Description

Technical Field

[0001] The utility model relates to the technical field of ETC equipment, and in particular to an outdoor ETC gantry power supply and distribution safety early warning device. Background Art

[0002] The outdoor cabinet of the ETC gantry system is an outdoor cabinet used in the ETC gantry system. It is installed under the ETC gantry on the side of the highway. It is usually made of galvanized steel plate or stainless steel as the basic material and has an IP55 protection level. ETC charging equipment, communication equipment, storage equipment, etc. are installed inside. After the external power supply is directly connected to the cabinet, it provides power for related equipment.

[0003] The ETC gantry system needs to be hoisted on an open-air highway, and the integrated intelligent cabinet of the ETC gantry system is installed next to the gantry. The integrated intelligent cabinet needs to adapt to various complex climate environments. It mainly provides accommodation for gantry lane controllers, industrial switches, toll system PCs and other equipment. At the same time, it provides reliable power supply for all gantry equipment through UPS to ensure the reliable operation of key production equipment on the roadside. If a sudden power outage occurs, a general UPS can supply power for about 4 hours after the power outage. Once a power outage occurs, it needs to be actively handled to avoid the ETC gantry system from malfunctioning due to sudden power outages for a long time, because this will inevitably cause the highway ETC gantry cabinet to fail to work.

[0004] Patent document with application number 202021580733.4 discloses an emergency power supply system for highway ETC gantry cabinets, which is connected to the mains through a UPS and has an interface for an external battery pack on the UPS. When the power stored in the UPS is exhausted, the external battery pack is used to supply power, which not only ensures that the use of ETC is not affected during a power outage, but also solves the emergency situation of a long power outage, thereby maintaining the normal operation of the ETC gantry cabinet. Although the system can cope with sudden power outages, it cannot provide timely warnings after the cabinet loses power, and cannot obtain power outage information in the first place, which delays timely emergency power supply. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an outdoor ETC gantry power supply and distribution safety warning device which can give a prompt for power outages and maintain the normal operation of the ETC gantry cabinet.

[0026] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0027] like Figure 1-7 As shown, the outdoor ETC gantry power supply and distribution safety warning device includes a warning mark arranged on the cabinet 1 and a power supply circuit electrically connected to the warning mark.

[0028] The power supply circuit includes a mains access port 2, a rectifier module 3, a battery module 4 electrically connected to the rectifier module 3, and an inverter 5 connected to the battery;

[0029] The warning sign includes a support 6 and a warning light 8 arranged on the support 6 . A sinking area is arranged on the upper part of one side wall of the cabinet 1 , and a base 7 for installing the support 6 is arranged on the outer edge of the sinking area.

[0030] The outdoor ETC gantry power supply and distribution safety warning device is used to be installed on the outdoor cabinet 1 of the ETC gantry system. The power supply circuit charges the battery module 4 through the mains access port 2. When the mains power is off, the battery module 4 supplies power to the warning light 8 through the inverter 5 to light up the warning light 8, realizing power failure warning, to remind the highway ETC gantry that it is now powered by a backup power supply, and timely maintenance or backup emergency plans should be provided to prevent the ETC gantry from being unable to work due to the exhaustion of the backup power supply, affecting traffic. The utility model outdoor ETC gantry power supply and distribution safety warning device realizes power failure warning through the warning device, provides necessary support for ensuring the safe operation of the ETC gantry, and provides guarantee for the safe and smooth travel of the highway.

[0031] The support 6 is provided with a sealing gasket 61 corresponding to the base 7. The base 7 includes an annular base 71 surrounding the sinking area and a first step 72 provided at the upper end of the annular base 71. The support 6 is connected to the base 7 so that the sealing gasket 61 is pressed between the first steps 72.

[0032] Taking into account that the cabinet 1 is located outdoors and is mostly unshielded, rainproof, dustproof and moisture-proof requirements need to be met. In this embodiment, an annular base 71 that is raised relative to the sinking area is provided on the base 7, and a first step 72 is provided on the annular base 71, which is used to make the support 6 and the base 7 fit more tightly after being installed, and cooperate with the sealing gasket 61 to achieve a sealing effect.

[0033] The support 6 includes a vertical portion 62 and an inclined portion 63 connected to the lower end of the vertical portion 62 . The vertical portion 62 and the inclined portion 63 are both cylindrical. A first horizontal plate 64 is provided at the upper end of the vertical portion 62 , and the warning light 8 is provided on the first horizontal plate 64 .

[0034] A second transverse plate is disposed in the inclined portion 63 and a first screw hole 65 is provided on the second transverse plate. A second screw hole 73 matching the first screw hole 65 is disposed on the bottom surface of the sinking area. Fastening bolts 9 are passed through the first screw hole 65 and the second screw hole 73 .

[0035] In this embodiment, the first horizontal plate 64 and the vertical portion 62 are welded, and the second horizontal plate is provided with a first screw hole 65 and a second screw hole 73 for screw installation, thereby pressing the support 6 and the base 7 to achieve a better sealing effect. At the same time, the mains access port 2 is connected to the mains power supply port inside the cabinet 1 through a wire, passing through the first horizontal plate 64 and the second horizontal plate. Preferably, the mains access port 2 can be a wiring terminal.

[0036] A rib is also arranged outside the vertical portion 62. When the support 6 is connected to the base 7, the rib is located above the connection. The extended length of the rib can increase the rain resistance to a certain extent, and can also provide shelter to prevent aging caused by excessive exposure to the sun. The warning light 8 is red or yellow, and a protective cover is arranged outside the warning light 8. The battery and inverter 5 are arranged inside the vertical portion 62.

[0037] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
