Problems solved by technology
The lightning protection equipment in the traditional mechanical room has independent functions, only partial protection, no monitoring and collection of lightning signals, and no lightning strike information database. The staff in the mechanical room have no basis to actively analyze the lightning strike situation in the mechanical room. The quality of the lightning protection design scheme can be passively evaluated based on the loss situation, and the improvement scheme cannot be obtained immediately, and further measures can only be taken after professional lightning protection technicians visit the site for investigation, which is relatively inefficient

Embodiment 1
[0046] Example 1: The steps to counterattack decisively are as follows:
[0047] Step 1: First determine a reference zero potential point. This reference zero potential point is set at a position away from the communication tower, and embeds hot-dip galvanized angle steel as the ground electrode. The potential difference between the potential of other ground bus bars and the reference zero potential is the voltage of each ground bus.
[0048] Step 2: Generally, the direction of lightning current from outdoor to indoor is defined as positive, so the lightning current released to the outside is negative at this time, such as figure 2 shown.
[0049] Step 3: The ground network of the communication tower is connected to the ring-shaped ground network of the mechanical room. When lightning strikes the communication tower, the connection between the ground network of the communication tower and the ring-shaped ground network of the mechanical room and the voltage of each grounding...

The invention discloses a lightning protection monitoring method and system with an evaluation function, and belongs to the technical field of lightning protection. The method comprises the steps of monitoring the state of a lightning protection device through a lightning protection device state monitoring device, monitoring and collecting lightning signals through a lightning signal monitoring and collecting device, and transmitting the collected state information and lightning information of the lightning protection device to a gateway device; and forwarding the information to a diagnosis host after demodulation, and using the diagnosis host to transmit the state information of the lightning protection device and the lightning stroke information to a user terminal. According to the invention, the real-time monitoring and data acquisition can be carried out on the state of the indoor lightning protection device and the lightning signals of the indoor and outdoor signal transfer points, and the operation state of the indoor lightning protection device and the weak point of a lightning protection system can be evaluated.
Description
technical field [0001] The invention belongs to the technical field of lightning protection, and in particular relates to a lightning protection monitoring method and system with an evaluation function. Background technique [0002] In the railway signal field, all indoor and outdoor signal transfer points in the mechanical room need to be equipped with lightning protection equipment to protect indoor signal equipment from lightning strikes. The lightning protection equipment in the traditional mechanical room has independent functions, only partial protection, no monitoring and collection of lightning signals, and no lightning strike information database. The staff in the mechanical room have no basis to actively analyze the lightning strike situation in the mechanical room. The quality of the lightning protection design scheme can be passively evaluated based on the loss situation, and the improvement scheme cannot be obtained immediately, and further measures can only be ...
