Positioning device is by building dipper system in house, and as access point, arrangement of base stations exists for the base station of access three or more Distance interval farther out, on the different position of height, the personnel in each region covered into positioning device are both needed to wear signal hair Emitter, personnel, which enter behind the region that positioning device covers, continues emission measurement signal using signal projector, passes through measuring signal The time difference for reaching two access points obtains the current location information of personnel;
The temperature measuring device measures target environment temperature using contact type measurement method, and resistance and temperature is passed On work clothes, target, which needs to put on work clothes just, can measure the environment temperature on its periphery for sensor or thermocouple sensor, One thermal resistance temperature sensor or thermocouple sensor are respectively housed on the front of work clothes, rear portion and two coat-sleeves, when need When detecting the environment temperature on target periphery, 4 sensors on work clothes work at the same time detection environment temperature, the knot that will be obtained Fruit is averaged as environment temperature;
The heating device is infrared lamp or hot-air mouth, and heating device position remains unchanged, and as needed, n is heated Device is arranged at certain altitude, and the heating device of work is needed to execute heating strategy.
Further, whole region being separated into several sub-regions, multiple heating devices are responsible for heating a sub-regions, when When number is more than heating device in subregion, system control sytsem is equal according to obtained heat per capita, the maximum principle of gross energy Calculate the position of heating device;When number is less equal than heating device in subregion, everyone configures one or more heating Device, heating device are moved as the position of personnel is mobile.
A kind of energy-saving heating means positioned using Beidou, include the following steps: that positioning device in real time determines target Position, is sent to coordinated control system for location information;Coordinated control system needs work according to the control of the location information of target One or several heating devices move to designated position;Temperature measuring device real-time measurement target ambient temperature, will be warm Degree information is sent to coordinated control system;Coordinated control system adjusts the operating power of heating device according to Current Temperatures;
Positioning device is by building dipper system in house, and as access point, arrangement of base stations exists for the base station of access three or more Distance interval farther out, on the different position of height, the personnel in each region covered into positioning device are both needed to wear signal hair Emitter, personnel, which enter behind the region that positioning device covers, continues emission measurement signal using signal projector, passes through measuring signal The time difference for reaching two access points obtains the current location information of personnel;
The temperature measuring device measures target environment temperature using contact type measurement method, and resistance and temperature is passed On work clothes, target, which needs to put on work clothes just, can measure the environment temperature on its periphery for sensor or thermocouple sensor, One thermal resistance temperature sensor or thermocouple sensor are respectively housed on the front of work clothes, rear portion and two coat-sleeves, when need When detecting the environment temperature on target periphery, 4 sensors on work clothes work at the same time detection environment temperature, the knot that will be obtained Fruit is averaged as environment temperature;
The heating device is infrared lamp or hot-air mouth, and heating device position remains unchanged, and as needed, n is heated Device is arranged at certain altitude, and the heating device of work is needed to execute heating strategy;
When heating device is infrared lamp, infrared lamp radiant illumination value q and the point to infrared lamp axes that certain point receives Distance r is related with heated current I, the infrared lamp radiant illumination value received at certain point:
Q=f (r, I);
When heating device is hot-air mouth, certain per unit area heater power P for receiving of point and the point to hot-air mouth away from From l, wind velocity v is related with leaving air temp t out, received per unit area heater power at certain point:
P=f (l, v, t);
The effect of coordinated control system is to receive location information and temperature information, formulates the corresponding heating of control strategy control Device gives target heat supply;When one or more targets are in heating region, need to make the radiant illumination value at each target Or per unit area heater power reaches certain value;When having has m target in region, in order to reach heating demand, coordinated control System formulates control strategy, and control strategy is transmitted to the heating device for needing work;Control strategy includes which is controlled to add Thermal work and heating device are heated with great power;

4. the energy-saving heating means according to claim 1 positioned using Beidou, it is characterised in that: connect by measuring signal The mode that the time difference of receipts positions, the time difference reached according to measuring signal, it is the double of focus that personnel, which are located at two access points, On curve, when determining personnel positions, at least need to establish two Hyperbolic Equations, two hyperbolics using third access point The focus of line equation be the personnel's and be coordinate position, authorization amendment is carried out by additional access point, it is more preferable to obtain Positioning accuracy.
