Abstract
The utility model relates to an intelligent reprogrammable remote measuring terminal capable of being used for integrating acquisition, storage and transmission of data of water situations of the water conservancy, comprising a multi-mode self-adaptive power supply unit, a hardware acquisition circuit unit, a storage receiving and sending unit and a central processor; and the whole circuit is packaged in an aluminium shell which has good ground connection performance. By a circumscribed flow monitoring appliance (such as an electromagnetic flow meter) and a communication appliance (such as a GPRS and a CDMA), the intelligent reprogrammable remote terminal system realizes the functions of the acquisition and transceiving of the corresponding information of water situations, the acquisition of the remote control information, the remote upgrade of a software system and the like.
Description
Affiliated technical field
But the utility model relates to a kind of telemetry terminal system that can be used for the water conservancy hydrologic data collection, stores, is transmitted in the intelligence overprogram of one, it is made up of multi-mode self-adaptive power supply unit, hardware Acquisition Circuit unit, storage Transmit-Receive Unit and central processing unit, and entire circuit is packaged in the aluminium casing with good earth performance.By external flow monitoring utensil (as: electromagnetic flowmeter), communication apparatus (as: GPRS, CDMA) is realized functions such as obtaining of the collection of corresponding regimen information and transmitting-receiving, Long-distance Control information.
Background technology
The equipment that in the past was applied to aspects such as water conservancy regimen is based on metering instrument mostly, this kind equipment can only play the function of digital display, must adopt manual type to carry out the scene to obtaining of hydrologic regime data makes a copy of, the manual control device carries out the control of discharge, and this kind pattern had not only fallen behind but also labor intensive, material resources and financial resources.The current domestic long-range transmitting-receiving that also has this type of device of part to adopt Single Chip Microcomputer (SCM) system realization data message, however function is comparatively single, and poor expandability can't be carried out the reparation and the renewal of software systems.
Summary of the invention
In order to realize that hydrologic regime data observes and predicts the intelligent and increasingly automated of work, the invention provides a kind of intelligence regimen telemetry terminal system able to programme, this equipment is by external flow monitoring utensil (as: electromagnetic flowmeter, water level gauge), obtaining of the collection of the corresponding regimen information of communication apparatus (as: GPRS, CDMA) realization and transmitting-receiving, Long-distance Control information, power alarm, the realization regimen is observed and predicted the unmanned at station.In addition, this device software system has and can repair and update functions.
The technical solution adopted in the utility model is: circuit adopts modular design, and the entire circuit of telemetry terminal system is divided into power supply unit, collecting unit, storage unit, communication unit and central processing unit.All adopt interface to be connected between module and the module.Power supply unit adopts soft switch designs, by the central processing unit procedure identification, can insert DC12V, 24V direct current and AC 220V alternating current.Collecting unit has added special digital filter circuit, can handle carry out digital filtering from external appliance monitor signal.Communication unit has designed 232,485, the usb communication interface, supports wireless station, dialing, multiple communication modes such as GPRS, GSM.Central processing unit adopts the Flash chip, and its internal program can carry out remote upgrade and renewal by communication.
The beneficial effects of the utility model are:
1, through modular design, the independent dismounting of trouble unit can be repaired or replaced, improved the flexibility ratio of plant maintenance;
2, the power supply unit part can insert the voltage of plurality of specifications, has guaranteed that equipment also can use at non-Electric region.；
3, communication interface is abundant, can realize the access of the communication apparatus of distinct interface;
4, can carry out scene or remote upgrade and renewal by computing machine.
Description of drawings
Accompanying drawing is an organigram of the present invention.
1 is the multi-mode self-adaptive power supply unit among the figure; The 2nd, hardware Acquisition Circuit unit; The 3rd, the storage Transmit-Receive Unit; The 4th, central processor MCU.
Embodiment
The multi-mode self-adaptive power supply unit provides 2 power supply input ports, and one of them exchanges input as AC220, and another selects suitable power supply input port as the input of direct current 12V/24V direct supply according to on-the-spot actual electric power thus supplied.Designed 485,232 in the hardware Acquisition Circuit unit, the usb data interface, connect with the active or passive sensor that satisfies distinct interface.Acquired signal reaches central processing unit by analog to digital conversion circuit and digital filter circuit, stores E after treatment into
2In the array.E in the storage Transmit-Receive Unit
2Array increases and decreases as required, and data message can connect the communication apparatus teletransmission to the data service center by telecommunication circuit.Central processor MCU is as the core devices of equipment, the control bit of portion's configuration software upgrading within it, and by visiting this control bit, the device software system can carry out remote upgrade and renewal.
