The invention discloses equipment for reconnoitering and field sampling in a soft soil region. The equipment comprises a bearing platform, a sampling power system, a sampling device, a hole-forming device, a hole-protecting device, a power generator and a transport device, wherein the transport device is used for transporting the bearing platform to a work place; the hole-forming device is used for forming a sampling hole in the bearing platform; the hole-protecting device is arranged in the hole formed by the hole-forming device; the sampling device is used for obtaining a soil sample in a position with the distance of 15-80 cm from the lower part of the bottom elevation of the sampling hole. The invention further discloses a method for sampling by the equipment for reconnoitering and field sampling in the soft soil region. According to the equipment and the method, the reconnoitering and sampling operations can be carried out in the soft soil region with very high water content and very low bearing capacity, and the high-grade undisturbed soil sample can be obtained.

The invention discloses a programmable double fieldbus conversion interface and a method. An NCUC and Profibus-DP fieldbus conversion interface device is supported. Meanwhile, connected serial port communication equipment or internet access communication equipment can be in reliable communication with equipment supporting the NCUC or Profibus-DP fieldbus through the interface conversion device, and heterogeneous network interconnection is achieved. An STM32F103RET6 microcontroller is adopted and is a 32-bit high-performance microcontroller, a specialized Profibus-DP protocol chip is adopted, communication between user data and the Profibus-DP bus is achieved, and the processing speed is higher. The function of connecting the serial port equipment and the internet access equipment into the NCUC fieldbus and the Profibus-DP fieldbus for communication is achieved. The advantages of being high in processing speed, high in flexibility, reliable in communication and the like are achieved, the design complexity of an industrial field NCUC and Profibus-DP slave station can be reduced, the technical threshold of using the NCUC and the Profibus-DP for a user can be lowered, the development cost can be reduced, and product integration and fast product development are promoted.

The invention relates substantially to a method for computer-supported development of an overall system consisting of subsystems, in which a combination of real products and virtual behaviour models simulated in real-time are used in the phases of the right branch of the V-model, wherein the development steps ''MIL'', ''SIL'' and ''VPIL'' each comprise an environment model, a reusable multiphysicsmodel and a software, and the development step "HIL'' comprises, in addition to the environment model, another remaining physics unit for simulation of the parts of the hardware of a product that areonly virtually present. In this way, the method enables a temporally parallel and spatially divided integration and a corresponding test of components on various levels, i.e. the right-hand branch ofa V-model, which can be performed to a large extent by the system developer. Open-loop and closed-loop control functions or processes for the overall system level can already be developed in this wayfor example, even though all of the subsystems are not yet present. No parallel systems are required, on which new processes are run-in in advance. Safety-critical systems can, for example, be testedentirely in the laboratory, before a test of the real overall system is carried out in the real environment of same. Some of the key components of the development method according to the invention, such as real-time multiphysics models from the simulation and automatic system tests of development step ''HIL'', are advantageously reusable.
