[0027] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0028] The prior art (CN104637363A) discloses a fracturing acidizing simulation training system and simulation method, which includes a control system, a liquid storage tank model, a tank manifold model, a high and low pressure manifold model, a sand concentrator model, a wax ball manifold model, a liquid nitrogen truck model, a surfactant pump model and a fracturing wellhead, and the control system includes a teacher console, a ring screen projection system, a fracturing truck remote console, a fracturing truck local console, a sand mixing truck remote console, and a sand mixing truck local console. The ring screen projection system is connected to an image fusion machine, and the consoles are connected to a parameter computer through an RS232 communication interface. The beneficial effects of the present invention are: building a simulation training platform for fracturing acidizing technology, which not only meets the requirements of theoretical teaching, but also provides practical hands-on simulation training operations, displays the on-site scene in a large-screen projection mode, and combines highly simulated on-site sound effects to make trainees more familiar with on-site equipment, reduce misoperation, improve training effects, and reduce training and maintenance costs.

[0029] However, the prior art (CN104637363A) aims to simulate the process of fracturing and acidizing, and mentions the remote control console of the fracturing truck and the local control console of the fracturing truck, but there is no direct connection between the fracturing truck and the digital twin. Therefore, the prior art (CN104637363A) does not disclose the digital twin of the fracturing truck used for drilling.

[0030] The prior art (CN204440705U) discloses a fracturing vehicle operating table, which includes a control panel 1 and a box 2. The operating elements distributed on the control panel 1 include one or more groups. The control panel 1 includes an inclined control panel area 3, a horizontal control panel area 4 and a hand pad area 5. The control panel 1 is evenly distributed with pointer instruments, digital display modules, switches, knobs, and indicator lights. The beneficial effects of the utility model are: it can not only meet the requirements of theoretical teaching, but also provide practical hands-on simulation training operations, enhance the on-site sense of teaching and training, shorten the training cycle, improve the training effect, and reduce the training cost. On the operating table, acid fracturing process training, acid fracturing vehicle operation training, layered fracturing process training, ball fracturing training, current limiting method fracturing process training, acid fracturing instrument detection, balanced fracturing training, fracturing acidification skills assessment and other projects can be realized.

However, there is no direct connection between the fracturing truck and the digital twin in the prior art (CN204440705U). Therefore, the prior art (CN204440705U) does not disclose the digital twinning of the fracturing truck used for drilling.

[0032] In view of the above-mentioned defects of the prior art, the present invention constructs a digital twin mapping model through an entity, and the digital twin is connected to the device entity through the digital twin mapping model; the sensor is installed on the device entity, connected to the device through a data interface, and the digital twin mapping model is used to collect relevant data and parse the protocol, thereby realizing the virtual-real interaction of the device entity in the digital space.

[0046] Specifically, based on modeling and data-driven, the synthesis of the overall twin of the fracturing truck is formed, and the development of effects such as model rendering, two-dimensional charts and roaming is realized.

[0047] In one embodiment, a digital twin method for a fracturing truck at an underground operation site further includes: for the digital twin model of the fracturing truck, rapid replication of models of different models and manufacturers is achieved through system model replacement and different data access operations.
