Description

Technical Field

[0001] The present invention relates to the technical field of automobile scales, and in particular to an automobile scale instrument system based on wireless communication. Background Art

[0002] In the application of automobile scales, there are usually multiple sensors under the scale platform. The instrument collects the force signals of each sensor through the communication bus, and obtains the current weighing weight after certain data processing. Before use, the operator needs to operate on the instrument, and the main process is as follows: Step 1: Connect all sensors to the bus; Step 2: Network and set the pressure angle to set the sensor address, and locate the address of each sensor under the scale platform; Step 3: The operator checks the internal code of each sensor by operating the instrument. This internal code reflects the size of the pressure applied to the sensor by the scale platform. Through this internal code data, confirm whether the scale platform is installed in place. If it is not in place, readjust the installation of the sensor and then look at the internal code. Step 4: The operator presses the scale platform position corresponding to each sensor with an object of a certain weight. If the data displayed on the instrument is different, the operator operates the instrument to adjust the parameters of the corresponding sensor; Step 5: The operator calibrates through the instrument. In the above operation process, steps 2 to 5 require continuous operation of the instrument. If there is only one person doing this work, the efficiency is extremely low because it is necessary to walk back and forth between the scale platform and the instrument during the above process.

[0003] In this case, two operators are usually required on site, one of whom is responsible for operating the instrument, while the other is responsible for adjusting the installation of the sensor and directing other personnel to load and unload heavy objects onto the scale. During the above process, there is a lot of communication between the two operators. Summary of the invention

[0025] It should be noted that in the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0028] like Figure 1 As shown, this embodiment provides a vehicle weighing instrument system based on wireless communication, including an instrument with an interface; a conversion head electrically connected to the interface on the instrument to form a communication protocol conversion; and a mobile terminal electrically connected to the conversion head so that the content displayed in the mobile terminal is consistent with the content displayed on the instrument.

[0029] The conversion head includes a communication module and a power supply module. The communication module is configured with a communication conversion protocol, so that the data signal output by the instrument is converted into a wireless data signal, and the mobile terminal can receive the wireless data signal to process the data and display it on its interface.

[0030] After the power supply module is electrically connected to the interface, it can obtain a power signal from the instrument to supply power to the communication module.

[0031] The adapter can be considered as a converter, which is small and easy to carry. It only needs to be plugged into the DB interface of the existing instrument and can be used after being connected to the mobile terminal through the communication module.

[0032] The mobile terminal is electrically connected to the converter head by wireless communication, which can be any communication method such as Bluetooth or WIFI. The instrument data obtained by the converter head can be sent to the mobile terminal for display via wireless signals, so the operator does not have to stand near the instrument all the time, and can view the instrument data in real time when the sensor of the symmetry table needs to be adjusted.

[0033] Specifically, the adapter can convert the RS232 signal (UART) used by the instrument into a wireless signal such as Bluetooth or WIFI, and send the data to the mobile terminal connected thereto through the wireless signal.

[0034] Furthermore, a mobile terminal, such as a mobile phone or a tablet computer, is equipped with a terminal application software, and the terminal application software is equipped with an interface consistent with the instrument, such as Figure 2 and Figure 3 shown.

[0035] After the terminal application software establishes communication with the instrument, it obtains the model parameters of the instrument through the conversion head, and can determine the instrument interface to be displayed according to the model of the instrument, thereby copying the entire interface displayed on the original instrument to the terminal application software.

[0036] Then, the vehicle weighing data information displayed in the instrument is transmitted to the terminal application software through the conversion head for display, so that the terminal application software displays the same data as that on the instrument display screen, and the operator can also see the data information displayed on the instrument even if he is far away from the instrument.

[0037] Further, such as Figure 2 and Figure 3 As shown, the terminal application software is configured with the same key window as that on the instrument, which means that the key operation of the terminal application software is equivalent to the key operation on the instrument.

[0038] Specifically, as long as the operator touches a button on the interface of the mobile phone or tablet computer, it is equivalent to pressing the corresponding button on the instrument, thereby facilitating the operator to operate the instrument.

[0039] Thus, the data in the meter can be transmitted to the mobile terminal for display through this system. When the operator needs to operate the meter according to the currently displayed data, he can operate through the touch buttons displayed on the terminal application software. The operation signal will be transmitted back to the converter through the wireless signal, and the communication module in the converter will convert it into an RS232 signal (UART) compatible with the meter according to the communication conversion protocol. After the signal is transmitted back to the meter, the meter will perform the corresponding operation.

[0040] The instrument system provided in this embodiment successfully interconnects the mobile terminal and the instrument through a simple conversion head, and the conversion head can directly draw power from the instrument interface without the need for additional equipment to provide power.

[0041] Then, operators only need to run the terminal application software on the mobile phone or tablet computer used for daily basic communication and connect to the instrument via wireless communication. The operator can then view the instrument data directly on the mobile phone or tablet computer, thus eliminating the need to carry an additional handheld device for operation.

[0042] Finally, since the display interface and buttons on the mobile phone or tablet are exactly the same as those on the instrument, the operator only needs to touch the buttons on the interface of the mobile phone or tablet, which is equivalent to pressing the corresponding buttons on the instrument. In this way, only one operator is needed to adjust the sensor under the scale on site, and the instrument can be operated in real time after the adjustment, which improves operating efficiency.

[0043] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
