input

1,2,3,4,5,6,7 of integrated circuit (IC) 5 respectively, and the pin 1～8 of integrated circuit (IC) 2 connects two groups of

inputs

1,2,4,8 of toggle switch K3 successively.The pin 16,17 of integrated circuit (IC) 2 connects two cutter contacts of standard K switch 2.The output 8,9 of integrated circuit (IC) 5 joins through R18, R19 and amplifier a, c respectively, the pin 10,11 of integrated circuit (IC) 5 joins with the input of relay J 2, J1 respectively, normally closed, the normally opened contact of relay J 1 connects respectively regularly opens socket Z2, the normally opened contact of relay J 2 loudspeaker Y taking alarm.

Attaching plug 3 is connected with the mains, closed mains switch K1, the utility model is in running order, LED 1 is luminous, read in the back judgement by four kinds of scheme logics that standard K switch 2 is formed for CPU read-write line, work, constitute four kinds of time A, B, C, D standard in programming mode certainly.By standard K switch 2 select time standards, by binary digit toggle switch K3 ON/OFF decimal number (0～9) is become 8421 yards D/O for CPU and reads in to establish to give and put from programming the ON/OFF time parameter, by standard K switch 2 and toggle switch K3, regularly close socket Z1, regularly open socket Z2 and form 800 kinds of times jointly and make up.Main pulse inputs to CPU through integrated circuit (IC) 5 when two kinds of produced by the CPU program 0.2 second and 2 seconds, to provide 0.4 second～36 hours regular time parameter, adopts preferred time parameter generation toggle switch timetable 2, and timetable 2 is listed on the shell 1.The utility model gives when putting work by standard K switch 2 and toggle switch K3, send regularly on/off commands provides relay J 1 through serial input port and integrated circuit (IC) 5 operating state by the CPU program, because socket Z1 is closed in timing, timing is opened socket Z2 and formed opposite each other on off operating mode, thereby realized timing machine open/close and periodic duty state within 36 hours.

Amplifier a; b forms the overvoltage detection comparator; amplifier c; d forms under-voltage detection comparator; as input sample voltage ui during greater than comparative voltage E1 or less than comparative voltage E2; amplifier a then; c exports high level; through integrated circuit (IC) 5; pin 12 in integrated circuit (IC) 2; 13 produce overvoltage; under-voltage response; under program control; pin 14 output alarm signals of integrated circuit (IC) 2; promote relay J 2 actions through integrated circuit (IC) 5; indicator light LED3 is luminous; loudspeaker Y is sent chimes of doom, and integrated circuit (IC) 2 pin 20 send interrupt signal simultaneously, promotes relay J 1 action; make and regularly close socket Z1; regularly open socket Z2 outage, thereby finish overvoltage; under-voltage protection function.
