Abstract
The utility model discloses an electronic gas meter. The electronic gas meter comprises a microprocessor, a power supply circuit and a double-interface storage chip, wherein the chip comprises a serial interface and a wireless radiofrequency interface, and is connected with the microprocessor through the serial interface; the power supply port of the chip is connected with the power supply circuit. The double-interface storage chip provided with the serial interface and the wireless radiofrequency interface is adopted. When a power supply portion or a display interface portion of the gas meter fails, the storage chip can be separated from a main MCU (Microprogrammed Control Unit) and a main power supply circuit, wireless card-reading equipment is supplied with power separately in a wireless manner through an RF (Radiofrequency channel), and data inside the storage chip are read out, thereby ensuring that history metering data of the meter can still be read when the gas meter fails, the loss of a gas company is reduced effectively, and complex operation for restoring field data is reduced.
Description
Technical field
The utility model relates to a kind of gas meter, flow meter, particularly a kind of electronic gas table.
Background technology
Current existing electronic type gas meter, uses dry cell power supply conventionally, and LCDs is as master data display interface, and the storage that table counts generally adopts the external eeprom memory of I2C interface or uses the storer that in circuit, main MCU chip carries.In this design, once the contact corrosion of battery case or LCDs occur because the reasons such as high temperature, low temperature, physics compressing cannot show, often do not have effective means can read the inner continuous data of table meter, ability sense data after needing Chai Biaofan factory and office to manage, complicated operation, not too adapts to large-scale promotion and uses.
Utility model content
The purpose of this utility model is to provide a kind of electronic gas table that table counts that still can read in the time of gas meter, flow meter power-off or fault.
This electronic gas table that the utility model provides, comprises microprocessor, power circuit, and this gas meter, flow meter also comprises double nip storage chip, and this chip comprises 1 serial line interface and 1 wireless radio interface; This chip is connected with microprocessor by serial line interface, and its power port is connected with described power circuit.
The power supply of described double nip storage chip is provided by the antenna of this wireless card reading equipment in the time of itself and wireless card reading device talk.Described wireless radio interface and the wireless connections of wireless card reading equipment.Described double nip storage chip adopts the storage chip that model is M24LR.
The utility model has adopted a kind of double nip storage chip with serial line interface and wireless radio interface.In the time that the power pack of gas meter, flow meter or display interface part break down, this storage chip can depart from main MCU and main feed circuit, separately by wireless card reading equipment via RF passage wireless power, and by the data reading of storage chip inside, thereby guarantee, in the time that table meter breaks down, still can read the historical continuous data of table meter, effectively reduce the loss of gas company,, reduced the complex operations of restoring scene data.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises microprocessor, power circuit, battery power detection circuit, button inputting circuits, valve controling circuit, pulse-detecting circuit, magnetic interference testing circuit, pulse detection plate, LCD LCDs, datel circuit and double nip storage chip.Above-mentioned other each functional circuits except power circuit are by microprocessor control; Power circuit provides power supply by battery.
Double nip storage chip comprises 1 serial line interface and 1 wireless radio interface; This chip is connected with microprocessor by serial line interface, and its power port is connected with power circuit, and this chip is responsible for the service data of preservation table meter.
When normal work, microcontroller of the present utility model by serial line interface will show to count service data (as gas meter, flow meter gas consumption continuous data, user purchase, with gas record data etc.) be kept in double nip storage chip; The utility model can pass through datel circuit (as IC-card read/write circuit or wireless communication line) and gas company's Background communication, service data of the present utility model is offered to the background system of gas company, for gas company's metering and billing.
When table meter breaks down, power circuit cannot normal power supply or micro controller system move when undesired, gas meter, flow meter cannot normally pass to gas company by datel circuit by normal gas meter, flow meter service data, the utility model can be in the situation that not taking gas meter, flow meter structure apart, pass through the direct and double nip storage chip communication via RFID radio channel of wireless card reading equipment, the service data of reading gas meter, flow meter by the technician of gas company; Now, the power supply of double nip storage chip is also provided by the antenna of wireless card reading equipment, count other functional modules with whole table and whether can normally work irrelevantly, also do not affect reading of gas meter, flow meter service data even if the electric power system of the whole electronic module of table meter breaks down.
The utility model only needs double nip storage chip and antenna part normally just can very simply recover to read field data.Therefore, the ebctronic reliability designing requirement of the utility model his-and-hers watches meter is very low, and the recovery of data is read also very simple, and the technician of Zhi Xu gas company carries a wireless card reading equipment just can complete the on-the-spot read work of showing meter service data.
