timer

Abstract

The invention provides a timer for carrying out remote parameter adjustment at any moment through bluetooth equipment. The timer comprises a single-chip microcomputer, a clock signal generation circuit, a memory used for the single-chip microcomputer to read-write timing information, a relay, a control switch, a display, a bluetooth module used for communication connection with external equipment and a power circuit used for providing a DC power for each functional circuit. The display is connected with a display output end of the single-chip microcomputer. A normally open contact of the relay is used for connecting a power supply terminal of an executive component. The invention has beneficial effects as follows: the timer can be remotely operated by mobile hand-held equipment such as a handset and the like, and parameters can be adjusted at any moment; and the timer is convenient to use and has a wide application range.

Description

technical field [0001] The invention relates to the field of timers, in particular to a timer capable of remote parameter adjustment at any time through a bluetooth device. Background technique [0002] Timers are widely used in the fields of intelligent control of household appliances and industrial control, but their parameter control generally needs to be manually adjusted through the man-machine interface at the site where the timer is located. For example, the utility model patent with the patent number of 200720119491. Single-chip microcomputer, control device with relay, display device, input terminal with buttons, set relevant timing parameters through buttons, and control the on-off of the relay when the timing time is full, and then control the opening and closing of the execution parts to regularly open or close the execution parts. Function, this type of timer has the disadvantages that it cannot be set remotely and has a single function. Contents of the invent...
