Problems solved by technology
Traditional formwork construction has disadvantages such as difficulty in tower design, cumbersome procedures, poor safety protection, high cost, and low efficiency. Hydraulic climbing formwork technology has many advantages in high-rise building construction, such as convenient operation, high safety, material saving, and short construction period. advantages, making it more and more widely used in high-rise buildings
For now, scholars at home and abroad focus on hydraulic climbing formwork research mainly on engineering practical application and construction, resulting in many deficiencies in the hydraulic climbing formwork synchronization system. At present, most hydraulic climbing formwork synchronization control systems use master-slave synchronization, parallel Synchronization and other traditional control strategies, so the system has disadvantages such as prone to delay and poor anti-interference ability
It can no longer meet the requirements of high precision, low pollution and automatic control of hydraulic climbing formwork in high-rise buildings

Embodiment Construction
[0021] specific implementation plan
[0022] The hydraulic climbing formwork synchronous jacking system of the present invention adopts volumetric speed regulation (pump control direct drive). In order to realize the hydraulic climbing formwork synchronous jacking under the condition of high load and large partial load, a single controller is used, which cannot meet the needs of large areas. Therefore, the present invention proposes a distributed control strategy, using adjacent deviation coupling neural network PID control algorithm to realize the synchronous movement of multiple hydraulic cylinders. The hydraulic climbing mold synchronous jacking system consists of a hydraulic module and a control module. The schematic diagram of the system is shown in figure 1 shown.
[0023] Hydraulic module: The hydraulic module of the hydraulic climbing mold synchronous jacking system is composed of eight identical volume speed-regulating hydraulic circuits. The volume-speed regulating ...

The hydraulic climbing formwork synchronous jacking system of the present invention adopts volumetric speed regulation (pump control direct drive). In order to realize the hydraulic climbing formwork synchronous jacking under the condition of high load and large eccentric load, a single controller is used, which cannot meet the needs of large areas. Therefore, the present invention proposes a distributed control strategy, using adjacent deviation coupling neural network PID control algorithm to realize the synchronous movement of multiple hydraulic cylinders. The hydraulic climbing mold synchronous jacking system consists of a hydraulic module and a control module.
Description
technical field [0001] The invention relates to the field of automatic control, in particular to a distributed pump control adjacent deviation coupling neural network PID hydraulic climbing formwork jacking system. Background technique [0002] Nowadays, with the rapid increase of the city's population, in order to meet the living needs of residents, it is necessary to build a large number of high-rise, super high-rise buildings and large structures.
