Abstract
The utility model discloses a modular electric quantity acquisition and transmission device, which comprises a power supply module (1). The utility model is characterized by further comprising a CPU mainboard module (2) which is respectively connected with a carrier communication module (3), an infrared communication module (4) and a 485 communication module (5). The utility model has the advantage that software and hardware adopt the modular design and the interchangeability of the device is intensified, i.e. a lower voltage power line carrier manner or a 485 bus manner can be adopted to do data communication with a concentrator. A lower voltage power line carrier chip extensively used in the compatibility market makes the device have good interchangeability. Two 485 buses can form a loop. The device can diagnose the failure point of a managed 485 electricity meter through the software.
Description
Technical field
The utility model relates to a kind of modularization electric quantity acquisition and transmitting device, belongs to electric quantity acquisition and transmission technique field.
Background technology
In the prior art, the data communication means that electric power acquisition, transmitting device adopt are more, as various carrier communication chips, modes such as 485 buses, therefore for different data communication methods, electric power acquisition, transmitting device also have multiple model, and be convenient inadequately when installing and changing.
Summary of the invention
The purpose of this utility model is: provide a kind of modularization electric quantity acquisition and transmitting device of suitable several data communication modes, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: structure comprises and also comprises the cpu motherboard module by power module that the cpu motherboard module is connected with carrier communication module, infrared communication module, 485 communication modules respectively.
Above-mentioned modularization electric quantity acquisition and transmitting device, cpu motherboard module are connected with 2 485 communication modules.
Above-mentioned modularization electric quantity acquisition and transmitting device are connected with the carrier communication module by 6 input/output lines on the cpu motherboard module.
The utlity model has following advantage: software and hardware adopts modular design, has strengthened the interchangeability of equipment.Both can also can carry out data communication by the low voltage power line carrier mode by 485 bus modes and concentrator.Widely used low voltage power line carrier chip on the compatible market as the PL2000 series of Beijing lucky star journey company dawn, the SSC16 series of Qingdao Neusoft, the carrier chips such as ST7536 series of ST Microelectronics, makes device that good interchangeability be arranged.Use two-way 485 buses, can form loop, the 485 ammeter trouble spots that device can be managed by software diagnosis.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the interface synoptic diagram of CPU module of the present utility model and carrier module;
Accompanying drawing 3 is the structural representation of the utility model carrier communication module.
Embodiment
Embodiment of the present utility model: as shown in Figure 1, power module 1 provides power supply for each module, and cpu motherboard module 2 is connected with carrier communication module 3, infrared communication module 4,485 communication modules 5 respectively.Cpu motherboard module 2 adopts the mainstream chip of existing market, and this chip has EEPROM, need not expand ferroelectric memory, has reduced components and parts and cost.As shown in Figure 2, on cpu motherboard module 2, be connected with carrier communication module 3 by 6 input/output lines 6, present widely used carrier chip, its data communication mainly contains the synchronous clock line, send data line and receive data line, some chip also has 1 control line, and this device leaves 6 input/output lines 6 at the CPU end, make it can satisfy present widely used carrier chip, and can satisfy the carrier chip that to release in the future.
Infrared communication module 4 adopts the product of existing markets, can check preceding 8 days electric weight of electric energy meter, the duty of preceding 5 days electric weight, current electric quantity and every ammeters by the hand-held palm PC with infrared communication function.485 communication modules 5 are connected with 485 ammeters by 485 buses, the realization communication function, and cpu motherboard module 2 is connected with 2 485 communication modules 5, can form loop, the 485 ammeter trouble spots that can manage by software diagnosis.
Widely used low voltage power line carrier chip on the carrier communication module 3 compatible markets, its structure by carrier chip 7, send filtration module 8, the module that accepts filter 9,220V low-voltage power line interface 10 and form with the Interface Terminal 11 of cpu motherboard module 2.When sending data by carrier wave, the data bit that cpu motherboard module 2 will send is passed to carrier communication module 3, carries carrier chip 7 the binary-level data-modulated is become analog quantity, and be loaded on the low-voltage power line by pickup coil; Carrier communication module 3 through after the filtering, is reduced to binary data by carrier chip 7 with its demodulation with received simulating signal then, thereby realizes electric line carrier communication.
