Embodiment Construction

[0017] In order to further describe the technical features and effects of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as Figure 1-2 As shown, the system used in the present invention includes a start button, a power supply logic circuit, a vehicle controller, a vehicle instrument, a CAN bus and an output control, wherein the start button is a self-resetting button.

[0019] When in use, the start-stop process of construction machinery is mainly as follows:

[0020] First, when the control system is powered on, when the start button is pressed for the first time, the power supply controls the coil of relay 1 through the start button and the normally closed outlet of relay 2, so that the normally open contact of relay 1 is connected, and the vehicle controller The power supply port is powered, the vehicle controller works, the vehicle controller power supply s...

Abstract

The invention discloses a keyless start control method for engineering machinery. The method comprises the steps that a control system is powered on; system permission is verified; and system starting-stopping controlling is performed. According to the method, a problem of starting and stopping of the engineering machinery vehicle in a keyless state can be solved; and the personnel authority management can be completed under the condition that the vehicle cost is not increased. Moreover, in consideration of the working characteristic that the engineering vehicle often stops working for a longtime, a power supply logic control loop ensures that the vehicle controller is not electrified in a standby state; meanwhile, keyless starting is realized, so that a problem of power shortage of the storage battery caused by standby electrification of the controller in a long-time stop state is solved.

Description

technical field [0001] The invention relates to the technical field of construction machinery control, in particular to a keyless start control method for construction machinery. Background technique [0002] The construction of construction machinery usually involves multiple vehicles and multiple machines working together. The vehicles may belong to different units and individuals, or may belong to the same unit and individual. One machine with one key, and one key with multiple machines will face key management, key imitation and Loss, personnel rights management and other issues. Especially in large-scale construction sites, the external environment such as personnel and sites is complex, which brings difficulties to vehicle management key and authority management. Contents of the invention [0003] In view of the above problems, the present invention provides a keyless start control method of construction machinery, which can realize keyless start management of const...
