The transmission motor is connected with the door body through a guide rail to realize the sliding variable speed opening and closing of the door body.
[0030] The door frame heating system can refer to Figure 2 for heating the door frame 8. The oil tank 3, the ground oil pan 2, and the door frame oil pipe 1 are connected with each other to form a circulation passage. The ground oil pan 2 has a spiral or mesh structure with a large specific surface area, is connected with a heating device (not shown in the figure), and can obtain heat through the heating device to heat the liquid in the passage. A hydraulic pump 5 is arranged in the passage to pressurize the liquid in the passage to realize the circulation flow of the liquid in the passage. The specific position of the hydraulic pump is not limited, and the application preferably is arranged between the oil tank 3 and the ground oil pan 2. The door frame heating system also includes a temperature controller 4 connected with the heating device and the circulation passage, which can detect the temperature of the liquid in the circulation passage and control the opening and closing, heating state, etc. of the heating device.

But also follow the principle of reducing heat waste, for example, the ground oil pan 2 and the ground can be provided with a heat insulation layer (not shown in the figure), to avoid heat loss.
[0032] The working mode of the door frame heating system is specifically that the temperature controller 4 controls the heating device to heat the ground oil pan 2, so that the kerosene in the circulating passage is heated. The hydraulic pump 5 makes the kerosene circulate in the circulating passage. The flowing hot kerosene can conduct heat to the door frame 8 through the door frame oil pipe 1, so that the door frame 8 is always kept at a suitable temperature, and then the sealing ring 7 on the door frame 8 and / or the sealing ring 7 on the door body 6 corresponding to the door frame 8 are also kept at a suitable temperature. The sealing ring 7 is kept in a relaxed state to play a good sealing effect, and the door gap has a certain temperature and will not freeze or frost, which can also reduce the obstacle of opening the door and facilitate the opening and closing of the door.

The central controller is used for receiving and processing task information and completing intelligent control of the cold storage door.
[0034] Specifically, the cold storage door switch brings the command to open or close the cold storage door, and the central controller receives the command and drives the transmission motor to work through the frequency converter, realizing the automatic opening and closing of the cold storage door. The photoelectric switch is arranged on both sides of the door frame and is used for detecting whether there is a person or object around the door frame. When a person or an object exists, the photoelectric switch sends a signal to the central controller, and the central controller controls the transmission motor to stop rotating, avoiding the forcible closing of the door body.
[0035] The illuminance sensor is installed on the inner side of the cold storage door and is used to detect the light intensity in the storage and transmit data to the central controller.
[0036] The display screen can display the opening and closing state of the cold storage door, the working state of the lighting lamp in the storage and the like, so as to realize information display or interaction.
[0037] The central controller can also communicate with a remote device or a mobile client through the communication module and send the opening and closing state of the cold storage door and the like to the remote device.
