Background technology
Family on existing domestic, the international market all is battery-powered with the heat energy table, and heat management enterprise is the heat energy table that is connected to the user through the transmission data wire to the user data collector, gathers the heat energy table user heat energy use amount of every day; Described heat energy table utilizes battery to give the power supply of metering electronic circuit; But battery is shorter useful life, the battery electric quantity deficiency often occurs, causes the continuous data of heat energy table inaccurate; This makes popularization heat energy table receive obstruction to the shortcoming of life.
Summary of the invention
The object of the present invention is to provide a kind of heat energy table teletransmission electric supply installation; Solve heat energy table battery short defective in useful life with teletransmission data transmission system technology; The present invention does not influence data communication, does not increase the heat energy hypergene and produces operation, increases the cost of producing the heat energy table hardly.
The present invention realizes through following technical scheme: a kind of heat energy table teletransmission electric supply installation comprises data acquisition unit, data line, data isolation circuit, polarity automatic identification circuit, constant-current source circuit and battery.Described data acquisition unit is provided in a side of heat management enterprise; Described data line is the stube cable between data acquisition unit and user's the heat energy table, and described data isolation circuit, polarity automatic identification circuit, constant-current source circuit increase in former heat energy watch circuit.
The technical scheme of replenishing battery electric quantity with the teletransmission power supply is: when data acquisition unit energising work; M-Bus downstream end in the data acquisition unit can produce the output voltage of a 10～50V; It is characterized in that described output voltage enters into the M-Bus input of heat energy table through data line; Electric current after the data isolation circuit is isolated data-signal, isolate gets into the polarity automatic identification circuit, produces a source current that meets heat energy table power supply polar requirement, gets into the electric current that constant-current source circuit produces microampere order; Replenish electric weight to battery; Battery is as pressurizer, to the entire circuit power supply of heat energy table, thereby reached additional battery electric quantity, prolong the battery purpose in useful life.
The present invention has the innovation of structure aspects, it is characterized in that: the constant-current source circuit that in the primary electron circuit of heat energy table, increases data isolation circuit, polarity automatic identification circuit and microampere order.
Those skilled in the art's simple change and replacement all are within the protection range of characteristic of the present invention in this area.
The invention has the beneficial effects as follows: utilize the remote transmission data system technology that the heat energy table is carried out the realization that teletransmission is supplied power, the beneficial effect of following three aspects is arranged:
1, on the basis that does not influence data communication, solved battery short defective in useful life in the heat energy table.
2, at the electronic component that only increases minute quantity (concerning whole telogenesis this; Can omit and disregard), do not increase the heat energy hypergene and produce under operation (originally production process the is constant) situation, use heat energy table of the present invention in competition; Can obtain tangible client's advantage, be exactly looked at by user's parent.
3,, promote the heat energy table, but battery is short useful life in the heat energy table for energy-conservation; Influenced the popularization of heat energy table; The present invention can prolong the useful life of battery, has cleared away technology barrier for the work of popularization heat energy table, just promotes for energy-conserving product and has made critical contribution.
