A measurement sensor, a pressure sensor and a data acquisition and transmission module are added on an ordinary mechanical water meter, and all functional modules and the mechanical water meter are combined into a whole. The utility model adopts a disposable lithium battery as an operational power.
Description
Affiliated technical field
The present invention relates to a kind of device, the especially measured value that can measure water supply pipe pressure and variable simultaneously transmits out by the mode of wireless GSM/GPRS/CDMA.
Background technology
At present, in the tap water supply management, water supply pipe pressure is to take from the manometric force value on the waterpipe or rent special-purpose commercial wireless channel the manual read pressure value that collects is sent to water supply administrative authority, pools together the pressure condition of observing whole water supply network then; The metering of tap water is that water meter or flowmeter are installed on water supply line, and by the mode water-meter reading of artificial or electronics or the variable of flowmeter, the variable of electronics water-meter reading often passes through the common frequency channel transmission mode of wire transmission mode or broadcasting.The metering of pressure of supply water and water supply is the two item number certificates that water supply department must be monitored, every independent collection certainly will be made troubles, simultaneously, adopt the mode of wired or wireless radio network to transmit data, system need consume bigger power, then need the support of external power source, be subjected to the restriction of infield and transmission range easily.
Summary of the invention
Can't realize the deficiency of long-distance transmissions for the data of the instrument that solves pressure and the no synchronous acquisition of metering in the existing tap water supply link and collection, patent of the present invention provides a kind of tester, this tester is gathered water supply pipe pressure and continuous data unification, and will gather to such an extent that data are passed through the GSM/GPRS/CDMA channel transfer of mobile phone to the department that needs to monitor pressure of supply water and metering.The signal transmission passage coverage rate scope that this water supply radio pressure, metrology and measurement instrument adopt is wide, guarantees collection point transmission signals non-blind area, very-long-range transmission; Pressure, metering to water supply line realize unmanned remote measurement.
The technical scheme that the technical matters that patent of the present invention solves adopts is: on common mechanical water meter, be installed in the compartment of a sealing, placement force and metering collecting circuit board in the compartment, the signal sending circuit plate, pressure transducer is contained on the housing of water meter, the water meter measurement sensor is installed on the water meter gear, the pressure sensor signal line, metering pick-up transducers signal wire inserts pressure and the metering collecting circuit board in the compartment, integrated central signal processing unit (CPU) on pressure and the metering collecting circuit board, the A/D change-over circuit, the switching value signal acquisition circuit, clock circuit, data storage circuitry and electric power management circuit; Signal sending circuit adopts general GSM/GPRS/CDMA module.Pressure and the switching value signal acquisition circuit of metering on the collecting circuit board deposit in the switching value signal of the water meter measurement sensor that collects in the digital memory circuit after treatment, clock circuit produces periodic clock signal and gives CPU, CPU reads clock signal, if the time of setting, CPU changes the force value that reads pressure transducer by A/D, and force value that collects and the water meter measurement value that is stored in data storage circuitry are sent from signal sending circuit.CPU is by the control electric power management circuit, the power consumption of each several part circuit is dropped to minimum, but the purpose of each several part circuit long-term stable operation when guaranteeing powered battery.It is rod dress or sucked type vast of heaven line that signal sends the antenna that adopts.
Patent obvious effects of the present invention is, can far distance automatic measurement water supply pipe pressure of supply water and the variable of tap water, and do not need the additional power supply support to get final product long-term work, simultaneously, the present invention adopts the integrated water-proof design, is convenient to install in a humid environment.
