It realizes 4 road analog inputs and 1 road analog output function.S7-200 is a kind of small-sized programmable controller, is fitted
For all trades and professions, the automation of detection, monitoring and control in various occasions.No matter the power of S7-200 series makes it
In independent operating, or it is connected to network and can all realizes complex control function.Therefore S7-200 series has high performance/valence
Lattice ratio.
Further, further include touch screen, the touch screen is connected with the Q1.0 of PLCS7-200 with the ends Q1.7.
Further, further include the camera being arranged before blocking bar, the camera is connected with PLCS7-200.
A kind of control method for alarm interceptor control system that bridge based on PLC is overweight, includes the following steps：
Step 1：Program starts and carries out system initialization；Check whether there is the input of freight weight limit parameter；If being not provided with limit
Weight parameter, then be defaulted as one day freight weight limit parameter；If so, then storing the freight weight limit parameter of input；Equal Wait Orders；Step 2：
When S type pull pressure sensor checks pressure signal, S types pull pressure sensor sends analog signal to EM235, and PLC passes through
The signal that EM235 is transmitted judges whether the freight weight limit parameter more than setting；If it exceeds freight weight limit parameter, carries out in next step；If no
Then terminate more than freight weight limit parameter；Step 3：The optoelectronic switch sensor has detected whether that vehicle passes through, if it is not, knot
Beam；If there is motor railing is put down, warning lamp is opened, and video camera is opened.
3, advantageous effect：
（1）This method has accurate, the service life using the signal of PLCS7-200 and S7-200 acquisition S type pull pressure sensor
It is long, the good advantage of interference.
（2）This method controls railing using stepper motor, and stepper motor is a kind of by electric pulse conversion angulation position
The drive device of shifting.Its performance stabilization compares and common electric machine precision height, and strong antijamming capability, and accuracy is high, does not have
More shakes.
（3）This method has monitored whether that vehicle passes through using optoelectronic switch sensor, has reflector installation environment not
It is limited；It is adjustable to be directed toward angle；It is longer than scattered reflection type detecting distance；The advantages that detectable heterogeneity.
