Alternative embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Example 1
Fig. 1 is a schematic structural diagram of a wireless gateway transmission system according to an embodiment of the present invention, as shown in fig. 1, the system includes:
the information channel detection module is used for detecting the network congestion state; specifically, the information channel detection module is configured to send a request code to an external system through a network interface at regular or irregular time, receive a feedback code of the external system, and determine an interval time between the request code and the feedback code, so as to determine a network congestion state.
The processor is used for determining transmission grades of different information according to the network congestion state; wherein the transmission level includes a transmission frequency and a transmission threshold.
And the information filtering module is used for filtering the information according to the transmission grade. Specifically, the information filtering module is used for controlling the information filtering speed according to the transmission frequency of different information; filtering information according to transmission thresholds of different information; the transmission threshold includes a first transmission threshold and a second transmission threshold, information higher than the first transmission threshold is filtered out, and/or information lower than the second transmission threshold is filtered out, wherein the first transmission threshold is larger than the second transmission threshold. When the method is applied specifically, the information which can be set to be higher than the first transmission threshold value according to the requirement is filtered (namely, abnormal data are filtered); information that is set as below the second transmission threshold may also be filtered (i.e., filtering anomalous data) as desired; it may also be provided that information between the first transmission threshold and the second transmission threshold is filtered.
And the information conversion module is used for converting the filtered information into wireless network data and then sending the wireless network data to an external system.
The different information in this embodiment may be understood as different parameters, such as operating parameters involved in the operation of the device, etc. The wireless gateway transmission system can adopt a corresponding information filtering strategy according to the network congestion state, and reduces information with higher or unimportant transmission frequency. The method solves the problem that the timeliness of the information is not guaranteed when the network is congested, optimizes the use of an information channel, and enables the information to be quickly sent to an external system.
When the method is specifically applied, the corresponding relation between the interval time of the request code and the feedback code and the network congestion state can be preset, for example, a plurality of preset time intervals are set to correspond to different network congestion states, and the longer the interval time is, the more serious the network congestion state is indicated.
And the network congestion state corresponds to the transmission grade, if the network congestion state is serious, the transmission grade corresponding to the higher grade is lower, for example, the transmission frequency is lower, the difference between the first transmission threshold value and the second transmission threshold value is larger, therefore, when the network is more congested, the transmission frequency of information is reduced, the data interval between the first transmission threshold value and the second transmission threshold value is compressed, for example, the first transmission threshold value is reduced, the second transmission threshold value is increased, and the smoothness and timeliness of information transmission are ensured as much as possible. Of course, the transmission level may also be determined according to the network congestion status and the priority, for example, if the network congestion status is severe, the transmission frequency of the information with the higher priority is higher than that of the information with the lower priority, and the data interval between the two transmission thresholds of the information with the higher priority may also be set to be narrower than the data interval between the two transmission thresholds of the information with the lower priority (i.e. less information with the higher priority is filtered and more information can be successfully transmitted), so as to ensure that the information with the higher priority (i.e. the key information) can be successfully and timely transmitted.
In order to realize the visualization of the congestion situation of the information channel, the embodiment provides a preferred implementation manner, namely the system further comprises: the information filtering control screen is used for receiving and displaying the network congestion state sent by the processor; the system is also used for receiving and displaying the setting information of the transmission grades of the different information of the user; and the information filtering module is also used for detecting the transmission frequency of the current information and uploading the transmission frequency to the information filtering control screen for real-time display. The information filtering control screen can be internally provided with a data protocol table, is used for analyzing the input information and visualizing the transmission grade and the transmission frequency of the information, receives and displays the network congestion state sent by the processor, sets the priority of the information and the transmission grade of the information, and can be removed only once or be configured at any time.
The embodiment also provides a wireless gateway, which comprises the wireless gateway transmission system. Fig. 2 is a schematic structural diagram of a wireless gateway according to an embodiment of the present invention, and as shown in fig. 2, the wireless gateway includes a network interface, an information channel detection module, a processor, an information filtering module, an information conversion module, and an information filtering control screen. The information filtering control screen can display the network congestion state, the information transmission frequency and the transmission threshold value. It should be noted that, the user may manually set the transmission level of the information in different network congestion states through the information filtering control screen, may limit the number of the same information uploaded in a unit time, and may set the transmission threshold of the information, for example, the boundary value between the abnormal data and the normal data is used as the transmission threshold, and the transmission threshold may include a first transmission threshold and a second transmission threshold, that is, the higher or lower data is used as the abnormal data, so as to upload the abnormal data in time. Based on the above, the information filtering control screen is configured to receive setting information of a user, and according to the setting information, a transmission level corresponding to a network congestion state can be confirmed.
For example, the information filtering control screen displays that the wireless gateway uploads the temperature 60 times a second, the voltage 20 times a second, the user sets the priority of the temperature to be low, the first transmission threshold of the temperature to be 70 degrees, the second transmission threshold to be 0 degrees, and the priority of the voltage to be medium. When the network is slightly congested, the wireless gateway limits the frequency of uploading the temperature to 20 times per second while not limiting data uploads with temperatures greater than 70 degrees and/or data uploads with temperatures less than 0 degrees. When the network is congested, the wireless gateway sets the frequency of uploading the temperature to 10 times a second and the frequency of uploading the voltage to 15 times a second (because the voltage is higher priority than the temperature, the transmission frequency of the voltage is also higher than the transmission frequency of the temperature). Thereby optimizing the use of the information channel.
Example 2
Fig. 3 is a flowchart of an information filtering method of a wireless gateway transmission system according to an embodiment of the present invention, as shown in fig. 3, the method includes the steps of:
step S301, detecting a network congestion state;
step S302, determining transmission grades of different information according to the network congestion state; wherein the transmission level includes a transmission frequency and a transmission threshold;
step S303, filtering information according to the transmission grade;
step S304, the filtered information is converted into wireless network data, and then transmitted to an external system.
According to the embodiment, a corresponding information filtering strategy is adopted according to the network congestion state, so that information with higher or unimportant sending frequency is reduced. The method solves the problem that the timeliness of the information is not guaranteed when the network is congested, optimizes the use of an information channel, and enables the information to be quickly sent to an external system.
When detecting the network congestion state, the request code can be sent to an external system through a network interface at regular or irregular time; receiving a feedback code of an external system; and judging the network congestion state according to the interval time of the request code and the feedback code. Specifically, judging a preset time interval in which the interval time is located; determining a corresponding network congestion state according to a preset time interval; wherein, the corresponding relation between different preset time intervals and the network congestion state is preset. The longer the interval time, the more serious the network congestion state is indicated. If no feedback code is received, it indicates that the network congestion status is very severe.
After determining the network congestion state, determining the transmission level of different information according to the network congestion state, including: determining the priority of different information at present; determining transmission grades of different information according to the network congestion state and the priority of the different information; the corresponding relation between the network congestion state and the transmission grade is preset, and the corresponding relation between the priority and the transmission grade is preset. If the network congestion state is serious, the transmission grade corresponding to a higher level is lower, for example, the transmission frequency is lower, the data interval between the two transmission thresholds is larger (namely, the difference value between the first transmission threshold and the second transmission threshold is larger), so that when the network is more congested, the transmission frequency of information is reduced, the data interval between the two transmission thresholds of the information is enlarged (the data which can be smoothly transmitted is reduced), thereby ensuring the smoothness and timeliness of information transmission as much as possible, and reducing the data quantity of transmission. Of course, the transmission level may also be determined according to the network congestion status and the priority, for example, if the network congestion status is severe, the transmission frequency of the information with the higher priority is higher than that of the information with the lower priority, and the data interval between the two transmission thresholds of the information with the higher priority is narrower than that between the two transmission thresholds of the information with the lower priority, so as to ensure that the information with the higher priority (i.e. the key information) can be successfully and timely transmitted. More preferably, the demarcation value of the normal data and the abnormal data can be used as a transmission threshold value, so that the abnormal data is guaranteed to be uploaded in time.
After the transmission grade is determined, information filtering is carried out according to the transmission grade, and specifically, the information filtering speed is controlled according to the transmission frequency of different information; filtering information according to transmission thresholds of different information; the transmission threshold includes a first transmission threshold and a second transmission threshold, information higher than the first transmission threshold is filtered out, and/or information lower than the second transmission threshold is filtered out, wherein the first transmission threshold is larger than the second transmission threshold. Accordingly, the information filtering is realized by adopting a corresponding information filtering strategy according to the network congestion state, and then the information after the filtering operation is finished is sent to an external system, so that the use of an information channel is optimized.
In this embodiment, when the information filtering policy is set, filtering keywords may be preset, and when information filtering is performed, filtering keywords in the information may be filtered out. Thereby ensuring the transmission of effective information.
