Description

Technical Field

[0001] The invention relates to the technical field of traffic signal control, and in particular to a centralized coordinated road traffic signal all-optical communication controller. Background Art

[0002] With the advancement of science and technology and the rapid development of modern cities, the problem of urban traffic congestion is becoming more and more serious, especially during the rush hours in the morning and evening. Various motor vehicles and non-motor vehicles passing through road intersections are prone to competing with each other for the right of way and causing traffic accidents. Therefore, all-optical communication controllers are used to improve the control ability of traffic lights at road intersections. The existing road traffic signal controller usually uses a single-chip microcomputer as a microprocessor and RS232 serial communication. It controls and runs according to the set fixed parameters. The host computer remotely controls the intersection signal machine to control the light color and time of the road signal light.

[0003] The control machine will be installed at the intersection to monitor traffic signals at all times. Since the control machine is installed outdoors, it will be affected by the external environment. When the environment is humid, moisture will enter the control box and cause damage to the internal electronic components. Existing desiccant is generally placed to ensure the dry environment in the control box. After the desiccant is completely used, it is necessary to regularly take out the used desiccant and put in new desiccant, which increases labor costs. Due to the constant changes in the environment, the desiccant usage status is inconsistent during regular replacement, which will result in the desiccant being replaced before it is completely used, increasing the loss of the desiccant.

During the first stroke, the sliding plate 2 drives the rotating assembly to close the sealing assembly. When the desiccant absorbs moisture and increases its own weight and moves to the second stroke, the sliding plate 2 drives the unlocking assembly to move and open the sealing door 13 to allow the used desiccant to be discharged from the control box 1. The desiccant's own weight increases after absorbing moisture, so that the sliding plate 2 moves down, and the sealing door 13 is opened by the unlocking assembly to discharge the used desiccant from the control box 1. Then, the sealing door 13 is driven to close by the electric telescopic rod 7, and the switching assembly is driven to rotate at the same time to open the sealing assembly and transport the unused desiccant to the sliding plate 2, so that the sliding plate 2 moves down, and the rotating assembly is driven to rotate to passively drive the sealing assembly to close, thereby realizing automatic loading and unloading of the desiccant, drying the control unit in the control box 1, and increasing the service life of the control unit.

[0022] In an embodiment further provided by the present invention, the seal includes two guide plates 31 fixed to the bottom of the fixed plate 11, a sealing plate 32 is slidably arranged inside the guide plate 31, an abutment spring 33 is arranged inside the guide plate 31, a first wedge plate 34 is slidably arranged outside the sealing plate 32, and a snap-in groove 35 adapted to the first wedge plate 34 is opened in the guide plate 31.

When the sliding plate 2 slides during the first stroke, the guide block 44 slides in the linear groove. When the sliding plate 2 moves into the spiral groove, the sliding plate 2 drives the rotating rod 41 to rotate, so that the rectangular rod rotates, driving the connecting rope 43 to reel up, so that the first wedge plate 34 moves out of the clamping groove 35, and drives the sealing plate 32 to move down for sealing through the abutment spring 33.

[0025] In the embodiment provided by the present invention, the unlocking assembly includes a fixed tube 51 fixed in the control box 1, a second wedge plate 52 is slidably arranged in the fixed tube 51, a pressure plate 53 is slidably arranged in the control box 1, the pressure plate 53 is fixedly connected to the second wedge plate 52 by a pull rope 54, and a return spring 55 is provided on the outer sleeve of the pull rope 54.

[0026] In the embodiment provided by the present invention, a switching component is also included. When the sealing door 13 is closed, the sealing component is opened by the switching component to transport the unused desiccant to the sliding plate 2. The switching component includes an elastic telescopic rod 61 rotatably arranged outside the guide plate 31, one end of the elastic telescopic rod 61 is rotatably connected to the sealing plate 32, and the other end of the elastic telescopic rod 61 is rotatably connected to the limiting tube 62, and the limiting tube 62 is slidably arranged in the control box 1.

[0027] Furthermore, an abutment plate 63 is slidably disposed in the limiting tube 62, and a connecting rod 68 is fixedly connected to the abutment plate 63. Both ends of the connecting rod 68 extend outside the limiting tube 62. A limiting groove 69 adapted to the connecting rod 68 is provided in the control box 1, and the bottom of the limiting groove 69 is an inclined surface (such as Figure 4 As shown in the figure, when the connecting rod 68 moves to the bottom of the limiting groove 69, the abutment plate 63 is driven to move into the limiting tube 62, so that the abutment plate 63 moves out of the one-way plate 65, thereby realizing the unlocking between the abutment plate 63 and the one-way plate 65.

[0028] Furthermore, the switching assembly also includes a connecting plate 64 fixed on the sealing door 13, one side of the connecting plate 64 is rotatably connected to a one-way plate 65, and one side of the connecting plate 64 is fixedly connected to a convex plate 66 that contacts the one-way plate 65, a tension spring 67 is arranged in the control box 1, and a torsion spring is fixedly connected to the one-way plate 65, and the torsion spring is fixedly connected to the connecting plate 64, so that the one-way plate 65 remains perpendicular to the connecting plate 64, and under the limitation of the convex plate 66, the one-way plate 65 only rotates downward.

[0029] In the solution further provided by the present invention, an electric telescopic rod 7 is fixedly connected to the control box 1, and the two ends of the tension spring 67 are respectively fixedly connected to the outer shell of the electric telescopic rod 7 and the connecting plate 64. The electric telescopic rod 7 is not in contact with the connecting plate 64 in the initial state. When the electric telescopic rod 7 is working, the telescopic rod is extended and contacts with the connecting plate 64, and then the connecting plate 64 is driven to move downward, thereby driving the sealing door 13 to seal the control box 1, and then the electric telescopic rod 7 is closed, so that the telescopic rod is retracted to the initial state.

[0030] In the present invention, two baffles 14 are further included, wherein one baffle 14 is fixed between the fixing plate 11 and the limiting plate 12 , and the other baffle 14 is fixed between the limiting plate 12 and the control box 1 .

[0031] When in use, when the limit plate 12 and the desiccant in the control box 1 absorb moisture and cause the weight to increase, the sliding plate 2 moves downward, driving the support spring 47 to compress, and the sliding plate 2 moves downward to press the pressure plate 53 downward (such as Figure 7 As shown), the pull rope 54 pulls the second wedge plate 52 out of the sealing door 13, thereby compressing the return spring 55, and then the tension spring 67 pulls the connecting plate 64 upward, driving the sealing door 13 to move synchronously, thereby opening the sealing door 13 and discharging the used desiccant out of the control box 1; After the desiccant on the sliding plate 2 is reduced, the supporting spring 47 drives the sliding plate 2 to move upward, so that the guide block 44 slides in the guide groove 45, thereby rotating the rotating rod 41, thereby loosening the connecting rope 43, and the first wedge plate 34 is pushed outward by the elasticity of the limit spring 36 to clamp the sealing plate 32; When the connecting plate 64 moves upward, it drives the one-way plate 65 to move synchronously (with Figure 4 As a reference), when the one-way plate 65 contacts the abutting plate 63, it continues to move upward to rotate the one-way plate 65 until the one-way plate 65 moves above the abutting plate 63, and then the one-way plate 65 is reset by the torsion spring. When the desiccant is emptied, the sliding plate 2 moves to the uppermost initial state, driving the electric telescopic rod 7 to move, so that the output shaft moves downward to contact the connecting plate 64 and pushes the connecting plate 64 downward, so that the bottom sealing door 13 moves synchronously, thereby closing the sealing door 13; When the connecting plate 64 moves downward, the one-way plate 65 is driven to move synchronously, thereby contacting the abutting plate 63. Due to the limitation of the convex plate 66, the one-way plate 65 pushes the abutting plate 63 to move synchronously, driving the limiting tube 62 to move downward, thereby causing the elastic telescopic rod 61 to rotate, causing the sealing plate 32 to move upward, allowing the unused desiccant to enter the sliding plate 2 through the through hole. The sealing plate 32 moves upward to pull the rectangular rod 42 to move upward in the rotating rod 41 synchronously, causing the abutting spring 33 to be compressed. When the abutting plate 63 moves downward, it drives the connecting rod 68 to move synchronously, thereby causing the connecting rod 68 to move in the limiting groove 69. When the connecting rod 68 moves to the bottom of the limiting groove 69, it pushes the abutting plate 63 to move into the limiting tube 62, causing the abutting plate 63 to move out of the one-way plate 65. The increase of desiccant on the sliding plate 2 causes the sliding plate 2 to move downward due to gravity, thereby causing the guide block 44 to slide in the guide groove 45. When the guide block 44 moves to the spiral groove, the guide block 44 continues to move to drive the rotating rod 41 to rotate, and the connecting rope 43 is wound up, so that the first wedge plate 34 moves out of the sealing door 13, and then the sealing plate 32 is pushed downward by the abutment spring 33 to close the fixed plate 11, thereby realizing automatic discharge and loading of the desiccant.

[0032] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
