Description

TECHNICAL FIELD

[0001] The utility model relates to the field of elevator safety technology, especially a staircase wisdom safety device. BACKGROUND

[0002] In recent years, with the promotion of urbanization and the improvement of residents' living standards, elevators have become an indispensable vertical transportation tool in people's production and life, and people pay more and more attention to the safety, reliability, stable performance, comfort, energy saving and environmental protection, and safety of elevator riding. The conventional elevator currently only has a camera in the hall where passengers walk, and basically does not analyze the behavior data of passengers. There is a lack of collection of various behaviors of passengers during the elevator riding process. For example, if a passenger faints in the elevator during the elevator riding period, there is no timely feedback to the duty room. It can only be found after someone rides the elevator, which poses a safety risk for elevator riding.

[0003] With the development of artificial intelligence, the prior art realizes the data analysis of the complex elevator riding scene by increasing a wisdom elevator riding data collection device on the elevator, and outputs a signal to the fault signal module according to the analysis result to control the execution mechanism to perform the corresponding function. For example, the passenger data is collected by using a field video data collection platform, the posture and behavior of the passenger are actively identified by using artificial intelligence technology, an alarm is given for the abnormal behavior of the passenger, and the elevator is stopped, slowed down or a sound and light alarm is triggered when a dangerous state occurs. For example, when an old person is detected to fall suddenly in the elevator, the data collection device will collect the dangerous state signal, and timely send the data to the control system. The control system will output a signal to the fault module according to the abnormal behavior, control the elevator to slow down or stop, and simultaneously broadcast the guidance information to guide the passenger to safely leave, and improve the passenger's elevator riding experience.

[0004] However, compared with the traditional elevator riding safety device, the wisdom elevator riding safety device will perform complex calculations when actively identifying the posture and behavior of the passenger based on artificial intelligence technology, the processor will generate a large amount of heat, the temperature of the device will rise, which will affect the work and safety of the equipment. However, due to the small size of the device itself, it is not possible to equip a large size exhaust fan, which makes it difficult to ensure the safety of the existing wisdom elevator riding safety device.

[0029] Please refer to Figure 1 , Figure 1 It is the explosion drawing of the escalator intelligent safety device of the utility model; it includes:

[0030] The lower shell 10, the terminal processor 20, the temperature sensing unit 30, the upper shell 40 and the side shell 50;

[0031] The terminal processor 20 is fixed on the lower shell 10, one end of the temperature sensing unit 30 covers the terminal processor, and the other end directly contacts the inner wall of the upper shell 40;The temperature sensing unit 30 and the upper shell 40 are made of good heat-conducting material;Preferably, in the utility model, the material of the lower shell, the upper shell and the side shell is aluminum alloy material, and a plurality of heat dissipation holes are arranged on the side shell to assist heat dissipation.

[0032] The lower shell 10, the upper shell 40 and the side shell 50 are fixedly connected, forming a containing space.

[0033] When the escalator intelligent safety device is in working condition, the terminal processor 20 receives image data and position data obtained by other detection devices, and then processes and calculates the data according to the program built in the processor, and the processor generates heat in the process of processing, the temperature sensing unit 30 covering the terminal processor 20 detects the temperature on the terminal processor 20 on one hand, and the temperature sensing unit 30 forms a temperature difference with the surface of the terminal processor 20 on the other hand, and generates heat conduction effect;And the heat conduction efficiency of solid medium is much higher than that of gas heat conduction;Therefore, one end of the temperature sensing unit 30 is directly covered on the terminal processor 20, and the other end directly contacts the upper shell 40 also made of good heat-conducting material, which can quickly dissipate heat from the terminal processor 20 through solid heat conduction. Through the above setting, the overheating problem of the existing escalator intelligent safety device caused by excessive calculation can be relieved without adding a cooling fan in the small escalator intelligent safety device.
