Degree is 56%.Wherein 1 indicate that temperature is negative value.
Cell voltage indicates the voltage value for the battery that Power Management Unit detects.Such as 1234 expression cell voltage be
12.34V。
1 Iron tower incline monitoring device data transmission format of table
Wherein the definition of error code is as shown in Fig. 3.
Error code totally 16, each can represent an abnormality.When abnormality occurs, if being abnormal
Then according to unusual condition by the abnormal position 1 of corresponding positions, it is 0 that response bit, which is otherwise arranged,.When error code is simply by the presence of 1, then table
Show that there are warning messages in error code.It should be noted that intelligent control host, which is taken, first detects the abnormal original first alarmed
It then, can be successively by corresponding position 1 so after the alarm of multiple exception-triggereds.
After triggering alarm, Iron tower incline detection device is included in automatically reports mode.And if only if abnormal releasing, can just move back
Mode is reported out.Maloperation in order to prevent, abnormal release only are released by following two method:
A) alarm threshold value is reset；
B) physical quantity alarmed is restored within threshold range.
On the other hand, in order to realize control of the power scheduling computer room to Iron tower incline detection device, power scheduling computer room is also
Big Dipper short message being sent by Beidou transmission terminal and giving Iron tower incline detection device, the threshold value or threshold value model of sensor are set
It encloses.If the numerical value detected exceeds the setting value or range, Iron tower incline detection device will be alarmed by Beidou transmission terminal
Information is sent to power scheduling computer room.
Table 2 describes Iron tower incline monitoring device alarm threshold value setting format, by electric power tune in the form of Big Dipper short message
Degree computer room is sent to the threshold value setting information of Iron tower incline monitoring device.Include in the format: authentication code, prefix, order mark
The information such as code, threshold tipping value, temperature threshold, humidity threshold, battery voltage threshold and check code.
Wherein, the length of authentication code is 2 bytes；The length of prefix, order identity code and check code is 1 byte；Humidity
The length of threshold value and battery voltage threshold is 2 bytes；The length of threshold tipping value is 12 bytes.
Format is arranged in 2 Iron tower incline monitoring device alarm threshold value of table
Threshold tipping value is made of the threshold value connection of two inclination sensors, and the threshold value of each sensor is M ± X.xxx, and N ±
Y.yyy, Q ± Z.zzz.It is wherein after intelligent control host receives this instruction, to be sensed according to inclination with reference to angle M, N, Q
Device calculated average value of collected three axis (i.e. X-axis, Y-axis, Z axis) data within 5 second time.
Temperature threshold is a temperature range, if the temperature that temperature sensor detects sends alarm beyond the range
Information.Such as SLLtSHHt=1200 0506, expression temperature range are -20 DEG C < T < 50.6 DEG C.
Humidity threshold is that a humidity range if the humidity that humidity sensor detects has exceeded the range sends police
It notifies breath.For example, RLRH=2080 indicates that humidity range is 20%~80%.
Battery voltage threshold is a voltage range, if the voltage value that Power Management Unit detects has exceeded the range,
Then send warning information.For example, VLvvVHvv=11001350 indicates voltage range in 11.00V~13.05V.
Power scheduling computer room receive Iron tower incline monitoring device transmission Big Dipper short message after, to Big Dipper short message into
Row parsing, the content transmission parsed is shown into monitoring management system；If mobile network can also be passed through comprising warning message
Warning message is sent to administrative staff by the operator base station of network, notifies maintenance personnel to the steel tower being abnormal by administrative staff
Place is safeguarded by steel tower and Iron tower incline monitoring device.
Maintenance personnel can be configured threshold data by Bluetooth control unit, and intelligent control host can be automatic at this time
The threshold value of setting is sent to power scheduling computer room by Beidou transmission terminal and is given a warning, power scheduling computer room can be timely
It obtains threshold value setting and changes situation.Threshold value can be reasonably arranged according to the situation at steel tower scene in maintenance personnel in this way, can also be with
Although the fault for avoiding maintenance personnel's threshold value from being arranged causes to monitor steel tower data, can not be timely to potential risks
The case where acquisition.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and replacement can also be made, these are improved and replacement
Also it should be regarded as protection scope of the present invention.
