It is shown in reference picture 1, Fig. 2, a kind of electric analog tutoring system based on VR, including display component, Haptics components and
Control assembly；
The display component is for showing virtual training on electric power scene；
Specifically, the display component includes the VR helmet, described convenient for showing virtual training on electric power scene to trainer
Training on electric power scene includes that cable production training scene, equipment-patrolling scene and maintenance of equipment scene are also wrapped in a particular application
Other similar training scenes are included, for example, earthing test training, Insulation test training etc., include and electricity in training on electric power scene
The corresponding demonstration picture of power training scene demonstrates difference by the operation of Haptics components selectivity according to the wish of trainer
Demonstration picture, trainer by viewing study, promote its familiarity accordingly trained.
The Haptics components carry out operating generated operand for obtaining trainer according to the training on electric power scene
According to；
Specifically, the Haptics components include VR gloves, and the VR gloves include glove bulk, the wrist of the glove bulk
Portion is equipped with sender unit, is equipped with heat release hole, the finger joint of each finger chamber of the glove bulk at each finger tip of glove bulk
Place is equipped with shaft, and the top at the finger joint of each finger chamber is equipped with inertial sensor, and the lower part at the finger joint of each finger chamber is equipped with
Data chip；It is worn in this way convenient for operator, there is better man-machine interaction experience, operation when meeting practical application is practised
It is used, it is formed conducive to the operating habit of trainer.
The control assembly is for receiving and processing the operation data to obtain control command, and by the control command
Externally send；
Specifically, it as shown in Fig. 2, the control assembly includes shell 1 and control panel 2, is installed on the first face of control panel 2
There is electronic component 22, control panel is equipped with the electronic circuit for being electrically connected electronic component 22, is in series on electronic circuit electronic
The coil 17 of valve, coil 17 are set on the coil fixing body 21 being fixedly connected with valve plate 15, when coil 17 occurs mobile,
Coil fixing body 21 also will drive valve plate 15 and move, and coil 17 is arranged in magnetic field, and magnetic field can be generated by U magnet,
Magnetic field moves the magnetic induction line to change the openings of sizes of electrically operated valve, in magnetic field for control valve core perpendicular to coil axial direction, electricity
The opening of movable valve is provided with the spring 23 connecting with valve plate 15, and spring 23 is set on sliding axle 14, sliding axle 14 also with
Valve plate 15 is fixedly connected, and the other end of spring 23 is against on the spring support 19 being fixedly mounted on cooling line 13, spring 23
For pushing valve plate 15 to close the opening of electrically operated valve, electrically operated valve is arranged on cooling line 13, the outlet of electrically operated valve
16 setting directions of mouth are so that being sprayed by the air-flow that opening sprays towards electronic component 22, cooling line 13 is located at control panel 2
Second face side, the second face are the reverse side in the first face, and cooling line 13 is sent out with cooling gas input device or cooling with gas
Generating apparatus connection.
Wherein the air inlet of cooling line 13 is had using by the way of shell external admission, being additionally provided with exhaust outlet 20 on shell 1
Body is got on very well, and uses air inlet device air inlet by cooling, by filter device 12, then has cooling fan 11 to be blown into cooling line 13
In.
When using gas caused by cooling gas or cooling gas generating unit from external world's introducing, pass through pipeline
It imported by the electronic component 22 of fever, it is lower, heated not by other electronic components 22 to can use temperature
Cooling cools down these electronic components 22 with gas, and cooling effect is more preferable, and cooling velocity faster, will be electric in favor of realizing
The temperature of subcomponent 22 maintains in lower level.Moreover, by the way that coil 17 is connected in series to circuit board to connect electronics member
In the route of part 22, when electronic component 22 more needs to radiate, and all thermal powers caused by it, electrical power is derived from, and
Electrical power is bigger, and electric current is also bigger, so coil 17 can produce bigger active force, band moving winding fixing body 21 and valve
Right side of the plate 15 into figure is mobile, to fight elastic force caused by spring 23.When bigger elastic force can be generated, elastic shape
Become bigger, so that the opening of electrically operated valve is bigger, the flow for the cooling gas that can pass through is also bigger, and cooling capacity is got over
By force.To realize the different cooling effects of electronic component 22 for different operating temperature, or for same electronic component 22,
Different cooling effects in different temperatures, to improve cooling gas input device or cooling gas generating unit exists
Working efficiency when identical quantity cooling gas is imported, cooling capacity is improved；Because control assembly is the core of whole system
The heart, at runtime, long operational time, its calorific value are big, are a big industry pain spots of VR system, for the stabilization for guaranteeing the system
Property, it is very necessary by cool down to it, and in the prior art, do not occur similar solution also.
The display component is also used to according to the control command, virtual training on electric power scene described in real-time update.
Specifically, after trainer completes single stepping, control assembly updates the virtual training on electric power according to its operation
Scene, for example, equipment 1 in scene is moved to B point from A point by operator, after completing this step operation, the virtual training on electric power field
Equipment 1, which will update, in scape arrives B point.
Further, in order to be more in line with actual working environment, its training quality, a kind of base are further increased
It further include tool assembly in the electric analog tutoring system of VR, the tool assembly is for providing various virtual electric power tools.
Here electric power tool includes but is not limited to wire stripper, cutting pliers, Crimping Pliers, test pencil, screwdriver and voltmeter etc., application
When, it can be chosen by VR gloves.
Further, it in order to allow trainer to have an objectively cognition to the operation of oneself, sees whether to reach corresponding
Standard, a kind of electric analog tutoring system based on VR, further includes test module, the test module is previously stored with
Testing standard, and operation data caused by each step of Haptics components is tested, and test result is stored, and leads to
The display component is crossed to be shown.
Specifically, for example, current scene be cable connector training, to trainer operation each step, for example, when wire stripping
Whether injure core, shielded layer whether destroy, cable accessory whether select it is suitable etc. be compared according to corresponding cable connector,
Test after completing, also carries out corresponding waterproof test, be powered the operation such as test and tensile test.When display component is shown,
The test result of each step can be shown in the side of virtual training on electric power scene, after several seconds can also being shown in scenic picture
It disappears, specific display form, herein with no restrictions.
It should be noted that the present embodiment has done some omissions to some prior arts, those skilled in the art should
Solution refers to the Dummy modeling mechanical assembly software of current mainstream, for example, France reaches for example, being equipped with three-dimensional modeling software in control assembly
The CATIA/DELMIA of Suo company exploitation is imported with virtual hand model for supporting three-dimensional environment needed for emulation wherein
