Problems solved by technology

[0002] At present, there are various devices for lightning protection. Some lightning protection devices do not have the fault self-monitoring function, which cannot meet the needs of modern lightning protection. Lightning protection devices with self-monitoring fault functions have emerged as the times require. It solves the problems of self-alarm, automatic display, and indoor maintenance when a fault occurs. However, this type of lightning protection device does not have large-scale, centralized, and remote intelligent monitoring functions. When the lightning protection device is damaged, it cannot pass through the digital tube in a timely and effective manner. Or the intelligent monitoring system reflects the specific fault location, which brings inconvenience to the work of maintenance and repair personnel

Embodiment 1

[0019] A signal lightning protection centralized monitoring system is composed of a PC upper computer a, a digital tube b, an intelligent monitoring host c, and a lightning protection cabinet d. The intelligent monitoring host c is respectively connected to the PC upper computer a, the digital tube b, and the lightning protection cabinet d.

[0020] The intelligent monitoring host c is composed of an online communication module 1, an information display module 2, an audible and visual alarm module 3, an 8051 CPU 4, a local number setting module 5, a data acquisition module 6 and a power supply module 7. The power supply module 7 provides power to the intelligent monitoring host c; the data collected by the data acquisition module 6 is sent to the 8051 single-chip CPU4; the local number setting module 5 sends the set local address to the 8051 single-chip CPU4; 8051 The single-chip CPU4 is connected with the online communication module 1, and the addressing signal sent by the PC...

Embodiment 2

[0027] like Figure 4 As shown, it is only necessary to replace the RS 485 module circuit with a CAN bus driver module circuit, and replace the 232 / 485 converter with a CAN bus communication interface adapter card. Through the CAN bus communication protocol design of the single-chip microcomputer, a multi-master competitive bus structure is formed. , the rest of the working principles and connection methods are the same as those in the first embodiment, and the same effects as the first embodiment can also be achieved.

Embodiment 3

[0029] like figure 2 As shown, only need to replace CPU4 of 8051 single-chip microcomputer with PIC single-chip microcomputer. For PIC single-chip microcomputer with CAN bus driver module circuit inside, it is not necessary to add CAN bus driver module circuit when performing CAN bus communication. The rest of the working principle and connection method are the same as The first embodiment is the same, and the same effect as the first embodiment can also be achieved.

Abstract

The invention belongs to the technical field of lightning protection, which more particularly relates to a centralized lightning-proof monitoring system of centralized monitoring and remote monitoring signals, which is especially applicable to a railway signal lightning-proof system. The centralized lightning-proof monitoring system comprises a PC upper computer a, a nixie tube b and an intelligent monitoring host computer c. By adopting the technical proposal, compared with the prior art, the centralized lightning-proof monitoring system has the following advantages: a monitoring staff can clearly know the working condition of a lightning protector by virtue of the nixie tube and the PC upper computer and can effectively find out and remove failures to guarantee the operation of the lightning protector in a safe state; the staff can clearly know the working condition of the lightning protector even the staff is out of the working site, therefore, the labor intensity of the maintenance personnel is reduced, and the working efficiency is improved.
