Description

The economical dual-delay time relay

The utility model relates to a kind of time relay.

At present, the time relay on the market is analog mostly, as shown in Figure 1, it is mainly by output control module, central authorities' timer and input setting module are formed, output control module is common relay, central authorities' timer is an analog timer, mainly there is following shortcoming in it: analog timer adopts the method for hardware to realize time set, usually adopt some oscillation frequency dividing circuits to finish, but the oscillation frequency dividing circuit precision is lower, often can only reach 0.1 second the order of magnitude, and setting range is limited, poor anti jamming capability makes troubles so for actual work; Import setting module in addition and realize with knob resistance usually, knob resistance operation control difficulty, the accuracy of time is difficult to control; A kind of digital time relay has just appearred now, adopt the input of liquid crystal display displays time to set, with keyboard as the input setting module, the interface complexity, volume is bigger, troublesome poeration, structure is comparatively complicated, and cost is higher, can only realize single time-delay, promptly can only control output control module and carry out the time-delay of action, and can not control the time-delay that output control module stops to carry out action.

The purpose of this utility model provides a kind of economical dual-delay time relay, and it realizes the plesichronous time-delay by the method for software, reaches the purpose of time control, the accuracy height, realize Based Intelligent Control, stability is better, and the interface is simple, processing ease, volume is little, and cost is low.

The utility model is achieved by the following technical solution: it comprises output control module, central timer, input setting module and power supply, this central authorities' timer is a microprocessor, the input setting module is a dial-up, it also comprises the unit setting module in addition, the output of microprocessor is connected with the input of output control module, the unit setting module is connected with microprocessor, and the output of dial-up is connected with the input of microprocessor.

Above-mentioned dial-up is divided into two groups, is respectively applied for to set the delay time that output control module is carried out action or stopped to carry out action.

The utility model compared with prior art has following advantage: 1) utilize the software of microprocessor to realize timing, reach the purpose of time set, complete Based Intelligent Control, because microprocessor native instructions execution speed is fast, so the minimum magnitude of the time of setting is 0.01 second, the precision height, the scope of setting is wide, can set the time delay by 0.01 second to 99.9 seconds, antijamming capability is strong, good stability; 2) carry out time set by dial-up, operation accurately, easily, objective interface, 3 dial-ups of last row are used to set the delay time that output control module disconnects, arrange the delay time that 3 dial-ups are used to set the output control module closure down, reach two purposes of setting, in addition the LCD of dial-up replacement, simplify product structure, reduced cost; 3) increased the unit setting module, by the unit of the unit of slide switch conversion time and light-emitting diode instruction time and the state of output, more directly perceived; 5) realize the output auto-reset function, use more convenient; When 6) 3 dial-ups settings of row delay time was zero down, relay output kept, up to reset pulse is arranged.
