Background technology
Because the raising of modern industry automaticity; Inductive wireless technology has obtained good application in industrial mobile vehicle automation control and management, it has solved two hang-ups of mobile vehicle realization centralized management: the position probing at data communication reliably and mobile vehicle place between central control room and the mobile vehicle.
For the used communication of mobile vehicle position probing, wired mode exists the traction cable inconvenient, or slip ring produces the shortcoming that spark disturbs; Radio communication then exists the error rate high.And induction wireless communication be through be installed in the induction coil in the antenna case on the mobile vehicle and coding cable that the ground rail that is laid in is other in the communications line between 5-20cm closely electromagnetic coupled transmit information, thereby overcome the shortcoming of wire communication and radio communication.In the position probing communication of reality; The used reception antenna of existing position probing adopts the unicoil form more; During installation will with reception antenna and coding cable distance as far as possible near, suppress the interference signal that long-distance transmissions is come with the useful signal that receives by a relatively large margin.Poor anti jamming capability, especially Chinese People's Anti-Japanese Military and Political College's power is with interference performance is poor frequently.Yet along with the development of the modernization of industry, mobile vehicle all adopts RHVC, and the operating frequency of the frequency of generation and induction wireless position detection signal is roughly the same during RHVC work, high-power day apparent the giving prominence to of interference frequently together.Therefore, existing locomotive position detects and can't adapt to requirement with reception antenna.
Summary of the invention
The purpose of the utility model is to improve to the shortcoming and the problem that exist in the background technology, provides a kind of effectively anti-with the special-purpose reception antenna of the induction wireless that disturbs frequently.
Detect the induction wireless reception antenna of locomotive position in a kind of coking automation control; It is characterized in that this antenna be one be installed on the mobile vehicle and with at the other parallel antenna case of coding cable of motorcycle track; Wherein the antenna case is made up of two receiving circuits, and wherein circuit one is formed the frequency-selecting resonant tank by receiving coil L101, capacitor C 101, and coil is made up of two parts; And parallel up and down at a distance of certain distance, be connected with signal amplifier IC101 through resistance R 101, R102; Circuit two is formed the frequency-selecting resonant tank by receiving coil L201, capacitor C 201, is connected with signal amplifier IC201 through resistance R 201, R202.
The utility model is through using checking in industry spot, and the same frequency interference signal of ability good restraining makes the position probing quality obtain effective assurance.
