Problems solved by technology

[0002] At present, most of the monitoring systems of existing ORC generator sets are controlled locally or transmitted to the control room through wired cables. The use of cable transmission increases the cost and is susceptible to interference, especially for multiple field devices at long distances. It is possible to use cable transmission for centralized control; moreover, if it is local control, when the field equipment fails, it cannot respond quickly

Embodiment 1

[0025] like figure 1 As shown, a wireless monitoring system for ORC generating sets, in this embodiment, the system consists of a field control station and a remote monitoring center, the field control station includes a programmable logic control station, a steam turbine controller, a generator controller, and supports telecommunications 3G The industrial-grade wireless router for the network, and the control logic for field instruments, actuators, pumps, valves and other equipment; the remote monitoring center includes industrial computers and wireless routers supporting telecommunications 3G networks; steam turbine controllers, generator controllers and programmable The logic control stations communicate through the MODBUS protocol, and the programmable logic control stations exchange data with field instruments, actuators, pumps, valves and other equipment through hardware I / O.

Embodiment 2

[0027] The difference from Embodiment 1 above is that further, the on-site control station sends data to and receives data from the wireless router through the programmable logic control station gateway.

Embodiment 3

[0029] The difference from the above-mentioned embodiment 2 is that, further, the remote monitoring center receives the data from the on-site control station through the wireless router, and sends the data to the on-site control station through the wireless router.

Abstract

The invention belongs to the field of ORC (organic Rankine cycle) electricity generation and particularly relates to an ORC generator set wireless monitoring system and a remote monitoring method. The system consists of a field control station and a remote monitoring center, wherein the field control station comprises a programmable logic control station, a steam turbine controller, a generator controller, an industrial grade wireless router and control logics, the industrial wireless router supports telecom 3G (3rd generation) networks, the control logics are used for equipment such as field instruments, executing mechanisms, pumps and valves, the remote monitoring center comprises an industrial control computer and a wireless router supporting telecom 3G networks, the steam turbine controller, the generator controller and the programmable logic control station realize communication through MODBUS protocols. The system has the advantages that the realization cost is lower, the anti-interference performance is high, the data transmission speed is high, and equipment of the field control station can be monitored in real time; remote failure analysis and diagnosis can be realized, the maintenance cost of the equipment is reduced, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the field of ORC power generation, and in particular relates to a wireless monitoring system and a remote monitoring method for an ORC generating set. Background technique [0002] At present, most of the monitoring systems of existing ORC generator sets are controlled locally or transmitted to the control room through wired cables. The use of cable transmission increases the cost and is susceptible to interference, especially for multiple field devices at long distances. Cable transmission may be used for centralized control; moreover, if it is local control, when the field equipment fails, it cannot respond quickly. Therefore, in the face of the above-mentioned problems existing in the control system of the ORC generating set, an effective solution is urgently needed. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the existing technology and improve work efficiency. It...
