摘要：This article proposes a scheme which realizes the remote update of the dispersed client program through GPRS network by making use of the IAP (In Application Programming) function of the LPC2214 microprocessor. The scheme introduces the IAP function of LPC2214 and the method of using IAP interface, designs a communications protocol, describes and explains the data form of the application layer, and finally describes in detail the realization of the program design, and gives the flow chart of the program. The scheme proposed in this article takes advantage of the IAP function of the LPC2214 processor in the client and the GPRS radio communications technology. Research proves that this scheme is effective to solve the remote update problem of dispersed taxi client
