Description
Technical field
The utility model relates to a kind of terminal box, relates in particular to a kind of terminal box of electric energy meter, specifically a kind of terminal box that communication module is provided with the plug-in type physical interface that extends out for electric energy meter.
Background technology
Along with the progress of science and technology and the development of society, people are also more and more higher for the requirement of the metering ammeter in daily life and the commercial production, as everyone knows, traditional manual metering mode efficient is low, not only can bring puzzlement to the user, also have labor intensive, drawback that material resources are big, thereby telemetering electric meter is valued by people more and more in recent years.Be exactly that in brief a communication module is made the table that unit independently is contained in electric energy meter and cover, carry out communication, and the data upload that the obtains data center to Utilities Electric Co. is focused on again with the data-interface of the base table of electric energy meter.But this implementation is because spatially be subjected to the limitation of the physical dimension of electric energy meter, so it is poor to extend out the Scalable Performance of communication module, heat dispersion is poor, in addition, the replacing of communication module needs field wiring, causes workmen's inefficiency, workload big.
Open day be that a kind of intelligent electric energy metrical that October 1, publication number in 2003 are CN2577295Y is controlled integrated ammeter and disclosed such technical scheme: its adopts a microprocessor CPU and a plurality of electronic devices and components, pack with plastic casing, design has panel on the shell, the metering of a plurality of user loops, control device height are integrated, constitute electric energy sampling counting module, center microprocessor module, serial data read-write memory module, serial communication module, drawing lock control module, working power module, display module and key circuit module; Most of components and parts of electric energy sampling counting module are integrated on the counter plate, center microprocessor module, serial data read-write memory module, serial communication module are integrated on the CPU board, drawing lock control module is integrated on the circuit board of operating a switch, the working power module is integrated on the Switching Power Supply plate, and display module and key circuit module are integrated in display board.This utility model is integrated in functional module on the CPU board, realized the ammeter initialization, the electric energy sampling counting, the electricity consumption data-storing, superpower is handled, processing reports an error, externally communication, long-range drawing, close a floodgate and handle, functions such as demonstration and calibration, but still there is shortcoming in this ammeter, the key modules serial communication module of this utility model is integrated on the CPU board, make user's intelligence when using this product that it is used as intelligent electric meter, there is not multiple selection, there is the communication module that places in the whole table on volume, to be restricted again, cause its heat dispersion poor, reduce serviceable life, in addition, communication module is upgraded or when changing, change complex procedures, even can't change, have serious drawback.
The utility model content
The utility model is at existing communication module upgrading in the existing intelligent electric meter or change difficult, problems such as Scalable Performance is poor, heat dispersion difference, provides a kind of for extending out the intelligent electric meter terminal box that communication module is provided with the plug-in type physical interface.
In order to solve the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of electric energy meter terminal box, comprise the terminal box shell, be arranged on the power lug on the terminal box and be arranged on external connection hole on the terminal box, on the terminal box of electric energy meter, be provided with the plug-in type physical interface, physical interface is included as the power interface that extends out the communication module power supply, and physical interface also comprises the data-interface that is used for base table and extends out the communication module exchange message.
Because what adopt is the communication module that extends out of plug-in type, different selections when using, the user is also just arranged, at the ordinary electric meter user, can adopt the base table scheme independently to realize, and at the intelligent electric meter user, the client can by on the terminal box for extending out the set physical interface of communication module, outside base table, add one and extend out communication module, thereby realize the function of intelligent electric meter, this design makes ordinary electric meter more succinct to the expanding of intelligent electric meter the time, convenient, peripheral hardware extend out the communication module perfect heat-dissipating, can not influence the operate as normal of electric energy meter.
For technique scheme, we also have further optimized Measures, and as optimization, power interface is connected with the phase line and the zero line of three-phase and four-line.Power interface is connected with power outlet on extending out communication module, for the work that extends out communication module provides voltage source, this design makes that the base table power supply that extends out communication module and electric energy meter is independent mutually, do not disturb mutually, partly can not exert an influence to electric energy metrical yet even be in data transmit-receive or set up under the bigger state of power consumptions such as link at communication module.In addition, power interface is a plug-in type, the security when having guaranteed operation.
As optimization, standard communication signal interface is connected in the base table of data-interface and electric energy meter.Standard communication signal in the base table is external, and be located at the base table outside with the plug-in type interface, this design wiring is more succinct, need not to tear open the table wiring, has solved the field wiring problem, has improved the work efficiency of installation personnel and the security of operation.
As optimization, data-interface is RS232, any one in RS485 or the near infrared mouth.Standard communication satisfies the communication protocol of standard, and the data communication passage for the client provides standard need not extra wiring.
As optimization, be provided with dividing plate between power interface and data-interface.It is noiseless that being provided with of this dividing plate guaranteed between high pressure, the low-voltage signal, improved the communication efficiency that extends out between communication module and base table.
As optimization, extend out communication module be provided with terminal box on the physical interface that matches of plug-in type physical interface.
Compared with prior art, advantage of the present utility model is: the physical interface of plug-in type is set on electric energy meter terminal box, thereby provides power supply and communication signal for extending out communication module, make electric energy meter have independence and extensibility in design.This electric energy meter both can adopt the base table scheme independently to realize the function of ordinary electric meter, also can load and extend out communication module by the plug-in type physical interface of peripheral hardware, this has also just been avoided ammeter dismounting again and wiring problem at the scene, improved the work efficiency of installation personnel, improved the security of operation, simultaneously, the embodiment of this communication module peripheral hardware also makes and the excellent radiation performance that extends out communication module has guaranteed the normal use of electric energy meter.
