Sending current floor and up/down information to the integrated control unit via RS232 serial port with a baud rate of 9600bps. The same 7-inch STONE HMI STVC070WT-01, with a TTL UART interface to communicate with it, and the baud rate set to 9600bps.ĭC power supply provided by a 5V 1A power adapter. Hardware design of the “elevator summoning unit”
Hardware design of “floor display unit of the elevator” System hardware design (A) Outside the cabin display controlġ. This article in order to cooperate with the display control unit to demonstrate the program of MCU to illustrate. The operation control center of the elevator, generally use PLC to realize the control of the whole elevator’s electric distribution, power, fire, lighting, etc. It can control whether the whole elevator is running, which floors are not available, get the current elevator position, continuous running time, elevator load condition temperature and humidity information inside the elevator smoke alarm system condition of the lighting system, etc. Display control of control cabinet (Show in the next article) Mainly completing the functions of current floor display, floor selection & cancellation, door opening and closing, alarm, etc.ģ. This article mainly completes the display control part inside and outside the cabin.Ĭan be further divided into: “elevator floor display unit” and “elevator summon unit”. The system is mainly composed of four parts: outside the cabin display control, inside the cabin display control, display control of control cabinet, elevator integrated control unit. The control cabinet sets the panel, which can control whether the whole elevator is running and which floors are not available.The billboard inside the cabin plays or pauses according to the instruction of the display control system (no announcement is broadcast when it is not moving).Press the alarm bell when there is an unexpected situation during operation.
When arriving at the set floor, open the door after leveling and checking.The floor selection command inside the cabin can control the floor to be reached.The external summoning and internal door opening and closing commands can control the opening and closing of the cabin door.The system summons the elevator to the corresponding floor according to the summoning command (up and down command) outside the cabin and opens the cabin door after the leveling proofreading system confirms that there is no error.The elevator is a large electromechanical product composed of mechanical and electrical close contact, mainly composed of the machine room, shaft, cabin, door system, and electrical control system. System principle and composition (A) System Principle The basic logic of the integrated control unit of the elevator, in order to complete the operation control of the whole elevator system. The control cabinet setting panel, completing elevator settings, such as stopping or starting operation, certain floors without stopping. Inside the cabin advertising panel, completing the playback of video or audio advertising. Inside the cabin display control panel, completing floor selection, opening, closing, and alarming.Ģ. Outside the cabin summoning control panel, the user completes the selection of up and down floors to summon the elevator. Outside the cabin display panel, showing the floor where the elevator is located.Ģ. This article provides a set of elevator display control solutions based on the STONE STVC070WT-01 screen, including: outside the cabin display control, inside the cabin display control, control terminal three parts, you can also use it as an advertising player to use. Along with the rapid improvement of China’s economic level, elevators have long come into people’s lives and become a basic tool to be used every day.
