Embodiment
Referring to Fig. 1, the utility model provides a kind of multi-port modular on-line monitoring system based on wireless sense network, should comprise data acquisition unit, data-interface, data processing unit, data transmission unit and power supply based on the multi-port modular on-line monitoring system of wireless sense network; Data acquisition unit is connected with data processing unit by data-interface; Data processing unit comprises MCU chip, optical coupling isolator, storer and low power detection circuit; Data-interface accesses the MCU chip by optical coupling isolator; Data transmission unit, storer, power supply and low power detection circuit access respectively the MCU chip.
Data acquisition unit is sensor; Sensor is the one or more combination in crack sensor, displacement transducer, historical relic shell temperature sensor, historical relic body surface humidity sensor, historical relic body surface acidity-basicity sensor and historical relic body surface color change video frequency pick-up head, and these sensors have been completed separately or jointly the enforcement on-line monitoring to stone carving body in the district of outdoor ruins.
Data processing unit also comprises the house dog that is connected with the MCU chip, the indicator that is connected with the MCU chip; Indicator is the LED lamp group that different colours consists of.
Power supply is civil power and/or battery.
Data-interface is the RS485 data-interface; Data transmission unit is the RF communication unit.
Below in conjunction with accompanying drawing 1, the utility model is elaborated: RF part 2: carry out the send and receive of data, transmitted power is 20dbm; Hardware watchdog 6: when the CPU race flew, CPU resetted; Indicating section 5: the duty of indicating primary module by LED; Red light is lighted expression and is powered on, and amber light is lighted expression and sent, and green light is lighted expression and received.Low electro-detection part 3: during lower than 12V, the voltage sign in packet is set to 1 when supply voltage, when supply voltage is not less than 12V, the voltage sign is set to 0, and sends to father node.Storage chip 4: the configuration information that is used for storing primary module.Light-coupled isolation 7: carry out the signal isolation with primary module and from module; 485 modules 8: primary module with adopt the RS485 bus from module communication, agreement adopts the MODBUS agreement.Power pack 9: outside+12V power supply is converted to respectively+3.3V ,+5V, primary module, sensor assembly are supplied with respectively in+12V power supply.The sensor group comprises one or more from module 10: can be any sensor assembly, as various sensors such as crack, displacement, temperature, potential of hydrogen, humidity.The power supply of module is controlled by primary module.Principal and subordinate interface definition :+12V ,+5V, A, B, GND+5V(is standby)
Principle of work of the present invention is: by high-tech means, it is carried out uninterrupted monitoring in 24 hours, the inclination of historical relic body and the Crack change on surface are monitored by sensor assembly, carry out data acquisition by sensor assembly, then send to primary module by the RS485 bus, primary module is processed, and sends to user terminal by primary module by wireless network at last.
Due to on-the-spot various kinds of sensors One's name is legion, adopt modular design concept, the point of needs monitoring is become be module one by one, and give corresponding address, like this to layouting and the maintenance in expansion and later stage provides a great convenience.
The course of work of principal and subordinate's module is as follows:
Primary module powers up, and powers up rear primary module and first searches net, after searching out network, just sends 03 function code on the RS485 bus, and 03 function code is that the address from module is inquired about, and has seen which hangs on bus from module; Send the address and send one by one from 01～08, when certain is responded from module, remember that this is from the address of module;
After 03 function code sends, then send 04 function code, the effect of 04 function code is, read the data from module, the address that sends is the address that just now inquired from module, and every transmission one bag read command just waits from module and replys packet, read at the appointed time from the data of module and just send immediately next read command from module, otherwise just wait until that official hour sends next read command from module again.
When all the inquiring from module data of all carries, primary module carries out the data packing, will pack from the data of module according to different node identity respectively, then issues father node according to certain time interval.
When wherein any data from module did not send out, primary module was retransmitted 3 times, does not still send successfully, again searches network, began to retransmit from first node.If again search net, still do not search out, search three times, just enter low power consumpting state when still not searching out.As after searching out, just resend in order.After being sent completely, primary module breaks from module for power supply, then enters low power consumpting state, and the time of low-power consumption can be set.After setting-up time arrived, primary module entered again next circulation, repeats above-mentioned step.
The power supply aspect adopts civil power to combine with battery, and civil power is preferential, when mains failure occurring, can switch to powered battery, in case by mains-supplied, and can charge to battery in the city power recovery.Lower than+12V, primary module is informed user terminal, hangs down electric alarm when supply voltage.
For on-the-spot complex environment, consider that on-the-spot general few people go over, will cause a large amount of loss of datas in case the CPU deadlock occurs, adopt hardware watchdog to nurse, improved greatly Systems balanth.
