[0002] The reliability of hot-swap modules in distribution terminals is an important indicator for the development of distribution network automation and intelligence. However, in engineering applications, since most distribution terminals work on the line side, they often need to draw power from the primary line, and the primary line voltage level is relatively high. If the hot-swap technology of the distribution terminal itself is not perfect, the potential impact of the primary line voltage disturbance will also directly affect the reliable application of the terminal hot-swap technology.

[0046] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] For easier understanding, see Figure 1 , a distribution terminal hot-swap module monitoring device based on electromagnetic monitoring provided by the present invention is applied to a hot-swap module, the hot-swap module includes multiple functional modules and a primary circuit, including: a magnetic sensor module 10, an electromagnetic monitoring module 20, a main control module 30 and a power-off execution module 40;

[0048] Among them, the functional modules include power supply, signal acquisition module, MCU module, etc., and the primary circuit includes the voltage input circuit of the hot-swap module and the connection between each functional module.

[0049] The magnetic sensing module 10 is used to collect magnetic signals of each functional module in a preset frequency domain, and is also used to send the magnetic signals to the electromagnetic monitoring module 20;

[0050] It is understandable that each functional module will generate a magnetic signal within a predetermined frequency domain when working, and the magnetic signal of the corresponding functional module can be acquired through the magnetic sensor module 10.

[0051] The electromagnetic monitoring module 20 is used to collect the first electrical signal of the primary line, and is also used to convert the magnetic signal sent by the electromagnetic monitoring module 20 into a second electrical signal, and is also used to send the first electrical signal and the second electrical signal to the main control module 30 through multiple channels respectively;

[0052] Among them, the modules corresponding to the first electrical signal and the second electrical signal obtained by the electromagnetic monitoring module 20 are not the same. Therefore, the first electrical signal and the second electrical signal are transmitted separately through multiple channels, so that the first electrical signal and the second electrical signal are classified and do not interfere with each other.

[0053] The main control module 30 is used to determine whether the first electrical signal and the second electrical signal are abnormal, and is also used to send the abnormality determination result to the power-off execution module 40;

[0054] The power-off execution module 40 is used to power off the line between the corresponding primary line and the functional module connected thereto if the first electrical signal is determined to be abnormal; and is also used to power off the corresponding functional module if the second electrical signal is determined to be abnormal.

[0055] It should be noted that the present invention provides a distribution terminal hot-swappable module monitoring device based on electromagnetic monitoring, which collects magnetic signals of each functional module in a preset frequency domain through a magnetic sensor module 10, and then collects the first electrical signal of the primary line through an electromagnetic monitoring module 20, and converts the magnetic signal into a second electrical signal, and determines whether the first electrical signal and the second electrical signal are abnormal through a main control module 30. If the first electrical signal is determined to be abnormal, the line between the corresponding primary line and the functional module connected to it is powered off, and if the second electrical signal is determined to be abnormal, the corresponding functional module is powered off. In this way, the abnormal module can be quickly powered off and isolated, and at the same time, the electrical signal is collected through different collection methods, so as to realize the rapid positioning of the abnormal module.

[0056] In a specific embodiment, Figure 2 As shown, the magnetic sensor module 10 includes a base plate 11, a spiral coil 12, a contact module, a first frequency domain module, a second frequency domain module and a third frequency domain module;

[0057] A spiral coil 12 is disposed on the bottom plate 11. The spiral coil 12 is disposed above the functional module. The spiral coil 12 forms a plurality of spiral spacing regions along the length direction. The spiral spacing regions are provided with magnetic blocks 14.

[0058] The bottom plate 11 is made of a non-magnetic aluminum plate, the pitch of the spiral coil 12 is 15-20 mm, and the magnetic block 14 is made of No. 10 steel with good magnetic conductivity.

[0059] There are three contact modules, each of which includes two contacts 13. The two contacts 13 are staggered on both sides of the spiral coil 12, and the coil lengths between the two contacts 13 corresponding to each contact module are different.

[0060] The three contact modules are electrically connected to the first frequency domain module, the second frequency domain module and the third frequency domain module respectively;

[0061] The first frequency domain module is used to filter the magnetic signals collected by the corresponding contact module according to the preset first magnetic frequency domain, so as to only allow the magnetic signals within the preset first magnetic frequency domain to pass;

[0062] The second frequency domain module is used to filter the magnetic signals collected by the corresponding contact module according to the preset second magnetic frequency domain, so as to only allow the magnetic signals within the preset second magnetic frequency domain to pass;

[0063] The third frequency domain module is used to filter the magnetic signals collected by the corresponding contact module according to the preset third magnetic frequency domain, so as to only allow the magnetic signals within the preset third magnetic frequency domain to pass.

[0064] Specifically, the working process of the magnetic sensing module is:

[0065] The magnetic sensing module is placed above the functional module. The hot-swappable functional module generates a magnetic field in the space when working. After the spiral coil 12 senses the magnetic signal, it sends the magnetic signal to the frequency domain module through the contacts at both ends. The frequency domain module filters the corresponding magnetic signal, so that only the magnetic signal within the preset magnetic frequency domain is allowed to pass, thereby obtaining the magnetic signal of the specified frequency domain.

[0066] In a specific embodiment, the three frequency domain modules are divided into a low-frequency magnetic signal, a medium-frequency magnetic signal, and a high-frequency magnetic signal, wherein the first frequency domain module, the second frequency domain module, and the third frequency domain module are all provided with a debugging resonant circuit, and the debugging resonant circuit is used to adjust the peak range of the corresponding magnetic frequency domain to make relevant parameters adjustable, including the peak-to-peak value of the output voltage.

[0067] Taking frequency domain module i as an example, under the normal working state of the hot-swappable module, according to the characteristics of magnetic signals generated by low / medium / high frequencies, low / medium / high frequency debugging circuits are used to debug low / medium / high frequency output electrical signals respectively. During the debugging process, the output voltage peak-to-peak value E is taken as the observation object, and the maximum output voltage peak-to-peak value E is obtained as the debugging target, and the position of the corresponding contact is adjusted to obtain the corresponding low / medium / high frequency output signal. After obtaining the maximum output voltage peak-to-peak value E, the position of the corresponding contact is recorded to complete this step of the debugging process; after completing the debugging of the contact position, the values ​​of the series-parallel resonant circuits are debugged in turn to obtain the maximum output voltage peak-to-peak value E as the debugging target. After completing the debugging, the debugging results are recorded; during the debugging process, the low-frequency signal band is defined as <300Hz, the medium-frequency signal band is defined as 300Hz-20kHz; and the high-frequency signal band is defined as >20kHz.

[0068] In a specific embodiment, the main control module 30 includes a signal processing module, a first signal analysis module, a second signal analysis module and an output module;

[0069] The signal processing module is used to filter and amplify the first electrical signal and the second electrical signal, and is also used to send the filtered and amplified first electrical signal and the second electrical signal to the first signal analysis module and the second signal analysis module respectively;

[0070] The first signal analysis module is used to determine whether the first electrical signal has overvoltage or undervoltage, and if it is determined that the first electrical signal has overvoltage or undervoltage, a first power-off signal is generated and sent to the output module;

[0071] The first signal analysis module is used to determine whether the second electrical signal exceeds a preset voltage threshold, and if it is determined that the second electrical signal exceeds the preset voltage threshold, a second power-off signal is generated and sent to the output module;

[0072] The output module is used to send the first power-off signal and the second power-off signal to the power-off execution module 40 .

[0073] It should be noted that this embodiment realizes online status monitoring and abnormal status identification of the hot-swappable module of the power distribution terminal by monitoring the electrical signals of the primary circuit and the functional module, wherein whether to perform a power-off operation is determined by judging whether the first electrical signal is overvoltage (such as the actual voltage>1.2 times the rated voltage) or undervoltage (such as the actual voltage<0.8 times the rated voltage). If the voltage of the primary circuit is abnormal, a power-off operation is performed to prevent each hot-swappable module from being affected by the impact of the abnormal primary circuit;

[0074] Secondly, whether the power supply of the hot-swap module is abnormal is determined by judging whether the second electrical signal is abnormal (for example, if the actual voltage is 0.9-1.1 times the rated voltage, it is recorded as normal).

[0075] In a specific embodiment, the system further includes an early warning module for receiving a power-off signal generated when the power-off execution module 40 performs a power-off operation, thereby issuing an early warning signal.
