Abstract
The utility model discloses an M-bus host of a collector, which comprises a CPU (Central Processing Unit), a transmission circuit, a receiving circuit and an M-bus, wherein the CPU transmits information to an intelligent meter by the transmission circuit and the M-bus, and receives information of the intelligent meter by the M-bus and the receiving circuit. The M-bus host of the collector is characterized in that the transmission circuit consists of a power supply, an optical coupler, a voltage stabilizing tube, a three-end voltage stabilizing block and a protector, the optical coupler is connected with the voltage stabilizing tube, and the on and off of the voltage stabilizing tube can be controlled by the on and off of the optical coupler, so that the voltage difference stabilized by the voltage stabilizing tube can be generated for the base electrode of the three-end voltage stabilizing block, so that the three-end voltage stabilizing block outputs a voltage difference with a voltage stabilizing property of the voltage stabilizing tube so as to meet the MBUS sending requirement. The M-bus host of the collector has the advantages of simple, stable and reliable circuits, adoption of common devices, relatively low cost, extreme easiness of production and the like.
Description
Technical field
The utility model relates to a kind of collector M-bus main frame.
Background technology
Collector is to be used to gather a plurality of electric energy meters or intellectual water meter or gas meter, flow meter information, and can with the equipment of concentrator swap data.
M-bus communication host module, its order wire removes can exchanges data can also provide electric current, voltage to use to slave unit, and this Circuits System has solved the difficult problem of slave unit power taking.Circuit comprises power supply power supply unit, CPU control module, sends data cell, receiving data units.The main frame transtation mission circuit utilizes level to change transmission information and gives slave unit, and main frame receives the 20mA electric current loop of slave unit transmission, and main frame needs to transfer the signal of this electric current loop to the TTL digital quantity by analog quantity.Existing its transtation mission circuit of M-bus communication host module generally is to utilize the core of integrated circuit as transtation mission circuit, relies on power amplifier outwards to send data.Such as the ANALOG-BOARD Revision5.1 in the Meter Bus Application scheme of American TI Company, what Lleida scheme etc. all adopted is this transtation mission circuit.The deficiency of this transtation mission circuit is that circuit design is complicated, product price is expensive, volume is big.
Therefore how simplified design reduces aspect such as product price and deals with problems, and satisfies the demand of collector M-BUS main frame.
The utility model content
The purpose of the utility model is to provide a kind of transtation mission circuit simple and stable reliable, the collector M-bus main frame that cost of products is low.
This collector M-bus main frame that the utility model provides; Comprise CPU, transtation mission circuit, receiving circuit and M-bus bus; CPU delivers to information intelligence table meter and receives the information of intelligence table meter through M-bus bus and receiving circuit through transtation mission circuit and M-bus bus, it is characterized in that said transtation mission circuit by power supply, optocoupler, stabilivolt, three-terminal regulator block and protect device to form, and optocoupler is connected with stabilivolt; Whether the break-make of the break-make control stabilivolt through optocoupler; The pressure reduction that produces the voltage stabilizing of stabilivolt institute is given the base stage of three-terminal regulator block, makes the voltage difference of three-terminal regulator block output stabilivolt stabilizing voltage characteristic, satisfies MBUS and sends requirement.
Said power supply is one road 36V single supply.
The utility model circuit is simple, and the device of employing is common, and power supply gets final product work by one road 36V single supply, and relative cost is low, and circuit is simple and reliable.
