Abstract
The utility model belongs to the class of a card reader device, which is specifically a card reader device for the cost allocation meter. The utility model comprises a cost allocation meter and an encryption card. The utility model is characterized in that a magnetic sensor is installed in the induction area of the contact card reading interface of the cost allocation meter; a mini-type permanent magnet is embedded in the corresponding place of the encryption card; one end of the magnetic sensor is connected with the ground; the other end of the magnetic sensor is connected with the terminal pin of the CPU; the anode of the card reader interface is connected with the port of the CPU; the cathode of the card reader interface is connected with the ground. When the magnetic sensor of the utility model senses the magnetic field, the utility model emits the electrical level variation pulse which is sent to the break-off pin of the CPU to generate the break-off request of the card reader; then the CPU starts a card reading process; after the card reading process, the CPU can enter into the dormant status or the low power consumption status again. The card reader device can be widely applied in the cost allocation and encryption system of the prepaid water meter, the prepaid electric meter and the prepaid gas meter, which requires the low power consumption and the outdoor application.
Description
Technical field
The utility model belongs to charging reader device class, specifically is a kind of taximeter reader device.
Background technology
The type of existing encrypted card comprises: TM card, ID card, IC-card etc., and the card reader of contact-carryings such as known TM card, IC-card, in order to inquire the contact of card in real time, its contact all is to be with galvanicly, therefore is not suitable for using under outdoor and moist environment.And contactless card reader such as ID card then will be launched request signal in real time, are not suitable in the application scenario that requires low-power consumption.The prepay water meter that uses, pre-paying kilowatt-hour meter, prepayment diaphragm gas meter etc. require the taximeter that low-power consumption and outdoor utility require at present, and existing reader device is not suitable for.
Summary of the invention
The purpose of this utility model is the deficiency at existing technology, and providing does not need the contact charged and can launch request signal in real time, can adapt to the taximeter reader device of low-power consumption requirement and outdoor utility environment.
The technical solution of the utility model is as follows:
A kind of taximeter reader device, comprise taximeter, encrypted card, it is characterized in that: the contact Card Reader mouth induction zone at taximeter is installed a magnetometric sensor, embed a minitype permanent-magnet in the relevant position of encrypted card, magnetometric sensor one end ground connection, one end links to each other with the terminal leads of CPU, and Card Reader mouth positive pole links to each other minus earth with the port of CPU.
The position that the utility model permanent magnet embeds generally will make and allow permanent magnet near also driving magnetometric sensor when Card Reader.
The utility model magnetometric sensor can adopt tongue tube or low-power consumption Hall element.
The utility model will send a level change pulse when magnetometric sensor is sensed magnetic field, this level change pulse is sent to the terminal leads of CPU (microcontroller), produce the Card Reader interrupt request, CPU just begins the Card Reader process one time, after finishing Card Reader process, CPU can reenter dormancy or low power consumpting state.Have only encrypted card once more near and when triggering Magnetic Sensor, just carry out the Card Reader operation again.Magnetometric sensor is sealed in device inside, is isolated from the outside, and therefore is not subjected to external environment influence, can work under outdoor and wet environment, has reduced power consumption simultaneously.
The utility model has overcome that general reader device can not be worked and the problem of power consumption under outdoor and wet environment, can be widely used in charging and encryption system that prepay water meter, pre-paying kilowatt-hour meter, prepayment diaphragm gas meter etc. require low-power consumption and outdoor utility to require.
