If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0037] The applicant has found through research that currently, most companies install intelligent data acquisition terminals by adding additional intelligent data acquisition terminals to the built switch cabinets, which means that the original switch cabinets (switch cabinets to be installed) need to be modified. The specific process is as follows: open the original switch cabinet, and the installation worker unscrews the bolts of the voltage signal terminal block of the original switch cabinet, and uses a connecting wire to connect the original voltage signal terminal block with the voltage signal terminal block of the intelligent data acquisition terminal. However, the power supply needs to be disconnected when connecting the two, that is, the original switch cabinet is powered off before operation. Direct live operation is prone to safety accidents. However, it is difficult to coordinate power outages, especially power outages at the main gateway, which will cause the entire factory to stop production for a certain period of time, seriously affecting production efficiency, and in the process of the factory confirming that the power outage is allowed, the waiting time is long and the time cost is high.

[0038] Based on this, see Figure 1 , Figure 1 The diagram is a schematic diagram of the installation state of the live-installable intelligent data acquisition terminal 10 in one embodiment of the present application. The live-installable intelligent data acquisition terminal 10 provided in one embodiment of the present application includes an intelligent data acquisition body 100, a voltage signal collector 200 and a current signal collector 300.

[0039] The intelligent acquisition body 100 has a first voltage signal terminal row 110 and a first current signal terminal row 120, the voltage signal collector 200 is communicatively connected with the first voltage signal terminal row 110, and the voltage signal collector 200 has a magnetic steel connector 210, and the magnetic steel connector 210 is used to adsorb the second voltage signal terminal row 20 of the switch cabinet to be installed. The above-mentioned setting connects the voltage signal collector 200 with the second voltage signal terminal row 20 through the adsorption function of the magnetic steel connector 210 to realize the electrical connection between the voltage signal of the intelligent acquisition body 100 and the voltage signal of the switch cabinet to be installed, and there is no need to modify the line of the switch cabinet to be installed, thereby realizing the convenience of the installation process. During the specific installation, it is only necessary to find the corresponding second voltage signal terminal row 20 in the switch cabinet to be installed, and use the magnetic steel connector 210 to adsorb the voltage signal collector 200 on the conductor position of the second voltage signal terminal row 20, and use magnetic force to make a reliable connection, so as to obtain the voltage signal.

[0040] The current signal collector 300 is communicatively connected with the first current signal terminal block 120, and the current signal collector 300 includes a first current transformer 310, which is clamped at the secondary current outlet 30 of the second current transformer of the switch cabinet to be installed. The above arrangement connects the first current transformer 310 with the second current transformer in the form of clamping to realize the communication connection between the current signal of the intelligent collection body 100 and the current signal of the switch cabinet to be installed, avoiding the change of the original wiring in the switch cabinet to be installed.

[0041] The above-mentioned intelligent acquisition terminal 10 that can be installed with power, by setting the first voltage signal terminal block 110 of the intelligent acquisition main body 100 to be electrically connected with the voltage signal collector 200, the voltage signal collector 200 and the second voltage signal terminal block 20 are connected through the magnetic steel joint 210 of the voltage signal collector 200, so as to realize the communication connection between the voltage signal of the intelligent acquisition main body 100 and the voltage signal of the switch cabinet to be installed, without changing the original wiring in the switch cabinet; by setting the first current signal terminal block 120 of the intelligent acquisition main body 100 to be electrically connected with the current signal collector 300, the voltage signal collector 200 is the first current transformer 310 and is connected with the second current transformer, so as to realize the communication connection between the current signal of the intelligent acquisition main body 100 and the current signal of the switch cabinet to be installed, and also avoid changing the original wiring in the switch cabinet to be installed. That is, the voltage and current connections between the above-mentioned intelligent acquisition terminal and the switch cabinet to be installed do not need to be installed by power outage wiring, which improves work efficiency.

[0042] In order to more conveniently realize that the first current transformer 310 is clamped to the secondary current outlet 30 of the second current transformer of the switch cabinet to be installed, in a preferred embodiment, the first current transformer 310 is an open-type current transformer. It should be noted that the open-type current transformer is clamped to the second current transformer through its own opening, and the open-type current transformer is a common structure in the market, which will not be elaborated here.

[0043] In order to ensure that the scope of the accident does not expand as much as possible when the intelligent acquisition terminal fails, a preferred embodiment is that the intelligent acquisition terminal 10 that can be installed with power also includes a circuit protection device 400, which is arranged between the first voltage signal terminal block 110 and the voltage signal collector 200. The circuit protection device 400 is used to cut off the circuit between the first voltage signal terminal block 110 and the voltage signal collector 200 when the current flowing through itself is too high. When the circuit protection device 400 is working, when the current flowing through itself is too large, it cuts off the circuit between the first voltage signal terminal block 110 and the voltage signal collector 200 by fusing its own fuse, thereby ensuring that the scope of the accident does not expand when the intelligent acquisition terminal fails.

[0044] In specific settings, the circuit protection device 400 can be a fuse or a circuit breaker. It should be emphasized that the circuit protection device 400 is not limited to the above-mentioned electrical components, but can also be a circuit protection device 400 such as an air circuit breaker. Through the above settings, when the intelligent acquisition body 100 needs to be repaired or replaced, the circuit protection device 400 is pulled open to make the interface of the intelligent acquisition body 100 not energized, and the repair or replacement operation is safer, which plays a better role in protecting the staff.

[0045] At present, when additional intelligent data acquisition terminals are installed in various switch cabinets that have been built, the original switch cabinets are usually modified and the intelligent data acquisition terminals are installed in the original switch cabinets. However, there are many types of switch cabinets on site, and there is often a situation where there is insufficient space in the original switch cabinets and the intelligent data acquisition terminals cannot be installed. In this case, the original switch cabinets will be modified, which increases the cost on the one hand, and on the other hand, when the switch cabinets are relatively old, the modification may cause damage to the original lines.

[0046] Based on this, see Figure 2 and Figure 3 As shown, Figure 2 Schematic diagram of the opening structure of the installation box 500 in one embodiment of the present application. Figure 3 This is a front view of the installation box 500 in an embodiment of the present application. In some embodiments, in order to solve the problem that the switch cabinet to be installed has a small space and is difficult to install the intelligent acquisition terminal, a preferred embodiment is that the intelligent acquisition terminal 10 that can be installed with power also includes an installation box 500, which is arranged on the outside of the switch cabinet to be installed, and the installation box 500 is used to install the intelligent acquisition body 100.

[0047] In the specific setting, the installation box 500 can be set on the top, side wall, bottom or wall side of the switch cabinet to be installed. The intelligent acquisition main body 100 and the circuit protection device 400 are arranged at intervals in the installation box 500. The first current transformer 310 and the magnetic steel connector 210 of the voltage signal collector 200, which are connected to the intelligent acquisition main body 100 for communication, pass through the installation box 500 and are arranged in the switch cabinet to be installed. Through the above setting, the larger intelligent acquisition main body 100 and the circuit protection device 400 are integrated into a separate external installation box 500, and only the magnetic steel connector 210 and the small open-type current transformer are installed in the switch cabinet to be installed, so that the space occupied by the switch cabinet to be installed is small, which solves the problem that the space of the switch cabinet to be installed is small and it is difficult to install the intelligent acquisition terminal, and improves the applicability of the intelligent acquisition terminal. In addition, the external installation box 500 can be easily installed on the outside or wall of the switch cabinet to be installed by screws, bolts or adhesive bonding, and the entire installation process is simple and efficient.

[0048] See also Figure 4 and Figure 5 As shown, Figure 4FIG. 5 is a bottom view of an installation box 500 in an embodiment of the present application. Figure 5 It is a top view of the installation box 500 in one embodiment of the present application. In some embodiments, in order to facilitate the voltage signal collector 200 and the current signal collector 300 to pass through the installation box 500, specifically, the installation box 500 has a first inner cavity 511 for installing the intelligent collection body 100, and the voltage signal collector 200 and the current signal collector 300 are both passed through the cavity wall of the first inner cavity 511 and are located outside the installation box 500. In the specific setting, the installation box 500 is provided with a first through hole 512 connected to the first inner cavity 511, and the number of the first through holes 512 is multiple. In the present application, the number of the first through holes 512 is preferably two and opened at the bottom of the installation box 500. The voltage signal collector 200 and the current signal collector 300 are respectively passed through the two first through holes 512 and are located outside the installation box 500, so as to facilitate the subsequent installation in the switch cabinet to be installed.

[0049] In order to enhance the signal of the intelligent acquisition body 100, an antenna is provided on the intelligent acquisition body 100, and the side of the antenna facing away from the intelligent acquisition body 100 is penetrated through the installation box 500 and is located outside the installation box 500. In order to facilitate the antenna to pass through the installation box 500, a second through hole 513 connected to the first inner cavity 511 is opened on the installation box 500, and the second through hole 513 is preferably opened at the top of the installation box 500, and the second through hole 513 is used for the antenna to pass through.

[0050] See again Figure 3 In order to design the installation box 500 more conveniently, more specifically, the installation box 500 includes a box body 510 and a cover plate 520. The box body 510 is a cavity structure with one end open. The box body 510 has a first inner cavity 511. The open end of the box body 510 is provided with a cover plate 520 rotatably covering the box body 510. In the specific setting, a door lock 530 is also provided on the cover plate 520, and the cover plate 520 is opened and closed relative to the box body 510 through the door lock 530. Through the above setting, when the intelligent acquisition main body 100 needs to be repaired or replaced, the cover plate 520 is opened, the circuit protection device 400 is pulled open, and then the intelligent acquisition main body 100 is repaired or replaced, without touching the switch cabinet to be processed, and the original equipment in the switch cabinet to be processed will not be damaged.

[0051] See again Figure 4 In order to enhance the heat dissipation of the intelligent data collection terminal 10 that can be installed with power, a plurality of heat dissipation holes 514 arranged at intervals are further provided on the box body 510, and the heat dissipation holes 514 are used to connect the first inner cavity 511 with the outside air. In the specific setting, the heat dissipation holes 514 can be arranged in a matrix of multiple rows and columns, and can be 2 rows and 8 columns, 2 rows and 15 columns, 3 rows and 5 columns, and other matrix forms.

[0052] In order to more conveniently observe the situation of the intelligent data collection body 100 and the circuit protection device 400 in the installation box 500, the cover plate 520 is further a transparent plate. In specific settings, the entire cover plate 520 may be a transparent plate, or a partial area of ​​the cover plate 520 may be a transparent plate. The specific transparent plate may be made of glass.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
