The invention provides a kind of high-altitude operation vehicle security system, for ensureing high-altitude operation vehicle in interference of electromagnetic field environment
Under work safety, in a schematical embodiment, as shown in figure 1, the security system include electromagnetic detection part 3 and control
Part processed.Wherein, electromagnetic detection part 3 is located in the working bucket 2 of high-altitude operation vehicle, can together be moved with working bucket 2, with
The electromagnetic field intensity of the present position of working bucket 2 is detected in real time.Working bucket 2 is located at one end of folding arm 1 by linking arm, operation
Carry out work high above the ground on the platform that person can stand in working bucket 2, linking arm also can as working bucket 2 a part, thus electromagnetism
Detection part 3 can be located at the position being easily installed on the side wall of the body of working bucket 2 or railing, or set and all exist on the connecting arm
Within protection scope of the present invention.Preferably, electromagnetic detection part 3 uses existing electromagnetic detection instrument.
Control unit is used for the detected value for receiving electromagnetic detection part 3, and judges current electric in the uphill process of working bucket 2
Magnetic field intensity exceed preset security value when, correspondingly adjust working bucket 2 running status, running status include the speed of service and/
Or traffic direction, traffic direction relates generally to working bucket 2 and lifts.Preset security value is obtained by testing, when the electromagnetism detected
When field intensity exceedes preset security value, illustrate that current electromagnetic field intensity may interfere with the operation of working bucket 2, and to work high above the ground
The safety of car produces influence, thus, when electromagnetic field intensity is detected more than preset security value, it is necessary to according to control unit
In default control strategy adjust the running status of working bucket 2.
Preferably, electromagnetic detection part 3 is located at the anterior position in working bucket 2, closer to radiation source, the letter received
It is number also stronger, and compromise can be played a part of, it can real-time and accurately detect the electromagnetic field intensity of the present position of working bucket 2
Degree, and the electromagnetic field intensity for maximizing closely detection radiation source radiation can be realized.Under such a installation site, electromagnetic detection
Part 3 is easy to the platform movement in working bucket 2, the especially strong place of some high-altitude electromagnetic field radiations, closer to spoke
Source is penetrated, the electromagnetic field being subject to is stronger, consequently only that being put on as the rise of working bucket 2 can just be detected on high-altitude operation vehicle
Most strong electromagnetic field signal.
Further, control unit includes magnetic field intensity judge module and speed adjusting module, speed adjusting module and magnetic

If continuing to lift up working bucket 2 may cause electromagnetic compatibility failure occur, thus working bucket 2 can be made to stop at present level, to protect
Demonstrate,prove the security of aerial work platform.Preferably, the 3rd ratio interval for (95%, 100%].
The specific embodiment can make working bucket 2 according to current electromagnetic field intensity and the degree of closeness of limiting safe threshold value
Run according to different speed stages, such a mode according to different operating modes setting corresponding speed adjustable strategies can be protected simultaneously
Hinder the security and operational efficiency of working bucket 2.Moreover, during working bucket 2 rises, electromagnetic field intensity gradually increases, control
The rate of climb of working bucket 2 processed is successively decreased by gear can make the steadily deceleration of working bucket 2, it is not easy to which generation is rocked, and ensures operation people
The safety of member, it is to avoid bring Psychological phobia to operating personnel.
Further, security system of the invention also includes warning piece, and such as audible-visual annunciator, warning piece is used for
Current electromagnetic field intensity is under the interval operating mode of the 3rd ratio, and speed adjusting module makes working bucket 2 be sent out while stopping rising
Go out alarm signal and carry out safety instruction, the information that working bucket 2 runs into strong-electromagnetic field in uphill process is conveyed into behaviour in time
Make personnel, operating personnel can supplementary security system change the running status of working bucket 2, especially broken down in security system
In the case of can ensure the security of high-altitude operation vehicle.
Further, control unit also includes rising locking module, rises locking module and is electrically connected with speed adjusting module,
For after speed adjusting module making working bucket 2 stop rising, the vertical motion mechanism of working bucket 2 being locked, work is imposed restrictions on
Make bucket 2 and the action continued to lift up occur, prevent maloperation.When electromagnetic field intensity reaches the critical value upper limit, rise locking
Vertical motion of the module to working bucket 2 carries out positive lock, to prevent the generation of maloperation, it is ensured that high-altitude operation vehicle is in electromagnetism ring
The safety of the construction operation in the severe place in border.
Present level position can be rested on after working bucket 2 stops rising to work on, or speed adjusting module also can
Enough control working buckets 2 decline, with timely away from the stronger region of electromagnetic interference.
During working bucket 2 declines, it is gradually distance from electromagnetic interference source and is in comparatively safe working environment.Control
Part also includes latch-release module, during declining working bucket 2 in speed adjusting module, judges in magnetic field intensity
When module judges that current electromagnetic field intensity is interval less than the 3rd ratio, such as less than 95%, release and rise locking module to work
Make the locking of 2 vertical motion mechanisms of bucket.After latch-release, speed adjusting module can control on demand working bucket 2 rise again.
Meanwhile, latch-release module can also make warning piece stop sending alarm signal.
Secondly, present invention also offers a kind of high-altitude operation vehicle, including the high-altitude operation vehicle safety described in above-described embodiment
System.Such a high-altitude operation vehicle carries out security monitoring for electromagnetic field, by being monitored to the electromagnetic field in working environment,
Electromagnetic field intensity around working bucket 2 changes the running status of working bucket 2 in time when larger, it is possible to increase high-altitude operation vehicle is pacified
Full construction, anti-locking system breaks down, and ensures the safety of operating personnel constructed in working bucket.
Finally, present invention also offers a kind of security control based on high-altitude operation vehicle security system described in above-described embodiment
