Embodiment 1

[0044] During silo storage, in order to monitor the inventory and changes of materials in the silo in real time and automatically, it is necessary to use an automatic sensing device to measure the topography of the material. Due to the characteristics of stockpiling, the currently commonly used ultrasonic stockpiling measurement methods have problems such as large measurement blind spots, limited measurement depth, and poor stability due to environmental influences. This embodiment provides a device for monitoring the appearance of the top surface of the piled materials stored in the silo, which can automatically, quickly, accurately and stably obtain the piled heights of different materials in the silo.

[0045] Combine below figure 1 Describe the specific structure of the device for monitoring the top surface morphology of silo stockpiles provided in this embodiment:

[0046] The device for monitoring the shape of the top surface of the silo stockpiles includes a two-dimens...

Embodiment 2

[0060] On the basis of the device for monitoring the top surface appearance of silo stockpiles provided in the above-mentioned embodiment 1, the present invention can also integrate the device for monitoring the top surface appearance of silo stockpiles into the overall silo storage system to provide a A system for monitoring the top surface morphology of silo stockpiles.

[0061] Such as Figure 10 As shown, it is a schematic structural diagram of the system for monitoring the top surface morphology of silo stockpiles provided in this embodiment.

[0062] The system includes a monitoring device 1 , a monitoring control device 2 and a silo 3 designed according to the device for monitoring the top surface of silo stockpiles proposed in Example 1.

[0063] The monitoring device 1 is arranged on the top of the cabin of the silo 3 , and the viewing window 31 of the monitoring device 1 faces the top surface of the piled material in the silo 3 . Because the window 31 corresponds t...

Embodiment 3

[0072] On the basis of the device for monitoring the top shape of the silo stockpiles provided in the above-mentioned embodiment 1 and the top shape monitoring of the silo stockpiles provided in the embodiment 2, the present invention provides a method for monitoring the top shape of the silo stockpiles. A method for monitoring the top shape of silo stockpiles by the system.

[0073] Those of ordinary skill in the art can understand that all or part of the steps in the processing of each step of embodiment 3 can be completed by the relevant hardware in the system for instructing the top shape monitoring system of the silo stockpile through the program, the steps in the embodiment 3 It can be stored in the readable storage medium that exists in each equipment in the monitoring device 1 and the monitoring control device 2 in the system of monitoring the top shape of the silo stockpiling material, and the storage medium can include: Read Only Memory (Read Only Memory, abbreviated ...

Abstract

The invention relates to the field of automatic monitoring, in particular to a device, a system and a method for monitoring the shape of the top surface of silo stockpilie. The device mainly comprisesa two-dimensional laser scanner, a scanning holder and a sealed box body, wherein the two-dimensional laser scanner and the scanning holder are packaged in the sealed box body, the two-dimensional laser scanner comprises a light transmission window, monitoring light of the two-dimensional laser scanner reaches the top surface of a stockpile through the light transmission window, and reflected light obtained after the monitoring light is reflected by the top surface of the stockpile returns to the light transmission window; the scanning holder drives the two-dimensional laser scanner to rotatein a third-dimensional direction; the sealed box body comprises a window, the window is located on the bottom face of the sealed box body and corresponds to a light passing window in the two-dimensional laser scanner in position, the sealed box body is sealed in an airtight mode when the window is closed, and monitoring light of the two-dimensional laser scanner reaches the stacking top face through an opening of the window when the window is opened. According to the invention, the spatial positions of the detection points at multiple positions on the top surface of the stockpile can be conveniently obtained, so that the overall morphology of the top surface of the stockpile is obtained.

Description

【Technical field】 [0001] The invention relates to the field of automatic monitoring, in particular to a device, system and method for monitoring the top surface appearance of silo stockpiles. 【Background technique】 [0002] The use of closed silos to store materials can effectively reduce the secondary pollution to the surrounding environment during the storage process, and can also reduce the waste of materials in the turnover process, avoiding the decline in the quality of materials in open-air stacking, large floor space, and difficult management issues. The materials for stockpiling and storage need to be monitored in real time, so that the system can grasp the inventory of stockpiling materials, and carry out targeted replenishment of materials according to the inventory situation. [0003] The existing technology for monitoring the top surface of the pile is mainly video surveillance, but this technology can only judge whether the pile has reached the high alert point...
