Abstract

The utility model relates to a card & table data comparing instrument. The instrument applies to the card-type bill prepaying water meter maintenance of the water supply industry, pertaining to an intelligent measuring apparatus for the area of electronic information applied technology. The utility model is with CPU module, user card socket and measuring card socket, during operation, the user card and measuring card are to be inserted into the data port, 2 groups of data is to be processed by the CPU module and indicated by user card and measuring card indicating module separately. Through comparison, one can easily find out where the malfunction of the card type bill prepaying water meter is. With the help of the relative software, one can check at will all the information in the card, by resource information switching button, one can check the detail and overall information, the contents indicated are: card number, total water volume consumed, the last purchased water volume, number of water purchasing. The utility model is of reliable performance, and enables one compare the resource information directly, small in size, and provides the maintenance worker with convenience and efficiency.

Description

Card table data comparison instrument

Technical field

The utility model relates to a kind of card table data comparison instrument, is applicable to the maintenance of water supply industry card type prepayment water meter, a kind of intelligent inspection apparatus of safeguarding, belongs to the electronic information applied technical field.

Background technology

The aggravation of the quickening of Chinese Urbanization paces and shortage of water resources contradiction is used widely card type prepayment water meter in the urban water supply metering.Along with popularizing of this novel measuring products, the maintenance, repair amount of card water meter constantly increases.But because card water meter relates to multinomial technical fields such as machinery, electronics, computing machine, information Control, present maintenance to the Ka Biaobiao tool, generally all adopt and open housing, parts such as base table, data transducer, control circuit are detected one by one, just can find out crux, fix a breakdown program complexity, time-consuming

Summary of the invention

The purpose of this utility model is at there not being the dedicated test instrument at present when the maintenance, repair card type prepayment water meter, thereby generally all adopt and open housing, parts such as base table, data transducer, control circuit are detected one by one, just can find out the deficiency of crux, be provided under the situation of not opening table tool shell, but a kind of card table data comparison instrument that his-and-hers watches tool fault is effectively judged.

The purpose of this utility model is achieved through the following technical solutions, a kind of card table data comparison instrument, it is characterized in that described comparison instrument is by housing, CPU control module and peripheral circuit in the housing, voltage source, the subscriber card display module, check the card display module and be fixed on subscriber card deck on the housing, check the card deck, resource information switching button and subscriber card display module, check that the liquid crystal display that card display module output terminal connects respectively constitutes, the subscriber card deck, check that the card deck connects the data exchange interface of CPU control module, the subscriber card display module, check that the card display module connects the subscriber card video data interface of CPU control module respectively, check card video data interface, the resource information switching button connects the trigger interface of CPU control module.

The utility model is by being provided with CPU control module, subscriber card deck, checking the card deck, subscriber card, inspection card insert in the data-interface respectively during use, two groups of data are handled by the CPU control module that is provided with, demonstrate two groups of data respectively by subscriber card, inspection card display module, by comparing, be easy to judge the guilty culprit of card type prepayment water meter, in order to safeguarding and maintenance.

Under the support of related software, two groups of data can be checked all information in the card at any time when comparing, and by the resource information switching button, can check up and down, and displaying contents is respectively that card number, accumulated water volume, the last time are purchased the water yield, purchased the waterside number.The utility model dependable performance is can be intuitively little to resource information comparison, volume, provide condition effectively easily for the maintenance personal.

Description of drawings

Fig. 1 is the utility model circuit theory diagrams and block scheme;

Fig. 2 is a CPU control module wiring schematic diagram in the utility model;

Among the figure, 1 battery, 2CPU control module, 3 display modules, 4 display modules, 5 subscriber card decks, 6 are checked card deck, 7 buttons, 8 buttons, 9 liquid crystal displays, 10 liquid crystal displays.

Embodiment

Further specify the utility model in conjunction with the accompanying drawings and embodiments, the utility model is by housing, CPU control module 2 and peripheral circuit, battery 1, subscriber card deck 5, subscriber card display module 3, check card deck 6, check card display module 4, subscriber card display module 3, check the liquid crystal display 9 that card display module 4 output terminals connect respectively, 10 and the resource information switching button constitute, CPU control module 2 adopts plc16f72l/so, subscriber card deck 5, check that card deck 6 meets the data exchange interface (SDATA of CPU control module 2, SCLKICCLK, POWER, GND, ICSW, ICDATA), subscriber card display module 3, check that card display module 4 connects the subscriber card video data interface of CPU control module 2 respectively, check card video data interface (LCDDATA, DATAS, CS, ICSW, POWER, GND), the resource information switching button comprises page-turning button 7, following page-turning button 8, last page-turning button 7, following page-turning button 8 meets the trigger interface (SWCIOSE of CPU control module 2, SWOPEN, GND), to check card display module 4, subscriber card display module 3 output terminals connect liquid crystal display 9 respectively, 10, subscriber card deck 5, check card deck 6 and last page-turning button 7, following page-turning button 8 is fixed on the housing, subscriber card display module 3, check that card display module 4 all adopts 8BIT128LCD, during use, to check that card inserts water meter inspection card deck 6, show good, expression has copied the water meter store data inside to be checked in the card; Subscriber card and inspection card are inserted respectively in the corresponding deck of comparison instrument; Microprocessor in the CPU control module 2 sends query statement to read-write equipment, carries out data query simultaneously and checks; Can show card number, accumulated water volume, this water yield, purchase the waterside number with the corresponding liquid crystal display of subscriber card; Can show card number, accumulated water volume, this water yield, purchase waterside number, surplus water with checking the corresponding liquid crystal display of card; Table tool fault judgement is made in demonstration according to liquid crystal display, carries out effective maintenance, repair.
