It is set as 1 point；2,4 steps are set as 2 points；7 steps are set as 10 points；According to step type, program, which passes through, to be checked or operates to divide
Section, analysis obtains step logical relation 1 → (2 → 3,4 → 5) → 6 → 7 → 8, while program can also be sentenced according to scheduling rule etc.
Disconnected 2 and 4 whether be 7 preparation operating procedure, so far, model answer content automatically generates；
2) computer depth assessment designs：
(1) computer depth assessment flow：
According to system condition, True-False purpose primary condition, then task analysis is carried out, determines operating process；
(2) computer depth assessment design is carried out according to operating procedure logical relation：
1. it is the design to step logical relation and parsing that machine, which assesses a key job, this method is walked with arrow " → " mark
Rapid sequencing, with the coordination of bracket " () " identification of steps, " 1 → (2 → 3,4 → 5) " indicate ability after the completion of 1 step
2 → 5 steps are carried out, could carry out 3 steps after the completion of 2 steps, 4 steps could carry out 5 steps after the completion, and 2 and 4 and 5 without sequence requirement, and 3
Walking also is；
2. since power station emulates the uniqueness that automatic journal function ensure that the output of operating procedure content, user can be used in judge
The character string of operation content is compared to judge with model answer, in order to improve judge speed, using character string hash means
Character string is switched into long type numbers, character string comparison flow is converted to number relatively, substantially increases judgement speed；
3. judgement is using deduction of points system, by comparing, position of the localization criteria answer step in user's operation content first, according to
Location information, you can the defect information for obtaining user's operation includes scarce step, multistep, sequence is anti-, is remedied, while in operation
Program automatically record user violate five anti-criterion behavior information include prevent accidentally point or close breaker, prevent on-load point or close every
Pass is left, band cable address or splice grafting ground wire and earthing switch is prevented, prevents line and earthing switch with ground from closing breaker or keeping apart
It closes, prevent mistakenly entering charged chamber, error span from operating row information, according to these information, program deducts the percentage of total score, including
100%, i.e., it must be 0 point；
4. programmed decision pattern can be divided into high-precision and high speed, high precision mode comments each step information of user
Estimate, high speed pattern can stop judgement when deduction of points reaches the 100% of total score；
5. evaluation process carries out calculating realization using after infix expression model answer is switched to postfix expression；
3) system makes an inspection tour depth assessment content：
1. making an inspection tour device class is divided into position class equipment and meter class equipment, position class equipment includes：Breaker, disconnecting switch,
Change-over switch, pressing plate；Meter class equipment includes：Water gage, pressure gauge, oil level gauge；
2. making an inspection tour deduction of points principle：Equipment-patrolling redundant term not impact evaluation achievement, missing, which is maked an inspection tour, deducts corresponding score value；
4) system operation assesses content：
1. operation equipment is divided into electrical equipment and mechanical equipment, difference lies in the different modes that operation is latching logic for the two；
The principle 2. equipment operation is deducted points：Lacuna deducts corresponding score value, and redundant term is according to extra type and influences to deduct points, and does not answer
Some equipment operations cause improper equipment to be stopped transport, cause accident, is random to equipment progress multi-pass operation；
5) it repeats operation equipment operation and assesses content：
Judge the state of system before result is submitted in examination, and judges whether consistent with required by task end-state.
