Middle low power wireless station mode: the advantage of this kind mode is: the systematic running cost after equipment puts into operation is low.Shortcoming is: power is bigger, and the power devices system is brought bigger burden; Be subjected to external disturbance easily and other system is caused interference; Used frequency will obtain the Radio Management Commission and examine and pay the frequency usage charges every year.
The SMS transmission mode:
The mobile phone signal overlay area has reached most of both urban and rural area.Various factorss such as the workload that realizes from system, complexity, reliability, cost are taken all factors into consideration, and it is feasible technically that the mobile phone short message mode is adopted in the transmission of alerting signal.But, in view of electric system remains the too many (zone at county level of one 300,000 population of monitored outdoor facilities, user transformers reaches several thousand, the city of million people's mouth, bar/the tower of the above circuit of its 10KV reaches several thousand bases), adopt a mobile phone card (by most favorable telecommunications price at present: 20 yuan/month) if each is monitored, then the telecommunications usage charges of every month reach tens thousand of units (even tens0000 yuan).So high expense is very unfavorable to large-scale promotion from now on.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of wireless and GSM technology hybrid building data acquisition device simple in structure for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: wireless and GSM technology hybrid building data acquisition device, it is characterized in that, this device comprises GSM transport module, wireless transport module, controller, electric power system, described GSM transport module, wireless transport module are connected with controller respectively, and described controller is connected with electric power system.
Described GSM transport module comprises GSM baseband processor, GSM radio-frequency module, supply module (ASIC), flash memory, ZIF connector, antennal interface, and each device in the said GSM transport module interconnects.
Described controller comprises Flash program storage, data SRAM, programmable counter array (PCA), can be configured to the WatchDog Timer of different time scope, two enhancement mode UART, byte type I2C Bus interface, and each device in the above-mentioned controller interconnects.
Described electric power system comprises solar powered subsystem, storage battery power supply subsystem.
Compared with prior art, the present invention has the following advantages:
(1) remote station power is low, volume is little, power consumptive province, easy for installation;
(2) low-power is difficult for forming interference, can according to actual needs electrical facilities at any areas be monitored;
(3) system's construction period is short, cost is low, and networking is convenient and swift;
(4) radio band of Shi Yonging belongs to country does not have the open frequency range of committee, needn't apply for and pay frequency occupancy (other frequency is wanted declaration and paid occupancy);
(5) operating cost after system builds up is low, is suitable for large-scale promotion and uses;
(6) remote station belongs to non-maintaining type, can realize system's remote signalling upgrading at central station.
