Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of monitoring terminal equipment, and specifically relates to a circuit breaker monitoring terminal. BACKGROUND

[0002] At present, the monitoring devices matched with 10kV circuit breakers on the market are basically designed with embedded system. The hardware adopts embedded mainboards, and the kernel mostly adopts embedded Linux operating systems. The generation of this scheme has the characteristics of industrial technology extension, that is, the manufacturers of intelligent power meters and microcomputer protection gradually develop this scheme based on the existing technical accumulation. The technical defects and deficiencies of this scheme are as follows:

[0003] 1. Unclear positioning. The reason why the positioning should be clear is that the standardization degree of products is different under different positioning, and the product deliverers are different. "Component monitoring" is at the product level, the function is relatively fixed, and it is basically matched by the circuit breaker manufacturers, so the standardization degree is high. "System monitoring" is at the management level, the number of monitoring points is uncertain, the functional requirements are uncertain, the running environment is uncertain, and the intelligent meters configured by different power distribution cabinet manufacturers and different industry application scenarios are different. At the same time, the interface protocol and application mode of the meter have great differences, and the standardization degree is low.

[0004] 2. Interface is closed. The technical route of the same products on the market determines the characteristics of closed interface, and the closed technical characteristics make it difficult for users to independently select better sensing equipment, resulting in a high threshold for secondary development of embedded software and hardware.

[0005] 3. Function is fixed. The same products on the market are basically fixed configuration combinations, such as 1~4 video monitoring, 3~9 wireless temperature measurement, 1 group of mechanical property monitoring, 1 group of chassis car and chassis car control, 1 power meter access, etc. The flexibility is not enough, which greatly limits the application in multi-industry and different specification power systems.

[0006] 4. Ability is limited. The same products on the market have embedded software and hardware architecture, high secondary development threshold, and limited edge computing capability. With the popularization of ubiquitous power Internet of Things, more and more power equipment and systems are managed intelligently in the "cloud-edge-end" Internet of Things architecture. As a monitoring terminal or communication terminal, it basically has edge computing function, and the operation work of the device side is sunk to the gateway, and the operation work of the system side is lifted to the cloud to obtain the optimal management strategy and computing efficiency.

[0033] Please refer to Figure 1 , Figure 1 The overall frame structure schematic diagram of the circuit breaker monitoring terminal provided by an embodiment of the utility model is shown.

[0034] In order to solve the technical defects and insufficient performance of the technical problems of the above-mentioned traditional monitoring device, or to achieve at least one of the above-mentioned advantages or other advantages, an embodiment of the utility model provides a circuit breaker monitoring terminal. As shown in the figure, the circuit breaker monitoring terminal comprises an industrial bus 10, an industrial control mainboard unit 20, a temperature and humidity detection unit 30, a self-organizing network acquisition unit 40, a mechanical property detection unit 50 and an internet of things unit. The industrial control mainboard unit 20, the temperature and humidity detection unit 30, the self-organizing network acquisition unit 40 and the mechanical property detection unit 50 are electrically connected with the industrial bus 10 respectively.

[0035] The industrial control mainboard unit 20 is a programmable industrial control mainboard (prior art). Compared with an embedded industrial control mainboard, the cost of the programmable industrial control mainboard does not increase, and the external interface can be freely extended through expansion. Importantly, the programmable industrial control mainboard has excellent performance in logic control, communication acquisition, etc. due to simple programming, such as ladder programming, and the threshold for secondary development is low, so that a series of products can be designed flexibly to adapt to different scenarios, thereby improving the positioning accuracy of the monitoring terminal.

[0036] In specific implementation, as shown in Figures 2-4 The industrial control mainboard unit 20 includes CPU module A1, communication module A2, communication module A3 and communication module A4 connected in sequence. Y1 of the CPU module A1 is connected to the cabinet lighting S1 through the switch KA1, Y3 of the CPU module A1 is connected to the handcart room heater S2 through the switch KA2, Y4 of the CPU module A1 is connected to the cable room heater S3 through the switch KA3, and the network port 1 of the CPU module A1 is connected to the camera SXT1; the network port 2 of the CPU module A1 is connected to the camera SXT2.

[0037] On the basis of the above, in order to solve the problem that the programmable industrial control mainboard cannot perform complex operations and is inconvenient for Internet of Things cloud communication, an Internet of Things unit can be arranged on the industrial control mainboard unit 20. The Internet of Things unit is used to assist the industrial control mainboard unit 20 in operation and Internet of Things cloud communication. The Internet of Things unit includes a touch screen OP.

The A+ interface and the B- interface of the cable room temperature and humidity sensor SH2 are connected to the P7 / 485A interface and the P7 / 485B interface of the industrial bus hub, respectively.

[0040] Further, the self-organizing network acquisition unit 40 comprises a wireless temperature measurement module WXCW and a partial discharge monitoring module JF. The A+ interface and the B- interface of the wireless temperature measurement module WXCW are connected to the P3 / 485A interface and the P3 / 485B interface of the industrial bus concentrator HUB respectively. The A+ interface and the B- interface of the partial discharge monitoring module JF are connected to the P1 / 485A interface and the P1 / 485B interface of the industrial bus concentrator HUB respectively.

[0041] The self-organizing network acquisition unit 40 mainly deals with the application of the wireless temperature measurement (or wireless partial discharge monitoring) sensor which is inconvenient for wiring and power supply. The collector of the traditional monitoring device is basically external, which is extremely inconvenient for application installation. Therefore, the self-organizing network acquisition module 40 is directly connected to the industrial control mainboard unit 20 in the embodiment, and the user no longer needs to consider the communication port resource allocation problem and the communication basic parameter configuration problem when using.

[0042] It can be understood that the wireless temperature measurement module WXCW, the partial discharge monitoring module JF, and the handcart room temperature and humidity sensor SH1 and the cable room temperature and humidity sensor SH2 can be connected to any one of the P1-P8 interfaces of the industrial bus concentrator HUB, and the present case does not limit this.

As shown in Figure 6 the A+ interface and the B- interface of the mechanical property module JT are connected to the A+ interface and the B- interface of the communication module A4; the CT1P port and the CT1N port of the mechanical property module JT are connected to the A1 port and the A2 port of the A-phase alternating current sensor CT1; the CT2P port and the CT2N port of the mechanical property module JT are connected to the B1 port and the B2 port of the B-phase alternating current sensor CT2; the CT3P port and the CT3N port of the mechanical property module JT are connected to the C1 port and the C2 port of the C-phase alternating current sensor CT3; the AD1 port and the COM1 port of the mechanical property module JT are connected to the CG1+ port and the CG1- port of the opening coil CG1; the AD2 port and the COM2 port of the mechanical property module JT are connected to the CG2+ port and the CG2- port of the closing coil CG2; the AD3 port and the COM3 port of the mechanical property module JT are connected to the CG3+ port and the CG3- port of the energy storage motor CG3; the interfaces 5V, GND, EA-, EA+, EB+, EB- of the mechanical property module JT are connected to the interfaces +V, OV, A-, A, B, B- of the angular displacement sensor BM in sequence respectively; the interfaces IN1, IN2, COM1, COM2 of the mechanical property module JT are connected to the opening and closing signal contact points of the circuit breaker QF in sequence respectively.

[0044] Further, as shown in Figure 7As shown, the A+ interface and the B- interface of the communication module A3 are connected with the A_30 interface and the B_31 interface of the chassis vehicle and the grounding blade controller QSE. Through the industrial control mainboard unit 20, the chassis vehicle and the grounding blade control, and the heater / fan control based on temperature and humidity can be directly realized.

[0045] Further, the circuit breaker monitoring terminal further comprises a power module 70. The power module 70 is electrically connected with the industrial control mainboard unit 20, the temperature and humidity detection unit 30, the ad hoc network acquisition unit 40, the mechanical property detection unit 50 and the Internet of Things unit respectively, and supplies power for the industrial control mainboard unit 20, the temperature and humidity detection unit 30, the ad hoc network acquisition unit 40, the mechanical property detection unit 50 and the Internet of Things unit. Preferably, the circuit breaker monitoring terminal can be directly connected with AC 220V power supply, and the power module 70 respectively converts the voltage to supply power for each unit module.
