Abstract
An equipment state monitoring mobile terminal device capable of realizing remote high-speed data transmission through a wireless communication network adopts an embedded computer system structure. A constant-current power source, a vibration and temperature sensor is connected to the terminal device, a microprocessor is communicated with a data acquisition module through a SPI (Serial Peripheral Interface) bus and transmits acquired data to a 3G (3rd Generation mobile communication technology) wireless communication module through a USB (Universal Serial Bus). Monitored data transmission speed is greatly increased as the 3G wireless communication technology is adopted to transmit the data. In addition, the equipment state monitoring mobile terminal device is particularly suitable for remotely monitoring states of large-sized equipment in mobile operation.
Description
Affiliated technical field
The utility model relates to a kind of equipment condition monitoring mobile terminal apparatus, especially can carry out the mobile terminal apparatus of real-time online status monitoring by 3G (3rd Generation 3G (Third Generation) Moblie technology) cordless communication network high speed transmission data in monitored equipment moves.
Background technology
The large-scale visual plant of some operations in moving, as truck, excavator, loading machine etc., its operation conditions direct relation safety and production and economic benefit are carried out on-line real time monitoring to equipment state, the fault and the hidden danger of discovering device that can be promptly and accurately.The major parameter of equipment condition monitoring is the vibration and the temperature of monitored target key position, and wherein vibration signal generally needs more than image data 320k bit each second.These data need be transferred to monitoring station and carry out analyzing and processing by professional and technical personnel and special computer software, come judgment device state and analytical equipment fault.Therefore need and to gather vibration and temperature signal in real time, and carry out the mobile terminal apparatus of high speed data transfer by radio communication.
Existing same device uses CDMA (Code Division Multiple Access code division multiple access) 1X (spreading rate 1) or GPRS wireless communication technologys such as (General Packet Radio Service GPRSs) the transmission data of 2.5G (2.5 third-generation mobile communication technology).2.5G in fact the speed of wireless communication technology transmission data can only reach 20k～30k bit, can not satisfy the real-time requirement of mobile operating equipment state on-line monitoring far away.
Summary of the invention
In order to overcome the problem that existing mobile operating equipment condition monitoring terminal installation can not high speed transmission data, the utility model provides a kind of mobile terminal apparatus of the 3G of the employing communication technology.Be provided with constant-current supply in the device, be used to the built-in circuit piezoelectric transducer and the thermal resistance sensor that are connected that excitation is provided; Under microprocessor control, gather vibration and temperature signal, the data of gathering are sent to the remote computer of monitoring station by the 3G cordless communication network.Have the advantages that volume is little, low in energy consumption, transmission rate is high, the remote live on-line condition monitoring of the main equipment of operation in being particularly suitable for moving.
The technical scheme that its technical problem that solves the utility model adopts is: adopt the embedded computer system structure, on printed circuit board (PCB), the constant-current supply module links to each other with modulus conversion chip, modulus conversion chip, wireless communication module and memory chip link to each other with microprocessor respectively, and the 3G wireless communication module links to each other by usb bus with microprocessor.Model provides excitation for the constant-current supply module generation milliampere level electric current of TL317 for transducer; Model is that the modulus conversion chip of AD7490 is under the microprocessor control of S3C2440A in model, tested vibration, temperature signal are converted to digital signal, give microprocessor by SPI (Serial Peripheral Interface serial peripheral interface) bus transfer; Model is that the 3G wireless communication module of SIM5210 carries out transfer of data by WCDMA (wideband CDMA) network under the control of microprocessor.The program of mobile terminal apparatus and storage are in the memory of system, and memory comprises that model is that the flash memories of AM29LV160DB, flash memories and the model that model is K9F1208 are the random asccess memory of HY57V561620.
The beneficial effects of the utility model are that use 3G wireless communication module sends data, can provide the upstream rate of 384K, so monitor equipment status and the needed mass data of diagnostic device fault can be transferred to monitoring station in mobile high speed.
