A kind of wireless kilowatt meter reading-out system that wakes mode based on magnetic up
(1), technical field
The utility model relates to a kind of wireless kilowatt meter reading-out system, particularly relates to a kind of wireless kilowatt meter reading-out system that wakes mode based on magnetic up.
(2), background technology
Along with social progress and economic development, the manual metering of gauging table (water, electricity, gas and heat energy) can't satisfy the new demand that gauging table is checked meter, and there is very big defective in manual metering:
(1), cost height: manual metering from house to house is undoubtedly a big expense of water supply, power supply, air feed and heat supply company.
(2), accuracy is low: the manual metering poor accuracy, this can cause supplying water, the profit of power supply, air feed and heat supply company runs off, it also is a great problem of improving service quality that mistake is chargeed.
(3), can't finish on time and check meter: when gauging table is installed in the user when indoor, manual metering can't carry out when the no one was in, and caused the task of checking meter to finish on time.
(4), can't realize checking meter in real time: this requirement is checked meter and can be finished at short notice to satisfy water supply, power supply, air feed and the heat supply company demand to real-time used data.
(5), can't realize time-shared charge: time-shared charge in power supply, is the efficient ways that solves imbalance between power supply and demand and power shortages especially.Mensal manual metering can't solve this difficult problem at all.
(6), can not carry out remote monitoring: real-time monitoring is the effective method that prevents the tax evasion phenomenon, and manual metering is difficult to finish.
(7), service quality is not high: for the user provides more detailed continuous data is the key of improving service quality, and this also helps to improve society to resources effective and reasonable use, and manual metering can't be accomplished detailed data metering.

The telephone reading meter data technology: this technology is to use telephone wire as media continuous data to be uploaded.Its requires at the user side modulator-demodular unit of having a telephone installed, and links to each other with gauging table.In the meter reading central terminal server, need hold a large amount of modulator-demodular units in order to collect meter data.This technology is system cost height, installation complexity not only, and a large amount of trunk call lines need be applied in the meter reading center.When checking meter, need take user's telephone wire.This mode is the cost of use height not only, also makes troubles to the user simultaneously.To there not being the user of phone, this mode can't realize.Though this technology still is used, has been limited in very little scope, and has been eliminated gradually.
The low voltage power line carrier technology: this technology is to use line of electric force as media continuous data to be uploaded to the regional centralized station by gauging table, utilizes other media with information uploading again.This technology is simple, but has a lot of problems, and, speed low as reliability is slow, it is complicated to install, be subjected to the applied environment restriction, only be applicable to ammeter, power consumption is big, cost is high.
IP electric energy meter technology: this technology receives the concern of some enterprises at home, but a key issue that so far can't technical solution, that is exactly how continuous data to be delivered to the internet to get on.Reality is, the internet does not reach every family, even the family of internet is arranged, also the effective way of neither one allows continuous data " online " so far.This technology is believed and can only be confined on the data protocol, and can't become the main product of industry.
The radio meter register technology: the radio meter register technology is to utilize the radio signal of some frequency that continuous data is uploaded, have reliability height, speed fast, realize that multilist is read altogether, low power consumption and other advantages.But too high, the complex structure of the cost of finishing this technology has hindered its development, promotion and application.
(3), summary of the invention
The purpose of this utility model is to overcome problems of the prior art, provides a kind of cost low, simple in structure, time saving and energy saving a kind of wireless kilowatt meter reading-out system that wakes mode based on magnetic up.Be implemented in 200~300 meters distances and can realize point-to-point radio meter register function.
The utility model comprises: gauging table, palm kilowatt meter recorder, computer data information board, zone controller, described zone controller is provided with microprocessor, internal memory, export-oriented interface module, information logging modle, be provided with the wireless meter reading module of micropower in the information logging modle, described micropower is wireless, and meter reading module one end is provided with antenna, and the other end is connected with gauging table.
Described palm kilowatt meter recorder comprises hand-held set and magnetic wake-up master module, magnetic wake-up master module one end is provided with antenna, the other end is connected with hand-held set, and the palm kilowatt meter recorder is connected with the computer data information board by the USB mode, carries out data information transmission.
Meter reading module that described micropower is wireless comprises that the base table control chip wakes the table module up with the magnetic that links to each other with the base table control chip, and described magnetic wakes the table module up and links to each other with antenna.
Be respectively equipped with connection gauging table and the interface that is connected power circuit on the described base table control chip, the base table control chip is provided with clock circuit.
