Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent monitoring and fault detection, and in particular relates to a lamp inspection control circuit and a lamp inspection method based on multiple monitoring platforms. Background Art

[0002] In the field of intelligent monitoring, unattended situations often exist. When unattended, before judging the warning or alarm information, we must first determine whether the monitoring device itself is good or bad, that is, we must first determine whether the monitoring platform itself has no faults. This task seems easy to achieve under a single monitoring platform, but when it is expanded to multiple platforms, things become a bit complicated.

[0003] In order to realize fault detection under multiple monitoring platforms and achieve the requirements of reducing design complexity and rapid response, it is urgent to propose a lamp inspection control method based on multiple monitoring platforms. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the present invention is: in order to overcome the shortcomings of the existing multi-monitoring platform fault detection technology, specifically, the problems of too complex design, too high cost and low detection reliability under multiple platforms, a lighting inspection control method is designed that can be used for monitoring equipment across multiple platforms to quickly locate the quality of various lighting modules of the monitoring equipment.

[0006] (II) Technical solution

[0007] In order to solve the above technical problems, the present invention provides a lighting inspection control circuit based on multiple monitoring platforms, including multiple lighting modules; all lighting modules are lighting modules of the monitoring platform;

[0008] All lighting modules are: the positive pole is powered by a DC power supply; the negative pole is connected to the positive poles of three diodes, and a control terminal is added between the negative pole of the first diode and the digital ground. This control terminal is a dry contact, and each dry contact consists of two points. When the external input signal short-circuits these two dry contacts, a loop is formed, and the lighting module lights up, which can realize the first lighting mode; the negative pole of the second diode is connected to the self-starting light detection control terminal, which can realize the second lighting mode; the negative pole of the third diode is connected to the key light detection control terminal, which can realize the second lighting mode;

[0009] The second lighting mode is the self-starting lighting inspection mode, and the third lighting mode is the key-pressing lighting inspection mode. In these two lighting inspection modes, all lighting modules are connected in parallel, that is, when a power supply circuit is formed in any mode, all lighting modules should light up at the same time to perform fault detection; and the self-starting lighting inspection mode comes first, and the key-pressing lighting inspection mode comes later, that is, the self-starting lighting inspection mode will take effect after the monitoring platform is powered on, and the key-pressing lighting inspection mode is a manual detection mode.

[0010] Preferably, for all lighting modules, a relay is also connected between the self-starting light detection control end connected to the cathode of the second diode and the digital ground to realize control, and the control signal comes from the main control module of the monitoring platform. When the main control module is powered on, it will send a light detection instruction to the control end of the relay, and then the relay will be attracted to form a loop, so that the lighting module can be lit in the self-starting light detection mode.

[0011] Preferably, for all lighting modules, a button with self-reset is connected between the button light detection control terminal connected to the cathode of the third diode and the digital ground. When the button is pressed manually, a circuit is formed, so that the lighting module can be lit in the button light detection mode. When the hand is released, the button is restored, forming a circuit break, and the lighting module is turned off.

[0012] Preferably, the DC power supply is provided locally.

[0013] The invention also provides a lamp inspection method realized by using the control circuit.

[0014] Preferably, the method comprises the following lamp inspection steps:

[0015] Step 1. Each monitoring platform is powered on and the main control module of each monitoring platform is started;

[0016] Step 2. After the main control module starts normally, it sends a self-starting light inspection command to the control end of the relay, and the relay is energized;

[0017] Step 3. After the relay is energized, a circuit is formed and all the lighted modules should light up. At this time, if there are lighted modules that are not lit, a secondary light inspection operation is required, that is, execute step 4 to enter the key light inspection mode. If all the lighted modules are lit, execute step 8.

[0018] Step 4. Press the button manually to form a circuit and observe the lighted module that is not lit in the self-starting light detection mode;

[0019] Step 6. If the module that is not lit still does not light up, the fault can be located and it is determined that the module that is lit has a fault;

[0020] Step 7. After the repair and replacement, press the button again to check the quality of all the light modules;

[0021] Step 8. After confirming that all lighting modules are normal, each monitoring platform starts normal intelligent monitoring tasks, and performs lighting and extinguishing operations on the lighting modules through the control terminals of each lighting module.

[0022] The invention also provides an application of the circuit in the field of intelligent monitoring technology.

[0023] The invention also provides an application of the circuit in the technical field of fault detection.

[0031] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples.

[0032] Combine the following Figure 1 The light inspection control principle block diagram shown in the figure is as follows: Figure 2 The self-starting lamp detection principle block diagram shown in Figure 3 The key-operated light detection principle block diagram shown further describes a light detection control circuit and a light detection method based on multiple monitoring platforms of the present invention.

[0033] like Figure 1 As shown, a lighting inspection control circuit based on multiple monitoring platforms provided by the present invention includes multiple lighting modules; all lighting modules are lighting modules of the monitoring platform;

[0034] All lighting modules are: the positive pole is powered by a DC power supply, which is provided locally and has nothing to do with external input; the negative pole is connected to the positive poles of three diodes, and a control terminal is added between the negative pole of the first diode and the digital ground. This control terminal is a dry contact, and each dry contact consists of two points. When the external input signal short-circuits these two dry contacts, a loop is formed, the lighting module lights up, and an alarm message is displayed, which can realize the first lighting mode; the negative pole of the second diode is connected to the self-starting light detection control terminal 1-1, which can realize the second lighting mode; the negative pole of the third diode is connected to the key light detection control terminal 2-1, which can realize the second lighting mode;

[0035] The second lighting mode is the self-starting lighting inspection mode, and the third lighting mode is the key-pressing lighting inspection mode. In these two lighting inspection modes, all lighting modules are connected in parallel, that is, when a power supply circuit is formed in any mode, all lighting modules will light up at the same time to detect faults; and the self-starting lighting inspection mode comes first, and the key-pressing lighting inspection mode comes later, that is, the self-starting lighting inspection mode will take effect after the monitoring platform is powered on, and the key-pressing lighting inspection mode is a manual detection mode. The three diodes connected in parallel between the negative end of each lighting module and the digital ground isolate these three lighting modes.

[0036] Among them, the lighting module does not limit the style and model of the lamp. It only needs one end to be connected to the positive pole, and the other end is connected to three diodes in parallel and then connected to the digital ground.

[0037] In the self-starting lighting inspection mode, each monitoring platform does not need to perform complex control. It only needs to give a dry contact connection signal after the equipment on each monitoring platform is started.

[0038] The button light inspection mode is an auxiliary means of self-starting automatic light inspection, but it is more reliable. It is implemented by using a reinforced self-reset button with a protective cover. It can detect the quality of all monitoring platform lighting modules with one button.

[0039] like Figure 2 As shown, a relay is also connected between the self-starting light inspection control terminal 1-1 and the digital ground to realize control, and the control signal comes from the main control module of the monitoring platform. When the main control module is powered on, it will send a self-starting light inspection instruction to the control end of the relay, and then the relay will be energized to form a loop, so that the lighting module can light up in the self-starting light inspection mode.

[0040] like Figure 3 As shown, a button with self-reset is connected between the button light detection control terminal 2-1 and the digital ground. When the button is pressed manually, a circuit is formed to light up the lighting module in the button light detection mode. When the hand is released, the button is restored, forming a circuit break, and the lighting module is extinguished.

[0041] The specific steps of the lamp inspection method implemented by the above control circuit are as follows:

[0042] Step 1. Each monitoring platform is powered on and the main control module of each monitoring platform is started;

[0043] Step 2. After the main control module starts normally, it sends a self-starting light inspection command to the control end of the relay, and the relay is energized;

[0044] Step 3. After the relay is energized, a circuit is formed and all the light modules should light up. At this time, if there are light modules that are not lit, a secondary light inspection operation is required, that is, execute step 4 to enter the key light inspection mode.

[0045] Step 4. Press the button manually to form a circuit. All the lighted modules should light up. Pay special attention to the lighted modules that are not lit in the self-starting light inspection mode.

[0046] Step 6. If the module that is not lit still does not light up, the fault can be located and it is determined that the module that is lit has a fault;

[0047] Step 7. After the repair and replacement, press the button again to check the quality of all the light modules;

[0048] Step 8. After confirming that all lighting modules are normal, each monitoring platform starts normal intelligent monitoring tasks, and performs lighting and extinguishing operations on the lighting modules through the control terminals of each lighting module.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
