Current situation:Due to some small gates being located in remote areas and not designed with electric control, remote operation and control can only be achieved after these gates are converted to electric control,
The transformation into electric control requires solving the power supply problem. Setting up power supply lines is currently not feasible due to long distances, high costs, and poor economic benefits. The gate can only be opened and closed by the manager every time
Run to the scene and manually open and close. The operation is inconvenient and not timely. The HHKZ-T remote gate control system we designed only requires a small amount of investment to achieve remote operation and control.
Achieving the goal:Remote computer operation of gates, real-time observation of gate working status and on-site conditions.
Implementation method:The power supply is provided by a power system composed of solar energy, batteries, charging management equipment, etc; The power source and control part are composed of DC motors, contactors, etc; By sensors, controllers
DTU、 Control boxes and other equipment complete on-site signal acquisition, control, and uploading; Communicate wirelessly with the central control room via GPRS.
The system design follows the following principles: simple and reliable control system, high redundancy, flexible operation, and easy maintenance. Fully reflect the progressiveness of the system,
The system configuration and equipment selection are in line with the rapidly developing characteristics of computers, making full use of advanced technologies in the fields of computers and networks to achieve the overall performance of the system at a contemporary advanced level. The human-machine interface has powerful functions,
Adopting a touch screen, the operation is convenient, simple, and intuitive. Adopting a modular structure design for easy maintenance and system upgrades. The structural design is novel and beautiful, fully reflecting progressiveness. The design and manufacturing of the system are complete
Compliant with regulations and relevant national standards. The selected equipment has high reliability, adapts to harsh environments, and has strong lightning protection and anti-interference capabilities for the system. According to the requirements of remote operation, various monitoring and protection measures have been added to the system design
measures. For example, motor operating current, battery voltage, solar charging status, motor overload protection, motor underload protection, power abnormal protection, gate abnormal movement protection, etc.
In order to facilitate on-site installation and debugging and be applicable to different gate structure characteristics, the system design fully utilizes computer intelligence to enable the system to automatically identify and remember gate motion parameters,
Individual setting parameters can be easily inputted through the touch screen, achieving correct control and reliable protection. It also brings great convenience to installation and debugging.
Command controller:Control the upper and lower limits of the gate.
Real time monitoring of battery voltage, solar panels, and other on-site operating conditions. When the battery voltage drops below 22V, it is prohibited to trip and report low battery voltage; During the process of opening the gate, if the voltage drops to 20V, the gate immediately stops. After the battery voltage reports low, it must wait until the voltage rises above 22V before resuming operation.
