1.“LMM B-COUNTER” online automatic steel bar counting and separation system can effectively subtract manual works, which is the only national automatic counting and steel-separation system used online with application performance. The system has applied national patent for invention. The patent number is 201210002751.8. The system software has registered software copyright with the number of 2011SR096660.
2.With unique technologies in multi-target tracking, fault tolerance and multilevel tracking, the system can effectively and inevitably prevent wrong recognition and leaking recognition. The system is excellent in anti-shaking performance (as for small-specification bars), fast in counting speed and saving in time.
3. It can count and split steels visually. When the rated number is full, it can automatically stop chain bed. The definite steel-separation position will be given through overlapping real-time video and computer image. The workers can split steel in correct position according to the guidance in steel-separation position. It can observe the steel-separation process and judge the rights and wrongs in steel-separation operation. The system can achieve automatic steel-separation.
4. Automatic steel-separation software system and mechanical device under high-precision servo control has been operating for 36 months without faults. The steel-separation precision and recognition rate are high.
4. LMM3000 retesting and counting system for bundle bars
On the request of various departments of enterprise management, quality, inspection, sales and warehouse, we have developed LMM3000 retesting and counting system of bundle bars.
On the basis of accurate counting of LMM1000 system, the system uses LMM3000 system (the system is used in secondary inspection and counting with static image recognition technology in bar sides) to elevate the pile-separation accuracy by 1-2 order of magnitude. LMM3000 system is divided into two models: LMM3000-l online retesting and LMM3000- ll handheld review.
- The system is simple to use, high in accuracy and heavy in storage content, which can retest online in real time and recheck the number each bundle. After finishing counting, store the picture and relevant data (date, checker, address, steel number, furnace number, production shift, etc.) to retest system.
- Display counting quantity obviously; in case of wrong alarming upon counting, the system can prompt manual intervention.
- Set up local display system (indoors) and portable display system. Technical Parameter
- Because of the system is measured and rechecked manually during counting process, the accuracy reaches 100%after manual correction.
- lt may carry out data transmission with original weighing system.
- It may add automatic counting system in weighing position, and recheck the bars after separation.
