Abstract
The invention provides a collector communication multiplexing serial port automatic switching device which comprises a collector single chip microcomputer control module, a multicircuit switch module, a timer module, and an infrared receiving tube; an output terminal of the infrared receiving tube is connected with an interruption pin of the collector single chip microcomputer control module; the timer module and the multicircuit switch module are connected with the collector single chip microcomputer control module; a first switch of the multicircuit switch module is connected with an infrared communication channel of the collector; a second switch of the multicircuit switch module is connected with a carrier wave communication channel of the collector. When the infrared receiving tube receives an infrared signal, the collector single chip microcomputer control module responds to an interruption request; a serial port of the collector automatically switches to the infrared communication channel, and then automatically switches to the carrier wave communication channel when set time is reached; therefore, automatic switch between the infrared and carrier wave communication multiplexing serial ports of the collector is realized; and the device is not only simple in structure, and convenient for operation, but also easy to realize, and high in working efficiency.
Description
Technical field
The present invention relates to a kind of communication modes automatic switching control equipment, specifically, related to a kind of collector communication multiplexing serial port automatic switching control equipment for the low pressure carrier wave kilowatt meter reading-out system.
Background technology
Checking meter at existing low pressure carrier wave is, collector connects the user electric energy meter and carries out communication by low pressure carrier wave and concentrator by 485 buses, and main website then carries out communication by GPRS, telephone network etc. with concentrator.In existing technology, can check meter at the scene of realizing by the infrared communication function of collector, but the collector in the prior art, the multiplexing microcontroller serial port of its infrared and carrier communication carries out passage by 4052 multicircuit switches and switches.Normal condition is carrier channel, when the needs infrared communication, then be manually to click the infrared communication button, passage is switched to infrared mode, through behind certain timing, automatically switch back to the carrier communication passage, this mode has increased the labour intensity that site infrare is checked meter undoubtedly, has reduced the work efficiency that site infrare is checked meter.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, thereby the collector communication multiplexing serial port automatic switching control equipment of a kind of design science, simple in structure, easy to operate, high efficiency is provided.
To achieve these goals, the technical solution adopted in the present invention is: a kind of communication multiplexing serial port automatic switching control equipment, a kind of collector communication multiplexing serial port automatic switching control equipment, it comprises the collector single chip control module, the multicircuit switch module that is connected with described collector single chip control module, the timer module, infrared receiving tube, the output terminal of described infrared receiving tube connect the interrupt pin of described collector single chip control module so that described infrared receiving tube can send interrupt request singal to described collector single chip control module when receiving infrared signal; Thereby described timer module connects described collector single chip control module to provide timing function to limit the interrupt response time of described collector single chip control module; The first switch of described multicircuit switch module connects the infrared communication passage of collector, the second switch of described multicircuit switch module connects the carrier communication passage of collector, with by described collector single chip control module to the interrupt response of described infrared receiving tube automatically switch infrared communication passage and the carrier communication passage of collector communication multiplexing serial port.
The relative prior art of the present invention has outstanding substantive distinguishing features and marked improvement, and specifically, the present invention has realized the automatic switchover of collector infrared communication and carrier communication multiplexing serial port.When hot outer receiving tube receives infrared signal, collector single chip control module response interrupt request, serial port automatic switching is to the infrared communication passage, timing was after the past, automatically switch back to the carrier communication passage, thereby improved the work efficiency that site infrare is checked meter, reduced the labour intensity that site infrare is checked meter; The present invention can also be widely used in need to the multiplexing relevant microcontroller serial port communication occasion of infrared communication in, structure arranges simply, is easy to realize.

Embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
As shown in Figure 1, a kind of collector communication multiplexing serial port automatic switching control equipment, it comprises collector single chip control module, the multicircuit switch module, timer module, the infrared receiving tube that are connected with described collector single chip control module.
The output terminal of described infrared receiving tube connects the interrupt pin of described collector single chip control module, described timer module connects described collector single chip control module, the first switch of described multicircuit switch module connects the infrared communication passage of collector, the second switch of described multicircuit switch module connects the carrier communication passage of collector, during normal condition, the serial ports on-state of described collector single chip control module is the carrier communication passage of collector.
When described infrared receiving tube receives infrared signal, send interrupt request singal to described collector single chip control module, described collector single chip control module response interrupt request singal, the switch of described multicircuit switch module switches to the first switch, the infrared communication passage of collector is connected the serial ports of described collector single chip control module, carry out the infrared communication function of collector, thereby finish the work of checking meter; In the time of described collector single chip control module response interrupt request singal, the timing function of described timer module starts, thereby limit the interrupt response time of described collector single chip control module, time is regularly set by the required time of checking meter, can be set to two minutes regularly, when regularly time then, described collector single chip control module finishes the response to this interruption, the switch of described multicircuit switch module switches to the second switch, the serial ports on-state of described collector single chip control module is switched return load ripple communication channel, thereby has finished the infrared communication passage of collector and the automatic switching function of carrier communication passage.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present invention; And not breaking away from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
