Description

Technical Field

[0001] The utility model relates to the technical field of medium-wave antenna switch control driving devices, in particular to a medium-wave antenna switch control driving device. Background Technique

[0002] The switching system for high-power output of medium-wave transmitting antennas and dummy loads, etc. is a professional device in the industry. It is highly specialized and often needs to be customized. The commonly used antenna switching switch is driven by a motor for switching. The relay controlling the motor outputs a control signal relative to the industrial control computer of the transmitting station's intelligent monitoring system, which belongs to high-power driving. Therefore, it is necessary to design a medium-wave antenna switch control driving device.

[0003] The existing design levels vary, and the versatility is not strong. In some cases, adding chip programming design is superfluous and makes the overall circuit more complex. The driving relays are not reduced, resulting in an increased failure rate.

[0004] Therefore, we propose a medium-wave antenna switch control driving device to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the utility model is to provide a medium-wave antenna switch control driving device to solve the problems in the above-mentioned background technique, such as the uneven existing design levels and the lack of strong versatility. In some cases, adding chip programming design is superfluous and makes the overall circuit more complex. The driving relays are not reduced, resulting in an increased failure rate.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A medium-wave antenna switch control driving device, including a medium-wave antenna switch control driving box. The medium-wave antenna switch control driving includes an antenna switching driving relay, an A-machine antenna combining intermediate relay, a B-machine antenna combining intermediate relay, an A-machine antenna switch switching-in-place interlock relay, and a B-machine antenna switch switching-in-place interlock relay. The A-machine antenna combining intermediate relay and the B-machine antenna combining intermediate relay are respectively used to control the combined or separated state of the antenna. The A-machine antenna switch switching-in-place interlock relay and the B-machine antenna switch switching-in-place interlock relay are respectively used to ensure that when the antenna is switched, only one antenna is in the active state, avoiding the interference or damage to the equipment caused by the simultaneous connection of two antennas. The medium-wave antenna switch control driving box contains an A-machine and a B-machine. The A-machine main unit and the B-machine standby unit are in a non-high-voltage state. The antenna is in the B-machine position. When the medium-wave antenna switch control driving box receives the A-machine combined high-voltage signal from the industrial control computer, the antenna switching driving relay rotates. When the A-machine antenna reaches the position, the medium-wave antenna switch control driving box sends out the A-machine antenna status quantity to the industrial control computer, allowing the A-machine to combine high voltage and stopping sending out the motor working signal.

[0007] Preferably, a dummy load cooling fan power supply driving relay for controlling the start and stop of a cooling fan, an antenna switch driving motor for controlling the rotation or position adjustment of an antenna, and a dummy load fan motor for simulating a fan load in a real environment are further provided inside the medium wave antenna switch control and driving box. When the B machine uses a dummy load, the power supply is driven by the dummy load fan motor.

[0008] Preferably, the medium wave antenna switch control and driving box provides LED indications for the working states of the antenna and the dummy load.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] 1. By providing the medium wave antenna switch control and driving box, when the medium wave antenna switch control and driving box receives the A machine high voltage combination signal from the industrial control computer, the KM1 antenna switching driving relay rotates. When the A machine antenna is in place, the medium wave antenna switch control and driving box sends the A machine antenna status quantity to the industrial control computer, allowing the A machine to combine high voltage and stopping sending the motor working signal. When the switch is set to the manual position, the principle of antenna switching is similar to the automatic state. At this time, the industrial control computer cannot control the medium wave antenna switch control and driving box. Only by receiving the antenna position status quantity signal can the automatic and manual modes be easily switched, and the driving motor be controlled to implement antenna switching. The manual intervention electric switch switching function can be realized in the case of the paralysis of the intelligent control system and the network. Description of the Drawings

[0014] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0015] Embodiment 1: Please refer to Figure 1 and Figure 2 , the medium wave antenna switch control driving device, including the medium wave antenna switch control driving box 1, the medium wave antenna switch control driving box 1 includes the KM1 antenna inversion driving relay 11, the JK1A machine antenna combination intermediate relay 12, the JK2B machine antenna combination intermediate relay 13, the JK3A machine antenna switch inversion in-place interlock relay 14 and the JK4B machine antenna switch inversion in-place interlock relay 15. The JK1A machine antenna combination intermediate relay 12 and the JK2B machine antenna combination intermediate relay 13 are respectively used to control the combined or separated state of the antenna. The JK3A machine antenna switch inversion in-place interlock relay 14 and the JK4B machine antenna switch inversion in-place interlock relay 15 are respectively used to ensure that when the antenna is switched, only one antenna is in the active state, avoiding interference or equipment damage caused by two antennas being connected simultaneously. The medium wave antenna switch control driving box 1 contains machine A and machine B. The main machine of machine A and the standby machine of machine B are in a non-high-voltage state, and the antenna is in the position of machine B. When the medium wave antenna switch control driving box 1 receives the high-voltage signal for combining machine A from the industrial control computer, the KM1 antenna inversion driving relay 11 rotates. When the antenna of machine A is in place, the medium wave antenna switch control driving box 1 sends the antenna status quantity of machine A to the industrial control computer, allowing machine A to combine high voltage and stopping sending the motor working signal. When the switch is set to the manual position, the principle of antenna inversion is similar to the automatic state. At this time, the industrial control computer cannot control the medium wave antenna switch control driving box 1, and only receives the antenna position status quantity signal.

[0016] Inside the medium wave antenna switch control driving box 1, there is also provided the KM2 dummy load cooling fan power supply driving relay 16 for controlling the start and stop of the cooling fan, the M1 antenna switch driving motor 17 for controlling the rotation or position adjustment of the antenna, and the M2 dummy load fan motor 18 for simulating the fan load in the real environment. When machine B uses the dummy load, the power supply is driven by the dummy load fan motor 18.

[0017] The medium wave antenna switch control driving box 1 provides LED indications for the working states of the antenna and the dummy load.

[0018] In this embodiment: The main unit of Machine A and the standby unit of Machine B are in a non-high-voltage state, and the antenna is at the position of Machine B. When the medium-wave antenna switch control drive box 1 receives the high-voltage signal for Machine A from the industrial control computer, the KM1 antenna switching drive relay 11 rotates. When the antenna of Machine A reaches the position, the medium-wave antenna switch control drive box 1 sends the antenna status quantity of Machine A to the industrial control computer, allowing Machine A to switch on high voltage and stopping sending the motor working signal. When the change-over switch is set to the manual position, the principle of antenna switching is similar to the automatic state. At this time, the industrial control computer cannot control the medium-wave antenna switch control drive box 1. Only when receiving the antenna position status quantity signal, it can simply realize the switching between the automatic and manual modes, control the drive motor to implement antenna switching, and can realize the manual intervention electric change-over switch switching function in the case of the paralysis of the intelligent control system and the network. Using the auxiliary contact of the drive relay to lock can prevent misoperation in any situation, reliably protect the equipment and greatly simplify the circuit design.

[0019] Working principle: The main unit of Machine A and the standby unit of Machine B are in a non-high-voltage state, and the antenna is at the position of Machine B. When the medium-wave antenna switch control drive box 1 receives the high-voltage signal for Machine A from the industrial control computer, the KM1 antenna switching drive relay 11 rotates. When the antenna of Machine A reaches the position, the medium-wave antenna switch control drive box 1 sends the antenna status quantity of Machine A to the industrial control computer, allowing Machine A to switch on high voltage and stopping sending the motor working signal. When the change-over switch is set to the manual position, the principle of antenna switching is similar to the automatic state. At this time, the industrial control computer cannot control the medium-wave antenna switch control drive box 1. Only when receiving the antenna position status quantity signal, it can simply realize the switching between the automatic and manual modes.
