Outdoor advertising boxes are widely distributed and scattered. Distribution throughout the country, the estimated initial control point is about 70, the system requires a system monitoring host can effectively control 70 control points of the light box timer switch and status display and fault alarm, each control point ads The number of lamps varies, up to 400 units. The power of each lamp is about 40W.
system introduction:
This plan was formulated by our company based on the above control requirements. After detailed formulation of the technical department, it was decided that the control system should use the mature system in the current market: GSM remote control system. The control software installed on the host computer gives control commands and monitors the running status. After the command is released, it passes the Siemens GSM control command to 70 controlled points. After the controlled point extension receives the signal, it recognizes the command and executes the action. The operating status is transmitted back to the host server in the form of information. After analyzing the GSM command, the host server displays the status of the controlled point.
The core components of this system are all imported Siemens components. The core technology of our company is quite mature, and the key weak current control technology and signal conversion technology have passed rigorous tests at home and abroad. The communication signal adopts the second-generation communication technology "GSM mobile communication technology" that is commonly used in the international market to realize wireless remote control and monitoring, which is convenient and quick. The system adopts a modular design. Through the monitoring software, detailed alarms can be provided to indicate the specific distribution of alarms. The failure of a single device does not affect the operation of other devices. The system has scalability and can freely expand the number of controlled points.
System functions:
1: Automatic switch (timing control)
This system supports the user to use the software to control the controlled light box regularly. For example, if the software edits the message “Open 8:00 every day, 20:00 OFFâ€, this command will be sent to all the controlled points by command, and the control point will execute 8:00 open, 20:00 off orders, unified implementation of this command every day, regular time period can be changed.
2: Manual switch
The administrator can click the All button on the monitoring software to open all 70 control points or open each button one by one. If you click the Jinan Open button, the software will immediately send the open information to the Jinan Controlled Branch Office. Jinan is controlled by the extension. The opening operation will be executed immediately, and the power-off detection provided by the extension will detect the on/off of the external circuit, and the relevant information will be fed back to the monitoring software. The software will display the status of the controlled point in real time.
