The input part of the n-th control module notifies the n-th working sensor, is obtained the fixed sequence program number of the n-th sensor by communication signal line, is labeled as n position, 1≤n<N;
The efferent of the n-th control module provides enable signal to notify (n+1)th working sensor, and controls the n-th sensor and await orders, and is obtained the fixed sequence program number of (n+1)th sensor, be labeled as n+1 position by communication signal line.
Additionally provide a kind of method adopting multinode measurement and positioning device according to claim 1, comprise the following steps:
(1) each node powers on, initialization, and N number of sensor is set to armed state;
(2) order of microprocessor is waited for;
(3) whether the IN pin of decision node has enable signal, is, performs step (4), otherwise performs step (2);
(4) with microprocessor communications allocation address information;
(5) judge whether the complete order of host assignment, be, performed step (6), otherwise perform step (4);
(6) the OUT pin of node provides enable signal, and node self is set to armed state.
The present invention, by control module and microprocessor, when powering on, first sets, and only have first node work, all the other nodes are all standby; Then with first node communication, obtain the fixed sequence program number of first node, be labeled as No. 01 position, then notify that first node has recorded, allow the output pin of first node provide enable signal, tell that second node is started working, and self gets back to armed state; And so forth, during every task, whole Data-Link all only has a node in work at every turn, so whole location number and fixed sequence program number are formed list data; Therefore make user can automatically position each sensor node in use, greatly simplify testing process, reduce cost of labor, accurate positioning, later maintenance is easy.
Accompanying drawing explanation
Fig. 1 is the structural representation according to multinode measurement and positioning device of the present invention;
Fig. 2 adopts the process flow diagram according to the method for multinode measurement and positioning device of the present invention.
Embodiment
As shown in Figure 1, this multinode measurement and positioning device, after N number of sensor series forms N number of node, package is in a cable, extracting power supply cord, ground wire, communication signal line, wherein N be greater than 1 integer, time initial, N number of sensor is armed state, this multinode measurement and positioning device comprises N number of control module and a microprocessor, and microprocessor is connected with communication signal line, and each control module connects a sensor, each control module comprises input part and efferent, and is configured to:
The input part of the n-th control module notifies the n-th working sensor, is obtained the fixed sequence program number of the n-th sensor by communication signal line, is labeled as n position, 1≤n<N;
The efferent of the n-th control module provides enable signal to notify (n+1)th working sensor, and controls the n-th sensor and await orders, and is obtained the fixed sequence program number of (n+1)th sensor, be labeled as n+1 position by communication signal line.
The present invention, by control module and microprocessor, when powering on, first sets, and only have first node work, all the other nodes are all standby; Then with first node communication, obtain the fixed sequence program number of first node, be labeled as No. 01 position, then notify that first node has recorded, allow the output pin of first node provide enable signal, tell that second node is started working, and self gets back to armed state; And so forth, during every task, whole Data-Link all only has a node in work at every turn, so whole location number and fixed sequence program number are formed list data; Therefore make user can automatically position each sensor node in use, greatly simplify testing process, reduce cost of labor, accurate positioning, later maintenance is easy.
Preferably, this multinode measurement and positioning device also comprises self-test unit and fault alarm unit, and self-test unit detects that communication signal line is reported to the police by fault alarm unit after not collecting data.At regular intervals, self-inspection once.If run into and have communication failure, reexamine a list.If be have problem really, prompting failure warning.After trouble shooting, reorientate.
