Description
Technical field
The present invention relates to a kind of electric energy meter, especially based on the local control electric energy meter that takes of the telemanagement of double-interface smart card (RFID-SIM card).
Background technology
The electric energy meter management of present stage realizes through 485 communications, infrared communication, power line carrier, PLC, but under a lot of complex environments, these communication modes can not be realized the management to electric energy meter.The present stage expense control of electric energy meter mainly realizes through the contact intellective IC card; Open IC-card mouth has brought a lot of potential hidden danger; And the management of electric energy meter realizes through two modules with the expense control; The structure of electric energy meter also becomes more and more compacter along with the increase of module, makes the many necessary requirement of electric energy meter industry standard the inside implement very difficulty.And that RFID-SIM is stuck on the volume is the same with common SIM, and the functionality mobile communication the same with common SIM promptly arranged on function, can carry out wireless near field communication through RFID (RF identification) chip that is integrated in the card the inside again.
Summary of the invention
The purpose of this invention is to provide a kind of electric energy meter that can realize contactless local expense control through wireless remote management.
The local control electric energy meter that takes of a kind of telemanagement based on double-interface smart card; Comprise microprocessor; Its special feature is; Also comprise the wireless communicaltion module access that is connected with this microprocessor, thereby and the wireless communication module that is connected with this interface realize wireless remote management and contactless local expense control function; Also comprise the power-supply system that is connected with this microprocessor, this power-supply system adopts the AC/DC Switching Power Supply, the input termination civil power of this AC/DC Switching Power Supply and export the termination microprocessor.
Wherein wireless communication module comprises RFID-SIM cartoon letters module and GSM, GPRS or cdma network communication module.
Technology of the present invention compared with prior art, the one, realize one card for multiple uses promptly structurally having reduced volume, on function, realized innovation again; The 2nd, can realize contactless local expense control, the user can realize the local at any time control that takes according to the demand of oneself; The 3rd, to check meter conveniently, power supply department need not the user power utilization scene and carries out loaded down with trivial details checking meter, and only needs just can realize checking meter through long distance wireless; The 4th, simple to operate, multiple functional, electric energy meter has inquiry button, can inquire about the data in the ammeter easily, functions such as electric energy metrical, logout, warning that electric energy meter is integrated; The 5th, safe and reliable, electric energy meter is totally enclosed, the hidden danger of having avoided the open bayonet socket of intellective IC card to be caused.
Description of drawings
Accompanying drawing 1 is the theory diagram of electric energy meter of the present invention.
Embodiment
Come the present invention is done further detailed explanation below in conjunction with accompanying drawing:
As shown in Figure 1; The local control electric energy meter that takes of a kind of telemanagement based on double-interface smart card; Comprise microprocessor; Also comprise the wireless communicaltion module access that is connected with this microprocessor, thus and the wireless communication module that is connected with this interface realization wireless remote management and contactless local expense control function.Wherein wireless communication module comprises contactless RFID-SIM cartoon letters module and GSM, GPRS or cdma network communication module.
As shown in Figure 1; The invention discloses a kind of wireless remote management of all-sealed design, contactless this locality expense control electric energy meter; This electric energy meter mainly comprises several partial circuits such as special high-accuracy electric energy computation chip, high-performance embedded microprocessor, dedicated system clock, power management module, infrared communication interface, wireless module communication interface, RFID-SIM cartoon letters module, LCD display, Mass Digital Storage System, breaker tripping and closing relay; Local communication indicator is arranged on the electric energy meter; Can show the near-field communication state, also have teledata to receive designator in addition, can show the telemanagement of power supply administration electric energy meter.
The management server of power supply administration can carry out the parameter setting to electric energy meter through remote wireless network, comprises the setting of alarm threshold setting, a recharge amount; Can also carry out operations such as copy reading through remote wireless network to data, electric energy meter also can initiatively report the task and the abnormal conditions of customization.Local contactless expense control function then can realize the function supplement with money at any time according to user's request.
The present invention realizes functions such as remote alarms, trip remotely, long-range combined floodgate, remote monitoring, teledata read through the long-distance management system of power supply administration.The near-field communication of RFID then can be accomplished supplementing with money electric energy meter.
The present invention utilizes the remote radio communication transmitted data on network, realizes the telemanagement to electric energy meter.The The data of transmission the algorithm of authentication and encryption, the data security height.The The data ciphertext of transmission is sent.Transmitting terminal is asked for a random number to receiving end; Data with the needs transmission; Send after using this random number and key through certain algorithm for encryption; Receiving end carries out operations necessary after using same random number and key through certain algorithm deciphering the data of receiving again, and transmitting terminal is sent confirm that data notification operates successfully or fail.Such as revising the each recharge amount of stored value card; A random number is asked for to electric energy meter earlier by main website (remote server); Send to electric energy meter after will purchasing electric data encryption then, decision operation content after electric energy meter uses same random number with the data decryption of receiving is if revise successfully; Then the amended amount of money is write electric energy meter, and the return success confirmation.Then return abnormal information if operation is unsuccessful, main website according to circumstances will issue modify instruction once more.Closing a floodgate for the tripping operation of relay then is to realize through the near-field communication of RFID.
Principle of work of the present invention is following:
The one, electric energy computation chip is gathered the real-time power network parameter, microprocessor through the SPI interface with the data of computation chip collection analyze, calculation process, and the data after the analyzing and processing are kept in ram region and the storer; The 2nd, the safety certification between microprocessor and the RFID communication facilities has only through purchasing the electricity operation to electric energy meter after the authentication; The 3rd, utilize GSM, GPRS, cdma network that the data that abnormal data perhaps needs to carry out are sent to remote server between microprocessor and the wireless communication module.The 4th, microprocessor will carry out analysis and judgement through the data that GSM, GPRS, cdma network receive, and the data of server needs taken out from RAM or storer send server to, and the instruction that server is assigned is carried out immediately.
