Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
As depicted in figs. 1 and 2, the utility model provides a kind of data acquisition access device, including energy source device 1, storage
Device 2, attachment means 3 and host computer 4.Wherein, attachment means 3 include the data acquisition device 301 being sequentially connected, time control
Device 302, data encoder 303 and data transformation interface 304, for data signal acquisition, processing and output.
Energy source device 1 accesses to attachment means 3, for providing driving power supply for each element of attachment means 3, generally
12V or 24V；Storage device 2 is connected with attachment means 3, for storing the hardware data information obtained for attachment means 3, data
Encoder 303 and data acquisition device 301 are connected with storage device 2, and the data encoder 303 is used to obtain hardware data letter
Normally closed switch amount signal in breath, data acquisition device 301 is used to obtain non-normally closed switch amount signal in hardware data information, to protect
Wiring quantity is demonstrate,proved, storage device 2 can access to data acquisition device 301 by the way of single line COM common points, in the present embodiment
In, data acquisition device 301 refers to from its exterior gathered data and is input to an interface of internal system, is set to be measured
The process of automatic data collection on-off model in standby numeral unit under test；Data acquisition device 301 is internally provided with relay, relay
Device can carry out exclusive Sexual behavior mode to the closure switch amount signal for entering data acquisition device 301, that is, finally enter data acquisition dress
The on-off model for putting 301 disconnects other on-off models closed, to ensure the switching value for entering to time controller 302
Signal remains last on-off model entered；Time controller 302 will be protected once accessing closure switch amount signal
Hold the rear resets of high level signal 0.2S-0.5S or so and export low level signal, until closure switch amount signal is accessed next time；
303 pairs of inputs of data encoder to switching value therein letter is encoded, the data access data transformation interface 304 after coding
(USB interface or RS232 interfaces), and be sent to host computer 4 carry out decoding process obtain incoming switching value information.
In the present embodiment, data encoder 303 uses matrix encoder, and row, column line is respectively switching value
Two end points, line is connected on+5V by pull-up resistor.When entering signal is without closure state, line is in high level state；
When it is closure state to access signal, the line that is connected with this signal and alignment conducting, residing line when signal is closed at
High level, alignment are in low level, and the state position of switch is uniquely determined by line number and row number, and line number and row number are entered respectively
Row binary coding.
As shown in figure 3, by taking cart direct of travel in master controller of driving a vehicle and the access of driving switch amount signal acquisition as an example
To illustrate the operation principle of the present apparatus：
Cart left lateral, right lateral signal are normally closed combination switch amount signal, and the left lateral, the normally closed combination switch amount signal of right lateral is direct
Access to data encoder 303 to be encoded, cart traveling gear is 1-4 gear, i.e. left lateral, right lateral there are 4 speed respectively
Gear, driving 1-4 driving switch amount signals access to data acquisition device 301；
After 1 gear switch amount signal accesses the relay J1 in data acquisition device 301, other gears (2 grades, 3 grades, 4
Shelves) in any one on-off model access data acquisition device 301 in on-off model, it will be cut by respective relay
The working condition of relay J1 where disconnected 1 gear switch amount signal, the relay where the driving switch amount signal accessed afterwards is opened
Beginning work, here it is the exclusive Sexual behavior mode of data acquisition device 301；Similarly, when 2 gear switch amount signals access data acquisition device
After relay J2 in 301, any one on-off model accesses data acquisition in other gear (3 grades, 4 grades) on-off models
In device 301, the working condition of the relay J2 where respective relay 2 gear switch amount signals of cut-out will be passed through；Similarly, 3
Shelves, 4 grades of on-off model also pass through such exclusive Sexual behavior mode, the output of data acquisition device 301 is only kept last
The state of the driving switch amount signal of individual access；
Via the on-off model turn-on time controller 302 of data acquisition device 301, the characteristic of time controller 302 is
Access signal is changed into the high level moment by low level, keeps high level signal 0.2S-0.5S (adjustable according to actual conditions)
Transformation is output as low level signal afterwards, and the on-off model handled well is transmitted to data encoder 303, by data encoding
Device 303 is converted into the general usb protocol or RS232 signals of standard by data transformation interface 304 after encoding, and is uploaded to
Position machine 304, host computer 304 decoded by corresponding standard agreement, obtains opening for real-time direction of traffic and speed stage
Measure information in pass.
Obviously, above-described embodiment of the present utility model is used for the purpose of clearly illustrating the utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.There is no need and unable to give all embodiments
