Description

Technical Field

[0001] The present invention relates to the technical field of pipe gallery construction management, and in particular to a vehicle monitoring system for a GIL pipe gallery. Background Art

[0002] Gas Insulated Metal Enclosed Transmission Line (GIL) usually includes insulating basins, conductors and other equipment, all of which are directly or indirectly sealed in a pipeline tree composed of metal pipes and casings, and each pipe of the pipeline tree is filled with sulfur hexafluoride insulating gas at a certain pressure. The GIL pipeline corridor is a tunnel space built underground for installing GIL, so as to use GIL to transmit large-capacity ultra-high voltage current, thereby realizing the closed-loop operation of the cross-regional ultra-high voltage AC ring network.

[0003] However, the GIL corridor is located underground, which results in poor lighting conditions inside the GIL corridor. Moreover, the span of the GIL corridor is long and there are many bending areas, which limits the field of vision of workers inside the GIL corridor. Therefore, during the construction of the GIL corridor, various vehicles used to assist the construction of the GIL corridor, such as transport vehicles and tool vehicles, are easily affected by poor lighting conditions and limited field of vision when operating in the narrow tunnel space of the GIL corridor, resulting in frequent traffic accidents, which seriously affects the construction safety and efficiency of the GIL corridor. Summary of the invention

[0004] The object of the present invention is to provide a vehicle monitoring system for a GIL pipeline corridor, so as to ensure the construction safety of the GIL pipeline corridor and improve the construction efficiency of the GIL pipeline corridor.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A vehicle monitoring system for a GIL tunnel, the GIL tunnel comprising a plurality of tunnel partitions; the vehicle monitoring system comprising: a plurality of vehicle information collection units corresponding one-to-one to each tunnel partition, and a vehicle monitoring platform arranged outside the GIL tunnel; wherein each vehicle information collection unit can be connected to a vehicle signal passing through the corresponding tunnel partition; the vehicle monitoring platform is connected to each vehicle information collection unit and to each vehicle signal, and is used to dispatch each vehicle inside the GIL tunnel according to the vehicle information sent by each vehicle information collection unit.

[0007] Compared with the prior art, the vehicle monitoring system for GIL pipe gallery provided by the present invention has the following beneficial effects:

[0008] The vehicle monitoring system provided by the present invention is provided with a vehicle information collection unit inside each tunnel partition of the GIL tunnel, and the vehicle information collection unit can be used to collect vehicle information of each vehicle passing through its corresponding tunnel partition, so as to realize the vehicle monitoring system to monitor each vehicle inside the GIL tunnel in real time and comprehensively. Since each vehicle information collection unit is also connected to the vehicle monitoring platform signal disposed outside the GIL tunnel, and the vehicle monitoring platform is also connected to each vehicle signal, when each vehicle information collection unit sends the collected vehicle information to the vehicle monitoring platform, each vehicle inside the GIL tunnel is effectively dispatched through the vehicle monitoring platform, which can avoid traffic accidents and ensure that each vehicle moves safely and orderly inside the GIL tunnel, thereby facilitating the construction safety during the construction of the GIL tunnel and improving the construction efficiency of the GIL tunnel.

[0017] For ease of understanding, the vehicle monitoring system for a GIL pipe gallery provided by an embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.

[0018] See also Figure 1 and Figure 2 When the GIL tunnel 1 includes multiple tunnel partitions 11, the vehicle monitoring system provided by the embodiment of the present invention includes: multiple vehicle information collection units 2 corresponding to each tunnel partition 11, and a vehicle monitoring platform 4 arranged outside the GIL tunnel 1.

[0019] Among them, each vehicle information collection unit 2 can be connected to the signal of the vehicle 3 passing through the corresponding tunnel partition 11; the vehicle monitoring platform 4 is connected to the signal of each vehicle information collection unit 2 and each vehicle 3, and is used to dispatch each vehicle 3 inside the GIL tunnel 1 according to the vehicle information sent by each vehicle information collection unit 2.

[0020] The vehicle monitoring system provided by the embodiment of the present invention is provided with a vehicle information collection unit 2 inside each tunnel partition 11 of the GIL tunnel 1. The vehicle information collection unit 2 can be used to collect vehicle information of each vehicle 3 passing through its corresponding tunnel partition 11, so as to realize the vehicle monitoring system to monitor each vehicle 3 inside the GIL tunnel 1 in real time and comprehensively. Since each vehicle information collection unit 2 is also connected to the vehicle monitoring platform 4 provided outside the GIL tunnel 1 by signal, and the vehicle monitoring platform 4 is also connected to each vehicle 3 by signal, after each vehicle information collection unit 2 sends the collected vehicle information to the vehicle monitoring platform 4, each vehicle 3 inside the GIL tunnel 1 is effectively dispatched by the vehicle monitoring platform 4, so as to avoid traffic accidents and ensure that each vehicle 3 moves safely and orderly inside the GIL tunnel 1, so as to help ensure the construction safety during the construction of the GIL tunnel 1 and improve the construction efficiency of the GIL tunnel 1.

[0021] It should be noted that, in each tunnel partition 11 provided in the above embodiment, the vehicle information collection unit 2 may include at least two sets of vehicle information collection devices 20, and the installation positions of the at least two sets of vehicle information collection devices 20 in the corresponding tunnel partition 11 are set according to actual needs. Exemplarily, at least two sets of vehicle information collection devices 20 are respectively arranged on both sides of the axis of the GIL arranged in the GIL tunnel 1.

[0022] In order to ensure that the collection of vehicle information and its data transmission can be carried out quickly and stably, the above-mentioned vehicle information collection device 20 includes: a data switch connected to the vehicle monitoring platform 4; and a wireless bridge connected to the data switch; the wireless bridge is provided with a directional antenna for use with the vehicle-mounted antenna 31 installed on each vehicle 3.

[0023] For example, see Figure 2, the directional angle of the directional antenna is greater than or equal to 90°, such as 120°; and the signal coverage of each two adjacent directional antennas partially overlaps, ensuring that the total signal coverage of each directional antenna can fully occupy the entire GIL corridor 1, thereby avoiding missing the collection of vehicle information of individual vehicles. When the directional antenna is aligned with the vehicle-mounted antenna 31 installed on each vehicle 3 in the corresponding corridor partition, it can perform point-to-point and point-to-multipoint microwave transmission, and ensure that the vehicle information transmitted via the vehicle-mounted antenna 31 can be stably received; the vehicle information may include the vehicle's location information, running speed information, running track information, and the current external temperature information of the vehicle, etc., which can be set according to actual needs.

[0024] The above-mentioned wireless bridge can be a single-mode wireless bridge or a multi-mode wireless bridge, and its specific structure can be selected and set according to actual needs. In specific implementation, the wireless bridge uses air as the transmission medium. When it needs to perform long-distance wireless transmission, a single-mode wireless bridge can be used, but a single-mode wireless bridge can only transmit one mode signal; if two or more signal modes need to be transmitted simultaneously, a multi-mode wireless bridge should be selected, such as a dual-mode wireless bridge or a triple-mode wireless bridge. In addition, each two adjacent wireless bridges, as well as the two wireless bridges in the two sets of vehicle information collection devices corresponding to the two sides of the axis of the GIL, can be connected through a wireless MESH network signal; that is, a distributed idea is adopted, and each wireless bridge is used to build a dynamic self-organizing wireless multi-hop network, and through the bridging and roaming mode, the fast and stable data transmission of each vehicle information is realized in the GIL corridor.

[0025] It is worth mentioning that in the above embodiment, the vehicle monitoring platform 4 may include a data terminal connected to each data switch, and a communication device integrated with the data terminal. Among them, the data terminal is usually a computer display terminal, which can receive and store information of each vehicle, and convert the information of each vehicle into visual display information, so as to realize the real-time screen monitoring of each vehicle inside the GIL corridor by the vehicle monitoring platform 4. The communication equipment is connected to the vehicle telephone signal of each vehicle; the management personnel outside the GIL corridor can make scheduling decisions for each vehicle inside the GIL corridor in time according to the vehicle information provided by the vehicle monitoring platform 4, and communicate with each corresponding vehicle inside the GIL corridor through the communication equipment to perform effective scheduling, thereby ensuring that each vehicle 3 can travel safely and orderly inside the GIL corridor 1.

[0026] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
