[0029] Optionally, the waterproof member 32 is made of EVA material, rubber material or PVC material. In the embodiment, the waterproof member 32 is made of EVA material. EVA is a kind of ethylene-vinyl acetate copolymer, which has good flexibility, rubber-like elasticity, good flexibility at low temperature, good transparency and surface gloss, good chemical stability, good anti-aging and ozone resistance, and no toxicity. The wireless communication device can also be used for communication between other devices at a long distance, such as instruments, inverters, environmental monitors and the like.

[0030] In the embodiment, the star flash module 34 of one communication structure is connected to the EMS device communication interface of the energy storage system 20 through a cable, and the star flash module 34 of the other communication structure is connected to the anti-reverse current electric meter 10 communication interface in the user power distribution system through a cable. The star flash module 34 and the EMS device and the anti-reverse current electric meter 10 adopt wired communication. The star flash technology is used to realize wireless communication between the anti-reverse current electric meter 10 and the EMS device. Star flash (NearLink) is a kind of wireless short-range communication technology, which can stably and quickly transmit data within a range of 50-100 meters and has strong anti-interference ability. Through the star flash module 34, a wireless transmission channel is established, and reliable transmission of electric meter 10 data at a short distance can be realized. When the distance is long, an intermediate cascade module can be added.

[0031] It is worth mentioning that the query instruction issued by the EMS device (energy storage system 20) is transmitted wirelessly to the star flash module 34 of the second communication component 30, and then to the anti-backflow electricity meter 10. After receiving the query instruction, the meter 10 transmits the monitored data through the star flash module 34 of the second communication component 30 to the star flash module 34 of the first communication component 30, and then uploads it to the EMS device, completing the data query. It can be seen that the data transmission between the EMS device of the energy storage system 20 and the anti-backflow electricity meter 10 is completed through the star flash module 34 of the communication component 30, avoiding the problem of long-distance cable laying and reducing construction cost, realizing fast and reliable wireless transmission of meter 10 data.

[0032] Please refer to Figures 3-4 Further, a communication hole 331 is formed on one side of the cover plate 33, and the communication hole 331 corresponds to the position of the antenna 341 of the star flash module 34. The waterproof member 32 extends a sealing part 321 away from the side of the accommodating cavity 35, and when the waterproof member 32 sealingly abuts against the annular end face 37 of the opening 36, the sealing part 321 extends to the communication hole 331, so that the periphery of the sealing part 321 sealingly abuts against the inner edge of the communication hole 331.

[0033] It is worth mentioning that in order to ensure smooth wireless communication and avoid the shielding effect of the antenna 341 by the shell 31 and the cover plate 33, the shell 31 is specially designed with a communication hole 331. The communication hole 331 corresponds to the antenna 341 accurately, which means that the communication hole 331 is arranged at the position of the cover plate 33 opposite to the antenna 341, so that the antenna 341 can transmit wireless signals through these holes. At the same time, the edge of the sealing part 321 closely fits the inner edge of the communication hole 331 to realize sealing and prevent liquid from penetrating into the interior. This design not only ensures the efficiency of wireless communication, but also ensures the waterproof performance of the device in various environments, improving the reliability and durability of the communication component 30.

[0034] In this embodiment, the cover plate 33, the annular end face 37 and the waterproof member 32 are all designed with fixing holes 391. When the cover plate 33 sealingly presses the waterproof member 32 against the annular end face 37 of the opening 36, the fixing holes 391 on the cover plate 33, the fixing holes 391 on the annular end face 37 and the fixing holes 391 on the waterproof member 32 will be accurately aligned. Then, by successively passing screws 39 through these three aligned fixing holes 391, it is ensured that the annular end face 37 of the shell 31 and the waterproof member 32 can be tightly fastened together, thereby maintaining their waterproof performance. This design ensures the close fit between components, enhances the stability and waterproof effect of the overall structure.

[0035] Further, the waterproof part 32 extends a positioning part 322 near one side of the accommodating cavity 35, and when the waterproof part 32 sealingly abuts against the annular end face 37 of the opening 36, the positioning part 322 extends into the accommodating space, so that the peripheral edge of the positioning part 322 sealingly abuts against the inner surface of the accommodating space.

[0036] It is worth noting that the design of the positioning part 322 plays an important role in improving the waterproof performance of the shell 31. The edge of the positioning part 322 is in close contact with the inner surface of the accommodating space, thereby enhancing the waterproof effect. In addition, the positioning part 322 also has the function of assembly positioning, simplifying the assembly process of the box body 38. When assembling the box body 38, the operator only needs to insert the positioning part 322 into the accommodating cavity 35 through the opening 36 of the shell 31, so that the fixing hole 391 of the waterproof part 32 is aligned with the fixing hole 391 on the annular end face 37. This step provides convenience for locking with the screw 39, ensuring the accuracy and efficiency of assembly. This design not only improves the waterproof performance of the product, but also optimizes the assembly process, making the product more easy to install and maintain.

[0037] Further, the shell 31 extends a fixing part 311 away from the opening 36, and the top of the fixing part 311 is provided with a fixing through hole 312, and the fixing through hole 312 penetrates through the fixing part 311 away from the shell 31. In specific applications, when installing the box body 38, the box body 38 can be fixed to an outdoor place, such as the wall of a building, by screwing the screw 39 through the fixing through hole 312 of the fixing part 311.
