The power supply of described recording equipment is direct current+5V, can be by the external direct current power supply power supply or by PC USB confession electricity; Optical coupling isolation circuit can adopt the TLP421 chip; Communicating circuit can adopt the Max232 chip to realize the RS232 communication; Embedded controller can adopt the MCS51 series monolithic, but external direct current power supply, crystal oscillator, reset circuit consist of single-chip minimum system; Real Time Clock System can adopt the DS1302 chip; The power down nonvolatile programmable memory can adopt the AT24C64 chip; Single-chip microcomputer is connected with TLP421 chip, DS1302 chip, AT24C64 chip by common IO mouth, is connected with the Max232 chip with TXD by RXD.
Described recording equipment is by RS232 bus or RS485 bus, or usb bus connects described PC.
When non-extruding event appears in described recording equipment judgement aluminium extrusion equipment, the information such as time started of event and duration are sent to described PC.Operating personnel determine reason and the classification that this non-extruding event occurs, and all event informations are deposited in database.PC generates non-extruding event EXCEL file, the document is preserved the full detail of all the non-extruding events in section seclected time, built-in grand function with function of statistic analysis, the manager can carry out labor on other PC, with graph mode display analysis result.Described recording equipment is temporarily stored in non-extruding event information in memory with described PC communicating interrupt the time, and after communication recovered, the information of keeping in sent to PC successively.
The aluminium extrusion device controller PLC need to provide one or more output contacts; Recording equipment can read the state of a plurality of output contacts of PLC, judges whether to occur non-extruding event, and passes through RS232 or RS485 or usb bus and transmit non-extruding event information to PC; The PC management staff of teams and groups, systematic parameter and extrusion equipment parameter are set, preserve non-extruding logout in database, generate the statistical analysis document.
The below describes the method for the non-extruding event recording system of this aluminium extrusion equipment in detail, comprises the steps:
Step 1: the running status of obtaining aluminium extrusion equipment:
,, judge whether aluminium extrusion equipment is in non-squeezed state, and control one or more output contacts as extruding force, extrusion speed according to current extruding operational factor by aluminium extrusion device controller PLC;
Step 2: judge whether to occur non-extruding event, and time started and the duration of this event:
Recording equipment obtains the state of aluminium extrusion device controller PLC output contact in described step 1 by the input optical coupling isolation circuit; Recording equipment is analyzed this state and variation thereof: transferred to by operation when squeezed state and stopping, after duration surpasses " the fixedly dead cycle time " of extrusion equipment, think non-extruding event to occur, and in conjunction with the Real Time Clock System of recording equipment, the time started that draws non-extruding event; When stopping transferring to operation, think that current non-extruding event finishes, and calculates the duration of this event when squeezed state;
Step 3: recording equipment sends non-extruding event information to PC:
Recording equipment is by the RS232 bus, or the RS485 bus, or usb bus is the information of the non-extruding event that obtains in step 2, and the communicating circuit by predetermined communications protocol by recording equipment sends PC to;
Step 4: when PC is received non-extruding event information, this information is processed, preserved the information relevant to non-extruding event in database:
PC is managed production before certain teams and groups of teams and groups begin to produce, and needs login system, becomes current production team; PC is according to characteristics and the non-extruding event type of gerentocratic requirements definition of extrusion equipment; When PC is received non-extruding event; operating personnel are according to the actual shutdown reason of current extrusion equipment; select predefined non-extruding event type; and with the information of time started of non-extruding event, duration, current teams and groups, current use mould, current extruded product, be saved in database.
Step 5:PC machine generates the convenient document for the manager: the report file that PC generates is the EXCEL file, preserves the information of all the non-extruding events in section seclected time, and the built-in grand function of EXCEL with function of statistic analysis; When the manager selectes the time period more specifically in report file after, the built-in grand function of EXCEL with function of statistic analysis will re-start analysis according to the new time period automatically, with graph mode display analysis result.
Further, when PC breaks down, the recording equipment normal operation, after non-extruding event and temporal information thereof being detected, the relevant information of this event is pressed the sequencing of time, form with blotter is kept in the power down nonvolatile programmable memory of recording equipment, preserves simultaneously the index information of blotter; After PC recovered normal operation, recording equipment was according to above-mentioned index information, and the information of non-extruding event is sent to PC, by the described method of step 4, confirmed one by one and preserve the information of non-extruding event by operating personnel.
In the utility model; PC is analyzed the non-extruding event in the certain hour section; the statistics extrusion equipment is in the certain hour section in production process; the frequency of various non-extruding events, accumulative total duration; analyze each production team actual production efficient; and by certain hour length as monthly generating report file; analyze main cause and the order of severity thereof of pinch equipment downtime for the manager; being beneficial to the manager takes for measure; reduce dead cycle time, improve the actual production efficient of extrusion equipment.
The report file that PC generates, it is for example the EXCEL file, has built-in statistical analysis function, comprise in the fixed time section information as all the non-extruding events in certain month, the manager can carry out more careful analysis in the situation that break away from native system, as limiting the time range in a certain week, built-in statistical analysis function re-starts analysis according to the new time period automatically, with graph mode display analysis result.
The utility model is in conjunction with PLC technology, embedded system technology, PC visual programming technology, database technology, to help the extrusion equipment administrative staff effectively to understand frequency and the duration of non-extruding event, conscientiously understand the actual production efficient of extrusion equipment, understand the actual production efficient of each different teams and groups, the aluminium extrusion equipment huge for cost of investment, that operating cost is very high, the small size raising of actual production efficient, just can bring the remarkable reduction of cost, bring very large economic benefit.
The above is only better enforcement use-case of the present utility model, is not be used to limiting protection domain of the present utility model.All within spirit of the present utility model and principle, any modification of doing, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
