Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further illustrated.
As shown in Figure 1, the crossing input collector that GPRS module connects, comprise signal lamp 1 ... n, power switch 1, PLC controller 2, with connection terminal 9, power switch 1 connects PLC controller 2 provides system power supply, the voltage detection switch 7 connecting by connection terminal 9, its input termination signal lamp 1 ... n two ends measuring voltage, output connects the signal input part of PLC controller 2, tally circuit is through current transformer 10, be connected to current detection switch 8 by connection terminal 9, its output is connected to the signal input part of PLC controller 2, the output connection display unit 6 of PLC controller 2 is used for showing the state of current demand signal lamp.
Except using GPRS module 4 to divide into groups to transmit wireless data, by controlling software, following functions is also set:
Because input collector is arranged on crossing, not only environment for use is severe, and electromagnetic interference (EMI) is serious, and electronic equipment is broken down often.PLC controller is in the input sample stage, PLC reads in all input states and data successively with scan mode, and deposit them in I/O image area, proceeding to when carrying out user program and output and refreshing the stage, even if input state and data change, the state having deposited in I/O image area and data can not change, utilize this noiseproof feature of PLC, adopt ardware feature and the jamproof software measure of PLC controller, add strong anti-interference ability, mean free error time is reached more than tens thousand of hours, can be directly used in the scene of strong electromagnetic.
The attached signal lamp voltage signal detection figure that Figure 2 shows that, voltage detection switch 7 is made up of rectifier bridge D21, resistance R 21, resistance R 22, photoelectrical coupler Q21 and relay K 21.The input end of voltage detection switch 7 connects the tally circuit two ends of connection terminal 9, and the power supply using due to signal lamp has two kinds of AC and DCs, and with this, in Fig. 2, rectifier bridge D21 converts DC voltage to the unification of signal lamp voltage.R21 is current-limiting resistance, and Q21 is photoelectrical coupler, and K21 is relay, the collector current-limiting resistance that R22 is electric coupler.
In the time that signal lamp is lighted, rectifier bridge D21 output dc voltage makes the diode current flow of photoelectrical coupler Q21, by coupling, makes to be connected to the coil electricity of the relay K 21 on Q21 collector, and its contact adhesive is also connected to the signal input part of PLC controller.The duty of photoelectrical coupler Q21 is to be determined by the On current of the diode of its input, only has the collector of Q21 in the time that the diode current of its input reaches certain value just in conducting state.Therefore, just can reach by adjusting the resistance of current-limiting resistance R21 the corresponding relation of adjusting between signal lamp voltage and relay K 21 states.Thereby make testing circuit there is wider voltage adjusting range and also can eliminate the impact of interference voltage on relay K 21 states simultaneously.
The attached signal lamp current detecting figure that Figure 3 shows that, current detection switch 8 is made up of pickup coil L31, resistance R 31, rectifier bridge D31, resistance R 32, resistance R 33, triode Q31 and relay K 31.Measuring principle and voltage measurement are basic identical, and difference is that electric current is to be coupling on tally circuit and to be measured by current transformer 10.The input end of current detection switch 8 is by forming with tally circuit the pickup coil L31 being coupled and the resistance R 31 that is connected in parallel on pickup coil L31 two ends.In the time that signal lamp is lighted, in its branch road, have electric current to pass through, the resistance R 31 that is connected in parallel on current transformer two ends obtains voltage, adjusts R31 and can change its voltage.Rectifier bridge D31 output dc voltage, R32 is the base resistance of triode Q31, adjusts R32 with regard to its base current of capable of regulating, in the time that its electric current reaches certain value, the collector conducting of Q31, relay K 31 electric shock adhesives.
When signal lamp is normally worked, if signal lamp is illuminating state, voltage detection switch 7 and current detection switch 8 are all in attracting state; If signal lamp is to extinguish state, voltage detection switch 7 and current detection switch 8 are all in off-state; PLC controller 2, according to above information, sends to traffic control center the state of signal lamp by GPRS module 4.
When detecting device detects voltage detection switch 7 in attracting state and current detection switch 8 during all in off-state, show that signal lamp has damaged, PLC controller 2 can send failure message to traffic control center by GPRS module 4.
The basic configuration of this detecting device is 48 way switch amount inputs and the output of 48 way switch amounts, a signal lamp has two states of voltage and current, and therefore the state of 24 signal lamps of maximum detection amount, can meet the detection of general belisha beacon, in the time that signal lamp exceedes 24, expansion I/O module can be installed.
Specific works process is as follows: after start, enter system setting, comprise the setting of asynchronous communication mouth parameter.Carry out system detection simultaneously, comprise quantity and the state of signal lamp.After self check finishes, the signal of its input end is read in PLC controller 2 timing, and when a signal lamp is lighted, its state be (1,1), is (0,0) while extinguishing.PLC controller 2 is presented at this group signal condition in display unit 6 on the one hand, sends by GPRS module 4 to control center simultaneously.In the time that signal lamp breaks down, there will be signal lamp two ends to have voltage but situation that signal lamp does not work.Now, the input message that PLC controller 2 is read is (1,0), can demonstrate that this signal breaks down and send failure message to control center at display unit 6.
