Since January 1, 2019, the Ministry of Industry and Information Technology has announced mandatory measures for M1 vehicles (passenger cars with no more than 9 seats including the driver’s seat.) The installation of tire pressure detectors has caused industry professionals. Among them, once the tire pressure monitoring market breaks out, whether mass production can meet the demand for production capacity has also become a core discussion point. Why is the topic of tire pressure monitoring still a hidden concern after many years of mass production? How can this be solved?

First of all, why is the mandatory installation of tire pressure monitoring imperative?

Taking a set of network data as an example, before the mandatory installation of tire pressure detectors in the United States, as many as 80% of traffic accidents caused by tires, of which accidents caused by excessive tire pressure accounted for 20%, and insufficient tire pressure accounted for 57%. After the implementation of mandatory tire pressure monitoring, the number of puncture accidents has dropped to 3%. And 70%-80% of the over-speed highway traffic accidents issued by our country are also caused by tire pressure, which makes the mandatory installation of tire pressure monitoring imperative. The compulsory installation of tire pressure monitoring is equivalent to adding a “protective net” to the driver’s life safety.

What is the focus of the current industry capacity concerns?

According to rough statistics, there are nearly 200 million cars in stock in our country. Once such a large number of vehicles explode, the demand will be astonishing. The Ministry of Industry and Information Technology documents indicate that on January 1, 2020, the national law will require all types of vehicles to be compulsory to install tire pressure monitors, otherwise they will not be able to legally go on the road. After mentioning it for many years, why is there still a hidden worry? The reason is that the early intervention is basically the original programming and debugging tools. During the development of the chip verification stage, many manufacturers use the original special programming tools to download one by one, not only to operate the board, but also to operate the host computer software. , This can be used normally in the case of low production capacity requirements in the early stage, but once mass production begins, the problem begins to break out, the production department frequently reports poor programming, the operation is cumbersome, and the engineers are also tired of running and guiding.

Why does this problem occur?

The core reason: the original debugging and burning tool itself is for R&D verification, not mass production.

The operation process of the original debugging tool is oriented to the special research and development, which may lead to frequent operation of the upper computer button, and may need to burn after each debugging connection, or use the printing string, buzzer and other methods to give feedback on the results. These have brought great difficulties to factory operators with weak professional knowledge systems. The most important thing is: R&D and debugging of burning equipment does not guarantee the yield rate. And the debugging and burning tools of each original factory basically only serve the chips of their own manufacturers. Once the auto parts manufacturers are involved in the burning of multiple chips, they need to replace the burning equipment frequently, resulting in a huge waste of product deployment man-hours and increasing Increased the R&D workload.

What chip mass production and burning requirements will be involved in tire pressure monitoring installation?

Let’s take a TPMS system of the ZLG official website solution as an example. This entire system is divided into a host, a Bluetooth chip, a probe, etc. Except for the core tire pressure detection chip, other chips related to the tire pressure monitoring solution may be in sync. There is a demand for batch programming during production. This is often not a one-time solution for the original factory debugging work, and traditional mass-produced burner manufacturers are often not familiar with the whole set of tire pressure monitoring programs, and cannot cover most of the possible uses in the burner/programmer support. The chips that are received cause frequent applications for additions every time they are added during use.

Solution reference:

The P800isp multi-channel online burner of ZLG Zhiyuan Electronics Co., Ltd., equipped with an independent operating system, can meet the factory’s full offline, one-key batch programming requirements, convenient operation, and can solve common tire pressure monitoring through multiple cascades. Issues related to online programming of the board, and wide coverage of tire pressure monitoring related chips, including SP series represented by Infineon SP37 and SP40Plus, Freescale tire pressure monitoring chips FXTH8709, FXTH8711 series, and NCK2912 from NXP /NCK2913 and other core tire pressure monitoring chips and related chips for tire pressure monitoring solutions. There is no need to prepare multiple original special burning tools, reducing equipment costs and management costs.
