When an operator wants to check fault information, he can only flip through different pages by pressing up and down buttons. After checking the fault information of one page, he continues to press the button to display the next page, and all fault information is displayed in multiple pages in a loop. This method has the following disadvantages: when there are many faults, multiple pages are needed, and it is cumbersome for the operator to check fault information page by page by manually pressing the button, which brings certain inconvenience to the operator, and specific faults cannot be checked, which is clumsy and not user-friendly. SUMMARY

[0008] Query all elements of the first array, obtain all non-zero fault elements, and save the non-zero fault elements to a second array;

[0009] When the button of the air conditioner detector is pressed, according to the function of the button, a first parameter is transmitted to a first function, so that the first function calculates the coordinate information of the cursor or the fault code, or a second parameter is transmitted to a second function, so that the second function finds and displays the corresponding fault sub-page; the second parameter is a corresponding element in the second array.

[0010] According to some embodiments of the present application, the method further comprises the following steps:

[0049] The air conditioner detector is an instrument for detecting whether the air conditioner has a fault. The current air conditioner detector usually displays the fault in its page. However, due to the limitation of the page size, one page cannot display all the fault information, and multiple pages are needed to display the fault information one by one. When the operator wants to view the fault information, the operator can only flip through different pages by pressing the up and down buttons. After viewing the fault information of one page, the operator continues to press the button to display the next page, and all the fault information is displayed in multiple pages. This way has the following disadvantages: when there are many faults, multiple pages are needed, and it is cumbersome for the operator to view the fault information page by page by manually pressing the button, which brings certain trouble to the operator, and the operator cannot view specific faults, which is clumsy and not user-friendly.

[0050] To solve the above problems, the application provides an air conditioner detector and a fault display method thereof, which can be used to make the detector display all the faults of the air conditioner that occur and are sent by the indoor and outdoor units according to the protocol, and all the actually occurring faults can be displayed on the same fault display page; the support fault (code) can be selected, and after the selected fault is selected, the fault information can be viewed on the fault subpage, including the fault name, the indoor and outdoor fault type, the cause and the solution method, which facilitates the user to view specific faults and solve the faults, improves the efficiency, is more user-friendly, meets the user demand, and has the automatic refreshing function. When a fault is solved or added, the fault display is automatically updated after a set time. When the user is operating, the refreshing is stopped, and the user experience is focused. The coordinates of the display area are automatically calculated by an algorithm, the fault subpage is found by the function itself, and only simple parameter transmission is needed, which greatly reduces the programming difficulty and makes the maintenance code simple and convenient.

[0051] In one aspect, the application provides a fault display method of an air conditioner detector, as shown in Figure 1 The method comprises the following steps:

[0052] Step S100: Enter the fault display page of the air conditioner detector, and the air conditioner detector detects whether the air conditioner has a fault;

[0053] Step S200: When the air conditioner has a fault, the air conditioner detector counts all the faults of the air conditioner, obtains a fault count value, and obtains the fault information of each fault, and stores each fault information in the corresponding fault subpage;

[0054] Step S300: Create a first array, and assign a variable corresponding to an element of the first array according to each occurring fault;

[0055] Step S400: Query all the elements of the first array, obtain all the non-zero fault elements, and save the non-zero fault elements to a second array;

[0056] Step S500: When the button of the air conditioner detector is pressed, according to the function of the button, the first parameter is transmitted to the first function, so that the first function calculates the coordinate information of the cursor or the fault code, or the second parameter is transmitted to the second function, so that the second function finds and displays the corresponding fault sub-page; the second parameter is the corresponding element in the second array.

[0057] Specifically, in the present example, in order to enter the fault display page of the air conditioner detector, the air conditioner detector is powered on first, so that the air conditioner detector is initialized. During the initialization process, the main function while loop of the air conditioner detector performs tasks such as dog feeding, key scanning, data analysis, and LCD display. Then, the menu of the air conditioner detector is selected through the button to enter the fault display page. It should be noted that if the air conditioner detector has completed power-on and is located in other display pages, the fault display page is entered through the button without waiting for the T refresh time.

[0058] In some embodiments of the present application, when the fault display page of the air conditioner detector is entered, the timing is started to obtain the timing value; when the button of the air conditioner detector is not pressed and the timing value reaches the preset value, the fault display page is refreshed and displayed, and the timing value and the fault count value are cleared, the timing and the fault counting are restarted, and the fault display is updated. It should be noted that during the timing process, the timing variable pu8_dis_cnt gradually increases by 1 unit of time. When pu8_dis_cnt*unit time≥T (T is a preset value), and during the entire timing process, all buttons of the air conditioner detector are not pressed, it indicates that the user does not operate the air conditioner detector during this period. At this time, the air conditioner detector will automatically refresh and display the fault display page, and restart the timing and fault counting, and update the fault display. Through such a setting, if there is a new fault or a fault has been solved, the air conditioner detector can be updated in time. If the button of the air conditioner detector is pressed during the timing process, the timing is stopped and the timing value is cleared. The button of the air conditioner detector is pressed, which means that the user is operating the air conditioner detector at this time. If the fault display page is refreshed and displayed at this time, it will affect the user's operation, therefore, the timing needs to be stopped, the timing value is cleared, and the timing is restarted.

[0059] When the air conditioner detector detects the air conditioner, it will detect all the faults that occur and are sent by the indoor and outdoor unit protocols. If there is no fault, the fault display page displays that the air conditioner is normal. If the air conditioner is detected to have a fault, all the faults that occur will be counted to obtain a fault count value gu8_err_cnt, and the fault category of each fault that occurs (indoor fault or outdoor fault) will be judged, and the corresponding macro is assigned to the variable pu8_i. For elements that do not have faults, the value of gu8_err_buff[pu8_i] is zero. Then, all elements gu8_err_buff[pu8_i] of the first array are judged in a loop. If the value of the element is zero, the variable pu8_i is incremented to judge the next element. The value of the element is not zero, which represents a fault, and the fault code is displayed, and the fault element gu8_err_buff[pu8_i] is saved to the second array ga_dis_err_buff[gu8_err_cnt]. At the same time, the cursor position of the first displayed fault is 1, and the cursor positions of subsequent faults are incremented by 1.

[0060] If the air conditioner has no fault, the fault display page displays the fault count value gu8_err_cnt=0. If the air conditioner has a fault, the fault display page will display all the faults that occur, but the detailed fault information of each fault will be stored in the fault sub-page, so that all the faults that occur can be displayed on one fault display page without the need to page, and when a specific fault needs to be queried, the corresponding fault sub-page is entered for viewing. When the up button / down button / return button of the air conditioner detector is pressed, the corresponding operation is performed according to the function of each button.

[0061] Specifically, when the down button of the air conditioner detector is pressed, in step S500 above: when the button of the air conditioner detector is pressed, the first parameter is transmitted to the first function according to the function of the button, so that the first function calculates the coordinate information of the cursor or the fault code, which specifically includes the following three steps:

[0062] (1) When the function of the button is the down button, the cursor position of the current cursor is obtained.

[0063] (2) When the cursor position of the current cursor is less than the fault count value, the first parameter corresponding to the current cursor is obtained and sent to the first function, so that the first function calculates the coordinate information of the current cursor and clears the current cursor, and then the cursor position is incremented by 1, the first parameter corresponding to the new cursor is obtained and sent to the first function, so that the first function calculates the coordinate information of the new cursor and displays the new cursor.

[0064] (3) When the cursor position of the current cursor is equal to the fault count value, and the fault count value is greater than 1, the first parameter corresponding to the current cursor is acquired and sent to the first function, so that the first function calculates the coordinate information of the current cursor and clears the current cursor, and then the cursor position is set to 1, the first parameter corresponding to the new cursor is acquired and sent to the first function, so that the first function calculates the coordinate information of the new cursor and displays the new cursor.

[0065] Specifically, the function of the first function is mainly used for calculating coordinate information, for example, calculating the coordinate information of the cursor to be cleared, calculating the coordinate information of the cursor to be displayed, and calculating the coordinate information of the fault code, etc. In the present application, three calculation modes are set for the first function, which are the calculation mode of calculating the coordinate information of the fault code, the calculation mode of calculating the coordinate information of the cursor to be cleared, and the calculation mode of calculating the coordinate information of the cursor to be displayed. The specific calculation process of the first function (i.e. A function) is as follows: Figure 2As shown, the first parameter passed to the first function includes the mode parameter (mode) and the cursor parameter (err_cnt). The first function first calculates the row and column of the required content according to the cursor parameter (err_cnt) and stores them in the row variable and the column variable, respectively, and then uses a switch statement to determine which calculation mode the mode parameter (mode) is in. The formula for calculating the row variable is pu8_row = err_cnt / ONE_ROW_MAX_NUM, where pu8_row represents the row variable, err_cnt is the cursor parameter passed to the first function, and ONE_ROW_MAX_NUM represents the maximum number of displayable faults in a row. The formula for calculating the column variable is pu8_col = err_cnt % ONE_ROW_MAX_NUM, where pu8_col represents the column variable. It should be noted that if the calculated column variable is equal to 0, it indicates that the cursor to be calculated is in the last column of the previous row. After calculating the row variable and the column variable, the corresponding calculation mode is selected through the switch statement. In this example, the mode parameter (mode) has three values, 0, 1, and 2. When mode = 0, it indicates that the first function calculates the coordinate information of the cursor to be displayed, and the calculation formula is mu8_coo_par[0] = OFFSET1 + CURSOR_R + (pu8_col - 1) * FONT_SIZE * 2, mu8_coo_par[1] = OFFSET2 + CURSOR_R + (pu8_row) * (FONT_SIZE + 8), where OFFSET1 represents the left and right offset of the display screen, OFFSET2 represents the top and bottom offset of the display screen, and a pixel point needs to be reserved to prevent black edges, CURSOR_R represents the radius of the cursor, and the shape of the cursor is a circle; FONT_SIZE represents the font size; mu8_coo_par[0] represents the X coordinate of the cursor; and mu8_coo_par[1] represents the Y coordinate of the cursor. When mode = 1, it indicates that the first function calculates the coordinate information of the fault code, and the calculation formula is mu8_coo_par[0] = OFFSET1 + pu8_col * FONT_SIZE * 2 - FONT_SIZE, mu8_coo_par[1] = OFFSET2 + pu8_row * (FONT_SIZE + 8). When mode = 2, it indicates that the first function calculates the coordinate information of the cursor to be cleared, and the calculation formula is mu8_coo_par[0] = OFFSET1 + (pu8_col - 1) * FONT_SIZE * 2 - mu8_coo_par[1] = OFFSET2 + pu8_row * (FONT_SIZE + 8).

[0066] When the function of the key is the down key, it indicates that the next fault needs to be viewed. At this time, the cursor position mu8_cursor where the current cursor is located is obtained first, and then it is judged whether the cursor position mu8_cursor is less than the fault count value. If yes, the first parameter (2, mu8_cursor) is transmitted to the first function, so that the coordinate information of the current cursor is calculated, and the current cursor (old cursor) is cleared. Then, mu8_cursor is incremented, and the first parameter (0, mu8_cursor) is transmitted to the first function, so that the coordinate information of the new cursor is calculated, and the new cursor is displayed on the display screen. If the cursor position where the current cursor is located is equal to the fault count value, it is continuously judged whether the fault count value is 1. If yes, it indicates that there is only one fault, and at this time, the down key is not processed. If the fault count value is greater than 1, it indicates that the cursor position where the current cursor is located is the position of the last fault at this time, and at this time, the down key indicates that the cursor needs to be returned to the position of the first fault. At this time, the first parameter (2, gu8_err_cnt) is transmitted to the first function, so that the coordinate information of the current cursor is calculated, and the current cursor (old cursor) is cleared. Then, mu8_cursor is set to 1, and the first parameter (0, mu8_cursor) is transmitted to the first function, so that the coordinate information of the new cursor is calculated, and the new cursor is displayed on the display screen.

[0067] In some embodiments of the present application, when the up key of the air conditioner detector is pressed, the following steps in step S500 are performed: when the key of the air conditioner detector is pressed, according to the function of the key, the first parameter is transmitted to the first function, so that the first function calculates the coordinate information of the cursor or the fault code, which specifically includes the following three steps:

[0068] (1) When the function of the key is the up key, the cursor position of the current cursor is obtained.

[0069] (2) When the cursor position of the current cursor is greater than 1, the first parameter corresponding to the current cursor is obtained and transmitted to the first function, so that the first function calculates the coordinate information of the current cursor and clears the current cursor. Then, the cursor position is decremented by 1, the first parameter corresponding to the new cursor is obtained and transmitted to the first function, so that the first function calculates the coordinate information of the new cursor and displays the new cursor.

[0070] (3) When the cursor position of the current cursor is equal to 1, and the fault count is greater than 1, the first parameter corresponding to the current cursor is obtained and transmitted to the first function, so that the first function calculates the coordinate information of the current cursor and clears the current cursor. Then, the cursor position is set to the fault count value, the first parameter corresponding to the new cursor is obtained and transmitted to the first function, so that the first function calculates the coordinate information of the new cursor and displays the new cursor.

[0071] Specifically, when the function of the key is the up key, it indicates that the previous fault needs to be viewed. At this time, the cursor position mu8_cursor where the current cursor is located is obtained first, and then it is judged whether the cursor position mu8_cursor is greater than 1. If yes, the first parameter (2, mu8_cursor) is transmitted to the first function, so that the coordinate information of the current cursor is calculated, and the current cursor (old cursor) is cleared. Then, mu8_cursor is decremented, and the first parameter (0, mu8_cursor) is transmitted to the first function, so that the coordinate information of the new cursor is calculated, and the new cursor is displayed on the display screen. If the cursor position mu8_cursor where the current cursor is located is 1, and the fault count value gu8_err_cnt is 1, it indicates that there is only one fault, and the up key is not processed at this time. If the cursor position mu8_cursor where the current cursor is located is 1, and the fault count value gu8_err_cnt is greater than 1, it indicates that the cursor position where the current cursor is located is the position of the first fault at this time, and the up key indicates that the cursor needs to be returned to the position of the last fault at this time. At this time, the first parameter (2, 1) is transmitted to the first function, so that the coordinate information of the current cursor is calculated, and the current cursor (old cursor) is cleared. Then, mu8_cursor is set to gu8_err_cnt, and the first parameter (0, mu8_cursor) is transmitted to the first function, so that the coordinate information of the new cursor is calculated, and the new cursor is displayed on the display screen.

[0072] In some embodiments of the present application, when it is confirmed that the key is pressed, the step S500 described above: according to the function of the key, the second parameter is transmitted to the second function, so that the second function finds and displays the corresponding fault sub-page, specifically including the following two steps:

[0073] (1) When the function of the key is the confirmation key, according to the cursor position of the current cursor, the corresponding element in the second array is selected as the second parameter;

[0074] (2) The second parameter is transmitted to the second function, so that the second function finds and displays the corresponding fault sub-page.

[0075] Specifically, when the confirmation button of the air conditioner detector is pressed, the fault at the position of the cursor is selected, at this time, the corresponding fault sub-page needs to be entered. At this time, the element ga_dis_err_buff[mu8_cursor] in the second array corresponding to the current cursor is selected as the second parameter and is passed to the second function (B function), so that the second function B (ga_dis_err_buff[mu8_cursor]) is called, so that the second function finds and jumps to the corresponding fault information sub-page. It should be noted that the function of the second function is to determine which fault according to the second parameter passed, i.e. the fault number (with uniqueness), through the switch condition judgment, assign the first page of the corresponding fault information sub-page to the current page current_page variable, and the display screen updates the display according to the current page to realize the jump.

[0076] In addition, when the confirmation button of the air conditioner detector is pressed, in addition to passing the second parameter to the second function, the flag bit mb_switch_subpage_flag of the air conditioner detector is set to 1, and the page value mu16_last_page of the fault display page is saved as FAULT_PAGE_1; in the state of the flag bit being 1, when the up button or the down button of the air conditioner detector is pressed, the up / down switching fault sub-page is displayed; when the back button of the air conditioner detector is pressed, the current page is set to the recorded page value, i.e. current_page=mu16_last_page, so as to return to the fault display page, and the flag bit mb_switch_subpage_flag of the air conditioner detector is set to 0.

[0077] The fault display method of the air conditioner detector according to the embodiment of the application can be used to make the detector display all faults of the air conditioner that occur and are sent out through the indoor and outdoor machine protocol, and all actually occurring faults can be displayed on the same fault display page; the support fault (code) can be selected, and after the selected fault, the fault sub-page can be jumped to view the fault information, including the fault name, the indoor and outdoor machine fault type, the cause and the solution method, which is convenient for the user to view the specific fault / solve the fault, improves the efficiency, is more humanized, and meets the user demand; the display has an automatic refreshing function, when a fault is solved / added, after a set time, the fault display will be automatically updated; when the user is operating, the refreshing is stopped, and the user experience is focused; the coordinates of the display area are automatically calculated by the function, and the fault sub-page is found by the function itself, and only simple parameter passing is needed, which greatly reduces the programming difficulty and the maintenance code is simple and convenient.

[0078] As Figure 3As shown, the following will be described in detail with a specific embodiment of the fault display method of the air conditioner detector of the present application, and it should be noted that the following embodiments are only exemplary and not specific limitations of the present application.

[0079] As shown, the fault display method of the air conditioner detector according to the embodiment of the present application comprises the following steps: Figure 3

[0080] Step 1: After power-on, initialize the module peripherals, and the main function while loop will perform tasks such as dog feeding, key scanning, timing data analysis, LCD display, etc. Enter the fault display page by pressing the key; if it is entered from other pages of the air conditioner detector, there is no need to wait for T refresh time;

[0081] Step 2: LCD updates the display every time the fault display page is entered, and the timing variable pu8_dis_cnt is incremented by 1 unit of time;

[0082] Step 3: When there is no key pressed and pu8_dis_cnt*unit time >=T, refresh the display and clear the timing variable pu8_dis_cnt and the fault count value gu8_err_cnt;

[0083] Step 4: Then judge whether the air conditioner has a fault, if not, display normal, if yes, continue to judge the fault category (indoor unit fault or outdoor unit fault), and assign the corresponding macro to the variable pu8_i;

[0084] Step 5: Then loop to judge all elements gu8_err_buff[pu8_i] of the first array, if the value of the element is zero, then let the variable pu8_i++ to judge the next element; if not, it represents a fault, judge whether the fault number gu8_err_cnt is less than the maximum number of faults that can be displayed on a page PAGE_ERR_MAX_NUM, if yes, gu8_err_cnt++; otherwise, directly jump out of the loop, which means that the entire fault display page has been displayed, and wait for the response key function or refresh the display, i.e. Step 8;

[0085] Step 6: If gu8_err_cnt is 1, pass it to the A function to calculate the cursor coordinates and display the cursor, and record the cursor position as 1; then save the fault number gu8_err_buff[pu8_i] to the new array ga_dis_err_buff[gu8_err_cnt], pass it to the A function to calculate the fault coordinates and find the fault code, and finally call the function to complete the fault display;

[0086] ​Step 7: Then pu8_i++, if pu8_i<ERR_MAX_NUM, return Step 5, otherwise, it means that the fault has been found, and the loop is exited.

[0087] Step 8: Again, it is judged whether a key is pressed or not, if yes, the timing time pu8_dis_cnt is cleared, if no, return Step 2; if the display fault count value gu8_err_cnt=0, it is not processed and returns to Step 2, otherwise, the key function is judged, the down key judges whether the cursor position mu8_cursor is <gu8_err_cnt, if yes, the A function is called with parameters to clear the old cursor and mu8_cursor is incremented; otherwise, it is judged whether gu8_err_cnt is 1, if yes, the down key is invalid and is not processed, otherwise, the function A(2, gu8_err_cnt) is called to clear the old cursor, and mu8_cursor=1; finally, the function A(0, mu8_cursor) is called to calculate the coordinates and display the new cursor; the up key judges whether mu8_cursor>1, if yes, the A function is called with parameters to clear the old cursor and mu8_cursor is decremented; otherwise, it is judged whether gu8_err_cnt is 1, if yes, the up key is invalid and is not processed, otherwise, the function A(2, 1) is called to clear the old cursor, and mu8_cursor=gu8_err_cnt; finally, the function A(0, mu8_cursor) is called to calculate the coordinates and display the new cursor; the confirm key selects the fault, the function B(ga_dis_err_buff[mu8_cursor]) is called to find and jump to the corresponding fault information subpage, and mb_switch_subpage_flag=1, the previous page value mu16_last_page=FAULT_PAGE_1 is saved, and Step 9 is entered; the flag bit mb_switch_subpage_flag is 1, which means that the special logic processing is entered, that is, Step 9.

[0088] Step 9: The key function is judged, the up / down key is cyclically switched to view the information of the subpage; the return key returns to the parent page, and the current page current_page=mu16_last_page, mb_switch_subpage_flag=0, and Step 2 is returned.
