[0066] In the embodiment, the data processing device is connected with the communication module of the fuel dispenser and the communication module of the liquid level meter respectively to analyze the raw data of the fuel dispenser and the liquid level meter, and obtain the operation data of the fuel dispenser and the tank data of the liquid level meter respectively. Specifically, the data processing device can be divided into a fuel dispenser data processing module and a liquid level meter data processing module, which can correspondingly receive the raw data of the fuel dispenser and the liquid level meter respectively, and analyze the raw data based on the communication protocol in the respective data processing modules to obtain the respective data results.

[0068] Specifically, in the above embodiment, as shown in Figure 4As shown, the fuel dispenser data processing module includes a data acquisition unit, a control unit and a communication unit, wherein the data acquisition unit is connected with the communication module of the fuel dispenser, and is configured to acquire the original data sent by the fuel dispenser; the control unit is connected with the data acquisition unit, and is configured to determine the fuel dispenser analysis protocol corresponding to the model of the fuel dispenser according to the pre-configured model of the fuel dispenser, and analyze the original data based on the fuel dispenser analysis protocol to obtain the operation data of the fuel dispenser; the communication unit is connected with the control unit, and is connected with the hub or is communicatively connected with the data receiving platform through a network, and is configured to send the operation data to the hub or the data receiving platform.

[0069] In the embodiment, one or more oil guns are connected with each fuel dispenser, and the original data sent by the fuel dispenser includes the operation state information of each oil gun connected with the fuel dispenser and the operation state information of the fuel dispenser itself. The data acquisition unit can accurately acquire the original data sent by the fuel dispenser. The control unit is connected with the data acquisition unit, so that the data acquisition unit can determine the data analysis protocol corresponding to each fuel dispenser according to the pre-configured model of the fuel dispenser, and analyze the original data sent by the fuel dispenser based on the data analysis protocol corresponding to the fuel dispenser to obtain the operation data of each fuel dispenser. When the models of at least one fuel dispenser connected are the same, the same set of communication protocols can be used to analyze the original data in each fuel dispenser one by one. When the models of the fuel dispensers connected are different, the original data in each fuel dispenser needs to be analyzed according to the communication protocol corresponding to each fuel dispenser to obtain the operation data corresponding to each fuel dispenser. The communication unit is configured to send the obtained operation data of the fuel dispenser to the data receiving platform directly to realize timely uploading of data. The operation data of the fuel dispenser can also be sent to the hub first, and then transmitted to the data receiving platform or other communication equipment through the hub, which has strong flexibility.

[0070] Specifically, in the above embodiment, as shown in the figure, Figure 5 As shown, the liquid level meter data processing module includes a serial communication unit, a data processing unit and a data transmission unit, wherein the serial communication unit is connected with the communication module of the liquid level meter, and is configured to acquire the original data sent by the liquid level meter; the data processing unit is connected with the serial communication unit, and is configured to determine the liquid level meter analysis protocol corresponding to the model of the liquid level meter according to the pre-configured model of the liquid level meter, and analyze the original data based on the liquid level meter analysis protocol to obtain the tank data of the liquid level meter; the network communication module is connected with the data processing unit, and is connected with the hub or is communicatively connected with the data receiving platform through a network, and is configured to send the tank data to the hub or the data receiving platform; and the hub is configured to send the received operation data of the fuel dispenser and the tank data of the liquid level meter to the data receiving platform.

[0071] In the embodiment, the liquid level meter is an instrument for detecting the surface of liquid, flow, and flow rate by using electronic or other technologies, and is applied in a gas station. The liquid level meter is used to detect the relevant data of oil in the oil tank. Specifically, the liquid level meter data processing module can be connected to the communication module of at least one liquid level meter through the serial communication unit, and the original data sent by the connected liquid level meter can be collected by active reception or passive query. After receiving the original data sent by the liquid level meter, the data processing module can further determine the data analysis protocol corresponding to each liquid level meter according to the pre-configured liquid level meter model, and analyze the original data sent by the liquid level meter based on the data analysis protocol corresponding to the liquid level meter to obtain the oil tank data of each liquid level meter. The oil tank data truly reflects the storage condition of the oil in the corresponding oil tank, and the oil tank data includes oil volume, water volume, oil height, water height, temperature, pressure, density, oil inflow, and side leakage, etc. In the process of data analysis of the liquid level meter data processing module, when the models of the connected at least one liquid level meter are the same, the same set of communication protocols can be used to analyze the original data in each liquid level meter one by one, and when the models of the connected liquid level meters are different, the communication protocols of the respective liquid level meters need to be used to analyze the original data in each liquid level meter to obtain the oil tank data corresponding to each liquid level meter. The data transmission unit can be set to enable the liquid level meter data processing module to directly send the analyzed oil tank data to the data receiving platform to realize timely uploading of data, or the oil tank data can be first sent to the concentrator, and then transmitted to the data receiving platform or other communication equipment through the concentrator, which has strong flexibility.

[0072] Specifically, in the above embodiment, the concentrator includes a first data channel, a second data channel, and a third data channel. The first data channel of the concentrator is connected to the gas dispenser data processing unit to receive the running data of the gas dispenser, or the first data channel of the concentrator is connected to the communication module of the gas dispenser to collect the original data sent by the gas dispenser, and analyze the original data of the gas dispenser based on the communication protocol of the gas dispenser to obtain the running data of the gas dispenser. The second data channel of the concentrator is connected to the liquid level meter data processing unit to receive the oil tank data of the liquid level meter, or the second data channel of the concentrator is connected to the communication module of the liquid level meter to collect the original data sent by the liquid level meter, and analyze the original data of the liquid level meter based on the communication protocol of the liquid level meter to obtain the oil tank data of the liquid level meter. The third data channel of the concentrator is connected to the data receiving platform to send the running data of the gas dispenser and / or the oil tank data of the liquid level meter to the data receiving platform.

[0073] In the embodiment, the hub can regenerate, reshape, and amplify the received signal to expand the transmission distance of the network, and all communication nodes in the communication system are concentrated on the node of the hub, which is the basic equipment in the communication system. The hub provided by the application has basic data transmission function, is connected between the communication equipment such as the refueling machine and the liquid level instrument and the data receiving platform, obtains the running data of the refueling machine and the tank data of the liquid level instrument after the original data is analyzed by the refueling machine data processing module and the liquid level instrument data processing module, and directly transmits the data to the data receiving platform for display. On the other hand, considering different application environments, such as Figure 6 As shown in the figure, when the refueling machine and the liquid level instrument are not connected with the corresponding data processing module, the communication module of the refueling machine and the communication module of the liquid level instrument are directly connected with the hub, and the hub itself also has data processing function. After the data channel of the hub is connected with the communication module of the refueling machine or the liquid level instrument, the original data of the communication equipment is received, the corresponding communication protocol of the refueling machine or the liquid level instrument is determined based on the model, the original data is analyzed based on the communication protocol, the data result is obtained, and the obtained data result is transmitted to the data receiving platform through the wired network. After the hub itself is configured with the data processing function, the configuration of the refueling machine data processing module and the liquid level instrument data processing module can be reduced, the data analysis is directly performed through the hub, the data transmission is performed through the wired network, the data transmission stability is better, the independent data processing module is avoided to be unstable in the wireless network fluctuation, and the effect of data transmission is affected.

[0074] Specifically, the channel information of the data acquisition channel of the hub can be configured through an external device, for example, a computer device installed with a configuration tool is connected with the hub through the IP address and the port number of the hub, and then the channel information of each data acquisition channel of the hub is configured through the configuration tool. The first data acquisition channel corresponds to the connection of the refueling machine data processing module or the communication module of the refueling machine, and therefore the channel information of the first data acquisition channel can include the channel number, the protocol number, the communication parameter, the automatic authorization flag, the oil machine log flag, the number of oil guns, the oil gun number, and the oil product code of the first data acquisition channel. The second data acquisition channel corresponds to the connection of the liquid level instrument data processing module or the communication module of the liquid level instrument, and therefore the channel information of the second data acquisition channel can include the channel number, the protocol number, and the communication parameter of the second data acquisition channel. After the configuration tool is configured, the channel information of each data acquisition channel can be issued to the hub through the network. The hub itself has a storage device for data storage, and therefore the hub can save the channel information of each data acquisition channel in the storage device of the hub, which is convenient for subsequent repeated use.

[0075] Specifically, in the above embodiment, asFigure 7 As shown in the figure, the communication interface of the concentrator is connected with a communication conversion module, which includes a serial data receiving interface, a 485 signal transmission interface, a serial data sending interface and a 485 signal transceiver unit. The serial data receiving interface is connected with the data sending interface of the fuel dispenser, and the serial data sending interface is connected with the data receiving interface of the fuel dispenser. The serial data receiving interface and the serial data sending interface are respectively connected with the 485 signal transmission interface through the 485 signal transceiver unit, and the 485 signal interface is connected with the communication interface of the concentrator. The fuel dispenser and the concentrator perform data forwarding through the communication conversion module.

[0076] In the embodiment, some fuel dispensers and other communication devices use the communication mode of three-wire current loop for communication, which leads to poor communication compatibility between the fuel dispensers and serial communication devices supporting other communication modes. Therefore, the communication conversion module is connected with the communication interface of the concentrator to convert the current loop signal into RS485 signal, so that the current loop communication device can communicate with the serial communication device supporting the RS485 signal communication mode. Specifically, the connection relationship between the communication conversion module and the fuel dispenser and the concentrator is as shown in the figure. Figure 8 As shown in the figure, the level signal sent by the current loop communication device such as the fuel dispenser is received through the serial data receiving interface, and then communicated with the concentrator through the 485 signal transmission interface after passing through the 485 signal transceiver unit. The conversion function of the communication conversion is realized by the RS485 chip in the 485 signal transceiver unit for communication signal conversion. In the process of receiving the communication signal, the signal needs to be transmitted to the RS485 chip through the first signal isolation unit and the first voltage level conversion unit. The signal isolation unit and the voltage level conversion unit can effectively improve the stability of signal transmission and ensure the accuracy of signal transmission. Similarly, the differential signal sent by the concentrator is transmitted to the RS485 chip through the 485 signal transmission interface, and then sequentially passes through the second signal isolation unit and the second voltage level conversion unit, and then the level signal is transmitted to the fuel dispenser through the serial data sending interface, so as to realize the half-duplex communication between the fuel dispenser and the concentrator. The setting of the communication conversion module effectively improves the universality and compatibility of the current loop communication device communication.

[0077] Specifically, in the above embodiment, as shown in the figure, Figure 9As shown, the data processing device comprises a display signal processing module, the display signal processing module comprises a display signal acquisition unit, a signal control unit and a signal transmission unit, wherein the display signal acquisition unit is connected with the display signal line of the fuel dispenser, and is used for acquiring the display signal of the fuel dispenser; the signal control unit is connected with the display signal acquisition unit, and is used for determining the signal analysis protocol corresponding to the display signal according to the pre-configured fuel dispenser model, and analyzing the display signal according to the signal analysis protocol to obtain the transaction data and real-time data of the fuel dispenser; the signal transmission unit is connected with the signal control unit, and is connected with the hub or is in communication connection with the data receiving platform through the network, and is used for sending the transaction data and real-time data of the fuel dispenser to the hub or the data receiving platform.

[0078] In the embodiment, there are some relatively old fuel dispenser devices in the gas station that do not support online communication, so the communication protocol of the fuel dispenser cannot be accurately obtained, and therefore the display signal processing module is arranged. Specifically, the connection relationship between the display signal processing module and the fuel dispenser and the hub is as shown in Figure 10 As shown, first, the display signal of the fuel dispenser is acquired, then the signal analysis protocol corresponding to the display signal is determined according to the pre-configured fuel dispenser model, and then the acquired display signal is analyzed according to the signal analysis protocol, so that the transaction data and real-time data of the fuel dispenser can be accurately obtained, and finally the transaction data and real-time data of the fuel dispenser are sent to the hub or the data receiving platform, so that the effective collection of the fuel dispenser data can be realized. By arranging the display signal processing module, a plurality of fuel dispenser devices of different models can be connected, the application range is wide, and the accuracy of the obtained data is high.

[0079] Specifically, in the above embodiment, the data processing device comprises a communication monitoring module, as shown in Figure 11 As shown, the communication monitoring module comprises a data receiving interface, a 485 signal output interface, a 485 signal sending unit, a 232 signal output interface and a 232 signal sending unit, wherein the data receiving interface of the communication monitoring module is connected with the data sending interface of the fuel dispenser and the data receiving interface of the fuel dispenser respectively; the data receiving interface is connected with the 485 signal output interface through the 485 signal sending unit, the 485 signal output interface is connected with the communication interface of the hub, or the data receiving interface is connected with the 232 signal output interface through the 232 signal sending unit, and the 232 signal output interface is connected with the communication interface of the hub; the communication monitoring module is used for monitoring the communication data of the fuel dispenser, and transmitting the communication data of the fuel dispenser to the hub.

[0080] In the embodiment, part of the fuel dispensers in the gas station have been connected with other gas station management systems, but the communication data such as the supported communication protocol and version information cannot be directly obtained, so the communication data of the fuel dispensers is monitored by setting a communication monitoring module without affecting the normal communication process of the fuel dispensers, and the communication data of the fuel dispensers is transmitted to the hub for further analysis. Specifically, the connection relationship between the communication monitoring module, the fuel dispensers and the hub is as shown in Figure 12 The communication monitoring module receives and transmits the signals transmitted in two directions in the normal communication state of the fuel dispensers through the data receiving interface, and transmits the signals to the 232 signal transmitting unit and the 485 signal transmitting unit for processing, and transmits the signals to the hub in the form of RS485 signals or RS232 signals to obtain the communication data of the fuel dispensers. The 485 signal transmitting unit includes two RS485 chips, and the 232 signal transmitting unit includes one RS232 chip, and signal conversion is realized through the respective chips, so that the communication monitoring module supports more communication devices.
