Data acquisition device of port gantry crane

Abstract

The utility model provides a data acquisition device of a port gantry crane, which comprises a main controller, an operation signal acquisition module, a sensor module, I / O (Input / Output) equipment and a crane power supply module. The utility model has the advantages that: when a worker swipes a card, the IC card needs to be put in from the upper part of the constraint sleeve, the information of the IC card is read through the information card reading module, and then the IC card falls to the position of the electricity-taking card reading module for electricity-taking operation. And the crane can be started to work after the steps are completed. After the work is completed, due to the arrangement of the clamping plate, the worker needs to lift the IC upwards and then pull out the IC towards the side face when taking the card, and the IC card is in contact with the staff information card reading module in the process, so that the staff information card is read again. Even if the previous staff forgets to take out the card, since the IC card is retained in the clamping plate, the latter staff can take out the card in order to input own information during working, so that the problem of information disorder caused by missing card swiping can be avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of data acquisition, in particular to a data acquisition device for a port portal crane. Background Art

[0002] Port gantry cranes are the most commonly used loading and unloading machinery in bulk cargo terminals because they can flexibly replace the operating spreader, change the operating berth, and have good mobility. In order to record the working conditions of the gantry crane, a data acquisition device needs to be set up to collect the working data.

[0003] An existing port gantry crane operation recording device adopts contactless IC card storage technology. It is not only easy to carry for users, but also the work records of the entire shift process cannot be changed at will, ensuring the authenticity and reliability of the data; the intelligent power isolation transmitter and main controller are adopted, so that the device also has the function of recording power consumption, which is convenient for the verification and assessment of energy consumption indicators and the recording of the work conditions of each driver. However, the device records the information of the on-duty driver through the IC card, and corresponds the operation record after swiping the card to the shift information. When the driver gets off the machine, he needs to swipe the card to download the data and then take away the IC card. In this process, it is easy for the driver to forget to download the data, which causes certain inconveniences for data collection. For this reason, a data collection device for a port gantry crane is proposed for improvement. Utility Model Content

[0012] The above technical solution is adopted: a piece of iron sheet of a certain length is welded at a certain angle at an unobstructed place below the circular base platform, so that the infrared sensor can sense and generate a signal when passing through the iron sheet during the rotation process, thereby obtaining the rotation angle signal. The touch screen in the I / O device has the functions of displaying and inputting information, and the keyboard is used to input information. The employee information card reader module reads the employee identity information, and the power card reader module uses the line connecting the crane power module and the crane to enable the crane power module to power the crane.

[0014] Preferably, any of the above schemes has a height of the restraint sleeve that is greater than a height of the employee information card reader module, and an upper end of the power card reader module is located inside the restraint sleeve.

[0015] The above technical solution is adopted: the employee information card reader module and the power card reader module are set on the same backplane, which is convenient for the staff to perform two card reading operations at one time. A restraint sleeve is set on the upper part of the backplane so that the restraint sleeve isolates the employee information card reader module from the outside. When swiping the card, the staff needs to put the IC card from the upper part of the restraint sleeve, and the IC card passes through the information card reader module to read the employee information.
