SEA offers elevator dispatching control system (EDCS) of own production on the base of GSM cellular network resources.
Main (standard) functions of the offered system include:
Additional functions of the system are:
The price for SEA elevator control system project is much lower than the average one on the market. Our proposed dispatching system consists of:
Implementation of the adaptive work algorithm ensures flexible and sustainable use of all existing GSM network resources, such as its voice channel, CSD data channel and GPRS packet data channel. Thus, there is a possibility to optimize dispatch system operation in a different mode of use when GSM network is overloaded. Moreover, you can choose channels depending on their availability and suitability. Even if you have not an Internet channel or GPRS channel, the system will keep working.
SEA EDCS can be integrated into infrastructure with not only modern elevators that are managed digitally, but it is also a suitable choice for management of older relay elevators.
Embedded GSM microprocessor made by Quectel Wireless Solutions is used as a CPU and provides all the computing resources, generation, decoding and transferring of information signals in the SEA elevator group control system. Input and output ports of the STMicroelectronics auxiliary microcontroller manage executive devices and receive data from sensors. This technological "tandem" lets us achive the following:
Furthermore, using two independent and separately programmed controllers allows the most flexible and encompassing control of the whole range of remote monitoring and management tasks in real time, as well as elimination of system hangs.
A digital expansion bus with I2C and SPI interfaces can be reinforced with adapter cards that are being developed to satisfy specific customer needs. For example, you might want to install a managing board for additional contractors or automatic gathering of information from the metering device.
The economic effect from integrating our elevator control system project using microcontroller is due to:
The terminal transmits information to the dispatch center through the GSM cellular network using GPRS packet data transmission. If the network is fully or locally overloaded and, consequently, the GPRS channel is not accessible from the mobile operator or if the Internet channel is not available in the control center, then the system automatically continues to work using only the voice (the highest priority) channel. The functionality of the system is 100% preserved.
The terminal is powered by a network of alternating voltage 220 V, 50 Hz. The backup power source is a battery (battery life is not less than 5 hours).
Elevator car intercoms are vandal-resistant.
The terminal includes a built-in microphone and speaker for voice communication with the machine room.
In its operating mode "SEA ELEVATOR" terminal analyses transmitted signal combinations (in the defined control points of the serviced objct) and identifies faults, failures, attempts to interfere with the operation of the elevator and emergency situations.
When an emergency is detected a communication session with the control center takes place, during which data on sensors' statuses and the fault and message codes are transmitted.
