Technical Field

[0001] The present invention relates to the technical field of device control, and particularly relates to a method for remotely adjusting device parameters through Beidou short messages. Background Art

It should not be understood that the applicant clearly believes or presumes that the applicant believes it is the prior art on the filing date of the first application of the present invention.

[0003] With the completion of the Beidou satellite navigation system, remote monitoring devices have become an indispensable part of environmental monitoring, meteorological collection, wildlife monitoring, disaster prevention and mitigation and other fields. These devices are often arranged in uninhabited areas such as virgin forests, high mountains, deserts, ocean buoys, and remote islands. There is basically no mobile network coverage in these areas. If the device needs to adjust parameters, such as adjusting frequency offset, adjusting camera angle, adjusting data collection frequency, etc., it can only be temporarily not adjusted or sent personnel to go for upgrade and adjustment, which has great difficulties in terms of completion difficulty, timeliness, labor cost, etc. Summary of the Invention

[0004] In order to realize the parameter adjustment of remote monitoring devices in remote areas and uninhabited areas, the present invention designs a method to adjust parameters in the form of Beidou short messages, which can realize the remote adjustment of the parameters of monitoring devices, greatly improve the timeliness and reduce the maintenance cost of the devices.

[0005] A method for remotely adjusting device parameters through Beidou short messages includes the following steps:

[0006] (1) Generate a parameter adjustment signal: The staff inputs the designed parameters into the computer, retrieves the identification code of the device whose parameters need to be adjusted, and the identification code corresponds to the device one by one. Generate a parameter adjustment signal by combining the parameter adjustment signal with the identification code corresponding to the device to be adjusted;

[0007] (2) Generate a simulated parameter adjustment signal: Randomly generate a virtual signal of the same type according to the parameters designed by the staff; Generate a simulated parameter adjustment signal by combining the virtual signal with a random virtual identification code, and the virtual identification code is different from the identification code;

[0008] (3) Generate a Beidou short message wireless signal: Convert the parameter adjustment signal and the simulated parameter adjustment signal into Beidou short message signals respectively and send them;

[0009] (4) After the Beidou antenna receives the short message wireless signal, it is transmitted to the Beidou short message module through a radio frequency cable, and the Beidou short message module sends the short message wireless signal to the microcontroller through a serial port;

[0010] (5) The microcontroller restores the received Beidou short message signal into a parameter adjustment signal and an analog parameter adjustment signal;

[0011] (6) The microcontroller sends the parameter adjustment signal and the analog parameter adjustment signal to the parameter adjustment control module through a serial interface;

[0012] (7) A signal screening module is provided in the parameter adjustment module. The signal screening module filters signals according to whether they contain the identification code corresponding to this device, regards the signals that do not contain the identification code corresponding to this device as invalid signals, and deletes the identification code from the parameter adjustment signal with the identification code corresponding to this device and then adjusts the parameters of the device.

[0013] Further, the Beidou antenna is connected to the Beidou short message module through a radio frequency line, receives the parameter adjustment Beidou short message wireless signal, and sends the received radio frequency signal to the Beidou short message module through the radio frequency line; the Beidou short message module internally integrates a Beidou low-noise amplification circuit, a down-conversion circuit, and a baseband processing circuit, which are responsible for completing the low-noise amplification, down-conversion, and baseband demodulation of the Beidou short message signal, demodulating the content of the Beidou short message and sending it to the microcontroller (MCU) through a serial port; the microcontroller is responsible for completing the data parsing of the received short message, parsing out the parameters to be adjusted, and sending the parameters to the corresponding parameter adjustment control module through serial interfaces such as serial port, IIC, and SPI; the parameter adjustment control module is responsible for storing the received adjustment parameters, storing the adjustment parameters received through the serial interface in the relevant parameter storage area or controlling the controlled device to perform corresponding parameter adjustment, so as to realize the function of remotely adjusting the device parameters.

[0014] Further, it also includes step (8) that the parameter adjustment module is connected to the computer signal. The computer stores the received parameter adjustment signal; the computer stores the real-time operation effect data of the device; the storage method of the parameter adjustment signal is:

[0015] Record the time point of device parameter adjustment, and record the parameter adjustment information at the corresponding time node on the real-time effect data;

[0016] Generate a predicted effect data curve after parameter adjustment on the computer. A deviation threshold is set on the computer. If the deviation between the real-time effect data after parameter adjustment and the predicted effect data curve does not exceed the deviation threshold, the computer records the real-time effect data to the next parameter adjustment time node; store the real-time effect data and the predicted effect data curve at adjacent two time nodes to a specified position and assign a time period label.

[0017] Further, it further includes step (9). If the deviation between the real-time effect data after parameter adjustment and the predicted effect data curve exceeds the deviation threshold, an alarm is issued. After receiving the alarm, the staff redesigns the parameter adjustment signal and sends it. The parameter adjustment module adjusts the parameters of the device according to the redesigned parameter adjustment signal; until the deviation between the real-time effect data after parameter adjustment and the predicted effect data curve does not exceed the deviation threshold.

[0018] Further, it further includes step (10). After the parameter adjustment module adjusts the parameters of the device according to the redesigned parameter adjustment signal, if the deviation between the real-time effect data and the predicted effect data curve does not exceed the deviation threshold before the next parameter adjustment time node, the real-time effect data and the predicted effect data curve between the redesigned parameter adjustment signal and the next parameter adjustment time node are stored at a specified location and given a time period label; the real-time effect data and the predicted effect data curve between the time node corresponding to the parameter adjustment signal that caused the previous alarm and the last readjustment time node are stored in the problem database and given a time period label.

[0019] Further, it further includes step (11). When the staff sends the parameter adjustment signal, the expected effect curve is sent at the same time; the data stored at the specified location and the data in the problem database are used as historical data. After receiving the parameter adjustment signal, the actual effect data with the highest similarity to the expected effect is found in the historical data, and the corresponding parameter adjustment signal is compared with the parameter adjustment signal received this time. If the expected deviation is less than the set value, the parameter adjustment signal received this time is executed. If the expected deviation is greater than the set value, a confirmation signal is sent to the staff.

[0020] Further, it further includes step (12). After sending the confirmation signal to the staff, within the time period before the staff confirms, the device parameters are adjusted according to the parameter adjustment signal corresponding to the actual effect data with the highest similarity, and step (8) is executed. If the deviation between the real-time effect data after parameter adjustment and the predicted effect data curve exceeds the deviation threshold, the parameter adjustment signal received this time is executed. If the deviation between the real-time effect data after parameter adjustment and the predicted effect data curve exceeds the deviation threshold, an alarm is sent to the staff.

[0021] The embodiment of the present invention has the following beneficial effects:

[0022] The advantage of this patent is that the remote monitoring device can realize remote parameter adjustment without on-site upgrade and adjustment by personnel, greatly improving the timeliness and significantly reducing the maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 It is a flowchart of the method for remotely adjusting device parameters by Beidou short message of the present invention. Detailed Implementation Manner

[0024] The present application will be further introduced below in conjunction with embodiments.

[0025] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, in the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. Different embodiments can be replaced or combined, and for those of ordinary skill in the art, without creative efforts, other implementation manners can also be obtained based on these embodiments.

[0026] Combined with the attached Figure 1 , a method for remotely adjusting device parameters through Beidou short messages includes the following steps:

[0027] Send a parameter adjustment Beidou short message wireless signal. After the Beidou antenna receives the short message wireless signal, it is transmitted to the Beidou short message module through a radio frequency line. The Beidou short message module sends the short message wireless signal to the microcontroller through a serial port, and the microcontroller sends it to the parameter adjustment control module through a serial interface to achieve remote adjustment of device parameters.

[0028] In some embodiments of the present invention, the Beidou antenna is connected to the Beidou short message module through a radio frequency line, receives the parameter adjustment Beidou short message wireless signal, and sends the received radio frequency signal to the Beidou short message module through the radio frequency line.

[0029] In some embodiments of the present invention, the Beidou short message module internally integrates a Beidou low-noise amplification circuit, a down-conversion circuit, and a baseband processing circuit, which are responsible for completing the low-noise amplification, down-conversion, and baseband demodulation of the Beidou short message signal, demodulating the content of the Beidou short message and sending it to the microcontroller (MCU) through a serial port;

[0030] In some embodiments of the present invention, the microcontroller is responsible for completing data parsing of the received short message, parsing out the parameters to be adjusted, and sending the parameters to the corresponding parameter adjustment control module through serial interfaces such as serial ports, IIC, and SPI;

[0031] In some embodiments of the present invention, the parameter adjustment control module is responsible for storing the received adjustment parameters, the adjustment parameters received through the serial interface, into the relevant parameter storage area or controlling the controlled device to perform corresponding parameter adjustment, so as to achieve the function of remotely adjusting device parameters.

[0032] A method for remotely adjusting device parameters through Beidou short messages includes the following steps:

[0033] (1)Generate parameter adjustment signals: The staff inputs the designed parameters into the computer, retrieves the identification code of the device whose parameters need to be adjusted, where the identification code corresponds to the device one by one, and generates parameter adjustment signals by combining the parameter adjustment signals with the identification code corresponding to the device to be adjusted;

[0034] (2)Generate simulated parameter adjustment signals: Randomly generate virtual signals of the same type according to the parameters designed by the staff; Generate simulated parameter adjustment signals by combining the virtual signals with random virtual identification codes, where the virtual identification codes are different from the identification codes;

[0035] (3)Generate Beidou short message wireless signals: Convert the parameter adjustment signals and simulated parameter adjustment signals into Beidou short message signals respectively and send them;

[0036] (4)After the Beidou antenna receives the short message wireless signal, it transmits it to the Beidou short message module through a radio frequency cable, and the Beidou short message module sends the short message wireless signal to the microcontroller through a serial port;

[0037] (5)The microcontroller restores the received Beidou short message signal into parameter adjustment signals and simulated parameter adjustment signals;

[0038] (6)The microcontroller sends the parameter adjustment signals and simulated parameter adjustment signals to the parameter adjustment control module through a serial interface;

[0039] (7)A signal screening module is provided in the parameter adjustment module. The signal screening module filters signals based on whether they contain the identification code corresponding to this device, regards signals that do not contain the identification code corresponding to this device as invalid signals, and deletes the identification code from the parameter adjustment signals with the identification code corresponding to this device and then adjusts the parameters of the device.

[0040] As a preferred embodiment, the Beidou antenna is connected to the Beidou short message module through a radio frequency cable, receives the parameter adjustment Beidou short message wireless signal, and sends the received radio frequency signal to the Beidou short message module through a radio frequency cable; The Beidou short message module internally integrates a Beidou low-noise amplifier circuit, a down-conversion circuit, and a baseband processing circuit, which are responsible for completing the low-noise amplification, down-conversion, and baseband demodulation of the Beidou short message signal, demodulating the Beidou short message content and sending it to the microcontroller (MCU) through a serial port; The microcontroller is responsible for completing the data parsing of the received short message, parsing out the parameters that need to be adjusted, and sending the parameters to the corresponding parameter adjustment control module through serial interfaces such as serial ports, IIC, and SPI; The parameter adjustment control module is responsible for storing the received adjustment parameters, the adjustment parameters received through the serial interface, in the relevant parameter storage area or controlling the controlled device to perform corresponding parameter adjustment, so as to realize the function of remotely adjusting the device parameters.

[0041] As a preferred embodiment, it further includes that the parameter adjustment module described in step (8) is connected to the computer signal, and the computer stores the received parameter adjustment signal; real-time operation effect data of the device is stored in the computer; the storage method of the parameter adjustment signal is as follows:

[0042] Record the time point of device parameter adjustment, and record the parameter adjustment information at the corresponding time node on the real-time effect data.

[0043] Generate a predicted effect data curve on the computer. A deviation threshold is set on the computer. If the deviation between the real-time effect data after parameter adjustment and the predicted effect data curve does not exceed the deviation threshold, the computer records the real-time effect data until the next parameter adjustment time node; store the real-time effect data and the predicted effect data curve between two adjacent time nodes at a specified position and assign a time period label.

[0044] It should be noted here that: the deviation threshold is comprehensively set according to needs and the usage of the device, and is preset. Those skilled in the art can adjust it according to needs. It can be that the deviation threshold is ±10%, or it can be 5%, which is not limited here. Storing the data with qualified effects is for reference when making similar adjustments in the future.

[0045] As a preferred embodiment, it further includes step (9). If the deviation between the real-time effect data after parameter adjustment and the predicted effect data curve exceeds the deviation threshold, an alarm is issued. After receiving the alarm, the staff redesigns the parameter adjustment signal and sends it. The parameter adjustment module adjusts the parameters of the device according to the redesigned parameter adjustment signal; until the deviation between the real-time effect data after parameter adjustment and the predicted effect data curve does not exceed the deviation threshold.

[0046] It should be noted here that: during parameter adjustment, due to problems such as the experience of the staff or the deviation between the ideal conditions and the actual conditions, the actual effect is not ideal. At this time, readjustment is required, and then it is necessary to compare with the predicted effect.

[0047] As a preferred embodiment, it further includes step (10). After the parameter adjustment module adjusts the parameters of the device according to the redesigned parameter adjustment signal, if the deviation between the real-time effect data and the predicted effect data curve does not exceed the deviation threshold before the next parameter adjustment time node, store the real-time effect data and the predicted effect data curve between the redesigned parameter adjustment signal and the next parameter adjustment time node at a specified position and assign a time period label; store the real-time effect data and the predicted effect data curve between the time node corresponding to the parameter adjustment signal that caused the alarm before and the last readjustment time node in the problem database and assign a time period label.

[0048] The results that meet expectations are stored, and the parameters with problems should also be stored. When similar adjustments occur in the future, if some insurmountable objective factors cause the staff to still make adjustment plans similar to the previous problematic parameters, the staff can be reminded. Of course, these data can also be used as a reference for the staff before formulating a plan.

[0049] As a preferred embodiment, the method further includes step (11) that when the staff sends a parameter adjustment signal, the staff also sends an expected effect curve; the data stored in the designated location and the data in the problem database are used as historical data; after receiving the parameter adjustment signal, the staff searches for the actual effect data with the highest similarity to the expected effect in the historical data and compares the corresponding parameter adjustment signal with the parameter adjustment signal received this time; if the expected deviation is less than the set value, the parameter adjustment signal received this time is executed; if the expected deviation is greater than the set value, a confirmation signal is sent to the staff. The expected effect is the effect that the staff wants to achieve after adjusting the parameters; after comparing it with similar historical data, if the expected and predicted data are similar, but the adjustment parameters are significantly different from the previous adjustment parameters, the staff should confirm the result.

[0050] As a preferred embodiment, the method further includes step (12) of adjusting the equipment parameters according to the parameter adjustment signal corresponding to the actual effect data with the highest similarity within the time period before the confirmation of the staff after sending the confirmation signal to the staff, and executing step (8). If the deviation between the real-time effect data after parameter adjustment and the predicted effect data curve exceeds the deviation threshold, the parameter adjustment signal received this time is executed. If the deviation between the real-time effect data after parameter adjustment and the predicted effect data curve exceeds the deviation threshold, an alarm is issued to the staff. Before confirmation, in order to ensure the normal operation of the equipment, considering that the historical data is the data after actual operation and may be more executable, the historical parameters are executed first. Due to changes in equipment, environment, etc., the historical data may not meet expectations after use. At this time, considering that the new data sent by the staff may be more scientific, the newly received parameter adjustment data is executed. If it is still not as expected, the staff is asked to provide feedback.

[0051] It should be noted that the above embodiments can be freely combined as needed. The above description is only the preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
