Abstract
The utility model relates to a membrane type household gas meter, especially is a digital display RF card type gas meter. The device is characterized in that an upper shell panel back of the gas meter is pasted with arousal using magnetic induction element whose output connects with a control unit to be used as a starting arousal signal to form arousal switch. The bonding PF retaining clip layer is provided with a magnetic tablet. The membrane type household gas meter of the utility model starts magnetic induction element pasted at the back of the shell panel by the magnetic tablet arranged in the PF card when PF card is near the upper shell panel of the gas meter, and the signal is sent to the control unit to arouse system, and then the data exchange starts, with the exerted starting switch cancelled, and the disadvantages that exerted vulnerable component of the current gas meter, easy destruction and short service life overcome.
Description
Technical field: the utility model relates to a kind of membrane type domestic gas meter, particularly digital display RF cassette gas meter, flow meter.
Background technology: along with epoch and development of science and technology, the membrane type domestic gas meter has passed through from the mechanical character wheel formula to digital display type, the RF cassette evolution from the IC-card formula to less radio-frequency.The performance of each side such as precision, reliability, anti-tampering, anti-surreptitiously gas etc. and function all have great raising, particularly RF card membrane type domestic gas meter is especially because it adopts less radio-frequency to carry out exchanges data, cancel the IC-card socket in the IC-card membrane type domestic gas meter, eliminated the deficiency that IC-card formula socket exposes sensitive for damages.But also have some defectives, blocking, when showing exchanges data, just can carry out after all will pushing the start button on the panel as existing RF card membrane type domestic gas meter, automaticity is not high, does not reach contactless completely; Because start button all exposes, be damaged easily in addition, serviceable life is not long yet.
Summary of the invention: the purpose of this utility model is to provide a kind of contactless fully for the deficiency that overcomes existing membrane type domestic gas meter, does not have and exposes consumable accessory, the membrane type domestic gas meter of longer service life.
Membrane type domestic gas meter of the present utility model comprises the membrane type base table equally, upper shell, be arranged on control module and display unit and flow sensing assembly and attached RF card of joining in the upper shell inner chamber, the flow sensing assembly comprises rotary valve, gear, link rod and be fixed in the magnet steel frame of gear shaft end, be fixed with magnet steel on the magnet steel frame, link rod connection gear axle and rotary valve constitute the rotation interlock, contiguous magnet steel rotary motion trace place is provided with the counting magnetic induction part, it is characterized in that: the upper shell panel rear side of described gas meter, flow meter has been sticked to wake up and has used magnetic induction part, and the output of described magnetic induction part is connected with control module as starting wake-up signal formation wake-up switch; Be provided with magnetic piece in the attached RF clip layer of joining.
Adopt the membrane type domestic gas meter of such scheme, when the upper shell panel of RF card near gas meter, flow meter, start the magnetic strength element that watchcase panel rear side is sticked by the magnetic piece that is arranged in the RF card, and thereby this signal delivered to waken system in the control module, begin to carry out exchanges data, therefore cancelled the start button that exposes, having overcome existing gas meter, flow meter has the consumable accessory of exposing, be damaged the drawback that serviceable life is not long yet easily.
The utility model is described in further detail below in conjunction with accompanying drawing, and provide embodiment.
