Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The embodiment of the application provides an incoming call self-starting control device of a real wind profile radar, which can realize the incoming call self-starting of the wind profile radar under the conditions of frequent power failure and unstable voltage of a mains supply so as to improve the environment adaptability of the wind profile radar.
Referring to fig. 1, the incoming call self-starting control device of the wind profile radar mainly includes: the system comprises an analog-digital conversion processing circuit 101, a first solid-state alternating current relay 102, a second solid-state alternating current relay 103, at least one path of alternating current sampling and shaping circuit 104 and first switch circuits 105 with the same number as the alternating current sampling and shaping circuit 104.
Wherein: the analog-to-digital conversion processing circuit 101, the alternating current sampling and shaping circuit 104 and the first switch circuit 105 are all arranged on the circuit board, a sampling end of the alternating current sampling and shaping circuit 104 receives an alternating current sampling signal corresponding to an alternating current sampling point, and the alternating current sampling signal represents a voltage sampling signal of a mains supply received by the incoming self-starting control device; the output end of the ac sampling and shaping circuit 104 is connected to the first input end of the analog-to-digital conversion processing circuit 101, and outputs an ac sampling and shaping signal.
A first output terminal of the analog-to-digital conversion processing circuit 101 is connected to an input terminal of the first switch circuit 105, and outputs a switch control signal. Specifically, the switch control signal is a signal for controlling the on/off of the first switch circuit 105.
The output end of the first switch circuit 105 is connected with the control end of the first solid-state alternating current relay 102 and the control end of the second solid-state alternating current relay 103 respectively to output a relay control signal, the first solid-state alternating current relay 102 is connected in series between the uninterruptible power supply output end of the wind profile radar and the commercial power access end of the transmitting cabinet through the input and output end of the first solid-state alternating current relay 102, and the second solid-state alternating current relay 103 is connected in series between the uninterruptible power supply output end and the commercial power access end of the receiving cabinet through the input and output end of the second solid-.
In practical application, if the number of the ac shaping circuit 104 is set to 1, the ac shaping circuit 104 outputs one ac sampling shaping signal to the analog-to-digital conversion processing circuit 101, and the corresponding analog-to-digital conversion processing circuit 101 performs analog-to-digital conversion on the ac sampling shaping signal and outputs one switch control signal; similarly, if the number of the ac shaping circuit 104 is 2, the analog-to-digital conversion processing circuit 101 outputs two switch control signals, that is, the number of the ac sampling shaping circuit 104 is the same as that of the ac sampling shaping circuit 104, so that the analog-to-digital conversion processing circuit 101 performs ac detection at each sampling point and power supply on-off control under a corresponding detection result.
In this embodiment, after the ac sampling signal at the ac sampling point is obtained by the ac sampling and shaping circuit 104, the ac sampling signal is processed by the analog-to-digital conversion processing circuit 101, and when the analog-to-digital conversion processing circuit 101 determines that the ac sampling signal obtained by the ac sampling and shaping circuit 104 meets the start requirement of the wind profile radar, for example, when the voltage of the utility power is within a normal range (180V to 260V), the utility power is directly connected to the transmitting cabinet and the receiving cabinet in the wind profile radar, or when the voltage of the utility power exceeds the normal range but the electric quantity of the uninterruptible power supply is sufficient, the battery inside the uninterruptible power supply is used to supply power to the wind profile radar, so as to maintain the normal operation of the wind profile radar system. Specifically, in practical application, after the acquired ac sampling signal meets the start requirement of the wind profile radar, the first switch circuit 105 may be controlled to be turned on according to the switch control signal output by the analog-to-digital conversion processing circuit 101, so that the first solid-state ac relay 102 and the second solid-state ac relay 103 are closed, the loop between the uninterruptible power supply of the wind profile radar and the transmitting cabinet and the loop between the uninterruptible power supply and the receiving cabinet are controlled to be turned on, and the commercial power received by the uninterruptible power supply or a battery inside the uninterruptible power supply supplies power to the transmitting cabinet and the receiving cabinet, so as to achieve self-start of the wind profile radar.
In practical application, if the voltage of the commercial power is in an abnormal range, the uninterruptible power supply in the wind profile radar can be controlled to supply power to the receiving cabinet and the transmitting cabinet through the internal battery of the uninterruptible power supply. And after the uninterrupted power supply supplies power for the receiving cabinet and the transmitting cabinet, judging whether the current electric quantity of the uninterrupted power supply is lower than a power-off threshold value or not according to the current electric quantity of the uninterrupted power supply, specifically the current electric quantity of an internal battery of the uninterrupted power supply, if the current electric quantity of the uninterrupted power supply is lower than the power-off threshold value, only keeping the power supply of the uninterrupted power supply to a computer in the wind profile radar, so that the limited electric quantity of the uninterrupted power supply can be provided for the computer, the working time of the computer is prolonged, and a remote operator has sufficient time to store radar data or execute other corresponding operations. Through the above description, it can be known that the wind profile radar can execute corresponding control operation according to actual conditions, so as to realize self-starting of the wind profile radar, ensure normal operation of the wind profile radar, and further improve the environment adaptability of the wind profile radar.
Specifically, in practical application, the power supply of the uninterrupted power supply to the transmitting cabinet and the receiving cabinet can be cut off in a mode that a remote operator sends a manual control instruction, and only the power supply to the computer is reserved.
It should be noted that, under the condition that the electric quantity of the ups is sufficient, the ups may be used to supply power to the transmitting cabinet and the receiving cabinet regardless of whether the voltage of the utility power is in the normal range, but in order to prolong the working time of the wind profile radar system and ensure the normal operation of the wind profile radar, the backup power supply function of the ups is generally only activated when the voltage of the utility power is not in the normal range, or the backup power supply function of the ups is activated after receiving the manual control command sent by the remote operator.

Furthermore, in the two specific implementation modes of the scheme for realizing the temperature monitoring of the preset temperature sensitive element in the wind profile radar, the control signal generated by the analog circuit is simple and direct, and the stability is good; the control signal generated by the digital circuit is relatively complex, but can realize more complex control functions, so that in practical application, the optimal control signal can be selected by the two-way dial switch circuit 605 according to practical situations.
