External antenna and described housing junction arrange rubber washer.
Be described in more detail as follows below:
Ammeter is applied in open air usually, and some local temperature are high, and air humidity is high, the temperature difference at daytime and night
Change also can be larger, often suffers the burst weather of thunderstorm rain, therefore need product itself to tackle relatively harsh working environment.
This project is on shell, and there is corresponding stopper at the position of total interface to seal, and four screws are established
In respect of the screw plug of rubber, USB interface has silica gel plug, and is adhesive with waterproof mylar, and SIM card has the SIM card lid of plastics to seal, and also can paste waterproof mylar, and also there is rubber washer waterproof at the position that external antenna is connected with housing.
Through above-mentioned design, this product can accomplish 5 grades dust-proof, 4 grades of waterproof, can meet the building ring of ammeter
Border.
Electric power enterprise is exactly inevitably that some emergency situations cause electric network fault, and traditional ammeter is in burst
When situation occurs, record data that can only be passive, even likely can cause the loss of data because of the fault of system.
The chip of this project is built-in GPS and alarm mechanism, by the 3G network extensively covered, will go out to ask
Positional information and the relative alarm signal of the ammeter of topic are timely, power scheduling room and command centre is sent to exactly by 3G network, make commander can obtain information in real time, make correct judgement and decision-making, simultaneously also by the remote control function of module, certain correction is made to ammeter, or by the positional information that GPS uploads, arranges nearest engineering staff to rush to repair.
More than design improves the ability of remote command scheduling, shortens emergency repair time, increases work efficiency and visitor
Family satisfaction rate, improves emergency capability, reduces the impact that disaster causes.
The major technique innovative point of project
3G network is adopted to monitor ammeter and monitor
In order to realize remote real time monitoring to intelligent electric meter and monitoring, the mechanics of communication of employing is from initial electricity
Line of force carrier wave has developed into GSM and GPRS, but in actual application, the transfer rate adopting GPRS to reach only has 20kbps, and can only carry out the transmission of simple parameter.And 3G technology is relative to GPRS and gsm wireless network, transfer rate can reach 144kbps-2Mkbps, greatly improves the requirement of real-time of data transmission, accurately can transmit the acoustic informations such as the alerting signal that Site Detection terminal produces in addition.
Increase GPS chip and realize location, and utilize NodeB to realize AGPS precise positioning in software
This product adds GPS chip in the 3G communication module being applied to ammeter, add A-GPS functional realiey precise positioning simultaneously, in traditional GPS, catching the gps signal stage, in fact all possible frequency and code delay space will be searched for, and the frequency deviation caused by Doppler effect, more than one of the frequency range that GPS will be searched for, but the scope of whole Doppler frequency deviation will be searched for, it is very long that this also just causes traditional GPS receiver to search the star time first in startup, and A-GPS server has the GPS of a reference, the Doppler frequency deviation of satellite-signal can be calculated, Doppler frequency deviation information is sent to our module product by A-GPS server, the search volume of such module itself greatly reduces, only little several frequency zones are searched for, primary positioning time also just can reduce to only has several seconds.And its precision is under normal GPS working environment, can reach about 10 meters, can be rated as a kind of location technology that current positioning precision is the highest.
The Long-distance Control of 3G module itself
Remote control function is developed in the software of 3G module, only need transmission SMS as triggering, module just can start teleprocessing, at remote port, software firmware firmware upgrade is carried out to 3G module itself, or change parameter configuration, like this when network system is upgraded demand to 3G module, can accomplish to arrange technician to go spot replace module, greatly manpower can be saved, also rapid batch automatic business processing can be accomplished.
As shown in Figure 2, the electrical block diagram of the intelligent electric meter in the technical program.
GSM signal enters RF Connector from antenna.RF Connector is the connector aiming at test and design, and analyst to be connected to after RF Connector by special-purpose radio-frequency line with spectrum analyzer can the signal of testing and launching and reception.Signal enters RF SW(7130 by RF Connector).CPU can select to allow RF SW(7130 by control signal ANT_SEL (0:3)) signal of gating corresponding band (GSM850, GSM900, DCS, PCS), and select to receive or transmitting path.The signal of selected wave band, after RF SW output, enters the match circuit of corresponding wave band, is then input to 7100(CPU).After signal enters 7100 through low noise amplifier, mixing, demodulation, baseband filtering, A/D conversion, decoding, digital signal processing, convert simulating signal to through D/A and deliver to receiver.
The radiating portion principle of GSM is that voice signal converts simulating signal input CPU (7100) to through MIC.Change through A/D (converting simulating signal to digital signal) in CPU, coding, D/A, inner TX-VCO is sent in modulation, phase demodulation mixing, then by 7100 A22 pin and B23 pin export TX_GSM_HB and TX_GSM_LB radiofrequency signal respectively, this signal sends into power amplifier PA (7120) respectively after the matching network of outside, exports RF Switch (7130) to, then go out from antenna transmission through RF-Connector by power amplifier.
WCDMA signal enters RF Connector from antenna.RF Connector is the connector aiming at test and design, and analyst to be connected to after RF Connector by special-purpose radio-frequency line with spectrum analyzer can the signal of testing and launching and reception.Signal enters RF SW(7130 by RF Connector).CPU can select to allow RF SW(7130 by control signal ANT_SEL (0:3)) signal of gating corresponding band (BC1, BC5), and select to receive or transmitting path.WCDMA Received signal strength enters switch filter and the signal unbalanced transformation of corresponding wave band, then inputs 7100(CPU after exporting from RF SW).After signal enters 7100 through low noise amplifier, mixing, demodulation, A/D conversion, decoding, digital signal processing, convert simulating signal to through D/A and deliver to receiver.
The radiating portion principle of WCDMA is that voice signal converts simulating signal input CPU to through MIC
(7100)。Change through A/D (converting simulating signal to digital signal) in CPU, coding, D/A changes, inner TX-VCO is sent in modulation, phase demodulation mixing, then TX_OUT_U_LB is exported respectively by 7100, TX_OUT_U_HB2 radiofrequency signal, this signal sends into power amplifier PA (7115), (7110) respectively after external network, exported through duplexer filter to RF Switch (7130) by power amplifier, then go out from antenna transmission through RF-Connector.
Master chip can adopt the HSDPA chip QSC6270 of high pass qualcomm company, the maximum fortune of CPU
Line speed 600MHZ, FLASH are 1Gbits NAND and 256Mbits DDR.Main IC comprises CPU (Qualcomm QSC6270), FLASH (K521H57ACB-B060), GSM PA (TQM7M5022), WCDMA PA (ACPM-5201-LR1, ACPM-5205).
1, after machine powers on, after (PMU) obtains VCC_3V8, simultaneously 1302 open and shake and can produce 32.768KHz.
2, when 32.768KHz work after, PMU can first produce MSME, MSMP, RF1, RF2,
MSMC, RFA, TCXO voltage and 19.2MHz are fed to CPU, PMU, MEMORY, will reset after CPU obtains corresponding voltage and 19.2M clock, and provide reset signal and reset to PUM and MEMORY.To internal circuit be started after MEMORY, PMU obtain corresponding signal, and open corresponding function and signal is replied to CPU.At this moment state to find port to download software.
3, after MEMORY has software, CPU can run the program in oneself ROM, opens bus
Send chip selection signal, the program of reruning in Flash, enter normal power on mode.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
