Detailed description of the invention
The present invention utilizes the vibration signal of low-power consumption MEMS acceleration pick-up gathering project machinery, realizes the condition monitoring of construction machinery and equipment; Adopt interrupt working manner to reduce energy consumption, lengthen working hours.This tracker both had common tracker without external cord, can the advantage of flexible hidden installation, can also add up the work-hours of construction machinery and equipment, for past-sale service work provides foundation, be the regeneration product of current tracker.
Referring to Fig. 1, the feed circuit that the present invention includes micro controller system U1, wireless communication module U4, satellite positioning module U2, vibration sensor U5 and be made up of battery B and source switch chip U3.Vibration sensor U5 adopts the LIS3DN acceleration pick-up of ST company, have low in energy consumption, survey precision is high, cost performance advantages of higher, the interrupt pin INT of this sensor is directly connected with the interrupt pin of micro controller system U1.Micro controller system U1 adopts MSP430, is communicated with vibration sensor U5 by spi bus, realizes the setting of sensor parameters and the reading of Detection Information.Wireless communication module U4 can adopt G610, and that satellite positioning module U2 adopts is NEO-6M.What source switch chip U3 adopted is XC6221 chip, has the features such as pressure drop is low, breaking circuit is little.
This tracker is arranged on the body of monitored engineering mechanical device, is in sleep pattern when vibration sensor U5 is flat, and micro controller system U1 is also in sleep pattern.During construction machinery and equipment work, body can vibrate, and when the vibration acceleration amplitude of construction machinery and equipment exceedes the threshold value of setting, vibration sensor U5 wakes up automatically, and wakes micro controller system U1 up by producing interrupt signal.
In order to extend the power-on time of battery B, vibration perception and the timework of tracker all adopt interrupt working manner.At vibration sensor U5 not on period, micro controller system U1 is set to the power-down state more economized on electricity.At satellite positioning module U2 and wireless communication module U4 not on period, source switch chip U3 stops to they power supplies.
The working process of this tracker is as follows:
Micro controller system U1 and vibration sensor U5 is in sleep electricity-saving state at ordinary times.Vibration sensor U5 produces and interrupts application, wake micro controller system U1 up after finding construction machinery and equipment vibration.Micro controller system U1 is waken up the timer of rear its inside of startup and opens timer interruption responding to switch, and timer is started working.Then, vibration sensor U5 is set to power-down state by micro controller system U1, and micro controller system U1 also sleeps immediately.
After timing terminates, timer produces and interrupts, wake micro controller system U1 up, by the accumulative upper timer interruption time span value (this value is traditionally arranged to be about 30 seconds) of accumulative register in man-hour of therein after micro controller system U1 is waken up, and timeing closing device interrupt response switch, open the interrupt response switch of vibration sensor U5 simultaneously and vibration sensor U5 is set to sleep state.Then, micro controller system U1 oneself also enters sleep state.
If vibration is also continuing, vibration sensor U5 again can produce and interrupt application, and accumulative man-hour, register can add up the preceding paragraph time again.If mechanical vibration no longer continue for, then standing time is cumulative.The time of accumulative register memory storage in man-hour is exactly the cumulative operation time of construction machinery and equipment.
