At present, gas supply is very important in the feed production process. Based on the combustible and explosive properties of the fuel gas, the fuel gas is safely stored and transported, so that the fuel gas supply system and the feed factory are kept at a safe distance. The existing gas supply system has the advantages that data such as pressure, temperature and flow are mainly measured through a traditional analog meter, and the traditional analog meter does not have a communication function, so that workers need to observe and measure on site, and the manual work is consumed, and meanwhile errors are prone to occurring. Meanwhile, the mode cannot control and supervise the condition of the fuel gas supply system in real time, so that the feed production is often influenced due to insufficient fuel gas supply.
In order to solve this problem, a conventional gas supply management system transmits information such as a liquid level, a pressure, a temperature, a flow rate, and a leakage point of gas in a device of a gas supply system to a cloud platform server by wireless transmission using various sensors mounted on the gas supply system. The staff only need just can realize the remote management and control of gas supply through the intelligent terminal with cloud platform server communication connection. However, since the various sensors come from different manufacturers and the respective communication protocols followed by the sensors are not consistent, the method generally has the problem of poor docking between the various sensors and the cloud platform server.

In order to solve at least the above problems, the present invention proposes a gas supply management system. Various sensors installed on a fuel gas supply system are in butt joint through a preset serial port communication protocol, and data information acquired by the various sensors is acquired. And then the data information is transmitted to the server through a preset wireless communication protocol, so that the real-time transmission of the gas operation data of the industrial field to the server can be flexibly realized. Meanwhile, the server can analyze the data according to the gas operation data, and then gives a management instruction so as to carry out reasonable and timely allocation on the gas.

However, it will be understood by those of ordinary skill in the art that the embodiments described herein may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the embodiments described herein. Moreover, this description is not to be taken as limiting the scope of the embodiments described herein.
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Fig. 1 is a block diagram illustrating a gas supply management system 100 according to an embodiment of the present invention. Fig. 2 is a diagram illustrating a connection relationship between the data collection module 120 and the first data collection module 110 according to an embodiment of the present invention. The gas supply management system 100 and the data collection module 120 of the present invention will be described in detail with reference to fig. 1 and 2.
As shown in fig. 1, the present invention provides a gas supply management system including: a first data acquisition module 110, a data collection module 120, a data terminal module 130 and a server 140. In one embodiment, the first data collection module 110 may include various smart meters and sensors, such as a liquid level sensor, a pressure sensor, a temperature sensor, and a gas flow sensor (e.g., a gas meter), disposed on the first gas-fired device for measuring the first operating data of the first gas-fired device. Wherein the first gas plant may include a gas tank (e.g., a liquefied natural gas tank and a compressed natural gas tank), a gas pipeline, and the like. Meanwhile, the first operation data may include data such as pressure and temperature in the gas tank, a flow rate of gas consumption, whether the gas pipe is leaked, and a leakage point.
In one implementation scenario, the data collection module 120 may be a data collection board, which is generally connected to the various smart meters and sensors (because the various smart meters and sensors are in wired communication, and do not support wireless communication) via RS485 (a serial communication protocol) communication cables, and collects the RS485 communication cables connected between the data collection board and the various smart meters and sensors into an electrical box of the data collection board. In practical operation, since Modbus (Modbus communication protocol, which can be used for serial port communication) has become an industry standard of communication protocol in the industrial field, it is now a common connection method between industrial electronic devices. Therefore, the communication protocols of the various intelligent instruments and sensors are based on the Modbus, but the protocols of the devices of different manufacturers are different, namely, the protocols are obtained by personalized editing on the basis of the Modbus. Therefore, in an embodiment, the data collection module 120 further includes chips compatible with different communication protocols, and the real-time collection of the first operation data detected by the various smart meters and sensors can be realized only by configuring corresponding preset serial port communication protocols (for example, Modbus _ rtu protocol based on RS485 standard) compatible with the communication protocols of the various smart meters and sensors in a configuration.
As shown in fig. 2, the data collection module 120 is connected to the first data collection module 110 (the various smart meters and the sensors) through a switching value collection circuit 133, so as to collect first switching data (i.e., switching states of the various smart meters and the sensors) of the first data collection module 110. In one embodiment, the data collection module 120 may further be connected to the first data collection module 110 according to a preset serial communication protocol 134 (for example, Modbs _ RTU protocol, RTU: Remote Terminal Unit, Remote Terminal device) so as to collect the first parameter data detected by the first data collection module 110 (for example, the pressure and temperature in the gas tank, the flow rate of gas consumption, whether the gas pipeline is leaked, the leakage point, and the like detected by the various smart meters and sensors). Since the first gas appliance includes a plurality of gas cartridges arranged at different positions, first operation data of the gas cartridges at the different positions may be collected through different data collection boards, respectively, for convenience of wiring. The first switching data and the first parameter data both belong to the first operating data.
While the gas supply management system 100 and the data collection module 120 of the present invention have been described above with reference to fig. 1 and 2, it should be understood by those skilled in the art that the framework of the gas supply management system 100 shown in fig. 1 is exemplary and not limiting, and can be adapted as desired by those skilled in the art. Fig. 3 is a block diagram illustrating the data terminal module 130 according to an embodiment of the present invention. The data terminal module 130 of the embodiment of the present invention is exemplarily described below with reference to fig. 3.
After the data collection board collects the first operation data of the first data collection module 110 as above, the first operation data can be collected to the data terminal module 130 in a wireless transmission manner, so that an RS485 communication line is no longer arranged between the first data collection module 110 and the data terminal module 130. In an application scenario, the data collecting board may transmit the first operation data to the data terminal module 130 in a transparent transmission manner through a Modbs _ rtu protocol via Lora (Long Range Radio, Long-distance Radio, a modulation technique of chirp spread spectrum), and the data collecting boards may be connected to the same data terminal module 130 in this manner. As shown in fig. 3, in one embodiment, the data terminal module 130 may include a first control unit 131 and a second control unit 132 connected to each other. The first control unit 131 is connected to the data collection module 120, so as to receive the first operation data and send the first operation data to the second control unit 132 through serial communication. In an embodiment, the first control unit 131 may be a single chip, and the second control unit 132 may be a chip module of a Linux system, such as an MTK7688 (chip manufactured by allied technologies, ltd), and may run a real-time Linux real-time operating system, and be configured to send the first operating data to the server 140 according to a preset wireless communication Protocol, such as http (Hyper Text Transfer Protocol) Protocol or MQTT (Message queue Telemetry Transport Protocol). Through the above manner, the first operation data collected by the first data collection module 110 is collected through the preset serial port communication protocol, and then the first operation data is sent to the server 140 through the preset wireless communication protocol, so that smooth data transmission can be performed between various sensors and the server 140.
In an embodiment, the first control unit 131 is not only configured to collect the first operation data of the data collection board, but also configured to be connected to a second data collection module through a preset serial communication protocol, so as to collect second operation data of a second gas device. The second gas-fired device differs from the first gas-fired device only in the location of the two. The second gas equipment is near-end equipment relative to the data terminal module, namely, is near to the data terminal module, so that the second gas equipment is near to the first control unit 131, and can be connected through an RS485 communication line. The first gas device is a remote device relative to the data terminal module, that is, is far away from the data terminal module, so that the first gas device is also far away from the first control unit 131 and is inconvenient to connect through the RS485 communication line, and therefore, first operation data of the first gas device needs to be collected through the data collection board through the RS485 communication line, and then the first operation data is sent to the first control unit 131 in a wireless manner.
In one embodiment, the first control unit 131 is connected to the second data acquisition module through the switching value acquisition circuit 133, so as to acquire the second switching data of the second data acquisition module. The second data acquisition module, like the first data acquisition module 110, may include various smart meters and sensors such as a liquid level sensor, a pressure sensor, a temperature sensor, and a gas flow sensor (e.g., a gas meter), which are disposed on the second gas appliance and are used for measuring the second parameter data of the second gas appliance. Meanwhile, the first control unit 131 is connected to the second data acquisition module through a communication cable according to a preset serial communication protocol 134, so as to acquire second parameter data detected by the second data acquisition module. Also, in actual operation, the communication protocols of various intelligent meters and sensors are different protocols based on Modbus. Therefore, in an embodiment, the first control unit 131 may further include a preset serial communication protocol 134 for being compatible with different communication protocols, and only the corresponding communication protocol needs to be configured in the configuration, so as to realize real-time collection of the second parameter data detected by the various smart meters and sensors. In one embodiment, the second operating data includes second switching data and second parameter data. The first control unit 131 may be a single chip, where the switching value acquisition circuit 133 and the preset serial communication protocol 134 both operate with the single chip as a carrier.
The second operation data acquired by the first control unit 131 is also transmitted to the second control unit 132 through serial port communication, and the second control unit 132 may send the second operation data to the server 140 according to a preset wireless communication protocol (for example, a network protocol such as an http protocol or an MQTT protocol). Through the above manner, the second operation data collected by the second data collection module is collected through the preset serial port communication protocol, and then the second operation data is sent to the server 140 through the preset wireless communication protocol. At this time, the server 140 generates a management instruction based on the first operation data and the second operation data. In an application scenario, after receiving the first operation data and the second operation data, the first control unit 131 stores the first operation data and the second operation data in the data terminal module 130 in real time. The data is then uploaded to the server 140 via a network protocol such as http protocol or MQTT protocol, and the time interval for transmitting the data to the server 140 may be 15s in order to reduce the stress on the server 140.
After receiving the first operating data and the second operating data, the server 140 analyzes the key real-time parameters of the gas tanks to obtain the real-time production status of each gas tank. And the information such as the storage amount and the consumption rate of the fuel gas in the fuel gas supply system is calculated and analyzed, and finally the time and the supply amount of the fuel gas can be obtained. In addition, the server 140 can also automatically calculate and generate daily report records, weekly report records, monthly report records and the like, so that the staff can conveniently check the records at any time and any place, and the remote real-time control of the gas supply system is realized. In addition, the running conditions and energy consumption conditions of the plant and other plants can be analyzed, so that analysis and comparison among different plants are facilitated, and the tracing of the root cause of the problem is assisted. It is easily understood that the communication among the first data collection module 110, the data collection module 120, the data terminal module 130 and the server 140 is bidirectional, that is, the server 140 can not only obtain the data detected by the first data collection module 110, but also control the operation of the data terminal module 130, the data collection module 120 and the first data collection module 110. The first control unit 131 may be a single chip microcomputer, which is mainly used for integrating data, but cannot remotely manage the single chip microcomputer through an intelligent terminal device. Therefore, the second control unit 132(MTK7688) is connected to the server, so that the worker can perform operations such as remote management, program upgrading and abnormal problem handling on the second control unit 132 through an intelligent terminal device (e.g., a computer), which is beneficial to improving the working efficiency.
While the data terminal module 130 of the embodiment of the present invention has been described with reference to fig. 3, it should be understood by those skilled in the art that the structure of the data terminal module 130 shown in fig. 3 is exemplary and not limiting, and may be modified as needed by those skilled in the art. Fig. 4 is an operational flow diagram 400 illustrating a gas supply management system according to an embodiment of the present invention. The work flow of the gas supply management system of the embodiment of the invention is exemplarily described below with reference to fig. 4.
As shown in fig. 4, at step S401, the server 140 issues a collection instruction, and the switching value collection circuit 133 also detects whether the switches of the first data collection module 110 and the second data collection module are open (i.e., obtains the first switch data and the second switch data). If not, the server 140 will remotely turn on the switches of the first data acquisition module 110 and the second data acquisition module, or notify the staff to go to the field to turn on the switches. In step S402, after the acquisition instruction is transmitted to the first data acquisition module 110 and the second data acquisition module, the first data acquisition module 110 and the second data acquisition module start to detect and feed back the detected data (the first parameter data and the second parameter data) to the server 140 in real time. At step S403, the server 140 analyzes the first and second operation data obtained by the server to obtain information such as the remaining amount of gas in the gas supply system, the pressure and temperature in the gas tank, and the gas consumption rate. At step S404, the server 140 determines whether an abnormal condition occurs according to the analysis result, and if so, the process proceeds to step S406, i.e., cuts off the gas source, and then proceeds to step S407, and issues an alarm, such as a gas station leakage alarm or a boiler gas leakage alarm, according to the analysis result. If there is no abnormal condition, step S405 is proceeded to generate a statistical report according to the requirement of the staff, so that the staff can check the report at any time.
In actual operation, as long as the traditional instrument that arranges in the gas feed system is changed into intelligent instrument or the sensor that can have networking function, then is connected intelligent instrument and sensor through RS485 communication line and data collection board to collect data collection board in the case with the one end of RS485 communication line. And then, the intelligent instrument and the sensor are set by communication protocols, so that the intelligent instrument and the sensor can communicate with the data collection board, and the first operation data and the second operation data measured by the intelligent instrument and the sensor can be transmitted to the data collection board. The original use effect of the fuel gas supply system cannot be damaged in the whole process. It is understood that the data terminal module 130 needs to be installed in a place having a network environment in order to acquire data of the data collection board in a wireless manner.
After receiving the real-time data of the gas supply system (mainly, the gas tank) from the data terminal module 130, the server 140 performs data analysis according to the preset processing logic and algorithm therein, and finally analyzes the current state of the gas tank and the gas surplus, thereby monitoring the gas surplus information and the current use state in the gas tank. If the gas surplus in the gas tank is insufficient, the gas tank automatically contacts a gas supplier through modes of short messages and the like, and the gas supplier is informed of supplying gas in time, so that the effect of intelligent gas dispatching is achieved. If abnormal conditions such as gas leakage occur, the abnormal conditions such as gas leakage points are automatically informed to workers nearby the gas tank through short messages and the like, so that leakage is prevented in time, and greater risks are prevented. Meanwhile, the staff can inquire the real-time data on the corresponding cloud platform and check the automatically generated gas tank operation state and the real-time data.
The technical scheme of the invention can realize the interconversion of various network protocols such as a Modbus _ rtu protocol and an http protocol, and greatly increases the universality of the intelligent instrument and various sensors. The function that different intelligent instruments and sensors can transmit data to the server 140 in real time is achieved. Meanwhile, the operation data of the gas equipment does not need to be recorded on site by workers, and part of labor force is liberated. In addition, the biological safety risk caused by personnel intervention is avoided. Furthermore, the system is convenient for gas suppliers to supply, operate, maintain and manage, and inquire and monitor the operating parameters and states of the gas equipment in multiple factories in the whole area in real time, so that the system can carry out reasonable scheduling, gas resource distribution and effective management, improve the service quality of the suppliers and achieve safer, more timely and efficient service for production.
