The invention relates to a burning device and a burning method for a tire pressure sensor, in particular to a burning device and a burning method using a common identification code to simultaneously burn a plurality of tire pressure sensors.

In recent years, tire pressure sensors have become standard equipment in automobiles. Car dealers will pre-burn the communication protocol applicable to the car model into the tire pressure sensor before selling to consumers. However, since the communication protocols used by various car manufacturers are not unified, the tire pressure sensor manufacturer or repair shop must burn different communication protocols according to various car models.

Based on this situation, the previous burning devices are targeted to identify a specific tire pressure sensor, and transmit the set communication protocol to it one-to-one and sequentially. During this process, the burning device continuously sends out packets of confirmation commands, and the tire pressure sensor responds to the transmission results, which makes the burning operation quite lengthy and time-consuming.

The main cause of the above problem is that each tire pressure sensor has its own different identification code, and in order to ensure that the communication protocol is correctly transmitted to the target tire pressure sensor, rather than being incorrectly sensed by other tire pressure sensors. Receiver, so it has a confirmation mechanism. However, if you want to burn the same protocol to more In the case of a tire pressure sensor, such a confirmation mechanism is obviously not necessary, and only causes unnecessary inefficiency.

In order to improve the above-mentioned shortcomings, the present invention proposes a tire pressure sensor burning device and burning method. Before burning the communication protocol, the identification codes of all tire pressure sensors are converted to the same, and Bluetooth transmission is used. Burn the communication protocol.

The tire pressure sensor burning device includes a burning tool, a communication protocol is stored in it, and a Bluetooth transmission unit is included. The Bluetooth transmission unit is connected to each tire pressure sensor, and sends a conversion instruction to all tire pressure sensors to convert the exclusive identification codes of these tire pressure sensors into a common identification code. Among them, the burning tool uses the shared identification code to unidirectionally burn the aforementioned communication protocol to each tire pressure sensor.

Regarding the meaning of the above one-way burning, it means that since all the exclusive identification codes are converted to the same common identification code, as the signal sender, the identification codes recognized by the burning tool during the burning process are all the same. of. In this state, because each tire pressure sensor is not different to the burning tool, the burning tool only needs to unilaterally transmit the communication protocol to all tire pressure sensors, without requiring individual Request the tire pressure sensor to reply to the received communication protocol or write status, so as to save the time consumed by the sending end and the receiving end due to repeated confirmations.

In other embodiments, the aforementioned exclusive identification code or/and shared identification code can also be stored in the burning tool first, or generated by the burning tool before the start of the burning operation, and provided to the ready-to-burn through the Bluetooth transmission unit Tire pressure sensor. The aforementioned Bluetooth transmission unit can transmit the communication protocol externally through the GATT protocol or the GAP protocol. In addition, since the communication protocol burned to all tire pressure sensors is the same, the burning tool can burn the communication protocol for each tire pressure sensor at the same time.

For example, the message receiving unit may be a wireless receiver, a camera lens, or a recorder, which uses methods such as capturing digital data, machine vision, or voice recognition to obtain the exclusive identification code and the shared identification code. The message receiving unit can also be a barcode scanner, and the exclusive identification code is displayed on the aforementioned tire pressure sensor in the form of a barcode. The burning tool can also include an input unit for direct input of the exclusive identification code or the shared identification code.

In one embodiment, after the communication protocol burning is completed, the Bluetooth transmission unit sends a reply command to each tire pressure sensor. The reply command includes a verification procedure and a reply procedure. The verification procedure is to check the burning result of the communication protocol. ; The reply procedure is to reply to the inspection result of the calibration procedure and the exclusive identification code of the tire pressure sensor itself.

Figure 5 is a flowchart of the steps of a tire pressure sensor programming method according to another embodiment of the present invention.

Please refer to Figures 1 and 2, the tire pressure sensor burning device 100 includes a burning tool 200. The burning tool 200 can correspond to and burn a plurality of tire pressure sensors S at the same time, and each tire pressure sensor The detector S has an exclusive identification code EC and a shared identification code JC. Each tire pressure sensor S has a different unique identification code EC, and the common identification code JC is shared by each tire pressure sensor S, that is, the common identification code JC of each tire pressure sensor S is the same of.

The burning tool 200 has a Bluetooth transmission unit 210 and a message receiving unit 220. Before the burning operation starts, the burning tool 200 uses the Bluetooth transmission unit 210 to request the tire pressure sensor S to respond to its exclusive identification code EC (or include a shared Identification code JC), and the message receiving unit 220 is used to obtain the response signal of the tire pressure sensor S. In this way, the burning tool 200 can identify the tire pressure sensor S through the exclusive identification code EC.

Considering that the tire pressure sensor S may have a design difference, the exclusive identification code EC or/and the shared identification code JC can be stored in the tire pressure sensor S in advance, and can also be provided by the burning tool 200 and passed through The Bluetooth transmission unit 210 transmits to each tire pressure sensor S. In this embodiment, because The exclusive identification code EC and the shared identification code JC are provided by the burning tool 200, so there is no need to receive the response signal of the tire pressure sensor S, so the message receiving unit 220 can be omitted.

Further, the burning tool 200 may also include an input unit 230, which allows the operator to manually input the exclusive identification code EC or the common identification code JC, and assign it to each tire pressure sensor S. The input unit 230 may be a human-machine input interface, such as an input keyboard, a dip switch, or a touch screen, but is not limited to this. In addition, when there is more than one exclusive identification code EC obtained by the burning tool 200, the input unit 230 can also be used to select only the specific exclusive identification code EC to be converted.

As shown in Figure 2, the tire pressure sensor S includes a processing unit S10, a memory S20, and various sensors such as a voltmeter S50, S30, an accelerometer S40, a pressure gauge, and a thermometer S60. The processing unit S10 has a wireless transceiver S11 for receiving and responding to commands from the Bluetooth transmission unit 210. The memory S20 is used to store the built-in program and the aforementioned exclusive identification code EC and shared identification code JC.

As illustrated in Figure 3, before the start of the programming operation, the Bluetooth transmission unit 210 is connected to the wireless transceiver S11 of each tire pressure sensor S, and requests the processing unit S10 to reply to the exclusive identification code EC of the tire pressure sensor S . In this process, in addition to obtaining the exclusive identification code EC of each tire pressure sensor S, the burning tool 200 may also include information such as the tire position where the tire pressure sensor S is located, the current communication protocol version, or the mileage. The Bluetooth transmission unit 210 may use transmission protocols such as GATT or GAP to transmit the communication protocol to the tire pressure sensor S, but it is not limited to this.

Please refer to Figure 4, after obtaining the exclusive identification code EC of all tire pressure sensors S to be burned, the Bluetooth transmission unit 210 sends a conversion command to each tire pressure sensor S to transfer each tire pressure sensor S The exclusive identification code EC of the detector S is converted into a common identification code JC.

In the conventional burning operation, since the exclusive identification code EC of each tire pressure sensor S is different, the burning tool 200 will continuously request the tire pressure sensor S to reply to the packet to confirm the receiving end and its Burning content; after confirming that it is correct, the burning tool 200 will transmit the next piece of data and request a reply again. If more than one tire pressure sensor S is programmed at the same time, the above request and response processes also need to be performed separately, which will consume a lot of time.

The purpose of this embodiment is to directly omit the above process by converting the exclusive identification code EC into the shared identification code JC. In detail, after all the exclusive identification codes EC are converted to the shared identification code JC, the burning tool 200 uses the shared identification code JC to communicate with all tire pressure sensors S, and broadcasts to these tire pressures. The sensor S transmits the communication protocol. During the transmission process, the burning tool 200 only burns the communication protocol to the tire pressure sensor in one direction, and does not request the tire pressure sensor S to reply its data transmission status.

In this way, compared with the conventional burning process, this embodiment can solve the problem of delay caused by the confirmation of the data transmission state between the burning tool 200 and the tire pressure sensor S, thereby improving the burning efficiency.

It can be understood from the above embodiment that, since the burning tool 200 sends the same communication protocol to multiple tire pressure sensors S, there is no need to monitor whether the receiving end of the communication protocol is correct. The burning process can be multiple simultaneous get on.

In order to confirm whether the burning result is successful, the Bluetooth transmission unit 210 may send a reply command to each tire pressure sensor S after the burning of the communication protocol is completed. The reply command may include the following procedures: a verification procedure, which is to check the burning result of the communication protocol; and a reply procedure, which is a reply to the check result of the verification procedure and the exclusive identification code EC of the tire pressure sensor S itself.

For example, the reply command may request the tire pressure sensor S to detect various sensing values according to the settings of the communication protocol, and use the parameters such as whether the sensing is successfully executed, the sensing value, etc., as the burning result, together with the exclusive identification code EC Reply to the burning tool 200 together. In this way, the operator only needs to send a unified reply command after the programming is completed to confirm the programming result of each tire pressure sensor S, so as to save working time.

The aforementioned message receiving unit 220 may include a variety of forms, such as a wireless receiver, a camera lens, or a recorder, to obtain the exclusive identification code EC and the shared identification code JC by capturing digital data, machine vision, or voice recognition. The message receiving unit 220 may also be a barcode scanner, and the exclusive identification code EC may be displayed on each tire pressure sensor S in the form of a barcode for direct scanning and reading. In addition, the message receiving unit 220 can also be connected to an on-board diagnostic system (On-Board-Diagnostics, OBD) through a wired or wireless transmission path, thereby reading the exclusive identification code EC and the shared identification code JC from the vehicle host.

Step 320 is to provide a Bluetooth transmission unit 210 and operate the Bluetooth transmission unit 210 to send a conversion command to each tire pressure sensor S to convert the exclusive identification code EC of the tire pressure sensor S into a common identification code JC. Step 330 is to use the shared identification code JC to unidirectionally burn the communication protocol for each tire pressure sensor.

The technical features and purpose of the conversion of the exclusive identification code EC to the shared identification code JC are the same as those described in the implementation of the tire pressure sensor burning device 100, so the description will not be repeated here.

As described in the foregoing embodiment, the dedicated identification code EC or the shared identification code JC of the tire pressure sensor burning method 300 can also be provided by the burning tool 200 and transmitted to all tire pressure sensors S through the Bluetooth transmission unit 210. The aforementioned Bluetooth transmission unit 210 can transmit the communication protocol externally through the GATT protocol or the GAP protocol, but it is not limited thereto.

In one embodiment, the tire pressure sensor burning method 300 may further include the step of operating the burning tool 200 to simultaneously burn the communication protocol for each tire pressure sensor. That is, because the burning tool 200 only burns the tire pressure sensor S in the JC mode with the shared identification code, the operator can confirm that all the tire pressure sensors are in the common After the tire pressure sensors S using the identification code JC mode are all applicable to the same communication protocol, the communication protocol is sent to all the tire pressure sensors S in the form of broadcast, thereby achieving the effect of simultaneous mass burning.

The aforementioned tire pressure sensor burning method 300 may further include the following steps: providing a message receiving unit 220; and operating the message receiving unit 220 to obtain each exclusive identification code EC or shared identification code JC from the outside of the burning tool 200.

The above-mentioned message receiving unit 220 can be a wireless receiver, a camera lens, or a voice recorder, but it is not limited thereto. In addition, the message receiving unit 220 may also take the form of a barcode scanner, and each unique identification code EC is displayed in the form of a barcode on the tire pressure sensors S for the message receiving unit 220 to scan and read.

The technical features and specific implementations of how the message receiving unit 220 obtains the exclusive identification code EC or the shared identification code JC are as described above, so they will not be repeated here.

The aforementioned tire pressure sensor burning method 300 may further include the following steps: an input unit 230 is provided, and the input unit 230 is used to input the exclusive identification code EC or the shared identification code JC.

After the communication protocol burning is completed, the tire pressure sensor burning method 300 may further include: operating the Bluetooth transmission unit 210 to send a reply instruction to each tire pressure sensor S, and the reply instruction includes: a verification program, which To check the burning result of the communication protocol; and a reply procedure, which is to reply to the check result of the verification procedure and the exclusive identification code EC of the tire pressure sensor S itself.

According to the foregoing embodiments, the tire pressure sensor burning device 100 and the burning method of the present invention use the shared identification code JC to burn the tire pressure sensor to the communication protocol, eliminating the need for the burning tool 200 to repeatedly perform tire pressure sensor burning with different identification codes. The pressure sensor S confirms the steps of burning content, so as to overcome the problem of wasted time.

In addition, on the basis of the shared identification code JC, the burning tool 200 can be combined with the tire pressure sensor S to simultaneously burn communication protocols for multiple tire pressure sensors, thereby significantly improving the efficiency of the burning operation.
