Background technology
Communication power supply safe and reliable is the essential condition that guarantees the normal operation of communication system, this wherein last guarantee of carrying as power of accumulator, the last insurance in the communication power supply beyond doubt.But accumulator is a high link of accident rate in the communication power supply at present, this shows the safe and reliable necessity and the urgency that improve the accumulator operation.
But for standby time and the actual capacity of checking battery pack, guarantee the normal operation of system, generally need be to the property checked discharge test once in battery pack every year.The performance of battery pack depends on the poorest joint of performance in the whole Battery pack, therefore need in discharge process, monitor by the voltage to each batteries, so that monomer battery voltage fall to stop in limited time under the discharge discharge, avoid battery damage, and the performance of each batteries analyzed.
At present, in electric system, the accumulator capacity testing apparatus generally is that discharge load adds the monomer battery voltage acquisition system.Although this kind equipment has satisfied the needs of on-the-spot battery service substantially,, this kind equipment exists not enough.Such as: discharge time is long, the operation of equipment complexity; Discharge data can not long-distance transmissions, and wired mode is adopted in the collection of site monomer cell voltage, and time-consuming, security is low, is difficult for realizing data sharing, phenomenons such as cell voltage acquisition precision difference.
Summary of the invention
Problem to be solved in the utility model is: the measuring method to accumulator in the existing electric system can not satisfy user demand, needs personnel's execute-in-place, and is time-consuming, is unfavorable for the quick monitoring of battery condition.
The technical solution of the utility model is: long distance wireless measuring battery system, comprise a plurality of battery pack, battery pack is made up of cell batteries, also comprise the wireless battery voltage acquisition module, intelligent battery group load testing instrument, real time data transmit-receive platform and host computer, the corresponding wireless battery voltage acquisition module that connects of each single battery, intelligent battery load testing instrument connects each single battery, the wireless battery voltage acquisition module connects intelligent battery load testing instrument, and the wireless battery voltage acquisition module is connected with host computer by the real time data transmit-receive platform.
Described real time data transmit-receive platform is the wireless signal repeater, and the wireless signal repeater inserts the electric power LAN (Local Area Network) by LAN interface, connects host computer by the electric power LAN (Local Area Network).The microprocessor of wireless signal repeater is a dual-cpu structure.
The wireless battery voltage acquisition module comprises AD modular converter and FSK radio frequency transceiving module, and the AD modular converter connects single battery, and the FSK radio frequency transceiving module is connected with the real time data transmit-receive platform by radio communication.
The utility model is realized the remote monitoring of accumulator in conjunction with network transmission technology and data acquisition technology, has solved the deficiency of conventionally test method, has realized technological innovation, and its beneficial effect has:
First: realized the remote collection of each monomer battery voltage of battery pack, need not on each cell, to connect at the scene to gather line; Adopt the wireless collection monitoring technique, need not personnel's field wiring, the tester Long-distance Control, automatic data collection is increased work efficiency greatly and is guaranteed site safety;
Second: the battery pack information that the scene is gathered by the wireless battery voltage acquisition module inserts the electric power LAN (Local Area Network) by terminal LAN mouth, realize the transparent remote live transmission of field test data, it is intelligent, information-based, networked that battery service and management are realized.

Embodiment
As Fig. 1, the utility model is measured at a plurality of battery pack, battery pack is made up of cell batteries, the utility model comprises wireless battery voltage acquisition module 1, intelligent battery group load testing instrument 2, real time data transmit-receive platform 3 and host computer 4, the corresponding wireless battery voltage acquisition module that connects of each battery pack, intelligent battery load testing instrument connects accumulator, the wireless battery voltage acquisition module connects intelligent battery load testing instrument, and the wireless battery voltage acquisition module is connected with host computer by the real time data transmit-receive platform.Described real time data transmit-receive platform is the wireless signal repeater, and the wireless signal repeater inserts the electric power LAN (Local Area Network) by LAN interface, connects host computer by the electric power LAN (Local Area Network), and the microprocessor of wireless signal repeater is a dual-cpu structure.The wireless battery voltage acquisition module comprises AD modular converter and FSK radio frequency transceiving module, and the AD modular converter connects single battery, and the FSK radio frequency transceiving module is connected with the real time data transmit-receive platform by radio communication.
The utility model implementation procedure and working example are described below:
1) on the battery pack at the scene, each single battery connects the wireless battery voltage acquisition module of respective amount, the major function of wireless battery voltage acquisition module be voltage analog with accumulator after the conversion of AD modular converter, with wireless mode the battery tension signal is sent to the wireless signal repeater by the FSK radio frequency transceiving module.Owing to adopted the highly sensitive radio-frequency (RF) receiving and transmission module of miniwatt to carry out the two-way transmission of data, need not on each single battery to connect and gather line, make operation very easy.
2) the wireless signal repeater is in order to receive the go forward side by side data transmit-receive impact damper of line data and protocol processes of each battery tension signal.The microprocessor of wireless signal repeater adopts two cpu models, can be uninterruptedly carry out the transmitting-receiving management of data according to certain time sequence to the wireless battery voltage acquisition module in the communication context, microprocessor is handled parameters such as the voltage of each battery pack, electric current, temperature to host computer with field data is long-range by the LAN mouth simultaneously.
3) host computer is by the reception of LAN (Local Area Network) realization to on-the-spot battery pack information, and will control and measuring command be sent to the wireless signal repeater, the wireless signal repeater is finished the forwarding to the host computer order, according to order character, control each wireless battery voltage acquisition module respectively and finish collection the single battery information of voltage, perhaps control the start and stop of site intelligent accumulator load tester, realize the property the checked discharging function of battery pack; Simultaneously show on-the-spot battery pack information in real time,, finish the long distance wireless of on-the-spot battery pack information is measured and control with information such as curve, form, histogram form display voltage, electric current, capacity at host computer.
