Condition monitoring and fault diagnostics of
amusement device - Part 1. General requirements
1 Scope
This Part of GB/T 36668 specifies the general requirements and procedures for
condition monitoring and fault diagnostics of amusement device.
This Part applies to condition monitoring and fault diagnostics of newly-
manufactured and in-use amusement device.

3 Terms and definitions
The terms and definitions defined in GB/T 6444, GB/T 20306, GB/T 20737, and
GB/T 20921, and the following are applicable to this document.
3.1 Health management of large scale amusement device
Through risk analysis, the health risk factors of large scale amusement device
are determined; the items and indicators of health management are established.
Through various inspection, testing, and monitoring methods, the health
information of the device is obtained; its health condition is diagnosed and
evaluated; and the unhealth condition found is maintained, repaired, or modified,
etc., to eliminate device fault, restore device health, and improve device design.
Note. The health management of large scale amusement device is a process of
comprehensively managing the health risk factors of large scale amusement device
with the aim of preventing and controlling accident occurrence and development,
reducing operating cost, and achieving safe, reliable operation and economic
coordination and unification of large scale amusement device.
3.2 Baseline
One or a set of descriptors which provide a benchmark for the normal condition
of each system of amusement device.
Note. The baseline is determined in the condition of steady operation of amusement device.
3.3 Baseline data
The measured or observed data or data set when the amusement device is in
an acceptable and stable operating condition.
4 Overview of condition monitoring and fault
diagnostics
4.1 Main content
4.1.1 Condition monitoring is to understand and master the operating condition
of amusement device through certain methods; and to use various methods of
inspection, testing, monitoring, analysis, and judgement to evaluate whether
the current operating condition of amusement device is normal; to make timely
alarms for abnormal conditions; and to provide information and data for further
fault diagnostics, performance evaluation, etc..
4.1.2 Fault diagnostics is, based on the information obtained by condition
monitoring, combined with the working principle, structural characteristics,
operating condition parameters, implementation status of amusement device,
to analyze and predict the faults which may occur in the future, and to analyze
and judge the faults which have occurred or are occurring, so as to determine
the nature, type, degree, position, and trend of the fault.
4.1.3 The purpose of implementing condition monitoring and fault diagnostics
is to provide a basis for scientific development of maintenance and repair plans
for amusement device, to timely warn potential faults and reduce the possibility
of failure, and to prevent accidents.
4.3 Use principles
4.3.1 It shall, according to the material, structure, manufacturing method, use
environment, use conditions, and damage mode of the device to be tested,
predict the types, shapes, positions, and directions of defects which may occur,
and select appropriate monitoring methods.
4.3.2 Acoustic emission method shall be selected for condition monitoring of
low-speed rotating installations/components of amusement device. There are
temperature changes caused by damage or fault in the mechanical and
electrical parts of in-use and in-manufacturing amusement device, infrared
thermography method is preferred. The vibration condition monitoring method
can be adopted for high speed rotating installations/components or structures.
The stress-strain method can be used for the condition monitoring of large
frame structures or strutting pieces.
4.3.3 When two or more monitoring methods are used to monitor the same
position of amusement device, the monitoring results shall be assessed
according to their respective methods.
4.3.4 When using the same monitoring method to monitor according to different
testing processes, if the severity of defect is diagnosed inconsistent, the
assessment result with greater risk degree shall prevail.
4.3.5 The instruments, consumables, etc. used shall comply with the
requirements of relevant condition monitoring method standards.
5 Implementation organization
5.1 The organization which conducts condition monitoring and fault diagnostics
of amusement device (hereinafter known as the implementation organization
for short) shall have professional technical personnel equipped with the
experience of working with the corresponding monitoring methods; and shall
formulate management methods for the monitoring personnel.
5.2 The implementation organization shall have special instruments and
equipment for carrying out the corresponding monitoring methods; and shall
formulate corresponding management methods for the instruments and
equipment.
5.3 The implementation organization shall, in accordance with the provisions of
this Part and the corresponding monitoring method standards, develop the
process specification.
d) Intermediate checks. When necessary, the monitoring equipment and
main apparatus shall, during the verification, calibration, or check cycle,
be subjected to intermediate checks. The items, cycle, and performance...
