Problems solved by technology
[0002] The existing factory workshops rely on manual labor to transport goods by car. Operators in the car are allowed to look down and observe the condition of the goods on the ground, especially when lifting when the sight is unclear and the weight of the goods is unclear, production safety accidents are prone to occur.
During the operation of the vehicle, it also ignores the operators below, which is very likely to cause safety hazards

Embodiment Construction
[0026] refer to Figure 1-2 As shown, the present invention proposes a driving control system, including a controller 7, and also includes an ultrasonic ranging sensor connected to the controller 7 and positioned on the hook 31 for hoisting, for detecting the vertical distance between the hook 31 and the ground tag 6. distance;
[0027] PSD alignment sensor is used to detect whether the vertical projection on the ground of the hook 31 coincides with the ground label 6;
[0028] A weighing sensor is used to measure the weight of the goods 4 on the hook 31;
[0029] An infrared pyroelectric sensor is used to detect whether there is a pedestrian under the hook 31;
[0030] The controller 7 is also connected to the drive of the vertical motor 22 and the drive of the horizontal motor 21 , and the vertical motor 22 and the horizontal motor 21 move relative to the truss 1 .
[0031] The system also includes a wireless transmission module and an alarm unit, the wireless transmissio...

The invention provides a travelling crane control system and method. The system comprises a controller and further comprises an ultrasonic distance measuring sensor, a PSD collimation sensor, a weighing sensor and an infrared pyroelectric sensor, wherein the ultrasonic distance measuring sensor is connected to the controller, is located on a hook for hoisting and is used for detecting the vertical distance between the hook and a ground label, the PSD collimation sensor is used for detecting whether the vertical projection of the hook on the ground coincides with the ground label or not, the weighing sensor is used for measuring the weight of goods on the hook, and the infrared pyroelectric sensor is used for detecting whether a pedestrian is below the hook or not. The travelling crane control system and method have the advantages that the hood can be automatically connected to the goods in a butt joint mode, the weight of the goods can be automatically limited, it is guaranteed that the goods can be safely transported within the weight range of the goods, in the transportation process, when a travelling crane encounters field workers, an alarm signal is sent out, and the running safety of the travelling crane is guaranteed; and the design structure is simple, the purpose of safe production is achieved, and participation of the workers is reduced.
Description
technical field [0001] The invention relates to the technical field of cranes, in particular to a driving control system and method. Background technique [0002] Existing factory workshops rely on manual labor to move goods by car. Operators in the car are allowed to look down and observe the goods on the ground, especially when lifting when the sight is unclear and the weight of the goods is unclear, production safety accidents are prone to occur. In the process of driving and running, the operators below are also ignored, which is very likely to cause safety hazards. How to ensure that the hook is accurately docked with the goods, limit the lifting weight, warn the on-site operators, and ensure safe production are problems that need to be solved urgently. Contents of the invention [0003] In view of the deficiencies in the background technology, for this reason, the present invention proposes a driving control system and method, the specific scheme is as follows: [...
