Embodiment
The functional block diagram of " polymorphic type sensor general-purpose interface " described in the utility model as shown in Figure 1.It comprises following a few part: sensor power pack 101, and the working sensor power supply is confessed thus; Sensor output signal part 102 enters interface thus from the signal of sensor; Sensor type coded portion 103 is realized the coding to sensor type; Working sensor state indicating section 104, by the LED indication, the user can see current working state, alarm situation intuitively.
Accompanying drawing 2 is embodiments of polymorphic type sensor general-purpose interface:
Selection for interface socket: by to after the factor analyses such as the function of various sockets, performance, volume, price, versatility, the selected Registered Jack-45 of the utility model is as the interface of sensor.Registered Jack-45 not only can satisfy the requirement to number of pins, also has two LED, can show current working state, alarm situation etc. intuitively to the user.In 8 lead-in wires of Registered Jack-45, two power supplies that are used for sensor interface, i.e. power lead, ground wire; Two are used to introduce signal of sensor; Other four are used for the type of sensor coding.
For the power supply power pack: through at present in the observing and controlling of large-scale communication machine room environment employed sensor model number analyze, conclude as can be known, its operating voltage generally has three kinds :+5V ,+12V ,+24V.Therefore, require interface 203 that three kinds of operating voltage can be provided.We arrange a power lead in interface 203, interface is not outwards power supply at ordinary times, has only after sensor is on the throne, when right judgement goes out sensor type, just can control power supply selector switch 204, outwards confess operating voltage, to satisfy the requirement of dissimilar sensor operating voltage.
For signal processing: because the difference of operating voltage, signal of sensor also has different level, causes sensor output signal can not directly give FPGA and handles.For this reason, we have adopted optocoupler 205, sensor output signal under the various different operating voltages become give FPGA after the unified digital signal and handle, accomplished effective isolation of sensor output signal and FPGA, FPGA can both be handled the output signal of dissimilar sensor under the different operating voltage.Owing to adopted optocoupler 205 to isolate, interface 203 requires the output of sensor to should be level signal or square-wave signal.The signal of sensor line generally is 1～2 the tunnel, so is provided with two sensor input signal lines in the interface 203.
For coded portion: adopt four lines of codes to realize type of sensor is encoded.In design, for the sensor type of the required support of measuring and controlling equipment, unique encoding of the sensor assignment of each type.When the connecting line of processing and fabricating sensor and interface, should set the connection status of respective coding line according to each type of sensor coding.Implementation for coding can have multiplely, can select for use according to actual conditions in application.
State-detection and power supply control for polymorphic type sensor general-purpose interface, can realize by the TT﹠C software of writing CPU, when the access that sensor is arranged in the interface or when extracting, FPGA detects sensor type line of codes state and changes, interrupt to the CPU application, in interrupt service routine, the CPU TT﹠C software just can be judged state in front port by the inquiry line of codes, if sensor is not on the throne or the sensor type nonrecognition, then stop power supply, if the sensor type for having set then provides corresponding power supply to it, by the output signal of FPGA processes sensor, more current state is given the CPU TT﹠C software to handle then.
Fig. 3 is the process flow diagram of CPU TT﹠C software part, has only described the interrupt service routine when TT﹠C software is handled an interface herein, comprising:
Step 31 is closed and is interrupted;
Step 32 had sensor on the throne in the interface? be, carry out 33, do not carry out 34;
Step 33 stops to turn to 36 to the interface power supply;
Are step 34, type coding the known sensor type? be, carry out 35, do not carry out 33;
Step 35 is powered to interface according to sensor type;
Step 36 is opened interruption;
Step 37 is returned.
Interrupt service routine when more than being an interface.If when a plurality of interface was arranged, interrupt service routine should be handled the state of a plurality of interfaces.
Fig. 4 is an embodiment of power supply selector switch.Can use 3 relays to realize the selection of power supply, the control of relay is responsible for by FPGA, the control end 411,421,431 of relay 41,42,43 all is connected with FPGA, change the state of these 3 relays by FPGA, can outwards confess+5V ,+12V ,+three kinds of different power supplys of 24V.Wherein N.C. represents not have connection, and to be implemented under the no sensor situation on the throne, interface is outwards power supply.
