[0049] An air conditioner detector is an instrument used to detect whether an air conditioner has a fault. Current air conditioner detectors usually display faults on their pages, but due to the limitation of page size, one page cannot display all fault information, and multiple pages are required to display the fault information one by one. When operators want to view fault information, they can only flip through different pages by pressing the up and down buttons. After viewing the fault information on one page, they continue to press the buttons to display the next page. All fault information is displayed in a loop on multiple pages. This method has the following disadvantages: when there are many faults, more pages are required, and it is cumbersome to manually operate the buttons to view the fault information page by page, which brings certain troubles to the staff, and it is not possible to view specific faults in a targeted manner. It is clumsy and not user-friendly.

[0050] In order to solve the above problems, the present application proposes an air-conditioning detector and a fault display method thereof, which can be used to enable the detector to display all faults that occur in the air-conditioning and are transmitted through the internal and external unit protocols, and all actual faults can be displayed on the same fault display page; it supports fault (code) selection, and after selecting the fault, you can jump to the fault sub-page to view the fault information, including the fault name, internal and external unit fault type, cause and solution, which is convenient for users to view specific faults / solve faults, improve efficiency, and is more humane and meets user needs; the display has an automatic refresh function. When a fault is solved / added, the fault display will be automatically updated after a set time; when the user is operating, the refresh is stopped, focusing on user experience; the coordinates of the display area are automatically calculated through an algorithm, and the fault search sub-page is all implemented by the function itself, which only requires simple parameter passing, which greatly reduces the programming difficulty and simple and convenient code maintenance.

[0051] On the one hand, the embodiment of the present invention provides a fault display method of an air conditioner detector, such as Figure 1 As shown, the method comprises the following steps:

[0052] Step S100: Entering the fault display page of the air conditioner detector, the air conditioner detector detects whether the air conditioner fails;

[0053] Step S200: when the air conditioner fails, the air conditioner detector counts all the failures of the air conditioner, obtains the failure count value, obtains the failure information of each failure, and stores each failure information in the corresponding failure sub-page;

[0054] Step S300: creating a first array, and assigning values ​​to element variables corresponding to the first array according to each fault that occurs;

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

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

[0057] Specifically, in this example, in order to enter the fault display page of the air conditioner detector, the air conditioner detector is first powered on to initialize the air conditioner detector. During the initialization process, the main function while loop of the air conditioner detector will perform tasks such as feeding the dog, key scanning, parsing data, and LCD display. Then, the menu of the air conditioner detector is selected by pressing the key to enter the fault display page. It should be noted that if the air conditioner detector has been powered on and is on another display page, it is no longer necessary to wait for the T refresh time to enter the fault display page by pressing the key.

[0058] In some embodiments of the present invention, when entering the fault display page of the air conditioner detector, timing will start and the timing value will be obtained; when the button of the air conditioner detector is not pressed and the timing value reaches the preset value, the fault display page will be refreshed and displayed, and the timing value and the fault count value will be cleared, and the timing and the fault count value will be restarted, and the fault display will be updated. It should be noted that during the timing process, the timing variable pu8_dis_cnt will gradually accumulate 1 unit time. When pu8_dis_cnt*unit time ≥ T (T is the preset value), and all the buttons of the air conditioner detector have not been pressed during the entire timing process, indicating that the user has not operated the air conditioner detector during this period, at this time, the air conditioner detector will automatically refresh the fault display page, restart the timing and count the faults that have occurred, 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 reset. The button of the air conditioner tester is pressed, which means that the user is operating the air conditioner tester at this time. If the fault display page is refreshed at this time, it will affect the user's operation. Therefore, it is necessary to stop the timing, reset the timing value, and then restart the timing.

[0059] When the air conditioner detector detects the air conditioner, it will detect all faults that occur in the air conditioner and are sent through the internal and external unit protocols. If there is no fault, the fault display page will show that the air conditioner is normal; if a fault is detected in the air conditioner, all faults that occur in the air conditioner will be counted to obtain the fault count value gu8_err_cnt, and the fault category of each fault that occurs (internal unit fault or external unit fault) will be determined, and the corresponding macro will be assigned to the variable pu8_i. For elements that have not failed, the value of gu8_err_buff[pu8_i] is zero. Then, all elements of the first array gu8_err_buff[pu8_i] are looped to determine. If the value of the element is zero, the variable pu8_i++ is used to determine the next element. If the value of the element is not zero, it represents a fault, and the fault code is displayed. 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 fault displayed is set to 1, and the cursor positions of subsequent faults are incremented by 1 one by one.

[0060] If the air conditioner has no fault, the fault display page will display the fault count value gu8_err_cnt = 0; if the air conditioner has a fault, the fault display page will display all faults that have occurred, but the detailed fault information of each fault will be stored in the fault subpage, so that all faults that have occurred can be displayed on one fault display page without turning pages. When a specific fault needs to be queried, enter the corresponding fault subpage for viewing. When the up / down / return buttons of the air conditioner detector are pressed, the corresponding operation will be performed according to the function of each button.

[0061] Specifically, when the down-turn button of the air conditioner detector is pressed, in the above step S500: when the button of the air conditioner detector is pressed, according to the function of the button, the first parameter is passed 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:

[0062] (1) When the function of the key is a scroll down key, obtain the cursor position of the current cursor;

[0063] (2) When the cursor position of the current cursor is less than the fault count value, obtain the first parameter corresponding to the current cursor and send it to the first function, so that the first function calculates the coordinate information of the current cursor and clears the current cursor, then adds 1 to the cursor position, obtains the first parameter corresponding to the new cursor and sends it 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, obtain the first parameter corresponding to the current cursor and send it to the first function, so that the first function calculates the coordinate information of the current cursor and clears the current cursor. Then set the cursor position to 1, obtain the first parameter corresponding to the new cursor and send it 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 to calculate coordinate information, for example, to calculate the coordinate information of the cursor that needs to be cleared, to calculate the coordinate information of the cursor that needs to be displayed, and to calculate the coordinate information of the fault code, etc. In the present application, three calculation modes are set for the first function, namely, the calculation method for calculating the coordinate information of the fault code, the calculation method for calculating the coordinate information of the cursor that needs to be cleared, and the calculation method for calculating the coordinate information of the cursor that needs to be displayed. The specific calculation process of the first function (i.e., function A) is as follows: Figure 2As shown, the first parameter passed to the first function includes a mode parameter (mode) and a cursor parameter (err_cnt). The first function first calculates the required content in which row and column according to the cursor parameter (err_cnt), and stores them in the row variable and column variable respectively, and then uses the switch statement to determine which calculation mode the mode parameter (mode) is. Among them, the formula for calculating the row variable is pu8_row=err_cnt / ONE_ROW_MAX_NUM, pu8_row represents the row variable, err_cnt is the cursor parameter passed to the first function, ONE_ROW_MAX_NUM represents the maximum number of faults that can be displayed in a row; the formula for calculating the column variable is pu8_col=err_cnt%ONE_ROW_MAX_NUM, pu8_col represents the column variable. It should be noted that if the calculated column variable is equal to 0, it means that the cursor to be calculated is in the last column of the previous row. After calculating the row variable and column variable, the corresponding calculation mode is selected through the switch statement. In this example, the mode parameter (mode) can take three values, namely 0, 1 and 2. When mode = 0, it indicates that the first function calculates the coordinate information of the cursor to be displayed. 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 upper and lower offset of the display screen, and pixels need to be reserved to prevent black edges. CURSOR_R represents the radius of the cursor, and the shape of the cursor is circular; FONT_SIZE represents the font size; mu8_coo_par[0] represents the X coordinate of the cursor; 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 button is a down-flip button, it indicates that the next fault needs to be checked. At this time, first obtain the cursor position mu8_cursor where the current cursor is located, and then determine whether the cursor position mu8_cursor is less than the fault count value. If so, it is necessary to pass the first parameter (2, mu8_cursor) to the first function to make it calculate the coordinate information of the current cursor and clear the current cursor (old cursor). Then, let mu8_cursor++, and then pass the first parameter (0, mu8_cursor) to the first function to make it calculate the coordinate information of the new cursor and display the new cursor on the display screen. If the cursor position of the current cursor is equal to the fault count value, continue to determine whether the fault count value is 1. If so, it means there is only one fault. At this time, the down button is not processed. If the fault count value is greater than 1, it means that the cursor position of the current cursor is the position of the last fault. At this time, the down button 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 passed to the first function to calculate the coordinate information of the current cursor and clear the current cursor (old cursor). Then let mu8_cursor=1, and pass the first parameter (0, mu8_cursor) to the first function to calculate the coordinate information of the new cursor and display the new cursor on the display.

[0067] In some embodiments of the present application, when the flip button of the air conditioner detector is pressed, in the above step S500: when the button of the air conditioner detector is pressed, according to the function of the button, the first parameter is passed to the first function, so that the first function calculates the coordinate information of the cursor or the fault code, specifically including the following three steps:

[0068] (1) When the function of the key is to scroll up, obtain the cursor position of the current cursor;

[0069] (2) When the cursor position of the current cursor is greater than 1, obtain the first parameter corresponding to the current cursor and send it to the first function, so that the first function calculates the coordinate information of the current cursor and clears the current cursor, then subtracts 1 from the cursor position, obtains the first parameter corresponding to the new cursor and sends it 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 sent 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 equal to the fault count value, 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.

[0071] Specifically, when the function of the button is to flip up, it indicates that the previous fault needs to be checked. At this time, first obtain the cursor position mu8_cursor where the current cursor is located, and then determine whether the cursor position mu8_cursor is greater than 1. If so, it is necessary to pass the first parameter (2, mu8_cursor) to the first function so that it calculates the coordinate information of the current cursor and clears the current cursor (old cursor). Then, let mu8_cursor--, and then pass the first parameter (0, mu8_cursor) to the first function so that it calculates the coordinate information of the new cursor and displays the new cursor on the display. 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 means that there is only one fault. At this time, the flip up button is not processed. If the cursor position of the current cursor mu8_cursor=1, and the fault count value gu8_err_cnt is greater than 1, it means that the cursor position of the current cursor is the position of the first fault. At this time, the up button indicates that the cursor needs to be returned to the position of the last fault. At this time, the first parameter (2, 1) is passed to the first function to calculate the coordinate information of the current cursor and clear the current cursor (old cursor). Then let mu8_cursor=gu8_err_cnt, and pass the first parameter (0, mu8_cursor) to the first function to calculate the coordinate information of the new cursor and display the new cursor on the display.

[0072] In some embodiments of the present application, when the confirmation button is pressed, in the above step S500: according to the function of the button, the second parameter is passed to the second function, so that the second function searches for and displays the corresponding fault sub-page, which specifically includes the following two steps:

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

[0074] (2) Pass the second parameter to the second function, so that the second function searches for and displays the corresponding fault sub-page.

[0075] Specifically, when the confirmation button of the air conditioner detector is pressed, it means that the fault at the cursor position is selected. At this time, it is necessary to enter the fault subpage corresponding to the fault. 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 passed to the second function (B function), thereby calling the second function B (ga_dis_err_buff[mu8_cursor]), so that the second function searches and jumps to the corresponding fault information subpage. It should be noted that the role of the second function is to determine which fault it is based on the second parameter passed, that is, the fault number (unique), through the switch condition judgment, and assign the homepage of the corresponding fault information subpage to the current page current_page variable. The display screen updates the display according to the current page to achieve the jump.

[0076] In addition, when the confirmation button of the air-conditioning detector is pressed, in addition to passing the second parameter to the second function, the flag bit mb_switch_subpage_flag of the air-conditioning detector is set to 1, and the page value of the fault display page mu16_last_page = FAULT_PAGE_1 is saved; when the flag bit is 1, when the up button or the down button of the air-conditioning detector is pressed, the displayed fault sub-page is switched up / down; when the return button of the air-conditioning detector is pressed, the current page is set to the page value of the above record, that is, current_page = mu16_last_page, thereby returning to the fault display page, and the flag bit mb_switch_subpage_flag of the air-conditioning detector is set to 0.

[0077] According to the fault display method of the air-conditioning detector of the embodiment of the present invention, it can be used to enable the detector to display all faults that occur in the air-conditioning and are sent through the internal and external unit protocols, and all actual faults can be displayed on the same fault display page; it supports fault (code) selection, and after selecting the fault, it can jump to the fault sub-page to view the fault information, including the fault name, the internal and external unit fault type, the cause and the solution, so that the user can view specific faults / solve faults conveniently, improve efficiency, be more humane, and meet user needs; the display has an automatic refresh function, and when a fault is solved / added, the fault display will be automatically updated after a set time; when the user is operating, the refresh is stopped, focusing on the user experience; the coordinates of the display area are automatically calculated by the function, and the fault search sub-page is all implemented by the function itself, which only requires simple parameter passing, which greatly reduces the programming difficulty and simple and convenient code maintenance.

[0078] like Figure 3As shown, the fault display method of the air conditioning detector of the embodiment of the present application is described in detail with a specific embodiment below. It should be noted that the following embodiments are only exemplary descriptions and are not specific limitations to the present application.

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

[0080] Step 1: Initialize the module peripherals after power-on. The main function while loop will perform tasks such as feeding the dog, key scanning, timing data analysis, LCD display, etc. Press the key to enter the fault display page; if you enter the fault display page from other pages of the air conditioner detector, you do not need to wait for the T refresh time;

[0081] Step 2: LCD updates the display. Each time the fault display page is entered, the timing variable pu8_dis_cnt accumulates 1 unit of time;

[0082] Step 3: When no button is 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 determine whether the air conditioner has any faults. If not, it will be displayed as normal. If yes, continue to determine the fault type (indoor unit fault or outdoor unit fault) and assign the corresponding macro to the variable pu8_i;

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

[0085] Step 6: If gu8_err_cnt is 1, pass it to function A 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 function A to calculate the fault coordinates and find the fault code, and finally call the function to complete the fault display;

[0086] Step 7: Then increment pu8_i by 1. If pu8_i < the maximum number of faults ERR_MAX_NUM, return to Step 5; otherwise, it means that all faults have been searched, exit the loop.

[0087] Step 8: Determine again whether a key is pressed. If so, clear the timing time pu8_dis_cnt; if not, return to Step 2. If the displayed fault count value gu8_err_cnt = 0, do not process and return to Step 2; otherwise, determine the key function. For the down arrow key, check if the cursor position mu8_cursor < gu8_err_cnt. If so, call function A with parameters to clear the old cursor and increment mu8_cursor by 1. Otherwise, check if gu8_err_cnt is 1. If so, the down arrow key is invalid and no processing is done; otherwise, call function A(2, gu8_err_cnt) to clear the old cursor and set mu8_cursor = 1. Finally, call function A(0, mu8_cursor) to calculate the coordinates and pass the parameters to display the new cursor. For the up arrow key, check if mu8_cursor > 1. If so, call function A with parameters to clear the old cursor and decrement mu8_cursor by 1. Otherwise, check if gu8_err_cnt is 1. If so, the up arrow key is invalid and no processing is done; otherwise, call function A(2, 1) to clear the old cursor and set mu8_cursor = gu8_err_cnt. Finally, call function A(0, mu8_cursor) to calculate the coordinates and pass the parameters to display the new cursor. For the confirm key to select a fault, call function B(ga_dis_err_buff[mu8_cursor]) to search for and jump to the corresponding fault information sub-page, set mb_switch_subpage_flag = 1, save the previous page value mu16_last_page = FAULT_PAGE_1, and enter Step 9. The flag bit mb_switch_subpage_flag being 1 indicates entering special logic processing, that is, Step 9.

[0088] Step 9: Determine the key function. The up / down arrow keys are used to cycle through sub-pages to view information. The return key returns to the parent page, set the current page current_page = mu16_last_page, mb_switch_subpage_flag = 0, and return to Step 2.
