There is an analysis device.
This type of operation analysis device has conventionally been used for one type of ECU, that is, for each vehicle type. This is because the writing program of the microcomputer contained in each ECU is different, the power supply voltage for operating the ECU is different, or the connection interface with the ECU is different, so It is necessary to correspond.

Also, in the conventional motion analysis apparatus of this type, the input of the condition necessary for development or diagnosis and the output of the result are all enumerated by a number, so that they are encrypted. It was in a state.

[0004]

However, these motion analysis devices require a dedicated one for each vehicle type, and therefore, even if they have almost the same appearance, they have a wide variety of different contents. However, there was a problem with work efficiency as well as the increase in cost.

On the other hand, since the input / output information is a list of numerical values, in order to obtain the true information from the encrypted information,
It is necessary to refer to a predetermined table corresponding to the input value or output value to determine which item is input or where there is a problem, and it is a complicated task that is likely to cause an input error or reading error. However, the work efficiency was extremely low.

Particularly, since the output information is a list of numerical values,
Since it is difficult to perceive changes in numerical values corresponding to time series, it has been desired to display a graph to grasp the degree of changes. This graph display is a very effective means for comparing and examining the past data and the current data after the completion of the analysis test, and therefore, a strong demand has been received from the test site.

The present invention was devised therefor, and the purpose thereof is to be able to cope with various ECUs to reduce the cost and to display the output data in a graph. Accordingly, it is an object of the present invention to provide an operation state display device of an electronic device capable of improving work efficiency during development, analysis, and the like.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment in which an operation status display device 100 for an electronic device according to the present invention is applied to an electronic control unit (ECU) of an automobile will be described. FIG. 1 shows a block diagram of a connection example between the operation state display device 100 and the ECU in the present embodiment and each processing. As you can see from this figure,
The operation status display device 100 mainly includes the interface 10
And a personal computer (personal computer). The personal computer further includes an input unit 20, a processing unit 30, a display unit 40, a waveform display unit 41, and a storage unit 5.
Configures 0.

The interface 10 is an electronic device (EC
It has a communication function that can be switched according to U), that is, depending on the vehicle type, and the power source is a vehicle cigarette lighter, a battery, or a three-power AC100V product.
This interface 10 and the personal computer are R of 12V
The S232C serial cable is connected in a straight line to exchange data between the ECU and the personal computer.

Next, the operation inside the personal computer will be described. First, the input means 20 is a part for inputting operating conditions of the ECU, and corresponds to a keyboard and a mouse of a personal computer. The processing means 30 will be described later, but the display means 40
The waveform display means 41 is a portion for visually displaying according to the output from the processing means 30 so that a person can easily recognize it, and corresponds to a display or a printer of a personal computer, and in this embodiment, it is shown in FIG. It is displayed as an image.
The storage means 50 is a part for recording and holding the data from the processing means 30, and corresponds to a floppy (registered trademark) disk or a hard disk of a personal computer.

As shown in FIG. 1, the processing means 30 has a function of reading data from the ECU, the model table, or the input means 20, or converting the data into a form that can be numerically converted or saved. That is, it has a function of processing data such as input various set values and various output values from the ECU into a predetermined format.
It is designed to be performed via application software called abView (product name).

Below, based on the flow charts shown in FIGS. 3 to 12 and the display image on the display shown in FIG. 2,
An outline of the operation of the operation state display device 100 according to this embodiment will be described. First, in FIG. 3, a file containing necessary data is designated in the initial setting in STEP 101, and then a model is selected (STEP 102). This is a procedure for selecting from a model table which ECU is to be processed in order to associate various items such as addresses and fail-safes. This model table is a file in which the conversion procedure and conversion formula of numerical values are described for each model. In the present embodiment, there are seven types, but it is possible to increase by sequential additional registration, and its function can also be changed. You can do it.

When the model is selected, the process proceeds to the next address selection process (STEP 10). This address selection is performed by selecting "Address" in the data display area of the display screen of FIG.
The input method can be selected according to the flowchart shown in FIG. 4 (STEP 11). By clicking the mouse on the designation method 201 on the display screen shown in FIG. 4 and selecting "address", the knob (knob) 202 becomes effective, and the address 203 can be directly input by turning it while dragging it with the mouse. (STEP 13). On the other hand, when the designation method 204 is clicked with the mouse and “Label” is selected from the menu ring, the knob disappears and the label selection 205 becomes possible,
Various items (0300TEMP in FIG. 2) can be selected (STEP 12).

When the address selection processing is completed, the procedure goes to the confirmation procedure of the ON-OFF state (whether to display or not) of the access SW 206 (STEP 103), and the access SW 20
When 6 is ON, the procedure shifts to the procedure for determining the attribute (S
TEP 104). This step is a procedure for determining whether it is fail-safe or A / D (analog / digital conversion data), and in the case of A / D, shifts to the serial reading process (STEP 20) of the left flow in FIG.

In the serial reading process (STEP 20), the address selection process (STEP 1) is performed as shown in FIG.
The personal computer issues a read request to the ECU to send the address data specified in (0) (STEP 2
1) When there is a read request, the personal computer creates serial data and sends it serially to the ECU (STEP
22). If no error occurs on the way (STEP2
3) Since the data for the request is returned from the ECU, the serial data is received and written in the array (STEP 25), while if an error occurs, it is displayed as "read failure" (STEP 24).

When the serial data is received, the process proceeds to the next serial write process (STEP 30). In this procedure, as shown in FIG. 6, first, it is determined whether or not there is a write request (STEP 31), and if there is a request, serial data is created, serially transmitted, and written in the memory of the ECU (STEP 32). Specifically, when the write SW 207 in the data display area of FIG. 2 is ON (when a write request is made), for example, data for changing the operating weight of the handle is created by turning the knob 209 and written. The written data is displayed in the write data 208.

When the serial writing process (STEP 30) ends, the A / D display process (STEP 40) starts. In this procedure, as shown in FIG. 7, first, data is read from the array (STEP 41), and it is determined whether the read data is 1 data or 2 data (STE).
(P42) When 1 data, decimal and hexadecimal numerical values are displayed in the areas 210 and 211 as they are (STEP4
4) After that, numerical conversion processing is performed (STEP 45) and the converted value data is displayed on the converted value 212 (STEP 4).
6). On the other hand, when the read data is 2 data, upper and lower data are combined and combined (STEP 43), the combined value is displayed in each area 210, 211, and the converted value data is displayed as in the case of 1 data ( STEP45,
46). Here, the data is combined and synthesized only when the operation check target ECU is 8 bit CPU and 16 bit C
This is because it can be handled by PU as well, and 8bitC
In the case of PU, it is directly read as one data, 16b
In the case of itCPU, two data are combined and combined into one bit data.

The numerical value display can display three kinds of numerical values such as decimal, hexadecimal, and converted values. Conventionally, the read value had to be displayed as it is, but in the present example, it is decimal. It can be converted into a physical quantity by inputting an expression.
For example, when the data from the temperature sensor is read, in the past, it was not possible to easily grasp how many times it was, unless a separate conversion was performed and only a certain hexadecimal value was obtained. Conversion process (STEP45)
It is possible to directly read how many times the value is converted and displayed by the conversion formula read from the model data file.

When the A / D display process (STEP 40) is completed, the process proceeds to the waveform display process (STEP 60). This procedure is processed by the waveform display means 41, and data is read from the array as shown in FIG. 9 (STEP
61), the waveform is displayed as a graph 401 in the graph display area of FIG. 2 with the data on the X-axis and the data on the Y-axis (STEP 62). Here, since the data is read from the array, the data can be acquired retroactively in time, and the waveform can be viewed many times back in time.

When it is determined in step 104 that the attribute is fail data, serial read processing (STEP 20) and serial write processing (STEP 30) are performed as in the A / D (right side of FIG. 3). Flow), and shifts to fail display processing (STEP 5
0). This procedure is basically the same as the case of A / D for the data to be exchanged (STEP 51), but it can be said that the display method is different. That is, as shown in FIG. 8, numerical values are displayed in the case of A / D, but in the case of failure, they are displayed by turning on or off the LED of the corresponding item (STEP 52).

Explaining this point in detail, the address selection processing is first performed in STEP 10. In this case, various inspection items are selected in the label selection 301. For example, in this example, FAIL1 of 0349 address, FAIL2 of 034A, or the like, or 0 in label selection 302 is displayed.
The memory 1 of 34C and the memory 2 of 034d are selected. Each of these label selections 301 and 302 allows you to select other types of items from the drop-down menu.
There are various inspection items as shown in Table 1.

The label selection 301 has three windows, and each window can be instantly switched so that the inspection items can be associated and checked easily. Here, each item includes FAIL, memory, prohibition, etc., but F
AIL is an item that displays the current state of the ECU, memory is an item that displays the status up to the present, and prohibition is to prohibit entry to the FAIL. These items are ECUs selected by selecting the model in STEP 102.
Tables are prepared in advance according to the above, and not all items may be included.

When the fail address is selected, ON-OFF of the access SW 303 is checked, and if ON, STEP 5 is transmitted via STEP 104, 20, 30.
8, the data is read from the array corresponding to the address as shown in FIG. 8 (STEP 51), and LED display of the corresponding item is performed (STEP 52). For example, in the case of FIG. 2, in the case of the sub sensor abnormality 304, the LED display of that portion is turned on.

The upper / lower SW 305 is the ECU to be checked 8b, as described in detail in step 40.
This is to enable both itCPU and 16-bit CPU, and in the case of 16-bit CPU, the upper 8 bits
By switching t and lower 8 bits, it is possible to inspect each data unit.

When the fail display process (STEP 50) ends, the waveform display process (STEP 60) starts. This procedure is processed by the waveform display means 41, and data is read from the array as shown in FIG.
P61), the data is displayed as a graph 401 in the graph display area of FIG. 2 with the X axis as time and the Y axis as data (STEP 62).

When the waveform display processing (STEP 60) is completed, the display data number repetition processing is performed (STEP 10).
5). This is the access SW in STEP 103.
Each process is repeated when 206, 303, etc. are ON, and OF
If F, do not repeat. By repeating this, a plurality of data of each item can be obtained, and the club display can be performed by arranging the data in the array thus obtained in time series.

After the predetermined number of repetitions, the stored data display process (STEP 70) becomes possible. This function is a function for calling and displaying the data recorded in the file processing described later, and as shown in FIG.
Graph redisplay SW (save data display SW) 501 is ON
Whether it is OFF or not (STEP 71), when it is ON, data is read from the file and written in the array (STE).
P72), followed by performing a graph display process (STEP73). In the file processing described below, it is possible to save multiple data by changing the file name, so it is possible to display the data later or look at the front, and on the go. It can be effectively used when checking and creating reports.

Decimal and hexadecimal conversion processing (STEP80)
Is not directly related to the present invention, but is provided as an optional function. That is, as shown in FIG. 11, the calculator SW
By selecting 502 (STEP 81), it is judged whether it is a decimal input or a hexadecimal input (STEP 82), and each function is converted (STEP 83, 84).
Normally, the calculator SW502 is off, so this calculator function does not operate, but by turning it on as needed, it can be used as a scientific calculator at any time.

Next address label editing process (STEP 9
0) is a function that operates by turning on the address label editing SW 503. That is, as shown in FIG. 12, address label editing SW (RAM map editing SW)
Judge whether 503 is ON or OFF (STEP 91), O
When it is N, array display processing is performed (STEP 92). This array display processing has a function of adding or changing the address label to be selected in STEP 10 or the like, and is obtained by additionally changing the address label table as shown in Table 1. In addition to various data, conversion formulas for physical quantities, for example, conversion formulas for temperature, engine speed, etc., can be input to this table. Also, this table can be edited for each model, and when checking a new ECU,
This table will be newly created. These edited / added address labels are saved in a model data file for each model and ECU (STEP94) if necessary for saving the RAM map (STEP93),
Discard if not needed.

Sampling time display of the next procedure (STEP
Reference numeral 106) is a function of displaying how long the processing described in the sampling time display window 504 of FIG. 2 is processed, and is usually about 0.1 to 0.05 seconds.
In this display, the sampling time becomes longer as the number of display items increases.

The next step is a step of selecting whether to end the above processing with a file or to end without a file. It is executed by selecting SW 505 or SW 506, and when a file and an end SW 505 are selected ( S
TEP107), data save processing is performed (STEP1
08), select the end SW506 without file (S
TEP109), and completes all processing without saving data.
