Wireless remote laser gas and dust synchronous online detector

Abstract

The invention relates to a wireless remote laser gas and dust synchronous online detector. The detector can be controlled remotely and wirelessly and can be used to carry out laser synchronous online detection and analysis on gas and dust. The detector is mainly composed of a laser emitting system, a laser receiving system, a signal processing system, and a remote control system. The laser is converted into parallel collimated light beams by a lens; the light beams go through the gas and dust to be detected, reaches a laser receiver, and is converted into an electric signal through photoelectric conversion; the electric signal is amplified and is converted into a digital signal, the digital signal is processed in a signal processing system, the detection modes for detecting the gas and dust can be switched freely so as to detect the gas and dust online in real time; the detector is embedded into a wireless network (3G/4G), thus the detector can be controlled remotely, and a set-point control program is written to control remote target equipment to carry out data reading, and behavior and function automatic adjustment. The detector can be used in many occasions, and is capable of generating great economic profits or other beneficial results.

Description

Technical field [0001] The invention relates to a wireless network remote control instrument, in particular to a wireless remote laser gas and dust synchronous online detector. Background technique [0002] In many industrial occasions, the main control room and the field equipment are far away from each other. Generally, the measurement results are transmitted only through 4-20mA between the two, and it is impossible to debug the equipment or perform other operations, which brings great inconvenience to the work. For example, for the top of a chimney that is hundreds of meters high, it will be troublesome and dangerous for the staff to go up and debug the equipment. There are also some flammable, explosive, toxic and harmful occasions that are not suitable for long-term staff stays, such as near gas warehouses, hazardous areas in oil refineries, hazardous areas in chemical plants, etc. The equipment in these areas needs to be controlled by networking. The traditional wired conn...

Problems solved by technology

[0002] In many industrial occasions, the distance between the main control room and the field equipment is very far, and the measurement results are generally only transmitted through 4~20mA between the two, and it is impossible to debug or perform other operations on the equipment, which brings great inconvenience to the work.

For example, at the top of a chimney that is hundreds of meters high, it will be very troublesome and dangerous for the staff to go up and debug the equipment

There are also some flammable, explosive, toxic and harmful places that are not suitable for staff to stay for a long time, such as near gas warehouses, hazardous areas of oil refineries, hazardous areas of chemical plants, etc. The equipment in these areas needs to be controlled by network

The traditional wired connection method has great disadvantages, especially in long-distance transmission, not only the cost is high, the wiring is troublesome, and the transmission distance is limited

Generally, the transmission distance of the network cable is within 100 meters, and the farther can not be satisfied, unless the optical fiber connection is used, and the optical fiber connection will increase the equipment, increase the cost, and also increase the workload of wiring

However, the switching system module and software system of laser absorption and laser scattering have not been reported so far.

Moreover, in many industrial occasions, gas analysis and dust monitoring are independent instruments and independent engineering systems, and the cost of instruments, operation costs, and maintenance costs are relatively high.
