The power input of power module U9 is external power supply and powered battery dual mode.
The monitoring handling procedure of host adapter and terminal adapter can adopt the C Programming with Pascal Language, is convenient in the future transplanting and maintenance.
Among the present invention, first central processing unit U1 of host adapter and the second central processing unit U7 of terminal adapter all adopt the MSP430 chip of American TI Company, in the data-signal gatherer process, can realize the efficient data calculation process, equipment control circuit and various measuring transducer data from monitored scene, the signal that collects is carried out adopting the mode of serial communication to transmit after A/D transforms.
As shown in Figure 2, the course of work of host adapter is:
The first charger U4 gives the first gsm wireless communication module J1 (model is TC35) power supply by No. 4 pin output 3.3V voltages, and whether the first central processing unit U1 controls the first charger U4 by the PWR pin output voltage; Read and write data by pin CCIN and CCIO between the first gsm wireless communication module J1 and the SIM circuit J2, a SIM circuit J2 is powered by pin CCVCC by the first gsm wireless communication module J1.
The first central processing unit U1 communicates by pin RXD35 and TXD35 and a GSM communication module J1, and after a GSM communication module J1 received SMS/phone/timing quarter-bell, RING35 pin output high level was notified the first central processing unit U1; The first central processing unit U1 analyzes its frequency: 450Hz and represents mobile phone to put through by catching the signal by the EPP1 audio output output of a GSM communication module J1, and on behalf of mobile phone, 920Hz hang up; The first central processing unit U1 passes through URXD1/UTXD1, URXD0/UTXD0 and main control computer, redundant computer (two computers are standby each other) carry out serial communication, finish conversion between Transistor-Transistor Logic level and 232 standard serial ports by first serial level translator U2 and second serial transducer U3; During normal condition, the data of two computer receiving terminal adapter transmissions simultaneously; The first central processing unit U1 judges from the pulse train of PC1-ACT and PC2-ACT whether two computers are working properly by receiving, two computers send data by PC1-REQ and PC2-REQ to first central processing unit U1 request, and wherein PC1-REQ priority is higher than PC2-REQ.The first central processing unit U1 is by Rest-bit and the regular first house dog U5 that resets of Off-rst; if the first central processing unit U1 does not send reset signal to the first house dog U5 in a period of time; illustrate that the first central processing unit U1 makes mistakes or shuts down, then the RST pin of the first house dog U5 restarts the first central processing unit U1.
Host adapter has the two-node cluster hot backup function, promptly under the situation that a computer damages, automatically control is switched to another redundant computer, thereby realizes the free of discontinuities transmission of data.
As shown in Figure 3, the course of work of terminal adapter is:
The second charger U6 gives the second gsm wireless communication module J3 (model is TC35) power supply by No. 4 pin output 3.3V voltages, and whether the second central processing unit U7 controls the second charger U6 by the PWR pin output voltage; Read and write data by pin CCIN and CCIO between the second gsm wireless communication module J3 and the 2nd SIM circuit J4, the 2nd SIM circuit J4 is powered by pin CCVCC by the second gsm wireless communication module J3.

1) initialization second central processing unit (U7);
2) the initialization second gsm wireless communication module (J3);
3) judge whether the second gsm wireless communication module (J3) has signal, if there is not signal, again to second gsm wireless communication module (J3) initialization; If signal is arranged, then reading state parameter and flow process parameter from flash memory, and the workflow of setting program and the operating state of equipment according to this, enter from maintenance operation, time-delay and waiting event take place, and judge whether that then event occurs, if there is not incident to take place, then get back to from the maintenance operation state, time-delay and waiting event take place; If event occurs, then judge the event type;
4) judge the event type, if:
A. note sends, and judges then whether transmission is successful; If success, then time-delay and waiting event take place, if event occurs repeating step 4 then); If success is not then dialed the phone that reports an error, and entered from maintenance state, time-delay and waiting event take place, if event occurs repeating step 4 then);
B. have phone to dial in or transfer to, then whether judgement is dialled in or transfers to successful; If success, then if time-delay and waiting event take place event occurs repeating step 4 then); If not success, then in flash memory, do not deposit error logging in and restart;
C. import power supply type and change, then judge whether to be powered battery; If powered battery then enters low power consumpting state, time-delay and waiting event take place, if event occurs repeating step 4 then); If the external power supply power supply then enters normal operating conditions, time-delay and waiting event take place; If event occurs repeating step 4 then);
D. whether Programmable Logic Controller reception or transmission data are then judged reception or are sent successful; If success, time-delay and waiting event take place, if event occurs repeating step 4 then); If not success, then repeated attempt is received/is sent out, and repeatedly after the failure, sends note to the first gsm wireless communication module, and time-delay and waiting event take place; If event occurs repeating step 4 then);
E. receive note, analyze note, carry out the note order, time-delay and waiting event take place, if event occurs repeating step 4 then).
4. by the wireless communication adapter of the described long-range complexity monitoring of claim 1, it is characterized in that: described wireless forms of communication is a note, passive, promptly passive, initiatively poll or urgent active that communication mode has regularly.
5. by the wireless communication adapter of the described long-range complicated monitoring of claim 1, it is characterized in that: the power input of power module (U9) is external power supply and powered battery dual mode.
6. by the wireless communication adapter of the described long-range complicated monitoring of claim 1, it is characterized in that: the power end of the power end of a SIM circuit (J2) and the first gsm wireless communication module (J1) links together; The power end of the power end of the 2nd SIM circuit (J4) and the second gsm wireless communication module (J3) links together.
