Problems solved by technology

Usually m*n cables are required, and the wiring inside the surge protector is messy, which usually brings a lot of inconvenience to wiring or maintenance
[0004] In addition, it can be considered that there is only one connecting line connecting the switching value, and the connecting lines of each switching value are irrelevant to each other; if there is a fault in the line itself, there is no way to know whether it is the fault in the line itself or the lightning protection device.

Embodiment 1

[0050] see figure 1 , the present invention discloses a lightning protection device switch data acquisition monitoring system, the system includes a number of lightning protection device switch data acquisition systems 10, a server 20, a number of clients 30. Lightning protection device switching value data acquisition system 10 collects the state information of the corresponding lightning protection device switching value, which can be displayed on the display device on the corresponding lightning protection cabinet; meanwhile, the lightning protection device switching value data acquisition system 10 summarizes the collected data to In the server 20 , the operator can access the corresponding data in the server 20 through the client 30 installed remotely.

[0051] Lightning protection device switching value data acquisition system 10 comprises: a data acquisition unit arranged in a matrix, a data processing unit (can be MUC) 11, a display unit 12, an input control unit; the ...

Embodiment 2

[0063] The difference between this embodiment and Embodiment 1 is that in this embodiment, the lightning protection device includes m rows of switching values, s switching values ​​in total; the number of switching values ​​in each row is the same or different.

[0064] In this embodiment, among the switching values ​​of each row, a row of switching values ​​includes at most n switching values; the switching value D ab It is defined as the switching value of row a and column b; among them, a and b are integers, a∈[1,m], b∈[1,n].

[0065] The data acquisition unit includes m row connection lines, n column connection lines, and a switching value D ij The two ends of the i-th row are respectively connected with the line K i and the jth column connection line I j Connection; at the same time, the i-th row connection line K i or the jth column connection line I j Connect the switching value D through the corresponding first diode ij The corresponding ports of ; where i, j are ...

Abstract

The invention discloses a system and a method for switching value data collection of a lightning protection device. The system comprises a data collection unit and a data processing unit which are arranged in matrix mode. The lightning protection device comprises m rows of and n lines of switching values which are arranged in the matrix mode, and two ends of the switching values are respectively connected with corresponding row connection lines and line connection lines. The data processing unit comprises a lightning protection device failure scanning module, and potentials of the m row connecting lines and the n line connecting lines are arranged to be high potentials. The potential of a line connecting line in the n line connecting lines is sequentially arranged to be the low potential. If the low potential occurs in the m row connecting lines, and lightning protection device failures occur in a cross area between the ith row connecting line Ki with the potential to be low and present jth line connecting lines Ij. The system and the method can reduce connection cables of the switching values through matrix wiring. The system and the method can achieve line self detection and lightning protection device detection, well confirm whether the failures are line self failures or the lightning protection device failures.

Description

technical field [0001] The invention belongs to the technical field of electronic communication, and relates to a data acquisition system, in particular to a lightning protection device switch data acquisition system; at the same time, the invention also relates to a lightning protection device switch data acquisition method. Background technique [0002] SPDs include power supply SPDs and signal SPDs. SPDs are also called lightning arresters, surge protectors, surge protectors (Surge Protection Devices, SPD for short), and overvoltage protectors. Lightning protector is a device that prevents being struck by lightning through modern electricity and other technologies. It is widely used in the field of communication and electric power, and has been highly valued by everyone. [0003] There are several switches inside the surge protector. In order to make the interior of the surge protector tidy, the switches are usually arranged in a matrix. For example, m rows and n columns ...
