The invention has the beneficial effects that: the PLC controller ensures whether the tower crane is started to normally run or not by combining the opening and closing of the contactor according to the identity recognition signal detected in real time, ensures the safe operation of the tower crane, and effectively prevents common personnel who do not have corresponding professional qualification from operating the tower crane equipment.
Description
Technical Field
The invention relates to a safety control method of a tower crane identity recognition system, and belongs to the technical field of tower cranes.
Background
ID card punching records are commonly adopted in the existing tower crane industry to control the operation process of tower crane starting operation, so that the operation of non-professional personnel on the tower crane in the operation process of the tower crane cannot be limited. Therefore, in the industry, some manufacturers install cameras in the drivers' cabs to monitor and obtain monitoring pictures, but the omission in the monitoring process cannot be avoided, and thus the operation of non-professionals on the tower crane cannot be completely prevented.
In the prior art, the operation of the tower department is supervised and managed by adopting a card punching mode, and the tower department can operate by punching the card. Therefore, several technical disadvantages arise: the card punching mode can only be used for recording attendance of the tower crane, the real-time operation of the tower crane cannot be monitored, and the operation of non-professional personnel on the tower crane cannot be avoided. By adopting a card punching mode, the ID card does not have binding property, can be punched by other people, and also has randomness for the attendance record of the toast.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides the safety control method of the tower crane identity recognition system, the identity of a tower crane driver is determined through the tower crane identity recognition system, so that common personnel without corresponding occupational qualification are effectively prevented from operating tower crane equipment, the standardization of tower crane operation is ensured, and safety accidents of the tower crane caused by the operation of irrelevant personnel are avoided.
The invention is realized by the following technical scheme: a safety control method of a tower crane identity recognition system is characterized in that: the tower crane identity recognition system comprises identity recognition equipment, a mobile phone client, a CAN bus and a PLC controller, wherein the identity recognition equipment, the PLC controller and the mobile phone client are integrated through the CAN bus, and the PLC controller respectively controls the lifting, rotating and amplitude variation of the tower crane;
when the tower crane is started, identity information of a tower crane driver is input through identity recognition equipment;
the identity recognition device sends the identity information of the tower crane driver to the mobile phone client of the ground commander through the GPS, and the ground commander transmits the information to the Internet of things big data platform after receiving and confirming the identity information;
after the ground commander receives and confirms the identity information of the tower crane driver, the Internet of things big data platform carries out corresponding model relation calculation by comparing the registered image template with the feature point set of the image acquired by the identity recognition equipment to obtain a similarity score, the similarity score is compared with a threshold value set in a background, if the similarity score is within a threshold value allowable range, a pass signal is output, otherwise, a forbid signal is output, and the output information is fed back and transmitted to the PLC through the CAN bus;
according to the signal fed back by the Internet of things big data platform, if the signal is a 'pass' signal, the signal input end contactor corresponding to the PLC is closed, and the lifting, rotating and amplitude-changing actions of the tower crane are started normally; if the tower crane is illegally intruded, the PLC starting signal input end contactor cannot be closed, and meanwhile, an alarm prompt appears, the tower crane cannot work, and the working safety of the tower crane is detected in real time. The PLC is connected to the Internet of things big data platform through a CAN bus.
And the mobile phone client is connected with the video monitoring equipment at the front end of the identity recognition system through a GPS.
The identity recognition equipment is a face recognition camera.
The invention has the beneficial effects that: the PLC controller ensures whether the tower crane is started to normally run or not by combining the opening and closing of the contactor according to the identity recognition signal detected in real time, ensures the safe operation of the tower crane, and effectively prevents common personnel who do not have corresponding professional qualification from operating the tower crane equipment.
