Abstract
The utility model discloses a built-in tax control module, which comprises a central processor, a USB (universal serial bus) interface module, a real-time clock, a system information memory, a power supply detector, a backup battery, a tax control memory, a master control board interface, a user card interface and a tax control card interface which are respectively connected with the central processor; and the master control board interface is further detachably connected with a master control board of a tax control billing machine. According to the built-in tax control module, since the master control board interface which is detachably connected with the master control board of the tax control billing machine is arranged, when a fault of the tax control billing machine occurs, the built-in tax control module can be dismantled from the master control board and applied into another master control board of another tax control billing machine, the application scope is wide, and the requirement on using of a user is satisfied.
Description
Technical field
The utility model relates to the tax-controlled electronic product technical field, relates in particular to built-in tax-controlling module.
Background technology
The primary structure of existing built-in tax-controlling module is a central processing unit, and it is mainly used to realize system management function and the tax control function of invoice-making machine for tax control.During use, its master control borad general and invoice-making machine for tax control in invoice-making machine for tax control is fixedly linked.In case invoice-making machine for tax control breaks down in the time of can't using, built-in tax-controlling module can not take apart from master control borad and be applied on other invoice-making machine for tax control, and usable range is relatively limited to.
The utility model content
Technical problem to be solved in the utility model provides a kind of built-in tax-controlling module, and it also can take apart from master control borad on the master control borad of the invoice-making machine for tax control that is applied to again other when invoice-making machine for tax control breaks down, and usable range is very extensive.
In order to solve the problems of the technologies described above, the technical scheme content that the utility model adopts is specific as follows:
Built-in tax-controlling module, it comprises central processing unit and the usb interface module that links to each other with described central processing unit respectively, real-time clock, system info storage, Power supply detector, backup battery, tax-controlling memory, master control borad interface, subscriber card interface and tax-controlling card interface; Also the removably connect master control borad of invoice-making machine for tax control of described master control borad interface.
Preferably, central processing unit is that model is the processor of SM5964.
Preferably, described tax-controlling memory is that model is the storer of AT45DB161.
Preferably, described real-time clock is that model is the clock chip of DS1302.
Preferably, described Power supply detector is that model is the Power supply detector of S80840.
Preferably, described subscriber card interface is the IC-card interface.
Preferably, described tax-controlling card interface is the IC-card interface.
Preferably, described master control borad interface is serial line interface.
Preferably, described serial line interface is comprised of the socket of two 16PIN.
Compared with prior art, the utility model has produced following beneficial effect:
The removably connect master control borad interface of invoice-making machine for tax control master control borad of built-in tax-controlling module being provided with of the present utility model, when breaking down, invoice-making machine for tax control also built-in tax-controlling module can be taken apart from master control borad on the master control borad of the invoice-making machine for tax control that is applied to again other, usable range is very extensive, has satisfied user's user demand.
Description of drawings
The utility model will be further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is the more preferably structural representation of embodiment of built-in tax-controlling module of the present utility model.
Embodiment
As shown in Figure 1, built-in tax-controlling module of the present utility model, it comprises central processing unit and the usb interface module that links to each other with described central processing unit respectively, real-time clock, system info storage, Power supply detector, backup battery, tax-controlling memory, master control borad interface, subscriber card interface and tax-controlling card interface; Also the removably connect master control borad of invoice-making machine for tax control of described master control borad interface.
Particularly, central processing unit is that model is the processor of SM5964.
Particularly, described tax-controlling memory is that model is the storer of AT45DB161.
Particularly, described real-time clock is that model is the clock chip of DS1302.
Particularly, described Power supply detector is that model is the Power supply detector of S80840.
Particularly, described subscriber card interface is the IC-card interface.
Particularly, described tax-controlling card interface is the IC-card interface.
