Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment provides an evaluation method for an energy pile bridge face deicing system based on a body, as shown in fig. 1, comprising the following steps:
step 101, setting basic data of an energy pile bridge face deicing system, wherein the basic data comprise: energy pile foundation heat exchange parameters, bridge deck heat exchange, pump type parameters and parameters;
specifically, in this embodiment, the energy pile foundation heat exchange parameters include: the total cost, the safety coefficient, the total vertical bearing capacity, the calculated heat flux, the actual heat flux, the heat flux with the heat pump, the total extracted heat, the total heating heat, the evaluation and other attributes;

pump type parameters, including: data attributes such as cost, quantity, energy efficiency ratio, power and the like;
bridge deck heat exchange tube parameters, including: length and monovalent attributes.
As shown in FIG. 9, when basic data is set and properties are added, some data such as electricity price and the like can be directly imported from a database, some data are needed to be manually added, and other data such as equipment cost and CO saving and discharging 2 The method is obtained by SWRL rule reasoning operation.
The corresponding entity case, i.e. the individal, is established according to engineering design requirements, and the instance established in the step is a concrete instance of the class and is not an abstract concept, and the same kind of the entity case has own position and hierarchy structure. The steps in setting up the instance are: (1) selecting a class in which an instance needs to be established; (2) creating an instance in the selected class; (3) adding attributes to the instance. When adding properties, some data can be directly imported from the database, and specific engineering data needs to be manually added. There are mainly five data types in the ontology regarding the data types: string, number, bootie, event-type. Since design cases will involve a large number of operations and a variety of data types, the data types may be selected according to requirements.
102, defining a plurality of classes corresponding to the ontology model and attributes corresponding to the classes according to the basic data, wherein the attributes comprise relationships and data properties among the classes;
specifically, as shown in FIG. 10, the attributes of a class typically include two classes, namely Object properties and Data properties. The relationship between classes is defined in Object properties, and if the type of the heat exchange tube of the bored pile is a single U type in this embodiment, the class of the cast-in-situ pile and the single U type may be connected by means of the has_heat_exchange_tube_type, which may be denoted as the cast-in-situ pile-has_heat_exchange_transfer_tube_type. Data properties indicate the Data properties of the class, such as the price, length, etc. of the heat exchange tube; if 120 bored piles with the pile length of 20 meters are indicated, number, length and other Data properties can be added into the category of the piling_pile. Typically defining classes and their hierarchical relationships is done across the nature of the defining class.
The creation class includes the following three methods.
1) The method from top to bottom comprises the following steps: the method starts from the most basic concept in the field, and refines and specializes basic terms and concepts, for example, a heat pump in a ground source heat pump system is a basic concept, can be used as an upper class, and can be provided with different classifications of ground source heat pumps, such as a gas source heat pump, a ground source heat pump, a water source heat pump and the like.
2) The method comprises the following steps: the method starts by defining the most specific classes (the bottom layer of the hierarchy) and then groups these classes into a more general concept. Specific classes such as tunnel lining, primary support, secondary support, etc. can be categorized as structural classes of tunnels.
3) The combination method comprises the following steps: the combinatorial development process is a combination of top-down and bottom-up methods, we first define the salient concepts, then appropriately generalize and specialize them, then we can link them with a mid-level concept, in an energy stake system, we first define the concept of energy stake, then it involves the ground source heat pump system and building structure, from which the classes of ground source heat pump system and building structure are re-established.
Step 103, an evaluation rule of the energy pile bridge face deicing system is prepared by adopting a semantic network rule, wherein the evaluation rule comprises the following steps: feasibility rules, cost calculation rules, heat extraction rules, heat flux calculation rules and pile foundation bearing capacity calculation rules of the deicing system;
in the embodiment, SWRL semantic network rules are adopted, and corresponding feasibility evaluation rules, cost calculation rules, heat extraction rules, heat flux calculation rules and pile foundation bearing capacity calculation rules of the energy pile bridge surface deicing system are formulated by defining classes and attributes of the classes. The SWRL rule language can be perfectly connected with the ontology, and can be written and operated in a prot g software environment, and most importantly, the SWRL rule can be transplanted and multiplexed along with the ontology model.
Typically, there are four atoms in the SWRL rule, respectively: a class atom; single attribute atoms; a data attribute atom; built-in atoms, atoms are connected by "? "used to represent a variable, such as (. A single attribute atom contains an OWL ontology of object attributes and two variables, each representing an individual in the ontology. If "haspin" then represents that the energy pile system contains pile foundations, it may be expressed in its entirety as haspin (. The data attribute atom is similar to the single attribute atom and also includes two variables, such as the length of the stub can then be expressed as (. The built-in atoms can support functions such as mathematical computation, such as addition, subtraction, multiplication and division, absolute value taking, square, power and other common computation functions.
After specific reasoning and calculation are carried out on the ontology model, SQWRL screening rules are required to be defined in order to effectively acquire useful information and screen data required by the ontology model according to different requirements. The SQWRL rule language is basically the same as SWRL rule and is a rule language based on semantic net, and the SQWRL rule language can be written and operated in a prot g software environment and can also be transplanted and multiplexed along with an ontology model.
