Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] like figure 1 As shown, the remote monitoring system of gas-fired power station unit includes programmable controller, industrial computer, and communication conversion module. The communication protocol of the system adopts the general MODBUS-RTU protocol. The communication conversion module is used to convert the RS232 protocol into the RS485 protocol. The programming controller is used to connect the gas concentration sensor and the smoke sensor, and upload the collected data to the industrial computer. The industrial computer compares the collected data with the built-in data alarm limit. , the industrial computer outputs an alarm command; the user accesses the industrial computer terminal through the network IP address to obtain real-time monitoring of the status of the box-type gas-fired unit.

Abstract

The invention belongs to the technical field of environment monitoring and discloses a gas generator set monitoring control system. The system comprises a programmable controller, an industrial control computer and a communication conversion module, wherein a communication protocol of the system adopts a common MODBUS-RTU protocol; the communication conversion module is used for converting an RS232 protocol into an RS485 protocol; the programmable controller is used for connecting a gas concentration sensor and a smoke intensity sensor and is used for uploading acquired data to the industrialcontrol computer; the industrial control computer is used for comparing the acquired data with a built-in data alarming limiting value; when the acquired data is greater than the highest alarming limiting value or the lowest alarming limiting value, the industrial control computer outputs an alarming instruction; and a user accesses an industrial control computer terminal through a network IP address to acquire the state of a box type gas set in real time. By adopting the gas generator set monitoring control system, monitoring and alarming of field gas concentration and smoke concentration ofthe box type gas set are realized; the gas generator set monitoring control system has a WEB publishing function based on Ethernet and realizes extra-long distance set monitoring; and the system adopts a MODBUS bus structure and has an extensible function.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and relates to a monitoring and control system for a gas-fired generator set. Background technique [0002] The existing gas generator set remote monitoring system technology is to connect the gas generator set operation monitoring parameters from the machine side control cabinet in the unit workshop to the power station control room through RS485 or RS232 communication. Observe unit parameters and electrical parameters, and send operation commands such as start, stop, closing and opening to the unit controller to realize corresponding functions. [0003] The existing gas-fired power station unit remote monitoring system has the following deficiencies in the application of box-type gas-fired power generation units: [0004] 1. There are deficiencies in the detection of the operating environment of gas-fired units. The fuel of the gas-fired unit is coal seam gas, the main compon...
