Embodiment Construction

[0021] Specific implementation

[0022] 1. AC 220V power supply passes through transformer T1 to generate AC 16V power supply. AC16V power input D25 rectifier bridge (2W10) input terminal. The output terminal 4 of the D25 rectifier bridge is connected to the input terminal 1 of U23 (7815). Terminal 2 of D25 is grounded. E02 is the input stable voltage of U23, which plays a role of voltage stabilization and filtering. Terminal 2 of U23 is grounded. The 3 end of U23 is the output end, output 15V power. E01 and C13 stabilize the 15V power supply and filter the harmonics of the 15V power supply to stabilize the 15V power supply. The 15V power is converted to 5V voltage by U05. E05, C03 play the role of stabilizing 5V power supply. R78 plays a feedback function to stabilize the output (such as figure 2 ).

Abstract

The invention relates to an intelligent high-efficient control apparatus that is applied to the mechanical field. With the apparatus, a problem that a relay can not work stably when the AC 220-V working voltage is not stable can be solved. According to the scheme, a control circuit using an AT89S52 single-chip microcomputer as a core sends a corresponding signal to drive a relay circuit, thereby deciding whether the relay works. On the basis of combination of a DS1302 clock chip and an AT24C02FLASH memory, information of the year, month, date, week, hour, minute, and second is displayed. Meanwhile, automatic adjustment and power-down protection of the information are completed and all information is displayed by a liquid crystal unit; and real-time control of the relay can be realized. The input interface is realized by three keys that are used for adjusting the data and time and setting on / off of the alarm and the time of the alarm. The alarm function is realized by a buzzer. The provided intelligent high-efficient control apparatus is mainly applied to control of a relay of mechanical processing equipment.

Description

technical field [0001] The invention relates to the field of machinery, in particular to lathe and grinder equipment. Background technique [0002] At present, most of the equipment control in the machining industry uses relays composed of AC220V coils to control the work of equipment. When the working voltage AC220V is unstable, it will cause the relay to work intermittently, which in turn will cause the machining equipment to work intermittently. If it stops at any time, the direct consequence is that the processed parts are unqualified. Unnecessary increase in production costs for the company. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the present invention provides an intelligent high-efficiency control device, which solves the problem of unstable operation of relays in machining equipment. An intelligent and efficient control device takes the AT89S52 single-chip microcomputer as the core to form a singl...
