Abstract

The present invention is a kind of analog signal printing interface, it changes into the print signal of printing function identification with analog electrical signal, directly drives the printer prints data, and this interface both can be made independently complete machine, also can make analog signal printer, directly the fishing dies analog signal.

Description

Analog signal printing interface technology and analog signal printer thereof

The present invention is the printer technology of electronic technology field.

In a lot of signal monitoring fields, not only need to show Monitoring Data, need to print these data simultaneously.Because the Data Input Interface of existing printer is digital, and general monitor signal is the analog electrical signal that converts to through various kinds of sensors mostly, so can not directly link to each other between printer and the monitor signal, the monitoring system that generally adopts Fig. 1 to constitute solves the printing problem of simulating signal.Among Fig. 1, analog electrical signal at first inputs to A/D converter 1 and converts digital signal to, inputs to computing machine or similar control system 2 then, and computing machine or control system 2 are controlled printer 3 as requested and printed Monitoring Data according to specific program.Because above-mentioned monitoring system is comparatively huge, and costs an arm and a leg, for a multiple spot, complicated monitoring is necessary, but for some simple monitorings, it is very uneconomic adopting said system.

The present invention is an analog signal printing interface, can link to each other with present various general digital printers, can realize the manual printing of analog electrical signal after linking to each other by the print control key among Fig. 25, also can be by the print control signal line 7 among Fig. 2, the realization that links to each other with other control system is printed automatically.It controls the A/D change-over circuit with single-chip microcomputer or general cpu chip, and the control signal that analog electrical signal is converted to printer directly drives the printer prints data.Analog signal printing interface as shown in Figure 2, analog input interface 1 promptly can be a single channel, also can be optional multi-channel analog signal input port, it links to each other with A/D converter 2 with channel switch, inputs to control circuit 3 after converting the analog electrical signal of dedicated tunnel to digital signal.Control circuit 3 is by single-chip microcomputer or cpu chip, EPROM chip or rom chip (can also have data-carrier store RAM chip in case of necessity) and control circuit are formed, its control program is solidificated in EPROM chip or the rom chip, when operating personnel press print control key 5 or print control signal line 7 and transmit outside print signal, control circuit 3 begins the analog electrical signal of dedicated tunnel is carried out the A/D conversion, and with the printer model of switching signal according to appointment, further convert the print signal of printing function identification to, and the control printer prints.Parameter setting switch 6 is used for setting the type channel number, data layout and printer model.Because analog signal printing interface only solves the transformation of analog electrical signal to the print signal of printing function identification, function singleness, therefore volume is little, simple in structure, promptly can making independently, complete machine links to each other with present universal printer, finish the print job of analog electrical signal, can make one with printer again, become an analog signal printer.

The present invention is an analog signal printer, can directly import analog electrical signal, promptly can manually print, and also can print by the print start signal line traffic control.Structure as shown in Figure 3, it is by simulating signal input control mouth 1, printer main body 2 and print control key 3 are formed, simulating signal input control mouthful 1 one side receives analog electrical signal, also have a print control signal line to be used for importing outside print signal in addition, with the automatic control that realizes that data are printed.Among Fig. 32 is printer main body, contains paper advance mechanism, and control circuit and mechanical transmission mechanism are printed by print drive mechanism.Among Fig. 33 is print control key, and operating personnel realize manual printing function and control paper feed or the like by this key.

Claims (2)

1, a kind of analog signal printing interface is characterized in that, this interface converts analog electrical signal to the print signal of printing function identification, directly drive the printer prints data, analog electrical signal can be that single channel also can be a hyperchannel, and when hyperchannel, its input channel can be selected arbitrarily; Interface is provided with selector switch, is used for selecting input channel, the specifications and models of print format and printer, and the printing of printer starts promptly can be handled by print control key, also can control by the outside print signal of print control signal line input.

2, a kind of analog signal printer of making according to claim 1, it is characterized in that, this printer is directly imported analog electrical signal and print signal by simulating signal input control mouth, the printing of printer starts promptly can be handled by print control key, also can control by the outside print signal of print control signal line input, print format and input channel are selected to be set by state selecting switch, and print control key also has the paper feed control function of present universal printer.
