Electronic computer can be used IBM386.The speed of the transmission of electronic computer, reception data is 1200,2400,4800,9600 baud rates.The data broadcasting card was realized with being connected by the electronic computer bus of electronic computer.Receiving software and transmission software all exist in the electronic computer.The data broadcasting jig has intelligence, can carry out encryption to the data of transmission or reception.The verification correction process, Ben Ka can send and receive remote information, and by the control receiving system work of this guidance command or quit work.Electronic computer uses when originally sticking into capable work, does not influence electronic computer and carries out other work.
The present invention can illustrate its application by following two examples:
Example 1, enterprise has every day or every month a collection of reconciliation and the interest inventory need in time obtain, and traditional method is that statement or interest bill are fetched by the bank that regularly sends someone of enterprise.This method major defect is that efficient is low, real-time is poor, makes troubles for factory director and manager's management and decision-making in real time, can utilize the computer receiving, storing and managing to carry out the reconciliation business now.By method of the present invention, bank imports user's bill and interest inventory in the electronic computer every day or every month, send by FM radio, and each user can receive the various documents of this enterprise in the computer of oneself, computer can be handled and other irrelevant business of this receiving system simultaneously, is a tractor serves several purposes.Storage, inquiry, printing function are provided.This system has been arranged, and the user not only can see nearest reconciliation information, can also inquire about the historical data that stores, and makes the user financially realize computer control.This method is applied to banking, the security reliability height, and all data all adopt ciphertext to transmit, and non-validated user can't receive correct data.
Example 2, foreign trade unit and for example, it needs a large amount of foreign demand information, opens up the commodity business in those fields so that determine our unit; Our unit will carry out organization work of which kind of commodity or the like.So, this foreign trade unit only need purchase the data broadcasting card in the receiving system of this device, fm broadcast receiver, add the former computer that had, the demand for commodity information of the rating parties concerned periodically just, or computer is opened and to be carried out its original business every day, at will when all can inquire about the demand information of the commodity that our unit is concerned about.Here it is, and this method one will be put a tractor serves several purposes.
The main points of the inventive method are:
One, will need the various information that sends, be input in the electronic computer,, deliver to the FM broadcasting encoder, deliver to day aerial again through frequency-modulated broadcast transmitter through the data broadcasting card.
Two, FM radio sends remote information, can romote controlled receiving system work, and promptly can allow a certain receiving system stop reception work, also can allow a certain receiving system that has stopped receiving function recover receiving function.
Three, FM radio receives data, literal and graphical information, is the information via data broadcasting card that will receive, and information is deposited in the electronic computer, so that allow user search, inquiry etc.
Four, receiving system has the hardware capability of AM/BAM.Make user's computer a tractor serves several purposes.Promptly can receive data, literal and graphical information that FM radio sends, can allow computer do other work simultaneously again.
The inventive method is that wireless communication technology, electronic circuit technology, electronic computer are gathered together, and is used for FM broadcasting, so that transmit general information, as: finance, traffic, cooperation or the like; Specific information, as: bank's reconciliation, customs information or the like, go up the needs in types of applications field to be adapted to society.It contains much information, and wide application all can't be compared with it with in the past newpapers and periodicals, magazine, wire communication.
Utilize fm radio transmission of information, service range is wide, and small investment contains much information.Particularly make broadcasting equipment bring into play multinomial broadcasting service, for community service increases fresh content.
