Description

Technical Field

[0001] This application relates to the field of control system technology, and more specifically, to an EPLC electronic control system for a three-dimensional parking garage. Background Technology

[0002] A multi-level parking garage is a parking system that uses mechanical equipment and electrical systems to store and retrieve vehicles. It achieves vertical stacking of vehicles through multi-level structures or mechanical devices, with the aim of maximizing parking capacity in a limited space and effectively saving ground space. The EPLC electronic control system is one of the core components of a multi-level parking garage, which typically includes a human-machine interface, a rectifier, a master EPLC controller, and at least one slave EPLC controller.

[0003] In related technologies, the wiring between all units and the control system is complex, and there is mutual interference during communication with the control system. In order to make the system run stably, for example, the patent with prior art publication number CN106843134A provides an EPLC electronic control system for a three-dimensional parking garage and its debugging method. This device greatly improves the reliability of the entire electronic control system through wiring assembly and debugging. At the same time, the EPLC controls the execution units in the three-dimensional parking garage to ensure the accuracy and precision of parking garage movement, and shortens the time of car entry and exit.

[0004] Although the existing technical solutions mentioned above have greatly improved the reliability of the entire electrical control system through circuit assembly and debugging, the EPLC controller generates a lot of heat during use. The existing technology only uses the heat dissipation vents or fans of the electrical control cabinet for heat dissipation, which is not effective and may affect the performance of the EPLC controller and reduce the stability of the electrical control system.

[0005] In view of this, we propose an EPLC electronic control system for automated parking garages. Utility Model Content

[0020] 3. Beneficial effects

[0021] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0022] (1) This application adopts a heat dissipation mechanism, which cools the air blown out by the fan through a semiconductor cooling plate, so that the cold air enters the electrical control box and cools down the EPLC controller and other circuit components. Therefore, it effectively solves the problem that the heat dissipation effect is not good in the prior art, which only relies on the heat dissipation port of the electrical control cabinet or the fan. In this way, it achieves the technical effect of preventing the EPLC controller from getting too hot during use.

[0023] (2) By setting a sealing ring and sealing strip on the inside of the door, this application keeps the inside of the electrical control box sealed when the door is closed. While ensuring air circulation inside the electrical control box, it can effectively prevent dust from entering the electrical control box and prevent dust from covering the surface of the EPLC controller and other circuit components, thus affecting the heat dissipation effect.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] Reference Figure 1 , Figure 2 and Figure 3 This application discloses an EPLC electronic control system for a three-dimensional parking garage, including an electronic control box 1. An EPLC controller 2 is disposed inside the electronic control box 1, and a door 3 is rotatably disposed on the outside of the electronic control box 1. The door 3 includes several interface terminals 31, which are connected to the internal circuit components of the electronic control box 1 through connecting wires. A heat dissipation mechanism 4 is disposed on the outside of the electronic control box 1, which is used to dissipate heat from the EPLC controller 2 and other circuit components inside the electronic control box 1.

[0033] When the equipment is in use, several interface terminals 31 are connected to the internal circuit components of the electrical control box 1 via connecting cables, enabling the EPLC controller 2 and other circuit components inside the electrical control box 1 to work normally. The heat dissipation mechanism 4 dissipates heat from the EPLC controller 2 and other circuit components inside the electrical control box 1, thereby improving the heat dissipation effect of the equipment.

[0034] Reference Figure 2 A wiring frame 11 is fixedly installed on the inside of the electrical control box 1, and several mounting bases 12 are also fixedly installed on the inside of the electrical control box 1. The EPLC controller 2 is fixedly installed on the inside of the electrical control box 1 through the mounting bases 12.

[0035] The mounting bracket 12 allows the EPLC controller 2 or other circuit components to be installed inside the electrical control box 1. The wires of each circuit component are organized through multiple openings inside the wiring frame 11 to prevent the wires inside the electrical control box 1 from becoming messy and to facilitate the inspection of the wiring by the staff.

[0036] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 An air outlet 13 is provided on the outside of the electrical control box 1. The heat dissipation mechanism 4 includes a fan 41, which is fixedly installed on the outside of the electrical control box 1 corresponding to the air outlet 13. An air inlet 14 is provided on the top of the electrical control box 1. An L-shaped pipe 42 is fixedly installed at the air outlet of the fan 41. An air inlet pipe 43 is fixedly installed at one end of the L-shaped pipe 42. The air inlet pipe 43 is fixedly installed on the top of the electrical control box 1 through the air inlet 14. Semiconductor cooling plates 44 are fixedly installed on both sides of the L-shaped pipe 42 through the mounting port 421. The cold ends 441 of the two semiconductor cooling plates 44 are both located close to the inside of the L-shaped pipe 42. Heat dissipation fins 45 are fixedly installed on the outside of the two semiconductor cooling plates 44. The two heat dissipation fins 45 are fixedly installed on the outside of the electrical control box 1 through the fixing plate 46.

[0037] When in use, the heat dissipation mechanism 4 blows air into the inside of the L-shaped tube 42 through the fan 41. The cold end 441 of the semiconductor cooling plate 44 is located inside the L-shaped tube 42, which cools the inside of the L-shaped tube 42. This cools the air blown out by the fan 41. The cold air is blown into the inside of the electrical control box 1 through the L-shaped tube 42 and the air inlet pipe 43, which cools the EPLC controller 2 and other circuit components. The air inside the electrical control box 1 enters the fan 41 through the air outlet 13, completing the air circulation.

[0038] The semiconductor cooling plate 44 and the heat dissipation fin 45 are fixed to the outside of the electrical control box 1 by a fixing plate 46, and the heat dissipation fin 45 is used to dissipate heat from the semiconductor cooling plate 44.

[0039] Reference Figure 3 A sealing ring 32 is provided at the connection between several interface terminals 31 and the door 3, and a sealing strip 33 is fixedly provided on the inner side of the door 3 corresponding to the electrical control box body 1.

[0040] Several sealing rings 32 and sealing strips 33 ensure that the inside of the electrical control box 1 remains sealed when the door 3 is closed, ensuring air circulation inside the electrical control box 1 and preventing external impurities and dust from entering the electrical control box 1, thus preventing dust from covering the EPLC controller 2 and other circuit components and affecting heat dissipation.

[0041] In summary, the EPLC electronic control system for a three-dimensional parking garage disclosed in this application, when in use, has several interface terminals 31 connected to the internal circuit components of the control box 1 via connecting cables, enabling the EPLC controller 2 and other internal circuit components of the control box 1 to operate normally. A fan 41 blows air into the inside of the L-shaped tube 42, and the cold end 441 of the semiconductor cooling plate 44 is located inside the L-shaped tube 42, cooling the inside of the L-shaped tube 42. This cools the air blown out by the fan 41, and the cold air is blown into the inside of the control box 1 through the L-shaped tube 42 and the air inlet pipe 43, cooling the EPLC controller 2 and other circuit components. The air inside the control box 1 enters the fan 41 through the air outlet 13, completing air circulation and improving the heat dissipation effect of the equipment.
