Background technology
Along with electricity market and development of economic construction, the power distribution automation series terminal is more and more general in application on power system, and this just exists large quantities of terminals dispatch from the factory parameter configuration, on-site maintenance and the very big problem of parameter modification workload after sale.The setting of power distribution automation series terminal parameter comprises the terminal communication parameter, the electric energy meter parameter, network parameter, pulse parameter, quantity of state parameter etc., general all is that special parameter configuration software is installed on all-purpose computer, finish communication between computer and the terminal by the RS-232 serial ports, if these parameters are provided with at each lane terminal respectively one by one by computer, not only workload is big, and inefficiency, especially under the situation about safeguarding at outdoor scene, if outdoor temperature is too high or too low, perhaps there is not power supply, these environmental factors all can cause and can't adopt notebook to finish the parameter setting, the computer volume is big in addition, price is expensive, especially is not easy to be carried to the scene of using.
The utility model content
The utility model is at the deficiencies in the prior art, and it is extensive to have designed and developed out a kind of use occasion, and volume is little, and low price and parameter easy to carry are provided with device.
The utility model is achieved through the following technical solutions:
A kind of parameter that is used for the maintenance of power distribution automated system terminal is provided with device, include battery, with meet the voltage transformation module that the device operating voltage is set in order to cell voltage is converted to, with in order to be connected the asynchronous serial communication mouth of PC or described terminal, with in order to control the button that device is set, and in order to receiving the PC data and storage is transferred to terminal, and receive the CPU that carries out from key controlled instruction.
Described battery output is connected with the voltage transformation module input, and the voltage transformation module output is connected with described CPU; Described asynchronous serial communication mouth one end is connected with CPU is interactive, and the other end is connected with described terminal with PC respectively; The signal output part of described button is connected with the cpu signal receiving terminal.
A kind of parameter that is used for the maintenance of power distribution automated system terminal is provided with device, also include display unit, the signal input part of described display unit is connected with the signal output part of CPU, and described CPU also is delivered to display unit and demonstration in order to state and the relevant parameter signal that device will be set.
A kind of parameter that is used for the maintenance of power distribution automated system terminal is provided with device, described asynchronous serial communication mouth is respectively RS232 interface and RS485 interface, be used to be provided with that device is connected with PC is the RS232 interface, what be used for being connected with described terminal is the RS485 interface.
A kind of parameter that is used for the maintenance of power distribution automated system terminal is provided with device, and described CPU is built-in with memory.
Adopt this kind on-site terminal maintenance parameters that device is set, only need press the configuration parameter initiating key and can realize configuration automatically all parameters of terminal, configuration at the different terminals parameter can be finished by revising Control Software at host computer, the required components and parts of hardware that this kind on-site terminal maintenance parameters is provided with device are few, only by CPU and peripheral circuit thereof, RS485 and RS232 interface circuit, power circuit and two light-emitting diodes and a key groups achievement can replace all-purpose computer fully, realize all parameter configuration that computer can be finished, low in energy consumption, machine volume is little, applied widely, be easy to carry about with one, low price has tangible economic benefit.
