The beneficial effect of this programme can be learnt according to the narration to such scheme, concrete stirs watch-dog by adopting big capacity USB storage, the internal USB dish is used for the data of duty to be preserved, and external USB interface connects external USB dish and is used for data transfer and data backup.Adopt Chinese, English, digital input function to realize the effect of industrial control computer in concrete stirring control.For heavy construction class concrete mixing plant, be fit to the site environment at engineering station more with its cost, special use, odds ratio industrial control computer such as easy-to-use, small and exquisite.For the large-sized concrete mixing plant, from further raising mixing plant reliability, satisfy the production demand that large-scale casting concrete production can not be interrupted and set out, as the alternate products of industrial computer, be equipped with use cost mutually than two industrial computers and reduce.Concrete stirs supervisor applications in medium and small concrete mixing plant, has solved data record and has preserved imperfection, and memory data output is little, problem that can't long preservation.Realize long-term perfect preservation of the record of production, improved the monitoring capacity of production process simultaneously.Therefore the utility model has compared with prior art been realized technical purpose.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the utility model hardware block diagram;

Fig. 2 is the utility model circuit diagram;

Fig. 3 is the keyboard schematic diagram;

Fig. 4 is a keyboard input program block diagram;

The specific embodiment

The utility model is the combination with functions such as man-machine interface (LCDs, keyboard), communication monitoring, data record storage, printings.The system hardware block diagram is seen Fig. 1, The whole control adopts concrete to stir watch-dog and concrete stirs the mode of controller combination, wherein stir the block diagram of watch-dog in the frame of broken lines for concrete, concrete stirs watch-dog and concrete stirs employing RS232 communication between the controller, realizes concrete is stirred the monitoring of control appliance by serial communication.Concrete stirs watch-dog is responsible for production task in system layout, the demonstration of production information, record, inquiry, printing, the real-time monitoring of production process; Concrete stirs controller is responsible for in-site measurement, actuating unit in system direct control.

Concrete stirs the watch-dog schematic diagram and sees Fig. 2, and wherein single-chip microcomputer adopts the mega series monolithic of atmel corp, as ATMEGA128; The Chinese character font memory circuit adopts the little sector flash chip (AT29C040 or AT29C020) of atmel corp; The data record of concrete production process is kept in the internal USB dish, and usb circuit is selected homemade chip CH375 for use, can shift the data in the internal USB dish or back up easily by external USB dish; LCD and keyboard combination are moulded on the shell at one, and as shown in Figure 3, the 4*5 keyboard is supported Chinese, English and numeral input; Support data to print by parallel interface; The power supply power supply provides by the connection winding displacement that serial communication circuit and concrete stir between the controller.

The increased functionality point of this concrete stirring watch-dog is the disposal ability and the mass data storage ability of text message, and the physical circuit of this part is seen Fig. 2.Chinese character font storage chip AT29C040 memory capacity is the 512k byte, because single-chip microcomputer expansion RAM maximum address space is 64k, the memory space of 512k is divided into the address field of 16 32k, the low order address line A0-A14 of AT29C040 is connected on the address bus of single-chip microcomputer, high address line A15-A18 is connected on the I/O mouth of single-chip microcomputer, as the chip selection signal of each 32k address field, realize addressing to whole 512k space.The WR pin of AT29C040 directly connects high level, prevents that mistake from writing.The spelling input method of composite keyboard is adopted in the input of text message, and the keyboard schematic diagram is seen Fig. 3, adopts number group record identification phonetic key combination, this subprogram flow process is seen Fig. 4, the zero clearing of original state array when detecting button, is appended key assignments to array, and pinyin combinations and Chinese character that retrieval meets show, if do not meet, in array, remove last time button, continue to detect button, up to the desired Chinese character of input, last array zero clearing.

Usb circuit CH375 selects for use its parallel port to be connected with single-chip microcomputer, connecting circuit is seen Fig. 2, can detect whether USB dish connects by CH375, information such as the file in the USB dish, residual capacity, can on the USB dish, create new file by CH375, in file, preserve data.CH375 is homemade integrated circuit, and producer provides the basic file operation built-in function, can directly call.Stir in the concrete application of watch-dog at concrete, on the USB dish, create a new file every month, each file is preserved one month data record, USB dish data can backup on other computers easily, also can directly consult production information in the past on concrete stirs the LCD of watch-dog.

Concrete stirs work and the function realization that watch-dog is finished in the concrete production process:

(1), prescription writes, preserves, the 99 cover prescriptions that prestore, power down is not lost, and is kept in the electricallyerasable ROM (EEROM) (EEPROM) of single-chip microcomputer.

(2), the production task layout, 5 production tasks that prestore start to be produced the back concrete and are stirred watch-dog and send the control data of article one task to the concrete production controller, send next bar task after first task is finished automatically, 5 tasks are produced in turn automatically.The production task layout can be passed through spelling input method, supports Chinese, English and digital information input, except that preserving data such as prescription, variable, setting value, error, can also preserve management datas such as engineering name, contract information, customer information, information of vehicles.

(3), whenever finish a concrete concrete production, concrete stirs controller the actual metered data is sent to concrete stirring watch-dog, and concrete stirs watch-dog reception data and is saved in the internal USB dish, outputs to printer simultaneously.According to present clock, create a file every month when concrete stirs watch-dog preservation data, record of production data are saved in the file by text mode, and single-chip microcomputer is saved in file in the internal USB dish by usb circuit.

(4), concrete stirs the status information that watch-dog shows concrete stirring controller, inquiry also is provided with the control parameter that concrete stirs controller, the test concrete stirs the switching value input and output state of controller, the calibration concrete stirs the weighing equipment of controller, shows that in real time concrete stirs the scale Value Data that controller is uploaded.
