Abstract

The utility model discloses a star triangle starting time delay setting system. The system comprises a single chip microcomputer, a hardware control module and a motor. The single chip microcomputer is connected with the hardware control module. A dial switch used to set delay time is comprised. The dial switch is connected with the single chip microcomputer. The system of the utility model has the advantages that through combination usage of the dial switch and the single chip microcomputer, time-delay starting time control precision is increased to a second error which is less than 1% so that the time-delay starting time control of the system is accurate.

Description

A kind of star triangle start time-delay arranges system

Technical field

The utility model relates to a kind of delayed startup system.

Background technology

Existing motor is star-like-and triangular form starts, formed by institutes such as the time relay, auxiliary relays mostly, relay control system relies on the action of mechanical contact to realize, operating frequency is low, even the switch motion of contact is generally at a millisecond order of magnitude, and the mechanical contact problem that also can occur shaking.In addition, relay control system is used a large amount of mechanical contacts, and there are phenomenons such as mechanical wear, electric arc burn in the contact when opening and closing, the relay life-span is not long, and poor reliability makes start-up time delay control can occur than mistake, cause problems such as system delay fault, cause economic loss thus.

The utility model content

The purpose of this utility model is to provide a kind of accurate more star triangle start time-delay of time control of delayed startup that system is set.

For realizing that the technical scheme that the purpose of this utility model adopts is: a kind of star triangle start time-delay arranges system, comprise single-chip microcomputer, hardware controls module and motor, single-chip microcomputer is connected with the hardware controls module, comprise that also one is used for setting the toggle switch of delay time, described toggle switch is connected with single-chip microcomputer.

The utility model is set start-up time delay by toggle switch, and the pin of toggle switch is exported corresponding signal, for single-chip microcomputer is imported corresponding electric potential signal; Single-chip microcomputer is handled the signal of toggle switch, and the result after will handling preserves, and when reaching setting-up time, flows to motor by the hardware controls module; Motor carries out the conversion of star triangle according to the control mode that the user sets.

Described toggle switch includes but not limited to 5 outer inputs, and the start-up time delay that the more many maximums of input can arrange is just more long, can select the not toggle switch of isotopic number as required for use.

The outer input of described toggle switch is connected with single-chip microcomputer, and perhaps the outer input of toggle switch is connected with the expansion input I/O mouth ways of connecting of single-chip microcomputer.

Described single-chip microcomputer is sent to motor by the hardware controls module with the control signal of delaying time.

Preferably, described single-chip microcomputer is sent to motor by the hardware controls module with the control signal of delaying time when next secondary star triangle is changed.

Described single-chip microcomputer and hardware controls module are integrated on the same PCBA, each circuit module zone of silk-screen on PCBA, and make that wiring is simple more, avoid false wiring, circuit layout is also more attractive in appearance.

The hardware controls module comprises digital input module, digital input module, analog input module and analog output module.

Described PCBA is provided with the plug terminal with external cabling, and peripheral hardwares such as motor can insert this delayed startup control system by plugging terminal.

Compared with prior art, the utility model advantage is: use by toggle switch and single machine combination, with the precision improvement of start-up time delay control to second error less than 1%, make the time control of control system delayed startup more accurate.

Description of drawings

Fig. 1 arranges the structural representation of system for the time-delay of the utility model star triangle start;

Fig. 2 is the utility model embodiment toggle switch and single-chip microcomputer connection diagram.

Embodiment

Below in conjunction with accompanying drawing specific embodiment of the utility model is described further:

As shown in Figure 1, this star triangle start time-delay arranges system and comprises a PCBA and motor 5, described PCBA is formed through encapsulation by a PCB circuit board, is welded with the circuit of single-chip microcomputer 1, toggle switch 2, hardware controls module 3 and plug terminal 4 correspondences on this PCB circuit board; The circuit connecting relation that prints on the PCB circuit board is, single-chip microcomputer 1 is connected with toggle switch 2, hardware controls module 3 respectively, hardware controls module 3 comprises numeral input, digital output, analog input and analog output module, and motor 5 is connected with hardware controls module 3 by plug terminal 4.

Fig. 2 is present embodiment toggle switch and single-chip microcomputer connection diagram, toggle switch 2 is 5 toggle switch, it also can be the toggle switch of other figure places, toggle switch 2 is by 5 corresponding 5 input I/O mouths that connect single-chip microcomputer 1 of outer input pin, perhaps the outer input of toggle switch 2 is connected other 5 pin ground connection with the expansion input I/O mouth (the input I/O mouth of expansion single-chip microcomputer can be realized by for example single-chip microcomputer 1 and other a slice microcontroller serial port ways of connecting) of single-chip microcomputer 1.When needs change the operating state of motor 5, at first allow single-chip microcomputer 1 power on, make the in running order wait instruction of single-chip microcomputer 1 internal reset program; The user sets start-up time delay by stirring toggle switch 2 then, 5 pins by toggle switch 2 are exported corresponding signal, change the level state of single-chip microcomputer 1 respective pin, 5 input I/O mouths of single-chip microcomputer 1 are handled the signal of toggle switch 2 each pin inputs respectively, obtain representing binary data of decimal number 0 to 31 any one numerical value, these data can satisfy the time requirement of motor star-triangle conversion, and the data after single-chip microcomputer 1 will be handled are preserved; When motor 5 need carry out the conversion of star-triangle, single-chip microcomputer 1 is according to the last time that arranges of user, also be the binary data that single-chip microcomputer 1 is preserved, the instruction that will control motor 5 working methods by the hardware controls module is sent to motor, thereby reaches the purpose of accurate control.

The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change and revise above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.
