Description
Technical field
The present invention relates to detection techniques, and in particular to one kind is used for amusement facility over-speed protection function detection method.
Background technique
With the gradually development of market economy, the demand of masses' amusement and recreation becomes increasingly conspicuous.Amusement facility, which is used as, meets this
The effective carrier of kind demand, largely intensively occurs, but also expose some problems at the same time in China city.In recent years
Come, in qualification data, security protection, electrical and control, propulsion machine transmission, installation and connection, multiplies the inspection of people's facility operation
Look into etc. has had been found that and either large or small has not met situation.Due to China's amusement facility be grow up within nearly 30 years it is novel
Industry is started late, and the experience for not having accumulating and enriching also is designed and manufactured, and technical level is limited, the manufacture of equipment, installation, inspection,
Maintenance lacks unified standard, thus brings problems；The country's ten thousand failures of large-scale recreation facility send out rate complete and occupy generation at present
Boundary forefront.
The type of amusement facility is more, and development is also maked rapid progress, and has the quantity of nearly 1000 (sets) continuous every year
Increase, at the same time, also slowly development, the inspection or testing equipment of all kinds of amusement facilities are gradually put into for the inspection detection of amusement facility
It uses.But detection department as things go, is examined, inspection technology and equipment to be made to closely follow the production development of amusement facility
Level is relatively difficult.
The amusement facility for class of partially touring (refers to that multiplying people part surrounds recreation as trunnion axis movement and bulk motion form class
Machine), such as sea rover since transmission system uses the reason of direct current generator, it is possible to produce the danger of hypervelocity does not go out also at present
The method now detected specifically for the overspeed protection of amusement facility.

The beneficial effects of the present invention are:
Amusement facility over-speed protection function detection method of the invention inputs the parameter of electric machine by terminal, according to above-mentioned defeated
Enter the parameter of electric machine, the threshold speed (i.e. hypervelocity threshold value) for slowly driving amusement facility motor to set to its own using frequency converter；
When amusement facility speed be more than its own setting threshold value, when overspeed protection switch is triggered, monitors and record amusement facility
Overspeed protection switch action signal, itself frequency converter receive overspeed protection switch movement after issue alarm signal, travel
The state parameter of facility motor and braking response time；Whether acted according to amusement facility overspeed switch, at this time the revolving speed of motor,
The parameters such as braking response time judge the validity of over-speed protection function；Quantitative detection, tool are carried out to overspeed protection movement speed
There are high accuracy, high-efficient, high degree of automation, adaptable, low cost, only need to set control parameter and will count
At the frequency converter of acquisition module access amusement facility and overspeed protection switch contact, it can be realized to amusement facility overspeed protection
The high-precision fast quantification of braking response time measures；Not only vertical rotary class amusement facility can have been measured, but also level can be measured
Rotate class amusement facility.
Furthermore the present invention solves testing staff and is only capable of by checking whether design operation instructions and equipment are equipped with hypervelocity
Protective device can not simulate the difficulty of overspeed unsafe condition, so as to judge the validity of its overspeed protective device, gram
The defect that controller is highly specialized, and the personnel of profession is needed to be configured and debug has been taken, the difficulty for examining detection is reduced
Degree eliminates the security risk of survey crew during traditional measurement, and is not necessarily to the support of special hardware, the time required to measurement
It is short, serious influence will not be caused on the operation at scene.
