Description
Technical Field
[0001] The utility model belongs to the technical field of a single host reading data of multiple sets of coils, in particular to a coil set capable of reading data of multiple sets of coils. Background Art
[0002] Generally speaking, electrical appliances require the correct voltage and current to generate sufficient energy for smooth operation. However, in practice, voltage and current can easily fluctuate due to various external factors and interference. Current technology can only provide relatively stable voltage and current for equipment, but cannot yet achieve absolutely stable voltage and current. Therefore, real-time monitoring of the voltage and current of important electrical equipment during operation is extremely important. This allows for the immediate detection and resolution of any abnormal voltage or current.
[0003] Currently, there are many methods available on the market for monitoring device current, such as current transformers and Rogowski coils. Among them, the use of Rogowski coils is the most mainstream method in the industry today. In order for monitoring equipment to obtain the current value detected by the Rogowski coil, it is necessary to use a dedicated current measuring host. However, currently available current measuring hosts are only compatible with one set of Rogowski coils. If there are multiple nodes that need to detect current, multiple current measuring hosts are required, and each current measuring host requires a certain amount of space.
[0004] In view of the above problems, it can be seen that the existing existing combination of multiple Loess coils and an electrical measuring host requires each Loess coil to be equipped with an electrical measuring host, which takes up too much space. It is necessary to improve this problem.
[0005] Therefore, it is urgent to design a coil set that can read data from multiple coils to solve the above-mentioned problems. Utility Model Content
[0006] The present invention aims to provide a coil assembly capable of reading data from multiple coil groups. The assembly comprises a microprocessor control unit disposed within a host computer. When multiple Ludwigshafen coils are mounted on the host computer, the microprocessor control unit reads and returns current data from the multiple Ludwigshafen coils at once based on internal programming and computational logic. This achieves the advantage of matching multiple Ludwigshafen coils to a single host computer, thereby resolving the problems mentioned in the prior art.
[0007] To achieve the above objectives, the specific technical solutions of the coil set capable of reading data of multiple coils of the present invention are as follows:
[0008] Coil sets that can read multiple sets of coil data, including;
[0009] A plurality of Ludwig coils, each comprising a coil input unit, a multi-stage switching unit, an amplifying circuit unit, an overload protection unit, and an analog-to-digital conversion unit electrically connected in sequence, wherein the multi-stage switching unit has a low-range measurement mode and a high-range measurement mode;
[0010] A host comprising a microprocessor control computing unit, a wireless transmission unit, a DC-DC voltage conversion unit, and a wired USB power transmission unit, wherein the microprocessor control computing unit is electrically connected to the wireless transmission unit and the wired USB power transmission unit, and the DC-DC voltage conversion unit is electrically connected to the wired USB power transmission unit;
[0011] When the plurality of Loessell coils are respectively arranged on the host, the plurality of Loessell coils are respectively electrically connected to the microprocessor control calculation unit of the host through their own multi-stage switching units and analog-to-digital conversion units.
[0012] Furthermore, the microprocessor control calculation unit is electrically connected to an Ethernet transmission unit.
[0013] Furthermore, the multi-stage switching unit defaults to the high-speed measurement mode.
[0014] Furthermore, when the current value detected by the multiple Ludwigshafen coils is less than the default value of the file position switch set inside the microprocessor control calculation unit, the microprocessor control calculation unit controls the multi-stage switching unit to switch to the low-speed measurement; when the current value detected by the multiple Ludwigshafen coils is greater than the default value of the file position switch set inside the microprocessor control calculation unit, the microprocessor control calculation unit controls the multi-stage switching unit to switch to the high-speed measurement.

[0055] The microprocessor control calculation unit 21 is electrically connected to an Ethernet transmission unit 25 .
[0056] The multi-stage switching unit 12 is in the high-speed measurement mode by default.
[0057] When the current value detected by the multiple Ludwigshafen coils 1 is less than the default value of the file position switch set in the microprocessor control calculation unit 21, the microprocessor control calculation unit 21 controls the multi-stage switching unit 12 to switch to the low-speed measurement. When the current value detected by the multiple Ludwigshafen coils 1 is greater than the default value of the file position switch set in the microprocessor control calculation unit 21, the microprocessor control calculation unit 21 controls the multi-stage switching unit 12 to switch to the high-speed measurement.
[0058] Continuing with the above content, the implementation method of the present invention is further described in detail with reference to Figures 1 to 12. The method includes the following steps: a plurality of Loris coils 1 are provided, each of which includes a coil input unit 11, a multi-stage switching unit 12, an amplifying circuit unit 13, an overload protection unit 14, and an analog-to-digital conversion unit 15 electrically connected in sequence; a host 2 is provided, the host 2 must have a microprocessor control calculation unit 21, and the microprocessor control calculation unit 21 has multiple sets of input points; the plurality of Loris coils 1 are then connected to the host 2. The plurality of Ludwig coils 1 are arranged on the host 2 so that the analog-to-digital conversion unit 15 built into each of the plurality of Ludwig coils 1 is electrically connected to each input point of the microprocessor control calculation unit 21; the plurality of Ludwig coils 1 are arranged on the wire to be tested; each Ludwig coil 1 is connected to detect the current in the corresponding wire, and the current passes through the coil input unit 11, the multi-stage switching unit 12, the amplifying circuit unit 13, the overload protection unit 14, the analog-to-digital conversion unit 15, and the microprocessor control calculation unit 21 in sequence, so that the microprocessor control calculation unit 21 The calculation unit 21 is capable of reading the current data detected by each Ludwigshafen coil 1. The multi-stage level switching unit 12 includes a low-range measurement mode and a high-range measurement mode, with the high-range measurement mode being the default setting. The microprocessor-controlled calculation unit 21 switches the level of the multi-stage switching unit 12 based on the following conditions: when the current values detected by the plurality of Ludwigshafen coils 1 are less than a default level switching value set within the microprocessor-controlled calculation unit 21, the multi-stage switching unit 12 switches to the low-range measurement mode; when the current values detected by the plurality of Ludwigshafen coils 1 are greater than the default level switching value set within the microprocessor-controlled calculation unit 21, the multi-stage switching unit 12 switches to the high-range measurement mode. The microprocessor-controlled calculation unit 21 then reads the current data read by the plurality of Ludwigshafen coils 1 at a time according to its internal programming and calculation logic, and transmits the data to the corresponding device. The current data read by the host 2 can be transmitted via an Ethernet transmission unit 25, a wireless transmission unit 22, or a wired USB power transmission unit 24 within the host 2.
