Abstract
A programmable time delay relay is composed of a programmable control module and an electromagnetic relay, wherein the programmable control module comprises a data memory, a level conversion chip RS232, a microcontroller and a relay drive circuit, the data memory is directly connected to an I/O port of the microcontroller, a TTL (transistor-transistor logic) connecting end of the level conversion chip RS232 is connected to a serial communication interface of the microcontroller, the other end of the level conversion chip RS232 is directly led out and connected with a serial communication interface of a computer, and the relay drive circuit is respectively connected with the I/O port of the microcontroller and the relay. The invention makes the time delay relay communicate with the computer, and realizes the purpose that the product can be programmed on line.
Description
One, technical field
The invention belongs to the time-delay relay technical field.
Two, background technology
Time-delay relay has obtained extensive use as a kind of important automation control element in various control system.The control mode of time-delay relay is broadly divided into following several at present:
1, RC time-delay mode (claiming analog again)
2, counting frequency division formula
3, microcontroller (being commonly called as single-chip microcomputer) control type
But these three kinds of time-delay relays have a common shortcoming: in a single day product finishes assembling, and the type of then delaying time and delay time are all definite, can't change.
Three, summary of the invention
The present invention seeks to shortcoming, a kind of time-delay relay that can off-line programing is provided at conventional time-delay relay.
Programmable time delay relay of the present invention comprises: common electrical magnetic relay, programmable control module, described programmable control module comprises data memory, level transferring chip, microcontroller and relay drive circuit, data memory directly is connected on micro controller I/O mouth, the TTL link of level transferring chip is connected on the serial communication interface of microcontroller, the other end is directly drawn, be connected with the serial communication interface of computer, relay drive circuit links to each other with micro controller I/O mouth and relay respectively.
The present invention makes time-delay relay and computer carry out communication, but has realized the purpose of product online programming.
Description of drawings
Fig. 1 is a programmable time delay relay structured flowchart of the present invention;
Fig. 2 is a programmable control module structured flowchart among the present invention;
Fig. 3 is microcontroller software flow block diagram when relay work among the present invention.
Fig. 4 is microcontroller software flow block diagram when relay need change delay parameter among the present invention.
Embodiment
Programmable time delay relay of the present invention comprises common electrical magnetic relay and programmable control module, described programmable control module comprises data memory, level transferring chip, microcontroller and relay drive circuit, data memory directly is connected on micro controller I/O mouth, the TTL link of level transferring chip is connected on the serial communication interface of microcontroller, the other end is directly drawn, be connected with the serial communication interface of computer, relay drive circuit links to each other with micro controller I/O mouth and relay respectively.
The microcontroller software flow process is seen Fig. 3.When the product operate as normal, serial ports interrupts opening by software, and at this moment microcontroller directly calls in the memory line delay of going forward side by side of the data in the relevant memory cell, after delay time has arrived, drives relay work.Its software flow is: beginning-open string mouth interruption-memory read-time-delay-driving relay-end; When needs change programmable time delay relay time-delay type, delay time, with the serial communication link of programmable time delay relay is that RS232 level die terminals is connected on the serial communication interface of computer, microcontroller at first sends " being ready to " instruction to computer by its software flow, the notice computer sends related data, when microcontroller is received the data that computer sends, related data is stored in the memory, finish the change of time-delay type, delay time, proceed the operate as normal program then.
