Abstract
The utility model provides a belt slip protection trouble emergency treatment device, the single chip microcomputer output that is connected with power supply circuit and awaken up/close the button respectively passes through output interface circuit and connects the output instruction, and output interface circuit forms single chip microcomputer feedback control circuit through output line and online detection circuitry simultaneously, is equipped with emergency treatment program control module in the single chip microcomputer. The utility model discloses safe and reliable, simple and easy can shorten the fault handling time when the protection device trouble that skids appears in the belt normal operating process, can make the belt start immediately when emergent, handles the trouble again when waiting for the time to allow to guarantee the continuity of production.
Description
Technical field
The utility model belongs to industrial electric automation field more particularly to a kind of belt slippage protection failure emergency processing
Device.
Background technique
The principle of belt slippage protection is to have detected whether that rotational pulse signal is spread out of on follower, in normal operation
Belt follower is rotation, and when slipping phenomenon occurs between driving wheel and belt, when belt does not rotate, follower just can not
Rotation, to can't detect pulse signal.
Since site environment is severe, detection device is caused to break down sometimes, rotational pulse signal can not be correctly obtained.Skin
Accidentally machine halt trouble occurs for band machine, influences to produce.It deals with both laborious and time consuming.
Summary of the invention
The utility model, which is intended to provide one kind, can be such that belt emergency starts immediately, shorten fault handling time, guarantee production
Failure emergency treatment device is protected in successional belt slippage.
For this purpose, the technical solution that the utility model is taken are as follows:
A kind of belt slippage protection failure emergency treatment device, including power circuit, wake-up/close button, single-sheet miniature
Computer, output interface circuit, output instruction, outlet line and on-line checking circuit；Respectively with power circuit and wake-up/closing
The one chip microcomputer output end of button connection connects output instruction by output interface circuit, and output interface circuit leads to simultaneously
It crosses outlet line and on-line checking circuit forms one chip microcomputer feedback control loop, be equipped with and answer in one chip microcomputer
Anxious processing routine control module.
The power circuit is using CR2 type 2.5~3.5V lithium battery as power supply.
The output interface circuit is made of photoisolator, thyratron transistor and coupling resistance.
The output instruction forms pulse indicating circuit using LED light emitting diode, current-limiting resistance.
The on-line checking circuit is made of transistor, step-down capacitor and resistance.
The utility model has the following beneficial effects:
The utility model is safe and reliable, simple and easy, and protective device event can be had skidded in belt normal course of operation
When barrier, shorten fault handling time, when emergency can be such that belt starts immediately, allow Shi Zaihang handling failure to the time, to guarantee
The continuity of production.
Detailed description of the invention
Fig. 1 is belt slippage protection failure emergency treatment device structural block diagram.
Specific embodiment
As seen from Figure 1, failure emergency treatment device, including power circuit, wake-up/pass are protected in the utility model belt slippage
Close button, one chip microcomputer, output interface circuit, output instruction, outlet line and on-line checking circuit；Respectively with power supply
The one chip microcomputer output end that circuit is connected with wake-up/close button connects output instruction by output interface circuit, defeated
Outgoing interface circuit passes through outlet line simultaneously and on-line checking circuit forms one chip microcomputer feedback control loop, and monolithic is micro-
Emergency processing program control module is equipped in type computer.
Power circuit, as power supply, cooperates emergency starting program controling module to make circuit not using CR2 type 3.0V lithium battery
Enter dormant state not power consumption when work.It is online that equipment can be automatically detected when emergency starting device accesses circuit, and from
It is dynamic to enter working condition, issue skidding analog pulse signal.
Output interface circuit is made of photoisolator MOC3041, thyratron transistor BT138-600E and coupling resistance, real
The impulse level that now one chip microcomputer is sent is transformed into the analog switch signal that outside line can work.
Output instruction forms pulse indicating circuit using LED light emitting diode, current-limiting resistance.
On-line checking circuit is made of transistor S8050, step-down capacitor and resistance.Emergency starting device is accessed
The voltage signal of the power supply of AC220V is converted into the level pulse that one chip microcomputer can identify, gives single-sheet miniature calculating
Machine identifies whether equipment is online.
Outlet line uses 1.0 square millimeters of soft copper conducting wires of BVR.
Wake-up/close button can open emergency treatment device manually and enter working condition, or close emergency treatment device
Enter dormant state.
It is equipped with emergency processing program control module in one chip microcomputer, whether can access electricity with automatic checkout equipment
Road detects and immediately enters working condition after line.30s can be transferred to dormant state automatically after emergency treatment device is removed, and guarantee
Battery not power consumption.Working condition issues the on-off signal that duty ratio is 1:1 from output port, and driving output interface circuit issues mould
Quasi- skidding pulse signal.Pass through skidding simulator, it may be convenient to when belt slippage protection is broken down, emergency starting skin
Band machine.
The access point of the utility model belt slippage protection failure emergency treatment device can be scene close to switching circuit,
It is also possible to switchgear house skidding relay egress line.It is easy to use quick, moment can bypass the skidding broken down
Protective device starts belt feeder immediately.
