[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] An intelligent monitoring and control device for a ring main unit, such as Figures 1-5 As shown, the device includes a first outer casing 1 and a second outer casing 2. A main board 17 is fixedly installed on the inner wall of the first outer casing 1. A communication module 4, a temperature sensor 5, and a humidity sensor 6 are arranged inside the first outer casing 1 and the second outer casing 2, located on one side of the main board 17. Connection mechanisms are provided on both outer sides of the communication module 4, the temperature sensor 5, and the humidity sensor 6. A control module 14 is fixedly installed on the back of the main board 17. The connection mechanism includes a T-shaped plug 8 and a screw 9. The T-shaped plug 8 is fixedly connected to the outer wall of the communication module 4, and the screw 9 is fixedly connected to the outer wall of the second outer casing 2.
[0027] The communication module 4, temperature sensor 5, and humidity sensor 6 are all electrically connected to the main board 17 via connectors. The control module 14 is fixed on the back of the main board 17, which is used to receive sensor signals, process data, and upload them to the monitoring center or local display unit through the communication module 4 for intelligent monitoring and control of the ring network cabinet. The temperature sensor 5 is an ATE400 model, and the humidity sensor 6 is a PT100 model. The communication module 4 can be a wired or wireless communication module to realize data transmission with the remote monitoring center or local display device.
[0028] The screw 9 is threaded with a stop 10, which cooperates with the T-shaped plug 8. The connecting mechanism also includes a T-shaped groove 7, which is opened on the inner side wall of the outer casing 1. The T-shaped groove 7 fits with the T-shaped plug 8. When installing the communication module 4, the T-shaped plug 8 is inserted along the T-shaped groove 7 to achieve the initial positioning of the communication module 4.
[0029] Specifically, the inner wall of the stop block 10 is provided with threads that fit with the outer wall of the screw 9. Through the engagement of the threads, when the stop block 10 rotates to be in close contact with the T-shaped plug 8 and is in a lateral position, it can lock with the screw 9 and limit the T-shaped plug 8. By rotating the stop block 10, it moves along the axial direction of the screw 9 and presses against the T-shaped plug 8, thus achieving a stable lock on the communication module 4. This allows the T-shaped plug 8 to be fixed in the T-shaped groove 7, making it easy to install the communication module 4 in the outer casing 2. Similarly, by rotating the stop block 10 in the opposite direction and placing it in a vertical position, the pressing and blocking of the T-shaped plug 8 can be released, allowing the T-shaped plug 8 to be removed from the T-shaped groove 7, making it easy to remove the communication module 4. Similarly, the temperature sensor 5 and humidity sensor 6 can be easily installed and removed, making the intelligent measurement and control device easy to quickly install and remove various sensors and modules, enhancing maintenance convenience.
[0030] The bottom surface of the outer shell 2 is fixedly connected to the insert plate 15, and the upper surface of the outer shell 1 is provided with a slot 16. The slot 16 fits into the insert plate 15. When the insert plate 15 installed on the bottom surface of the outer shell 1 is inserted into the slot 16, it can achieve initial connection and alignment with the outer shell 2.
[0031] The outer wall of the second outer shell 2 is rotatably connected to a movable plate 11 via a shaft. The outer wall of the first outer shell 1 is fixedly connected to an L-shaped fixing plate 12. A fixing screw 13 is inserted into the outer wall of the L-shaped fixing plate 12. A screw groove is opened on the outer wall of the movable plate 11, and the screw groove and the fixing screw 13 cooperate with each other. By rotating the movable plate 11, it is locked inside the L-shaped fixing plate 12. The fixing screw 13 passes through the movable plate 11 and rotates into the screw groove, so that it can be fastened to the L-shaped fixing plate 12. This realizes the convenient and reliable installation of the first outer shell 1 and the second outer shell 2. Similarly, the first outer shell 1 and the second outer shell 2 can be separated.
[0032] Both outer casing 2 and outer casing 1 have mounting plates 3 fixedly connected to their backs. The outer walls of both mounting plates 3 have through mounting holes 18. By setting the mounting holes 18, it is easy to fix the entire device to the inner wall of the ring network cabinet or other installation positions. Both outer walls of outer casing 1 have several heat dissipation slots 19. The heat dissipation slots 19 can promote air circulation inside outer casing 1 and outer casing 2, and reduce the temperature rise of the main board 17 and various sensors.
[0033] The working principle of the intelligent monitoring and control device of this ring main unit is as follows: After the device is installed inside the ring main unit, the environmental parameters inside the unit are collected in real time through temperature sensor 5 and humidity sensor 6, and the analog signals are transmitted to the main board 17. The control module 14 on the main board 17 processes the signals to obtain real-time temperature and humidity values. The processed data can be uploaded to the remote monitoring platform through the communication module 4 to realize real-time viewing, historical records and abnormal alarms. When the temperature and humidity exceed the set threshold, the system can issue an early warning signal to remind the operation and maintenance personnel to deal with it in time and avoid equipment failure caused by abnormal environment. The connection mechanism allows each sensor and communication module 4 to be disassembled and installed independently, which is convenient for maintenance, replacement or upgrade. At the same time, through the separate setting of outer shell 1 and outer shell 2, if one of outer shell 1 and outer shell 2 is damaged, it is not necessary to replace the whole unit. Only the damaged outer shell 1 and outer shell 2 need to be replaced, which effectively saves maintenance costs.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
