The solution is characterized in that the overall structure adopts a "tower-shaped" design and is divided into two units, the bottom unit includes: power supply part, measurement, line loss metering sampling part, external bus communication part, open input and output part. The top unit includes: power supply part, ADC, metering control part, communication control part, and main control module part. The interface between the top unit and the bottom unit includes: power line, communication bus, control bus, and analog signal line.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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.

[0048] The invention provides a decentralized DTU interval unit hardware system with a temperature measurement function.

[0049] First embodiment:

[0050] Please combine Figures 1 to 3 , a distributed DTU interval unit hardware system with temperature measurement function, including a DTU box 1;

[0051] The DTU box 1 is provided with a power module 2 and a temperature measurement module 3. The power module 2 includes a main plug 21 and a power supply socket 22. The power supply socket 22 is electrically connected to a ballast module 23 through a guide. The ballast module 23 is electrically connected to a transformer module 24 through a wire.

[0052] See also Figure 2 and Figure 3 : The entire DTU box 1 is powered by the power module 2. When the main plug 21 is inserted into the power supply socket 22 inside the power module 2, the entire DTU box 1 is powered on. The unprocessed voltage JP1 enters the ballast module 23, and the ballast module 23 performs ballast processing on the current surge. After that, the current will enter the transformer module 24, and the transformer module 24 will transform the large voltage and divide it into two voltages, JP2 and JP3.

[0053] The temperature measurement module 3 includes a temperature sensor 31 and a multifunctional industrial computer 35. The temperature sensor 31 is electrically connected to a pressure sensor 32 through a wire. The output direction of the temperature sensor 31 is electrically connected to a transmitter 33 and a solenoid valve 34 through a wire. The multifunctional industrial computer 35 is electrically connected to a receiver 36 through a wire.

[0054] The side wall of the DTU box 1 is installed with a mounting plate 9 by bolts. The power supply seat 22 is located inside the DTU box 1. A cooling pipe 37 is installed on the outer wall of the power supply seat 22 and at the output end of the solenoid valve 34.

[0055] See also Figure 3 : The main plug 21 is always plugged into the power supply socket 22 for power supply. When the main plug 21 is always working, the temperature sensor 31 is continuously in contact with the outer surface of the power supply socket 22;

[0056] The temperature sensor 31 adopts wireless temperature measurement technology, which can meet the temperature of the moving contact, static contact, busbar, cable connector, transformer and other heat-prone contacts;

[0057] Communication frequency band: 470~510MHz;

[0058] Temperature measurement range: -40℃~+125℃; accuracy: ±1℃; humidity measurement function;

[0059] Starting current: minimum starting current 3.5A;

[0060] The temperature information detected by the temperature sensor 31 is transmitted by radio to the receiving terminal 36 on the multifunctional industrial computer 35 via the transmitting terminal 33;

[0061] The multifunctional industrial computer 35 is a multifunctional electric meter + temperature measurement two-in-one mode. It is installed on the high-voltage or low-voltage switch cabinet and can access 128 wireless temperature measurement points.

[0062] Multifunctional integration: temperature display + three-phase digital electric meter;

[0063] 1 Ethernet, 1 RS485, 1 LORA, I / O interface: 4DI+2DO;

[0064] Embedded installation, opening size: 92*92mm.

[0065] At the same time, the user can also set a temperature limit threshold for the temperature sensor 31 during the working process. Once the temperature detected by the temperature sensor 31 exceeds the threshold, the solenoid valve 34 will be electrically controlled to release the internal cooling medium into the cooling tube 37. The cooling tube 37 can quickly absorb the temperature of the surface of the power supply socket 22 for timely cooling treatment.

[0066] The main plug 21, the power supply socket 22, the ballast module 23 and the transformer module 24 are electrically connected in series, and the transformer module 24 can transform the voltage into two voltages, JP2 and JP3.

[0067] The power supply socket 22, the temperature sensor 31 and the pressure sensor 32 are electrically connected in series, the solenoid valve 34, the transmitting end 33 and the temperature sensor 31 are electrically connected in series, the transmitting end 33 and the receiving end 36 are connected by radio, and the cooling tube 37 adopts a spiral structure as a whole.

[0068] In this embodiment, the temperature monitoring of power equipment mostly adopts traditional temperature measurement methods, such as thermocouple temperature measurement, thermal resistance temperature measurement, handheld infrared temperature measurement, distributed photovoltaic temperature measurement, etc. However, this traditional method is manually operated and cannot achieve automatic management. It has the defects of long cycle, low efficiency, low safety factor, etc. When a fault occurs, it not only takes a lot of manpower and material resources to investigate, but also may need to re-lay the cables;

[0069] In this case, the temperature sensor 31 is a wireless temperature measurement device, which can realize on-site and remote online monitoring and early warning of the temperature change of equipment under various harsh environmental conditions, timely discover abnormal operating temperature of power equipment, and upload temperature data to the system. After reading, analyzing, and processing, it is displayed on the computer to monitor all temperature nodes in the entire station, thus greatly saving the customer's labor cost and operation and maintenance cost, realizing automatic management, and a multi-functional industrial computer 35 can be used with several temperature sensors 31. Users can install multiple temperature sensors 31 at multiple locations where they need to be installed. Using LORA communication, the device is installed in a closed cabinet, and the wireless communication distance can reach 150m, and the communication distance in an open environment can reach 500m. It greatly saves wiring costs. In addition, its communication distance and hole penetration ability are longer and stronger than 433MHz.

[0070] Second embodiment:

[0071] See also Figures 4 to 8 A positioning assembly 6 is installed inside the mounting plate 9, and the positioning assembly 6 includes a frame 61 embedded in the mounting plate 9, two first spring rods 62 are installed horizontally on the inner wall of the frame 61, and a horizontal clamping plate 63 is fixed on the opposite side of the two first spring rods 62, and a dust curtain 64 is fixed on the outer wall of the two horizontal clamping plates 63, and two second spring rods 65 are installed vertically on the inner wall of the frame 61, and the outer ends of the two second spring rods 65 are fixed with a longitudinal clamping plate 66;

[0072] An inner groove 10 is formed inside the mounting plate 9 .

[0073] The outer walls of the two transverse clamping plates 63 and the two longitudinal clamping plates 66 are both inclined, and the back surfaces of the two transverse clamping plates 63 and the front surfaces of the two longitudinal clamping plates 66 are in contact with each other.

[0074] See 4 and Figure 5 : In order to ensure that the DTU box 1 can be powered on smoothly, the user needs to insert the main plug 21 and the power supply socket 22 before powering on. Before powering on, the user needs to make the front end of the main plug 21 contact the inclined outer wall of the horizontal clamping plate 63. The user can control the two horizontal clamping plates 63 to extend to both sides by pushing hard. When extended to the limit position, the front end of the main plug 21 will contact the inclined outer wall of the longitudinal clamping plate 66, and then continue to push the main plug 21 hard to make the longitudinal clamping plate 66 extend, and finally ensure that the main plug 21 can smoothly enter the DTU box 1 and be inserted into the power supply socket 22 for powering on;

[0075] Preferably, the dust curtain 64 is made of a rubber material with good ductility, so that it can be avoided when the main plug 21 is inserted and can be reset when it is unplugged.

[0076] It also includes a lifting component 7, which includes a first rack 71 fixed on the outer wall of the longitudinal splint 66, a connecting groove 72 is opened inside the mounting plate 9, a vertical rod 73 is fixed to the inner top of the connecting groove 72, a second rack 74 is slidably connected to the outer wall of the vertical rod 73, a sleeve 75 is fixed to the outer wall of the second rack 74, a gear 76 is rotatably connected inside the connecting groove 72, a limit spring 77 is sleeved on the outside of the vertical rod 73 and located above the second rack 74, a reset spring 78 is fixed inside the sleeve 75, a telescopic rod 79 is fixed to the bottom of the reset spring 78, and a connecting rod 710 is fixed to the top of the temperature sensor 31.

[0077] Both sides of the gear 76 are meshed with the first rack 71 and the second rack 74, the upper and lower ends of the limit spring 77 are fixedly connected with the connecting groove 72 and the second rack 74, the telescopic rod 79 and the sleeve 75 are slidably connected, the top of the connecting rod 710 and the pressure sensor 32 are in contact with each other, and the connecting rod 710 and the sleeve 75 are slidably connected.

[0078] See also Figure 6 , Figure 7 and Figure 8 : When the longitudinal splint 66 rises, it will drive the first rack 71 to rise, and the rising first rack 71 will drive the gear 76 to rotate counterclockwise. When the gear 76 rotates counterclockwise, it will engage and control the second rack 74 to descend the control sleeve 75 so that the temperature sensor 31 descends and fits the outer surface of the power supply seat 22. Then, when the temperature sensor 31 is subjected to pressure, it will drive the connecting rod 710 to rise and control the pressure sensor 32 to generate an electrical signal to start the temperature sensor 31 to measure the temperature.

[0079] Understandable: From Figure 6 and Figure 7 It can be seen that the second rack 74 is limited by the vertical rod 73, so that it can be ensured that the second rack 74 can only move up and down along the vertical direction.

[0080] In this embodiment, two transversely distributed transverse clamping plates 63 and longitudinally distributed longitudinal clamping plates 66 form a rectangle, and both the transverse clamping plates 63 and longitudinal clamping plates 66 are provided with inclined surfaces of the same slope, so that when the user inserts the main plug 21, the inclined surface structure can ensure that the transverse clamping plates 63 and longitudinal clamping plates 66 are adaptively adjusted according to the size of the main plug 21. Therefore, such a design can not only position and limit the main plugs 21 of different sizes, and ensure the stability of the main plug 21 during the installation process, but also automatically reset to the closed state after power failure, which plays a good dustproof and waterproof function;

[0081] At the same time, the longitudinal clamping plate 66 moves according to the process of inserting the main plug 21. During the movement, it can drive the first rack 71 to rise and drive the second rack 74 to descend in linkage integration so that the temperature sensor 31 contacts the power supply socket 22. Only when the temperature sensor 31 is subjected to force pressure sensor 32, the temperature sensor 31 can start working. Such a design realizes the integrated operation of the temperature sensor 31 and the power-on operation. When the power is not on, the temperature sensor 31 automatically stops working. This not only ensures that the temperature sensor 31 can continue to fit in the power-on state, but also automatically starts and stops.

[0082] Third embodiment:

[0083] See also Figure 2 and Fig. 9 The power module 2 is electrically connected to the communication module 4 and the control module 5 through a wire, the power module 2 is also electrically connected to the analog module 12 through a wire, and the communication module 4 is electrically connected to the processing module 8 and the input and output module 11 through a wire;

[0084] The communication module 4 includes a parsing module 41 and a signal detector 46, the parsing module 41 is electrically connected to a filter module 42 via a wire, the filter module 42 is electrically connected to a verification module 43 via a wire, the verification module 43 is electrically connected to a detection module 44 via a wire, the detection module 44 is electrically connected to an Ethernet switch 45 via a wire, and the signal detector 46 is electrically connected to a storage module 47 and a remote operation module 48 via a wire.

[0085] See also Figure 1 and Fig. 9 :DTU mainly transmits data through wireless communication. Common communication modes include GPRS, 3G, 4G, NB-IoT, etc. DTU is equipped with a communication module 4 inside, which establishes a communication link in the area where the device is located by wireless communication with relevant base stations. The data enters the analysis module 41, the filtering module 42, the verification module 43 and the detection module 44. The data analysis and processing are mainly divided into two processes: the first step is to parse the data message and convert the digital signal into a recognizable data format. The commonly used protocols are MODBUS, DL / T646, 101, 104, etc.; the second step is to process the data, including data filtering, verification, anomaly detection, etc., to ensure the reliability and accuracy of the data;

[0086] There are two main ways of network communication: TCP / IP protocol and UDP protocol. In TCP / IP protocol, DTU establishes a connection with the server as a client, and establishes a reliable connection through three-way handshake to achieve reliable data transmission; in UDP protocol, DTU sends data in broadcast or multicast mode, which is suitable for application scenarios with high real-time requirements;

[0087] The analysis module 41 , the filtering module 42 , the checking module 43 , the detection module 44 and the Ethernet switch 45 are electrically connected in series.

[0088] The network communication in the remote operation module 48 can be through WinSock, using named pipes and mailboxes, using RPC, etc. Generally speaking, the server program can accept connection requests and other processing requests from multiple clients at the same time, and the client can also connect to several servers at the same time. Before exchanging datagrams, the data source must be calculated. The host must not only check the IP header, but also check two fields in the TCP and UPT headers: 2 bytes of IP source and 2 bytes of port number to achieve wireless remote operation.

[0089] In this embodiment, a signal detector 46 is provided to detect the network signal in real time. Once the signal is poor, all real-time data will be stored in the storage module 47. The storage module 47 contains cloud data, and the data will be transmitted to the server after the network is normal. In addition, the DTU can also implement alarm notifications through SMS or emails, etc., to promptly feedback the device status or abnormal conditions to the user.

[0090] Please refer to Figures 1 to 9 The working principle of the distributed DTU interval unit hardware system with temperature measurement function provided by the present invention is as follows:

[0091] Step S1: Insert the main plug 21 and the power socket 22 to power on;

[0092] The front end of the main plug 21 contacts the outer wall of the inclined surface of the horizontal clamping plate 63. The user pushes hard to control the two horizontal clamping plates 63 to extend to both sides. When extended to the limit position, the front end of the main plug 21 contacts the outer wall of the inclined surface of the longitudinal clamping plate 66. Then, as the main plug 21 is pushed hard, the longitudinal clamping plate 66 can be extended, and finally the main plug 21 can be smoothly inserted into the DTU box 1 and plugged into the power supply socket 22 for power supply.

[0093] Step S2: When the longitudinal clamping plate 66 rises, it drives the first rack 71 to rise, and the rising first rack 71 drives the gear 76 to rotate counterclockwise. When the gear 76 rotates counterclockwise, it engages and controls the second rack 74 to descend the control sleeve 75 so that the temperature sensor 31 descends and fits the outer surface of the power supply seat 22. Then, when the temperature sensor 31 is subjected to pressure, it drives the connecting rod 710 to rise and controls the pressure sensor 32 to generate an electrical signal to start the temperature sensor 31 to measure the temperature.

[0094] Step S4: The unprocessed voltage JP1 enters the ballast module 23 to perform ballast treatment on the voltage surge, and then the current enters the transformer module 24. After the high voltage is transformed by the transformer module 24, it is divided into two voltages, JP2 and JP3. A temperature limit threshold is set for the temperature sensor 31. Once the temperature detected by the temperature sensor 31 exceeds the threshold, the solenoid valve 34 is electrically controlled to release the internal cooling medium into the cooling tube 37. The cooling tube 37 can quickly absorb the temperature of the surface of the power supply socket 22 for timely cooling treatment.

[0095] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
