Suv resurslarining aniq hisobini amalga oshirish, iste’molchiga kerakli suv miqdorini o‘z vaqtida yetkazib berish bugungi kunda eng dolzarb masalalardan biridir. Hozirda gidrotexnika inshootlaridan samarali foydalanishda innovatsion texnologiyalarning zarurati oshib bormoqda. Suv hisobini raqamlashtirishda turli xil qurilmalar mavjud bo‘lib, ulardan foydalanishda energiya, iqtisodiy texnologik muammolar qatorida gidravlik jihatlar ham alohida e’tibor talab etadi. Ma’lumki, gidrotexnik inshootlarda suv sarfi hisobini amalga oshirish va boshqarishda turli xil darvoza “zatvor”lardan keng foydalaniladi. Gidravlik nuqtayi nazaridan inshootlardagi darvozalardan suv o‘tishi ancha murakkab jarayon. Suv sathini nazorat qilish va о‘lchash uchun kо‘p funksiyali qurilmalardan foydalanish zarurati tug‘iladi. Mazkur maqola gidrotexnik inshootlardan o‘tayotgan suv sarfini aniqlashni raqamlashtirishga qaratilgan. Gidrotexnik inshootlar zatvorlari ostidan o‘tayotgan suv sarfini aniqlashda ham yuqori b’efdagi, ham pastki b’efdagi jarayonlarni inobatga olib, suv hisobini raqamlashtirishning gidravlik modeli ishlab chiqilgan. Gidrotexnik inshootlar zatvorlarining yuqori va pastki b’eflarida suv sathi o‘zgarishini vertikal harakatlanadigan yassi gidrotexnik zatvor ko‘tarilishiga bog‘liq ravishda aniqlashning hisoblash usuli tavsiya etildi. Gidrotexnik inshoot zatvorlarida suv sathi va sarfini nazorat qilish hamda о‘lchashni boshqarish tizimining strukturaviy sxemasi ishlab chiqildi.

Точный учёт водных ресурсов, доставка нужного количества воды потребителю в нужное время стали сегодня актуальной проблемой. Сейчас возрастает потребность в цифровых инновационных технологиях для эффективного использования гидротехнических объектов. Существуют различные цифровые устройства для учёта воды, и при их использовании требуют внимания не только энергетические, экономические и технологические задачи, но и гидравлические. Известно, что в гидротехнических сооружениях широко применяются различные затворы для осуществ ле ния учёта и контроля расхода воды. С гидравлической точки зрения прохождение воды через затворы в сооружениях – довольно сложный процесс. Возникает необходимость использования многофункциональных приборов для контроля и измерения уровня воды. Данная статья направлена на цифровизацию процесса определения расхода воды, проходящей через гидротехнические сооружения. При определении расхода воды, проходящей через затворы гидротехнических сооружений, разработана гидравлическая модель цифровизации процесса учёта воды, принимая во внимание процессы как в верхнем, так и в нижнем бьефе. Предложен расчётный метод определения уровня воды в верхнем и нижнем бьефах затворов гидротехнических сооружений в зависимости от подъёма вертикально движущегося плоского гидротехнического затвора. Разработана конструктивная схема системы контроля уровня и расхода воды, а также контроля измерений в затворах гидротехнических сооружений.

Accurate calculation of water consumption and timely supply of right amounts of water to consumers have become urgent nowadays. Currently, there is an increasing need for innovative digitalization technologies for effective use of hydraulic facilities. As well as, there are various devices for digitalization of water metering, and when using them, among energy, economic and technological tasks, hydraulic aspects also require attention. It is known that various gate valves are widely used in hydraulic structures to generate and regulate a water flow. From a hydraulic point of view, passage of water through gates in structures is a very complex process, therefore the role of multifunctional devices controlling and measuring water levels is important. The purpose of this article is to discuss digitalization of readings of the water flowing through hydraulic structures. A hydraulic model for digitalization of water metering has been developed, taking into account processes ongoing both – in the upper and lower baffles when determining the flow of water passing under the gates of hydraulic structures. A calculation method is recommended for determining changes in water levels in the upper and lower banks of hydraulic structure gates depending on the elevation of a vertically moving flat hydraulic gate. A block diagram of a control system for monitoring and measuring the levels and flows of water in the gates of hydraulic structures, has been developed.
