And the display interface of the background management PC can simultaneously display the pressure data monitored by the monitoring point positions.
As shown in fig. 1, 2 and 3, before the invention is used, a set of scaffold support pressure detection system (such as an uneven ground area and an area with poor ground geological conditions) is installed at a plurality of key monitoring point locations in a construction area and each point location. After the upper end support plate 21 of the scaffold 3 at the installation point and the support of the support frame plate at the lower end of the template are contacted to form support, the power switch SK is turned on, then, the power output by the storage battery G enters the power input ends of the GPRG module U3, the single chip microcomputer module U2, the plane pressure sensor U1 and the alarm circuit, and the GPRG module U3, the single chip microcomputer module U2 and the plane pressure sensor U1 are in a power-on working state. In the alarm circuit, after the lower end of the support frame plate is fully contacted with the two sides of the upper end of the pressure sensor U1 and the upper ends of the buttons of the two micro switches S1 and S2, the internal contacts of the two micro switches S1 and S2 are in a closed state, so that the positive pole of a 12V power supply can be subjected to voltage reduction and current limitation through the two micro switches S1 and S2 and a resistor R1 to enter the base electrode of an NPN triode Q1, and the base electrode of the NPN triode Q1 is subjected to proper bias conduction; and then, the collector of the alarm device outputs a low level to enter the base of an NPN triode Q2, the base of an NPN triode Q2 is in a cut-off state without proper forward bias, the collector of the alarm device does not output a low level to enter the negative power input end of the alarm device B, the alarm device B does not sound, the scaffold representing the monitoring point is effectively contacted with the lower end of the support frame plate of the template support point, and the installation in place is prompted. In the alarm circuit, when the support is formed by the upper end support plate 21 of the installation point position scaffold and the lower end of the support frame plate at the lower part of the template without contact, and the buttons of the two power switches S1 and S2 are not pressed, or the button for supporting one of the power switches S1 or S2 is formed at only one side end and is not pressed at the internal contact thereof for opening the circuit, the anode of the 12V power supply can not be subjected to voltage reduction and current limitation through the resistor R1 and enters the base electrode of the NPN triode Q1; the base electrode of the NPN triode Q1 is cut off, no level of the collector electrode of the NPN triode Q1 enters the base electrode of the NPN triode Q2, the base electrode of the NPN triode Q2 is subjected to voltage reduction and current limiting through the resistor R2, proper forward bias voltage conduction is obtained from the 12V power supply positive electrode, then the low level of the collector electrode output enters the negative power supply input end of the buzzer B, the buzzer B is electrified to make a sounding prompt sound, and an installer is prompted that the scaffold is not installed in place, namely, the upper end support plate 21 of the scaffold 3 at the installation site and the lower end support frame plate of the template are not in contact with each other to form effective support, so that the installer can adjust the position between the scaffold and the support frame plate in time, the scaffold and the scaffold are guaranteed to be.
As shown in fig. 1, 2 and 3, in the invention, when the pressure sensor U1 works, the weight of the formwork and the poured concrete directly acts on the upper supporting surface thereof, and as the weight is different (the maximum measured weight can reach 30 tons, and the output current of more than 30 tons is fixed at 20MA), 3 pins of the pressure sensor U1 can output weight analog current signals which are changed between 4 and 20MA dynamically to 3 pins of the single chip module U2; under the action of an internal circuit of the singlechip module U2, the dynamically changed analog current signal is converted into a dynamically changed digital signal, and the dynamically changed digital signal is transmitted out through a GPRS module U3 through a wireless mobile network. After the PC receiving unit of the construction department management background receives the dynamic change data uploaded by the monitoring point GPRS modules U3, the dynamic change data are output to the data processing unit. The data processing unit processes the input multi-channel data and outputs the processed data to the comparison unit, and the comparison unit can automatically call the data in the database unit for comparison to obtain whether the upper end support plate of the scaffold and the lower end support frame plate of the template contact to form effective support. In application, for example, when a scaffold independently supports a template, the number stored in the database unit and displayed by the PC display screen is 2 (or displayed by a oscillogram and the like); when the scaffold independently supports the template and pours concrete with a certain thickness, the number stored in the database unit and displayed by the PC display screen is 8 (or displayed by a oscillogram and the like, and the display screen displays data of a plurality of monitoring points in a split screen manner); however, if the input data is far less than 2 or 8 (displayed on a screen of a PC and displaying the position of a specific fault point), the comparison unit judges that the scaffold is incorrectly supported, and when the support is unqualified (for example, the support cannot be supported because the ground is collapsed or the steel pipe joints between a plurality of scaffolds are not fixed tightly, the support frame plate between the upper end support plate of the scaffold for supporting and supporting the frame plate and the lower part of the template is pulled away from the gap), an alarm signal is generated through the data output unit. If the input data is close to or larger than 2 or 8, the comparison unit judges that the scaffold is correctly supported and does not generate an alarm signal. Therefore, after a background monitoring person observes that the scaffold support in a certain area is unqualified through a screen, the background monitoring person can timely inform relevant persons to go to the site for maintenance, the data output unit can also push short messages for the mobile phones of the relevant persons, and after the mobile phones of the relevant persons receive the short messages (the short messages have fault point position prompts), the mobile phones of the relevant persons can timely go to the site for fault discharge, so that the construction quality is guaranteed, and the probability that the persons are injured is reduced.
