Description
Technical field:
The utility model belongs to measuring apparatus manufacturing technology field, is a kind of exploration instrument.
Background technology:
Need the distance between accurate position, humiture and the adjacent office station to the place to measure in the design process of communications office site before building, because generally all there is barrier in office between the station, can't record air line distance, also to find a measurement point, measure the distance that the measurement point branch is clipped to two adjacent office stations, measure the angle between these two lines again,, also will measure the voltage drop of cable between the adjacent office station after communications office site's construction is finished by calculating the distance between the adjacent office station.Current measuring methods is to adopt independent surveying instrument that above-mentioned numerical value is measured respectively, calculates complicated operation, inefficiency again by computing machine.
Summary of the invention:
The technical problems to be solved in the utility model is to disclose the complete portable multi-function exploration instrument of a kind of measurement function.
The scheme of the utility model technical solution problem is to adopt the GPS steady arm, the temperature and humidity measurement instrument, pressure measuring instrument, stadimeter, angular instrument, central processing unit, display and keyboard constitute portable multi-function exploration instrument, wherein the GPS steady arm adopts the SDT11 module, the temperature and humidity measurement instrument adopts the DHT95 module, pressure measuring instrument adopts the ICL7135 chip, stadimeter adopts the BJFT-FTM-200 chip, angular instrument adopts the RSC2800 module, central processing unit adopts ARM920T, the GPS steady arm connects the DP0 pin and the DN0 pin of central processing unit respectively by two groups of USB control lines, the clock line of temperature and humidity measurement instrument connects the IICSCL pin of central processing unit, the data line of temperature and humidity measurement instrument connects the IICSDA pin of central processing unit, the output line of pressure measuring instrument connects the TCLK1 pin of central processing unit, the output line of stadimeter connects the TXD0 pin of central processing unit, the feedback line of stadimeter connects the RXD0 pin of central processing unit, the output line of angular instrument connects the ADDR0 pin of central processing unit, and central processing unit is connected with keyboard with display respectively.
Stadimeter and angular instrument are formed the fixed point stadimeter, and one is BJFT-FTM-200 type laser range sensor, and another is a RSC2800 type angular transducer, and two class sensors are adjusted the distance respectively and angle is measured.BJFT-FTM-200 type technical grade laser range sensor is the sensor that has the RS232 data-interface, makes things convenient for data acquisition.Range reaches 200 meters, and distance accuracy is better than 1 millimeter.The data of this sensor output can be sent into MCU by serial RS232 mouth and carry out data processing and result's demonstration.RSC2800 is an angular transducer, this sensor can convert the anglec of rotation to corresponding analog voltage signal, because integrated ADC change-over circuit in the ARM chip itself, so this sensor output can be connected directly to the AD input end, send into CPU and pass through the software algorithm data processing through the AD conversion, can obtain the distance measure in 2 in space with the output of range sensor.
What temperature and humidity measurement adopted is the SHT11 sensor, and this sensor can be measured relative temperature and humidity simultaneously, and one 14 AD converter Direct Digital output is contained in inside.Export because sensor be a numeral, employing be serial i
2So C interface is can be directly and the I of ARM
2C interface is connected, the IICSDA pin of ARM when the data line of SHT11 connects, and the clock line of SHT11 is connected to the IICSCL pin of ARM.The humiture data of collection in worksite send into directly by this interface that MCU handles and reality.
The ICL7135 chip of main flow is adopted in voltage measurement, and this chip is special-purpose voltage measurement chip, and input impedance is big.Because voltage measurement divides direct current and exchanges two kinds, so can carry out the stepping setting to it.Direct current signal is sent to the ICL7135 input end through the precision resistance dividing potential drop and carries out the AD conversion.Magnitude of voltage after collection input ARM kernel, and, calculate the Capacitance Unbalance in Telecom Cables footpath according to the distance between 2 that gather early stage.
What GPS adopted is the SDT11 module of atmel corp, and this module has the induction of superelevation, up to-158dBm, support battery saving mode, the standby current of 5uA, and support the numeral of USB and two kinds of forms of UART to export.Because the ARM chip has usb interface controller, and the number of leads of USB interface is few, speed is fast, so adopt the USB interface of this module to be connected with ARM.The ARM chip has 2 groups of USB control pins, adopts first group of DP0, DN0 to be connected with it here.The GPS address information is passed to MCU and carries out software processes by this interface, finally shows on LCD.
The utility model can satisfy needed technical parameter in communications office site's design process, and generates needed value automatically, and the degree of accuracy height is easy to operate, high efficiency.
