Management problems exist for any social activity, and the complexity of the social activity determines the generality and adaptability of the management technology. With the rapid development of the internet technology, the management technology is also greatly improved.
Along with the improvement of the mechanization degree of the construction site, the use of the construction elevator of the construction site is more and more popular. However, because the construction site management is extensive, and the general culture level of workers in the construction site is not high, the safety awareness is not strong, so that the safety accidents in the construction site are endless, and serious economic losses are caused to enterprises and families.
In addition, construction elevators on a plurality of construction sites are leased, the maintenance conditions of the elevators are poor, and various potential safety hazards, such as broken falling protectors, fault limiters and the like, exist in the installation of some elevators. These problems are difficult to detect at ordinary times, but once they are expressed, they are often a big accident of machine destruction and human death.
Moreover, construction periods of construction sites are often tense, and in order to accelerate project progress, the limitation on the use of the elevator can be released by part of construction units, so that the phenomena of excessive personnel, overload and non-professional operation of the elevator can be easily caused.
The safety of the building is threatened, and meanwhile, the personal safety of other people on the construction site is also harmed.
It can be known that the safety and intelligence of construction elevators have become bottlenecks that restrict the safe construction of construction sites.
At present, the problems existing in the use of the construction elevator are summarized according to the actual use condition of the construction elevator on the construction site as follows:
1. the construction elevator is not strong in use management force, and violation phenomena such as overload, mixed loading of people and goods and the like occur.
2. The construction elevator is mostly leased equipment, and the operating mode is relatively poor, and a lot of elevator maintenance is not timely enough, and partial mechanical part and electronic parts damage seriously, have great potential safety hazard.
3. The intelligent degree of the construction elevator is not high, the self-checking capability of the equipment is poor, and in addition, the elevator is not checked and maintained by professional personnel on a construction site, so that the hidden trouble of the elevator in the use process cannot be discovered and solved in time.
Therefore, the problems can be effectively solved only by establishing a safety intelligent control system of the construction hoist and improving the intelligent level of the construction hoist.

Wherein the check algorithm may use CRC16 check algorithm to ensure the correctness of the data.
Specifically, in order to ensure that the elevator is operated by a specially-assigned person, the control system identifies and determines the identity of the current driver in a plurality of ways, including: a driver card identification system, a fingerprint identification system, a face scanning identification system and the like. The driver card identification system comprises a driver card identification device and a driver card, wherein the driver card stores the identity card information of a driver, the driver inserts the card into the driver card identification device before the driver starts the elevator, and the driver card identification device reads the identity card information stored in the driver card and compares the identity card information with the driver identity information stored in the control system to determine that the driver does not have the authority to operate the elevator; in addition, the driver can also scan the fingerprint through a fingerprint recognition system or recognize the face information through a face recognition device to judge whether the driver has the driving authority. If no driving authority is detected, the control system cuts off the power supply of the elevator through the execution system. The execution system comprises one or more of a relay, an electric valve and an electronic switch, and the relay is generally used.

When the control system detects that the inclination angle of the standard knot exceeds the set range, the control system immediately and comprehensively checks the operation of the elevator, and after the reasons of error of the measurement data of the inclination angle measurement module (small change of repeated measurement values), inappropriate jerking and jerking operation of a driver (small change of measurement values at intervals) and the like are sequentially eliminated, the system judges that the structure of the standard knot of the elevator has a problem. On one hand, the control system can cut off the power supply of the elevator through a relay of the disconnection execution system, and meanwhile, the control system alarms, reminds of maintenance through a touch display screen and an alarm lamp of the information acquisition display system.
