Referring to fig. 1, fig. 1 is a functional block diagram of a first embodiment of a nickel plate wire harness detection circuit according to an embodiment of the present utility model, and based on fig. 1, a first embodiment of a nickel plate wire harness detection circuit according to the present utility model is proposed.
As shown in fig. 1, in this embodiment, the nickel plate harness detection circuit includes: a plurality of control modules 20, an analog-to-digital conversion module 10 corresponding to each control module, and a multi-channel display module 30 composed of a preset number of display units;
each analog-to-digital conversion module 10 is respectively connected with the wire harness 1 to be detected and the corresponding control module 20, and each control module is connected with the multi-path display module 30;
the analog-to-digital conversion module 10 is configured to convert an analog voltage signal input by the wire harness 1 to be detected into a digital voltage signal, and transmit the digital voltage signal to the corresponding control module 20;
the control module 20 is configured to generate a detection voltage signal according to the voltage value of the digital voltage signal and a preset voltage value, which are received and transmitted by the corresponding analog-to-digital conversion module 10, and transmit the detection voltage signal to a corresponding display unit in the multi-channel display module 30.
It should be noted that, because the number of nickel sheet wire harnesses in the battery pack is too large, the existing nickel sheet wire harness detection method is that on-off test is performed through a universal meter or on-machine detection is performed, the detection efficiency is too low, and the condition of missing detection or false detection is easy to occur, so that the detection efficiency is low, and in this embodiment, a plurality of control modules 20 can be adopted to detect whether the states of a plurality of wire harnesses are normal or not in cooperation with a plurality of analog-digital conversion modules 10. And meanwhile, the speed of wire harness detection can be increased by using a plurality of control modules to carry out wire harness scanning, namely, multipath analog-to-digital conversion is carried out at the same time, and data acquisition of all wire harnesses in one battery pack can be realized in a short time, so that detection results of all nickel plate wire harnesses to be detected corresponding to the battery pack can be obtained in a short time. It is to be understood that, in the present embodiment, the number of the control modules 20 of the nickel sheet wire harness detection circuit is at least two, and the specific number can be specifically set according to the actual situation, which is not limited in the present embodiment.
It should be understood that the wire harness 1 to be detected is a wire harness connected between a power supply and the analog-digital conversion module 10 and is being subjected to on-off test. If the wire harness 1 to be detected is normal, the voltage signal output by the power supply can be input into the analog-to-digital conversion module 10 through the wire harness 1 to be detected and then is transmitted to the control module 20; otherwise no voltage signal is sent to the control module 20.
It can be understood that, in order to further increase the detection speed, the embodiment may divide different preset voltage values for each nickel sheet, so as to determine that a nickel sheet wire harness is normal when it is detected that the voltage value of a digital voltage signal corresponding to the nickel sheet wire harness matches with the corresponding preset voltage value; when the voltage value of the digital voltage signal corresponding to a certain nickel sheet wire harness is not matched with the corresponding preset voltage value, the abnormality of the nickel sheet wire harness is judged, and the control module 20 generates a corresponding detection voltage value signal according to the matching condition and transmits the detection voltage value signal to the multi-path display module 30.
Further, the detecting the voltage signal in this embodiment includes: a turn-on signal;
the control module 20 is further configured to generate the on signal and send the on signal to a corresponding display unit in the multi-path display module 30 when detecting that the voltage value of the digital voltage signal sent by the corresponding analog-to-digital conversion module 10 is equal to the preset voltage value.
The detection voltage signal further includes: cut-off signal;
the control module 20, the control module 20 is configured to generate the cut-off signal and send the cut-off signal to a corresponding display unit in the multi-path display module 30 when detecting that the voltage value of the digital voltage signal sent by the corresponding analog-to-digital conversion module 10 is not equal to the preset voltage value.
It should be noted that, in this embodiment, the voltage collection range of the analog-to-digital conversion module 10 may be divided into a plurality of levels, where each level corresponds to a different analog signal range and an analog-to-digital conversion value, and the analog-to-digital conversion value is the preset voltage value. Therefore, if the control module 20 detects that the voltage value of the digital voltage signal currently transmitted by the analog-to-digital conversion module 10 is inconsistent with the corresponding preset voltage value, it can determine that the nickel sheet wire harness corresponding to the currently input digital voltage signal is abnormal, and the corresponding cut-off signal can be transmitted to the multiple display modules 30 according to the embodiment, so that the corresponding display units in the multiple display modules 30 are not displayed; if it is detected that the voltage value of the digital voltage signal currently transmitted by the analog-to-digital conversion module 10 is consistent with the corresponding preset voltage value, it can be determined that the nickel sheet wire harness corresponding to the currently input digital voltage signal is normal, and the corresponding conducting signal can be transmitted to the multi-path display module 30, so that the corresponding display unit in the multi-path display module 30 can display, and further, a detector can intuitively and rapidly determine whether the state of each wire harness 1 to be detected is normal according to the display state of the display unit.
Further, in this embodiment, each of the display units includes: an LED lamp;
the LED lamp is connected with a data transmission pin of a corresponding RISC-V chip.
It should be understood that the preset number of display units in the multi-path display module 30 and the wire harness 1 to be detected have a corresponding relationship, and can be used for intuitively and immediately displaying whether the state of each wire harness is normal, while in the embodiment, each display unit may be an LED lamp, that is, each LED lamp has a one-to-one corresponding relationship with each wire harness 1 to be detected. If no abnormality exists in the current wire harness detection, the corresponding LED lamp is lighted; if the current wire harness detects abnormality, the corresponding LED lamp is turned off.
In a specific implementation, the voltage acquisition range 0-3.3V may be divided into corresponding values 0-4095, each wire harness 1 to be detected is placed at a corresponding wire harness detection position, different positions may correspond to different voltage levels, that is, the wire harnesses placed at different positions may correspond to different target analog signal ranges and preset voltage values, if the digital voltage signal corresponding to the wire harness input control module 20 placed at a certain position is inconsistent with the preset voltage value corresponding to the position, that is, the wire harness at the position is abnormal, the control module 20 may output a cut-off signal to the LED lamp corresponding to the position, so that the corresponding LED lamp is not displayed; if the digital voltage signal corresponding to the wire harness input control module 20 placed at a certain position is inconsistent with the preset voltage value corresponding to the position, that is, the wire harness at the position is abnormal, the control module 20 can output a cut-off signal to the LED lamp corresponding to the position, so that the corresponding LED lamp is not displayed. Therefore, the inspector can intuitively and rapidly know whether the state of each wire harness is normal or not. Therefore, the nickel plate wire harness detection circuit improves the detection speed and the accuracy of wire harness detection, and then the BMS faults caused by the wire harness in the battery are reduced. And the yield of the battery is improved.
The embodiment provides a nickel piece pencil detection circuitry, this nickel piece pencil detection circuitry includes: the system comprises a plurality of control modules, an analog-to-digital conversion module corresponding to each control module and a plurality of display modules consisting of a preset number of display units; each analog-to-digital conversion module is respectively connected with the wire harness to be detected and the corresponding control module, and each control module is connected with the multi-path display module; the analog-to-digital conversion module is used for converting an analog voltage signal input by the wire harness to be detected into a digital voltage signal and transmitting the digital voltage signal to the corresponding control module; when detecting that the voltage value of the digital voltage signal transmitted by the corresponding analog-to-digital conversion module is equal to the preset voltage value, generating a conduction signal and transmitting the conduction signal to a corresponding display unit in the multi-path display module; and the control module is also used for generating a cut-off signal to be transmitted to a corresponding display unit in the multi-path display module when the voltage value of the digital voltage signal transmitted by the corresponding analog-to-digital conversion module is detected to be unequal to the preset voltage value. Therefore, the digital voltage signals corresponding to the wire harnesses to be detected can be quickly obtained and detected through the plurality of control modules and the analog-to-digital conversion modules corresponding to the control modules, and the detection voltage signals are transmitted to the corresponding display units according to the detection results. Namely, according to the embodiment, a detector can intuitively and rapidly acquire whether the state of the wire harness corresponding to each display unit is normal or not according to each display unit in the multi-path display module, and the wire harnesses to be detected at each detection position correspond to each display unit one by one, so that the conditions of missed detection and false detection are avoided, and the detection speed and the detection accuracy of the wire harness detection are improved.
Referring to fig. 2, fig. 2 is a functional block diagram of a second embodiment of a nickel plate harness detection circuit according to an embodiment of the present utility model.
As shown in fig. 2, in the present embodiment, the analog-to-digital conversion module 10 includes: analog-to-digital converters and analog quantity expansion modules corresponding to the analog-to-digital converters;
the analog-to-digital converter is respectively connected with a corresponding control module 20 and a corresponding number of analog quantity expansion modules, and the analog quantity expansion modules are respectively connected with the wire harness 1 to be detected and the corresponding control module 20;
the analog quantity expansion module is used for conveying the analog voltage signal input by the wire harness 1 to be detected to the corresponding analog-to-digital converter;
the analog-to-digital converter is configured to convert an analog voltage signal delivered by a corresponding analog quantity expansion module into the digital voltage signal, and deliver the digital voltage signal to the corresponding control module 20.
It should be understood that the number of analog-to-digital conversion channels corresponding to each control module is limited, and the number of nickel sheet wire bundles corresponding to each battery management system is too high, so that the number of analog-to-digital conversion channels for data acquisition by only using a plurality of control modules 20 cannot meet the requirement, or the total number of control modules 20 needs to be increased, so that the cost is too high. Therefore, in this embodiment, while the plurality of control modules 20 are used for data acquisition, each control module is correspondingly connected to the analog quantity expansion module to increase the channels of analog-to-digital conversion sampling, so as to detect more nickel wire bundles, so as shown in fig. 2, each analog-to-digital conversion module may include an analog-to-digital converter correspondingly connected to the control module 20 and an analog quantity expansion module corresponding to each analog-to-digital converter, where each control module has a one-to-one correspondence with each analog-to-digital converter and each analog quantity expansion module.
Further, in the present embodiment, the control module 20 includes: RISC-V chip;
the first to third data processing pins of the RISC-V chip are connected with corresponding analog-to-digital converters;
the first to third data control pins of the RISC-V chip are connected with the corresponding analog quantity expansion modules;
the data transmission pins of the RISC-V chip are connected with the corresponding display units.
In the detection, the control module 20 does not perform the state detection (or voltage detection) on the plurality of wire harnesses at the same time, but performs the data acquisition and detection in a scanning manner in sequence. Meanwhile, in order to further detect the speed, the embodiment can adopt a RISC-V instruction set architecture with low power consumption, low cost, small area and high speed for data acquisition and detection. For easy understanding, taking fig. 3 as an example for illustration, fig. 3 is a schematic control diagram of a single control module 20 in a second embodiment of the nickel plate harness detection circuit according to the embodiment of the present utility model, as shown in fig. 3, each RISC-V chip may be connected to an analog-to-digital converter and an analog-to-digital expansion module through first to third data processing pins. Each analog-to-digital converter may include three analog-to-digital conversion channels (i.e., analog-to-digital conversion channel 1, analog-to-digital conversion channel 2, and analog-to-digital conversion channel 3 in fig. 3), and correspondingly, the analog-to-digital expansion module may include three analog-to-digital expansion units (i.e., analog-to-digital expansion unit 1, analog-to-digital expansion unit 2, and analog-to-digital expansion unit in fig. 3). It can be understood that in this embodiment, each RISC-V chip may be correspondingly connected to three analog-to-digital conversion channels, and each analog-to-digital expansion unit corresponding to each analog-to-digital conversion channel may include 8 channels (or 6 channels), so each RISC-V chip in this embodiment may correspondingly receive and determine 24 analog-to-digital conversion signals. The receiving order of the data conversion signals of each path can be determined through the first to third data control pins between the analog quantity expansion module and the RISC-V chip. In addition, each RISC-V chip can output a turn-on signal or a turn-off signal to each display unit, that is, each LED lamp, according to the data transmission pins, so that a user can judge the state of the current wire harness by observing the state of each LED, as shown in fig. 3, each LED has a one-to-one correspondence with each wire harness, for example, if the wire harness 1 is normal, the LED1 is on; if the wire harness n is abnormal, LEDn is deactivated.
It is to be understood that the total number of the harnesses of the conventional battery management system is generally 48, so the total number of the control modules 20 in this embodiment may be two, but in order to be compatible with a plurality of battery management systems or a battery management system adapted to other total number of the harnesses, the total number of the control modules 20 in this embodiment may be three or more, so the specific number of the control modules 20 in this embodiment is not limited thereto.
In the specific implementation, a detector only needs to place the assembled wire harness on the detection position, and after one full scan, the state of the corresponding wire harness can be displayed through each LED, namely, a user can judge the state of the current wire harness by observing the state of each LED, so that the detection speed of the wire harness is greatly improved. Meanwhile, in order to increase the detection speed, the control module 20 can be always in an analog-digital conversion signal acquisition state, so that the harness detection is ensured to update the display information at the same time when the harness 1 to be detected is continuously replaced, and the purpose of pipeline detection is achieved.
The embodiment discloses an analog-to-digital conversion module comprising: analog-to-digital converters and analog quantity expansion modules corresponding to the analog-to-digital converters; the analog-to-digital converter is respectively connected with a corresponding control module and a corresponding number of analog quantity expansion modules, and the analog quantity expansion modules are respectively connected with the wire harness to be detected and the corresponding control modules; the analog quantity expansion module is used for transmitting an analog voltage signal input by the wire harness to be detected to the corresponding analog-to-digital converter; and the analog-to-digital converter is used for converting the analog voltage signal transmitted by the corresponding analog quantity expansion module into a digital voltage signal and transmitting the digital voltage signal to the corresponding control module. The control module comprises: RISC-V chip; the first to third data processing pins of the RISC-V chip are connected with the corresponding analog-to-digital converters; the first to third data control pins of the RISC-V chip are connected with the corresponding analog quantity expansion modules; the data transmission pins of the RISC-V chip are connected with the corresponding display units.
