[0045] A shunt is a device used for current detection and is used in various industries. Currently, with the rapid development of some industries, the requirements for shunt detection accuracy are also increasing. However, the shunts currently on the market still have various problems during use, which means that the detection accuracy of the shunts during use does not meet the high precision requirements.

[0046] For example, when a shunt is currently in actual use, the temperatures of the devices connected at both ends of the shunt are different, which can cause a thermoelectric potential difference at both ends of the current sensing resistor in the shunt, thereby affecting the accuracy of the shunt detection.

[0047] In order to solve the above problems, the present invention proposes a diverter. Figure 1 In one embodiment of the present invention, the diverter includes:

[0048] A current sensing element 10 , wherein a first end of the current sensing element 10 is connected to a first conductive element 20 , and a second end of the current sensing element 10 is connected to a second conductive element 30 ;

[0049] a first temperature detection module 40 , the first temperature detection module 40 being disposed near the first end of the current sensing element 10 ; the first temperature detection module 40 being configured to detect the temperature of the first end of the current sensing element 10 and output a corresponding first temperature detection signal;

[0050] The second temperature detection module 50 is arranged near the second end of the current sensing element 10; the second temperature detection module 50 is used to detect the temperature of the second end of the current sensing element 10 and output a corresponding second temperature detection signal.

[0051] Optionally, the current sensing element 10 can be implemented by using at least one current sensing resistor, such as an alloy resistor, such as a manganese-copper alloy resistor. The current sensing element 10 can be directly connected in series in the circuit to be measured by welding; Figure 1 The current sensing element 10 can also be implemented by using at least one current sensing resistor and a conductive member connected to the current sensing resistor. For example, a first conductive member 20 and a second conductive member 30 for conducting electricity and / or fixing to corresponding connection terminals in the circuit to be measured are respectively provided on both sides of an alloy resistor. The first conductive member 20 and the second conductive member 30 can be made of metal materials, such as copper.

[0052] Optionally, the first temperature detection module 40 and the second temperature detection module 50 can be implemented using a temperature detection circuit composed of an NTC resistor / NTC probe and corresponding peripheral circuits, a thermocouple, an infrared temperature sensor, or other temperature detection module. Taking the use of an NTC resistor as an example, a circuit board can be provided within the shunt. The NTC resistor in the first temperature detection module 40 is provided on the circuit board near the first end of the current sensing element 10, and the NTC resistor in the second temperature detection module 50 is provided on the circuit board near the second end of the current sensing element 10. This arrangement not only detects the temperature at both ends of the current sensing element 10, but also, because the first temperature detection module 40 and the second temperature detection module 50 are provided near both ends of the current sensing element 10, the actual temperature at both ends of the current sensing element 10 can be more accurately determined.

[0053] Optionally, refer to Figure 2 In one embodiment, there are multiple first temperature detection modules 40 and / or multiple second temperature detection modules 50. With this configuration, the main control circuit 80 within the external terminal or shunt in the following embodiments can more accurately determine the temperature across the current sensing element 10 based on multiple first temperature detection signals and / or multiple second temperature detection signals, thereby more accurately determining the thermoelectric potential difference across the current sensing element 10.

[0054] Optionally, in one embodiment, the diverter further comprises:

[0055] A communication module, to which the first temperature detection module 40 and the second temperature detection module 50 are both electrically connected; the communication module is used to establish a communication connection with an external terminal;

[0056] The first temperature detection module 40 is configured to output the first temperature detection signal to an external terminal via the communication module;

[0057] The second temperature detection module 50 is configured to output the second temperature detection signal to an external terminal via the communication module;

[0058] In this embodiment, the communication module can optionally be implemented using a wired communication module, such as a CAN communication transceiver, a LIN communication transceiver, or a digital signal interface module with anti-interference capability, such as an ISOSPI communication chip. Alternatively, the communication module can also be implemented using a wireless communication module, such as a Bluetooth communication module, a WIFI communication module, a 4G / 5G communication module, etc. In this way, in actual application, the external terminal can obtain the temperature of the two ends of the current sensing element 10 through the communication module, and then confirm the temperature difference between the two ends of the current sensing element 10, so that the voltage drop can be corrected based on the current voltage drop on the current sensing element 10 (a sampling circuit 70 can be provided in the shunt to collect the voltage drop on the current sensing element 10 and output it through the communication module, or the two ends of the current sensing element 10 are directly electrically connected to the external terminal so that the external terminal can autonomously detect the voltage drop on the current sensing element 10) and the temperature difference. For example, the external terminal pre-stores a temperature difference-thermoelectric potential difference mapping table obtained by R&D personnel based on multiple experiments. The external terminal can then determine the current thermoelectric potential difference based on the temperature difference, and then subtract the thermoelectric potential difference from the current voltage drop to obtain the actual voltage drop, thereby achieving calibrated voltage drop.

[0059] Similarly, optionally, in another embodiment, the output end of the first temperature detection module 40 is used to connect to an external terminal, and the output end of the second temperature detection module 50 is used to connect to an external terminal. The output end of the first temperature detection module 40 and the output end of the second temperature detection module 50 can be an interface or a conductive end. The interface can be a standard interface for connecting to an external terminal. The external terminal can be inserted into the two interfaces or welded / contacted on the two corresponding conductive ends through its own connecting wire to establish an electrical connection path between the external terminal and the first temperature detection module 40 and the second temperature detection module 50, thereby directly obtaining the first temperature detection signal and the second temperature detection signal and performing the same process of calibrating the voltage drop on the current sensing component 10 as mentioned above.

[0060] Optionally, based on the above embodiment in which the first conductive member 20 and the second conductive member 30 are provided at both ends of the current sensing member 10, in one embodiment, referring to Figures 1-4The first end of the current sensing element 10 is connected to the first conductive member 20, and the second end of the current sensing element 10 is connected to the second conductive member 30. The first temperature detection module 40 is disposed on the first conductive member 20 near the first end of the current sensing element 10. And / or the second temperature detection module 50 is disposed on the second conductive member 30 near the second end of the current sensing element 10. This arrangement allows the first temperature detection module 40 and the second temperature detection module 50 to be closer to the ends of the current sensing element 10, thereby further improving the accuracy of their detection of the temperature at both ends of the current sensing element 10.

[0061] Optionally, in another embodiment, the shunt can also automatically calibrate the voltage drop across the current sensing element 10 according to the temperature across the current sensing element 10, and then calculate the actual current value in the circuit to be measured. Figure 5 , the diverter further includes:

[0062] a sampling circuit 70 , the sampling circuit 70 being connected to the first end and the second end of the current sensing element 10 , respectively; the sampling circuit 70 being configured to collect a voltage drop across the current sensing element 10 and output a corresponding voltage drop collection signal;

[0063] A main control circuit 80 is electrically connected to the first temperature detection module 40 , the second temperature detection module 50 and the sampling circuit 70 .

[0064] In this embodiment, the main control circuit 80 can be implemented by a main controller, such as an MCU, a DSP (Digital Signal Process), an FPGA (Field Programmable Gate Array), a PLC, a SOC (System On Chip), etc.

[0065] In this embodiment, optionally, in one embodiment, the sampling circuit 70 includes:

[0066] An analog-to-digital conversion module, the analog-to-digital conversion module is electrically connected to the current sensing element 10, and is used to detect the voltage of at least one end of the current sensing element 10, and output the collected at least one voltage signal to the main control circuit 80 after analog-to-digital conversion; wherein the voltage drop collection signal includes a voltage signal;

[0067] In this embodiment, the analog-to-digital conversion module can be implemented using an ADC (Analog-to-Digital Converter) conversion chip. It is understandable that in actual applications, one end of the current sensing element 10 may be directly electrically connected to the positive terminal or the negative terminal of the power supply of the circuit to be tested. Therefore, at this time, the voltage at the other end of the current sensing element 10 can be collected through the analog-to-digital conversion module, so that the external terminal can finally confirm the actual voltage. Similarly, if both ends of the current sensing element 10 are connected to components in other circuits to be tested, or in order to improve detection accuracy and eliminate the influence of the connection line between one end of the current sensing element 10 and the positive terminal or the negative terminal of the power supply, the voltage at both ends of the current sensing element 10 can be collected through the analog-to-digital conversion module, and the collected voltage signal can be converted into a digital signal and output to the main control circuit 80. The main control circuit 80 can determine the voltage at both ends of the current sensing element 10 based on the result output by the analog-to-digital conversion module, and calculate the voltage drop across the current sensing element 10 by taking the difference between the voltages at both ends.

[0068] Optionally, in another embodiment, the sampling circuit 70 includes:

[0069] a differential amplifier circuit, the differential amplifier circuit being electrically connected to both ends of the current sensing element 10 and configured to differentially amplify the voltage across the current sensing element 10 and output a second voltage signal;

[0070] An analog-to-digital conversion module is electrically connected to the differential amplifier circuit, and is used to output the second voltage signal to the main control circuit 80 after analog-to-digital conversion.

[0071] In this embodiment, the digital-to-digital conversion module can be implemented using the devices described in the above embodiments, and the differential amplifier circuit can be implemented using a differential amplifier. The differential amplifier can directly perform differential amplification on the voltage across the collected current sensing element 10 and output a second voltage signal to the analog-to-digital conversion module, so that the analog-to-digital conversion module performs analog-to-digital conversion on the second voltage signal and outputs it. The voltage of the second voltage signal is the voltage across the current sensing element 10. The amplification factor can be determined by the R&D personnel's selection of the differential amplifier. For example, if the R&D personnel require a 10x amplification factor, a 10x differential amplifier will be selected. Thus, in actual applications, the back-end main control circuit 80 does not need to calculate the voltage across the current sensing element 10. The main control circuit 80 only needs to determine the current voltage drop across the current sensing element 10 based on the voltage value of the second voltage signal and a known preset amplification factor (which can be stored in the storage module or directly pre-stored in an external terminal).

[0072] After determining the voltage drop across the current sensing element 10, the main control circuit 80 can determine the temperature across the current sensing element 10 based on the first temperature detection signal and the second temperature detection signal, thereby determining the temperature difference across the two ends. The current thermoelectric potential difference is then determined based on a pre-stored temperature difference-thermoelectric potential difference mapping table obtained by R&D personnel based on multiple experiments. The actual voltage drop can then be obtained by subtracting the thermoelectric potential difference from the calculated voltage drop, thereby achieving a calibrated voltage drop. Finally, based on the calibrated voltage drop and the known resistance value of the current sensing element 10, the current value flowing through the current sensing element 10, i.e., the current value in the circuit to be measured, is calculated. The above configuration effectively improves the detection accuracy of the shunt.

[0073] In the technical solution of the present utility model, the shunt includes: a current sensing element 10, a first temperature detection module 40 and a second temperature detection module 50. The first temperature detection module 40 is arranged near the first end of the current sensing element 10, and is used to detect the temperature of the first end of the current sensing element 10 and output a corresponding first temperature detection signal; the second temperature detection module 50 is arranged near the second end of the current sensing element 10, and is used to detect the temperature of the second end of the current sensing element 10 and output a corresponding second temperature detection signal. In this way, when the shunt of the present application is actually used, the temperature at both ends of the shunt can be determined based on the first temperature detection signal and the second temperature detection signal, and the voltage drop on the actual current sensing element 10 can be corrected based on the temperature at both ends, so as to reduce the influence of the thermoelectric potential difference at both ends of the current sensing element 10 on the voltage drop, thereby effectively improving the detection accuracy of the shunt.

[0074] refer to Figure 3-Figure 5 In one embodiment of the present invention, the diverter further comprises:

[0075] a temperature control component 60 , the temperature control component 60 being electrically connected to the main control circuit 80 and being disposed near the first end of the current sensing element 10 or the second end of the current sensing element 10 ;

[0076] The main control circuit 80 is further configured to control the operation of the temperature control component 60 according to the first temperature detection signal and the second temperature detection signal.

[0077] In this embodiment, the temperature control component 60 can be implemented by using temperature control devices such as a heating film, a semiconductor refrigeration heating plate, etc.

[0078] Optionally, in one embodiment, referring to Figure 3The temperature control component 60 can be arranged near one end or the second end of the current sensing element 10. The main control circuit 80 can control the operation of the temperature control component 60 according to the first temperature detection signal and the second temperature detection signal, so that the temperature difference between the two ends of the current sensing element 10 is less than the preset temperature difference (preset by the R&D personnel after testing. When the temperature difference is less than the preset temperature difference, the thermoelectric potential difference will not have a significant impact on the detection accuracy of the shunt, so that the shunt can meet the required detection accuracy requirements). For example, refer to Figure 3 The temperature control component 60 is a semiconductor heating and cooling element. If the temperature of the first end of the current sensing element 10 is currently 70°C and the second end is 50°C, the main control circuit 80 can control the temperature control component 60 to heat up, raising the temperature of the second end to 70°C. This can reduce the thermoelectric potential difference between the two ends of the shunt, thereby effectively improving the accuracy of shunt detection.

[0079] Alternatively, in another embodiment, referring to Figure 4 The temperature control components 60 are multiple in number, each comprising at least one first temperature control component 61 and at least one second temperature control component 62. The first temperature control component 61 is positioned near the first end of the current sensing element 10, and the second temperature control component 62 is positioned near the second end of the current sensing element 10. In this embodiment, the main control circuit 80 can determine a target temperature based on the first temperature detection signal and the second temperature detection signal. The target temperature can be within or outside the range between the temperatures at both ends of the current sensing element 10. The first temperature control component 61 and the second temperature control component 62 are then controlled to operate simultaneously to adjust the temperatures at both ends to the target temperature. This configuration not only reduces the thermoelectric potential difference across the shunt, but also allows for more rapid and efficient simultaneous adjustment of the temperatures at both ends of the current sensing element 10, thereby ensuring that the temperatures at both ends of the current sensing element 10 are within the desired appropriate temperature range. This effectively ensures the reliability and stability of the current sensing element 10, and thus the reliability and stability of the shunt operation.

[0080] Optionally, in one embodiment, referring to Figure 3-Figure 5 The first end of the current sensing element 10 is connected to the first conductive element 20, the second end of the current sensing element 10 is connected to the second conductive element 30, and the temperature control assembly 60 is disposed on the first conductive element 20 or the second conductive element 30. This arrangement allows the temperature control assembly 60 to be closer to both ends of the current sensing element 10, thereby more effectively changing the temperature of the first end and / or the second end of the current sensing element 10.
