The number of electronic forklift trucks has been beating. The person who has used electronic forklift scales must know that there are various problems with improper use of electronic instruments. For example, a friend may ask, the number of electronic forklift trucks has been beating How is this going? This question is actually very simple. Let's introduce it to you today.
The number of electronic forklift trucks has been beating and there are several reasons.
The first point:
The reason is that the line and the possibility of dust or debris, need to be opened and cleaned.
Second point:
The reason is that there is a problem with the sensor of the electronic lift truck scale. The sensor needs to be checked and trimmed.
The third point:
The reason is that there is an abnormal situation of stable voltage. This kind of problem needs to deal with the junction box to see how the voltage is and check the circuit.
fourth point:
It is the circuit of the operational amplifier that has the unusual situation, this also needs to carry on the inspection, eliminates other problems.
Fifth:
The A/D circuit of the junction box has abnormal conditions. There are two points: the weighing of the four sensors of the weighing pan is inaccurate and the data is missing.
Generally, the number of such electronic forklift truck scales has been beating. There is a great possibility that the sensor of the forklift scale has a problem. You need to exclude some of the above reasons. If it is the cause of the sensor, you need to The sensor is processed.
LED Streetlight
Led street light, compared with the traditional lighting technology, led lamps and lanterns have higher efficiency, and longer service life.Thus become the preferred bulb type, in order to reduce the energy consumption of indoor/outdoor lighting, get energy saving effect.
For street lamps, higher efficiency and longer life are indispensable for cost reduction.Designed for the LED power supply switch power supply, also must have a high efficiency and durability, to ensure that it has as long as the LED life without maintenance.Here, the resonant converter is one of the most popular power supply topology, this is because compared with previous power supply topology, their performance has brought higher power efficiency, and can reduce EMI.Soft switch is an important characteristic of resonant converter.But the resonant converter used in parasitic diodes (bodydiode) can sometimes lead to system failure.Stored in the parasitic diodes charge must be clear, to avoid large current and voltage surge, including topology structure of high dv/dt and di/dt.
