Description

Technical Field

[0001] The invention relates to a control method and a lamp based on a Hall switch. Background Art

[0002] Mechanical switches are commonly used gear adjustment switches in electronic products. However, existing sliding mechanical switches, whether they are single switches or assembled into the overall structure of electronic products, are difficult to meet waterproof requirements.

[0003] Taking lamps as an example, existing lamps can be turned on and off and adjusted in multiple gears through sliding mechanical switches; sliding mechanical switches need to be connected to the control components inside the lamp through the travel groove on the lamp body, and then by pushing the knob with the moving contact to slide, the moving contact piece is connected from one set of static contact pieces to another set of static contact pieces to realize circuit switching, so the inside of the lamp is connected to the outside world, and the sliding mechanical switch itself is not waterproof, so the overall lamp body structure is not waterproof or does not meet the waterproof requirements. However, the Hall switch converts the magnetic signal into an electrical signal through the contactless induction of a magnet and multiple Hall sensors to realize the gear adjustment function of the lamp, solving the waterproof problem of the existing sliding mechanical switch.

[0004] Generally speaking, the Hall switch assembly includes a sliding switch with a magnet and a switch plate corresponding to the sliding switch. The switch plate is provided with multiple Hall switches. When the sliding switch slides, the magnet triggers different Hall switches. The Hall switches send out electrical signals to switch the lamp on and off or switch different lighting gears. However, the Hall switch converts the magnetic signal into an electrical signal. When there is an external magnet close to the lamp in the external environment, it will interfere with the Hall switch, causing malfunction or drift, and causing the lamp to turn on abnormally. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a control method and a lamp based on a Hall switch to solve the above problems.

[0006] The present invention adopts the following scheme:

[0007] The present application provides a control method based on a Hall switch, comprising the following steps:

[0008] Acquire the initial state value of each Hall switch; the state value includes an action state value and a non-action state value;

[0009] Detecting the magnetic signal acting on each Hall switch and obtaining the duration of the magnetic signal on each Hall switch;

[0010] Maintaining the state value of the Hall switch whose duration of the magnetic signal is not greater than a preset first time threshold value, and switching the state value of the Hall switch whose duration of the magnetic signal is greater than the first time threshold value;

[0011] The current state values ​​of all Hall switches are obtained; if only one of the Hall switches has an action state value, the action corresponding to the Hall switch is executed; otherwise, it is determined that there is external magnetic field interference and the current state is maintained.

[0012] Furthermore, it also includes: when it is determined that the external magnetic field interference disappears, after reaching a set second time threshold, obtaining the state values ​​of all Hall switches, and performing corresponding actions according to the state values ​​of all Hall switches.

[0013] Furthermore, when only one magnetic signal acting on all the Hall switches is detected, it is determined that the external magnetic field interference disappears.

[0014] Furthermore, the second time threshold is greater than the first time threshold.

[0015] Furthermore, the first time threshold is set to 300ms, and the second time threshold is set to 1S.

[0016] Furthermore, the number of the Hall switches is at least three.

[0017] Furthermore, when the magnetic signal acts on the Hall switch, the state value of the Hall switch is an action state value.

[0018] Furthermore, the initial state is off, and the Hall switch includes a first Hall switch, a second Hall switch and a third Hall switch; when the magnetic signal acts on the third Hall switch, it is off, and when it acts on the first or second Hall switch, it is on.

[0019] The present invention also provides a lamp, which includes a Hall switch component and a processor, wherein the Hall switch component includes a sliding switch with a magnet and a switch board corresponding to the sliding switch, and a plurality of Hall switches are arranged on the switch board, and the Hall switch is electrically connected to the processor; and the processor is configured to execute the control method.

[0020] Furthermore, the lamp body of the lamp comprises a plastic inner shell and a metal outer shell sleeved on the plastic inner shell; the metal outer shell is an extruded aluminum shell.

[0021] Furthermore, a storage bin and a removable cover body are provided on the storage bin; a groove is provided between the four sides of the storage bin and the outer wall, and a sealing ring is provided on the groove; and a protruding rib corresponding to the groove is provided on the inner side of the cover body.

[0022] Furthermore, the switch plate is arranged on one side of the accommodating compartment, and the Hall switch on the switch plate is arranged toward the outside, and a sliding switch is correspondingly arranged on the outside of the accommodating compartment, and the magnet on the sliding switch is placed on the side close to the Hall switch.

[0023] Furthermore, sliding grooves for the sliding switch to slide are arranged on the outer wall of the accommodating bin and the outer wall of the cover body; a plurality of gear grooves are arranged on the outer wall of the accommodating bin and / or the outer wall of the cover body at intervals along the sliding reverse direction of the sliding switch; and the sliding switch is provided with a gear card point which is adapted to the gear groove and has elasticity.

[0024] By adopting the above technical solution, the present invention can achieve the following technical effects:

If it is a short external magnetic signal, the initial state is maintained; if it is an internal magnetic signal or a continuous external magnetic signal, the current state value of all Hall switches is obtained, and further judges whether only one Hall switch is in the action state value. If so, the action is performed, otherwise, further continuous detection is performed to see whether there is a magnetic signal leaving, and if no magnetic signal leaves, the initial state is maintained; if it is detected that a magnetic signal leaves, further detection is performed to see whether only one Hall switch is in the action state value, and if so, the action is performed; otherwise, continuous detection of the magnetic signal leaving is continued.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0040] Example

[0041] Combination Figure 1 As shown, this embodiment provides a control method based on a Hall switch, which can be applied to an electronic device (such as a lamp) having a Hall switch and is executed by a processor of the electronic device to implement the following steps:

[0042] S101: Acquire the initial state value of each Hall switch; the state value includes an action state value and a non-action state value.

[0043] In this embodiment, the processor of the electronic device is electrically connected to each Hall switch and is capable of obtaining the state value of each Hall switch. The state value of the Hall switch includes an action state value and a non-action state value. When the magnetic signal acts on the Hall switch, the state value of the Hall switch is an action state value, and when the magnetic signal does not act on the Hall switch, the state value of the Hall switch is a non-action state value.

[0044] Take a lamp with three gears as an example, that is, it includes a first Hall switch, a second Hall switch and a third Hall switch, which are used to control the first gear, the second gear and off of the lamp lighting respectively. Specifically, in this embodiment, when the state value (RA) of the Hall switch is 0, it is an action state, and when the state value (RA) is 1, it is a non-action state. Figure 2 As shown in the table, when the state value (RA1) of the first Hall switch is 1, the state value (RA2) of the second Hall switch is 1, and the state value (RA3) of the third Hall switch is 0, the lamp is in the initial state (RA1=1, RA2=1, RA3=0), and the lamp lighting is turned off. When the state value of the first Hall switch is 0, the state value of the second Hall switch is 1, and the state value of the third Hall switch is 1, the lamp is in the first level lighting state (RA1=0, RA2=1, RA3=1); when the state value of the first Hall switch is 1, the state value of the second Hall switch is 0, and the state value of the third Hall switch is 1, the lamp is in the second level lighting state (RA1=0, RA2=1, RA3=0).

[0045] Of course, in other embodiments, the lamp may have only two states, on and off, that is, when the state value (RA1) of the first Hall switch is 1, the state value (RA2) of the second Hall switch is 1, and the state value (RA3) of the third Hall switch is 0, the lamp is in the off state (RA1=1, RA2=1, RA3=0); and when the state value (RA1) of the first Hall switch is 0, the state value (RA2) of the second Hall switch is 1, and the state value (RA3) of the third Hall switch is 1, or the state value (RA1) of the first Hall switch is 1, the state value (RA2) of the second Hall switch is 0, and the state value (RA3) of the third Hall switch is 1, the lamp is in the on state (RA1=0, RA2=1, RA3=1 or RA1=1, RA2=0, RA3=1).

[0046] S102: Detect the magnetic signal acting on each Hall switch, and obtain the duration of the magnetic signal on each Hall switch.

[0047] S103: Maintain the state value of the Hall switch whose duration of the magnetic signal is not greater than a preset first time threshold, and switch the state value of the Hall switch whose duration of the magnetic signal is greater than the first time threshold.

[0048] S104: Obtain the current state values ​​of all Hall switches; if only one of the Hall switches has an action state value, execute the action corresponding to the Hall switch; otherwise, determine that there is external magnetic field interference and maintain the current state.

[0049] In this embodiment, the sources of magnetic signals can be roughly divided into two types. One is generated by the sliding switch with a magnet corresponding to the Hall switch. This magnetic signal only acts on one Hall switch at a time and is relatively stable. The other is generated by an external magnetic interference source. The magnetic signal generated by the external magnetic interference source may be short-lived or continuous. In addition, it may be applied to multiple Hall switches at the same time, so it is necessary to filter the external magnetic field interference.

[0050] First, this embodiment determines the duration of the magnetic signal input. If the magnetic signal is not greater than the preset first time threshold, it means that the magnetic signal is a short-term external magnetic field interference and should be filtered. That is, under the action of this magnetic signal, although the Hall switch senses the magnetic signal, the processor will keep the state value of the Hall switch unchanged. For example, a Hall switch senses a magnetic signal, and its state value changes from 1 to 0, but changes back to 1 within the first time threshold. After processing, the processor still keeps the state value of the Hall switch as 1, and does not process the matter of 0.

[0051] In this embodiment, the first time threshold here can be set to 300ms, for example, which is an empirical value, and is the shortest reaction time required for a normal person to push the slide switch. Once it is lower than this shortest reaction time, it is considered that the magnetic signal is not generated by the user operating the slide switch.

[0052] In this embodiment, if the duration of the magnetic signal input is greater than the first time threshold, it means that the generation of the magnetic signal may be generated by a sliding switch with a magnet or by continuous external magnetic field interference. At this time, considering that normally there should be only one Hall switch in the action state value without interference, this embodiment further determines whether there is external magnetic field interference by determining whether there is only one Hall switch in the action state value, that is, if only one Hall switch has an action state value, it is considered that the magnetic signal is generated by the magnet on the sliding switch, and the action corresponding to the Hall switch is performed, such as turning off the lamp or switching the lighting state of the lamp. Otherwise, it is determined that there is external magnetic field interference, and the current initial state value is maintained.

[0053] Thereafter, when it is determined that the external magnetic field interference disappears, after reaching the set second time threshold, the state values ​​of all the Hall switches are obtained, and corresponding actions are performed according to the state values ​​of all the Hall switches.

[0054] In this embodiment, after determining that there is a continuous external magnetic field interference, all operations on the lamp will be temporarily regarded as invalid operations. However, after the external magnetic field interference, the user's operations need to be restored.

[0055] Specifically, when only one magnetic signal is detected acting on all the Hall switches, it is determined that the external magnetic field interference disappears. Then, after judging that the external magnetic field interference disappears and reaches a set second time threshold, the processor obtains the state values ​​of all the Hall switches again and performs corresponding actions according to the state values ​​of all the Hall switches.

[0056] This can effectively prevent external magnetic signals from interfering with the Hall switch and causing malfunction or drift, which could result in abnormal switching or shifting of electronic products.

[0057] To facilitate understanding of the present invention, the application of the present invention is described below with a practical example, wherein the practical example still takes a lamp with three gears as an example, but the use scenario of the present invention is not limited thereto.

[0058] Specific work process, such as Figure 3 As shown:

[0059] Take the initial state of the light-off state (ie, RA1=1, RA2=1, RA3=0) as an example.

[0060] When a magnet approaches, it is determined whether the magnetic signal input by the magnet lasts for the first set time threshold, such as 300ms; that is, it is detected whether the duration of the change of the state value of each Hall switch is greater than the first time threshold 300ms. If not, the initial light-off state is maintained, which means that the external magnetic field interference flashes by the lamp. If it is greater, the next step of judgment is carried out.

[0061] Obtain the state value of each Hall switch, and determine whether only the first Hall switch or the second Hall switch is in the action state (i.e., the state value RA=0). If only one of the Hall switches is in the action state, perform the action. Specifically, the state value of the first Hall sensor or the second Hall sensor changes from 1 to 0, and the state value of the third Hall sensor changes from 0 to 1, i.e., RA1=0, RA2=1, RA3=1, or RA1=1, RA2=0, RA3=1. At this time, the lamp is in the light-on state, i.e., the first gear lighting or the second gear lighting is turned on. This situation represents the normal state of pushing the lamp switch to switch the lamp.

[0062] If more than one of the Hall switches is in the action state, that is, the state values ​​of two or three of the Hall switches may be 0, which means that there is external magnetic field interference in the external environment near the lamp. At this time, the initial light-off state is maintained and the next step is carried out.

[0063] Continue to detect whether a magnetic signal leaves, that is, detect whether the state value of each Hall switch changes; if the magnetic signal is not detected to leave, that is, the state value of each Hall switch does not change, then continue to maintain the initial light-off state; if the magnetic signal is detected to leave, then the Hall state value will change, and proceed to the next step.

[0064] Detect whether only one of the Hall switches is in an action state, and determine whether the action state lasts for a set second time threshold, such as 1S. If the action state lasts for the set second time threshold, execute the action. Otherwise, execute the previous step to continue to detect whether the external magnetic field interference has left.

[0065] When the lamp is in the on state and there is magnetic input, the above steps are repeated to continue to determine whether the signal is an external magnetic signal or a magnetic signal on the lamp switch, and then determine whether to perform an action.

[0066] Among them, the first time threshold and the second time threshold can be set according to actual usage and external environment conditions, which will not be elaborated in detail here.
