[0016] The present application will be further described in detail below with reference to the accompanying drawings.

[0017] This application discloses an intelligent traffic guidance system.

[0018] Reference Figure 1 , Figure 2 The intelligent traffic guidance system includes a protective enclosure 1. An LED display screen 10 is fixedly installed on the outer front of the protective enclosure 1. Three doors 2 are rotatably installed on the back of the protective enclosure 1, which are used to close the three maintenance ports on the back of the protective enclosure 1. The back of the protective enclosure 1 also has inner doors 8 located inside the doors 2, and observation ports 80 are provided through the inner doors 8, allowing technicians to observe the working status of the various modules inside the protective enclosure 1.

[0019] like Figure 2 As shown, the outer wall of the door 2 has multiple rows of ventilation holes 20 that communicate with the interior of the protective box 1. A rain cover 21 is also integrally formed on the outer wall of the door 2, located above each of the corresponding ventilation holes 20. The rain cover 21 effectively prevents external rainwater from flowing into the protective box 1 through the ventilation holes 20, thus providing a better waterproof and rainproof effect.

[0020] like Figure 3 , Figure 4 As shown, the protective housing 1 has two sets of detachable placement racks 3 inside. These racks are symmetrically arranged on the left and right sides of the protective housing 1. Each rack in the same set is arranged at intervals along the height of the protective housing 1, and the racks are horizontally positioned. Multiple sets of positioning seats 5, each corresponding to a rack 3, are fixedly installed on the inner wall of the protective housing 1. Two positioning seats 5 in the same set are symmetrically arranged on the left and right sides of each rack 3. The ends of the racks 3 are inserted from top to bottom and positioned outside their respective positioning seats 5. The positioning seats 5 are used to initially position the racks 3 within the protective housing 1.

[0021] like Figure 4 , Figure 5 As shown, a first fastener 6 is fixed on the positioning seat 5 along the horizontal direction. The first fastener 6 is a bolt. A nut is welded and fixed on the outer wall of the placement frame 3 facing the LED display screen 10. The first fastener 6 is inserted on the placement frame 3, and the end of the first fastener 6 is screwed and fixed on the nut of the placement frame 3. The placement frame 3 is fixed on the positioning seat 5 through the threaded connection between the first fastener 6 and the nut.

[0022] like Figure 4 , Figure 5 As shown, the mounting bracket 3 is detachably mounted with guide rails 4 for mounting the module housing via bolts and nuts. Guide rails 4 can be DIN rails, using a snap-fit ​​installation method, supporting screwless fixing of equipment such as circuit breakers, switches, contactors, and PLCs, facilitating maintenance. The mounting bracket 3 also has through holes 30 symmetrically arranged on both the front and rear sides of the guide rails 4, spaced apart along the length of the mounting bracket 3. The through holes 30 not only ensure heat dissipation for the module housing but also serve as a cable management mechanism when the module housing is installed, by passing cables through the through holes 30.

[0023] like Figure 5 , Figure 6 As shown, multiple limiting frames 7 for mounting the module housing are slidably disposed on the placement frame 3. The bottom of the limiting frame 7 is limited on the placement frame 3, so that the limiting frame 7 can only slide along the length direction of the placement frame 3. A second fastener 70 facing the through hole 30 is threadedly connected to the limiting frame 7 in the horizontal direction. In this embodiment, the second fastener 70 is a bolt. The second fastener 70 is inserted and fixed in its respective corresponding through hole 30. The outer diameter of the second fastener 70 is adapted to the inner diameter of the through hole 30. Through the mutual insertion and cooperation of the second fastener 70 and the through hole 30, the sliding of the limiting frame 7 on the placement frame 3 can be restricted, thereby fixing the limiting frame 7 on the placement frame 3.

[0024] like Figure 5 , Figure 6 As shown, the end of the second fastener 70 is threadedly connected to a limiting pressure plate 72 located within the limiting frame 7. The limiting pressure plate 72 is slidably disposed within the limiting frame 7 along the length direction of the second fastener 70. By tightening the second fastener 70, the limiting pressure plate 72 can be pushed to move horizontally towards the LED display screen 10. The limiting pressure plate 72 can further press and fix the module housing within the limiting frame 7, thereby adapting to the limiting and fixing of module housings of different specifications.

[0025] like Figure 5 , Figure 6As shown, two limiting strips 71 are snapped and fixed at the top of the limiting frame 7. The limiting strips 71 are symmetrically arranged on the front and rear sides of the limiting frame 7. The limiting strips 71 snapped at the top of the limiting frame 7 are used to limit and fix the module housing inside the limiting frame 7, so as to restrict the module housing from being taken out from above the placement rack 3.

[0026] like Figure 5 , Figure 6 As shown, the bottom wall of the placement frame 3 has two sets of mounting holes 31 symmetrically arranged on the front and rear sides of the placement frame 3. The mounting holes 31 in the same set are arranged at intervals along the length of the placement frame 3. The mounting holes 31 are used for bolts that are set on the module housing to pass through the placement frame 3 from top to bottom. Finally, the bolts are tightened and fixed on the placement frame 3 by nuts to realize the installation and fixation of the module housing.

[0027] The implementation principle is as follows: When it is necessary to debug the module on the placement rack 3, first open the door 2 on the back of the protective box 1, and then observe the working status of each module inside the protective box 1 through the observation port 80 set on the inner door 8. After finding the module to be debugged and repaired, open the inner door 8, then unscrew the first fastener 6 from the positioning seat 5, and then take the placement rack 3 out from the positioning seat 5. At this time, the placement rack 3 to be debugged and repaired, together with the corresponding module housing, can be moved to the maintenance port, which facilitates the debugging and repair work and allows technicians to no longer be limited by the operating space inside the protective box 1, thus improving the efficiency of debugging and repair.

[0028] The guide rail 4, using a snap-fit ​​installation, supports screwless fixing of equipment such as circuit breakers, switches, contactors, and PLCs, facilitating maintenance. After the module housing is limited within the limiting frame 7, tightening the second fastener 70 causes the limiting pressure plate 72 to press and fix the module housing within the limiting frame 7, thus adapting to the installation and fixing of module housings of different specifications. Finally, the mutual insertion and cooperation between the second fastener 70 and the through hole 30 restricts the slippage of the limiting frame 7 on the placement frame 3, ensuring that the limiting frame 7 is stably and securely fixed on the placement frame 3. Finally, the placement frame 3 is placed back on the positioning seat 5, and after tightening the first fastener 6, the placement frame 3 is fixed again inside the protective housing 1. By pre-installing the module housing on the placement frame 3 at the maintenance port, and then finally installing the placement frame 3 as a whole inside the protective housing 1, the installation and positioning of each module housing is facilitated, improving the efficiency of module housing installation and debugging.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
