Problems solved by technology

With this method, not only the monitoring cost is high, the efficiency is low, and the accuracy fluctuates greatly, but also the monitoring data is intermittent and discontinuous, which cannot reflect the change of track settlement in the whole process, dynamically and in real time
When people go to the site to observe the track manually, the storage yard needs to stop operations, which has a great impact on production scheduling and will affect port revenue
In addition, using this method, it is impossible to judge the trend of track settlement in advance. When the sudden track settlement is greater than the allowable degree of the crane, the yard needs to immediately stop the operation and adjust the track. Because this is an emergency situation, the yard cannot schedule production in advance At this time, it will have a major impact on the storage yard operation plan, and will also greatly reduce the competitiveness of the port

Embodiment 1

[0023] see figure 1 , figure 2 with image 3 , The port automated container yard is arranged with rails perpendicular to the wharf, and multiple quay bridges are installed on the wharf to operate the container ships berthing at the front of the wharf. The container is transported to the rear yard by AGV, and the rail-mounted gantry crane 1 is arranged on the yard for operation. The track 2 is installed on the storage yard, and the rail-mounted gantry crane 1 walks on the track 2. The sea side of the yard is the AGV parking area, and the land side is the truck parking area. The entire yard adopts unmanned operation.

[0024] The on-line monitoring system for track settlement of port automation container yard consists of three parts, the first part is the on-site monitoring system, the second part is the data wireless transmission system, and the third part is the rear monitoring system.

[0025] see Figure 4 , Figure 5 , Image 6 with Figure 7 , The on-site monitori...

Embodiment 2

[0029] Specific monitoring methods: see Image 6 with Figure 8 , when the yard ground 3 settles, the track 2 installed on the yard ground 3 will settle synchronously, and the reference point static level 4 at the seaside end of the track 2 is still at the initial setting position, while it is based on the same foundation as the track 2 and arranged on Each static level 51, 52 ... 5n-2, 5n-1, 5n in a row of static levels 5 on the side of the track 2 will settle, and each static level 51, 52 ... 5n-2, 5n- 1, 5n Measure the relative height difference of the static level 51, 52... 5n-2, 5n-1, 5n of each monitoring point at any time relative to the reference point static level 4, and the corresponding position of the monitoring point can be obtained. Settlement value of track 2; and real-time comparison with the tolerance of rail-mounted gantry crane 1. When the settlement of track 2 is found to be close to the tolerance of rail-mounted gantry crane 1, an early warning will be gi...

Abstract

The invention discloses an on-line monitoring system for settlement of tracks in an automatic container yard of a harbor. The on-line monitoring system comprises an on-site monitoring system, a wireless data transmission system and a background monitoring system, wherein the on-site monitoring system is composed of static force levels, data lines and wireless data acquisition devices; the wireless data transmission system is mainly composed of a signal tower, signals transmitted by the wireless data acquisition devices in the on-site monitoring system are received via a GPRS network in the signal tower, and then a wireless data receiving device in the background monitoring system receives signals transmitted by the signal tower, so monitoring data is transferred from a site to the background; and the background monitoring system comprises the wireless data receiving device, a data processing device and a monitoring center. The invention also discloses an on-line monitoring method for settlement of tracks in the automatic container yard of the harbor. The on-line monitoring system and method provided by the invention provide a novel track settlement observation mode, can greatly improve detection efficiency and reduce detection cost, and has good development prospects and market application space.

Description

technical field [0001] The invention relates to an on-line monitoring system for rail settlement, in particular to an on-line monitoring system and method for rail subsidence applied to a port automated container yard. Background technique [0002] In order to reduce operating energy consumption and improve operating efficiency, the current port automated container yards use rail-mounted gantry cranes that can be operated unmanned without a cab. The rail-mounted gantry cranes walk on rails on the stacking yard. Since the rail-mounted gantry crane contacts the track through the wheel tread of the traveling mechanism of the cart, it has high requirements for track precision, especially for the settlement control of the track. It is necessary to ensure that the height difference between the two tracks is not greater than ±10mm. In order to reduce the project cost, the track foundation of many port automated container yards does not use the pile foundation structure, but the s...
