Abstract

The invention relates to an intelligent driver which is composed of an input/output module, a bus communication module, an embedded controller (ECU) and an executing module. The ECU is responsible for program operation; the input/output module inputs and outputs the switching value and the analog quantity under the control of the ECU; the bus communication module enables the driver to conduct data interaction with the other devices on a bus of the system; the intelligent driver is used for an often-closed type electro-hydraulic or electromagnetic brake; the executing module is classified into a transducer or a direct current voltage regulator according to objects. By frequency conversion, electronic voltage-regulation and computer technologies, the traditional often-closed electro-hydraulic or electromagnetic brake is intelligently transformed, so that the traditional brake with an opening state and a closing state only can become the intelligent brake with controllable brake force and brake time, so that 1) the brake process is stable, the brake impact is mitigated, a transmission chain is protected and the service life of every mechanism is prolonged; 2) the dynamic energy can be effectively dissipated at the brake, so that the brake has the damping function; 3) the brake is beneficial to saving energy and reducing temperature, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the industrial field, and in particular relates to an intelligent driver. Background technique [0002] Normally closed electro-hydraulic or electromagnetic brakes are commonly used equipment in the industrial field. They are usually used for the braking of crane trolleys, carts, hoisting and luffing devices, the braking of wind power equipment, and the prevention of sagging of anchor chains when ships break down. Its function is to brake the moving parts according to the driver's command. Traditional normally closed brakes only have opening and closing functions, without a controllable intermediate state. When the brake is braking, there is a phenomenon of directly locking the brake disc, which will generate a huge impact force, and also cause the local part of the brake to heat up rapidly and be damaged. In some applications, such as emergency stop conditions, it may even cause damage to weak parts in the transmission chain...
