s2: after receiving the position of the platform to be checked and accepted and a checking and accepting instruction, the selecting and checking and accepting module sends a position obtaining instruction and a checking and accepting request instruction to a mobile phone terminal of a registered person;
s3: when the mobile phone terminal of the registrant receives the position acquisition instruction and the acceptance request instruction, and sends an agreement instruction and the current real-time position to the selection acceptance module; the selection acceptance module marks the registered person as a primary selection person, and calculates the time difference between the time of receiving the agreement instruction and the time of sending the acceptance instruction to obtain the response time T1 of the primary selection person;
s4: calculating the distance difference between the current real-time position of the primary selection personnel and the position of the platform to be checked to obtain a checking and accepting distance and marking the checking and accepting distance as G1;
s5: obtaining acceptance values of the primary election personnel and marking as Y1; normalizing the response time length, the acceptance interval and the acceptance value of the primary selection personnel and taking the numerical values;
s6: obtaining a quality test value QS of the primary candidate by using a formula QS (1/G1). times.b 1+ muxx [ (1/T1). times.b 2+ Y1 xb 3] -1.398; wherein b1, b2 and b3 are all preset proportionality coefficients, mu is a correction factor, and the value is 0.98145;
s7: marking the primary selected person with the maximum optimal value as an acceptance person; the method comprises the steps that a selection acceptance module sends a position of a platform to be accepted and an acceptance instruction to a mobile phone terminal of an acceptance person, and the time of sending the acceptance instruction is marked as a notification time;
s8: after receiving the position of the platform to be checked and the checking instruction, the checking personnel arrives at the position of the platform to be checked and sends a starting instruction and a current real-time position to the selection checking module through the mobile phone terminal, the selection checking module receives the starting instruction and the current real-time position and then carries out verification, when the position of the platform to be checked and accepted at the current real-time position is coincident, the selection checking module marks the moment of receiving the starting instruction as an execution moment, and meanwhile, the selection checking module generates the execution instruction and sends the execution instruction to the mobile phone terminal of the checking personnel;
s8: after receiving the execution command, the acceptance staff inspects the platform to be accepted, the inspection comprises the fastening degree of the bolt, cracks on the surface of the welding seam, welding beading, burning-through, arc pits, air holes on the surface of the welding seam, slag inclusion, the arc pits, cracks and electric arc scratch inspection, and the inspection result is sent to the server, and meanwhile, the total number of times of the inspection of the acceptance staff is increased once.
3. The practical tower crane wall-attached operation platform construction method according to claim 2, wherein a registration login unit and an information analysis unit are further included in the server; the registration login unit is used for the inspector submitting registration information through the mobile phone terminal to register and sending the registration information which is successfully registered to the server for storage, wherein the registration information comprises the name, age, identification number and time of enrollment of the inspector, and the server marks the successfully registered registrant as a registrant; the information analysis unit is used for analyzing the registration information of the registrant, and the specific analysis steps are as follows:
SS 1: calculating the time difference between the enrollment time of the registrant and the current system time to obtain the enrollment duration of the registrant, and marking the enrollment duration as D1; the age and total number of exams of the registered persons are marked as D2 and D3, respectively;
SS 2: normalizing the enrollment duration, age and total number of examinations of the registered person, and taking the value thereof
Obtaining an acceptance value Y1 of the registered personnel; wherein b4, b5 and b6 are all preset proportionality coefficients;
SS 3: and the information analysis unit sends the acceptance value of the registered person to the server for storage.
4. The construction method of the practical tower crane wall-attached operating platform according to claim 1, wherein a plurality of angle steels are further installed on the operating platform, and a layer of fence pieces are welded on the angle steels; the supporting legs comprise square steel, flat iron and bolts.
