The connection 4 12 series is a personal computer 1 并 谭 tan (Qiu she! port), serial 埠 (c〇Mp〇rt) or universal serial bus (usb), the transfer circuit board Η contains the signal box and power supply. The personal computer 1 is connected to the display 16 by the transfer board M to update the display 16 display. However, the signal using the external transfer board is susceptible to interference, and the external transfer board 14 is relatively complicated to operate' while the transfer board 14 is easily damaged. In addition, when it is necessary to update a plurality of display hoof bodies, such a method is time consuming and inconvenient, and is prone to mistakes and confusion. ^, the transfer circuit board mosquito _ display _ body, the user:: in the case of: power: board, 'can not update the display shaft, can only be the manufacturer or service station, not only will increase manufacturing The cost of the business, for:: one: _ more, == users and r can update the display's body, manufacturer or service, save a good _, the convenience of the device is convenient. There is a need to manage a large number of displays from the ride. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a solution to the above problems. 200920134 The present invention provides a method for updating a display, a first display and a second display, and comparing the first and second displays to the second body, which is set in the tool holder The new _ body is the master, and the other display and the master will align the new version to the slave. ',,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, The second version of the blade is newer than the first -_. When =: the initial body, take the knife body, first establish the first - display 22 fish first | _ update brother - display device 22 22 24 J ^ connection, wired connection method can use the line connection method Light connection 10(10)(5) thing====digital signal type can use blue buds _) or infrared _= yes = connection side update first - display 22, ± wired connection mode second display 24 'and then start the first One display and two connection _ 妾 first display 22 to the second - display 22 on the body of the body update program, for example, press QSD ^ = editor (1) coffee een splay, 0SD) start (four) update program, that is, open ... firmware. Through the wireless connection, the number of the driver is not robbed 22 - the specific display on the display 22 _, after the new procedure, the first - display (five) 22 set Liuye ribs more illusion - the state of the 24 Establish a connection, 200920134 object of the display 22. In addition, when the read version of the first display 1122 or the second display 24 is directly activated, the display of the new version of the initial display may be directly activated. The other display will be updated. Referring to Figure 3, Figure 3 is a functional block diagram of Figure 2 of the present invention. The first-display device 22 includes a first signal interface 22, a first micro processing unit (MCU) 223, and a first-memory milk. The second display % includes a second signal interface 24 - a second micro processing unit such as a second memory 245. In the present embodiment, the first memory 22 and the second memory are non-volatile (the leg (10) is wired in a wired manner _ the first signal interface 221 and the first: the signal interface 241 is followed by the first display 22 The update procedure. In the case of the connection work, the first microprocessor unit of the first display 22 detects the second microprocessor unit 243 of the second display 24 and notifies the second microprocessor unit 243 to back up the second The micro-processing unit 223 of the first display 22 also backs up the first-to-first memory 225. After the second-moving body is backed up, the second micro-processing unit 243 notifies the first-micro The processing unit 223 has completed the dynamic backup. After receiving the response from the second micro processing unit 243, the second micro processing unit 223 determines whether the first and second bodies are the new (four) body. In this embodiment, The first display 22 has the old version of the blade body, and the second display 24 has the new version of the blade body. The first micro processing unit 223 sets the first display 22 as a slave and sets the second display to the master. End 'and subsequent Wei blade update procedure by the second micro processing unit For example, the control (the first display 22 is regarded as one of the second displays 24, and the processing unit 243 copies the new firmware stored in the second memory 245 to the first memory 225' and utilizes the firmware. The version date, the version number, or the checksum confirms whether the copy data is correct. If the copy data is completely correct, the second micro processing unit 243 loads the new firmware stored in the first memory 225 into the first display 22 Processing unit 223. Finally, the second micro processing unit 243 resets the first display to complete the firmware update procedure. It should be understood that the first memory 225 of the first display 22 and the second memory of the second display 24 The body 245 is not necessary. In the above-mentioned further procedure, the second display 24 can also directly load the first version of the first display 22 of the first display 22, but the second update unit can increase the body update program. Please refer to FIG. 4, which is a flowchart of a method for updating a display body according to the present invention. According to an embodiment of the present invention, when the display is updated, only two devices are connected. _ body version of the display, you can _ have a new _ body display to update the other - display _, update the display _ the method is as follows step 110: with two wired or unconnected branches coupled to the display, And starting the firmware update program of one of the displays; Step 120: Whether the display of the booting update program can detect another display, and the right display is successful, indicating that the two displays are successfully connected, and communication can be established, and step 130 is performed. Or not, 矣 + step 180; the display fails to connect the monitor, stepping: the micro-processing unit of the two monitors respectively back up the respective ones in the 10 200920134 memory; Step 140: Open the body update The display of the program compares the version of the two monitors. If the two displays the same version of ||, the steps are encouraged; if the two displays the same version of H, the display of the new _ body is set to - the master End, the display with the old version of the body is set to a slave end 'to step 150; Step 150: the main control end will copy the new hoof body in the memory of the employee's end; the apology is responsible for copying the copy to the Langdang中之_资料If the data is the same, go to step 170. If it is different, go to step 15〇; Step Π0: Main (4) Miscellaneous end (4) towel _ #料载In the micro processing unit; Step (10)··Reset the slave end, and end the update program of the two monitors. The method of updating the display of the present invention can be used for wired or wireless display of different versions of the display, and can be used for display (11) to (4). Update the display of the monitor and the second monitor and activate the - (4) display H (four) gift update program will compare the first - display as the second and right = f this, and set the display with the new version of the 11 For the main control terminal, the display of the residual body = _ is 11 - the slave, and finally the new terminal will get along with the new version _ from the phase of the city. Do not use a 9 to reduce the display = the hidden body to back up the display _, can increase the display of the display knife 200920134 is a secret. The invention provides a simple method for updating the display (4), which does not require additional tools, and only connects two displays, so that the two displays can be kept in the latest version, especially for f to manage a large number of displays. The passer is more convenient. The above description is only a preferred embodiment of the present invention, and all the simplifications and simplifications of the patent scope according to the present invention are related to the han yi circumference of the present invention.
