Velocity sensor enters sleep state）If multiple comparative result is difference, judge that shape occurs in the traffic safety facilities
State changes, and the acceleration magnitude received for the last time is replaced to the state value preserved in original memory.Ratio is repeated by above-mentioned
Compared with, can eliminate because data dithering produce state erroneous judgement.
C) when judging traffic safety facilities there occurs state change, then it is to be in abnormality to judge the traffic safety facilities
It is in normal condition.
For example, the state value of certain traffic safety facilities preserved in memory（X, the acceleration magnitude of tri- direction of principal axis of Y, Z）Point
It is not：X0=0, Y0=0, Z0=5；The current state value of the traffic safety facilities received is X=0 respectively, Y=0, Z=- 5.
As follows carry out traffic safety facilities whether there occurs state change judgement：
X, Y, Z and X0, Y0, Z0 are subtracted each other respectively, obtained：ΔX=X- X0 ；ΔY= Y-Y0；ΔZ=Z-Z0；When Δ Z ≠ 0（On
Δ Z=- 10 in example）, then it is assumed that for traffic safety facilities there occurs state change, then it is in abnormal shape to carry out traffic safety facilities
The judgement of state or normal condition；When Δ Z=0 item thinks that non-generating state changes；
It is to be in abnormality or normal condition to judge traffic safety facilities as follows：By Z compared with 0, if greater than
Zero, then it is assumed that in normal condition, abnormality is considered at if less than zero.
In addition, it is necessary to explanation, from device in initial start to work, microprocessor first will be pre- in flash storage
The state value that the traffic safety facilities initial state value put reads and writes in memory as the traffic safety facilities uses.

Condition checkout gear；The state change message includes：The ID (such as IP address) of traffic safety facilities, state change identify, just
Normal status indicator or abnormality mark；
4. detection unit sends a heartbeat signal every a heart beat cycle to microprocessor, microprocessor is receiving the heart
Then confirm that detection unit is in normal condition after jumping signal.If microprocessor continuously makes a reservation for a heart beat cycle（Such as 3）No
The heartbeat signal is received, then judges that the detection unit is in abnormality（Such as break down）, microprocessor wake on wireless
Transmit-Receive Unit, and control wireless transmit/receive units to broadcast detection unit abnormal state information.
5. if microprocessor judges that the non-generating state of traffic safety facilities changes, microprocessor is passed to 3-axis acceleration
Sensor sends sleep signal, controls the 3-axis acceleration sensor to enter resting state；
6. microprocessor is regular（Such as every 2-3 seconds）Wake on wireless Transmit-Receive Unit, wireless transmit/receive units are started to work, that is, receive,
Send data；
7. if the wireless transmit/receive units receive the status data that other detection devices are sent（Including state change message, inspection
Survey unit exception status information）, then the wireless transmit/receive units status data received is forwarded to broadcast mode；
8. if wireless transmit/receive units are in the scheduled time（Such as 1-3 seconds）Data are inside not received by, or wireless transmit/receive units are
Through status data forwarding is finished, then microprocessor sends sleep signal to wireless transmit/receive units, and wireless transmit/receive units are into sleep
Dormancy state.
As shown in figure 4, the course of work of the main detection device is as follows：

Manage device；
2. microprocessor calculates the state of traffic safety facilities according to the acceleration information received by algorithm, and judges its shape
Whether state changes, and microprocessor continues to judge that the traffic safety facilities is to be in abnormality if state changes
（As there is a situation where topple over）It is in normal condition；
Specifically, microprocessor carries out traffic safety facilities condition adjudgement as follows：
A) microprocessor by the current acceleration value received compared with the state value preserved in memory before, if the two
It is identical, then it is assumed that not occur state change.
If b) the two is different, microprocessor control 3-axis acceleration sensor detects traffic safety facilities as bored again
Cylinder, railing etc. the acceleration magnitude of tri- direction of principal axis of X, Y, Z value, and by the acceleration magnitude received and previously stored state
Value is compared, and is repeatedly detected compared with（Such as 3 times, above-mentioned to repeat after detecting comparison, microprocessor controls three axis to add
Velocity sensor enters sleep state）If multiple comparative result is difference, judge that shape occurs in the traffic safety facilities
State changes, and the acceleration magnitude received for the last time is replaced to the state value preserved in original memory.Ratio is repeated by above-mentioned
Compared with, can eliminate because data dithering produce state erroneous judgement.
C) when judging traffic safety facilities there occurs state change, then continue to judge that the traffic safety facilities is in abnormal
State is in normal condition.
For example, the state value of certain traffic safety facilities preserved in memory（X, the acceleration magnitude of tri- direction of principal axis of Y, Z）Point
It is not：X0=0, Y0=0, Z0=5；The current state value of the traffic safety facilities received is X=0 respectively, Y=0, Z=- 5.
As follows carry out traffic safety facilities whether there occurs state change judgement：
X, Y, Z and X0, Y0, Z0 are subtracted each other respectively, obtained：ΔX=X- X0 ；ΔY= Y-Y0；ΔZ=Z-Z0；When Δ Z ≠ 0（On
Δ Z=- 10 in example）, then it is assumed that for traffic safety facilities there occurs state change, then it is in different to continue traffic safety facilities
The judgement of normal state or normal condition；When Δ Z=0 item thinks that non-generating state changes；
It is to be in abnormality or normal condition to judge traffic safety facilities as follows：By Z compared with 0, if greater than
Zero, then it is assumed that in normal condition, abnormality is considered at if less than zero.
In addition, it is necessary to explanation, for master device in initial start to work, microprocessor is first preset by flash storage
The traffic safety facilities initial state value state value that reads and write in memory as the traffic safety facilities use.

Confirm that detection unit is in normal condition after jumping signal.If microprocessor continuously makes a reservation for a heart beat cycle（Such as 3）Do not connect
The heartbeat signal is received, then judges that the detection unit is in abnormality（Such as break down）, microprocessor wake-up honeycomb number
According to unit, control the cellular data unit that detection unit abnormal state information is sent to server, after being sent, centre
Manage unit and send sleep signal to cellular data unit, control the cellular data unit to enter resting state；
5. if microprocessor judges that the non-generating state of traffic safety facilities changes, microprocessor is to 3-axis acceleration sensor
Sleep signal is sent, controls the 3-axis acceleration sensor to enter resting state；
6. microprocessor is regular（Such as every 2-3 seconds）Wake on wireless Transmit-Receive Unit, wireless transmit/receive units are started to work, that is, receive,
Send data；
7. if the wireless transmit/receive units receive the status data that other detection devices are sent（Including state change message, inspection
Survey unit exception status information）, then the wireless transmit/receive units status data received is sent to microprocessor, microprocessor
Wait for a period of time（Such as 3 seconds）, and be stored in the period and received whole status data, after the time expires, microprocessor is inscribed
Device wakes up cellular data unit, controls the cellular data unit that above-mentioned status data is sent to server, then microprocessor
Sleep signal is sent to cellular data unit, control cellular data unit enters resting state；
Further, microprocessor docks received status data and is judged, if having received multiple on same
The state change message of traffic safety facilities, then only lead to the state change message of last received traffic safety facilities
