The invention discloses a shared printing method of printers for intelligent devices in a transformer substation, which is implemented based on a network system consisting of a set of intelligent devices. The key of the method is as follows: a printing controller with a CPU (central processing unit) and a management program is added in the network system, wherein the set of intelligent devices is connected with the printing controller by aid of a RS485 bus, and the printing controller is connected with a printer by aid of a RS232 serial interface; and a buffer is added in each intelligent device, so that the shared printing method is implemented based on the situation above. By using the shared printing method, the printing of operating information of each intelligent device is realized, and the cost and the space are saved, and meanwhile, the later maintenance of a whole printing system is also facilitated.
Description
Technical field
The invention belongs to the electric substation automation system technical field, relate in the transformer substation system smart machine to the Method of printing of service data, specifically the shared Method of printing of smart machine printer in the transformer station.
Background technology
In power industry, electric power facility inside such as power plant, transformer station are equipped with many automatic intelligent equipment, for example line protective devices, protection equipment for transformer, Small Electric Current Earthing And Routing Device etc.These automatic intelligent equipment need be printed some operation informations automatically at run duration; Traditional way is printer of each automatic intelligent equipment configuration; Each automatic intelligent equipment is printed the information of oneself separately; So not only caused cost, resource, and the significant wastage in space, also brought very big difficulty to plant maintenance.
In addition, when restrictions such as receiving cost, space can not be equipped with printer separately for each automatic intelligent equipment, just only give important automatic intelligent equipment configuration printer at present, the operation information of other equipment can't print.Like this, under the situation that can not give all automatic intelligent equipment configuration printers, can't write down the operation information of all devices, this has brought very big inconvenience for the running state real-time monitoring of smart machine.
Summary of the invention
The present invention is equipped with the pattern that printer prints for a smart machine that breaks traditions; And in order to solve the very big inconvenience that only brings for important smart machine outfit printer; Designed the shared Method of printing of smart machine printer in the transformer station; This shared Method of printing has not only been realized the printing to each smart machine operation information, and has practiced thrift cost and space, also is convenient to the later maintenance to whole print system simultaneously.
The technical scheme that the present invention adopts is: the shared Method of printing of smart machine printer in the transformer station; Realize based on the network system of forming by one group of smart machine; Key is: in above-mentioned network system, set up a print control unit that has CPU and supervisory routine; This group smart machine is connected by the RS485 bus with print control unit, and print control unit is connected by the RS232 serial line interface with printer, in each smart machine, sets up a buffer respectively; On this basis, the concrete steps of shared Method of printing comprise:
The information stores that a, smart machine will be printed is to the buffer of self;
The CPU intermittent cycle of b, print control unit is sent the inquiry print order information and is given each smart machine;
After c, smart machine were received the inquiry print command, whether content was empty in the management control unit query caching device of smart machine, if be not empty, then the type information of storing in the buffer is sent to print control unit through the RS485 bus, skips to steps d; If be empty, feedback signal that then will not have type information is sent to print control unit, skips to step b;
D, print control unit are sent to printer with the type information of receiving by the RS232 serial line interface and print.
The invention has the beneficial effects as follows: this shared Method of printing has not only been realized the printing to each smart machine operation information, and has practiced thrift cost and space, also is convenient to the later maintenance to whole print system simultaneously.
Description of drawings
Fig. 1 is a system architecture diagram of the present invention.
Fig. 2 is the control flow chart of the print control unit among the present invention.
Fig. 3 is the operational flowchart of smart machine among the present invention.
In the accompanying drawing, the 1st, 1-1,1-2 ... 1-n represents smart machine, and the 2nd, print control unit, the 3rd, printer, 4-1,4-2 ... 4-n represents buffer.
Embodiment
The shared Method of printing of smart machine printer in the transformer station; Based on by one group of smart machine 1-1,1-2 ... The network system that 1-n forms realizes; Importantly: in above-mentioned network system, set up a print control unit 2 that has CPU and supervisory routine; This group smart machine 1-1,1-2 ... 1-n is connected by the RS485 bus with print control unit 2, and print control unit 2 is connected by the RS232 serial line interface with printer 3, at each smart machine 1-1,1-2 ... Set up a buffer 4-1,4-2 among the 1-n respectively ... 4-n; On this basis, the concrete steps of shared Method of printing comprise:
A, smart machine 1-1,1-2 ... The information stores that 1-n will print is to self buffer 4-1,4-2 ... Among the 4-n;
The CPU intermittent cycle of b, print control unit 2 is sent the inquiry print order information and is given each smart machine;
After c, smart machine were received the inquiry print command, whether content was empty in the management control unit query caching device of smart machine, if be not empty, then the type information of storing in the buffer is sent to print control unit 2 through the RS485 bus, skips to steps d; If be empty, feedback signal that then will not have type information is sent to print control unit 2, skips to step b;
D, print control unit 2 are sent to printer 3 with the type information of receiving by the RS232 serial line interface and print.
The order that the inquiry print order information is sent in the described circulation of step b is to confirm according to the sequencing of the address in the address list pond of print control unit 2.
Described smart machine 4-1,4-2 ... 4-n has unique address.
When increasing new smart machine in the described network system, the address of the smart machine that this is new adds in the address list pond of print control unit 2.
Also be provided with ISD in the print control unit 2; On this basis; Print control unit 2 is temporary to ISD according to sequencing with the type information of receiving in the steps d, and is sent to printer 3 according to the order of the type information of storing in the ISD.
In the specific implementation, as shown in Figure 3, each smart machine 1-1,1-2 ... If the 1-n existence needs the information of printing, the information stores that then will print is to self buffer 4-1,4-2 ... Among the 4-n, and the state flag bit in the change buffer is " 1 "; If the information that need not print then state flag bit is changed to " 0 "; Then wait for the inquiry print command of print control unit 2.As shown in Figure 2, the CPU intermittent cycle of print control unit 2 is sent the inquiry print order information and is given each smart machine 1-1,1-2 ... 1-n is to realize each smart machine of poll; Then; After smart machine was received the inquiry print command, the content of state flag bit in the management control unit query caching device of smart machine was if be " 1 "; Then the type information of storing in the buffer is sent to print control unit 2 through the RS485 bus; Print control unit 2 is sent to printer with type information by the RS232 serial ports and prints, and after printing finished, print control unit was followed the next smart machine of poll; If be " 0 ", feedback signal that then will not have type information is sent to print control unit 2, and print control unit 2 is then inquired about next smart machine.
