Embodiment

With reference to shown in Fig. 1 to Fig. 4, the utility model is described in further detail.

As shown in figure 1, present embodiment discloses a kind of node type seismic prospecting instrument of real-time monitoring wave detector state, bag Main control chip 10, at least one wave detector voltage collection circuit 20 and indicator lamp 30 are included, main control chip 10 is adopted with wave detector voltage The connection of collector 20 carries out two-way communication, is connected with the indicator lamp 30 of wave detector state.

Specifically, the port of main control chip 10 can be set as various functions in the present embodiment, with undertake Enable Pin with Output end function.The port that wherein main control chip 10 is connected with wave detector voltage collection circuit 20 is with the work for being enable port There is the function of output end with, the port that is connected with indicator lamp 30.

It should be noted that the quantity of the indicator lamp 30 of the wave detector state and the number phase of wave detector voltage detecting circuit Together, and for reddish yellow bi-colour light, when the incoming end of wave detector is normally accessed, indicator lamp does not light.When the incoming end of wave detector is During open-circuit condition, indicator lamp glows.When wave detector incoming end is short-circuit condition, indicator lamp Yellow light-emitting low temperature.

Specifically, wave detector voltage collection circuit 20 includes A/D conversion chips 21, current source 22, the and of current supply switch 23 First, second pull down resistor 24,25;

Main control chip 10 is connected progress two-way communication with A/D conversion chips 21;

The analog signal output of wave detector interface is connected by signal wire with the input of A/D conversion chips 21, detection The analog signal output of device interface is also connected by current supply switch 23 with current source 22;

The analog signal output of wave detector interface is grounded after being connected respectively with first, second pull down resistor 24,25.

Closed it should be noted that the output of main control chip 10 enables signal control electric current source switch 23, make current source 22 with Wave detector interface is connected, and the electric current that certain value is just had in wave detector flows through, and the state of wave detector incoming end is different, wave detector The voltage at two ends is different.Main control chip 10, which can be sent, enables the voltage that signal control A/D conversion chips 21 gather wave detector two ends, The magnitude of voltage that main control chip 10 is collected according to A/D conversion chips 21, judges the state of wave detector incoming end.

According to wave detector both end voltage value judge that the concrete principle of the state of wave detector incoming end is as follows:

When wave detector is normally accessed, if current supply switch 23 is closed, the electric current of current source 22 can be through wave detector interface After wave detector and first, second pull down resistor 24,25, then flow to ground.It is assumed here that first, second pull down resistor 24th, 25 resistance value is R0, the value of wave detector DC internal resistance is R1, the current value of current source 22 is i0, when the input of wave detector During normal access circuit, the magnitude of voltage at wave detector two ends is approximatelyWhen the input due to wave detector does not have There is access circuit or wave detector to come off or when the reason such as cable breakage causes the wave detector incoming end to open a way, it is believed that wave detector it is straight Leakage resistance R1For infinity, now, the magnitude of voltage at wave detector two ends is similar to U=i0×R0.When due to wave detector interface short circuit or During the wave detector access terminal shortcircuit that the reasons such as wave detector itself short circuit are caused, it is believed that the magnitude of voltage at wave detector two ends is similar to 0. Therefore, main control chip 10 can judge the state of wave detector incoming end according to the magnitude of voltage at wave detector two ends.In the present embodiment Only connected by simple circuit, you can accurately judge the state of wave detector incoming end, the efficiency high and intelligence of judgement Change level is higher.

Specifically, as shown in Fig. 2 the node type seismic prospecting instrument in the present embodiment also includes being connected with main control chip 10 Memory module 40.40 USB flash disks of the memory module, the memory module 40 can be with several days of memory node formula seismic prospecting instrument even The data of collection in tens days.Here main control chip 10 has the function of output end with the port that memory module 40 is connected.

Specifically, main control chip 10 is fpga chip.

Below so that above-mentioned node type seismic prospecting instrument includes 3 wave detector voltage collection circuits 20 as an example, to this implementation Disclosed scheme is illustrated:

As shown in figure 3, above-mentioned node type seismic prospecting instrument includes following structure:10,3 wave detectors of master control fpga chip Voltage collection circuit 20, the input of each wave detector voltage collection circuit 20 is connected with external wave detector 51,52,53 respectively. Wherein, the sample range of A/D conversion chips 21 is+2.5V~-2.5V.Three current sources 21 are according to pull down resistor value and wave detector DC internal resistance value and the selection of A/D data conversion chips sample range, take 100uA here;The resistance of pull down resistor is 20K ohm, Drop-down ground connection.

Wave detector status monitoring flow is as shown in Figure 4:Utilize the counter wave detector state of monitoring in every 3 minutes, node After formula seismic prospecting instrument starts, main control chip 10 judges counter, and whether timing was by 3 minutes, if it is not, then counter is from after adding Continue to judge, if by 3 minutes, closed path source switch 23 was waited after certain time, it is determined that enabling A/D after switch closure was turned Change chip 21 and gather 4 data, the stand-by period mentioned here is different according to selected switch difference, when being waited in the present embodiment Between be 10ms.Gather after 4 data, disconnected switch, counter resets again.4 data that each wave detector is collected, point It is secondary to be judged, finally obtain 4 wave detector states, if it is determined that wave detector for a certain state reach 2 times and more than, then finally recognize Determine wave detector and be in the state, and control wave detector status indicator lamp 30 to send out, while status information is write into memory module 40.

Wave detector DC internal resistance in the present embodiment is 1K ohm, in known pull down resistor resistance and current source values, according to FormulaFinally A/D conversion chips collect magnitude of voltage i.e. wave detector two ends electricity under the various states of wave detector Pressure:
