[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0053] Industrial Internet of Things, also known as Industrial Internet or Industry 4.0, is the integration of various acquisition and control sensors or controllers with perception and monitoring capabilities, as well as mobile communications, intelligent analysis and other technologies into all aspects of the industrial production process, thereby greatly improving manufacturing efficiency, improving product quality, reducing product costs and resource consumption, and ultimately achieving a new stage of upgrading traditional industries to intelligence. Using the industrial Internet of Things LORA communication technology, the data acquisition system is upgraded and renovated, the 485 wired is replaced by the Internet of Things wireless, and the traditional transmitter is replaced by an embedded low-power battery-powered Internet of Things sensor with a microprocessor. Wireless communication transmission has been widely used, especially in oil well sites.

[0054] Wireless communication transmission is affected by signals, distance, and device performance configuration, resulting in wireless communication transmission being slower than wired communication transmission. If the wireless transmission speed is too slow, it may affect the user experience, reduce work efficiency, and may even require additional hardware equipment or network bandwidth, thereby increasing costs.

[0055] To this end, the present application provides a message transmission solution to improve the speed of message transmission in wireless communications.

[0056] See also Figure 1 As shown, the embodiment of the present application discloses a message transmission method, including:

[0057] Step S11: receiving the current collected data fed back by the preset interface.

[0058] Receive the current collection data fed back by the preset interface, for example, the preset interface can be a pre-set sensor, that is to say, the data of the sensor acquisition device is used as the current collection data, the sensor in the present embodiment is embedded with a single-chip microcomputer (microprocessor), it should be noted that the embedded low-power battery-powered Internet of Things sensor with a microprocessor replaces the traditional transmitter, the traditional transmitter is unable to achieve true wireless transmission on the one hand, on the other hand, the microprocessor and the sensor are combined into one, so it is convenient to carry and takes up less space. In practical applications, the sensor can be a pressure sensor, a temperature sensor, a photosensitive sensor, etc., the single-chip microcomputer can be an STM32 microprocessor, and the STM32 microprocessor starts its internal digital-to-analog conversion chip (analog to digital converter, i.e. ADC) to collect sensor data, sensor data is also AD value, and the digital-to-analog conversion chip is mainly used to convert analog signals into digital signals.

[0059] In this embodiment, there are three ways to determine whether the current collected data is the last collected data in the current collection cycle, as follows:

[0060] In a first specific embodiment, after receiving the current collection data fed back by the preset interface, it also includes: determining the time difference between the current collection time of the current collection data and the first collection time of the current collection cycle; if the time difference is not less than the preset duration, the current collection data is determined as the last collection data of the current collection cycle.

[0061] A preset duration L is set, and the preset duration represents the collection cycle, that is, there are multiple collection cycles, and the sensor collects data once at regular intervals in the current collection cycle to obtain the current collection data. For example, if the collection cycle is 10 minutes, data is collected every 1 minute. If the time difference between the current collection time of the current collection data and the first collection time of the current collection cycle is not less than the preset duration, the current collection data is determined to be the last collection data of the current collection cycle. It is understandable that if the current collection data is determined to be the last collection data, the next collection data is the first collection data of the next collection cycle. It should be noted that the preset duration corresponding to each collection cycle can be set according to the specific collection scenario, for example, all collection cycles are set to the same preset duration, and different preset durations are set for different collection cycles.

[0062] In a second specific embodiment, after receiving the current collection data fed back by the preset interface, it also includes: determining a second difference between the current collection data and a preset reference value, and judging whether the absolute value of the second difference is less than a preset threshold; if the absolute value of the second difference is not less than the preset threshold, the current collection data is judged as the last collection data of the current collection cycle.

[0063] Calculate the second difference between the current collected data and the preset reference value, and compare the absolute value of the second difference with the preset threshold. If the absolute value of the second difference is not less than the preset threshold, the data difference is too large, which may be due to an abnormality in the equipment. The data needs to be immediately transmitted to the corresponding early warning device. Therefore, even if the time difference between the current collection time of the current collected data and the first collection time of the current collection cycle is less than the preset duration, the current collected data is still judged as the last collected data.

[0064] In this embodiment, before determining the second difference between the current collected data and the preset reference value, it also includes: judging whether the current collection cycle of the current collected data is the first collection cycle; if the current collection cycle is the first collection cycle, determining the first collection data of the current collection cycle as the preset reference value; if the current collection cycle is not the first collection cycle, determining the last collection data of the previous collection cycle as the preset reference value. The specific process of determining the preset reference value is:

[0065] 1) Determine the current collection cycle;

[0066] 2) If the current collection cycle is the first collection cycle, the first collection data of the current collection cycle is determined as the preset reference value;

[0067] 3) If the current collection cycle is not the first collection cycle, the last collection data of the previous collection cycle is determined as the preset reference value;

[0068] This embodiment does not use a fixed preset reference value, but tries to use data that is closer to the currently collected data as the preset reference value. In this way, there are more suitable preset reference values ​​in different scenarios.

[0069] In this embodiment, after determining the current collected data as the last collected data of the current collection cycle, it also includes: generating an emergency warning event, and reporting the emergency warning event to a corresponding preset warning processing tool, so that the preset warning processing tool can perform corresponding processing on the emergency warning event.

[0070] If the absolute value of the second difference is not less than the preset threshold, the current collected data is determined to be the last collected data of the current collection cycle, an emergency warning event is generated, and the emergency warning event is reported to the corresponding preset warning processing tool, so that the preset warning processing tool can perform corresponding processing on the emergency warning event, wherein the preset warning processing tool can also be a host, that is, the host can also process emergency warning events.

[0071] In a third specific embodiment, after receiving the current collection data fed back by the preset interface, it also includes: if the previous collection data is 0 and the current collection data is not 0, then determining the current collection data as the last collection data of the current collection cycle.

[0072] If the last collected data is 0 and the current collected data is not 0, the current collected data is determined as the last collected data of the current collection cycle. That is to say, if there is a collection data of 0 in the current collection cycle, the first non-0 collection data after the collection data of 0 is determined as the last collection data of the current collection cycle, as shown in Table 1:

[0073] Table 1

[0074]

[0075] In Table 1, 0019 is the first non-zero data after the zero data, so 0019 is the last collected data of the current collection cycle.

[0076] Step S12: If the current collected data is the first collected data or the last collected data in the current collection cycle, the current collected data is converted into a target double-byte message.

[0077] If it is determined that the current collected data is the first collected data or the last collected data in the current collection cycle, the current collected data is directly converted into a four-digit hexadecimal target double-byte message. For example, the current collected data is the first collected data, and the value is 500. The corresponding four-digit hexadecimal double-byte message is 01F4. In other words, 01F4 is directly used as the target double-byte message.

[0078] Step S13: If the current collected data is the middle collected data of the current collection cycle, determine the target single-byte message corresponding to the current collected data; wherein the middle collected data is the collected data other than the first collected data and the last collected data in the current collection cycle.

[0079] In this embodiment, determining the target single-byte message corresponding to the current collected data includes: judging whether the value of the current collected data is 0; if the value of the current collected data is not 0, determining a first difference between the current collected data and the previous collected data, and converting the first difference into a target single-byte message; if the value of the current collected data is 0, determining a preset single-byte message as the target single-byte message; wherein the preset single-byte message is different from the target single-byte message obtained based on the first difference.

[0080] If the current collected data is the intermediate collected data, it is necessary to determine whether the current collected data is 0. If so, the preset single-byte message can be directly transmitted without conversion, thereby improving the overall efficiency of message transmission. If it is not 0, the first difference between the current collected data and the previous collected data is calculated, and the first difference is converted into a target single-byte message. It should be noted that the preset single-byte message is different from the target single-byte message obtained based on the first difference. Since the converted message is a single byte as long as it is the intermediate collected data, the preset single-byte message is also a single byte. It can be understood that the first difference will not be very large, so as long as the preset single-byte message is set to a message greater than the preset threshold, such as the preset single-byte message is FF, the preset single-byte message can be distinguished from the target single-byte message obtained based on the first difference. In other words, it can be distinguished whether the first difference is 0 or the current collected data is 0, thereby reducing the time required for conversion and ensuring the stability of data transmission.

[0081] Step S14: Save the target double-byte message or the target single-byte message to a preset message array, and when a preset sending condition is met, package the double-byte message and the single-byte message stored in the preset message array, and send the packaged message to the corresponding host.

[0082] It can be understood that if the message corresponding to the current collected data is a target double-byte message, the target double-byte message is saved in the preset message array; if the message corresponding to the current collected data is a target single-byte message, the target single-byte message is saved in the preset message array; after the last collected data of the current collection cycle is saved in the preset message array, the preset sending condition is met, and then all the messages currently stored in the preset message array are packaged to obtain a packaged message, and then the packaged message is transmitted to the corresponding host. Because the packaged message is a single-byte message except for the first collected data and the last collected data, the message length is effectively reduced, so that the amount of data required to be transmitted is greatly reduced, thereby improving the message transmission efficiency.

[0083] The beneficial effects of the present application are as follows: the present application receives the current collection data fed back by the preset interface; if the current collection data is the first collection data or the last collection data of the current collection cycle, the current collection data is converted into a target double-byte message; if the current collection data is the middle collection data of the current collection cycle, a target single-byte message corresponding to the current collection data is determined; wherein the middle collection data is the collection data other than the first collection data and the last collection data in the current collection cycle; the target double-byte message or the target single-byte message is saved to a preset message array, and the double-byte message or the single-byte message in the preset message array is sent to the corresponding host. It can be seen that, on the one hand, the present application converts the double-byte message of the intermediate collected data into a single-byte message, which can greatly reduce the length of the data to be transmitted, thereby improving the message transmission efficiency. On the other hand, the first collected data or the last collected data is still a double-byte message. In this way, when the host receives the message data, it can determine the first collected data, the last collected data and the intermediate collected data in the current collection cycle, thereby facilitating the host to recover the received data and ensuring the stability of data transmission.

[0084] See also Figure 2 As shown, the embodiment of the present application discloses a specific message transmission method, including:

[0085] Step S21: receiving the current collected data fed back by the preset interface.

[0086] In this embodiment, the receiving of the current collected data fed back by the preset interface includes: receiving the current collected data fed back by the preset interface, and saving the current collected data to the collection array. It can be understood that the collection array is preset, and whenever the current collected data is received, the current collected data is converted into a four-digit hexadecimal message, and then the four-digit hexadecimal message is saved in the collection array.

[0087] Step S22: If the current collected data is the first collected data or the last collected data in the current collection cycle, the current collected data is converted into a target double-byte message.

[0088] If the current collected data is the first or last collected data of the current collection cycle, the four-digit hexadecimal message in the collection array is directly used as the target double-byte message. For example, if the record in the collection array is 0207, 0207 is directly used as the target double-byte message.

[0089] Step S23: If the current collected data is the middle collected data of the current collection cycle, and the value of the current collected data is not 0, then determine a first difference between the current collected data and the previous collected data.

[0090] In this embodiment, the determination of the first difference between the current collected data and the last collected data includes: obtaining the last collected data from the collection array, and determining the first difference between the current collected data and the last collected data. The collection array records each collected data of the current collection cycle, so that the last collected data of the current collected data can be determined, and then the first difference between the current collected data and the last collected data can be calculated. It should be noted that only when the current collected data is not 0, it is necessary to subtract the last collected data from the current collected data to obtain the first difference.

[0091] Step S24: If the first difference is a negative number, convert the absolute value of the first difference into an eight-bit binary first message, and set the highest bit of the first message to 1 to obtain a second message, and then convert the second message into a two-bit hexadecimal target single-byte message; if the first difference is a positive number, convert the first difference into a two-bit hexadecimal target single-byte message; wherein the intermediate acquisition data is the acquisition data in the current acquisition cycle except the first acquisition data and the last acquisition data.

[0092] If the first difference is a negative number, the first difference is taken as a positive number, that is, the absolute value of the first difference is obtained, and then the absolute value of the first difference is converted into an eight-bit binary first message, such as the first message is 00010011, and the highest bit of the first message is set to 1 to obtain the second message, that is, 10010011, and then the second message is converted into a two-digit hexadecimal target single-byte message, that is, 93. If the first difference is a positive number, the first difference is converted into a two-digit hexadecimal target single-byte message, for example, the four-digit hexadecimal number corresponding to the current collected data is 01F4, and the four-digit hexadecimal number corresponding to the previous collected data is 01E5, and the first difference is converted into a two-digit hexadecimal target single-byte message, that is, 0F. The details can be shown in Table 2:

[0093] Table 2

[0094]

[0095] For example, in the current acquisition cycle, a total of 7 acquisitions are made. The first acquisition and the last acquisition both convert the AD value into a double-byte message. The acquisition array corresponds to a four-digit hexadecimal number, that is, a double-byte. The four-digit hexadecimal number in the acquisition array is encoded to generate the corresponding message array. The encoding process is specifically as follows: calculate the sensor data currently collected minus the sensor data previously collected to obtain the first difference; if the first difference is negative, take the first difference as positive and convert it into an eight-bit binary number, set the highest bit of the eight-bit binary number to 1, and then convert the eight-bit binary number into a two-digit hexadecimal number; if the first difference is positive, directly convert the first difference into a two-digit hexadecimal number; store the two-digit hexadecimal number in the preset message array, wherein the two-digit hexadecimal number is a single-byte message, and add the single-byte message to the preset message array.

[0096] Step S25: Save the target double-byte message or the target single-byte message to a preset message array, and when a preset sending condition is met, package the double-byte message and the single-byte message stored in the preset message array, and send the packaged message to the corresponding host.

[0097] It can be seen that the present application divides the collected data obtained within a collection cycle into three parts: the first collection data, the intermediate collection data, and the last collection data. If the current collection data is the intermediate collection data, the first difference between the current collection data and the previous collection data is used for single-byte conversion. In other words, the double-byte message is converted into a single-byte message, thereby shortening the message length, thereby reducing the wireless communication air transmission time, and greatly improving the wireless communication efficiency of the industrial Internet of Things.

[0098] The following is a detailed description of this application. Figure 3 A specific message transmission structure schematic diagram is shown, the message transmission system includes several sensors, a data acquisition host and a wireless communication module, wherein the data acquisition host is connected to each sensor through a wireless communication line of the wireless communication module, the sensor has an embedded single-chip microcomputer, the single-chip microcomputer is used to convert each collected data fed back by the preset interface of the sensor into a single byte of the message, so as to realize message length compression and improve the speed of wireless transmission, the single-chip microcomputer is also used to pack the messages of the preset message array, and send the packed messages to the data acquisition host through the wireless communication module, the specific process is as follows:

[0099] Set the preset single-byte message to "FF", the preset threshold to "20", and set the preset duration corresponding to each acquisition cycle to 3 seconds. The STM32 microprocessor wakes itself up once every 1 second, then wakes up the low-power sensor probe, and starts the ADC to collect the sensor AD value. The ADC precision is 12 bits, and the maximum value is a 12-bit binary number, that is, the AD value range is 0--4095. In each acquisition cycle, the sensor collects data every 1 second, that is, receives the collection data fed back by the preset interface every 1 second; after booting up, it is necessary to determine whether the acquisition array and the preset message array are empty. If not, initialization processing is required, that is, clearing the acquisition array and the preset message array.

[0100] In a first specific embodiment, data collection in a first collection cycle is performed:

[0101] 1.1) Receive the first collected data of the first collection cycle (i.e., the data collected at the 0th second) fed back by the sensor, whose AD value is 500, convert 500 into a four-digit hexadecimal number 01F4, save 01F4 into the collection array, and use 01F4 as the preset reference value of the first collection cycle; directly use 01F4 of the collection array as the target double-byte message of the first collection data of the first collection cycle, and save it into the preset message array;

[0102] 1.2) Receive the second acquisition data of the first acquisition cycle fed back by the sensor (i.e., the data collected at the first second, i.e., the intermediate acquisition data), whose AD value is 519, convert 519 into a four-digit hexadecimal number 0207, and save 0207 into the acquisition array; calculate the first difference between the second acquisition data and the first acquisition data (the first difference is a positive number), convert the first difference into a two-digit hexadecimal number 13, that is, 13 is the target single-byte message after the current acquisition data is converted, and save the target single-byte message 13 into the preset message array;

[0116] The sensors of the data acquisition system are networked with the data acquisition host in a one-to-many manner using the LORA communication technology of the Internet of Things. The data acquisition host can use an embedded industrial computer, which is a computer specially designed for industrial environments. It has a compact body structure and can be used in small environments, such as some automation equipment, automated robots, and cash dispensers with small spaces. The embedded industrial computer is equipped with multiple serial ports, each of which is connected to a LORA DTU (Data Transfer Unit, i.e., wireless terminal device), which is also a LORA data transmission radio. The LORA data transmission radio uses LORA modulation technology and carefully adjusts the radio frequency based on many years of experience in wireless communication of the Internet of Things. The measured communication distance is >11.5Km, which perfectly solves the problem of ultra-long-distance communication of small data volumes in complex environments, and provides a strong wireless communication networking guarantee for Internet of Things applications in various industries. The data acquisition system includes multiple sensors, and each sensor is embedded with a single-chip microcomputer, which can be STM32. Each sensor also includes a low-power sensor probe, a LORA module, and the LORA module is used to wirelessly connect to the wireless transmission module 201, and a power supply battery. The LORA module is connected to the serial port of STM32, wherein each LORA module is set with a different address, and each address is used as the sensor address of the data acquisition system. The low-power sensor probe is connected to the ADC port of STM32. Among them, the sensor can be set to a plurality of sensors of different types or the same type, such as a pressure sensor, a temperature sensor, etc. In practical applications, the embedded single-chip microcomputer in the sensor controls the sensor to collect sensor data, and the sensor data is connected to the wireless communication module through the LORA module, and the sensor data is wirelessly transmitted to the LORA DTU connected to the data acquisition host. The LORA DTU transmits the received wireless data to the serial port of the data acquisition host, and then decodes the received message through the system software to generate data acquisition data, and stores it in the database.

[0117] See also Figure 4 As shown, the embodiment of the present application discloses a message transmission device, including:

[0118] The data receiving module 11 is used to receive the current collected data fed back by the preset interface;

[0119] The first execution module 12 is used for converting the current collected data into a target double-byte message if the current collected data is the first collected data or the last collected data in the current collection cycle;

[0120] The second execution module 13 is used to determine the target single-byte message corresponding to the current collection data if the current collection data is the middle collection data of the current collection cycle; wherein the middle collection data is the collection data other than the first collection data and the last collection data in the current collection cycle;

[0121] The message transmission module 14 is used to save the target double-byte message or the target single-byte message into a preset message array, and send the double-byte message or the single-byte message in the preset message array to a corresponding host.

[0122] The beneficial effects of the present application are as follows: the present application receives the current collection data fed back by the preset interface; if the current collection data is the first collection data or the last collection data of the current collection cycle, the current collection data is converted into a target double-byte message; if the current collection data is the middle collection data of the current collection cycle, a target single-byte message corresponding to the current collection data is determined; wherein the middle collection data is the collection data other than the first collection data and the last collection data in the current collection cycle; the target double-byte message or the target single-byte message is saved to a preset message array, and the double-byte message or the single-byte message in the preset message array is sent to the corresponding host. It can be seen that, on the one hand, the present application converts the double-byte message of the intermediate collected data into a single-byte message, which can greatly reduce the length of the data to be transmitted, thereby improving the message transmission efficiency. On the other hand, the first collected data or the last collected data is still a double-byte message. In this way, when the host receives the message data, it can determine the first collected data, the last collected data and the intermediate collected data in the current collection cycle, thereby facilitating the host to recover the received data and ensuring the stability of data transmission.
