Masofa o'lchagich sifatida qo'lda lazerli masofa o'lchagich oddiy masofa o'lchagichlarga nisbatan o'ziga xos funktsiyalar va xususiyatlarga ega.
The application of DISTO in mines mainly uses the combination of DISTO and domestic theodolites to form a prism-free semi-station, which is used in underground stopes to measure point position, section height, stope volume, etc.
1. O'lchov aniqligi past. Buni isbotlash uchun ma'lumotlar to'plami mavjud; 1998 yil oxirida ikkita geologik tadqiqot guruhi birgalikda to'xtash hajmini o'lchadilar va natijada bir guruh uchun 55,{3}} kubometr va ikkinchi guruh uchun 68,{5}} kubometrni tashkil etdi. Bir vaqtning o'zida bitta o'lchov qiymatini o'lchang va o'lchangan qiymatlar bir necha marta juda farq qiladi va natija yana o'lchashni davom ettirishga jur'at etmaydi.
2. Slow speed and low efficiency. The underground working environment cannot be compared with the surface environment at all. Due to the limitations of poor underground conditions, dark light, and low safety coefficient, the measurement speed is very slow and the efficiency is very low. Often a measurement point costs several times more than the usual measurement time. .
3. Although the domestic pulsed handheld rangefinder can also measure the distance, because it is ultrasonic ranging, people cannot see the position of the target point. In addition, the measuring range is too short and the accuracy is low, which greatly limits its scope of use.
DISTO dan foydalangandan keyin o'zgarishlar:
Er osti tadqiqotida faqat geodeziyachi teodolit va masofa o'lchagichni o'rnatishi kerak va maqsadli nuqta turishi shart emas. Sekin tezlik, past samaradorlik va yomon aniqlikning kamchiliklari, ayniqsa, quduq ostidagi tadqiqotlarda qizil lazer nuqtalarini ko'rishi mumkin bo'lgan qo'lda lazerli masofa o'lchagichlarning afzalliklari, ayniqsa, tadqiqotchilar tomonidan maqtovga sazovor. Qo'lda ishlaydigan lazer masofa o'lchagichni chuqur o'lchashda yakka o'zi ham ishlatish mumkin, bu juda qulay va chuqurlikdagi o'lchov yozuvlarini talab qilmasdan katta hajmdagi o'lchov ma'lumotlarini saqlashi mumkin. Er ostida qulay foydalanishdan tashqari, qo'lda lazerli masofa o'lchagich ochiq havoda qiyaliklarni o'lchash va o'lchash uchun ham ishlatilishi mumkin.
