In the preferred embodiment, taking the example that the goods 8 outside the refrigerator are conveyed into the refrigerator, when the goods 8 enter the field of view of the first binocular camera 3, the first binocular camera 3 can detect the outer dimension of the goods 8 through the image recognition technology, determine the boundary dimension of the goods 8 in the transverse direction and the vertical direction and the length dimension of the goods 8, and then calculate the time when the goods 8 reach the first opening and closing door 1 and the time when the goods 8 integrally pass through the first opening and closing door 1 by combining the transmission speed of the conveyor belt 7, so that the opening and closing time and the opening amplitude of the first opening and closing door 1 can be determined; correspondingly, the opening and closing time and the opening amplitude of the second opening and closing door 2 can be determined according to parameters such as the thickness of the partition wall 6 of the refrigeration house, the speed of the conveyor belt 7, the vertical dimension of the goods 8 and the like.
Further preferably, the two binocular cameras in the preferred embodiment can establish a three-dimensional space coordinate system at the positions of the two binocular cameras to determine the transverse boundary of the goods 8 on the conveyor belt 7, so that the specific opening position of the opening amplitude can be further determined on the premise of determining the opening amplitude of the first opening and closing door 1 so as to correspond to the goods 8 on the conveyor belt 7, and collision accidents caused by the fact that the positions of the goods 8 do not correspond to the opening amplitude of the first opening and closing door 1 are prevented; further preferably, in the preferred embodiment, the detection of the two binocular cameras is double redundancy detection, and the accuracy of data acquisition is ensured by adopting a multi-sampling mode.
Further preferably, the bottoms of the two sides of the refrigerator partition wall 6 corresponding to the goods 8 on the conveyor belt 7 are respectively provided with laser detection units which are respectively arranged in two groups on one side of the two wall surfaces of the refrigerator partition wall 6 and used for monitoring whether the goods 8 reach and pass through the refrigerator partition wall 6, so as to assist in controlling the opening and closing of the first opening and closing door 1 and the second opening and closing door 2; more specifically, in the preferred embodiment, each group of laser detection units respectively arranged at two sides of the partition wall 6 of the refrigerator comprises two pairs of laser detection devices 5, the two pairs of laser detection devices 5 are arranged at intervals along the moving direction of the conveyor belt 7, preferably an inner side laser unit close to the partition wall 6 of the refrigerator and an outer side laser unit far away from the partition wall 6 of the refrigerator, and each pair of laser detection devices 5 comprises two pairs of laser detection devices oppositely arranged at two sides of the conveyor belt 7; further, each pair of laser detection devices 5 is in a communication state in a normal state, when goods 8 are transported on the conveyor belt 7, the goods 8 can separate the laser detection devices so as to be in a disconnection state, and the conversion of the process can be detected by the control system and generate corresponding control instructions; further preferably, the two pairs of inner laser units are preferably disposed corresponding to the two opening and closing doors such that the door surfaces of the two opening and closing doors are respectively on the same plane as the corresponding inner laser units.
Preferably, taking the case that the goods 8 outside the refrigeration house are conveyed into the refrigeration house as an example, when the front end of the goods 8 reaches the front of the first opening and closing door 1, the goods 8 cuts off the outer laser units, the outer laser units send information to the control system, the control system generates control instructions, the first binocular camera 3 is opened, the position information and the size information of the goods 8 are detected by the control system, the goods 8 cuts off the inner laser units, at the moment, the goods 8 are about to enter the first opening and closing door 1, the control system can judge whether the opening amplitude of the first opening and closing door 1 is in place at the moment, and if the opening amplitude of the first opening and closing door 1 is not in place, the control conveyor belt 7 is generated to brake so as to avoid collision accidents; further, when the inner laser units are communicated again, the goods 8 are indicated to pass through the first opening and closing door 1 integrally, so that the control system generates a control instruction to enable the first opening and closing door 1 to be closed; accordingly, when the internal line laser near the second opening and closing door 2 is again communicated, it means that the article 8 has entirely passed through the second opening and closing door 2, and at this time, the second opening and closing door 2 is controlled by the control system. Through the above process, the intelligent opening conveying door in the preferred embodiment of the invention can complete automatic conveying of the goods 8 from outside the refrigerator to inside the refrigerator, and the opening amplitude of the refrigerator conveying door in the above process is matched with the size and the position of the goods 8, so that the loss of cold in the opening and closing process of the conveying door is reduced as much as possible, and the opening and closing and controlling process of the refrigerator conveying door can refer to the logic control relation schematic diagrams shown in fig. 4 and 5.
Further, when the goods 8 are transferred from the refrigerator to the refrigerator, the automatic transportation of the goods 8 and the automatic control of the conveying door can be realized through the control process, namely, the boundary size and the position information of the goods 8 are detected through the second binocular camera 4, the opening amplitude of the second opening and closing door 2 and the opening amplitude of the first opening and closing door 1 are determined, and whether the goods 8 completely pass through the second opening and closing door 2 and the first opening and closing door 1 or not is determined through the two groups of laser detection units respectively, so that corresponding control instructions are generated to control the two opening and closing doors 2 to close and restore the default positions, and the process of delivering the goods 8 is completed.
Further preferably, the conveyor belt 7 in the preferred embodiment is provided with an emergency braking device, which is connected with the control system, when the inner laser unit detects that the goods 8 are close to the first opening and closing door 1 or the second opening and closing door 2, but the first opening and closing door 1 or the second opening and closing door 2 is not opened in place, the control system can control the conveyor belt 7 to stop driving through the emergency braking device so as to prevent the goods 8 from colliding with the first opening and closing door 1 or the second opening and closing door 2, ensure that the goods 8 and the two opening and closing doors are not damaged, and then restart the conveyor belt 7 after the opening and closing doors are opened in place, and finish conveying the goods 8.
