Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and in particular to a synchronous signal transmission module and an energy storage converter. Background Technology

[0002] In an energy storage converter system, multiple power conversion systems (PCS) are typically included. These PCS control the charging and discharging process of the battery, converting AC to DC power, and can also directly supply power to AC loads in the absence of a power grid. When the power conversion systems are connected in parallel, the corresponding I / O interfaces of a digital signal processing (DSP) chip are needed to alternately synchronize the signals of the insulated-gate bipolar transistors (IGBTs) under the power conversion systems.

[0003] Typically, a DSP includes one receive I / O port and one transmit I / O port. Taking any energy storage converter in an energy storage converter system as an example, when the energy storage converter is in master mode, it needs to output a synchronization signal through the transmit I / O port, and the receive I / O port does not receive signals at this time; when the energy storage converter is in slave mode, it receives the synchronization signal through the receive I / O port, and the transmit I / O port does not transmit signals at this time.

[0004] The aforementioned transmission method, which involves alternating operation of the corresponding I / O interfaces, leads to a waste of DSP hardware resources. Furthermore, since the transmission of synchronization signals is often implemented through a CAN chip—for example, by converting the TTL signal corresponding to the synchronization signal into a differential signal using a CAN chip—this method significantly increases the receiving and / or transmitting delays.

[0005] Therefore, there is an urgent need for a synchronous signal transmission scheme that can reduce reception and / or transmission delays while saving DSP hardware resources. Utility Model Content

[0047] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0048] As described in the background section, existing technologies suffer from wasted DSP hardware resources. Furthermore, the transmission of synchronization signals relies on the CAN bus, resulting in significant delays in receiving and / or transmitting, and the CAN bus driving capability is limited.

[0049] Based on this, the present invention provides a synchronous signal transmission scheme that can save DSP hardware resources, reduce receiving and / or transmitting delays, and increase driving capability.

[0050] Firstly, please refer to Figure 1 , Figure 1 The diagram shows the module structure of the synchronization signal transmission module in this embodiment. The synchronization signal transmission module 100 is applied to an energy storage converter and includes at least a processing unit 101 and a switching unit 102. The processing unit 101 includes an input / output port. The switching unit 102 is electrically connected to the processing unit 101 through the input / output port of the processing unit 101. The processing unit 101 is also connected to the control terminal of the switching unit 102.

[0051] The switching unit includes multiple operating states, each corresponding to a different signal transmission path.

[0052] The processing unit is used to send different control signals to the control terminal of the switching unit to adjust the working state of the switching unit so that when the energy storage converter is in the master state, it can send a synchronization signal to the outside through the corresponding signal transmission path; and / or so that when the energy storage converter is in the slave state, it can receive external signal transmission through the corresponding signal transmission path.

[0053] In this embodiment, the synchronization signal transmission module utilizes one port of the processing unit to achieve master-slave synchronization signal transmission and reception, saving hardware resources. Specifically, the processing unit sends control signals to the switching unit to adjust its operating state, thereby enabling the transmission of synchronization signals externally through the corresponding signal transmission path when the energy storage converter is in master mode; and / or the reception of external signal transmission through the corresponding signal transmission path when the energy storage converter is in slave mode. This replaces the CAN chip in existing technologies, reducing reception and / or transmission delays.

[0054] In this embodiment, the processing unit can be a digital signal processing chip (DSP). The DSP has an input / output port, which replaces at least one receive I / O port and one transmit I / O port in the original scheme. With the working state of the corresponding switching unit, the DSP realizes the transmission and reception of the master and slave synchronization signals using only one port.

[0055] This embodiment does not limit the module structure of the corresponding switching unit, which can be implemented by a conversion chip or other solutions.

[0056] In one possible implementation method, please Figure 1 Based on, refer to Figure 2 , Figure 2 The diagram shows the module structure of the switching unit in this embodiment. The switching unit 102 includes an analog component 201, the control terminal of which is connected to the processing unit 101; the analog component includes at least two different transmission paths.

[0057] When the analog component includes a first signal transmission path and a second signal transmission path, under the condition that the energy storage converter is in the host state, the processing unit 101 sends a first control command to the analog component 201, and the analog component 201 is in the first signal transmission path; the processing unit 101 outputs a synchronization signal to the switching unit 102 to send the synchronization signal to the outside through the first signal transmission path.

[0058] And / or when the energy storage converter is in slave mode, the processing unit 101 sends a second control command to the analog component 201, and the analog component 201 is in the second signal transmission path so that external signals are sent to the processing unit through the second signal transmission path.

[0059] In this embodiment, the number of signal transmission paths in the analog component is at least two, so as to complete the synchronous signal transmission of the energy storage converter in master-slave mode respectively. However, it should be noted that this embodiment does not limit the configuration of the signal transmission paths in the analog component.

[0060] In one possible implementation method, please refer to Figure 3 , Figure 3 The diagram shows the module structure of the analog component in this embodiment. The analog component 201 includes multiple analog switches 202, which are connected in stages to form multiple signal transmission paths.

[0061] The processing unit is used to send different control signals to the control terminals of each analog switch to adjust the conduction or cutoff status of the corresponding analog switch, thereby turning on or off the corresponding signal transmission path.

[0062] exist Figure 3 Based on this, please refer to Figure 4 , Figure 4 The module structure diagram of the simulation component in this embodiment is shown; the simulation component 201 includes two simulation switches 202, and for any simulation switch 202, it includes at least a control terminal 202-A, an input terminal 202-B, an output terminal 202-C, and a data transmission / reception terminal 202-D.

[0063] When the energy storage converter is in the host state, the processing unit 101 sends a first control command to the control terminal 202-A of each analog switch 202. The data transmission / reception terminal 202-D of each analog switch 202 and the corresponding output terminal 202-C form a data channel to obtain the first data channel, thereby forming the first signal transmission path.

[0064] When the energy storage converter is in slave mode, the processing unit 101 sends a second control command to the control terminal 202-A of each analog switch 202. The data transmission / reception terminal 202-D of each analog switch 202 and the corresponding input terminal 202-B form a data channel to obtain a second data channel, thereby forming a second signal transmission path.

[0065] To ensure the transmission quality of the synchronization signal, please refer to... Figure 5 , Figure 5 Another module structure diagram of the switching unit in this embodiment is shown; the switching unit 102 includes a plurality of disconnect switches 203, at least one disconnect switch 203 is provided and connected between two adjacent analog switches 202, and the processing unit 101 is also connected to the control terminal of the disconnect switch 203; the disconnect switch 203 includes at least two transmission channels.

[0066] The processing unit 101 is used to send a control signal to the disconnecting switch 203 to switch the transmission channel of the disconnecting switch 203, thereby forming different signal transmission paths with the data channel of the analog component 201.

[0067] In this embodiment, Figure 5 Based on this, please refer to Figure 6 , Figure 6Another module structure diagram of the switching unit in this embodiment is shown. When the analog component 201 includes two analog switches 202, the switching unit 102 includes an isolation switch 203. The isolation switch 203 includes at least a control terminal 203-A, a first input terminal 203-B, a second input terminal 203-C, a first output terminal 203-D, and a second output terminal 203-E.

[0068] When the energy storage converter is in host mode, the processing unit sends a first control command to the control terminal 203-A of the disconnector switch 203. The first input terminal 203-B and the first output terminal 203-D of the analog switch form a first transmission channel to constitute a first signal transmission path. The first signal transmission path consists of the first transmission channel and a first data channel. The first data channel is the data channel formed by the data transmitting / receiving terminal 202-D and the corresponding output terminal 202-C of the analog switch.

[0069] When the energy storage converter is in slave mode, the processing unit sends a second control command to the control terminal 203-A of the disconnector 203. The second input terminal 203-C and the second output terminal 203-E of the analog switch form a second transmission channel to constitute a second signal transmission path. The second signal transmission path consists of the second transmission channel and a second data channel. The second data channel is formed by the data transmitting / receiving terminal 202-D of the analog switch and its corresponding input terminal 202-B.

[0070] In this embodiment, the structural type or implementation method of the analog switch or disconnector switch is not limited; all can be implemented using a switch chip in any possible implementation method. For a clear description of the structure of the corresponding switching unit, please refer to [reference needed]. Figure 7 , Figure 7 The circuit diagram of a switching unit in this embodiment is shown. The switching unit 102 includes an isolating switch and an analog component. The analog component includes two analog switches. Chips U14 and U26 represent analog switches 202, and chip U31 represents analog switch 202.

[0071] When the energy storage converter is in host mode, the synchronization signal is output from the processing unit (e.g., the input / output port of the digital signal processing chip) to the interface of the switching unit. At this time, the processing unit sends the first control command to the switching unit. For example, the EXT_FANL_DR pin of the analog chip U26 can be set to 0. At this time, pins 4 and 3 of the analog chip U26 are connected, pins 5 and 12 of the isolation chip U31 are connected, and pins 3 and 4 of the analog chip U14 are connected. Then the synchronization signal (represented as SYNCO_D signal in the figure) is input from pin 4 of chip U26, flows through pin 3 to pin 5 of the isolation chip U31, flows through pin 12 to pin 3 of the analog chip U14, and is transmitted to the outside of the DSP as the host through pin 4.

[0072] When the energy storage converter is in slave mode, the synchronization signal is output from the processing unit (e.g., the input / output port of the digital signal processing chip) to the interface of the switching unit. At this time, the processing unit sends a second control command to the switching unit. For example, the EXT_FANL_DR pin of the analog chip U26 can be set to 1. At this time, pins 4 and 1 of the analog chip U26 are connected, pins 11 and 6 of the isolation chip U31 are connected, and pins 1 and 4 of the analog chip U14 are connected. Then the synchronization signal (represented as SYNCO_D signal in the figure) is input from pin 4 of the isolation chip U14, flows through pin 1 to pin 11 of the isolation chip U31, flows through pin 6 to pin 1 of the analog chip U26, and then through pin 4 to the processing unit (e.g., the input / output port of the digital signal processing chip), thereby realizing the DSP's function of receiving external signals.

[0073] To improve the control efficiency of the processing unit, the processing unit can integrate a digital signal processing (DSP) chip, and the control part of the switching unit can be a field-programmable gate array (FPGA). The FPGA then receives control commands sent by the processing unit and switches the operating state of the switching unit according to the control commands. Simultaneously, to improve the transmission latency of control commands, in this embodiment, the processing unit is connected to the control terminal of the switching unit through a serial peripheral interface. In one possible implementation, a serial peripheral interface (SPI) can be used to send control commands.

[0074] In this embodiment, when the energy storage converter is in host mode, the synchronization signal flows into a 1µs width synchronization signal through pin 3 of the analog chip U14, and outputs a 3.3V pulse width signal through pin 4 of U14. If signal interference exists, the 3.3V pulse width signal will fluctuate significantly. To improve signal anti-interference capability, please refer to... Figure 8 , Figure 8 Another module structure diagram of the synchronization signal transmission module in this embodiment is shown. The synchronization signal transmission module 100 further includes an input / output unit 103; the input / output unit 103 is disposed at the output terminal of the switching unit 102 and connected to the output terminal of the switching unit 102. In this embodiment, the input / output unit 103 is used to adjust the driving capability of the switching unit 102.

[0075] In this embodiment, please refer to Figure 9 , Figure 9 The circuit diagram of the input / output unit in this embodiment is shown. The input / output unit 103 includes an adjustable resistor R1. The first end of the adjustable resistor R1 is connected to the output terminal of the switching unit 102; the second end of the adjustable resistor R1 is grounded. By adjusting the resistance value of the adjustable resistor R1, the driving capability of the switching unit can be adjusted. For example, when the 3.3V pulse width signal fluctuates significantly, the resistance value of the adjustable resistor R1 can be reduced to ensure that the total load does not exceed 500mA.

[0076] In summary, this utility model provides a synchronization signal transmission module applied to an energy storage converter. The synchronization signal transmission module includes a processing unit and a switching unit. The processing unit includes an input / output port; the switching unit is electrically connected to the processing unit through the input / output port; the processing unit is also connected to the control terminal of the switching unit.
