Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] The present invention adopts the current overload protector as a detection device, which is installed in the motor control circuit of the antenna lifting platform to detect the working current value of the motor in real time, and implement the in-position detection and judgment during the lifting process of the platform. See how it works figure 1 shown, where figure 1 NC in means normally open, NO means normally closed, and A means contactor coil.

[0023] A vehicle-mounted lifting mechanism in-position detection circuit, including a motor power supply main circuit and an auxiliary control circuit; wherein, the current overload protector KZ is connected to the motor power supply main circuit, and the power supply is respectively connected to the contactor KM1 and the contactor KM2 through the current overload protector The ma...

Abstract

The invention discloses a vehicle-mounted lifting mechanism in-place detection circuit and method. The detection circuit comprises a power source, a current overload protector, a motor power supply main loop and an auxiliary control loop, wherein the current overload protector is connected to the motor power supply main loop; in the motor power supply main loop, a power supply is respectively connected with a contactor KM1 and a contactor KM2 through a current overload protector, and the contactor KM1 and the contactor KM2 control positive and negative rotation of a motor; the power supply, the current overload protector and a coil of a relay form a power supply loop; and a normally open contact of the relay is connected in parallel with a normally open contact of the current overload protector. On one hand, full-automatic control can be achieved, and manual participation is not needed; and on the other hand, devices such as a travel switch or a proximity sensor adopted for existing detection do not need to be installed, so that the technical defects caused by corresponding devices do not exist.

Description

technical field [0001] The invention relates to the technical field of in-position detection of a lifting mechanism, in particular to a circuit and method for in-position detection of a vehicle-mounted lifting mechanism. Background technique [0002] The vehicle-mounted antenna is a common vehicle-mounted device in the field of existing communication vehicles. Usually, this type of antenna is a relatively large device. In order to realize the normal transmission and reception of antenna signals, the antenna will be installed on a lifting platform, and the lifting platform will be driven by a motor. Up and down to realize the adjustment of the antenna height position. The lifting platform is located in the compartment, and when working, the lifting platform needs to be raised to the roof to be in sealing contact with the roof. Since the working environment may be rainy, snowy or dusty, when the lifting platform rises to the set position, it is necessary to consider whether t...
