Ponsse IT applications in wood harvesting
Today, harvesters must be effective, reliable, and capable of measuring wood accurately, and they must also be easy to use and environmentally friendly. The fulfilment of these requirements can be greatly enhanced with the help of information technology.
For example, each Ponsse forest machine has the OptiControl information system with a powerful main computer, plus separate integrated computers for the control of all of the central functions, such as the drive transmission, the crane, harvester head, levers, the diesel engine, and the levelling of the cabin. All these module computers are integrated in a common network, which can be called an “intelligent overall system.” Computeraided operation makes the movements of the machine quick, accurate, and easy to control. Furthermore, numerous other automated functions, such as automatic bucking, greatly increase the efficiency and ease of use of the machine.
Ponsse harvesters are equipped with an automatic bucking system that makes it easy to obtain the best possible cutting combination from the trunks, which ensures that sawmills are delivered the right specification of timber to fill outstanding orders. This increases the added value of the wood for the plant of sawmill. This method benefits the land owner, the production plant, and the machine owner. A wireless data transfer system enables the machine to send production information to the owner of the machine and the forest company and receive new logging and cutting instructions for future logging sites.
Right place, right time
In addition to controlling forest machinery, information technology also has a central role in the management and logistics of wood procurement. The logistics of wood procurement involve the control of roundwood from the forest to the production plant. The roundwood must be delivered to the right place at the right time with minimum costs. When timber procurement logistics is efficient, raw material is carefully used, the storage period is short, empty running of timber trucks is minimised, harvesting is cost-effective, forest damage is minimal, and cooperation between various seamless.
For each stand, a representative of a forest company produces in Ponsse OptiEditor a socalled bucking file or APT file, which includes the tree species, assortments, and the length and diameter target distributions within each assortment to be logged from the stand. Prior to logging, this bucking file can be simulated in Ponsse OptiSimu with a digital group of trunks that represents the stand to be logged. This ensures that possibilities offered by the stand, and the desired logging results are in balance. operators is
Accuracy is key
The measuring device Opti4G in Ponsse harvesters measures the diameter of the trunk within an accuracy of one millimetre and the length of the trunk within an accuracy of one centimetre; it also makes an estimate of the stem curve for the current stem based on the stem bank collected during previous operations. The diameter and length distributions in each assortment as required by production plants are set in a price matrix used by the measurement device in determining the optimal cutting points for the current stem. The first estimate is run at the butt, and the cutting suggestion
