The compressing pin of block and thin film potentiometer, fixed pin etc. are between connection circuit, analog-to-digital conversion module and wireless communication module
Connection circuit etc. belongs to the prior art.Using analog-to-digital conversion module, after wireless communication module, reflection tree breast-height diameter can be changed
Compressing pin and a fixed pin between voltage change data real-time transmission to remote server or hand-held monitoring equipment, people
Tree breast-height diameter can be monitored in real time, do not need survey crew and enter field, protect personal safety, improve efficiency and safety.
Certainly, wireless communication module can use the wireless communication module containing Zigbee module.In this way, can be in the woods
In each tree on be respectively mounted the measuring system；The Zigbee module is used to converge the change information of collected trunk radius
It is always sent to coordinator, coordinator can send remote server for collected data by 4G module or hand-held monitoring is set
It is standby.When there are multiple terminal signaling acquisition nodes, the function of networking can be realized by Zigbee network, therefore can achieve
Measure the effect in full wafer forest land.Zigbee module, 4G module, server, hand-held monitoring equipment etc. belong to the prior art.

Specific embodiment
Referring to attached drawing 1,2,5, the real-time tree breast-height diameter system of the utility model has bandage 10, and the bandage 10 is
Node 7 is welded and fixed in stainless steel band, stainless steel band one end, and the other end of stainless steel band is equipped with free end 8；Fixed-node 7 is logical
The pin for the mounting hole 1,3 crossed in stationary nodes is fixed on surveyed trees, and the back side of stationary nodes is (in trees
Side) there are a width and the groove 14 slightly wider than bandage 10, the bottom surface of groove is provided with blind hole 15, and contact 2 is arranged in blind hole,
The pressure spring 16 is between blind hole bottom surface and contact.The free end 8 of stainless steel band is passed through out of groove after a week around trees.
One end of spring (tension spring) 18 is connected with free end 8, the other end 11 and 7 phase of stationary nodes of the spring 18 after trees 17
Even.To the surface mount of groove thin film potentiometer 9 on the bandage for passing through groove, the paste position of thin film potentiometer according to
Actual conditions are chosen, it is necessary to assure the groove that passes through of thin film potentiometer is pasted, meanwhile, contact 2 presses under the effect of pressure spring 16
Firmly thin film potentiometer.For protective film potentiometer, thin film potentiometer can be encapsulated to upper layer protecting film and pasted again later.
When arboreal growth stretches, the position of contact pressing thin film potentiometer changes.There are three the thin film potentiometers
Pin is followed successively by fixed pin 4, oppresses pin 5, fixed pin 6；It is fixed resistance between two fixed pins 4,6, compressing is drawn
Resistance value between foot 5, fixed pin 6 is different according to the potentiometric position of 2 press membrane of contact and changes.
The pin of thin film potentiometer is connected with diaphragm pressure sensor resistive voltage signal conversion module, diaphragm pressure sensing
Device resistive voltage signal conversion module is connected with Zigbee module, thin film potentiometer, diaphragm pressure sensor resistive voltage signal
Conversion module and Zigbee module together form a complete terminal signaling acquisition node.
