Description
Technical Field
The invention relates to the technical field of protection locks, in particular to an electromechanical protection lock switch system with low power consumption.
Background
In the electromechanical protection lock switch, an electromagnet is generally used as a driving force and holding device; the conventional electromechanical protection lock switch uses the same constant voltage to control the switch and maintain the locking; according to the characteristics of the electromagnet, in the initial state of the electromagnet, only a part of the moving part armature in the electromagnet is in the magnetic field generated by the energized coil, so that the initial pushing force or pulling force of the electromagnet is very small (as shown in fig. 2). However, in the initial state, the moving part needs to bring the locking bar mechanism connected with the moving part from the static state to the moving state. When the armature of the electromagnet drives the locking rod mechanism to move to the holding state, all the armatures are in the magnetic field of the energized coil, and the holding force reaches the maximum (as shown in figure 3). The initial force and the holding force are changed in geometric progression on the movement stroke according to the characteristics of the electromagnet. The disadvantage of the conventional electromechanical protective lock is that in order to increase the initial movement force of the switch, the operating voltage needs to be increased to a relatively high level; while the electromagnet has a very large holding force once the armature moves to the holding state, the use of the same voltage to maintain the electromagnet in operation will generate a very large power consumption. This power consumption in turn affects the operation of the electromagnet: the lock protection switch is usually in a sealed state, the heat cannot be dissipated outwards, so that the temperature rise of a product is overhigh, danger is easy to occur, and the application environment is limited; the temperature of the electromagnet is increased, so that the resistance of the coil per se is increased, and the current is reduced; as the temperature increases, the magnetic saturation characteristics of the magnet also decrease; under the dual action of the two reasons, the initial force of the electromagnet is reduced, and the switching voltage of the electromechanical protection lock can only be increased in order to meet the initial force capable of driving the lock rod to move; and in turn further increases power consumption and temperature rise.
Disclosure of Invention
The present invention provides a low power consumption electromechanical switch system for protecting a lock, so as to solve the above technical problems.
In order to achieve the purpose, the invention adopts the following technical scheme: a low-power electromechanical switch system for a protection lock comprises a low-power control system, wherein the low-power control system controls the voltage applied to an electromagnet by detecting the change of the position of a mechanical movement device of the protection lock through a locking detection device; when the mechanical movement device of the protection lock is in a locking and maintaining state, the voltage applied to the electromagnet is reduced from Vh to VL by the low-power-consumption control system, so that the power consumption is greatly reduced; when the mechanical movement device of the protection lock is in an initial state, the voltage applied to the electromagnet is recovered from VL to VH through the low-power-consumption control system, so that the large initial force of the electromagnet is still maintained when the door is locked or opened next time, the safety door lock can be freely opened/closed through automatic switching of the low-power-consumption control system, and the effective reduction of power consumption is realized.
The low-power consumption control system comprises a voltage conversion control circuit, a delay control circuit and a voltage reduction circuit, wherein when the mechanical movement device of the protection lock is in an initial state, the delay control circuit converts the control circuit to a high voltage Vh according to the state voltage of the device in a movement detection state; at the moment, the electromagnet of the protection lock is in a disconnected state, and even if a high voltage is applied to the electromagnet, almost no current flows in the electromagnet, and no power consumption is generated; when the protection lock is switched from the initial state to the holding state, a high voltage Vh is applied to the electromagnet at the moment, and a large initial force drives the lock rod and the connecting bracket to move to the holding state; when the mechanical movement device of the protection lock moves to a locking state, the position of the movement state detection device is not changed, the movement state detection device detects the movement change of the protection lock and can confirm that the protection lock is in a holding state, after the movement state detection device collects the signal change of the movement state detection device, a voltage conversion control circuit is controlled after a certain time delay, the driving voltage of the electromagnet is switched from Vh to VL subjected to module voltage reduction so as to maintain the electromagnet in a stable holding state, the electromagnet holding voltage VL is greatly reduced compared with the initial pushing voltage Vh, therefore, the power consumption of the protection lock is correspondingly greatly reduced, when the protection lock is restored to the initial state from the holding state, only the electromagnet control switch is switched off through the control circuit, the mechanical movement device of the protection lock is pulled back to the initial state through external force such as a spring, after the mechanical movement device of the protection lock is restored to the initial state, the movement state detection device detects the movement of the protection lock because the movement state detection device does not change, the protection lock can confirm that the protection lock is in the initial state, after the movement state detection device collects the movement state, the movement state detection device is delayed for a certain time delay, the protection lock is switched from the protection lock, the protection lock is not influenced by the low-voltage, and the operation of the electromagnet, the protection lock is not influenced by the operation of the electromagnet, and the protection lock, so that the protection lock is maintained in the protection lock, the protection lock is maintained at the initial state, and the protection lock is maintained, the protection lock is not influenced by the protection lock.
Compared with the prior art, the invention has the following advantages: the invention automatically switches through the low-power-consumption control system, the safety door lock can be freely opened and closed, and the effective reduction of power consumption is realized. The power consumption of the electromagnet is obviously reduced, and the power consumption can be reduced by at least over 50 percent through practical verification; the temperature rise of the product is effectively reduced by at least more than 10 ℃. The temperature rise of the product is reduced, so that the working voltage range of the system is expanded to a certain extent; the product use environment is also expanded.
