Multi-device software version update system and update method for tire pressure sensor

The invention relates to a tire pressure sensor, in particular to a multi-device software same version update system and a updating method for a tire pressure sensor.

The conventional tire pressure sensor uses a computer, a setting tool, an identification reading and writing tool or an external vehicle main body, and a plurality of tire pressure sensors in the overall system according to the requirements of its setting and use. Paired with the car host on the car. The identification and reading and writing tool is mainly designed to match the original vehicle host with the tire pressure sensing connection and display system. This is because the original vehicle host does not allow other manufacturers to modify it. Identify the literacy tool. However, if the original car mainframe itself does not have a tire pressure sensing connection and display system, then an external vehicle mainframe is required to cooperate, and the external vehicle main body itself has a sense of tire pressure. The connection and identification functions of the detector, so the identification and reading and writing tools are not required to cooperate.

When setting, the operator mainly sets the tire pressure sensor by the setting tool to activate or deactivate it, and set which tire is located, or set the frequency or label of the vehicle with the vehicle host. When in use, the tire pressure sensor that is set and activated is installed at the position of the tire nozzle, and the tire pressure sensor can detect the current tire pressure and detect the data obtained. It is wirelessly transmitted to the vehicle mainframe, which can be displayed on its display screen to allow the driver to understand the current tire pressure status of each tire. Some vehicles need to transmit the number (ID) representing each tire pressure monitor to the vehicle main body through the identification and reading and writing tool, so that the vehicle main body reads and displays the tire pressure state of the specific ID of the tire pressure monitor to avoid Read tire status of nearby vehicles

However, as various automakers continue to introduce new models, and large automakers will combine the car's main body of the tire pressure sensor with the car's own car computer, so tire pressure sensor manufacturers often need to be up to date. The code or specification is modified to the tire pressure sensor, external vehicle host, identification and reading tools, or setting tools. In addition, the tire pressure sensor manufacturers sometimes have software modifications that need to be read. The writing tool, the external vehicle main unit or the setting tool are updated, and the tire pressure sensor is updated by the setting tool. Therefore, the software update becomes a necessary action of the tire pressure sensor.

In the current system of the tire pressure sensor, when the software is updated, it is known that after the two update files are downloaded by the computer, the two update files are transmitted to the setting tool, and the setting tool is Update with one of the updates first. Thereafter, after the tire pressure sensor is connected to the setting tool, the setting tool automatically updates the tire pressure sensor. The user must use another file to update the identification and reading tool or the external vehicle host. If you forget to update or forget which file to use, it may not be able to display tire pressure due to inconsistent versions. Or an abnormal working condition. Such software update method is not convenient. During the update process, the user must remember which device the updated main body is and the corresponding file, which will cause the operator to remember or record the update process, so as to avoid Forgetting to update causes different versions between different devices, and such an update method is quite inconvenient in operation.

As shown in the first to fifth embodiments, a method for updating a multi-device software of the tire pressure sensor according to the first preferred embodiment of the present invention has the following steps:

A) Loading: As shown in Figures 2 and 3, an archive set 21 is loaded into a computer 11, wherein the archive set 21 has at least two different sub-files, in this embodiment, The number is divided into three sub-files, and is defined as a first sub-file 221, a second sub-file 222, and a third sub-file 223, respectively. Each of the sub-files 221, 222, 223 has a unique (ie, unique) file identification code 229, and the three sub-files 221, 222, 223 in the file set 21 correspond to the same version.

B) Connection: As shown in FIG. 4, at least two different devices are electrically connected to the computer 11 simultaneously or sequentially. In this embodiment, three different devices are used as an example, and are respectively defined as The first device 151, the second device 152, and the third device 153. Each of the devices 151, 152, 153 has a unique (ie, unique) device identification code 159. The computer 11 determines, by the device identification code 159, which device the connected devices 151, 152, 153 are, and the file identification codes of the sub-files 221, 222, and 223. 229 corresponds to the device identification code 159 of each device 151, 152, 153, and the contents of each of the sub-files 221, 222, 223 correspond to each of the devices 151, 152, 153. The foregoing electrical connection method may be wired or wireless, and the wired method may be through a USB interface or an RS232 interface, and the wireless method may be through a Wi-Fi or a Bluetooth interface. In the first embodiment, the three devices 151, 152, 153 are respectively a setting machine tool, an identification reading and writing tool, and an external vehicle main body; the setting machine tool can mainly be used to set the tire pressure feeling installed in each tire. The identification and reading and writing tool is used to match the original car host computer of the automobile. Since the original car factory usually does not allow the third party manufacturer to modify it, it is necessary to use the identification and reading and writing tool to cooperate externally. In order to identify the tire pressure sensor installed in each tire, the external vehicle main body is an external vehicle main body provided by the tire pressure monitor manufacturer, and the built-in self-built tire pressure sense is built-in. The identification mechanism of the detector.

C) transmission: as shown in FIG. 5, according to the correspondence between each file identification code 229 and each device identification code 159, the corresponding sub-files 221, 222, 223 are respectively transmitted by the computer 11 to the three connected simultaneously The devices 151, 152, 153 are transferred to the three devices 151, 152, 153 in a sequentially connected relationship. as well as

D) Update: After receiving the corresponding sub-files 221, 222, 223, the three devices 151, 152, 153 update their internal software according to the received sub-files 221, 222, 223.

In the foregoing step B), the three devices 151, 152, 153 are devices for setting the tire pressure sensor in terms of software update, so when there is a need for software update, it is necessary to update the device. When the original computer host computer of the user's car has a tire pressure sensing connection and display system, the identification and reading and writing tool needs to be used for external cooperation. At this time, the user's car There is no need to install the external vehicle host. Therefore, in fact, when there is a need for software update, in addition to the setting machine, only the identification and reading tool needs to be updated to complete the most basic update requirement. Moreover, when the original computer host of the car that the user is driving does not have the tire pressure sensing connection and display system, the external vehicle host needs to be installed again, at this time, the external vehicle The host itself has built-in identification mechanism to identify the tire pressure sensor produced by the company, so there is no need to install the identification and reading tool, and it is known that in fact, when there is a need for software update, In addition to the setting machine, only the external vehicle host needs to be updated to complete the most basic update requirements. At this point, in actual operation, only the two devices 151, 152, 153 need to be updated to achieve the most basic update requirements. However, for the dealer who installs the tire pressure sensor, because the client is driving in the car. Some original computer mainframes have tire pressure sensing connection and display system, but some dealers usually need to prepare the archives 21 with three different sub-files 22,222,223 to face different customers. Vehicles.

By the above steps, the setting tool machine, the identification reading and writing tool, and the external vehicle host are electrically connected to the computer 11, and if they are connected at the same time, the same file (that is, the file set) can be used once. Perform the same version of the software update. Even if the connection is not connected at the same time, as long as the computer 11 is connected, the software update operation of each of the devices 151, 152, 153 can be completed separately, and the user only needs to connect each of the devices 151, 152, 153 to the computer 11, and It is necessary to remember which device should be connected to the software update as in the prior art. Therefore, the first embodiment has an operational convenience, and an effect that the operation is simpler than the conventional technique can be achieved.

As shown in FIG. 6, it is worth mentioning that in the archive set 21 of the first embodiment, the two sub-files 221, 222, 223 can be further separated by a partition code 23, so that the three sub-files 221, 222, 223 Two partition codes 23 can be set to separate each other, and the computer 11 recognizes each of the sub-files 221, 222, 223 by the two partition codes 23. The foregoing manner of adding the separation code 23 allows the computer 11 to more easily identify each of the sub-files 221, 222, 223. However, the separation code 23 is not an essential component, and in the absence of the separation code 23, it is still possible to find each of the sub-files. The start code or the end code of the file 221, 222, 223 is used to identify each of the sub-files 221, 222, 223. Since the electronic file has a start code and an end code, it is a conventional technique and will not be described. In addition, it is also possible to determine why the seed file 221, 222, 223 is in the order of each of the sub-files 221, 222, 223.
