Description of drawings
Fig. 1 is the structure principle chart of the digital electricity meter tester that provides of the utility model embodiment.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 shows the structural principle of the handheld digital electric energy meter tester that the utility model embodiment provides, and for the ease of explanation, only shows the part relevant with the utility model embodiment.
Handheld digital electric energy meter tester can be widely used in the on-the-spot test to digital electricity meter, comprises power management plate 1, industrial computer 2, touches Control Component 3, display screen 4, digital signal panel 5.
As an embodiment of the utility model, in order to make the digital electricity meter tester be easy to carry, give the power management plate 1 power supply through lithium ion battery, lithium ion battery output electric energy is to power management plate 1, and power management plate 1 provides the constant voltage signal of 5V.
When concrete the realization, lithium ion battery adopts the 11.1V battery of 2200MAH, can guarantee that power supply is more than 2 hours.The user can connect with the mains with power supply adaptor and work on after the lithium ion battery electric weight uses up.Because the inner electric power system of digital electricity meter tester mainly is the power supply with 5V, so power management plate 1 is integrated with power transfer module and power protection module, carries out power source conversion and power protection.
As an embodiment of the utility model, power management plate 1 power source conversion has adopted 2 powerful power transfer module, the voltage transitions of 11.1V is become the voltage signal of the 5V that can the confession system uses.
The power protection module is in time cut off battery supply, to guarantee the life-span of lithium ion battery at the low electric weight of lithium ion battery under the perhaps oversaturated situation.
Industrial computer 2 is connected with digital signal panel 5 with touch Control Component 2, display screen 4 respectively.Industrial computer 2 is mainly used in the exploitation man-machine interface, and the completion instruction is assigning of order perhaps, and the function that data communication and result show is passed through RS232 serial ports exchange command and data with digital signal panel 5.
Touching Control Component 3 mainly is to be used for the user to operate through 4 pairs of testers of display screen, substitutes the function of input medias such as mouse.
Display screen 4 adopts LCDs, and display digit signal-processing board 5 carries out relevant information such as the electric current and voltage, electric energy error after the data parsing and gives user's reference.
Comprise optical transceiver 51, ethernet controller 52, digital signal processor (Digital Signal Processor, DSP) 53 in the digital signal panel 5.
Ethernet controller 52 can adopt fast Ethernet controller chip AX88796; Its inside is integrated with the adaptive physical layer transceiver of 10/100Mb/s; And the SRAM of 8K * 16, carry out 10Mb/s and 100Mb/s Ethernet control function based on the IEEE802.3/IEEE802.3U local area network standard.
Communicate by letter through data/address line between ethernet controller 52 and the digital signal processor 53.
Between optical transceiver 51 and the ethernet controller 52 based on the IEC61850 protocol communication.
