[0036] The detection device and system for carrier communication of a type-II collector according to an embodiment of the present invention will be described below with reference to the drawings.

[0037] Figure 1 It is a schematic structural diagram of a detection device for carrier communication of a type-II collector according to an embodiment of the present invention. As Figure 1As shown, in some embodiments, the detection device 100 for carrier communication of the type-II collector may include: an interface board 1 and M type-II collector bottom boards 2, where M is a positive integer. Among them, the interface board 1 includes M groups of type-II collector bottom board interfaces 11, and the M groups of type-II collector bottom board interfaces 11 correspond to the M type-II collector bottom boards 2 one by one. The interface board 1 is used to establish a first power supply connection and a carrier communication connection with the corresponding type-II collector bottom board 2 through the type-II collector bottom board interface 11. The type-II collector bottom board 2 includes an interface board interface 21, a sampling circuit 22, a metering circuit 23, a microprocessor 24, and N groups of type-II collector interfaces 25. The interface board interface 21 is respectively connected to a corresponding group of type-II collector bottom board interfaces 11 and the sampling circuit 22. Each group of type-II collector interfaces 25 is respectively connected to the microprocessor 24 and the sampling circuit 22, and is used to connect to the type-II collector to be measured to establish a first power supply connection and a carrier communication connection with the type-II collector to be measured. Among them, the sampling circuit 22 is used to sample the electrical signals of the type-II collector to be measured through the first power supply connection and the carrier communication connection. The metering circuit 23 is used to perform electrical energy metering according to the sampled electrical signals and transmit the electrical energy metering result to the microprocessor 24. The microprocessor 24 is used to store the electrical energy metering result, and N is a positive integer. Among them, the number of the type-II collector bottom board interfaces 11 and the type-II collector interfaces 25 can be selected according to the actual situation or specific application, and no specific limitation is made in the embodiments of the present invention. As an example, when M is 4 and N is 5, that is, each interface board 1 includes 4 groups of type-II collector bottom board interfaces 11 and can be connected to 4 type-II collector bottom boards. Each type-II collector bottom board includes 5 groups of type-II collector interfaces 25 and can be connected to 5 type-II collectors to be measured. Then, the device can support the detection of up to 20 type-II collectors at most, realizing the large-scale detection of the carrier communication of the type-II collectors.

[0038] Specifically, the interface board 1 establishes a first power supply connection and a carrier communication connection with the corresponding II - mining floor board 2 through the one - to - one correspondence between the included M groups of II - mining floor board interfaces 11 and M II - mining floor boards 2, so as to supply power to the II - mining floor board 2 and transmit carrier communication signals. The II - type collector interface 25 of the II - mining floor board 2 can be used to connect the II - type collector to be measured. At the same time, through the separate connections of the II - type collector interface 25 with the microprocessor 24 and the sampling circuit 22, a first power supply connection and a carrier communication connection between the II - type collector interface 25 and the II - type collector to be measured are realized, so that the sampling circuit 22 can sample the electrical signals of the II - type collector to be measured. At the same time, the II - mining floor board 2 also includes a metering circuit 23. The metering circuit 23 measures the electrical energy of the sampled electrical signals through the connection with the sampling circuit 22, transmits the electrical energy measurement result to the microprocessor 24 through the connection with the microprocessor 24, and processes the electrical energy measurement result through the calculation software in the microprocessor 24 and stores it in the required format, which is convenient for subsequent access to the data stored in the microprocessor 24 through the corresponding communication protocol when there is an access requirement.

[0039] Exemplarily, the sampling circuit 22 can be used to collect the voltage and current of the power supply of the II - type collector to be measured. The connected metering circuit 23 can calculate power consumption data such as active power and reactive power of the collected voltage and current to obtain the electrical energy measurement result, and realize the functional test of the II - type collector to be measured under various working conditions.

[0040] Figure 2 It is a schematic structural diagram of a detection device for II - type collector carrier communication according to the first embodiment of the present invention.

[0041] As Figure 2 shown, in some embodiments of the present invention, the II - mining floor board interface 11 further includes a first DC power supply interface 111, the interface board 1 further includes a second DC power supply interface 112 and a power supply circuit 113, and the interface board interface 21 further includes a third DC power supply interface 211. Among them, the first DC power supply interface 111 is connected to the corresponding third DC power supply interface 211, the second DC power supply interface is used to connect to an external DC power supply, and the power supply circuit 113 is respectively connected to the second DC power supply interface and each first DC power supply interface 111, and is used to realize the power supply of the external DC power supply to the interface board 1 and each II - mining floor board 2.

[0042] Specifically, in this embodiment, the interface board interface 21 includes a third DC power interface 211. The II acquisition bottom board interface 11 on the interface board 1 includes a first DC power interface 111. In addition to the II acquisition bottom board interface 11 on the interface board 1, there are also a second DC power interface 112 and a power supply circuit 113. The second DC power interface is connected to an external DC power supply. The first DC power interface 111 is connected to the corresponding third DC power interface 211. The power supply circuit 113 is respectively connected to the second DC power interface and each first DC power interface 111, so that the external DC power supply can be input to the second DC power interface to supply power to the interface board 1, and then transmitted to the first DC power interface 111 through the power supply circuit 113, and then reach the third DC power interface 211 of the II acquisition bottom board 2, realizing the power supply of the external DC power supply to each II acquisition bottom board 2.

[0043] Figure 3 It is a schematic structural diagram of the detection device for the carrier communication of the type-II collector in the second embodiment of the present invention.

[0044] As Figure 3 shown, in some embodiments of the present invention, the II acquisition bottom board interface 11 includes a first 220V carrier interface 115, and the first 220V carrier interface 115 is used to establish a first power supply connection and a carrier communication connection with the corresponding II acquisition bottom board 2; the interface board 1 further includes a second 220V carrier interface 114, and the second 220V carrier interface 114 is respectively connected to each first 220V carrier interface 115 and is used to connect an external 220V carrier device; wherein, the type-II collector interface 25 includes a third 220V carrier interface 212, and the sampling circuit 22 is respectively connected to each third 220V carrier interface 212 and the first 220V carrier interface 115.

[0045] It should be understood that the second 220V carrier interface 114 is used to connect an external 220V carrier device. Therefore, the second 220V carrier interface 114 can be connected to each first 220V carrier interface 115 through a 220V power line. Since the 220V power line itself has a carrier communication function, the connection between the second 220V carrier interface 114 and each first 220V carrier interface 115 through the 220V power line can realize the transmission of the carrier communication signal in the interface board 1.

[0046] Specifically, the second 220V carrier interface 114 provided on the interface board 1 is connected to an external 220V carrier device, and the second 220V carrier interface 114 is respectively connected to each first 220V carrier interface 115, so that the 220V carrier communication signal can be transmitted to each first 220V carrier interface 115 through the second 220V carrier interface 114. Since the sampling circuit 22 is respectively connected to the first 220V carrier interface 115 and each third 220V carrier interface 212 in the II sampling bottom board 2, the carrier signal can be transmitted between each II sampling bottom board 2 and the interface board 1.

[0047] Further, as Figure 3 shown, in this embodiment, the interface board 1 further includes a radio frequency coupling circuit 116 and a radio frequency interface 117. The radio frequency interface 117 is used to connect to an external radio frequency device. The radio frequency coupling circuit 116 is respectively connected to the radio frequency interface 117, the second 220V carrier interface 114, and each first 220V carrier interface 115, and is used to separate the carrier signal from the common line of the first power supply connection and the carrier communication connection and transmit it to the external radio frequency device.

[0048] Specifically, since the radio frequency coupling circuit 116 is connected to the second 220V carrier interface 114 and each first 220V carrier interface 115, the radio frequency coupling circuit 116 can separate the carrier signal in the common line of the first power supply connection and the carrier communication connection, and through the connection between the radio frequency coupling circuit 116 and the radio frequency interface 117, transmit the carrier signal to the external radio frequency device through the radio frequency interface 117. Optionally, if the external radio frequency device is a radio frequency signal generator, the carrier signal separated through the above implementation process can be injected into the channel as analog noise. If the external radio frequency device is a spectrum analyzer, the spectrum analyzer can be used to analyze the radio frequency signal spectrum. In some embodiments, the radio frequency interface 117 can also be connected to the radio frequency interface 117 of other detection devices for carrier communication of type II collectors, so as to realize the interconnection between different detection devices.

[0049] Further, as Figure 3 shown, in this embodiment, the type II collector interface 25 further includes an RS-485 interface 213 to establish RS-485 communication with the type II collector to be measured. The II sampling bottom board 2 further includes N RS-485 interface circuits 26. The N RS-485 interface circuits 26 correspond to the N RS-485 interfaces 213 one by one. The RS-485 interface circuits are respectively connected to the corresponding RS-485 interfaces 213 and the microprocessor 24. Among them, the microprocessor 24 also configures the type II collector to be measured and the virtual watt-hour meter connected thereto through RS-485 communication connection.

[0050] Specifically, an RS-485 communication connection is established between the detection device 100 for the II-type collector carrier communication and the II-type collector to be measured through the RS-485 interface 213 included in the II-type collector interface 25. Also, through the connection of the RS-485 interface circuit 26 to the corresponding RS-485 interface 213 and the microprocessor 24 respectively, the microprocessor 24 can configure the II-type collector to be measured that is communicatively connected to the RS-485 interface 213 through the RS-485 communication connection. Since the electric energy meter can be connected to the II-type collector to be measured through the RS-485 bus, in some embodiments, the microprocessor 24 can also configure the electric energy meter connected to the II-type collector to be measured through the RS-485 communication connection. Optionally, according to the national grid technical specifications, a II-type collector can support up to 32 virtual electric energy meters at most. Therefore, the number of electric energy meters connected to the II-type collector to be measured in this embodiment can be selected according to the actual situation, and no specific limitation is made in the embodiments of the present invention. When there is a large-scale detection requirement, the detection device 100 for the II-type collector carrier communication is small in volume and light in weight, reducing the occupied space and achievable cost.

[0051] It should be noted that, for the sake of clarity, only one sampling circuit 22 and RS-485 interface circuit 26 related to the II-type collector interface 25 in one path of the II-type collector baseboard 2 are drawn in the figures shown in the embodiments of the present invention. The connection methods of the other paths are the same as this path, and the structures of other II-type collector baseboards are the same as this II-type collector baseboard.

[0052] Furthermore, as Figure 3 shown, the II-type collector baseboard interface 11 further includes a first Ethernet interface 119. The interface board 1 further includes a second Ethernet interface 118 and a switch circuit 120. The interface board interface 21 further includes a third Ethernet interface 214. The first Ethernet interface 119 is respectively connected to the microprocessor 24 and the corresponding third Ethernet interface 214. The switch circuit 120 is respectively connected to each first Ethernet interface 119 and the second Ethernet interface 118. The second Ethernet interface 118 is used to connect to an external computer to establish an Ethernet connection between the external computer and each microprocessor 24, so as to realize visual display of the electric energy measurement results through the external computer and configure the II-type collector to be measured and the virtual electric energy meters connected thereto.

[0053] Specifically, since the switch circuit 120 can be respectively connected to each first Ethernet interface 119 and the second Ethernet interface 118, and the second Ethernet interface 118 can be connected to an external computer, and the first Ethernet interface 119 is respectively connected to the microprocessor 24 and the corresponding third Ethernet interface 214, an Ethernet connection can be established between the external computer and the microprocessors 24 in each II acquisition board 2, enabling devices such as the external computer to access each II acquisition board 2 through Ethernet and configure the II-type collector under test and the virtual watt-hour meters connected thereto. In some embodiments, the measurement results of the measurement circuit 23 can also be visually displayed through an external computer, such as the power consumption data acquisition situation, detection items, detection logs, and detection processes of the II-type collector under test. In practical applications, corresponding host computer software can be run on the external computer according to specific requirements, and no specific limitations are made in the embodiments of the present invention.

[0054] Exemplarily, configuring the II-type collector under test and the virtual watt-hour meters connected thereto through an external computer may include: separately controlling the power supply of each II acquisition board 2, separately configuring the baud rate parameters of the RS-485 interfaces 213 in each II acquisition board 2, etc., and the specific configuration can be selected according to actual requirements.

[0055] In this embodiment, the microprocessor 24 can also be used to transmit the acquisition data of the watt-hour meter connected to the II-type collector under test to an external computer.

[0056] It can be understood that since the first Ethernet interface 119 is respectively connected to the microprocessor 24 and the corresponding third Ethernet interface 214, and since the microprocessor 24 is connected to the II-type collector under test through the RS-485 interface circuit 26 and the corresponding RS-485 interface 213, the microprocessor 24 can transmit the acquisition data of the watt-hour meter connected to the II-type collector under test to the first Ethernet interface 119 through the third Ethernet interface 214, and then transmit it to the second Ethernet interface 118 through the switch circuit 120. Therefore, through the connection between the second Ethernet interface 118 and the external computer, the acquisition data of the watt-hour meter connected to the II-type collector under test can be transmitted to the external computer, and when relevant personnel need to view the acquisition data of the watt-hour meter, the data can be visually displayed.

[0057] Figure 4 It is a schematic structural diagram of a detection device for II-type collector carrier communication according to a specific embodiment of the present invention.

[0058] As a feasible implementation manner, such as Figure 4As shown in the figure, the microprocessor 24 includes a configuration unit 241, a power consumption analysis unit 242, and a communication unit 243. The communication unit 243 is connected to the third Ethernet interface 214. The configuration unit 241 is respectively connected to the communication unit 243 and each RS-485 interface 213, and is used to implement the configuration of virtual electricity meters by an external computer, data transparent transmission configuration, and power supply control of the type-II collector under test. The power consumption analysis unit 242 is respectively connected to the communication unit 243 and the metering circuit 23, and is used to perform power consumption analysis based on the electricity metering results and transmit the power consumption analysis results to the external computer. Among them, the configuration of the virtual electricity meter includes the communication protocol configuration, communication address configuration, electricity meter data configuration, and electricity meter event configuration of the virtual electricity meter.

[0059] It can be understood that for each type-II collector under test, 1 to 32 virtual electricity meters can be supported for configuration. For each virtual electricity meter, it is supported to configure various parameters and functions through an external computer, such as configuring the communication protocol, communication address, electricity meter data, electricity meter event, etc. of each virtual electricity meter, so as to support simulating very complex type-II collector application scenarios, that is, realizing the flexible configuration of the type-II collector simulation detection environment. At the same time, since each virtual electricity meter can include the simulation of functions and data such as communication protocol, communication address, electricity meter data, and electricity meter event, it can meet all aspects of requirements for the electricity meter during simulation detection and ensure the reliability of the detection results.

[0060] Optionally, the configuration unit 241 is used to, when receiving the meter search instruction issued by the type-II collector under test, feedback the communication addresses of each virtual electricity meter to the type-II collector under test; and when receiving the electricity meter data read or write instruction issued by the type-II collector under test, feedback the data of the virtual electricity meter corresponding to the communication address in the electricity meter data read or write instruction to the type-II collector under test, so as to realize the read and write operations of the type-II collector under test on the corresponding virtual electricity meter data.

[0061] It should be understood that each virtual electricity meter can use different communication protocols, such as industry standard protocols like DL / T 645-1997, DL / T 645-2007, DL / T 698.45-2017, etc., and supports protocol extension. At the same time, each virtual electricity meter has a different communication address. During the process of the Type-II collector under test searching for meters, each virtual electricity meter in the microprocessor 24 can receive the meter search instruction from the Type-II collector under test and respond with its own communication address. Also, since each virtual electricity meter maintains a set of electricity meter data, when the Type-II collector under test requests to issue an electricity meter read or write instruction through the RS-485 interface 213, that is, requests to read or write electricity meter data, the virtual electricity meter that matches the address in the read or write instruction can make a response. The configuration unit 241 feeds back the data of the virtual electricity meter corresponding to the communication address in the electricity meter data read or write instruction to the Type-II collector under test, realizing the read and write operations of the virtual electricity meter data. In some embodiments, because each virtual electricity meter maintains a set of electricity meter events, during the event reporting process of the Type-II collector under test, the Type-II collector under test can also collect the event data of each virtual electricity meter and report them respectively.

[0062] For the detection device of Type-II collector carrier communication according to an embodiment of the present invention, when conducting large-scale detection of Type-II collector carrier communication, the detection device of Type-II collector carrier communication is small in volume and light in weight, reducing the occupied space and achievable cost.
