Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
Shown in Fig. 1 and Fig. 2, the sediment concentration measuring system of hog barge dredging tube of the present invention, comprises water inlet pipe 1, glass tube 2, light source, baffle plate 6 and CCD camera 7.The sidewall of described glass tube 2 upper end is provided with a water inlet 4, and the sidewall of lower end is provided with a water delivering orifice 5, and described water inlet 4 and water delivering orifice 5 are respectively equipped with valve.Described one end of water inlet pipe 1 is communicated with the dredging tube of hog barge, and the other end is communicated with described water inlet 4.Described baffle plate 6 is made up of the lighttight flat board that two are separately positioned on described glass tube 2 both sides, described two flat board angles in 90 °.Described light source is arranged on the side that described glass tube 2 is provided with described water inlet 4, and described light source is made up of two daylight lamps 3, and two daylight lamps are fixedly installed near described two flat boards respectively.Two flat boards respectively have one end and glass tube 2 wall contacts, described two flat board angles in 90 °, just refer to the extended line in 90 ° angle of two flat boards along two contact points, the light of two daylight lamps 3 by glass tube 2, and can only be radiated on described glass tube 2 with 90 ° of angles.Described CCD camera 7 is arranged on the relative side that described glass tube 2 is provided with described water inlet 4, for taking the glass tube 2 irradiated through daylight lamp 3.
Through test of many times and on-site verification, we find that CCD camera 7 must be greater than 800mm with the minor increment d of described glass tube 2 outer wall, otherwise, image processing equipment can be caused correctly cannot to process image, cause the silt content that records inaccurate.The output terminal of described CCD camera 7 is connected with described radio transmitting device by image processing equipment 8.
The sediment concentration measuring system of hog barge dredging tube of the present invention, can be integrated in an iron case 9, transport, easy to use.
When needing to measure mud silt content, open the valve on water inlet 4, gather mud from dredging tube, enter in glass tube 2.Open two daylight lamps 3, under the effect of baffle plate 6, two daylight lamps 3, as squareness light source, are radiated at the light of an angle of 90 degrees on the tube wall of glass tube 2, utilize the reflected light imaging of tube wall.The image of CCD camera shooting processes through image processing equipment 8, and result is transported to described radio transmitting device.
The water inlet 4 of glass tube 2, the valve of water delivering orifice 5, can select solenoid valve, to realize Remote water intaking and to control the water yield.Can install by the stirrer of driven by motor in glass cylinder 2, during glass tube 2 draining, the silt of sedimentation can be stirred, be beneficial to silt and discharge with water.
In plant produced activity, human eye is responsible for much important task: place and fixation workpiece, determine operation, detection outward appearance and size, determine the consistance etc. of product.In recent years, speed of production and product quality require to improve constantly, the ability of human eye has been exceeded to the requirement of speed and precision, simultaneously along with the development of the technology essential factors such as imaging, computing machine, image procossing, these tasks just more and more replace by so-called Vision Builder for Automated Inspection.Machine vision relates to multiple subject, and machine vision is automatically received by optical devices and non-contact sensor and processes the image of a real-world object, to obtain information needed or the device for control machine motion.
Vision Builder for Automated Inspection refers to by machine vision product, i.e. image collecting device, is divided into CMOS and CCD two kinds, convert collected target to picture signal, then send special image processing system to, according to pixel distribution and the information such as brightness, color, be transformed into digitized signal; Picture system carries out various computing to extract clarification of objective to these signals, then carries out the differentiation of size, shape, color etc. according to the tolerance preset and other conditions, and then controls on-the-spot device action according to the result differentiated.Like this, just the rapidity of computing machine, repeatability, and abstracting power intelligent with the height of human eye vision combines, and thereby produces the concept of machine vision.The sediment concentration measuring system of hog barge dredging tube of the present invention, has been beneficial to CCD exactly and has made a video recording the machine vision technique often adopted in this hydraulic engineering.
Taking out husky silt at the hog barge of the Yellow River reality carries on the back in construction, the distance of data transmission is generally the short-distance transmission of below hundreds of rice, from cost of development, cycle and the actual needs consideration meeting project control center monitoring, remote meter system prioritizing selection RF of the present invention receives and dispatches the wireless transmission method of mode as system.Be operated in ISM band in the market, adopt the wireless module of RF technology a lot, as STR is serial, PTR is serial, when considering the index such as wireless module transmission range, transmission accuracy rate, in conjunction with on-the-spot actual conditions, native system have employed the data transmit-receive module of SB96 type wireless data transmission module as this system.SB96 type wireless data transmission module is the wireless data sending chip CC1000 developed with Chipcon company is that its number passes a kind of low-power consumption of acp chip, two-forty, the simple wireless data transceiver module of interface, and this module is disturbed in transmission range and anti-thousand has huge superiority.
The data that the measurement of dredging tube silt content automatic measurement system obtains, by radio transmitting device, teletransmission to construction directorate data receiver treating apparatus, carry out data calculating and process after, as required, the real-time traffic of dredging tube, silt content can be printed.
