Abstract
The utility model discloses a radio force transducer with low power consumption. Pressure signals are converted into radio-frequency (RF) signals for transmitting. Wiring is not needed, and the transducer can be arranged at any position. A power supply management circuit is adopted, so the radio force transducer with low power consumption is in a low power consumption state (only dozens of microamperes) when a crane does not work.
Description
1, affiliated technical field
The utility model relates to a kind of force-measuring sensing apparatus, and especially the sensor signal transmission mode is the wireless RF radiofrequency signal, and low in energy consumption, uses alkaline battery can use 1-2.
2, background technology
At present, the principle of the force cell that uses on the crane commonly used is to use answers electric sheet, is sinusoidal electric signals with pressure (or pulling force) signal transition; Re-use transmitter, change sinusoidal electric signals into linear voltage signal (or current signal).The voltage signal of sensor need be transferred to the limiter of moment of pilothouse with communication cable (about 150 meters), thereby realizes measurement and monitoring to pressure.
In actual applications, because cable length is very long, signal attenuation, wiring complexity can occurs, problems such as overhauling difficulty is installed, this communication modes brings very big puzzlement for the collection of pressure signal.
3, summary of the invention
For fundamentally solve signal attenuation, wiring that the cable transmission signal brings complicated, problem such as maintenance difficulty is installed, the utility model adopts the mode transmission sensor signal of wireless RF radio-frequency communication, and power supply carried out power management, power consumption is reduced, need not wiring, sensor can be installed in the optional position.
The technical scheme that its technical matters that solves the utility model adopts is: change pressure signal into the wireless RF radiofrequency signal and transmit; Use electric power management circuit that power supply is managed, make this low-consumption wireless force cell when crane is not worked, be in low power consumpting state; Use heartbeat to wake up simultaneously and vibroswitch wakes two kinds of methods up and wakes work up.Increase by one at the force cell back of using at present and change voltage signal the device of wireless RF radiofrequency signal into, this device is made up of control circuit board, supplying cell two parts.Supplying cell is 2, and a battery is the 3.6V lithium rechargeable batteries, is the control circuit board power supply; Another piece battery is the 9V alkaline battery, is the sensor power supply, and charges for the 3.6V lithium rechargeable batteries.
Control circuit board is made up of AD voltage collection circuit, wireless RF radiofrequency signal reception radiating circuit, electric power management circuit three parts.Is digital signal by the AD voltage collection circuit with the voltage signal acquisition of force cell; Carry out communication by wireless RF radio frequency reception radiating circuit and limiter of moment again, give limiter of moment digital data transmission.
Electric power management circuit manages power supply, and when crane was not worked, control circuit board was in dormant state, 3.6V the lithium rechargeable batteries power consumption has only several microamperes, the 9V alkaline battery is not the force cell power supply, only is the charging of 3.6V lithium rechargeable batteries, and power consumption also has only several microamperes; When crane is worked (heartbeat wakes up and vibroswitch wakes two kinds of methods and usefulness up), control circuit board is in running order, and the 9V alkaline battery is the force cell power supply, tens milliamperes of power consumptions, but power-on time is very short, so power consumption is very low.Battery can use 1-2 at least, when battery electric quantity is not enough, also only needs to change the 9V alkaline battery and gets final product.
The beneficial effects of the utility model are, the signal of force cell can not decayed, and need not wiring, and sensor can be installed in the optional position.Make things convenient for crane to install and use force cell, pressure is measured and monitored.
4, description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is integral installation figure front.
Fig. 2 is integral installation figure side.
Fig. 3 is the circuit theory diagrams of control circuit board.
Among the figure: 1, low-consumption wireless force cell, 2, voltage signal changes wireless RF radiofrequency signal device into, 3, control circuit board, 4, control circuit board-AD sampling section, 5, control circuit board-wireless RF radio frequency receives radiating portion, and 6, control circuit board-power management part, 7,9V alkaline battery, 8,3.6V lithium rechargeable batteries, 9, communication antenna, 10, wire rope.
5, embodiment
As shown in Figure 1: voltage signal changes the back that wireless RF radiofrequency signal device (2) is placed on low-consumption wireless force cell (1) into, is screwed; Voltage signal changes wireless RF radiofrequency signal device (2) into and comprises three parts, control circuit board (3), 9V alkaline battery (7), 3.6V lithium rechargeable batteries (8); Control circuit board (3) comprises three parts, and AD sampling section (4), wireless RF radio frequency receive radiating portion (5), power management part (6).
Low-consumption wireless force cell (1) is connected with control circuit board-AD sampling section (4), carries out voltage signal acquisition; 9V alkaline battery (7), 3.6V lithium rechargeable batteries (8) are connected with control circuit board-power management part (6), by control circuit board power supply are managed, and power consumption is reduced; Communication antenna (9) receives radiating portion (5) with control circuit board-wireless RF radio frequency and is connected, and emission, reception RF radiofrequency signal are carried out communication with limiter of moment.
As shown in Figure 2, low-consumption wireless force cell (1) is connected with wire rope (10).
In the practical application, when crane is not worked, control circuit board (3) is in dormant state, control circuit board-power management part (6) control 9V alkaline battery (7) is not low-consumption wireless force cell (1) power supply, 3.6V lithium rechargeable batteries (8) also is in low power consumpting state, only tens microamperes of whole low-consumption wireless force cell power consumption.
Use heartbeat to wake up simultaneously and vibroswitch wakes two kinds of methods up and wakes work up, guarantee that when crane was worked, control circuit board (3) was in running order.Control circuit board-power management part (6) control 9V alkaline battery (7) is low-consumption wireless force cell (1) power supply.Wire rope (10) produces pressure to low-consumption wireless force cell (1), thereby generation voltage signal, voltage signal is transferred to control circuit board-AD sampling section (4) and is transformed into digital signal, receive radiating portion (5) by control circuit board-wireless RF radio frequency again and utilize communication antenna (9) to be transmitted to limiter of moment digital signal, thereby realize pressure is measured and monitored.
