Description

Technical Field

[0001] This invention relates to the field of construction, and more particularly to a load-bearing monitoring system for prefabricated buildings. Background Technology

[0002] Prefabricated buildings are becoming increasingly widespread due to their convenience, environmental friendliness, and savings in manpower and resources. However, compared to traditional buildings, prefabricated buildings require the assembly of various prefabricated components. During construction, the location of each prefabricated component, especially the prefabricated columns, and environmental factors can affect the load-bearing capacity of the prefabricated building. Currently, the testing of prefabricated buildings usually involves testing the performance and strength of each component to obtain the load-bearing capacity of the prefabricated building. However, it is not possible to monitor and alarm in real time during the construction process of prefabricated buildings to ensure construction safety.

[0003] Chinese patent CN110940501 B discloses a testing device and method for prefabricated buildings. Its technical feature is that the frame is fixed on the support, and the load-bearing beam is fixed on the frame through connectors. It can only test the performance of each component of the prefabricated building and cannot monitor it in real time. Summary of the Invention

[0004] To address this issue, the present invention provides a prefabricated building load-bearing monitoring system, which can solve the technical problem of not being able to judge the safety of prefabricated columns based on their offset and real-time environmental parameters, thereby enabling real-time monitoring and alarm of the load-bearing value of prefabricated buildings.

[0005] To achieve the above objectives, the present invention provides a prefabricated building load-bearing monitoring system, comprising: a data acquisition unit for acquiring real-time pressure of prefabricated slabs on prefabricated columns, the offset of prefabricated columns, and real-time environmental parameters, wherein the real-time environmental parameters include temperature, humidity, and wind speed; a first adjustment unit for adjusting a threshold standard value of the prefabricated column offset based on the height of the prefabricated column; a second adjustment unit connected to the first adjustment unit for determining the load-bearing weight of the prefabricated column based on the number of prefabricated components connected to the prefabricated column, and further adjusting the threshold standard value of the prefabricated column offset based on the load-bearing weight of the prefabricated column; and a judgment unit connected to the data acquisition unit. The monitoring unit, connected to the acquisition unit and the judgment unit respectively, is used to determine whether the precast column is in a safe state based on the real-time pressure it receives, and to further determine whether the precast column is in a safe state based on the real-time environmental impact obtained from real-time environmental parameters. It also obtains the building load-bearing value of the area where the precast column is located based on the proportion of vertical component connection nodes in the precast wall adjacent to the precast column that do not meet preset standards and the real-time offset of the precast column, and adjusts the threshold standard value of the precast column offset based on the building load-bearing value of the area.

[0006] Furthermore, the first adjustment unit adjusts the threshold standard value of the precast column offset based on the difference △h between the obtained height h of the precast column and the building design height H, and the preset height difference △H, setting △h = hH.

[0007] If △h≤△H1, the first adjustment unit determines the threshold standard value for increasing the precast column offset.

[0008] If △H1 < △h < △H2, the first adjustment unit will not adjust the threshold standard value of the precast column offset;

[0009] If △h≥△H2, the first adjustment unit determines the threshold standard value for reducing the precast column offset;

[0010] The first adjustment unit has a preset height difference value denoted as △H, a first preset height difference value of △H1, and a second preset height difference value of △H2.

[0011] Furthermore, when the height difference obtained by the first adjustment unit is less than or equal to the first preset height difference, the first adjustment unit increases the threshold standard value d of the precast column offset to d1, and sets d1 = d × (1 + |△H1 - △h| / △H1). When the height difference obtained by the first adjustment unit is greater than or equal to the second preset height difference, the first adjustment unit decreases the threshold standard value d of the precast column offset to d2, and sets d2 = d × (1 - |△H2 - △h| / △H2).

[0012] Furthermore, the second adjustment unit acquires the number n of precast components connected to the precast column, compares the acquired number n with a preset number N, and adjusts the load-bearing weight of the precast column.

[0013] If n≤N1, the second adjustment unit reduces the load-bearing weight q of the precast column to q1, and sets q1=q×(1-(|N1-n| / N1)). 1 / 2 );

[0014] If N1 < n < N2, the second adjustment unit will not adjust the load-bearing weight of the precast column;

[0015] If n≥N2, the second adjustment unit increases the load-bearing weight q of the precast column to q2, and sets q2=q×(1+(|N2-n| / N2)). 1 / 2 );

[0016] The second adjustment unit has a preset quantity N, and a first preset quantity N1 and a second preset quantity N2.

[0017] Furthermore, the second adjustment unit compares the load-bearing weight qi of the precast column with the preset load-bearing weight Q, and adjusts the threshold standard value of the precast column offset, wherein...

[0018] If qi≤Q, the second adjustment unit does not adjust the threshold standard value of the precast column offset;

[0019] If qi > Q, the second adjustment unit reduces the threshold standard value dj of the precast column offset to dj1, and sets dj1 = dj × (1-q / Q / 5);

[0020] Where i = 1, 2, j = 1, 2.

[0021] Further, the judgment unit acquires the real-time offset s of the precast column and compares the acquired real-time offset with the threshold standard value dj1 of the precast column offset to determine whether the position of the precast column meets the preset standard.

[0022] If s≤dj1, the judgment unit determines that the position of the precast column meets the preset standard;

[0023] If s > dj1, the judgment unit determines that the position of the precast column does not meet the preset standard and issues an alarm.

[0024] Furthermore, when the judgment unit determines that the position of the precast column meets the preset standard, the monitoring unit compares the real-time pressure f received by the precast column with the preset pressure F to determine whether the precast column is in a safe state.

[0025] If f≤F1, the monitoring unit determines that the precast column is in a safe state;

[0026] If F1 < f < F2, the monitoring unit initially determines that the precast column is not in a safe state, and obtains real-time environmental parameters to further determine whether the precast column is in a safe state;

[0027] If f≥F2, the monitoring unit determines that the precast column is in a dangerous state and issues an alarm;

[0028] The preset pressure is denoted as F, the first preset pressure is set as F1, and the second preset pressure is set as F2.

[0029] Furthermore, when the real-time pressure on the precast column obtained by the monitoring unit is greater than the first preset pressure but less than the second preset pressure, the monitoring unit obtains the real-time environmental impact degree r based on the real-time environmental parameters, setting r = (t / T0×Z1) + (p / PO×Z2) + (v / VO×Z3), where t is the real-time temperature, T0 is the preset temperature standard value, p is the real-time humidity, P0 is the preset humidity standard value, v is the real-time wind speed, and VO is the preset wind speed standard value. The monitoring unit presets a first adjustment coefficient Z1, a second adjustment coefficient Z2, and a third adjustment coefficient Z3. The monitoring unit compares the obtained environmental impact degree with the preset environmental impact degree R to further determine whether the precast column is in a safe state.

[0030] If r≤R, the monitoring unit determines that the precast column is in a dangerous state and issues an alarm;

[0031] If r > R, the monitoring unit determines that the precast column is in a safe state.

[0032] Furthermore, when the monitoring unit determines that the precast column is in a safe state, the monitoring unit obtains the load-bearing value w of the building in the area where the precast column is located based on the proportion k of the number of vertical component connection nodes that do not meet the preset standard in the adjacent precast wall and the real-time offset s of the precast column. The value w is set to w = (k / K) × (s / S), where K is the preset standard value for the proportion of vertical components and S is the preset standard value for the offset. The monitoring unit compares the obtained load-bearing value w of the building in the area where the precast column is located with the preset load-bearing value W to determine whether the load-bearing value of the building in the area where the precast column is located meets the preset standard.

[0033] If w≤W, the monitoring unit determines that the load-bearing capacity of the building in the area where the precast column is located meets the preset standard;

[0034] If w > W, the monitoring unit determines that the load-bearing capacity of the building in the area where the precast column is located does not meet the preset standard.

[0035] Furthermore, when the building load-bearing value obtained by the monitoring unit is greater than the preset load-bearing value, the monitoring unit determines the threshold standard value di 1 to di 1' for reducing the offset of the precast column, and sets di 1' = di 1 × (1 - |Ww| / W / 2).

[0036] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention is equipped with a first adjustment unit, which can adjust the threshold standard value of the precast column offset according to the height of the precast column; the second adjustment unit determines the load-bearing weight of the precast column according to the number of precast components connected to the precast column, and adjusts the threshold standard value of the precast column offset a second time according to the obtained load-bearing weight; the judgment unit compares the real-time offset of the precast column with the threshold standard value of the precast column offset, and issues an alarm when the real-time offset of the precast column exceeds the preset standard, thereby realizing real-time monitoring of the position of each precast column; when the real-time offset of the precast column meets the preset standard, the monitoring unit adjusts the threshold standard value of the precast column offset according to the real-time offset of the precast column. The pressure applied to the precast column is used to assess its safety. When the real-time pressure on the precast column does not meet the preset standard, the real-time environmental impact is obtained based on real-time environmental parameters. The detection unit compares the obtained real-time environmental impact with the preset impact to further assess the safety of the precast column. When the safety of the precast column meets the preset standard, the load-bearing capacity of the building in the area where the precast column is located is obtained based on the proportion of vertical component connection nodes in the adjacent precast wall that do not meet the preset standard and the real-time offset of the precast column. When the obtained load-bearing capacity of the building in the area where the precast column is located does not meet the preset standard, the monitoring unit adjusts the threshold standard value of the precast column offset, thereby ensuring that the load-bearing capacity of the prefabricated building meets the preset standard. This invention achieves real-time monitoring of the load-bearing capacity of prefabricated buildings by real-time monitoring of the offset and safety of precast columns and issuing alarms, thus ensuring construction safety during the construction of prefabricated buildings.

[0037] In particular, when the height difference obtained by the first adjustment unit is less than or equal to the first preset height difference, it indicates that the precast column is at a relatively high height, needs to bear less pressure, and has lower requirements for the position of the precast column. In order to improve construction efficiency and avoid frequent alarms, the first adjustment unit increases the threshold standard value of the precast column offset. When the height difference obtained by the first adjustment unit is greater than or equal to the second preset height difference, it indicates that the precast column is at a relatively low height, is subjected to greater pressure, and has a greater impact on the building's load-bearing capacity. Therefore, the first adjustment unit decreases the threshold standard value of the precast column offset.

[0038] In particular, the more precast components connected to the precast column, the more important the precast column is, the greater its impact on the building's load-bearing capacity, and the higher the requirements for the position of the precast column. Therefore, the second adjustment unit adjusts the load-bearing weight of the precast column according to the number of precast components connected to the precast column, and compares the obtained load-bearing weight of the precast column with the preset load-bearing weight to perform a secondary adjustment on the threshold standard value of the precast column offset.

[0039] In particular, when the real-time offset of the precast column exceeds the threshold standard value for precast column offset, it indicates that the offset of the precast column is so large that it will affect the construction of the building. The judgment unit issues an alarm. When the position of the precast column meets the preset standard, the monitoring unit compares the real-time pressure on the precast column with the preset pressure. When the real-time pressure on the precast column is less than or equal to the first preset pressure, the precast column can withstand the load without affecting the building's load-bearing capacity. Therefore, the monitoring unit determines that the safety of the precast column meets the preset standard. The environment will affect the pressure on the precast column. Therefore, when the pressure on the precast column is greater than the first preset pressure but less than the second preset pressure, the safety of the precast column needs to be further judged. When the pressure on the precast column is greater than or equal to the second preset pressure, the pressure on the precast column exceeds the bearing capacity, and an alarm is issued.

[0040] In particular, the monitoring unit obtains the real-time environmental impact degree based on real-time environmental parameters and compares the obtained real-time environmental impact degree with the preset environmental impact degree. When the real-time environmental impact degree obtained by the monitoring unit is less than or equal to the preset environmental impact degree, it indicates that the environment has little impact on the real-time pressure on the precast column, thus eliminating environmental interference. The pressure on the precast column exceeds the safe range, and the monitoring unit determines that the safety of the precast column does not meet the preset standard and issues an alarm. When the real-time environmental impact degree obtained by the monitoring unit is greater than the preset environmental impact degree, it indicates that environmental interference has been eliminated, and the precast column can withstand the pressure. The monitoring unit determines that the safety of the precast column meets the preset standard.

[0041] In particular, the monitoring unit obtains the load-bearing value of the building in the area where the precast column is located based on the proportion of vertical component connection nodes that meet the preset standards in the adjacent precast walls and the real-time offset of the precast column. When the load-bearing value of the building obtained by the monitoring unit is greater than the preset standard, the offset of the precast column is large, and the proportion of vertical component connection nodes that do not meet the preset standards in the adjacent precast walls is large, which leads to the load-bearing value of the building in the area where the precast column is located not meeting the preset standard. In order to ensure the load-bearing value of the building, the monitoring unit determines the threshold for reducing the offset of the precast column, thereby ensuring that the load-bearing value of the building meets the preset standard by controlling the safety of the precast column.

[0048] Please see Figure 1 As shown, it is a schematic diagram of the prefabricated building load-bearing monitoring system according to an embodiment of the present invention, including,

[0049] The data acquisition unit is used to collect real-time pressure of the precast slab on the precast column, the offset of the precast column, and real-time environmental parameters, including temperature, humidity, and wind speed.

[0050] The first adjustment unit is used to adjust the threshold standard value of the precast column offset according to the height of the precast column;

[0051] The second adjustment unit, which is connected to the first adjustment unit, is used to determine the load-bearing weight of the precast column based on the number of precast components connected to the precast column, and to perform secondary adjustment on the threshold standard value of the precast column offset based on the load-bearing weight of the precast column.

[0052] The judgment unit, which is connected to the acquisition unit, is used to judge the standardity of the position of the precast component based on the real-time offset of the precast column.

[0053] The monitoring unit, which is connected to the acquisition unit and the judgment unit respectively, is used to judge whether the precast column is in a safe state based on the real-time pressure it receives, and to further judge whether the precast column is in a safe state based on the real-time environmental impact obtained from real-time environmental parameters. It also uses the ratio of vertical component connection nodes in the precast wall adjacent to the precast column that do not meet preset standards and the real-time offset of the precast column to obtain the building load-bearing value of the area where the precast column is located, and adjusts the threshold standard value of the precast column offset based on the building load-bearing value of the area.

[0054] Please see Figure 2 As shown, it is a schematic diagram of a prefabricated building area according to an embodiment of the present invention, including,

[0055] The precast column 1, the precast slab 2 set above the precast column, the pressure sensor 3 used to detect the real-time pressure on the precast column, and the precast wall 4 adjacent to the precast column.

[0056] The first adjustment unit adjusts the threshold standard value of the precast column offset based on the difference △h between the height h of the precast column and the building design height H, and the preset height difference △H, setting △h = hH.

[0057] If △h≤△H1, the first adjustment unit determines the threshold standard value for increasing the precast column offset.

[0058] If △H1 < △h < △H2, the first adjustment unit will not adjust the threshold standard value of the precast column offset;

[0059] If △h≥△H2, the first adjustment unit determines the threshold standard value for reducing the precast column offset;

[0060] The first adjustment unit has a preset height difference value denoted as △H, a first preset height difference value of △H1, and a second preset height difference value of △H2.

[0061] When the height difference obtained by the first adjustment unit is less than or equal to the first preset height difference, the first adjustment unit increases the threshold standard value d of the precast column offset to d1, and sets d1 = d × (1 + |△H1 - △h| / △H1). When the height difference obtained by the first adjustment unit is greater than or equal to the second preset height difference, the first adjustment unit decreases the threshold standard value d of the precast column offset to d2, and sets d2 = d × (1 - |△H2 - △h| / △H2).

[0062] Specifically, when the height difference obtained by the first adjustment unit is less than or equal to the first preset height difference, it indicates that the precast column is at a relatively high height, needs to bear less pressure, and has lower requirements for the position of the precast column. In order to improve construction efficiency and avoid frequent alarms, the first adjustment unit increases the threshold standard value of the precast column offset. When the height difference obtained by the first adjustment unit is greater than or equal to the second preset height difference, it indicates that the precast column is at a relatively low height, is subjected to greater pressure, and has a greater impact on the building's load-bearing capacity. Therefore, the first adjustment unit decreases the threshold standard value of the precast column offset.

[0063] The second adjustment unit acquires the number n of precast components connected to the precast column, compares the acquired number n with a preset number N, and adjusts the load-bearing weight of the precast column accordingly.

[0064] If n≤N1, the second adjustment unit reduces the load-bearing weight q of the precast column to q1, and sets q1=q×(1-(|N1-n| / N1)). 1 / 2 );

[0065] If N1 < n < N2, the second adjustment unit will not adjust the load-bearing weight of the precast column;

[0066] If n≥N2, the second adjustment unit increases the load-bearing weight q of the precast column to q2, and sets q2=q×(1+(|N2-n| / N2)). 1 / 2 );

[0067] The second adjustment unit has a preset quantity N, and a first preset quantity N1 and a second preset quantity N2.

[0068] The second adjustment unit compares the load-bearing weight qi of the precast column with the preset load-bearing weight Q, and adjusts the threshold standard value of the precast column offset.

[0069] If qi≤Q, the second adjustment unit does not adjust the threshold standard value of the precast column offset;

[0070] If qi > Q, the second adjustment unit reduces the threshold standard value dj of the precast column offset to dj1, and sets dj1 = dj × (1-q / Q / 5);

[0071] Where i = 1, 2, j = 1, 2.

[0072] Specifically, the more precast components connected to the precast column, the more important the precast column is, the greater its impact on the building's load-bearing capacity, and the higher the requirements for the position of the precast column. Therefore, the second adjustment unit adjusts the load-bearing weight of the precast column according to the number of precast components connected to the precast column, and compares the obtained load-bearing weight of the precast column with the preset load-bearing weight to make a secondary adjustment to the threshold standard value of the precast column offset.

[0073] The judgment unit acquires the real-time offset s of the precast column and compares the acquired real-time offset with the threshold standard value dj1 of the precast column offset to determine whether the position of the precast column meets the preset standard.

[0074] If s≤dj1, the judgment unit determines that the position of the precast column meets the preset standard;

[0075] If s > dj1, the judgment unit determines that the position of the precast column does not meet the preset standard and issues an alarm.

[0076] When the judgment unit determines that the position of the precast column meets the preset standard, the monitoring unit compares the real-time pressure f on the precast column with the preset pressure F to determine whether the precast column is in a safe state.

[0077] If f≤F1, the monitoring unit determines that the precast column is in a safe state;

[0078] If F1 < f < F2, the monitoring unit initially determines that the precast column is not in a safe state, and obtains real-time environmental parameters to further determine whether the precast column is in a safe state;

[0079] If f≥F2, the monitoring unit determines that the precast column is in a dangerous state and issues an alarm;

[0080] The preset pressure is denoted as F, the first preset pressure is set as F1, and the second preset pressure is set as F2.

[0081] Specifically, when the real-time offset of the precast column exceeds the threshold standard value for precast column offset, it indicates that the offset of the precast column is so large that it will affect the construction of the building, and the judgment unit issues an alarm. When the position of the precast column meets the preset standard, the monitoring unit compares the real-time pressure on the precast column with the preset pressure. When the real-time pressure on the precast column is less than or equal to the first preset pressure, the precast column can withstand the load without affecting the building's load-bearing capacity, so the monitoring unit determines that the safety of the precast column meets the preset standard. The environment will affect the pressure on the precast column, so when the pressure on the precast column is greater than the first preset pressure but less than the second preset pressure, the safety of the precast column needs to be further judged. When the pressure on the precast column is greater than or equal to the second preset pressure, the pressure on the precast column exceeds the bearing capacity, and an alarm is issued.

[0082] When the real-time pressure on the precast column, as obtained by the monitoring unit, is greater than a first preset pressure but less than a second preset pressure, the monitoring unit obtains the real-time environmental impact degree *r* based on real-time environmental parameters. *r* is set as: (t / T0×Z1) + (p / PO×Z2) + (v / VO×Z3), where t is the real-time temperature, T0 is the preset temperature standard value, p is the real-time humidity, P0 is the preset humidity standard value, v is the real-time wind speed, and VO is the preset wind speed standard value. The monitoring unit presets a first adjustment coefficient Z1, a second adjustment coefficient Z2, and a third adjustment coefficient Z3. The monitoring unit compares the obtained environmental impact degree with the preset environmental impact degree *R* to further determine whether the precast column is in a safe state.

[0083] If r≤R, the monitoring unit determines that the precast column is in a dangerous state and issues an alarm;

[0084] If r > R, the monitoring unit determines that the precast column is in a safe state.

[0085] Specifically, the present invention does not impose specific limitations on the adjustment coefficients. The present invention provides a preferred embodiment in which Z1 = 0.6-0.8, Z2 = 0.4-0.6, and Z3 = 1.2-1.4.

[0086] Specifically, the monitoring unit obtains the real-time environmental impact degree based on real-time environmental parameters and compares the obtained real-time environmental impact degree with the preset environmental impact degree. When the real-time environmental impact degree obtained by the monitoring unit is less than or equal to the preset environmental impact degree, it indicates that the environment has little impact on the real-time pressure on the precast column, thus eliminating environmental interference. The pressure on the precast column exceeds the safe range, and the monitoring unit determines that the safety of the precast column does not meet the preset standard and issues an alarm. When the real-time environmental impact degree obtained by the monitoring unit is greater than the preset environmental impact degree, it indicates that environmental interference has been eliminated, and the precast column can withstand the pressure. The monitoring unit determines that the safety of the precast column meets the preset standard.

[0087] When the monitoring unit determines that the precast column is in a safe state, it obtains the load-bearing value w of the building in the area where the precast column is located based on the proportion k of vertical component connection nodes that do not meet the preset standard within the adjacent precast wall and the real-time offset s of the precast column. The value w is set as (k / K) × (s / S), where K is the preset standard value for the proportion of vertical components and S is the preset standard value for the offset. The monitoring unit compares the obtained load-bearing value w of the building in the area where the precast column is located with the preset load-bearing value W to determine whether the load-bearing value of the building in the area where the precast column is located meets the preset standard.

[0088] If w≤W, the monitoring unit determines that the load-bearing capacity of the building in the area where the precast column is located meets the preset standard;

[0089] If w > W, the monitoring unit determines that the load-bearing capacity of the building in the area where the precast column is located does not meet the preset standard.

[0090] When the building load-bearing value obtained by the monitoring unit is greater than the preset load-bearing value, the monitoring unit determines the threshold standard value di 1 to di 1' for reducing the offset of the precast column, and sets di 1' = di 1 × (1 - |Ww| / W / 2).

[0091] Specifically, this invention does not specifically limit the method for obtaining the proportion of vertical component connection nodes in the precast wall adjacent to the precast column that do not meet the preset standards. An embodiment of this invention provides a preferred implementation scheme in which an X-ray machine emits X-rays to the vertical component connection nodes of the precast wall, a wireless portable digital X-ray imaging system receives the X-rays and converts them into an internal structural diagram of the wall, and transmits them wirelessly to a PDA for imaging. The monitoring unit observes the specific situation of the vertical component connection nodes in the wall on the screen of the PDA, and obtains the total number of vertical component nodes in the precast wall and the number of vertical component nodes that do not meet the preset standards, thereby obtaining the proportion of vertical component connection nodes in the precast wall adjacent to the precast column that do not meet the preset standards.

[0092] Specifically, the monitoring unit obtains the load-bearing value of the building in the area where the precast column is located based on the proportion of vertical component connection nodes that meet the preset standards in the adjacent precast walls and the real-time offset of the precast column. When the building load-bearing value obtained by the monitoring unit is greater than the preset standard, the offset of the precast column is large, and the proportion of vertical component connection nodes that do not meet the preset standards in the adjacent precast walls is large, which leads to the building load-bearing value in the area where the precast column is located not meeting the preset standard. In order to ensure the building load-bearing value, the monitoring unit determines the threshold for reducing the offset of the precast column, thereby ensuring that the building load-bearing value meets the preset standard by controlling the safety of the precast column.

[0093] Specifically, this invention does not limit the specific implementation of the prefabricated building load-bearing monitoring system. One preferred embodiment is provided whereby the first adjustment unit obtains a difference of 6m between the height of the prefabricated column (9m) and the designed building height (15m). The first adjustment unit compares this height difference (5m) with a first preset height of 5m and a second preset height of 8m, and determines that no adjustment will be made to the threshold standard value of 10cm for the prefabricated column offset. The second adjustment unit compares the number of prefabricated components connected to the prefabricated column (5) with a first preset number of 2 and a second preset number of 4, and increases the load-bearing weight of the prefabricated column (6) to 3×(1+(|4-5| / 4)). 1 / 2= 6.7. The second adjustment unit compares the precast column's load-bearing weight of 6.7 with the preset load-bearing weight of 8, and determines that no adjustment should be made to the threshold standard value of 10cm for the precast column's offset. The judgment unit compares the obtained real-time offset of 8cm of the precast column with the threshold standard value, and determines that the position of the precast column meets the preset standard. The monitoring unit determines and obtains real-time environmental parameters based on the real-time pressure of 800N, the first preset pressure of 500N, and the second preset pressure of 1000N on the precast column. The monitoring unit obtains the real-time environmental impact degree (20℃ / 23℃×0.6)+(37% / 55%×0.5)+(12m / s / 10) based on the real-time temperature of 20℃, the preset temperature standard value of 23℃, the real-time humidity of 37%, the preset humidity standard value of 55%, the real-time wind speed of 12m / s, and the preset wind speed standard value of 10m / s. The monitoring unit compares the real-time environmental impact value of 2.5 with the preset environmental impact value of 2 to determine that the safety of the precast column meets the preset standard. Based on the number of vertical component connection nodes in the precast wall adjacent to the precast column (140) and the number of vertical component connection nodes that do not meet the preset standard (20), the monitoring unit obtains the proportion of vertical component connection nodes that do not meet the preset standard (20 / 140 = 14%). The monitoring unit uses the obtained proportion of 14%, the real-time offset of the precast column (8cm), the preset proportion of 20%, and the preset standard value of offset (5cm) to obtain the load-bearing value of the building in the area where the precast column is located (14% / 20%) × (5cm / 8cm) = 0.44, which is less than the preset load-bearing value of 0.5. Therefore, the monitoring unit determines that the load-bearing value of the building in the area where the precast column is located meets the preset standard.
