Abstract
The utility model relates to water, electricity, gas composite measuring device and the telemetering system. Which is composed of a computer system (comprises a printer and a carrier communication circuit) and an integrated metering device which comprises a plurality of water meters, gas meters, a pulse generator, a microprocessor, a current transformer, an A/D conversion circuit, a carrier communication circuit, a displaying and alarm circuit and a protection circuit. The rotation of the water meters and gas meters is changed to the signals of electrical pulse. The signals of the electric current and the electric voltage are sent to the microprocessor via the A/D conversion. The microprocessor treats the signals to acquire the corresponding integrated total. The computer collects, summarizes, divides, accumulates and deposits the datum of each metering device through the supply line and the data are printed to put out.
Description
The utility model relates to Computer Applied Technology and electronic-metering technology, is applicable to that city synergic system and resident family use.
Present water,, the measuring apparatus of coal gas all is that machinery or machine-electricity are in conjunction with metering method, according to the document that has retrieved, " a kind ofly has a memory as Chinese patent CN86103822A, the watt-hour meter of telemetry function ", United States Patent (USP) us4573141 and world patent WO8504738, it is separate, adopt the mode of manually sending a duplicate to, workload is very huge, and make mistakes easily, similar device, the utility model adopts computer technology, as gathering and memory component, finishes water with microprocessor simultaneously,, the metering of three parameters of coal gas, and constitute telemetry system by a plurality of this devices and a cover computer system, by the mode of communication data are sent in the computing machine and added up automatically, storage and output result.
The purpose of this utility model is the automatic gauge of realizing electricity, water, three parameters of coal gas, makes full use of the function of computing machine, avoids the repetition of three kinds of parameter metering facilities, obtains bigger social benefit with less investment.
Apply for a patent about the device of watt metering separate case, it is made of the watt-hour meter with automatic protection and telemetry function microprocessor, current transformer, analog-digital converter, carrier communication circuit, holding circuit, demonstration and alarm.The utility model has increased on the basis of this watt-hour meter the metering unit of water, two parameters of coal gas has been constituted.
The purpose of this utility model is achieved in that
At existing water meter, a light emitting diode is installed on the runner both sides of gas meter respectively and a photosensitive tube constitutes pulse producer, its gear teeth make the light path switch-on and-off between above-mentioned two devices when runner rotates, thereby form pulse signal and (also can on a tooth of runner, adorn a block permanent magnet, at its other pulse producer of a coil formation of adorning), whole pulse producer adopts hermetically sealed non-contact structure, with moistureproof and explosion-proof, the signal of two tables is introduced in the microprocessor, Current Transformer detects current signal, sampling resistor provides voltage signal, become digital signal through a/D converter circuit, microprocessor is respectively to this digital signal and water meter, the pulse signal that gas meter is sent here carries out computing, generate three's aggregate-value, deliver on the display and show, display can be the digital lcd plate, it also can be charactron, realize message exchange between measuring apparatus and the remote measurement central computer with carrier communication circuit by AC network, the remote measurement central computer is then by a computing machine, display, disc driver, printer and carrier communication circuit constitute, finish by computing machine that data aggregation gathers and each measuring apparatus is carried out monitoring management, disc driver is realized the permanent storage of data, finishes the output of metering result and each measuring apparatus running status with display and printer.Microprocessor can be reported to the police and protection to abnormal occurrencies such as the overvoltage of power supply, under-voltage, overcurrents; when each power supply, can carry out delay protection automatically; warning device can be a red light emitting diodes or a hummer; the working power of measuring apparatus itself is directly taken out from AC network, and is equipped with a dry cell in order to the continuous working of when outage.
Communication between remote measurement central computer and each measuring apparatus is definition like this.
1. adopt different code lengths, timesharing to use the power supply networking.As: the remote measurement central computer adopts nine word lengths, and each measuring apparatus then adopts 8 word lengths.
2. the remote measurement central computer initiatively sends address code and command parameter, and measuring apparatus is then sent its accumulation results and duty passively.
3. the telemetry system of zones of different adopts different carrier frequencies to carry out communication, thereby guarantees not disturb mutually.
The course of work of the present utility model is:
Little processing when powering at every turn again; automatically delay time; whether test voltage is normal; open holding circuit after normal; implementation is to user's power supply; begin electric current, voltage signal are measured accumulative total; and the order of wait remote measurement central computer; carrier communication circuit detects the address code that the remote measurement central computer is sent here from the power supply networking; whether the automatic identification of microprocessor chooses this device; be then various aggregate-values to be sent to the remote measurement central computer by carrier current channel, serve the status information of this device simultaneously.The remote measurement central computer after sending address code at every turn, promptly wait for various aggregate-values and state that selected table is sent here, accumulate and calculate and the analysis of state, regularly (or according to people's order at any time) exports each user's water, electricity, gas using quantity and the duty that each installs.
The utility model is to use like this:
To directly be concatenated into the power supply networking according to the device that the utility model is made to the circuit between the user, it will be invested an address code.Install the remote measurement central computer in the appropriate location of this electrical network, mounted device is registered, test, verify that this table can be correctly and the central computer communication, and after its measuring accuracy proofreaied and correct, get final product life's work.
Use after the utility model, can realize a plurality of user power utilization amounts in the certain limit, the automatic gauge of water consumption and gas using quantity, the safety to various electrical appliances provides safeguard simultaneously.
