Intelligent portable data processor three tables

Road Figure 2, Figure 2, w used to regulate the display contrast, P ¨ and the FS is connected to control the size of the display character 7) micro printer on the market here, the common TPuP selection panel printer type, model 40A is a casual type of printer TPuP interface circuit shown in Figure 8. Kids in the P ¨ used to query the printer connected with the BUSY \ Cool

RS232 interface, LCD interface circuit diagram in Figure 2 Figure 3 micro-printer interface circuit and a higher level in order to better realize the communication between computers and the expansion of system functions. RS232 connection to the instrument set [『circuit, communication data rates such as 4 1200,2400,4800 and 9600 rates. Required by the user through the keyboard then select 9) temperature and humidity measurement is the function of this part of the three tables in the test collection with the environmental conditions of temperature and humidity changes in the sensor output voltage signal, converts it into digital signals, and then sent to MCU for LCD display test actual temperature and humidity environment. The requirements of this part is not strictly with the popular 12-bit AD574 ADC can be done, and without adding sample and hold device. 3 software design software design ideas, the main consideration in all grades covered by the three tables. Three tables present the type of pointer is very large, so its automated data processing can minimize the operating table ashamed staff intervention was seized,[link widoczny dla zalogowanych], and finally print the output; The system uses liquid crystal display of information, here you can use LCD can display a wealth of information advantages in the menu on the LCD screen using the software easier way to make the operation and intuitive. Software design, programming language using C51 microcontroller programming,[link widoczny dla zalogowanych], sub-voltage, \Each function block are based on three-meter testing procedures JJG12493 preparation of the corresponding data processing, interface display and function control procedures. Software design flow shown in Figure 4. AC power to test the following table to illustrate the process of software features designed software flow chart in Figure 4. The table of categories AC-DC, model D52 of a W, number 14956, at the level O. 5. First, open the instrument into the main interface, then press any key to enter the three functions that select the interface, select the power meter press Enter \Input \75V. i50V. 300V. Cutting Table No. 600V; I) 52 · w current range; 2.5A Step seal degrees with: l0 Table 绾 number:] 4956 base pull range: 150V good at the table the most Ba: 0.52.5Ac0 cricket: O1 maximum degree of closure: ] 50 ju metrics: 20'C50 Figure 5 filling out the parameters of input parameters menu, press the \indication, the standard,[link widoczny dla zalogowanych], the appreciation of the decline in value, the actual value of the cell number and error and other items, which fall in the appreciation and value (Optional) completed at the test data,[link widoczny dla zalogowanych], the standard one by the program automatically fill. in the appreciation and decline in the value of each row where the data Tim took a number key + + per program issued by voice chip voice + the key to avoid typing errors when changing at the same time the next line where the program into the jurisdiction of the data by just principles of data processing procedures, and complete to the actual value of the cell number and the error of two cut out, when the data when the program prompts tolerance tolerance warning. After all the calibration limit of the input, the program will be under the full control of the indicated value of the quantity is limited The size of the error indication largest selection error and the maximum scale to determine the range of other data tables, complete the table's data processing. data processing is complete, press ESC \management \Also choose \,[link widoczny dla zalogowanych], slight modification of the instrument after the procedure. can be composed of three tables in the semi-automatic test system or other data processing machines.
