Below in conjunction with drawings and Examples the utility model is further described:

Description of drawings:

Fig. 1 is the theory diagram of a kind of boiler failure signal recorder of the present utility model

Fig. 2 is the boiler failure signal recorder electrical schematic diagram in the utility model.

The specific embodiment:

Fig. 1 has described the principle of a kind of boiler failure signal recorder of the present utility model.It is to be made of 220V control signal (eight tunnel) circuit [or 110V control signal (eight tunnel) circuit, 12V control signal (eight tunnel) circuit, 6.3V control signal (eight tunnel) circuit] 8, rectification, variable voltage signal treatment circuit 9,89C51 singlechip microprocessor 1, I/O interface circuit 2, DS12887 calendar clock chip 3,32K data memory 4, rechargable power supplies (12) 5 RS232 communication interfaces 6 and PC computer 7 and corresponding support software.

The boiler control signal has several control voltages such as 220V, 110V, 12V, 6.3V, in order to make instrument can be suitable for various control circuits, in Fig. 1, Fig. 2, this several states have all been designed treatment circuit before the signal input, after rectification, transformation to input interface I/O.For the ease of distinguishing the signal classification, eight kinds of malfunctions (also being the control circuit state) called after IN0 with boiler, IN1, IN2, IN3, IN4, IN5, IN6, IN7 directly links eight input pins of I/O, the 89C51 processor receives (IN0 behind the fault-signal ... IN7), trigger constantly through high level to the generation of clock chip read failure, this is deposited in the stored data group of certain fault constantly, after this fault-signal disappears (line status becomes low level by high level), the 89C51 processor reads once to clock chip again and constantly is deposited in the same group of data, and per two data are a data group.The 32K memory is divided into eight fault-signal storage portions, and each storage portions is represented independently signal implication.Concrete function is ensured by upper software design.

Data have designed special-purpose database support software by the output that links to each other with PC of RS232 communication interface in the PC, this software has read data from hardware, sets up database, analysis, statistics and screening function.

The utility model is by the combination of computer software and hardware, with the boiler failure signal automatic acquisition, storage, and output is carried out Macro or mass analysis in computer (PC), it is characterized in that: the fault-signal of boiler control circuit is delivered directly to the I/O interface after signal processing module is handled (no analog-to-digital conversion), store after by microprocessor this signal being ironed time mark, regularly add up by communication interface input computer (PC), analyze, comprise signal processing module, the I/O interface, 89C51 single-chip microcomputer (CPU), the DS12887 calendar clock chip, data memory, rechargable power supplies, RS232 communication interface and computer (PC) support software.Fault-signal to be taking place constantly and the form constantly that stops is stored in the data memory, and data are the flow-type storage, i.e. after the data of signal element storage was full, the data that deposit in were at first overflowed earlier, have up-to-date data in the memory all the time.Signals collecting part (being installed in the boiler console) does not contain Presentation Function and printing function, and data gather, analyze and print by PC computer (public instrument).

The technology that the utility model utilizes computer software and hardware to combine, a kind of boiler failure signal recorder (boiler black box) is provided, this record only can accurately be gathered and flow-type writes down the fault-signal that occurs in the boiler running process, data in the recorder use portable computer (supporting special-purpose software) to deposit Computer Database in by the output interface of recorder by managerial personnel, add up, analyze.

Industrial Boiler self has more perfect electric control system, the function of its major control circuit is identical, the control circuit output all has signal to be connected to panel do to show signal input (signal lamp, various Displaying Meter), circuit break, open the actual motion state that (electricity is arranged, do not have) can reflect boiler substantially.Boiler failure signal recorder (boiler black box) is originated as signal with the circuit state of electrical system, directly uses the data signal of circuit state (high level, low level) as this device.

The 32K data file is divided into eight data groups, divides equally 4K for every group, and every group can be stored 4096 fault datas simultaneously, the fault-signal more than round of visits of sustainable storage (being generally 6 to 12 months).Output system employing RS232 communication connects and directly is connected with portable computer day.Software has upper, the next two softwares, making software down is the software kit of support hardware operation, the function of upper software be with the transfer of data in the hardware in portable computer and set up Mishap Database, have function of statistic analysis simultaneously concurrently.
