Description

Self-adaptive lifting height adjusting system

Technical Field

The invention relates to the field of self-adaptive control, in particular to a self-adaptive lifting height adjusting system.

Background

The self-adaptive control is the same as the conventional feedback control and the optimal control, and is a control method based on a mathematical model, and the difference is that the prior knowledge about the model and the disturbance, which is the basis of the self-adaptive control, is less, and the information about the model needs to be continuously extracted in the running process of the system, so that the model is gradually improved. Specifically, the model parameters may be continuously identified based on the input and output data of the object, which is called online identification of the system. With the continuous production process, the model becomes more accurate and closer to reality through online identification. Since models are constantly being developed, it is clear that the control actions integrated on the basis of such models will also be constantly being developed. In this sense, the control system has a certain adaptability.

For example, when the system is in the design stage, the system may not perform well when being put into operation at the beginning due to the lack of initial information of the object characteristics, but as long as a period of operation elapses, the control system gradually adapts to adjust itself to a satisfactory working state through online identification and control. For example, in some control objects, the characteristics of the control objects may change significantly during operation, but the system can adapt gradually by identifying and changing the controller parameters online.

In the prior art, the kitchen is an area with a high probability of water body occurrence, so that the probability that tiles are generally paved on the kitchen floor in the household environment and slippery tiles are paved on the floors in other areas is low, and the possibility of water staining of the kitchen floor is prone to being reduced even if the tiles are paved. However, the floor contact between the kitchen and other areas, such as the hallway, is not provided with any water blocking device, or simply set with a fixed height, which is inconvenient for people to enter and exit when set too high, and affects the water blocking effect when set too low.

Disclosure of Invention

In order to solve the technical problems in the prior art, the invention provides a lifting height self-adaptive adjusting system which can clearly and effectively identify the non-pattern part in a tile imaging area of the water target related parameters based on the scene characteristics on site, and can make a corresponding self-adaptive water blocking strategy based on the identified water height, so that the automation level of the field control is improved.

Therefore, the present invention needs to have at least two important points:

(1) taking an area with tile patterns in a kitchen ground image as an area to be processed, and removing the patterns in the area to be processed to obtain a customized area with high definition and only comprising a water body target so as to improve the accuracy of subsequent water body parameter identification;

(2) the current lifting height of the water blocking cross rod is automatically controlled based on the visual recognition result of the field water body height, so that the situation that too-high obstacles are set for the people who come in and go out is avoided, and meanwhile, the kitchen water body is prevented from being leaked to other areas where ceramic tiles are not laid.

According to an aspect of the present invention, there is provided a lift height adaptive adjustment system, the system including:

the automatic water blocking mechanism is arranged at the joint of the floor of the kitchen and the floor of the entrance hall and consists of a water blocking cross rod, a height regulator and a limiter;

the water blocking cross rod is of a long strip-shaped structure, the length of the water blocking cross rod is equal to that of a kitchen door frame, the limiting device is arranged on vertical rods at the left end and the right end of the door frame, the height of the limiting device is equal to a preset height threshold value, and the maximum rising height of the water blocking cross rod is limited.

The self-adaptive lifting height adjusting system is convenient to control and has wide application. The targeted image area for clearly and effectively identifying the relevant parameters of the water target can be selected, the on-site water parameters can be effectively identified, and a corresponding water blocking strategy can be further formulated, so that the balance between convenience for personnel to enter and exit and avoidance of water leakage is achieved.

In addition, in the lift height adaptive adjustment system, the feature storage mechanism may be implemented using a DRAM chip. Dram (dynamic Random Access memory), which is a dynamic Random Access memory, is the most common system memory. DRAM can hold data only for a short time. To retain data, DRAM uses capacitive storage, so must be refreshed (refresh) once at intervals, and if the memory cells are not refreshed, the stored information is lost. (shutdown will lose data). Dynamic RAM is also comprised of a number of basic memory cells multiplexed by row and column address pins. The structure of the DRAM is simple and efficient, and each bit only needs one transistor and one capacitor. However, the capacitance inevitably has leakage phenomenon, which causes data error if the charge is insufficient, and therefore, the capacitance must be periodically refreshed (precharged), which is also a big feature of the DRAM. Moreover, the charging and discharging of the capacitor requires a process, and the refresh frequency cannot be raised infinitely (frequency barrier), which results in that the frequency of the DRAM can easily reach the upper limit, and even if the advanced process is supported, the effect is very small. With the advancement of technology and the desire of people to overclock, these frequency barriers are being solved slowly.
