display system reads the data from the file and expresses it as shown in FIG. Select and input “Bandwidth (for example, HF)” in the “Equipment Name” column, “0” in the “Word No.” column, “20” in the “Total Words” column, and the like. The address is specified in the “word total” column.
[0022]
The “Bit Title” column prepares an area for 16 bits in binary, but the width of the area can be freely changed in accordance with the ICD, or the display can be turned off to make it an unused bit. To use all 16 bits, check all the columns from Bit0 to Bit15. The name input to “Bit Title” is the name of the data as described in the “Data Name” column of Table 4 shown in FIG. In the “Bit content” column, the content that functions for each bit as described in the “Content (spec)” column shown in FIG. 1 is input. For example, if “0 = squelch OFF” and “1 = squelch ON” are input in the “Bit content” item corresponding to the “squelch control” field of bit 4 in FIG. 5, 4 in the table 4 of the monitor screen 1 in FIG. “0 = Squelch OFF” and “1 = Squelch ON” are displayed in the “Content” column where the line is connected to the bit. The ICD No. group column on the right side of the screen in FIG. 5 is an area for inputting a No. for linking data.
[0023]
In this way, when data as shown in FIG. 5 is input from the initial screen shown in FIG. 4 using the input device as a jig, a monitor screen as shown in FIG. 1 is obtained. That is, when the operator inputs “Bit Title” or “Bit content” of the type shown in FIG. 5 from the input device, the data content input for each bit corresponding to the binary display data in the received data is displayed as a line. As a result, a monitor screen as shown in FIG. 1 is created. In other words, the meaning of the data allocated for each bit of the arbitrary received data can be displayed by inputting the desired data by the input device so that it can cope with arbitrarily determined data. .
[0024]
The embodiment described above is an example for explaining the present invention, and the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the gist of the invention. The above embodiment has been described with respect to a case where each data of a wireless device mounted on an aircraft is displayed on a monitor. However, the present invention is not limited to this. can do.
[0025]
【The invention's effect】
As described above, the present invention is directed to monitor display of a wireless communication apparatus having transmission data, monitoring means for receiving the transmission data and monitoring it as reception data, and display means for displaying a transmission / reception state by the monitoring means. In the system, contents of various data are assigned to the transmission data based on a bit address arbitrarily determined as an arbitrary format in advance, and the monitoring unit is configured to store various data located at the bit address based on the reception data. Since the state is determined, and the result of the determination is displayed at the position of the bit address, and the content of the determination is displayed at the position indicated by the bit address, the meaning of the communication data format can be assigned by bit. In the case of data, there is no need to individually compare the data and the contents described in documents such as specifications and ICD. And the contents of the data and specifications and ICD are displayed in association with the monitor screen. Therefore, it is not necessary to prepare specifications and ICDs in addition to the monitoring display system, and complex data can be easily read. As a result, a person other than the skilled person can use the monitor display system, so that a versatile monitor display system can be constructed.
