Design And Implementation Of Collected Safe Based On ARM

There are many big places of cash transactions at home and abroad, such as largesupermarkets, department stores, large-scale toll stations, hotels, hospitals etc. These placesspend a lot of manpower and material resources to count, check and store cash. They involvea large number of cash transactions, so it will inevitably lead to low efficiency and cash lossproblems. Taking the economic and performance into consideration, the collected safety ofthis paper design combines with the advantages of ATM and POS, it has the advantages oflow cost, miniaturization, high performance, high reliability and convenient operation, etc. Italso has the functions of receiving notes, checking money, depositing, printing receipts andweb management and so on. It solves the problems of cash transactions in the market.The ARM structure has strong control function. It plays an important role in theembedded system. The combination of ARM processor and embedded Linux becomes moreand more closely, and it is widely used in the embedded fields. This paper researches theembedded collected safe which based on ARM and Linux operating system. Firstly, accordingto the function requirement of collected safe, this paper introduces the overall design scheme.And then, according to the total design scheme are introduced gradually, this paper introducesthe implementation of the collected safe’s hardware and software. The design of the softwareand hardware adopts the design method of modular. It makes relatively independent amongmodules and it is convenient for people to maintain and improve the system.Repeated tests of hardware and software proved data accuracy of the bill receiving andprinting a receipt. The database which is browsed through the web also proved the real time ofthe system. In brief, the whole system has a high security and stability, it basically meet thecustomer’s demand. At present, it has already been put into small batch production.
